-Notes on the Free Translation Project
-*************************************
-
- Free software is going international! The Free Translation Project
-is a way to get maintainers of free software, translators, and users all
-together, so that will gradually become able to speak many languages.
-A few packages already provide translations for their messages.
-
- If you found this `ABOUT-NLS' file inside a distribution, you may
-assume that the distributed package does use GNU `gettext' internally,
-itself available at your nearest GNU archive site. But you do _not_
-need to install GNU `gettext' prior to configuring, installing or using
-this package with messages translated.
-
- Installers will find here some useful hints. These notes also
-explain how users should proceed for getting the programs to use the
-available translations. They tell how people wanting to contribute and
-work at translations should contact the appropriate team.
-
- When reporting bugs in the `intl/' directory or bugs which may be
-related to internationalization, you should tell about the version of
-`gettext' which is used. The information can be found in the
-`intl/VERSION' file, in internationalized packages.
-
-Quick configuration advice
-==========================
-
- If you want to exploit the full power of internationalization, you
-should configure it using
-
- ./configure --with-included-gettext
-
-to force usage of internationalizing routines provided within this
-package, despite the existence of internationalizing capabilities in the
-operating system where this package is being installed. So far, only
-the `gettext' implementation in the GNU C library version 2 provides as
-many features (such as locale alias, message inheritance, automatic
-charset conversion or plural form handling) as the implementation here.
-It is also not possible to offer this additional functionality on top
-of a `catgets' implementation. Future versions of GNU `gettext' will
-very likely convey even more functionality. So it might be a good idea
-to change to GNU `gettext' as soon as possible.
-
- So you need _not_ provide this option if you are using GNU libc 2 or
-you have installed a recent copy of the GNU gettext package with the
-included `libintl'.
-
-INSTALL Matters
-===============
-
- Some packages are "localizable" when properly installed; the
-programs they contain can be made to speak your own native language.
-Most such packages use GNU `gettext'. Other packages have their own
-ways to internationalization, predating GNU `gettext'.
-
- By default, this package will be installed to allow translation of
-messages. It will automatically detect whether the system already
-provides the GNU `gettext' functions. If not, the GNU `gettext' own
-library will be used. This library is wholly contained within this
-package, usually in the `intl/' subdirectory, so prior installation of
-the GNU `gettext' package is _not_ required. Installers may use
-special options at configuration time for changing the default
-behaviour. The commands:
-
- ./configure --with-included-gettext
- ./configure --disable-nls
-
-will respectively bypass any pre-existing `gettext' to use the
-internationalizing routines provided within this package, or else,
-_totally_ disable translation of messages.
-
- When you already have GNU `gettext' installed on your system and run
-configure without an option for your new package, `configure' will
-probably detect the previously built and installed `libintl.a' file and
-will decide to use this. This might be not what is desirable. You
-should use the more recent version of the GNU `gettext' library. I.e.
-if the file `intl/VERSION' shows that the library which comes with this
-package is more recent, you should use
-
- ./configure --with-included-gettext
-
-to prevent auto-detection.
-
- The configuration process will not test for the `catgets' function
-and therefore it will not be used. The reason is that even an
-emulation of `gettext' on top of `catgets' could not provide all the
-extensions of the GNU `gettext' library.
-
- Internationalized packages have usually many `po/LL.po' files, where
-LL gives an ISO 639 two-letter code identifying the language. Unless
-translations have been forbidden at `configure' time by using the
-`--disable-nls' switch, all available translations are installed
-together with the package. However, the environment variable `LINGUAS'
-may be set, prior to configuration, to limit the installed set.
-`LINGUAS' should then contain a space separated list of two-letter
-codes, stating which languages are allowed.
-
-Using This Package
-==================
-
- As a user, if your language has been installed for this package, you
-only have to set the `LANG' environment variable to the appropriate
-`LL_CC' combination. Here `LL' is an ISO 639 two-letter language code,
-and `CC' is an ISO 3166 two-letter country code. For example, let's
-suppose that you speak German and live in Germany. At the shell
-prompt, merely execute `setenv LANG de_DE' (in `csh'),
-`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash').
-This can be done from your `.login' or `.profile' file, once and for
-all.
-
- You might think that the country code specification is redundant.
-But in fact, some languages have dialects in different countries. For
-example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The
-country code serves to distinguish the dialects.
-
- The locale naming convention of `LL_CC', with `LL' denoting the
-language and `CC' denoting the country, is the one use on systems based
-on GNU libc. On other systems, some variations of this scheme are
-used, such as `LL' or `LL_CC.ENCODING'. You can get the list of
-locales supported by your system for your country by running the command
-`locale -a | grep '^LL''.
-
- Not all programs have translations for all languages. By default, an
-English message is shown in place of a nonexistent translation. If you
-understand other languages, you can set up a priority list of languages.
-This is done through a different environment variable, called
-`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG'
-for the purpose of message handling, but you still need to have `LANG'
-set to the primary language; this is required by other parts of the
-system libraries. For example, some Swedish users who would rather
-read translations in German than English for when Swedish is not
-available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
-
- In the `LANGUAGE' environment variable, but not in the `LANG'
-environment variable, `LL_CC' combinations can be abbreviated as `LL'
-to denote the language's main dialect. For example, `de' is equivalent
-to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
-(Portuguese as spoken in Portugal) in this context.
-
-Translating Teams
-=================
-
- For the Free Translation Project to be a success, we need interested
-people who like their own language and write it well, and who are also
-able to synergize with other translators speaking the same language.
-Each translation team has its own mailing list. The up-to-date list of
-teams can be found at the Free Translation Project's homepage,
-`http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams"
-area.
-
- If you'd like to volunteer to _work_ at translating messages, you
-should become a member of the translating team for your own language.
-The subscribing address is _not_ the same as the list itself, it has
-`-request' appended. For example, speakers of Swedish can send a
-message to `sv-request@li.org', having this message body:
-
- subscribe
-
- Keep in mind that team members are expected to participate
-_actively_ in translations, or at solving translational difficulties,
-rather than merely lurking around. If your team does not exist yet and
-you want to start one, or if you are unsure about what to do or how to
-get started, please write to `translation@iro.umontreal.ca' to reach the
-coordinator for all translator teams.
-
- The English team is special. It works at improving and uniformizing
-the terminology in use. Proven linguistic skill are praised more than
-programming skill, here.
-
-Available Packages
-==================
-
- Languages are not equally supported in all packages. The following
-matrix shows the current state of internationalization, as of May 2003.
-The matrix shows, in regard of each package, for which languages PO
-files have been submitted to translation coordination, with a
-translation percentage of at least 50%.

- Some counters in the preceding matrix are higher than the number of
-visible blocks let us expect. This is because a few extra PO files are
-used for implementing regional variants of languages, or language
-dialects.
-
- For a PO file in the matrix above to be effective, the package to
-which it applies should also have been internationalized and
-distributed as such by its maintainer. There might be an observable
-lag between the mere existence a PO file and its wide availability in a
-distribution.
-
- If May 2003 seems to be old, you may fetch a more recent copy of
-this `ABOUT-NLS' file on most GNU archive sites. The most up-to-date
-matrix with full percentage details can be found at
-`http://www.iro.umontreal.ca/contrib/po/HTML/matrix.html'.
-
-Using `gettext' in new packages
-===============================
-
- If you are writing a freely available program and want to
-internationalize it you are welcome to use GNU `gettext' in your
-package. Of course you have to respect the GNU Library General Public
-License which covers the use of the GNU `gettext' library. This means
-in particular that even non-free programs can use `libintl' as a shared
-library, whereas only free software can use `libintl' as a static
-library or use modified versions of `libintl'.
-
- Once the sources are changed appropriately and the setup can handle
-the use of `gettext' the only thing missing are the translations. The
-Free Translation Project is also available for packages which are not
-developed inside the GNU project. Therefore the information given above
-applies also for every other Free Software Project. Contact
-`translation@iro.umontreal.ca' to make the `.pot' files available to
-the translation teams.

- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-
- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; if not, write to the Free Software
- Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) year name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-
- * data/glr.c (YYRECOVERING): Define to be a function-like macro
- with no arguments, not as an object-like macro. This is for

-2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/getargs.c (usage): Back out yesterday's modification of the
- --help output so that we don't have to wait for translation before
- releasing 2.3.
-
-2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
-
- * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
- Problem reported by Akim Demaille.
-
-2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.

-
-2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
-
- * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
- shell, not within 'make', so that 'make' by an ordinary builder
- (using GNU make) does not worry about configuring gzip. This also
- works around a bug reported independently by Keith Thompson and by
- Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
- stderr rather than stdout, messing up the build logs.
-
-2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
- to make sure that YYID will never be unused. This fixes a 'make
- maintainer-check' failure caused by the recent changes to the 'Trivial
- grammars' test case, which caused g++ 4.1.0 to complain that YYID was
- not used.
- * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
-
-2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
- state before an empty RHS is always resolved here. Only the location
- of that state is guaranteed to be resolved, and that's enough. This
- fixes the remaining bug reported by Derek M. Jones in
- <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
- * tests/glr-regression.at (Uninitialized location when reporting
- ambiguity): Test the above case.
- Also, the embedded comments in this test case claim it checks the case
- of an empty RHS that has inherited the initial location. However, the
- corresponding LHS was already resolved, so yyresolveLocations didn't
- actually have reason to modify it. Fix this by forcing
- nondeterministic operation at the beginning of the parse.
-
-2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/c.m4 (b4_yy_symbol_print_generate):
- (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
- 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
- of the bugs reported today by Derek M Jones in
- <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
- * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
- defined to be a type name without parens or brackets.
- (Location Type): Similarly for YYLTYPE.
- * tests/regression.at (Trivial grammars): Put in a test for this
- bug that will be caught by 'make maintainer-check' (though not,

-2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
-
- * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use

- of AT_NAME_PREFIX when %name-prefix is not used.
-
-2006-03-12 Akim Demaille <akim@lrde.epita.fr>
-
- Apply --prefix to C++ skeletons too: they change the namespace.
- The test suite already exercize these cases.
- * data/c++.m4 (b4_namespace): New.
- * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.

-2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
- page. Say "you can use it" not "you may use it" as on the web page;
- we're describing capabilities not granting permission.

-
- * data/glr.c (yyresolveLocations): Rename local variables to avoid

- * tests/glr-regression.at
- (Uninitialized location when reporting ambiguity):
- Modify yylex so that it uses its argument, rather than trying
- to rely on ARGSUSED (which doesn't work for gcc with warnings).
- const char -> char const.
-
- * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
- Don't use tabs inside commands; it messes up 'ps'.

-
- Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
- * tests/glr-regression.at (Leaked semantic values when reporting
- ambiguity): New test case.
- * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
- yyabort rather than invoking yyFail, which invokes longjmp. Remove the
- now unnecessary yystackp parameter.
- (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
- destructors can be called.
-
- * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
- in existing testcases.
-
-2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Don't leak semantic values for parent RHS when a user action cuts the
- parser, and clean up related code a bit.
- * tests/glr-regression.at (Leaked merged semantic value if user action
- cuts parse): Rename to...
- (Leaked semantic values if user action cuts parse): ... this. Add check
- for leaked parent RHS values.
- * data/glr.c (yydestroyGLRState): In debugging output, distinguish
- between an unresolved state (non-empty chain of semantic options) and
- an incomplete one (signaled by an empty chain).
- (yyresolveStates): Document the interface. Move all manipulation of a
- successfully or unsuccessfully resolved yyGLRState to...
- (yyresolveValue): ... here so that yyresolveValue always leaves a
- yyGLRState with consistent data and thus is easier to understand.
- Remove the yyvalp and yylocp parameters since they are always just
- taken from the yys parameter. When reporting a discarded merged value
- in debugging output, note that it is incompletely merged. Document the
- interface.
- (yyresolveAction): If resolving any of the RHS states fails, destroy
- them all rather than leaking them. Thus, as long as user actions are
- written to clean up the RHS correctly, yyresolveAction always cleans up
- the RHS of a semantic option. Document the interface.

- declarations of malloc and free, to avoid problems with

- should fix Debian bug 340012

-
- * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Catch a
- configuration screwup "./configure CC=/opt/SUNWspro/bin/c89
- CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
- LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this
- messes up because C++ code is compiled in 32-bit mode but linked
- in 64-bit mode.

-2006-02-08 Paul Eggert <eggert@cs.ucla.edu>
-
- More portability fixes for problems summarized by Nelson H. F. Beebe.
-
- * doc/bison.texinfo (Calc++ Scanner): Work around a bug in flex
- 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
-
- * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
- nodist_PROGRAMS, since we don't need to actually compile the
- example if we're just doing a plain 'make'. This avoids bothering
- the installer unnecessarily about problems due to weird C++
- compilers.

-
- More portability fixes for problems summarized by Nelson H. F. Beebe.
-
- * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather

- not portable, according to Posix and the C standard, and it does
- not work with Sun C 5.7, where previous #line directives affect
- the working directory used in later #include "..." directives.

-
- * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
- that '#include <string>' works.
-
- * data/lalr1.cc (yytranslate_): No longer inline, to work around a
- porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
- "warning: sorry: semantics of inline function static data `const
- unsigned char translate_table[262]' are wrong (you'll wind up with
- multiple copies)".
-
- * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
- or, xor to not_, and_, or_, and xor_, respectively. This works
- around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
- random system header somewhere that includes the equivalent of
- <iso646.h>.
-
- * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
- -E" works; it apparently doesn't work with PathScale EKO Compiler
- Suite Version 2.0.
-
-2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
-
- During deterministic GLR operation, user actions should be able to
- influence the parse by changing yychar. To make this easier to fix and
- to make glr.c easier to evolve in general, don't maintain yytoken in
- parallel with yychar; just compute yytoken when needed.
- * tests/glr-regression.at (Incorrect lookahead during deterministic
- GLR): Check that setting yychar in a user action has the intended
- effect.
- * data/glr.c (yyGLRStack): Remove yytokenp member.
- (yyclearin): Don't set *yytokenp.
- (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
- yychar rather than *yytokenp to determine the current lookahead.
- Compute yytoken locally when needed.
- (yyparse): Likewise. Remove the local yytoken that yytokenp used to
- point to.
-
- * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
- after `--report' documentation.
-
-2006-01-30 Paul Eggert <eggert@cs.ucla.edu>

-
-2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
-
- * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
- all the test at once. This makes the output easier to read in the
- normal case.
-
- Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
- got from <http://bro-ids.org/download.html>. The bug is that
- when two actions appeared in succession, the second one was
- scanned before the first one was added to the grammar rule
- as a midrule action. Bison then output the incorrect warning
- "parse.y:905.17-906.36: warning: unused value: $3".
- * src/parse-gram.y (BRACED_CODE, action): These are no longer
- associated with a value.
- (rhs): Don't invoke grammar_current_rule_action_append.
- (action): Invoke it here instead.
- * src/reader.c (grammar_midrule_action): Now extern.
- (grammar_current_rule_action_append): Don't invoke
- grammar_midrule_action; that is now the scanner's job.
- * src/reader.h (last_string, last_braced_code_loc):
- (grammar_midrule_action): New decls.
- * src/scan-gram.l (last_string): Now extern, sigh.
- (last_braced_code_loc): New extern variable.
- (<INITIAL>"{"): Invoke grammar_midrule_action if the current
- rule already has an action.
- (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
- * tests/input.at (AT_CHECK_UNUSED_VALUES):
- Add some tests to check that the above changes fixed the bug.
-
-2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
- All used changed. Check whether the symbol has a destructor,
- not whether it is typed.
- * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
- that the values are still reported as unused. All line numbers
- adjusted.
-
-2006-01-23 Paul Eggert <eggert@cs.ucla.edu>
-
- Work around a bug in bro 0.8, which underparenthesizes its

- * data/lalr1.cc: Likewise.
- * data/yacc.cc: Likewise.
-
-2006-01-22 Paul Eggert <eggert@cs.ucla.edu>
-
- Work around a bug in Pike 7.0, and give the Pike folks a
- better way to override the usual int widths.
- * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
- user can override the types.
- (short): #undef, to work around a bug in Pike 7.0.
- (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
- (union yyalloc.yyss): Use yytype_int16 rather than short.
- All uses changed.

- * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
- (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
- * tests/regression.at (Web2c Actions): Adjust to above changes.
-
- * src/reader.c (check_and_convert_grammar): New function.
- (reader): Close the input file even if something went wrong during
- parsing. Minor file descriptor leak reported by twlevo.
-
- * src/assoc.c (assoc_to_string): Use a default: abort (); case
- to pacify gcc -Wswitch-default.
- * src/scan-gram.l (adjust_location): Use a default: break; case
- to pacify gcc -Wswitch-default.
- * src/scan-skel.h (skel_get_lineno, skel_get_in, skel_get_out):
- (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
- (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
- Move these decls to scan-skel.l, since they don't need to be
- visible elsewhere.
- * src/scan-skel.l: Accept the above decls.
- (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
- is used.

- isn't when semantic actions are deferred.
- In the yychar and yyclearin entries, add note about deferred semantic

-
- * data/glr.c (yyresolveValue): When merging semantic options, if at
- least one user action succeeds but a later one cuts the parse, then
- destroy the semantic value before returning rather than leaking it.
- (yyresolveStates): If a user action cuts the parse and thus
- yyresolveValue fails, ignore the (unset) semantic value rather than
- corrupting the yyGLRState, and empty the semantic options list since
- the user actions should have called all necessary destructors.
- Simplify code with YYCHK.
- * tests/glr-regression.at (Corrupted semantic options if user action
- cuts parse): New test case.
- (Undesirable destructors if user action cuts parse): New test case.
- Before applying any of this patch, this test case never actually failed
- for me... but only because the corrupted semantic options usually
- masked this bug.

- case.

- Use unlocked I/O for a minor performance improvement on hosts like

- patch.
-
-2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
-
- * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
- contains obsolete information and isn't worth distributing as a
- separate file anyway.
- * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
- (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

- as the one reported at the end of
- <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
- All callers changed to avoid the newline.
- (yyprocessOneStack): Output two lines rather than one, to accommodate

- reported by Joel E. Denny in
- <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
- (trivial change).

-2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
-
- * NEWS: Version 2.0b.
-
- * Makefile.am (SUBDIRS): Put examples before tests, so that
- "make check" doesn't finish with "All 1 tests passed".
-
- * tests/regression.at (Token definitions): Don't rely on
- AT_PARSER_CHECK for data that contains backslashes. It currently
- uses 'echo', and 'echo' isn't portable if its argument contains
- backslashes. Problem found on OpenBSD 3.4. Also, do not assume
- that the byte '\0xff' is not printable in the C locale; it is,
- under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
- not printable, so use '\0x81' to test.
-
- * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
- version of GCC, since the macro is used with non-GCC compilers.
-
- Fix core dump reported by Pablo De Napoli in
- <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
- * tests/regression.at (Invalid inputs with {}): New test.
- * src/parse-gram.y (token_name): Translate type before using
- it as an index.
-
- * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on

- ((__unused__)).
- (yyFail, yyMemoryExhausted, yyreportAmbiguity):
- Add __attribute__ ((__noreturn__)).
-
- * etc/clcommit: Remove. We weren't using it, and it failed
- "make maintainer-distcheck".
- * Makefile.maint: Merge from coreutils.
- (CVS_LIST, CVS_LIST_EXCEPT): New macros.
- (syntax-check-rules): Change list of rules as described below.

- (my-distcheck): Use more-modern GCC flags.
- (signatures, %.asc): Remove.
- (rel-files, announcement): Remove signatures.
- Restore old updating code, even though we don't use it, so
- that we're the same as coreutils.
- (alpha, beta, major): Depend on news-date-check.
- Make the upload commands.

- * src/main.c (main): Cast bindtextdomain and textdomain calls to
- void, to avoid warning when NLS is disabled.
- * src/output.c: Include scan-skel.h.
- (scan_skel): Remove decl, since scan-skel.h does this.
- (output_skeleton):
- Indent calls to "error" to pacify "make maintainer-distcheck".
- * src/print_graph.c: Don't include <obstack.h>, as system.h does this.

-
-2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
-
- * configure.ac: Update version number.
-
- * Makefile.am (SUBDIRS): Add examples; somehow this got removed
- accidentally.
- * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
- autogenerated by the maintainer.
- * examples/calc++/.cvsignore: Add *.yy.
-
- * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
- * lib/bitset_stats.c (bitset_stats_init): Likewise.
- * lib/bitsetv.c (bitsetv_alloc): Likewise.
-
- * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
-
- * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
- from maintainer-distcheck about casting the argument of 'free'.
-
- * NEWS: Mention recent yytname changes.
- * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
-
- * bootstrap: For translations that have not yet been upgraded to
- the new runtime-po domain, prime the pump by extracting the
- relevant strings from the obsolete translations. This code can be
- removed once the bison-runtime domain has been translated by each
- team.
-
- * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
- now that token names are already quoted.
-
- Fix problem reported by Anthony Heading.

-
-2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
- again if the first call fails.
-
- * data/glr.c (yytnamerr): New function.
- (yyreportSyntaxError): Use it to dequote most string literals.
- * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
- with other skeletons. All uses changed.
- (yytnameerr_): New function.
- (yyreport_syntax_error): Use it to dequote most string literals.

- (yyerrlab): Use it to decode most string literals.
- * doc/bison.texinfo (Decl Summary, Calling Convention):
- Clarify quoting convention of yytname.

- the 2005-04-17 change, which is now accomplished (mostly) via
- changes in the parsers as described above.
- * tests/regression.at (Token definitions, Web2c Actions):
- Undo most 2005-04-17 change here, too.
-
-2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
-
- Fix more problems reported by twlevo@xs4all.nl.
- * tests/cxx-type.at: Don't pipe output of ./types through sed to
- remove trailing spaces. This loses the exit status of ./types,
- and isn't needed since ./types shouldn't be emitting trailing
- spaces.
- * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
- as the stack isn't valid in that case.
-
- * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
- (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
- (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):

- Likewise.
-
- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
- overly-picky compilers that reject 'char *foo = "bar";'.
-
- * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
- to FILE * parameter, not to stderr. This fixes a typo introduced
- in the 2005-07-12 change.
-
- * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
- warnings from GCC 4.
-
- * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):

-
- Destructor cleanups and regularization among the three skeletons.
- * NEWS: Document the behavior changes.
- * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
- stack before failing, as the cleanup code will do it for us now.
- * data/lalr1.cc (yyerrlab): Likewise.
- * data/glr.c (yyparse): Pop everything off the stack before
- freeing it, so that destructors get called properly.
- * data/lalr1.cc (yyreturn): Likewise.
- * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
- This is more consistent.
- * doc/bison.texinfo (Destructor Decl): Mention more reasons
- why destructors might be called. 1.875 -> 2.1.
- (Destructor Decl, Decl Summary, Table of Symbols):
- Some English-language cleanups for %destructor.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
- Add output line for destructor of start symbol.
- * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
- because of that same extra output line.
-
- * NEWS: Document minor wording changes in diagnostics of
- Bison-generated parsers.
- * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
- Remove unused formals. All uses changed.
- (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
- (yyparse): Rename yyoverflowlab to yyexhaustedlab.
- * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
- Rename yyoverflowab to yyexhaustedlab.
- When memory exhaustion occurs during syntax-error reporting,
- report it separately rather than in a single diagnostic; this
- eases translation.
- * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
- (Memory Exhausted): Renamed from Parser Stack Overflow.
- Revamp wording slightly to prefer "memory exhaustion".
- * tests/actions.at: "parser stack overflow" -> "memory exhausted".
-
- * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
-
- Add i18n support to the GLR skeleton. Partially fix the C++
- skeleton; a C++ expert needs to finish this. Remove debugging
- msgids; there's little point to having them translated, since they
- can be understood only by someone who can read the
- (English-language) source code.
-
- Generate runtime-po/bison-runtime.pot automatically, so that we
- don't have to worry about garbage getting in that file. We'll
- make sure after the next official release that old msgids don't
- get lost. See
- <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
-
- * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
- Now auto-generated.
- * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
- Fix typos in explanations of the runtime file.
- * bootstrap: Change gettext keyword from YYI18N to YY_.
- Use standard Makefile.in.in in runtime-po, since we'll arrange
- for backward-compatible bison-runtime.po files in a different way.
- * data/glr.c (YY_): New macro, from yacc.c.
- (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
- Translate messages intended for users.
- (yyreportSyntaxError): Change "virtual memory" to "memory" to match
- the wording in the other skeletons. We don't know that the memory
- is virtual.
- * data/lalr1.cc (YY_): Renamed from _. All uses changed.
- Use same method that yacc.c uses.
- Don't translate debugging messages.
- (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
- it doesn't work (yet), and requires C++ expertise to fix.
- * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
- Move defn to a more logical place, to be consistent with other
- skeletons.
- Don't translate debugging messages.
- Don't assume line numbers fit in unsigned int; use unsigned long fmts.
- * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
- to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
- * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
-
- Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
- void, not int.
- * tests/glr-regression.at (Badly Collapsed GLR States):
- Likewise.
- (Improper handling of embedded actions and dollar(-N) in GLR parsers):
- yylex should return 0 at EOF rather than aborting.
-
- Improve tests for stack overflow in GLR parser.
- Problem reported by twlevo@xs4all.nl.
- * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
- All uses removed.
- (yyStackOverflow): Just longjmp, but with value 2 so that caller
- can handle the problem.
- (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
- (yyparse): New local variable yyresult to record the result.
- Use result of setjmp to set it, rather than storing itinto
- struct.
- (yyDone): Remove label.
- (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
- to mimic yacc.c. Do not discard lookahead if it's EOF (possible
- if YYABORT is used).
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
- yyparse status; put status > 1 into diagnostic.
- Check that status==2 works.
- * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
- Use exit status 3 for failure to open (which shouldn't happen).
-
-2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
-
- * tests/conflicts.at (%nonassoc and eof): Don't exit with status
- 1 on syntax error; just let yyparse do its thing.
- * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
- * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
- (Exploding the Stack Size with Alloca):
- (Exploding the Stack Size with Malloc):
- Expect exit status 2, not 1, since the parser is supposed to blow
- its stack. Problem reported by twlevo@xs4all.nl.
-
- * data/glr.c (yyparse): Don't assume that the initial calls
- to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
- Print a stack-overflow message and fail instead.
- Initialize the line-number information before creating the stack,
- so that the stack-overflow message can report line zero safely.
-
-2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
-
- Fix problems reported by twlevo@xs4all.nl.
- * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
- (yyuserMerge): Provide a default case if b4_mergers is empty.
- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
- * tests/glr-regression.at
- (Improper handling of embedded actions and dollar(-N) in GLR parsers):
- Add casts to pacify C++ compilers.
- * tests/glr-regression.at (Improper merging of GLR delayed action
- sets): Declare yylex before using it.
- * tests/Makefile.am (maintainer-check-g++): Fix a stray
- $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
- test for valgrind; valgrind is independent of g++.
- (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
- for compatibility with POSIX 1003.1-2001 (if running coreutils).
- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
- Use a destructor, so that we can expand the stack. Change
- YYSTYPE to char * so that we can free it. Cast result of malloc.
-
-2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
-
- * data/glr.c (yyuserAction): Fix uninitialized variable that caused

-
- * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:

- Put comment before action, since older 'make' can't handle comment
- in action.
- $(BUILT_SOURCES): List all built sources, not just some of them.
- $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
- $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.

-2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.c (yyFail): Drastically simplify; since the format argument
- never had any % directives, we can simply pass it to yyerror.

- be modified later, as that is the usual style in glr.c.
- Problems reported by Paul Hilfinger.
-
- Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
- and size overflow errors.
- * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
- in case the user prolog sets feature-test macros like _GNU_SOURCE.
- (YYSIZEMAX): New macro.
- (yystpcpy): New function, taken from yacc.c.
- (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
- (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
- so that we don't have to maintain their signatures.

- than vsprintf. Allocate a bigger buffer if possible.
- Report an error if buffer allocation fails.
- (yyStackOverflow): New function.
- (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
- the initialization was successful. It might fail if storage was
- exhausted.
- (yyexpandGLRStack): Add more checks for storage allocation failure.

- (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
- (yysplitStack, yyprocessOneStack, yyparse, yypstack):
- Don't assume stack number fits in int.
- (yysplitStack): Check for storage allocation failure.
- (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
- can print diagnostics on storage allocation failure. All callers
- changed.
- (yyresolveValue): Use yybool for boolean.
- (yyreportSyntaxError): Check for size-calculation overflow.
- This code is taken from yacc.c.
- (yyparse): Check for storage allocation errors when allocating

-

- (alloca): Include <stdlib.h> to get it, if it's not built in.
- (YYMALLOC, YYFREE): Define only if needed.
- (malloc, free): Declare, but only if needed, as this infringes on

- From Marcus Holland-Moritz.
- * data/yacc.c (yyerrlab): Move the code that destroys the stack
- from here....
- (yyreturn): to here. That way, destructors are called properly
- even if the stack overflows, or the user calls YYACCEPT or
- YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.

-
-2005-04-24 Paul Eggert <eggert@cs.ucla.edu>

-
-2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/parse-gram.y: Include quotearg.h.

- quotes it for us.
- * src/scan-gram.l: Include quotearg.h.
- ("\""): Omit quote.

- in token strings.
-

- make it easier to translate, and to avoid problems with arithmetic
- overflow. Change "virtual memory" to "memory" in diagnostic, since
- we don't know whether the memory is virtual.
-
-2005-04-13 Paul Eggert <eggert@cs.ucla.edu>

- (symbol_check_alias_consistency): Don't call symbol_type_set
- if the type name is already correct.

-
-2005-03-25 Paul Eggert <eggert@cs.ucla.edu>

- stdlib.h that uses the identifier c as a member of struct
- drand48_data. Problem reported by Horst Wente.
-
-2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
-
- * bootstrap: Change translation URL from

-2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
-
- * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options

-
-2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
-
- * tests/glr-regression.at (glr-regr2a.y): Try to dump core

- to widespread problems in unchecked stack-overflow detection.
- * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's

- Returning a bool introduces a problem: 0 corresponds to false, and

- the conventions for yyparse.
- Alternatively we could return void and send an exception.

-
- Remove uses of 'short int' and 'unsigned short int'. This raises
- some arbitrary limits. It uses more memory but nowadays that's
- not much of an issue.
-
- This change does not affect the generated parsers; that's a different
- task, as some users will want to conserve memory there.
-
- Ideally we should use size_t to represent all object counts, and
- something like ptrdiff_t to represent signed differences of object
- counts; but that will require more code-cleanup than I have the
- time to do right now.

- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
- that column numbers start at column 0, as per GNU Coding
- Standards, the others tests, and the doc.
- (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
- Adjust to the above change (first column is 0).
- And adjust the location of the "<error>", now covering the whole
- line.
-
-2004-10-22 Akim Demaille <akim@epita.fr>
- and Paul Eggert <eggert@cs.ucla.edu>
-
- Remove some arbitrary limits on goto numbers and relations.
- * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
- initial values, since they're never used.
- (set_goto_map): ngotos is now unsigned, so test for overflow
- by seeing whether it wraps around to zero.
- * src/lalr.h (goto_number): Now size_t, not short int.

-2004-10-11 Akim Demaille <akim@epita.fr>
-
- * src/symtab.c (symbol_check_alias_consistency): Also check

- Reported by Alexandre Duret-Lutz.
- Recode the handling of associativity and precedence in terms
- of symbol_precedence_set.
- Accept no redeclaration at all, not even equal to the previous
- value.
- (redeclaration): New.
- Use it to factor redeclaration complaints.
- (symbol_make_alias): Don't set the type of the alias, let

-
-2004-10-05 Akim Demaille <akim@epita.fr>
-
- In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
- whether the reducion was empty or not. This leaves room to
- improve the use of YYLLOC_DEFAULT in such a case.
- lalr1.cc is still experimental, so changing this is acceptable.
- And finally, there are probably not many users who changed the
- handling of locations in GLR, so changing is admissible too.
-
- * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
- empty reduction, set @$ to an empty location ending the previously
- stacked symbol.
- Adjust uses to make sure the code is triggered on empty
- reductions.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
- expected output: empty reductions have empty locations.
-
-2004-09-29 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc: Move towards a more standard C++ coding style
- for templates: Class < T > -> Class<T>.
-
-2004-09-29 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc: Reinstall the former ctor, for sake of
- compatibility, but warn it will be removed.

- type* var).
-
-2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/parse-gram.y (add_param): Rewrite to avoid strchr,

- Suggested by Paul Eggert.
-
-2004-09-20 Akim Demaille <akim@epita.fr>
-
- Let the initial-action act on the look-ahead, and use it for the
- "initial push" (corresponding to an hypothetical beginning-of-file).
- And let lalr1.cc honor %initial-action.
-
- * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
- example.
- * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
- (Parser::Parser): Remove the ctor that used to initialize it.

- Initialize the stacks with the lookahead.
- * data/yacc.c: Let $$ and @$ in %initial-action designate the
- look-ahead.

- (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
- When reducing on an empty RHS, use the latest stacked location as
- location.
- yylloc is not always available.

- Also, honor initial-actions.
-
-2004-09-20 Akim Demaille <akim@epita.fr>
-
- * data/yacc.c (YY_LOCATION_PRINT): New.
- Define when we know YYLTYPE's structure, i.e., when the default
- YYLLOC_DEFAULT is used.
- * data/c.m4 (b4_yysymprint_generate): Use it.
- * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
- value of the result.
- (error_start_): Replace with...
- (error_range_): this location array.
- This allows to replace code relying on the implementation of
- locations by portable code.
- * data/yacc.c (yylerrsp): Replace with...
- (yyerror_range): this.
- Every time a token is popped, update yyerror_range[0], to have an
- accurate location for the error token.
- * data/glr.c (YY_LOCATION_PRINT): New.
- (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
- deference a pointer.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer

-2004-09-16 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
- (iterator, const_iterator): these, to be more in the C++ spirit.
- Also, return reverse iterators so that when displaying the stack
- we display its bottom first.
- (Parser::stack_print_, Parser::reduce_print_): Match the messages
- from yacc.c.
- We should probably use vector here though.
-
-2004-09-16 Akim Demaille <akim@epita.fr>
-
- Have more complete shift traces.
-
- * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT

- including for the error token.
- * data/lalr1.cc (symprint_): Output the location.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
- output the location within the %printer.
- Activate GLR tests, at least to make sure they compile properly.
- They still don't pass though.
- * tests/calc.at: Adjust expect verbose output, since now "Entering
- state..." is on a different line than the "Shifting" message.
-
-2004-09-08 Akim Demaille <akim@epita.fr>
-
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
- Bison directive from the Bison file to the invocation of this
- macro, so that these directives are passed to
- AT_BISON_OPTION_PUSHDEFS to get correct help macros.
- Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
- Move the AT_SETUP/AT_CLEANUP outside, to report as test title
- the extra Bison directives instead of the whole series.
- Change the grammar so that there are recoverable errors, and
- unrecoverable errors. Now we can have the parser give up before
- consuming the whole input. As a result we now can observe that
- the lookahead is freed when needed.
- Change the parser source to parse argv[1] instead of a hard coded
- string.
- Simplify yylex, and give a value and location to EOF.
- Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
- passed directives already coded in the file.
- Add some tests to check the location of "error".
- For some tests, the C++ parser is correct, and not yacc.c.
- For other tests, they provide different, but unsatisfying, values,
- so keep the C++ value so that at least one parser is "correct"
- according to the test suite.
- (Actions after errors): Remove, this is subsumed by the
- AT_CHECK_PRINTER_AND_DESTRUCTOR series.
-
-2004-09-06 Akim Demaille <akim@epita.fr>

- argument, an informative message.
- Call YY_SYMBOL_PRINT.
- Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
- * data/lalr1.cc (destruct_): Likewise.
- In addition, no longer depend on b4_yysymprint_generate and
- b4_yydestruct_generate to generate these functions, do it "by
- hand".
-
-2004-09-03 Akim Demaille <akim@epita.fr>
-
- * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
- invoked, yydestruct the lookahead.
- * tests/calc.at (Calculator $1): Update the expected lengths of

- one.
-
-2004-09-02 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc (b4_yysymprint_generate): New.
- (symprint_): New member function, defined when YYDEBUG.
- Use it consistently instead of token/nterm debugging output by
- hand.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
- %printer calls to use cdebug_ when using lalr1.cc.
-
-2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
-
- * data/glr.c: Guard the declarations of yypstack and yypdumpstack

-
-2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
-
- Adjust to latest gnulib.
- * bootstrap (gnulib_modules): Add xalloc-die.
- Set LC_ALL=C so that file names sort consistently.
- Prefer the gnulib copies of gettext.m4, glibc21.m4,
- inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
- uintmax_t.m4, ulonglong.m4.
- (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
- po.m4 since we are now using _gl.m4 instead.
-
-2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>

- UNION-FLAG. All callers changed.
- (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
- Use type char, not unsigned int, when declaring an array of char;

-
-2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
-
- * doc/bison.texinfo: Minor editorial changes, mostly to the new

- * tests/calc.at, tests/actions.at: Workaround for SGI
- C++ compiler. (trivial change)
-
-2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
-
- Spent a few hours checking out which prerequisite versions the
- current sources actually require. I went all the way back to
- Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
- a seemingly endless set of combinations of versions more recent
- than that. The bottom line is that the current sources require
- fairly recent versions of the build tools, and it'll be some work
- to change this.
- * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
- (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.

-
- * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
- (it fails with a Autoconf-without-aclocal-m4 diagnostic).
-
-2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
-
- * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
- 0.11.5. Suggested by Bruno Haible.

- put into the -d output file, and mention what to do if YYSTYPE is
- defined as a macro.
-
-2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
-
- Undo change made earlier today: it caused autopoint to not bring
- in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
- autopoint's.
-
- * bootstrap: Check that gettext version matches what's in
- configure.ac. Warn users to ignore robots.txt ERROR 404.
- * bootstrap: Undo today's earlier change (logged below).
- * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
-
- The gettext version checking is causing more trouble than it's
- curing; remove it. Problem reported by Paul Hilfinger.
-
- * bootstrap: Issue a warning that one can expect a message
- 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
- * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
-
-2004-05-23 Paul Eggert <eggert@cs.ucla.edu>

- for us.
-
- * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".

- with latest obstack.h.
- * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args

-
- * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
- so that this include file can stand alone.

- does this now. Include subpipe.h first after config.h, to
- test whether it can stand alone.

-
-2004-02-25 Paul Eggert <eggert@twinsun.com>
-
- * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from

-
-2004-02-02 Paul Eggert <eggert@twinsun.com>
-
- * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
- $(top_srcdir)/lib and ../lib. This fixes a bug reported

-2003-08-25 Akim Demaille <akim@epita.fr>
-
- When reducing initial empty rules, Bison parser read an initial
- location that is not defined. This results in garbage, and that
- affects Bison's own parser. Therefore we need (i) to extend Bison
- to support a means to initialize this location, and (ii) to use
- this CVS Bison to fix CVS Bison's parser.
-
- * src/reader.h, reader.c (epilogue_augment): Remove, replace
- with...
- * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
- * src/parse-gram.y: Adjust.

- (%error-verbose): Since we require CVS Bison, there is no reason
- not to use it.
- * src/scan-gram.l: Adjust.
- * src/Makefile.am (YACC): New, to make sure we use our own parser.
- * data/yacc.c (yyparse): Use b4_initial_action.

- Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
- error recovery loops. This patch is based on
- <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
- Also, augment the similarity between lalr1.cc and yacc.c.
- Note: the locations of error recovery rules are not correct yet.
-
- * data/lalr1.cc: Comment changes to augment the similarity between
- lalr1.cc and yacc.c.
- (YYERROR): Goto to yyerrorlab, not yyerrlab1.
- (yyerrlab1): Remove, but where it used to be (now the bottom part of
- yyerrlab), when hitting EOF, pop the whole stack here instead of
- merely falling thru the default error handling mechanism.
- (yyerrorlab): New label, with the old contents of YYERROR,
- plus the following change: pop the stack of rhs corresponding
- to the production that invoked YYERROR. That is how Yacc
- behaves (required by POSIX).
- * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
- fail.
-
-2003-08-25 Akim Demaille <akim@epita.fr>
-
- Tune local.at so that people can "autom4te -l autotest calc.at -o
- calc" for instance, to extract a sub test suite.
-
- * tests/testsuite.at: Move the initialization, Autotest version
- requirement, and AT_TESTED invocation into...
- * tests/local.at: here.
- * tests/testsuite.at: Include it for compatibility with Autoconf
- 2.57.

- and $-N in GLR parsers): Remove unused local variable from yylex.
- * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take

- Bison. Pacify GCC by using parameter.
-
-2003-06-02 Paul Eggert <eggert@twinsun.com>
-
- * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
- yy::Location::lines, yy::Location::columns): Rename arguments
- to avoid shadowing; this removes a warning generated by GCC 3.3.
-
-2003-06-01 Paul Eggert <eggert@twinsun.com>
-
- Don't pass C-only warning optins (e.g., -Wmissing-declarations)

-
- Fix a GLR parser bug I reported in February; see
- <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
- The problem was that GLR parsers did not conform to the C standard,
- because actions like { $1 = $2 + $3; } expanded to expressions
- that invoked YYFILL in separate subexpressions, and YYFILL assigned
- to a local variable. The C standard says that expressions
- like (var = f ()) + (var = f ()) have undefined behavior.
- Another problem was that GCC sometimes issues warnings that
- yyfill and its parameters are unused.
-
- * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
- as possibly unused.
- (yyfill): New function.
- (YYFILL): Use it.
- (yyuserAction): Change type of yynormal to bool, so that it matches
- the new yyfill signature. Mark it as possibly unused.
-
-
- Follow up on a bug I reported in February, where a Bison-generated
- parser can loop. Provide a test case and a fix for yacc.c. I
- don't have a fix for lalr1.cc or for glr.c, unfortunately.
- The original bug report is in:
- <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
-
- * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
- macro's size was becoming unwieldy.
- (yyerrlab): Do not discard an empty lookahead symbol, as this
- might destroy garbage.
- (yyerrorlab): New label, with the old contents of YYERROR,
- plus the following change: pop the stack of rhs corresponding
- to the production that invoked YYERROR. That is how Yacc
- behaves, and POSIX requires this behavior.
- (yyerrlab1): Use YYPOPSTACK instead of its definiens.
- * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
- Define 'alarm' to do nothing if unistd.h is not available.
- Add a new rule "exp: '-' error;" to test the above change to
- data/yacc.c. Use 'alarm' to abort any test taking longer than
- 10 seconds, as it's probably looping.
- (AT_CHECK_CALC): Test recovery from error in new grammar rule.
- Also, the new yacc.c generates two fewer diagnostics for an
- existing test.
-
-2003-05-24 Paul Eggert <eggert@twinsun.com>
-
- * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
- YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.

- -ansi -Wall -gall).

-2003-05-12 Paul Eggert <eggert@twinsun.com>
-
- * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the

-
-2003-05-05 Paul Eggert <eggert@twinsun.com>
-
- * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes

-
- * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
- Declare to be of type suitable for the ninf value itself, not of

-
- * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
- invokes it. We shouldn't invoke it twice because it will attempt

-
- * src/scan-gram.l: Add %option nounput, since we no longer use unput.
- (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
- Do not insert the expected token via unput, as this runs afoul
- of a POSIX-compatibility bug in flex 2.5.31.
- All uses changed to BEGIN the parent state,
- since we no longer insert the expected token via unput.
- * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
- that is no longer emitted after the above change.
-
- * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
- the first one. This change is from Paul Hilfinger, and it fixes
- regression reported by Werner Lemberg in

-
- (resolve_sr_conflict): Don't invoke state_errs_set

-
- * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
- (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
- cursor, instead of leaving it undefined. This fixes a bug
- reported by Tim Van Holder in
- <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
- * tests/input.at (Torturing the Scanner): Test the scanner on
- an empty input file, which was Tim Van Holder's test case.
-
- * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
- <sys/resource.h> can be included, include sys/time.h and
- sys/times.h first, if available. This works around the SunOS
- 4.1.4 porting bug reported by Bruce Becker in
- <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
-
- * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
- AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
- AC_HEADER_SYS_WAIT.
-
- Merge changes from gnulib. This was prompted because the CVS
- snapshot didn't build on Solaris 7 due to strnlen problems.
-
- These changes need to be merged back into gnulib:
- * lib/hash.c: Include <stdbool.h> unconditionally.
- * m4/onceonly.m4 (m4_quote): New macro.
- (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):

-
-2003-03-01 Paul Eggert <eggert@twinsun.com>
-
- * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
- not loc->end, since loc->end might contain garbage and this leads
- to undefined behavior on some platforms.
- (id_loc, token_start): Use (IF_LINTed) initial values that do not
- depend on *loc, so that the reader doesn't give the the false
- impression that *loc is initialized.
- (<INITIAL>"%%"): Do not bother setting code_start, since its value
- does not survive the return.
-
-2003-03-01 Akim Demaille <akim@epita.fr>
-
- * src/scan-gram.l (code_start): Always initialize it when entering
- into yylex, as SC_EPILOGUE is activated *before* the corresponding
- yylex invocation. An alternative would be making it static, but
- then it starts with the second %%'s beginning, instead of its end.
-
-2003-02-28 Paul Eggert <eggert@twinsun.com>
-
- * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
- around a UnixWare 7.1.1 porting bug reported by John Hughes in
- <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
-

- Suggested by Paul Eggert.
-
-2003-02-20 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc (position.hh): Make sure "columns" never pushes
- before initial_columns.
- (location.hh): Use consistent variable names when defining the
- operator<<.
- Use "last" so that we subtract from Positions, not from unsigned.
-
-2003-02-20 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc (position.hh): New subfile, including the extended
- and Doxygen'ed documentation of class Position.

- AT_YACC_IF.
- Redefine AT_YYERROR_SEES_LOC_IF using it.
- (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
- not defined.
- Don't use the location in yy::Parser::error_ and

- error recovery, mixing with/without pops and discarding of the
- lookahead.
- Exercise YYERROR.
- Disable the lalr1.cc tests as currently it doesn't support YYERROR.
-
-2003-02-17 Paul Eggert <eggert@twinsun.com>
-
- * tests/atlocal.in (LDFLAGS, LIBS): New vars.
- * tests/testsuite.at (AT_COMPILE): Use them.
- This fixes the testsuite problem reported by Robert Lentz in
- <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
-
-2003-02-12 Paul Eggert <eggert@twinsun.com>
-
- * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:

-
- * src/scan-skel.l: Scan more than one inert character per yylex

-
- * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
-
-2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
-
- * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
- of $1.
-
- Changes in response to error report by S. Eken: GLR mode does not
- handle negative $ indices or $ indices in embedded rules correctly.
- See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
-
- * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
- (b4_rhs_location): Ditto.
- (yyfill): New function to copy from stack tree into array

-2003-01-28 Paul Eggert <eggert@twinsun.com>
-

- and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
-
-2003-01-21 Paul Eggert <eggert@twinsun.com>
-
- * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
- we don't need to worry about yyerrlab1 being reported as an
- "unused label" by non-GCC C compilers. The downside is that if
- locations are used then a couple of statements are duplicated each
- time YYERROR is invoked, but the upside is that the warnings
- should vanish.
- (yyerrlab1): Move code to YERROR.
- (yyerrlab2): Remove. Change uses back to yyerrlab1.
- This reverts some of the 2002-12-27 change.
-
-2003-01-17 Paul Eggert <eggert@twinsun.com>
-
- * src/output.c (symbol_printers_output): Fix typo that led

- Quoc Peyrot <chojin@lrde.epita.fr>,
- Robert Anisko <anisko_r@lrde.epita.fr>
-
- * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
- when the stacks contain one element, as the loop would otherwise
- free the last state, and then use the top state (the one we just
- popped). This means that the initial elements will not be freed
- explicitly, as is the case in yacc.c; it is not a problem, as
- these elements have fake values.
-
-2003-01-11 Paul Eggert <eggert@twinsun.com>
-
- * NEWS: %expect-violations are now just warnings, reverting
- to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
- bootstrapping problem reported by Matthias Klose; see

- * src/conflicts.c (conflicts_print): Likewise.
- * tests/conflicts.at (%expect not enough, %expect too much,

-
- * Makefile.maint (WGETFLAGS):

- (EXTRA_SCRIPTS): New var, for yacc.
-
- * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
- since GNU C++ (as of 3.2.1) does not allow attributes on labels.
- Problem reported by Nelson H. F. Beebe.
-
-2003-01-03 Paul Eggert <eggert@twinsun.com>
-
- * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
- (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
- when compiling Bison 1.875's `bitset bset = obstack_alloc
- (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
-
- * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
- ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
- grow to a huge size with typical invocation.
-
- * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
- Use the pattern recommended by Autoconf 2.57, except also protect
- against double-definition.
- * src/system.h: Likewise.
- Portability issues reported by Nelson H. F. Beebe.
-
- * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
- All uses changed. Provide a definition in both C and C++.

- * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
- Reported by Nelson H. F. Beebe.

-
-2002-12-30 Paul Eggert <eggert@twinsun.com>
-
- * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
- Moved here from...
- (<INITIAL>","): Here. This causes stray "," to be treated
- more uniformly.
-
- * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
- last brace in braced code when not in Yacc mode, for compatibility
- with Bison 1.35. This resurrects the 2001-12-15 patch to
- src/reader.c.
-
- * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
- yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
-
-2002-12-28 Paul Eggert <eggert@twinsun.com>
-
- * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
- that of SYM's type. This fixes Debian bug 168069, reported by
- Thomas Olsson.
-
-2002-12-28 Paul Eggert <eggert@twinsun.com>
-
- Version 1.75f.
-
- Switch back to the Yacc style of conflict reports, undoing some
- of the 2002-07-30 change.
- * doc/bison.texinfo (Understanding): Use Yacc style for
- conflict reports. Also, use new way of locating rules.
- * src/conflicts.c (conflict_report):
- Renamed from conflict_report_yacc, removing the old
- 'conflict_report'. Translate the entire conflict report at once,
- so that we don't assume that "," has the same interpretation in
- all languages.
- (conflicts_output): Use Yacc-style conflict report for each state,
- instead of our more-complicated style.
- (conflicts_print): Use Yacc-style conflict report, except print
- the input file name when not emulating Yacc.
- * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
- Conflicted Reduction, %expect not enough, %expect too much,
- %expect with reduce conflicts): Switch to Yacc-style conflict reports.
- * tests/existing.at (GNU Cim Grammar): Likewise.
- * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
-
- * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
- fatal): Don't invoke fflush; it's not needed and it might even be
- harmful for stdout, as stdout might not be open.
- * src/reduce.c (reduce_print): Likewise.

-
- Fix a bug where error locations were not being recorded correctly.
- This problem was originally reported by Paul Hilfinger in
- <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
-
- * data/yacc.c (yyparse): New local var yylerrsp, to record the
- top of the location stack's error locations.
- (yyerrlab): Set it. When discarding a token, push its location
- onto yylerrsp so that we don't lose track of the error's end.
- (yyerrlab1): Now is only the target of YYERROR, so that we can
- properly record the location of the action that failed. For GCC
- 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
- GCC warning about yyerrlab1 being unused if YYERROR is unused.
- (yyerrlab2): New label, which yyerrlab now falls through to.
- Compute the error's location by applying YYLLOC_DEFAULT to
- the locations of all the symbols that went into the error.
- * doc/bison.texinfo (Location Default Action): Mention that
- YYLLOC_DEFAULT is also invoked for syntax errors.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
- Error locations include the locations of all the tokens that were
- discarded, not just the last token.
-
-2002-12-26 Paul Eggert <eggert@twinsun.com>
-
- * src/files.c: Include quote.h.
- (compute_output_file_names): Warn if we detect conflicting
- outputs to the same file. This should catch the misunderstanding
- exemplified by Debian Bug 165349, reported by Bruce Stephens..
-
- * src/conflicts.c (conflicts_print): If the user specifies
- "%expect N", report an error if there are any reduce/reduce
- conflicts. This is what the manual says should happen.
- This fixes Debian bug 130890, reported by Anthony DeRobertis.
- * tests/conflicts.at (%expect with reduce conflicts): New test.
-
- Don't use m4_include on relative file names, as it doesn't work as
- desired if there happens to be a file with that name under ".".
-
- * m4sugar/version.m4: Remove; it was included but it wasn't used.
- * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
- * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
- * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
- * src/output.c (output_skeleton): Use full path names when
- specifying a file to include; don't rely on include path, as
- it's unreliable when the working file contains a file with
- that name.
-

- * data/glr.c: Comment fix.
- * doc/bison.1: Remove references. Also, mention "yacc".
-
- * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
- with -g option.
-
- * src/parse-gram.y (declaration): Use enum "report_states" rather
- than its numeric value 1.
-
- * src/scan-skel.l ("@output ".*\n): Close any old yyout before
- opening a new one. This fixes Debian bug 165349, reported by
- Bruce Stephens.
-
-2002-12-24 Paul Eggert <eggert@twinsun.com>
-
- Version 1.75e.
-
- * Makefile.maint (cvs-update): Don't assume that the shell
- supports $(...), as Solaris sh doesn't.
-
- * src/parse-gram.y (lloc_default): Remove test for empty
- nonterminals at the end, since it didn't change the result.
-
-2002-12-24 Paul Eggert <eggert@twinsun.com>
-
- If the user does not define YYSTYPE as a macro, Bison now declares it
- using typedef instead of defining it as a macro. POSIX requires this.
- For consistency, YYLTYPE is also declared instead of defined.
-
- %union directives can now have a tag before the `{', e.g., the
- directive `%union foo {...}' now generates the C code
- `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
- The default union tag is `YYSTYPE', for compatibility with Solaris 9
- Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
- instead of `yyltype'.
-
- `yystype' and `yyltype' are now obsolescent macros instead of being
- typedefs or tags; they are no longer documented and will be
- withdrawn in a future release.
-
- * data/glr.c (b4_location_type): Remove.
- (YYSTYPE): Renamed from yystype.
- (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
- (struct YYLTYPE): Renamed from struct yyltype.
- (YYLTYPE): Renamed from yyltype.
- (yyltype, yystype): New (and obsolescent) macros,
- for backward compatibility.
- * data/yacc.c: Likewise.
-
- * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
- does not specify a union tag. This is for compatibility with
- Solaris 9 yacc.
-
- * src/parse-gram.y (add_param): 2nd arg is now char * not char
- const *, since it is now modified by stripping surrounding { }.
- (current_braced_code): Remove.
- (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
- PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
- trailing " {...}". Now of type <chars>.
- (grammar_declaration): Adjust to bundled tokens.
- (code_content): Remove; stripping is now done by add_param.
- (print_token_value): Print contents of bundled tokens.
- (token_name): New function.
-
- * src/reader.h (braced_code, current_braced_code): Remove.
- (token_name): New decl.
-
- * src/scan-gram.l (handle_dollar, handle_at): Now takes int
- token_type, not braced_code code_kind. All uses changed.
- (SC_PRE_CODE): New state, for scanning after a keyword that
- has (or usually has) an immediately-following braced code.
- (token_type): New local var, to keep track of which token type
- to return when scanning braced code.
- (<INITIAL>"%destructor", <INITIAL>"%lex-param",
- <INITIAL>"%parse-param", <INITIAL>"%printer",
- <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
- instead of returning a token type immediately.
- (<INITIAL>"{"): Set token type.
- (<SC_BRACED_CODE>"}"): Use it.
- (handle_action_dollar, handle_action_at): Now returns bool
- indicating success. Fail if ! current_rule; this prevents a core dump.
- (handle_symbol_code_dollar, handle_symbol_code_at):
- Remove; merge body into caller.
- (handle_dollar, handle_at): Complain in invalid contexts.
-
- * NEWS, doc/bison.texinfo: Document the above.
- * NEWS: Fix years and program names in copyright notice.
-
-2002-12-17 Paul Eggert <eggert@twinsun.com>
-
- * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
- Reporting, Table of Symbols): Omit mentions of %lex-param and

-2002-12-15 Paul Eggert <eggert@twinsun.com>
-
- Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
- GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
- lookahead symbol, and which sets yychar in parser actions) and it
- disagreed with the Bison documentation. Bug
- reported by Andrew Walrond.
-
- * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
- as the caller now does that.
- (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
- (YYEMPTY): Parenthesize right hand side, since others use it.
- (yyparse): Don't assume that our generated code is the only code
- that sets yychar.

-
- * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do

-
- * tests/input.at (Torturing the Scanner): Surround the

-
- Revamp to fix many (but not all) of the C- and M4-related quoting
- problems. Among other things, this fixes the Bison bug reported
- by Jan Hubicka when processing the Bash grammar; see:
- <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
-
- Use new @ escapes consistently. Represent brackets with @{ and @}
- rather than @<:@ and @:>@, since this works a bit better with dumb
- editors like vi. Represent @ with @@, since @ is now consistently
- an escape. Use @oline@ and @ofile@ rather than __oline__ and
- __ofile__, to avoid unexpected expansions. Similarly, use @output
- rather than #output.
-
- * data/c.m4 (b4_copyright): Omit file name from comment, since
- the file name could contain "*/".
- (b4_synclines_flag): Don't quote the 2nd argument; it should already
- be quoted. All uses changed.
-
- * data/glr.c: Use new @ escapes consistently.
- (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
- b4_output_header_suffix, b4_output_header_name, b4_header_guard):

- * data/yacc.c: Likewise.
-
- * src/files.c (output_infix): Remove; all uses removed.
- * src/files.h: Likewise.

- mishandled funny characters in file names, and anyway it isn't
- needed any more.
- * data/yacc.c: Likewise.
- * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
-
- * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
- * data/yacc.c: Likewise.
-
- * src/muscle_tab.c: Include quotearg.h, since we need to quote C
- strings now.

- * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
- (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
- * src/output.c (escaped_file_name_output): New function.
- (prepare_symbols): Quote tokens for M4.
- (prepare): Don't insert output_infix, output_prefix,
- output_parser_name, output_header_name; this is now down by scan-skel.
- Insert skeleton as a C string.
-
- * src/output.c (user_actions_output, symbol_destructors_output,
- symbol_printers_output): Quote filenames for C and M4.
- * src/reader.c (prologue_augment, epilogue_set): Likewise.
-

- (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
- SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.

-
- * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
- them with auto vars.
- Switch to new escape scheme, where @ is the escape character uniformly.
- Abort if a stray escape character is found. Avoid unbounded input
- buffer when parsing non-escaped text.
-
- * tests/input.at (Torturing the Scanner): Add tests that @oline@,
- __oline__, #output, $@, and @{ do not have unintended meanings.
-
-2002-11-09 Paul Eggert <eggert@twinsun.com>
-
- Fix the test failure due to GCC warnings described in

- evaluate to 0 if it's impossible for NINF to be in the respective
- table.
- (yygetLRActions, yyrecoverParseError): Use them.
-
- * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
- counted in the token inserted at end of file. Now takes
- location_t *, not location_t, so that the location can be
- adjusted. All uses changed.
-

- diagnostic to match the new behavior.

- * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
- AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
- AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
- abort ();'. This reduces the runtime of the "Many lookaheads"
- test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
- GCC 3.2.
-
-2002-11-07 Paul Eggert <eggert@twinsun.com>
-
- * src/parse-gram.y (CHARACTER): Remove unused token.
- All uses removed.
-
- * src/scan-gram.l: Remove stack option. We no longer use the
- stack, since the stack was never deeper than 1; instead, use the
- new auto var c_context to record the stacked value.
-
- Remove nounput option. At an unexpected end of file, we now unput
- the minimal input necessary to end cleanly; this simplifies the
- code.
-
- Avoid unbounded token sizes where this is easy.
-
- (unexpected_end_of_file): New function.
- Use it to systematize the error message on unexpected EOF.
- (last-string): Now auto, not static.
- (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
- (scanner_last_string_free): Remove; not used.
- (percent_percent_count): Move decl to just before use.

- not the (never otherwised-used) CHARACTER.

-
-2002-11-05 Akim Demaille <akim@epita.fr>
-

- whole directive, not just that `invalid character: %'.
-
-2002-11-04 Akim Demaille <akim@epita.fr>
-
- * Makefile.maint: Update from Autoconf.

-
-2002-10-24 Akim Demaille <akim@epita.fr>
-

- http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html

-
- * src/getargs.c (getargs): When there are too few operands, report

-
- Let nondeterministic skeletons be usable with deterministic
- tables.
-
- With the patch, GAWK compiled by GCC without -O2 passes its test
- suite using a GLR parser driven by LALR tables. It fails with -O2
- because `struct stat' gives two different answers on my machine:
- 88 (definition of an auto var) and later 96 (memset on this var).
- Hence the stack is badly corrumpted. The headers inclusion is to
- blame: if I move the awk.h inclusion before GLR's system header
- inclusion, the two struct stat have the same size.
-
- * src/tables.c (pack_table): Always create conflict_table.

- not satisfying as we could compare an YYACTION computed from

-2002-02-14 Paul Eggert <eggert@twinsun.com>
-
- Remove the support for C++ namespace cleanliness; it was

- properly on some nonstandard C++ compilers. This can wait

- BISON_HAIRY.

- action member.
- Adjust callers.
- (output_skeleton): Don't look for the skeleton location, let m4 do
- that.
- Create `/tmp/muscles.m4'. This is temporary, a proper temporary
- file will be used.

- which have no values.
-
-2002-02-05 Akim Demaille <akim@epita.fr>
-
- * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
- * data/: here.
-
-2002-01-29 Paul Eggert <eggert@twinsun.com>
-
- * src/bison.simple (YYSIZE_T): Do not define merely because
- YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
- On some platforms, <alloca.h> does not declare YYSTD (size_t).
-
-2002-01-27 Akim Demaille <akim@epita.fr>
-
- Fix `%nonassoc and eof'.
-
- * src/state.c (errs_dup): Aaaah! The failure was due to bytes

- with
- memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
- !!!
- * tests/regression.at (%nonassoc and eof): Adjust to newest
- Autotest: `.' is not in the PATH.
-
-2002-01-27 Akim Demaille <akim@epita.fr>
-
- * tests/sets.at (AT_EXTRACT_SETS): New.
- (Nullable): Use it.
- (Firsts): New.
-
-2002-01-26 Akim Demaille <akim@epita.fr>
-
- * tests/actions.at, tests/calc.at, tests/headers.at,
- * tests/torture.at: Adjust to the newest Autotest which no longer
- forces `.' in the PATH.
-
-2002-01-25 Akim Demaille <akim@epita.fr>
-
- * tests/regression.at (%nonassoc and eof): New.
- Suggested by Robert Anisko.
-
-2002-01-24 Akim Demaille <akim@epita.fr>

-
- * src/system.h: Need to define __attribute__ away for non-GCC
- compilers as well (i.e., the vendor C compiler).
- Suggested by Albert Chin-A-Young.
-
-2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
-
- * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
- canonical definition.
- * src/system.h: Use the canonical definition for PARAMS (avoids
- a conflict with the macro from lib/hash.h).
-
-2002-01-11 Akim Demaille <akim@epita.fr>
-
- * configure.in: Use AC_FUNC_STRNLEN.

- (get_extension_index): Remove, unused.
-
-2002-01-08 Akim Demaille <akim@epita.fr>
-
- * src/getargs.c (AS_FILE_NAME): New.
- (getargs): Use it to convert DOSish file names.
- * src/files.c (base_name): Rename as full_base_name to avoid
- clashes with `base_name ()'.
- (filename_split): New.
- (compute_base_names): N-th rewrite, using filename_split.
-
-2002-01-08 Akim Demaille <akim@epita.fr>

- * src/Makefile.am: Add parse-skel.c and scan-skel.c to
- BUILT_SOURCES, to ensure they are generated first.
- * src/parse-skel.y: Use YYERROR_VERBOSE instead of
- %error-verbose to allow bootstrapping with bison 1.30x.
-
-2002-01-06 Akim Demaille <akim@epita.fr>
-
- * src/reader.c (parse_braces): Don't fetch the next char, the
- convention is to fetch on entry.
- * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
- 'switch' without a following semicolon.
- * tests/regression.at (braces parsing): New.
-
-2002-01-06 Akim Demaille <akim@epita.fr>
-
- Bison is dead wrong in its RR conflict reports.
-
- * tests/torture.at (GNU Cim Grammar): New.
- * src/conflicts.c (count_rr_conflicts): Fix.
-
-2002-01-06 Akim Demaille <akim@epita.fr>
-
- Creating package.m4 from configure.ac causes too many problems.
-
- * tests/Makefile.am (package.m4): Create it by hand,

-
-2002-01-06 Akim Demaille <akim@epita.fr>
-

-
-2002-01-03 Akim Demaille <akim@epita.fr>
-
- * src/parse-skel.y (process_skeleton): Don't bind the parser's

- args.
-
-2002-01-03 Akim Demaille <akim@epita.fr>
-
- * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
- The ISO C++ standard is extremely clear about it: stderr is
- considered a macro, not a regular symbol (see table 94 `Header
- <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
- Therefore std:: does not apply to it. It still does with fprintf.
- Also, s/cstdio.h/cstdio/.
-
-2002-01-03 Akim Demaille <akim@epita.fr>
-
- * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
- for non system headers.
-
-2002-01-02 Akim Demaille <akim@epita.fr>
-
- Equip the skeleton chain with location tracking, runtime trace,
- pure parser and scanner.
-
- * src/parse-skel.y: Request a pure parser, locations, and prefix
- renaming.
- (%union): Having several members with the same type does not help
- type mismatches, simplify.
- (YYPRINT, yyprint): New.
- (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
- (skel_error): this.
- Handle locations.
- * src/scan-skel.l: Adjust to these changes.
- * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
- (LOCATION_PRINT, skel_control_t): New.
-
-2001-12-30 Akim Demaille <akim@epita.fr>
-
- * src/parse-skel.y: Get rid of the shift/reduce conflict:
- replace `gb' with BLANKS.
- * src/scan-skel.l: Adjust.
-
-2001-12-30 Akim Demaille <akim@epita.fr>
-
- * src/system.h: We don't need nor want bcopy.
- Throw away MS-DOS crap: we don't need getpid.
- * configure.in: We don't need strndup. It was even causing
- problems: because Flex includes the headers *before* us,
- _GNU_SOURCE is not defined by config.h, and therefore strndup was
- not visible.
- * lib/xstrndup.c: New.
- * src/scan-skel.l: Use it.
- Be sure to initialize yylval.muscle member when scanning a MUSCLE.
- * src/parse-skel.y: Use %directives instead of #defines.
-
-2001-12-30 Akim Demaille <akim@epita.fr>
-
- * src/skeleton.h: New.
- * src/output.c (output_parser, output_master_parser): Remove, dead
- code.
- * src/output.h (get_lines_number, actions_output, guards_output)
- (token_definitions_output): Prototype them.
- * src/parse-skel.y: Add the license notice.
- Include output.h and skeleton.h.
- (process_skeleton): Returns void, and takes a single parameter.
- * src/scan-skel.l: Add the license notice.
- Include skeleton.h.
- Don't use %option yylineno: it seems that then Flex imagines
- REJECT has been used, and therefore it won't reallocate its
- buffers (which makes no other sense to me than a bug). It results
- in warnings for `unused: yy_flex_realloc'.
-
-2001-12-30 Robert Anisko <robert.anisko@epita.fr>
-
- * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
- (MUSCLE_INSERT_PREFIX): ...to there.
- * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
- (MUSCLE_INSERT_PREFIX): Move from here...
-
- * src/bison.hairy: Add a section directive. Put braces around muscle
- names. This parser skeleton is still broken, but Bison should not

- names.
-
- * src/files.h (strsuffix, stringappend): Add declarations.
- (tab_extension): Add declaration.

- names.
- (short_base_name): No longer static.
-
- * src/output.c (output_skeleton): New.
- (output): Disable call to output_master_parser, and give a try to
- a new skeleton handling system.
- (guards_output, actions_output): No longer static.
- (token_definitions_output, get_lines_number): No longer static.
-
- * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
-
- * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
- parse-skel.y.
-
- * src/parse-skel.y: New file.
- * src/scan-skel.l: New file.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- %name-prefix is broken.
-
- * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
- Adjust all dependencies.
- * tests/headers.at (export YYLTYPE): Strengthen this test: use
- %name-prefix.
-
- Renaming yylval but not yylloc is not consistent. Now we do.
-
- * src/bison.simple: Prefix yylloc if used.
- * doc/bison.texinfo (Decl Summary): Document that.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * doc/bison.texinfo: Promote `%long-directive' over

- Remove all references to fixed-output-files, yacc is enough.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
- user prologue. These are defaults.
- * tests/actions.at (Mid-rule actions): Make sure the user can
- define YYDEBUG and YYERROR_VERBOSE.
-
-2001-12-29 Akim Demaille <akim@epita.fr>

-2001-12-29 Akim Demaille <akim@epita.fr>

-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/reader.c (readgram): Don't add the rule 0 if there were no

-
-2001-12-29 Akim Demaille <akim@epita.fr>

-
- Fix the `GAWK Grammar' failure.

-
- * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
- cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
- Sparc, as they were causing more porting problems than the
- (minor) performance improvement was worth.
-
- Also, catch up with 1.31's YYSTD.
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-
- * src/output.c (output_gram): Rely on nritems, not the
- 0-sentinel. See below.
- Use -1 as separator, not 0.
- * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
- Rely on -1 as separator in yyrhs, instead of 0.
- * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
- twice `Now at end of input', therefore there are two lines less to
- expect.

- (insert_accepting_state, augment_automaton): Remove, since now
- these states are automatically computed from the initial state.
- (generate_states): Adjust.
- * src/print.c: When reporting a rule number to the user, substract
- 1, so that the axiom rule is rule 0, and the first user rule is 1.
- * src/reduce.c: Likewise.
- * src/print_graph.c (print_core): For the time being, just as for
- the report, depend upon --trace-flags to dump the full set of
- items.
- * src/reader.c (readgram): Once the grammar read, insert the rule
- 0: `$axiom: START-SYMBOL $'.
- * tests/set.at: Adjust: rule 0 is now displayed, and since the
- number of the states has changed (the final state is no longer
- necessarily the last), catch up.
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-
- Try to make the use of the eoftoken valid. Given that its value
- is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
- is used instead of > 0 where appropriate, (ii), depend upon nritems
- instead of the 0-sentinel.
-
- * src/gram.h, src/gram.c (nritems): New.
- Expected to be duplication of nitems, but for the time being...
- * src/reader.c (packgram): Assert nritems and nitems are equal.

- reductions, then output the report anyway if requested, then die.
- * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
- * src/reader.c (eoftoken): New.
- (parse_token_decl): If the token being defined has value `0', it
- is the eoftoken.
- (packsymbols): No longer hack `tags' to insert `$' by hand.
- Be sure to preserve the value of the eoftoken.
- (reader): Make sure eoftoken is defined.
- Initialize nsyms to 0: now eoftoken is created just like the others.
- * src/print.c (print_grammar): Don't special case the eof token.
- * src/regression.at: Adjust: `$' has value 0, not -1, which was a
- lie anyway, albeit pleasant.
- * tests/calc.at: Exercise error messages with eoftoken.
- Change the grammar so that empty input is invalid.
- Adjust expectations.
- When yyungeting, be sure to use a valid yylloc: use last_yylloc.

-
- * src/gram.h (rule_t): `guard' and `guard_line' are new members.

- members.
- (symbol_list_new): Adjust.
- (copy_action): action_line is the first line, not the last.
- (copy_guard): Just as for actions, store the `action' only, not
- the switch/case/break flesh.
- Don't parse the user action that might follow the guard, let...
- (readgram): do it, i.e., now, there can be an action after a
- guard.
- In other words the guard is just explicitly optional.
- (packgram): Adjust.
- * src/output.c (guards_output): New.
- (output_parser): Call it when needed.
- (output): Also free the guard and attrs obstacks.
- * src/files.c, src/files.h (obstack_save): Remove.

- (conflicts_print, print_reductions): Use a state_t instead of an
- integer when referring to a state.
- As much as possible, depend upon nlookaheads, instead of the
- `lookaheadsp' member of the following state (since lookaheads of
- successive states are successive, the difference between state n + 1
- and n served as the number of lookaheads for state n).

- system.h which uses libgettext.h.
-
-2001-12-15 Akim Demaille <akim@epita.fr>
-
- * src/nullable.c (set_nullable): Useless rules must be skipped,
- otherwise, since we range over their symbols, we might look at a
- nonterminal which no longer ``exists'', i.e., it is not counted in
- `nvars', hence we overflow our arrays.
-
-2001-12-15 Akim Demaille <akim@epita.fr>
-
- The header can also be produced directly, without any obstack!
- Yahoo!
-
- * src/files.c, src/files.h (defines_obstack): Remove.
- (compute_header_macro): Global.
- (defines_obstack_save): Remove.
- * src/reader.c (parse_union_decl): No longer output to
- defines_obstack: its content can be found in the `stype' muscle
- anyway.
- (output_token_translations): Merge into...
- (symbols_output): this.
- Rename as...
- (symbols_save): this.
- (reader): Adjust.
- * src/output.c (header_output): New.
- (output): Call it.
-
-2001-12-15 Akim Demaille <akim@epita.fr>
-
- * src/reader.c (parse_union_decl): Instead of handling two obstack
- simultaneously, use one to define the `stype' muscle, and use the
- value of the latter to fill defines_obstack.
- (copy_comment): Remove.
- (copy_comment2): Work for a single obstack.
- Rename as...
- (copy_comment): this.
-
-2001-12-15 Akim Demaille <akim@epita.fr>
-
- * src/lex.c, src/lex.h (xgetc): No longer static.
- * src/reader.c (parse_union_decl): Revamp.
-
-2001-12-15 Akim Demaille <akim@epita.fr>
-
- Still making progress in separating Bison into (i) input, (ii)
- process, (iii) output: now we can directly output the parser file
- without using table_obstack at all.
-
- * src/files.c, src/files.h (table_obstack): Bye bye.
- (parser_file_name): New.
- * src/files.c (compute_output_file_names): Compute it.
- * src/output.c (actions_output, output_parser)
- (output_master_parser): To a file instead of an obstack.
-
-2001-12-15 Akim Demaille <akim@epita.fr>
-
- Attach actions to rules, instead of pre-outputting them to
- actions_obstack.
-
- * src/gram.h (rule_t): action and action_line are new members.
- * src/reader.c (symbol_list): Likewise.
- (copy_action): Save the actions within the rule.
- (packgram): Save them in rule_table.
- * src/output.c (actions_output): New.
- (output_parser): Use it on `%%actions'.
- (output_rule_data): Don't free rule_table.
- (output): Do it.
- (prepare): Don't save the `action' muscle.
- * src/bison.simple: s/%%action/%%actions/.
-
-2001-12-15 Akim Demaille <akim@epita.fr>
-
- * src/reader.c (copy_action): When --yacc, don't append a `;'
- to the user action: let it fail if lacking.
- Suggested by Arnold Robbins and Tom Tromey.
-
-2001-12-14 Akim Demaille <akim@epita.fr>
-
- * src/lex.c (literalchar): Simply return the char you decoded, non
- longer mess around with obstacks and int pointers.
- Adjust all callers.
-
-2001-12-14 Akim Demaille <akim@epita.fr>
-
- * src/lex.c (literalchar): Don't escape the special characters,
- just decode them, and keep them as char (before, eol was output as
- the 2 char string `\n' etc.).
- * src/output.c (output_rule_data): Use quotearg to output the
- token strings.
-
-2001-12-13 Paul Eggert <eggert@twinsun.com>
-
- * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
- Do not infringe on the global user namespace when using C++.
- (YYFPRINTF, YYSTDERR): New macros, needed for the above.
- All uses of `fprintf' and `stderr' changed.
-
- * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
-
-2001-12-13 Akim Demaille <akim@epita.fr>
-
- The computation of nullable is broken: it doesn't handle empty
- RHS's properly.
-
- * tests/torture.at (GNU AWK Grammar): New.
- * tests/sets.at (Nullable): New.
- * src/nullable.c (set_nullable): Instead of blindly looping over
- `ritems', loop over the rules, and then over their rhs's.
-
- Work around Autotest bugs.
-
- * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
- frame, because Autotest understand lines starting with a `+' as
- traces from the shell. Then, they are not processed properly.
- Admittedly an Autotest bug, but we don't have time to wait for
- Autotest to catch up.
- * tests/regression.at (Broken Closure): Adjust to the new table
- frames.
- Move to...
- * tests/sets.at: here.
-
-2001-12-13 Akim Demaille <akim@epita.fr>
-
- * src/closure.c (closure): Use nrules instead of playing tricks
- with BITS_PER_WORD.
-
-2001-12-13 Akim Demaille <akim@epita.fr>
-
- * src/print.c (print_actions): Output the handling of `$' as the
- traces do: shifting the token EOF. Before EOF was treated as a
- nonterminal.
- * tests/regression.at: Adjust some tests.
- * src/print_graph.c (print_core): Complete the set of items via
- closure. The next-to-final and final states are still unsatisfying,
- but that's to be addressed elsewhere.
- No longer output the rule numbers, but do output the state number.
- A single loop for the shifts + gotos is enough, but picked a
- distinct color for each.
- (print_graph): Initialize and finalize closure.
-
-2001-12-13 Akim Demaille <akim@epita.fr>
-
- * src/reader.c (readgram): Remove dead code, an strip useless
- braces.
- (get_type): Remove, unused.
-
-2001-12-12 Akim Demaille <akim@epita.fr>
-
- * src/complain.h, src/complain.c: Remove error_one_per_line, rely
- on that of lib/error.c.
-
-2001-12-12 Akim Demaille <akim@epita.fr>
-
- Some hosts don't like `/' in includes.
-
- * src/system.h: Include libgettext.h without qualifying the path.
- * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
- $(top_srcdir).
-
-2001-12-11 Marc Autret <autret_m@epita.fr>
-
- * src/output.c (output_parser): Remove useless muscle.
-
-2001-12-11 Marc Autret <autret_m@epita.fr>
-
- * src/bison.simple: Remove #line just before %%epilogue. It
- is now handled in ...

- #line for the epilogue.
-
-2001-12-10 Marc Autret <autret_m@epita.fr>
-
- * src/reader.c (copy_definition): Re-use CPP-outed code which
- replace precedent remove.

-
-2001-12-10 Marc Autret <autret_m@epita.fr>
-
- * src/reader.c (symbols_output): Clean up.

-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/lalr.c (initialize_lookaheads): New. Extracted from...

- * src/lalr.c (lalr): Call it.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/state.h (shifts): Remove the `number' member: shifts are
- attached to state, hence no longer need to be labelled with a
- state number.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- Now that states have a complete set of members, the linked list of
- shifts is useless: just fill directly the state's shifts member.
-
- * src/state.h (shifts): Remove the `next' member.
- * src/LR0.c (first_state, last_state): Remove.
- Adjust the callers.
- (augment_automaton): Don't look for the shifts that must be added
- a shift on EOF: it is those of the state we looked for! But now,
- since shifts are attached, it is no longer needed to looking
- merely by its id: its number.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/LR0.c (augment_automaton): Better variable locality.
- Remove an impossible branch: if there is a state corresponding to
- the start symbol being shifted, then there is shift for the start
- symbol from the initial state.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
- only when appropriate: when insert_start_shifting_state' is not
- invoked.
- * tests/regression.at (Rule Line Numbers): Adjust.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/LR0.c (augment_automaton): Now that all states have shifts,
- merge the two cases addition shifts to the initial state.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/lalr.c (set_state_table): Move to...
- * src/LR0.c: here.
- * src/lalr.c (lalr): Don't call it...
- * src/LR0.c (generate_states): do it.
- * src/LR0.h (first_state): Remove, only the table is used.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/LR0.h (first_shift, first_reduction): Remove.
- * src/lalr.c: Don't use first_shift: find shifts through the
- states.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/LR0.c: Attach shifts to states as soon as they are
- computed.
- * src/lalr.c (set_state_table): Instead of assigning shifts to
- state, just assert that the mapping was properly done.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/LR0.c (insert_start_shift): Rename as...
- (insert_start_shifting_state): this.
- (insert_eof_shifting_state, insert_accepting_state): New.
- (augment_automaton): Adjust.
- Better locality of the variables.
- When looking if the start_symbol is shifted from the initial
- state, using `while (... symbol != start_symbol ...)' sounds
- better than `while (... symbol < start_symbol ...)': If fail
- to see how the order between symbols could be relevant!
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/getargs.h: Don't declare `spec_name_prefix' and
- `spec_file_prefix', declared by src/files.h.
- * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
- * src/muscle_tab.c (muscle_init): Default prefix to NULL.
- * src/output.c (prepare): Adjust.
- * src/reader.c (symbols_output): Likewise.
- * src/vmsgetargs.c: Vaguely adjust, but who cares?
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/muscle_tab.c (muscle_init): NULL is a better default than
- `"0"'.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/reader.c (reader): Calling symbols_output once is enough.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- Now that states have a complete set of members, the linked list of
- reductions is useless: just fill directly the state's reductions
- member.
-
- * src/state.h (struct reductions): Remove member `number' and
- `next'.
- * src/LR0.c (first_reduction, last_reduction): Remove.
- (save_reductions): Don't link the new reductions, store them in
- this_state.
- * src/lalr.c (set_state_table): No need to attach reductions to
- states, it's already done.
- * src/output.c (output_actions): No longer free the shifts, then
- the reductions, then the states: free all the states and their
- members.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/options.c (OPTN, DRTV, BOTH): New.
- (option_table): Use them.
-
- * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
- the job of system.h.
- * src/options.c: Don't include stdio.h and xalloc.h for the same
- reasons.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/output.c (output, prepare): Make sure the values of the
- muscles `action' and `prologue' are 0-terminated.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- Clean up GCC warnings.
-
- * src/reader.c (copy_action): `buf' is not used.
- (parse_skel_decl): Be static.
- * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
- * src/options.h (create_long_option_table): Have a real prototype.
- * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
- (hash_delete_at): Return const void *.
- Adjust casts to preserve the const.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * configure.in: Require 2.52g.
- M4 is not needed, but AUTOM4TE is.
- * m4/m4.m4: Remove.
- * tests/Makefile.am: Adjust.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- One structure for states is enough, even though theoretically
- there are LR(0) states and LALR(1) states.
-
- * src/lalr.h (state_t): Remove.
- (state_table): Be state_t **, not state_t *.
- * src/state.h (core, CORE_ALLOC): Rename as...
- (state_t, STATE_ALLOC): this.
- Add the LALR(1) members: shifts, reductions, errs.
- * src/LR0.c (state_table): Rename as...
- (state_hash): this, to avoid name clashes with the global
- `state_table'.
- * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
- * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- Bison dumps core on bash.y.
- Reported by Pascal Bart.
-
- * src/warshall.c (bitmatrix_print): New.
- (TC): Use it.
- When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
- j must be the outer loop.
- * tests/regression.at (Broken Closure): New.
-
-2001-12-05 Akim Demaille <akim@epita.fr>
-
- * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
- its argument.
- Reported by Peter Hamorsky.

-
- * src/conflicts.c (err_table): Remove.
- (resolve_sr_conflict): Adjust.

- Rename as...
- (state_t.reductions, state_t.shifts): this.
-
-2001-12-05 Akim Demaille <akim@epita.fr>
-
- * src/reduce.c (reduce_grammar_tables): No longer disable the
- removal of useless rules via CPP but via `if (0)', so that the
- compiler still check the code is valid.
- For instance, it should have noticed `rline' no longer exists: use
- the `line' member of rule_t.
- * src/gram.c (dummy, rline): Remove, unused.
-
-2001-12-05 Akim Demaille <akim@epita.fr>
-

- * src/main.c (berror): Remove, unused.
-
-2001-12-05 Akim Demaille <akim@epita.fr>
-
- New experimental feature: if --verbose --trace output all the
- items of a state, not only its kernel.
-
- * src/print.c (print_core): If `trace_flag', then invoke closure
- before outputting the items of the state (print_core is no longer
- a correct name them).
- (print_results): Invoke new_closure/free_closure if needed.
-
-2001-12-05 Akim Demaille <akim@epita.fr>
-
- * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
- * src/closure.c, src/closure.h (itemsetsize): Rename as...
- (nitemset): for consistency with the rest of the project.
-
-2001-12-05 Akim Demaille <akim@epita.fr>
-
- * src/closure.c (print_closure): Improve.
- (closure): Use it for printing input and output.
-
-2001-12-05 Akim Demaille <akim@epita.fr>

- locality, BITISSET, RESETBIT etc.
-
-2001-12-05 Akim Demaille <akim@epita.fr>
-
- Pessimize the code to simplify it: from now on, all the states
- have a valid SHIFTS, which NSHIFTS is possibly 0.
-
- * src/LR0.c (shifts_new): Be global and move to..
- * src/state.c, src/state.h: here.
- * src/conflicts, src/lalr.c, src/output.c, src/print.c,

- Better variable locality.
-
-2001-12-05 Akim Demaille <akim@epita.fr>
-
- * src/lalr.c (matrix_print): New.

- * src/lalr.c (build_relations): Adjust.
-
-2001-12-05 Akim Demaille <akim@epita.fr>
-
- * src/lalr.c (transpose): Free the memory allocated to the
- argument, as it is replaced by the results by the unique caller.
- (build_relations): Merely invoke transpose: it handles the memory
- deallocation.
- Improve variable locality.
- Avoid variables used as mere abbreviations.

- `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
-
-2001-12-05 Akim Demaille <akim@epita.fr>
-
- Because useless nonterminals are now kept alive (instead of being
- `destroyed'), we now sometimes examine them, and store information
- related to them. Hence we need to know their number, and adjust
- memory allocations.
-
- * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
- static.
- * src/LR0.c (allocate_itemsets): The memory allocated to
- `symbol_count' was used for two different purpose: once to count
- the number of occurrences of each symbol, and later reassigned to
- `shift_symbol', containing the symbol that can be shifted from a
- given state.
- Deobfuscate, i.e., allocate, use and free `symbol_count' here
- only, and...
- (new_itemsets): Allocate `shift_symbol' here.
- (allocate_itemsets): symbol_count includes useless nonterminals.
- Make room for them.
- (free_storage): Use `free', not `XFREE', for pointers that cannot
- be null.
-
-2001-12-05 Akim Demaille <akim@epita.fr>

-
- * src/gram.c, src/gram.h (ritem_print): New.
- * src/gram.c (dummy): Remove, now there is actual code in gram.c.
- (This useless function was defined only to work around VMS linkers
- that can't handle compilation units with variables only).
- * src/reduce.c (dump_grammar): Use it to trace the construction of
- ritem.
-
-2001-12-04 Paul Eggert <eggert@twinsun.com>
-
- * src/bison.simple (union yyalloc): Change member names
- to be the same as the stack names.
- (yyparse): yyptr is now union yyalloc *, not char *.
- (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
- and may generate better code on some machines.
- (yystpcpy): Use prototype if __STDC__ is defined, not just
- if __cplusplus is defined.
-
-2001-11-30 Akim Demaille <akim@epita.fr>
-

-
- Test also `--verbose', `--defines' and `--name-prefix'. Testing
- the latter demonstrates a flaw in the handling of non debugging
- parsers introduced by myself on 2000-03-16: `#define yydebug 0'
- was used in order to simplify:
-
- #if YYDEBUG
- if (yydebug)
- {
- ...
- }
- #endif
-
- into
-
- if (yydebug)
- {
- ...
- }
-
- unfortunately this leads to a CPP conflict when
- `--name-prefix=foo' is used since it produces `#define yydebug
- foodebug'.
-
- * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
- (YYDPRINTF): New macro.
- Spread its use.
- * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
- the bison options.
- Also test `--verbose', `--defines' and `--name-prefix'.

-
- Use the more standard files `xalloc.h' and `xmalloc.c' instead of
- Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
- difficult and introduced a lot of core dump. It turns out that
- Bison used an implementation of `xmalloc' based on `calloc', and
- at various places it does depend upon the initialization to 0. I
- have not tried to isolate the pertinent places, and all the former
- calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
- someone should address this issue.

-Installation Instructions
-*************************
-
-Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005 Free
-Software Foundation, Inc.
-
-This file is free documentation; the Free Software Foundation gives
-unlimited permission to copy, distribute and modify it.
-
-Basic Installation
-==================
-
-These are generic installation instructions.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
- It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring. (Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.)
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
- The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'. You only need
-`configure.ac' if you want to change it or regenerate `configure' using
-a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system. If you're
- using `csh' on an old version of System V, you might need to type
- `sh ./configure' instead to prevent `csh' from trying to execute
- `configure' itself.
-
- Running `configure' takes awhile. While running, it prints some
- messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package.
-
- 4. Type `make install' to install the programs and any data files and
- documentation.
-
- 5. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.
-
-Compilers and Options
-=====================
-
-Some systems require unusual options for compilation or linking that the
-`configure' script does not know about. Run `./configure --help' for
-details on some of the pertinent environment variables.
-
- You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment. Here
-is an example:
-
- ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
-
- *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
- If you have to use a `make' that does not support the `VPATH'
-variable, you have to compile the package for one architecture at a
-time in the source code directory. After you have installed the
-package for one architecture, use `make distclean' before reconfiguring
-for another architecture.
-
-Installation Names
-==================
-
-By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc. You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX'.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-There may be some features `configure' cannot figure out automatically,
-but needs to determine by the type of machine the package will run on.
-Usually, assuming the package is built to be run on the _same_
-architectures, `configure' can figure that out, but if it prints a
-message saying it cannot guess the machine type, give it the
-`--build=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
- CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
- OS KERNEL-OS
-
- See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
- If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
- If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-If you want to set default values for `configure' scripts to share, you
-can create a site shell script called `config.site' that gives default
-values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-Variables not defined in a site shell script can be set in the
-environment passed to `configure'. However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost. In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'. For example:
-
- ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script). Here is a another example:
-
- /bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
-configuration-related scripts to be executed by `/bin/bash'.
-
-`configure' Invocation
-======================
-
-`configure' recognizes the following options to control how it operates.
-
-`--help'
-`-h'
- Print a summary of the options to `configure', and exit.
-
-`--version'
-`-V'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`--cache-file=FILE'
- Enable the cache: use and save the results of the tests in FILE,
- traditionally `config.cache'. FILE defaults to `/dev/null' to
- disable caching.
-
-`--config-cache'
-`-C'
- Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made. To
- suppress all normal output, redirect it to `/dev/null' (any error
- messages will still be shown).
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`configure' also accepts some other, not widely useful, options. Run
-`configure --help' for more details.

-----------
-
-Changes in version 2.3, 2006-06-05:
-
-* GLR grammars should now use `YYRECOVERING ()' instead of `YYRECOVERING',
- for compatibility with LALR(1) grammars.
-
-* It is now documented that any definition of YYSTYPE or YYLTYPE should
- be to a type name that does not contain parentheses or brackets.
-
-Changes in version 2.2, 2006-05-19:
-
-* The distribution terms for all Bison-generated parsers now permit
- using the parsers in nonfree programs. Previously, this permission
- was granted only for Bison-generated LALR(1) parsers in C.
-
-* %name-prefix changes the namespace name in C++ outputs.
-
-* The C++ parsers export their token_type.
-
-* Bison now allows multiple %union declarations, and concatenates
- their contents together.
-
-* New warning: unused values
- Right-hand side symbols whose values are not used are reported,
- if the symbols have destructors. For instance:
-
- exp: exp "?" exp ":" exp { $1 ? $1 : $3; }
- | exp "+" exp
- ;
-
- will trigger a warning about $$ and $5 in the first rule, and $3 in
- the second ($1 is copied to $$ by the default rule). This example
- most likely contains three errors, and could be rewritten as:
-
- exp: exp "?" exp ":" exp
- { $$ = $1 ? $3 : $5; free ($1 ? $5 : $3); free ($1); }
- | exp "+" exp
- { $$ = $1 ? $1 : $3; if ($1) free ($3); }
- ;
-
- However, if the original actions were really intended, memory leaks
- and all, the warnings can be suppressed by letting Bison believe the
- values are used, e.g.:
-
- exp: exp "?" exp ":" exp { $1 ? $1 : $3; (void) ($$, $5); }
- | exp "+" exp { $$ = $1; (void) $3; }
- ;
-
- If there are mid-rule actions, the warning is issued if no action
- uses it. The following triggers no warning: $1 and $3 are used.
-
- exp: exp { push ($1); } '+' exp { push ($3); sum (); };
-
- The warning is intended to help catching lost values and memory leaks.
- If a value is ignored, its associated memory typically is not reclaimed.
-
-* %destructor vs. YYABORT, YYACCEPT, and YYERROR.
- Destructors are now called when user code invokes YYABORT, YYACCEPT,
- and YYERROR, for all objects on the stack, other than objects
- corresponding to the right-hand side of the current rule.
-
-* %expect, %expect-rr
- Incorrect numbers of expected conflicts are now actual errors,
- instead of warnings.
-
-* GLR, YACC parsers.
- The %parse-params are available in the destructors (and the
- experimental printers) as per the documentation.
-
-* Bison now warns if it finds a stray `$' or `@' in an action.
-
-* %require "VERSION"
- This specifies that the grammar file depends on features implemented
- in Bison version VERSION or higher.
-
-* lalr1.cc: The token and value types are now class members.
- The tokens were defined as free form enums and cpp macros. YYSTYPE
- was defined as a free form union. They are now class members:
- tokens are enumerations of the `yy::parser::token' struct, and the
- semantic values have the `yy::parser::semantic_type' type.
-
- If you do not want or can update to this scheme, the directive
- `%define "global_tokens_and_yystype" "1"' triggers the global
- definition of tokens and YYSTYPE. This change is suitable both
- for previous releases of Bison, and this one.
-
- If you wish to update, then make sure older version of Bison will
- fail using `%require "2.2"'.
-
-* DJGPP support added.
-
-Changes in version 2.1, 2005-09-16:
-
-* The C++ lalr1.cc skeleton supports %lex-param.
-
-* Bison-generated parsers now support the translation of diagnostics like
- "syntax error" into languages other than English. The default
- language is still English. For details, please see the new
- Internationalization section of the Bison manual. Software
- distributors should also see the new PACKAGING file. Thanks to
- Bruno Haible for this new feature.
-
-* Wording in the Bison-generated parsers has been changed slightly to
- simplify translation. In particular, the message "memory exhausted"
- has replaced "parser stack overflow", as the old message was not
- always accurate for modern Bison-generated parsers.
-
-* Destructors are now called when the parser aborts, for all symbols left
- behind on the stack. Also, the start symbol is now destroyed after a
- successful parse. In both cases, the behavior was formerly inconsistent.
-
-* When generating verbose diagnostics, Bison-generated parsers no longer
- quote the literal strings associated with tokens. For example, for
- a syntax error associated with '%token NUM "number"' they might
- print 'syntax error, unexpected number' instead of 'syntax error,
- unexpected "number"'.
-
-Changes in version 2.0, 2004-12-25:
-
-* Possibly-incompatible changes
-
- - Bison-generated parsers no longer default to using the alloca function
- (when available) to extend the parser stack, due to widespread
- problems in unchecked stack-overflow detection. You can "#define
- YYSTACK_USE_ALLOCA 1" to require the use of alloca, but please read
- the manual to determine safe values for YYMAXDEPTH in that case.
-
- - Error token location.
- During error recovery, the location of the syntax error is updated
- to cover the whole sequence covered by the error token: it includes
- the shifted symbols thrown away during the first part of the error
- recovery, and the lookahead rejected during the second part.
-
- - Semicolon changes:
- . Stray semicolons are no longer allowed at the start of a grammar.
- . Semicolons are now required after in-grammar declarations.
-
- - Unescaped newlines are no longer allowed in character constants or
- string literals. They were never portable, and GCC 3.4.0 has
- dropped support for them. Better diagnostics are now generated if
- forget a closing quote.
-
- - NUL bytes are no longer allowed in Bison string literals, unfortunately.
-
-* New features
-
- - GLR grammars now support locations.
-
- - New directive: %initial-action.
- This directive allows the user to run arbitrary code (including
- initializing @$) from yyparse before parsing starts.
-
- - A new directive "%expect-rr N" specifies the expected number of
- reduce/reduce conflicts in GLR parsers.
-
- - %token numbers can now be hexadecimal integers, e.g., `%token FOO 0x12d'.
- This is a GNU extension.
-
- - The option `--report=lookahead' was changed to `--report=look-ahead'.
- The old spelling still works, but is not documented and will be
- removed.
-
- - Experimental %destructor support has been added to lalr1.cc.
-
- - New configure option --disable-yacc, to disable installation of the
- yacc command and -ly library introduced in 1.875 for POSIX conformance.
-
-* Bug fixes
-
- - For now, %expect-count violations are now just warnings, not errors.
- This is for compatibility with Bison 1.75 and earlier (when there are
- reduce/reduce conflicts) and with Bison 1.30 and earlier (when there
- are too many or too few shift/reduce conflicts). However, in future
- versions of Bison we plan to improve the %expect machinery so that
- these violations will become errors again.
-
- - Within Bison itself, numbers (e.g., goto numbers) are no longer
- arbitrarily limited to 16-bit counts.
-
- - Semicolons are now allowed before "|" in grammar rules, as POSIX requires.
-
-Changes in version 1.875, 2003-01-01:
-
-* The documentation license has been upgraded to version 1.2
- of the GNU Free Documentation License.
-
-* syntax error processing
-
- - In Yacc-style parsers YYLLOC_DEFAULT is now used to compute error
- locations too. This fixes bugs in error-location computation.
-
- - %destructor
- It is now possible to reclaim the memory associated to symbols
- discarded during error recovery. This feature is still experimental.
-
- - %error-verbose
- This new directive is preferred over YYERROR_VERBOSE.
-
- - #defining yyerror to steal internal variables is discouraged.
- It is not guaranteed to work forever.
-
-* POSIX conformance
-
- - Semicolons are once again optional at the end of grammar rules.
- This reverts to the behavior of Bison 1.33 and earlier, and improves
- compatibility with Yacc.
-
- - `parse error' -> `syntax error'
- Bison now uniformly uses the term `syntax error'; formerly, the code
- and manual sometimes used the term `parse error' instead. POSIX
- requires `syntax error' in diagnostics, and it was thought better to
- be consistent.
-
- - The documentation now emphasizes that yylex and yyerror must be
- declared before use. C99 requires this.
-
- - Bison now parses C99 lexical constructs like UCNs and
- backslash-newline within C escape sequences, as POSIX 1003.1-2001 requires.
-
- - File names are properly escaped in C output. E.g., foo\bar.y is
- output as "foo\\bar.y".
-
- - Yacc command and library now available
- The Bison distribution now installs a `yacc' command, as POSIX requires.
- Also, Bison now installs a small library liby.a containing
- implementations of Yacc-compatible yyerror and main functions.
- This library is normally not useful, but POSIX requires it.
-
- - Type clashes now generate warnings, not errors.
-
- - If the user does not define YYSTYPE as a macro, Bison now declares it
- using typedef instead of defining it as a macro.
- For consistency, YYLTYPE is also declared instead of defined.
-
-* Other compatibility issues
-
- - %union directives can now have a tag before the `{', e.g., the
- directive `%union foo {...}' now generates the C code
- `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
- The default union tag is `YYSTYPE', for compatibility with Solaris 9 Yacc.
- For consistency, YYLTYPE's struct tag is now `YYLTYPE' not `yyltype'.
- This is for compatibility with both Yacc and Bison 1.35.
-
- - `;' is output before the terminating `}' of an action, for
- compatibility with Bison 1.35.
-
- - Bison now uses a Yacc-style format for conflict reports, e.g.,
- `conflicts: 2 shift/reduce, 1 reduce/reduce'.
-
- - `yystype' and `yyltype' are now obsolescent macros instead of being
- typedefs or tags; they are no longer documented and are planned to be
- withdrawn in a future release.
-
-* GLR parser notes
-
- - GLR and inline
- Users of Bison have to decide how they handle the portability of the
- C keyword `inline'.
-
- - `parsing stack overflow...' -> `parser stack overflow'
- GLR parsers now report `parser stack overflow' as per the Bison manual.
-
-* Bison now warns if it detects conflicting outputs to the same file,
- e.g., it generates a warning for `bison -d -o foo.h foo.y' since
- that command outputs both code and header to foo.h.
-
-* #line in output files
- - --no-line works properly.
-
-* Bison can no longer be built by a K&R C compiler; it requires C89 or
- later to be built. This change originally took place a few versions
- ago, but nobody noticed until we recently asked someone to try
- building Bison with a K&R C compiler.
-
-Changes in version 1.75, 2002-10-14:
-
-* Bison should now work on 64-bit hosts.
-
-* Indonesian translation thanks to Tedi Heriyanto.
-
-* GLR parsers
- Fix spurious parse errors.
-
-* Pure parsers
- Some people redefine yyerror to steal yyparse' private variables.
- Reenable this trick until an official feature replaces it.
-
-* Type Clashes
- In agreement with POSIX and with other Yaccs, leaving a default
- action is valid when $$ is untyped, and $1 typed:
-
- untyped: ... typed;
-
- but the converse remains an error:
-
- typed: ... untyped;
-
-* Values of mid-rule actions
- The following code:
-
- foo: { ... } { $$ = $1; } ...
-
- was incorrectly rejected: $1 is defined in the second mid-rule
- action, and is equal to the $$ of the first mid-rule action.
-
-Changes in version 1.50, 2002-10-04:
-
-* GLR parsing
- The declaration
- %glr-parser
- causes Bison to produce a Generalized LR (GLR) parser, capable of handling
- almost any context-free grammar, ambiguous or not. The new declarations
- %dprec and %merge on grammar rules allow parse-time resolution of
- ambiguities. Contributed by Paul Hilfinger.
-
- Unfortunately Bison 1.50 does not work properly on 64-bit hosts
- like the Alpha, so please stick to 32-bit hosts for now.
-
-* Output Directory
- When not in Yacc compatibility mode, when the output file was not
- specified, running `bison foo/bar.y' created `foo/bar.c'. It
- now creates `bar.c'.
-
-* Undefined token
- The undefined token was systematically mapped to 2 which prevented
- the use of 2 by the user. This is no longer the case.
-
-* Unknown token numbers
- If yylex returned an out of range value, yyparse could die. This is
- no longer the case.
-
-* Error token
- According to POSIX, the error token must be 256.
- Bison extends this requirement by making it a preference: *if* the
- user specified that one of her tokens is numbered 256, then error
- will be mapped onto another number.
-
-* Verbose error messages
- They no longer report `..., expecting error or...' for states where
- error recovery is possible.
-
-* End token
- Defaults to `$end' instead of `$'.
-
-* Error recovery now conforms to documentation and to POSIX
- When a Bison-generated parser encounters a syntax error, it now pops
- the stack until it finds a state that allows shifting the error
- token. Formerly, it popped the stack until it found a state that
- allowed some non-error action other than a default reduction on the
- error token. The new behavior has long been the documented behavior,
- and has long been required by POSIX. For more details, please see
- Paul Eggert, "Reductions during Bison error handling" (2002-05-20)
- <http://lists.gnu.org/archive/html/bug-bison/2002-05/msg00038.html>.
-
-* Traces
- Popped tokens and nonterminals are now reported.
-
-* Larger grammars
- Larger grammars are now supported (larger token numbers, larger grammar
- size (= sum of the LHS and RHS lengths), larger LALR tables).
- Formerly, many of these numbers ran afoul of 16-bit limits;
- now these limits are 32 bits on most hosts.
-
-* Explicit initial rule
- Bison used to play hacks with the initial rule, which the user does
- not write. It is now explicit, and visible in the reports and
- graphs as rule 0.
-
-* Useless rules
- Before, Bison reported the useless rules, but, although not used,
- included them in the parsers. They are now actually removed.
-
-* Useless rules, useless nonterminals
- They are now reported, as a warning, with their locations.
-
-* Rules never reduced
- Rules that can never be reduced because of conflicts are now
- reported.
-
-* Incorrect `Token not used'
- On a grammar such as
-
- %token useless useful
- %%
- exp: '0' %prec useful;
-
- where a token was used to set the precedence of the last rule,
- bison reported both `useful' and `useless' as useless tokens.
-
-* Revert the C++ namespace changes introduced in 1.31
- as they caused too many portability hassles.
-
-* Default locations
- By an accident of design, the default computation of @$ was
- performed after another default computation was performed: @$ = @1.
- The latter is now removed: YYLLOC_DEFAULT is fully responsible of
- the computation of @$.
-
-* Token end-of-file
- The token end of file may be specified by the user, in which case,
- the user symbol is used in the reports, the graphs, and the verbose
- error messages instead of `$end', which remains being the default.
- For instance
- %token MYEOF 0
- or
- %token MYEOF 0 "end of file"
-
-* Semantic parser
- This old option, which has been broken for ages, is removed.
-
-* New translations
- Brazilian Portuguese, thanks to Alexandre Folle de Menezes.
- Croatian, thanks to Denis Lackovic.
-
-* Incorrect token definitions
- When given `%token 'a' "A"', Bison used to output `#define 'a' 65'.
-
-* Token definitions as enums
- Tokens are output both as the traditional #define's, and, provided
- the compiler supports ANSI C or is a C++ compiler, as enums.
- This lets debuggers display names instead of integers.
-
-* Reports
- In addition to --verbose, bison supports --report=THINGS, which
- produces additional information:
- - itemset
- complete the core item sets with their closure
- - lookahead [changed to `look-ahead' in 1.875e and later]
- explicitly associate look-ahead tokens to items
- - solved
- describe shift/reduce conflicts solving.
- Bison used to systematically output this information on top of
- the report. Solved conflicts are now attached to their states.
-
-* Type clashes
- Previous versions don't complain when there is a type clash on
- the default action if the rule has a mid-rule action, such as in:
-
- %type <foo> bar
- %%
- bar: '0' {} '0';
-
- This is fixed.
-
-* GNU M4 is now required when using Bison.
-
-Changes in version 1.35, 2002-03-25:
-
-* C Skeleton
- Some projects use Bison's C parser with C++ compilers, and define
- YYSTYPE as a class. The recent adjustment of C parsers for data
- alignment and 64 bit architectures made this impossible.
-
- Because for the time being no real solution for C++ parser
- generation exists, kludges were implemented in the parser to
- maintain this use. In the future, when Bison has C++ parsers, this
- kludge will be disabled.
-
- This kludge also addresses some C++ problems when the stack was
- extended.
-
-Changes in version 1.34, 2002-03-12:
-
-* File name clashes are detected
- $ bison foo.y -d -o foo.x
- fatal error: header and parser would both be named `foo.x'
-
-* A missing `;' at the end of a rule triggers a warning
- In accordance with POSIX, and in agreement with other
- Yacc implementations, Bison will mandate this semicolon in the near
- future. This eases the implementation of a Bison parser of Bison
- grammars by making this grammar LALR(1) instead of LR(2). To
- facilitate the transition, this release introduces a warning.
-
-* Revert the C++ namespace changes introduced in 1.31, as they caused too
- many portability hassles.
-
-* DJGPP support added.
-
-* Fix test suite portability problems.
-
-Changes in version 1.33, 2002-02-07:
-
-* Fix C++ issues
- Groff could not be compiled for the definition of size_t was lacking
- under some conditions.
-
-* Catch invalid @n
- As is done with $n.
-
-Changes in version 1.32, 2002-01-23:
-
-* Fix Yacc output file names
-
-* Portability fixes
-
-* Italian, Dutch translations
-
-Changes in version 1.31, 2002-01-14:
-
-* Many Bug Fixes
-
-* GNU Gettext and %expect
- GNU Gettext asserts 10 s/r conflicts, but there are 7. Now that
- Bison dies on incorrect %expectations, we fear there will be
- too many bug reports for Gettext, so _for the time being_, %expect
- does not trigger an error when the input file is named `plural.y'.
-
-* Use of alloca in parsers
- If YYSTACK_USE_ALLOCA is defined to 0, then the parsers will use
- malloc exclusively. Since 1.29, but was not NEWS'ed.
-
- alloca is used only when compiled with GCC, to avoid portability
- problems as on AIX.
-
-* yyparse now returns 2 if memory is exhausted; formerly it dumped core.
-
-* When the generated parser lacks debugging code, YYDEBUG is now 0
- (as POSIX requires) instead of being undefined.
-
-* User Actions
- Bison has always permitted actions such as { $$ = $1 }: it adds the
- ending semicolon. Now if in Yacc compatibility mode, the semicolon
- is no longer output: one has to write { $$ = $1; }.
-
-* Better C++ compliance
- The output parsers try to respect C++ namespaces.
- [This turned out to be a failed experiment, and it was reverted later.]
-
-* Reduced Grammars
- Fixed bugs when reporting useless nonterminals.
-
-* 64 bit hosts
- The parsers work properly on 64 bit hosts.
-
-* Error messages
- Some calls to strerror resulted in scrambled or missing error messages.
-
-* %expect
- When the number of shift/reduce conflicts is correct, don't issue
- any warning.
-
-* The verbose report includes the rule line numbers.
-
-* Rule line numbers are fixed in traces.
-
-* Swedish translation
-
-* Parse errors
- Verbose parse error messages from the parsers are better looking.
- Before: parse error: unexpected `'/'', expecting `"number"' or `'-'' or `'(''
- Now: parse error: unexpected '/', expecting "number" or '-' or '('
-
-* Fixed parser memory leaks.
- When the generated parser was using malloc to extend its stacks, the
- previous allocations were not freed.
-
-* Fixed verbose output file.
- Some newlines were missing.
- Some conflicts in state descriptions were missing.
-
-* Fixed conflict report.
- Option -v was needed to get the result.
-
-* %expect
- Was not used.
- Mismatches are errors, not warnings.
-
-* Fixed incorrect processing of some invalid input.
-
-* Fixed CPP guards: 9foo.h uses BISON_9FOO_H instead of 9FOO_H.
-
-* Fixed some typos in the documentation.
-
-* %token MY_EOF 0 is supported.
- Before, MY_EOF was silently renumbered as 257.
-
-* doc/refcard.tex is updated.
-
-* %output, %file-prefix, %name-prefix.
- New.
-
-* --output
- New, aliasing `--output-file'.
-
-Changes in version 1.30, 2001-10-26:
-
-* `--defines' and `--graph' have now an optional argument which is the
- output file name. `-d' and `-g' do not change; they do not take any
- argument.
-
-* `%source_extension' and `%header_extension' are removed, failed
- experiment.
-
-* Portability fixes.
-
-Changes in version 1.29, 2001-09-07:
-
-* The output file does not define const, as this caused problems when used
- with common autoconfiguration schemes. If you still use ancient compilers
- that lack const, compile with the equivalent of the C compiler option
- `-Dconst='. autoconf's AC_C_CONST macro provides one way to do this.
-
-* Added `-g' and `--graph'.
-
-* The Bison manual is now distributed under the terms of the GNU FDL.
-
-* The input and the output files has automatically a similar extension.
-
-* Russian translation added.
-
-* NLS support updated; should hopefully be less troublesome.
-
-* Added the old Bison reference card.
-
-* Added `--locations' and `%locations'.
-
-* Added `-S' and `--skeleton'.
-
-* `%raw', `-r', `--raw' is disabled.
-
-* Special characters are escaped when output. This solves the problems
- of the #line lines with path names including backslashes.
-
-* New directives.
- `%yacc', `%fixed_output_files', `%defines', `%no_parser', `%verbose',
- `%debug', `%source_extension' and `%header_extension'.
-
-* @$
- Automatic location tracking.
-
-Changes in version 1.28, 1999-07-06:
-
-* Should compile better now with K&R compilers.
-
-* Added NLS.
-
-* Fixed a problem with escaping the double quote character.
-
-* There is now a FAQ.
-
-Changes in version 1.27:
-
-* The make rule which prevented bison.simple from being created on
- some systems has been fixed.
-
-Changes in version 1.26:
-
-* Bison now uses automake.
-
-* New mailing lists: <bug-bison@gnu.org> and <help-bison@gnu.org>.
-
-* Token numbers now start at 257 as previously documented, not 258.
-
-* Bison honors the TMPDIR environment variable.
-
-* A couple of buffer overruns have been fixed.
-
-* Problems when closing files should now be reported.
-
-* Generated parsers should now work even on operating systems which do
- not provide alloca().
-
-Changes in version 1.25, 1995-10-16:
-
-* Errors in the input grammar are not fatal; Bison keeps reading
-the grammar file, and reports all the errors found in it.
-
-* Tokens can now be specified as multiple-character strings: for
-example, you could use "<=" for a token which looks like <=, instead
-of chosing a name like LESSEQ.
-
-* The %token_table declaration says to write a table of tokens (names
-and numbers) into the parser file. The yylex function can use this
-table to recognize multiple-character string tokens, or for other
-purposes.
-
-* The %no_lines declaration says not to generate any #line preprocessor
-directives in the parser file.
-
-* The %raw declaration says to use internal Bison token numbers, not
-Yacc-compatible token numbers, when token names are defined as macros.
-
-* The --no-parser option produces the parser tables without including
-the parser engine; a project can now use its own parser engine.
-The actions go into a separate file called NAME.act, in the form of
-a switch statement body.
-
-Changes in version 1.23:
-
-The user can define YYPARSE_PARAM as the name of an argument to be
-passed into yyparse. The argument should have type void *. It should
-actually point to an object. Grammar actions can access the variable
-by casting it to the proper pointer type.
-
-Line numbers in output file corrected.
-
-Changes in version 1.22:
-
---help option added.
-
-Changes in version 1.20:
-
-Output file does not redefine const for C++.
-
-Local Variables:
-mode: outline
-End:

-Packaging hints for binary package distributors
-===============================================
-
-Although the source of the bison package comes as a single package,
-in distributions of binary packages the installed files should
-be split into two packages:
-
- bison-runtime
- Contents: Runtime libraries and programs.
- Audience: Anyone who wants to run internationalized programs
- that contain Bison-generated parsers.
-
- bison
- Contents: Tools and documentation for developers that use Bison.
- Audience: Anyone who wants to develop programs that use parsers.
- Dependencies: requires bison-runtime.
-
-The 'bison-runtime' binary package is much smaller than the 'bison'
-binary package. It should be included in any distribution that
-contains localized programs that use the diagnostics contained in
-Bison-generated parsers.
-
-If you want to install both packages at the same time, you simply do
-at the toplevel directory:
-
- ./configure
- make
- make install
-
-After installation, the file
-
- $prefix/share/locale/*/LC_MESSAGES/bison-runtime.mo
-
-belongs to the bison-runtime package; all other installed files belong
-to the bison package.

-* Header guards
-
-From Franc,ois: should we keep the directory part in the CPP guard?
-
-
-* Yacc.c: CPP Macros
-
-Do some people use YYPURE, YYLSP_NEEDED like we do in the test suite?
-They should not: it is not documented. But if they need to, let's
-find something clean (not like YYLSP_NEEDED...).
-
-
-* Documentation
-Before releasing, make sure the documentation ("Understanding your
-parser") refers to the current `output' format.
-
-* lalr1.cc
-** vector
-Move to using vector, drop stack.hh.
-
-** I18n
-Catch up with yacc.c.
-
-* Report
-
-** GLR
-How would Paul like to display the conflicted actions? In particular,
-what when two reductions are possible on a given look-ahead token, but one is
-part of $default. Should we make the two reductions explicit, or just
-keep $default? See the following point.
-
-** Disabled Reductions
-See `tests/conflicts.at (Defaulted Conflicted Reduction)', and decide
-what we want to do.
-
-** Documentation
-Extend with error productions. The hard part will probably be finding
-the right rule so that a single state does not exhibit too many yet
-undocumented ``features''. Maybe an empty action ought to be
-presented too. Shall we try to make a single grammar with all these
-features, or should we have several very small grammars?
-
-** --report=conflict-path
-Provide better assistance for understanding the conflicts by providing
-a sample text exhibiting the (LALR) ambiguity. See the paper from
-DeRemer and Penello: they already provide the algorithm.
-
-
-* Extensions
-
-** Labeling the symbols
-Have a look at the Lemon parser generator: instead of $1, $2 etc. they
-can name the values. This is much more pleasant. For instance:
-
- exp (res): exp (a) '+' exp (b) { $res = $a + $b; };
-
-I love this. I have been bitten too often by the removal of the
-symbol, and forgetting to shift all the $n to $n-1. If you are
-unlucky, it compiles...
-
-But instead of using $a etc., we can use regular variables. And
-instead of using (), I propose to use `:' (again). Paul suggests
-supporting `->' in addition to `:' to separate LHS and RHS. In other
-words:
-
- r:exp -> a:exp '+' b:exp { r = a + b; };
-
-That requires an significant improvement of the grammar parser. Using
-GLR would be nice. It also requires that Bison know the type of the
-symbols (which will be useful for %include anyway). So we have some
-time before...
-
-Note that there remains the problem of locations: `@r'?
-
-
-** $-1
-We should find a means to provide an access to values deep in the
-stack. For instance, instead of
-
- baz: qux { $$ = $<foo>-1 + $<bar>0 + $1; }
-
-we should be able to have:
-
- foo($foo) bar($bar) baz($bar): qux($qux) { $baz = $foo + $bar + $qux; }
-
-Or something like this.
-
-** %if and the like
-It should be possible to have %if/%else/%endif. The implementation is
-not clear: should it be lexical or syntactic. Vadim Maslow thinks it
-must be in the scanner: we must not parse what is in a switched off
-part of %if. Akim Demaille thinks it should be in the parser, so as
-to avoid falling into another CPP mistake.
-
-** -D, --define-muscle NAME=VALUE
-To define muscles via cli. Or maybe support directly NAME=VALUE?
-
-** XML Output
-There are couple of available extensions of Bison targeting some XML
-output. Some day we should consider including them. One issue is
-that they seem to be quite orthogonal to the parsing technique, and
-seem to depend mostly on the possibility to have some code triggered
-for each reduction. As a matter of fact, such hooks could also be
-used to generate the yydebug traces. Some generic scheme probably
-exists in there.
-
-XML output for GNU Bison and gcc
- http://www.cs.may.ie/~jpower/Research/bisonXML/

-XML output for GNU Bison

-
-* Unit rules
-Maybe we could expand unit rules, i.e., transform
-
- exp: arith | bool;
- arith: exp '+' exp;
- bool: exp '&' exp;
-
-into
-
- exp: exp '+' exp | exp '&' exp;
-
-when there are no actions. This can significantly speed up some
-grammars. I can't find the papers. In particular the book `LR
-parsing: Theory and Practice' is impossible to find, but according to
-`Parsing Techniques: a Practical Guide', it includes information about
-this issue. Does anybody have it?
-
-
-
-* Documentation
-
-** History/Bibliography
-Some history of Bison and some bibliography would be most welcome.
-Are there any Texinfo standards for bibliography?
-
-
-
-* Java, Fortran, etc.
-
-
-** Java
-
-There are a couple of proposed outputs:
-
-- BYACC/J
- which is based on Byacc.
- <http://troi.lincom-asg.com/~rjamison/byacc/>
-
-- Bison Java
- which is based on Bison.
- <http://www.goice.co.jp/member/mo/hack-progs/bison-java.html>
-
-Sebastien Serrurier (serrur_s@epita.fr) is working on this: he is
-expected to contact the authors, design the output, and implement it
-into Bison.
-
-
-* Coding system independence
-Paul notes:
-
- Currently Bison assumes 8-bit bytes (i.e. that UCHAR_MAX is
- 255). It also assumes that the 8-bit character encoding is
- the same for the invocation of 'bison' as it is for the
- invocation of 'cc', but this is not necessarily true when
- people run bison on an ASCII host and then use cc on an EBCDIC
- host. I don't think these topics are worth our time
- addressing (unless we find a gung-ho volunteer for EBCDIC or
- PDP-10 ports :-) but they should probably be documented
- somewhere.
-
- More importantly, Bison does not currently allow NUL bytes in
- tokens, either via escapes (e.g., "x\0y") or via a NUL byte in
- the source code. This should get fixed.
-
-* --graph
-Show reductions.
-
-* Broken options ?
-** %no-parser
-** %token-table
-** Skeleton strategy
-Must we keep %no-parser? %token-table?
-
-* src/print_graph.c
-Find the best graph parameters.
-
-* BTYacc
-See if we can integrate backtracking in Bison. Charles-Henri de
-Boysson <de-boy_c@epita.fr> is working on this, and already has some
-results. Vadim Maslow, the maintainer of BTYacc was contacted, and we
-stay in touch with him. Adjusting the Bison grammar parser will be
-needed to support some extra BTYacc features. This is less urgent.
-
-** Keeping the conflicted actions
-First, analyze the differences between byacc and btyacc (I'm referring
-to the executables). Find where the conflicts are preserved.
-
-** Compare with the GLR tables
-See how isomorphic the way BTYacc and the way the GLR adjustments in
-Bison are compatible. *As much as possible* one should try to use the
-same implementation in the Bison executables. I insist: it should be
-very feasible to use the very same conflict tables.
-
-** Adjust the skeletons
-Import the skeletons for C and C++.
-
-** Improve the skeletons
-Have them support yysymprint, yydestruct and so forth.
-
-
-* Precedence
-
-** Partial order
-It is unfortunate that there is a total order for precedence. It
-makes it impossible to have modular precedence information. We should
-move to partial orders (sounds like series/parallel orders to me).
-
-This will be possible with a Bison parser for the grammar, as it will
-make it much easier to extend the grammar.
-
-** Correlation b/w precedence and associativity
-Also, I fail to understand why we have to assign the same
-associativity to operators with the same precedence. For instance,
-why can't I decide that the precedence of * and / is the same, but the
-latter is nonassoc?
-
-If there is really no profound motivation, we should find a new syntax
-to allow specifying this.
-
-** RR conflicts
-See if we can use precedence between rules to solve RR conflicts. See
-what POSIX says.
-
-
-* $undefined
-From Hans:
-- If the Bison generated parser experiences an undefined number in the
-character range, that character is written out in diagnostic messages, an
-addition to the $undefined value.
-
-Suggest: Change the name $undefined to undefined; looks better in outputs.
-
-
-* Default Action
-From Hans:
-- For use with my C++ parser, I transported the "switch (yyn)" statement
-that Bison writes to the bison.simple skeleton file. This way, I can remove
-the current default rule $$ = $1 implementation, which causes a double
-assignment to $$ which may not be OK under C++, replacing it with a
-"default:" part within the switch statement.
-
-Note that the default rule $$ = $1, when typed, is perfectly OK under C,
-but in the C++ implementation I made, this rule is different from
-$<type_name>$ = $<type_name>1. I therefore think that one should implement
-a Bison option where every typed default rule is explicitly written out
-(same typed ruled can of course be grouped together).
-
-Note: Robert Anisko handles this. He knows how to do it.
-
-
-* Warnings
-It would be nice to have warning support. See how Autoconf handles
-them, it is fairly well described there. It would be very nice to
-implement this in such a way that other programs could use
-lib/warnings.[ch].
-
-Don't work on this without first announcing you do, as I already have
-thought about it, and know many of the components that can be used to
-implement it.
-
-
-* Pre and post actions.
-From: Florian Krohm <florian@edamail.fishkill.ibm.com>
-Subject: YYACT_EPILOGUE
-To: bug-bison@gnu.org
-X-Sent: 1 week, 4 days, 14 hours, 38 minutes, 11 seconds ago
-
-The other day I had the need for explicitly building the parse tree. I
-used %locations for that and defined YYLLOC_DEFAULT to call a function
-that returns the tree node for the production. Easy. But I also needed
-to assign the S-attribute to the tree node. That cannot be done in
-YYLLOC_DEFAULT, because it is invoked before the action is executed.
-The way I solved this was to define a macro YYACT_EPILOGUE that would
-be invoked after the action. For reasons of symmetry I also added
-YYACT_PROLOGUE. Although I had no use for that I can envision how it
-might come in handy for debugging purposes.
-All is needed is to add
-
-#if YYLSP_NEEDED
- YYACT_EPILOGUE (yyval, (yyvsp - yylen), yylen, yyloc, (yylsp - yylen));
-#else
- YYACT_EPILOGUE (yyval, (yyvsp - yylen), yylen);
-#endif
-
-at the proper place to bison.simple. Ditto for YYACT_PROLOGUE.
-
-I was wondering what you think about adding YYACT_PROLOGUE/EPILOGUE
-to bison. If you're interested, I'll work on a patch.
-
-* Move to Graphviz
-Well, VCG seems really dead. Move to Graphviz instead. Also, equip
-the parser with a means to create the (visual) parse tree.

-#
-# Of course, Automake must honor this variable whenever it calls a

-# depending on how configure is run. This is pretty annoying, since

-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir

-# harmless because $srcdir is `.', but things will broke when you

-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

-# This will work as long as MISSING is not called from configure, because

-# However there are other variables, like CC, which are often used in

-# AM_PROG_INSTALL_STRIP
-# ---------------------
-# One issue with vendor `install' (even GNU) is that you can't
-# specify the program used to strip binaries. This is especially
-# annoying in cross-compiling environments, where the build's strip
-# is unlikely to handle the host's binaries.
-# Fortunately install-sh will honor a STRIPPROG variable, so we
-# always use install-sh in `make install-strip', and initialize
-# STRIPPROG with the value of the STRIP variable (set by the user).
-AC_DEFUN([AM_PROG_INSTALL_STRIP],

-# Installed binaries are usually stripped using `strip' when the user
-# run `make install-strip'. However `strip' might not be the right
-# tool to use in cross-compilation environments, therefore Automake
-# will honor the `STRIP' environment variable to overrule this program.

-# The first argument passed to this file is the canonical host specification,
-# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
-# or
-# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
-# The environment variables CC, GCC, LDFLAGS, LD, with_gnu_ld

-# The set of defined variables is at the end of this script.
-
-# Known limitations:
-# - On IRIX 6.5 with CC="cc", the run time search patch must not be longer
-# than 256 bytes, otherwise the compiler driver will dump core. The only
-# known workaround is to choose shorter directory names for the build
-# directory and/or the installation directory.
-
-# All known linkers require a `.a' archive for static linking (except MSVC,
-# which needs '.lib').

-% To process a Texinfo manual with TeX, it's most reliable to use the
-% texi2dvi shell script that comes with the distribution. For a simple
-% manual foo.texi, however, you can get away with this:
-% tex foo.texi
-% texindex foo.??
-% tex foo.texi
-% tex foo.texi
-% dvips foo.dvi -o # or whatever; this makes foo.ps.
-% The extra TeX runs get the cross-reference information correct.
-% Sometimes one run after texindex suffices, and sometimes you need more
-% than two; texi2dvi does it as many times as necessary.
-%
-% It is possible to adapt texinfo.tex for other languages, to some
-% extent. You can get the existing language-specific files from the
-% full Texinfo distribution.

-% @multitable macros
-% Amy Hendrickson, 8/18/94, 3/6/96
-%
-% @multitable ... @end multitable will make as many columns as desired.
-% Contents of each column will wrap at width given in preamble. Width
-% can be specified either with sample text given in a template line,
-% or in percent of \hsize, the current width of text on page.
-
-% Table can continue over pages but will only break between lines.
-
-% To make preamble:
-%
-% Either define widths of columns in terms of percent of \hsize:
-% @multitable @columnfractions .25 .3 .45
-% @item ...
-%
-% Numbers following @columnfractions are the percent of the total
-% current hsize to be used for each column. You may use as many
-% columns as desired.
-
-
-% Or use a template:
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item ...
-% using the widest term desired in each column.
-
-% Each new table line starts with @item, each subsequent new column
-% starts with @tab. Empty columns may be produced by supplying @tab's
-% with nothing between them for as many times as empty columns are needed,
-% ie, @tab@tab@tab will produce two empty columns.
-
-% @item, @tab do not need to be on their own lines, but it will not hurt
-% if they are.
-
-% Sample multitable:
-
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item first col stuff @tab second col stuff @tab third col
-% @item
-% first col stuff
-% @tab
-% second col stuff
-% @tab
-% third col
-% @item first col stuff @tab second col stuff
-% @tab Many paragraphs of text may be used in any column.
-%
-% They will wrap at the width determined by the template.
-% @item@tab@tab This will be in third column.
-% @end multitable
-
-% Default dimensions may be reset by user.
-% @multitableparskip is vertical space between paragraphs in table.
-% @multitableparindent is paragraph indent in table.
-% @multitablecolmargin is horizontal space to be left between columns.
-% @multitablelinespace is space to leave between table items, baseline
-% to baseline.
-% 0pt means it depends on current normal line spacing.

-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']

- CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
- headers in a nonstandard directory <include dir>
- CPP C preprocessor
- CXX C++ compiler command
- CXXFLAGS C++ compiler flags

- However, doing the test right would require a run-time
- test, and that would make cross-compilation harder.
- Let us hope that IBM fixes the xlc bug, and also adds
- support for this kind of constant expression. In the
- meantime, this test will reject xlc, which is OK, since
- our stdbool.h substitute should suffice. We also test
- this with GCC, where it should work, to detect more

-This directory contains Bison skeletons: the general shapes of the
-different parser kinds, that are specialized for specific grammars by
-the bison program.
-
-Currently, there are only three supported skeletons:
-
-- yacc.c
- It used to be named bison.simple: it corresponds to C Yacc
- compatible LALR(1) parsers.
-
-- lalr1.cc
- Produces a C++ parser class. It is still very experimental, and not
- yet supported. Please, subscribe to bison-patches@gnu.org.
-
-- glr.c
- A Generalized LR C parser based on Bison's LALR(1) tables.
-
-These skeletons are the only ones supported by the Bison team.
-Because the interface between skeletons and the bison program is not
-finished, *we are not bound to it*. In particular, Bison is not
-mature enough for us to consider that ``foreign skeletons'' are
-supported.

-# This skeleton produces a C++ class that encapsulates a C glr parser.
-# This is in order to reduce the maintenance burden. The glr.c
-# skeleton is clean and pure enough so that there are no real
-# problems. The C++ interface is the same as that of lalr1.cc. In
-# fact, glr.c can replace yacc.c without the user noticing any
-# difference, and similarly for glr.cc replacing lalr1.cc.
-#
-# The passing of parse-params
-#
-# The additional arguments are stored as members of the parser
-# object, yyparser. The C routines need to carry yyparser
-# throughout the C parser; that easy: just let yyparser become an
-# additional parse-param. But because the C++ skeleton needs to
-# know the "real" original parse-param, we save them
-# (b4_parse_param_orig). Note that b4_parse_param is overquoted
-# (and c.m4 strips one level of quotes). This is a PITA, and
-# explains why there are so many levels of quotes.
-#
-# The locations
-#
-# We use location.cc just like lalr1.cc, but because glr.c stores
-# the locations in a (C++) union, the position and location classes
-# must not have a constructor. Therefore, contrary to lalr1.cc, we
-# must not define "b4_location_constructors". As a consequence the
-# user must initialize the first positions (in particular the
-# filename member).

-# Implementing `foreach' loops in m4 is much more tricky than it may
-# seem. Actually, the example of a `foreach' loop in the m4
-# documentation is wrong: it does not quote the arguments properly,
-# which leads to undesirable expansions.
-#
-# The example in the documentation is:
-#
-# | # foreach(VAR, (LIST), STMT)
-# | m4_define([foreach],
-# | [m4_pushdef([$1])_foreach([$1], [$2], [$3])m4_popdef([$1])])

-# | [m4_if([$2], [()], ,
-# | [m4_define([$1], _arg1$2)$3[]_foreach([$1],
-# | (shift$2),
-# | [$3])])])
-#
-# But then if you run
-#
-# | m4_define(a, 1)
-# | m4_define(b, 2)
-# | m4_define(c, 3)
-# | foreach([f], [([a], [(b], [c)])], [echo f
-# | ])
-#
-# it gives
-#
-# => echo 1
-# => echo (2,3)
-#
-# which is not what is expected.
-#
-# Of course the problem is that many quotes are missing. So you add
-# plenty of quotes at random places, until you reach the expected
-# result. Alternatively, if you are a quoting wizard, you directly
-# reach the following implementation (but if you really did, then
-# apply to the maintenance of m4sugar!).
-#
-# | # foreach(VAR, (LIST), STMT)
-# | m4_define([foreach], [m4_pushdef([$1])_foreach($@)m4_popdef([$1])])

-# | [$3])])])
-#
-# which this time answers
-#
-# => echo a
-# => echo (b
-# => echo c)
-#
-# Bingo!
-#
-# Well, not quite.
-#
-# With a better look, you realize that the parens are more a pain than
-# a help: since anyway you need to quote properly the list, you end up
-# with always using an outermost pair of parens and an outermost pair
-# of quotes. Rejecting the parens both eases the implementation, and
-# simplifies the use:
-#
-# | # foreach(VAR, (LIST), STMT)

-## 8. Defining macros with bells and whistles. ##
-## -------------------------------------------- ##
-
-# `m4_defun' is basically `m4_define' but it equips the macro with the
-# needed machinery for `m4_require'. A macro must be m4_defun'd if
-# either it is m4_require'd, or it m4_require's.
-#
-# Two things deserve attention and are detailed below:
-# 1. Implementation of m4_require
-# 2. Keeping track of the expansion stack
-#
-# 1. Implementation of m4_require
-# ===============================
-#
-# Of course m4_defun AC_PROVIDE's the macro, so that a macro which has
-# been expanded is not expanded again when m4_require'd, but the
-# difficult part is the proper expansion of macros when they are
-# m4_require'd.
-#
-# The implementation is based on two ideas, (i) using diversions to
-# prepare the expansion of the macro and its dependencies (by Franc,ois
-# Pinard), and (ii) expand the most recently m4_require'd macros _after_
-# the previous macros (by Axel Thimm).
-#
-#
-# The first idea: why using diversions?
-# -------------------------------------
-#
-# When a macro requires another, the other macro is expanded in new
-# diversion, GROW. When the outer macro is fully expanded, we first
-# undivert the most nested diversions (GROW - 1...), and finally
-# undivert GROW. To understand why we need several diversions,
-# consider the following example:
-#
-# | m4_defun([TEST1], [Test...REQUIRE([TEST2])1])
-# | m4_defun([TEST2], [Test...REQUIRE([TEST3])2])
-# | m4_defun([TEST3], [Test...3])
-#
-# Because m4_require is not required to be first in the outer macros, we
-# must keep the expansions of the various level of m4_require separated.
-# Right before executing the epilogue of TEST1, we have:
-#
-# GROW - 2: Test...3
-# GROW - 1: Test...2
-# GROW: Test...1
-# BODY:
-#
-# Finally the epilogue of TEST1 undiverts GROW - 2, GROW - 1, and
-# GROW into the regular flow, BODY.
-#
-# GROW - 2:
-# GROW - 1:
-# GROW:
-# BODY: Test...3; Test...2; Test...1
-#
-# (The semicolons are here for clarification, but of course are not
-# emitted.) This is what Autoconf 2.0 (I think) to 2.13 (I'm sure)
-# implement.
-#
-#
-# The second idea: first required first out
-# -----------------------------------------
-#
-# The natural implementation of the idea above is buggy and produces
-# very surprising results in some situations. Let's consider the
-# following example to explain the bug:
-#
-# | m4_defun([TEST1], [REQUIRE([TEST2a])REQUIRE([TEST2b])])
-# | m4_defun([TEST2a], [])
-# | m4_defun([TEST2b], [REQUIRE([TEST3])])
-# | m4_defun([TEST3], [REQUIRE([TEST2a])])
-# |
-# | AC_INIT
-# | TEST1
-#
-# The dependencies between the macros are:
-#
-# 3 --- 2b
-# / \ is m4_require'd by
-# / \ left -------------------- right
-# 2a ------------ 1
-#
-# If you strictly apply the rules given in the previous section you get:
-#
-# GROW - 2: TEST3
-# GROW - 1: TEST2a; TEST2b
-# GROW: TEST1
-# BODY:
-#
-# (TEST2a, although required by TEST3 is not expanded in GROW - 3
-# because is has already been expanded before in GROW - 1, so it has
-# been AC_PROVIDE'd, so it is not expanded again) so when you undivert
-# the stack of diversions, you get:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW:
-# BODY: TEST3; TEST2a; TEST2b; TEST1
-#
-# i.e., TEST2a is expanded after TEST3 although the latter required the
-# former.
-#
-# Starting from 2.50, uses an implementation provided by Axel Thimm.
-# The idea is simple: the order in which macros are emitted must be the
-# same as the one in which macro are expanded. (The bug above can
-# indeed be described as: a macro has been AC_PROVIDE'd, but it is
-# emitted after: the lack of correlation between emission and expansion
-# order is guilty).
-#
-# How to do that? You keeping the stack of diversions to elaborate the
-# macros, but each time a macro is fully expanded, emit it immediately.
-#
-# In the example above, when TEST2a is expanded, but it's epilogue is
-# not run yet, you have:
-#
-# GROW - 2:
-# GROW - 1: TEST2a
-# GROW: Elaboration of TEST1
-# BODY:
-#
-# The epilogue of TEST2a emits it immediately:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW: Elaboration of TEST1
-# BODY: TEST2a
-#
-# TEST2b then requires TEST3, so right before the epilogue of TEST3, you
-# have:
-#
-# GROW - 2: TEST3
-# GROW - 1: Elaboration of TEST2b
-# GROW: Elaboration of TEST1
-# BODY: TEST2a
-#
-# The epilogue of TEST3 emits it:
-#
-# GROW - 2:
-# GROW - 1: Elaboration of TEST2b
-# GROW: Elaboration of TEST1
-# BODY: TEST2a; TEST3
-#
-# TEST2b is now completely expanded, and emitted:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW: Elaboration of TEST1
-# BODY: TEST2a; TEST3; TEST2b
-#
-# and finally, TEST1 is finished and emitted:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW:
-# BODY: TEST2a; TEST3; TEST2b: TEST1
-#
-# The idea is simple, but the implementation is a bit evolved. If you
-# are like me, you will want to see the actual functioning of this
-# implementation to be convinced. The next section gives the full
-# details.
-#
-#
-# The Axel Thimm implementation at work
-# -------------------------------------
-#
-# We consider the macros above, and this configure.ac:
-#
-# AC_INIT
-# TEST1
-#
-# You should keep the definitions of _m4_defun_pro, _m4_defun_epi, and
-# m4_require at hand to follow the steps.
-#
-# This implements tries not to assume that the current diversion is
-# BODY, so as soon as a macro (m4_defun'd) is expanded, we first
-# record the current diversion under the name _m4_divert_dump (denoted
-# DUMP below for short). This introduces an important difference with
-# the previous versions of Autoconf: you cannot use m4_require if you
-# are not inside an m4_defun'd macro, and especially, you cannot
-# m4_require directly from the top level.
-#
-# We have not tried to simulate the old behavior (better yet, we
-# diagnose it), because it is too dangerous: a macro m4_require'd from
-# the top level is expanded before the body of `configure', i.e., before
-# any other test was run. I let you imagine the result of requiring
-# AC_STDC_HEADERS for instance, before AC_PROG_CC was actually run....
-#
-# After AC_INIT was run, the current diversion is BODY.
-# * AC_INIT was run
-# DUMP: undefined
-# diversion stack: BODY |-
-#
-# * TEST1 is expanded
-# The prologue of TEST1 sets _m4_divert_dump, which is the diversion
-# where the current elaboration will be dumped, to the current
-# diversion. It also m4_divert_push to GROW, where the full
-# expansion of TEST1 and its dependencies will be elaborated.
-# DUMP: BODY
-# BODY: empty
-# diversions: GROW, BODY |-
-#
-# * TEST1 requires TEST2a
-# _m4_require_call m4_divert_pushes another temporary diversion,
-# GROW - 1, and expands TEST2a in there.
-# DUMP: BODY
-# BODY: empty
-# GROW - 1: TEST2a
-# diversions: GROW - 1, GROW, BODY |-
-# Than the content of the temporary diversion is moved to DUMP and the
-# temporary diversion is popped.
-# DUMP: BODY
-# BODY: TEST2a
-# diversions: GROW, BODY |-
-#
-# * TEST1 requires TEST2b
-# Again, _m4_require_call pushes GROW - 1 and heads to expand TEST2b.
-# DUMP: BODY
-# BODY: TEST2a
-# diversions: GROW - 1, GROW, BODY |-
-#
-# * TEST2b requires TEST3
-# _m4_require_call pushes GROW - 2 and expands TEST3 here.
-# (TEST3 requires TEST2a, but TEST2a has already been m4_provide'd, so
-# nothing happens.)
-# DUMP: BODY
-# BODY: TEST2a
-# GROW - 2: TEST3
-# diversions: GROW - 2, GROW - 1, GROW, BODY |-
-# Than the diversion is appended to DUMP, and popped.
-# DUMP: BODY
-# BODY: TEST2a; TEST3
-# diversions: GROW - 1, GROW, BODY |-
-#
-# * TEST1 requires TEST2b (contd.)
-# The content of TEST2b is expanded...
-# DUMP: BODY
-# BODY: TEST2a; TEST3
-# GROW - 1: TEST2b,
-# diversions: GROW - 1, GROW, BODY |-
-# ... and moved to DUMP.
-# DUMP: BODY
-# BODY: TEST2a; TEST3; TEST2b
-# diversions: GROW, BODY |-
-#
-# * TEST1 is expanded: epilogue
-# TEST1's own content is in GROW...
-# DUMP: BODY
-# BODY: TEST2a; TEST3; TEST2b
-# GROW: TEST1
-# diversions: BODY |-
-# ... and it's epilogue moves it to DUMP and then undefines DUMP.
-# DUMP: undefined
-# BODY: TEST2a; TEST3; TEST2b; TEST1
-# diversions: BODY |-
-#
-#
-# 2. Keeping track of the expansion stack
-# =======================================
-#
-# When M4 expansion goes wrong it is often extremely hard to find the
-# path amongst macros that drove to the failure. What is needed is
-# the stack of macro `calls'. One could imagine that GNU M4 would
-# maintain a stack of macro expansions, unfortunately it doesn't, so
-# we do it by hand. This is of course extremely costly, but the help
-# this stack provides is worth it. Nevertheless to limit the
-# performance penalty this is implemented only for m4_defun'd macros,
-# not for define'd macros.
-#
-# The scheme is simplistic: each time we enter an m4_defun'd macros,
-# we prepend its name in m4_expansion_stack, and when we exit the
-# macro, we remove it (thanks to pushdef/popdef).
-#
-# In addition, we want to detect circular m4_require dependencies.
-# Each time we expand a macro FOO we define _m4_expanding(FOO); and
-# m4_require(BAR) simply checks whether _m4_expanding(BAR) is defined.

-
-1.: DJGPP specific changes.
- =======================
-
- The DJGPP port of Bison offers LFN and SFN support depending on which
- OS it is running. If LFN support is available or not is determinated at
- run time. If LFN support is available (DOS session under Win9X, Win2K,
- WinXP, etc.) the standard posix file name extensions will be used.
- These are: y.tab.c, y.tab.c++, y.tab.h, y.output, etc. If only SFN
- support is available (plain DOS), then the standard MSDOS short file
- names will be used. These are: y_tab.c, y_tab.h, y.out, etc.
- It should be noticed that this bison version needs the m4 program as
- back end to generate the parser file (y.tab.c etc.) from the skeleton
- files. This implies that m4 must always be installed to get bison
- working. m4 will use a couple of m4 scripts that will be installed in
- /dev/env/DJDIR/share/bison and shall not be removed.
- It should also be noticed that the skeleton files bison.simple and
- bison.hairy are no longer supported. This applies also to the environ-
- ment variables BISON_HAIRY and BISON_SIMPLE. Those variables are *no*
- longer honored at all.
- The kind of skeleton file bison.hairy is no longer supported at all.
- The skeleton file bison.simple is now called yacc.c and is an m4 script.
- The other two skeleton files supported by this bison version are glr.c
- and lalr1.cc. The first one is a generalized LR C parser based on
- Bison's LALR(1) tables and the second one is a experimental C++ parser
- class.
- As has been told before, bison uses m4 to generate the parser file.
- This is done by forking and using pipes for the IPC. MSDOS does not
- support this functionality so this has been reproduced in the usual
- way by redirecting stdin and stdout of bison and m4 to temporary files
- and processing these files in sequence. All the changes to the sources
- are documented in the djgpp/diffs file.
-
- Please **read** the docs.
-
-
-2.: Installing the binary package.
- ==============================
-
-2.1.: Copy the binary distribution into the top DJGPP installation directory,
- just unzip it preserving the directory structure running *ONE* of the
- following commands:
- unzip32 bsn@PACKAGE_VERSION@b.zip or
- djtarx bsn@PACKAGE_VERSION@b.zip or
- pkunzip -d bsn@PACKAGE_VERSION@b.zip
-
-
-
-3.: Building the binaries from sources.
- ===================================
-
-3.1.: Create a temporary directory and copy the source package into the
- directory. If you download the source distribution from one of the
- DJGPP sites, just unzip it preserving the directory structure
- running *ONE* of the following commands:
- unzip32 bsn@PACKAGE_VERSION@s.zip or
- djtarx bsn@PACKAGE_VERSION@s.zip or
- pkunzip -d bsn@PACKAGE_VERSION@s.zip
- and proceed to the paragraph 3.3, below.
-
-3.2.: Source distributions downloaded from one of the GNU FTP sites need
- some more work to unpack, if LFN support is not available. If LFN is
- available then you can extract the source files from the archive with
- any unzip program and proceed to the paragraph 3.3, below. Any file
- name issue will be handled by the the DJGPP configuration files.
- To unpack the source distribution on SFN systems, first, you MUST use
- the `djunpack' batch file to unzip the package. That is because some
- file names in the official distributions need to be changed to avoid
- problems on the various platforms supported by DJGPP.
- `djunpack' invokes the `djtar' program (that is part of the basic DJGPP
- development kit) to rename these files on the fly given a file with
- name mappings; the distribution includes a file `djgpp/fnchange.lst'
- with the necessary mappings. So you need first to retrieve that batch
- file, and then invoke it to unpack the distribution. Here's how:
-
- djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@VERSION@.tar.gz > djunpack.bat
- djunpack bison-@VERSION@.tar.gz
-
- (The name of the distribution archive and the leading directory of the
- path to `djunpack.bat' in the distribution will be different for
- versions of Bison other than @VERSION@.)
-
- If the argument to `djunpack.bat' include leading directories, it MUST
- be given with the DOS-style backslashes; Unix-style forward slashes
- will NOT work.
-
- If the distribution comes as a .tar.bz2 archive, and your version of
- `djtar' doesn't support bzip2 decompression, you need to unpack it as
- follows:
-
- bnzip2 bison-@VERSION@.tar.bz2
- djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@VERSION@.tar > djunpack.bat
- djunpack bison-@VERSION@.tar
-
-3.3.: To build the binaries you will need the following binary packages:
- djdev203.zip (or a later but NOT a prior version)
- bsh204b.zip (or a later but NOT a prior version)
- gcc410b.zip, gpp410b.zip, bnu2161b.zip, mak3791b.zip,
- fil40b.zip, shl20jb.zip, txt20b.zip,
- txi48b.zip, grep24b.zip, sed415b.zip,
- m4-144b.zip.
-
- If you want to run the check you will need also:
- dif287b.zip
-
- All this packages can be found in the v2gnu directory of any
- ftp.delorie.com mirror.
- You will need bsh204b.zip or later and *NOT* a prior version or
- the build will fail. The same applies to djdev203.zip. Please note
- that Bison requires m4-144b.zip or later to work properly. All the
- other packages are the ones I have used to build the binaries
- from this source. Previuos versions of this packages may do the
- job as well but I have not tested this.
-
-3.4.: If for some reason you want to reconfigure the package cd into the top
- srcdir (bison-@TREE_VERSION@) and run the following commands:
- del djgpp\config.cache
- make clean
- djgpp\config
-
- Please note that you *MUST* delete the config.cache file in the djgpp
- subdir or you will not really reconfigure the sources because the
- configuration informations will be read from the cache file instead
- of being newly computed.
- To build the programs in a directory other than where the sources are,
- you must add the parameter that specifies the source directory,
- e.g:
- x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@
-
- Lets assume you want to build the binaries in a directory placed on a
- different drive (z:\build in this case) from where the sources are,
- then you will run the following commands:
- z:
- md \build
- cd \build
- x:\src\gnu\bison-@TREE_VERSION@\djgpp\config x:/src/gnu/bison-@TREE_VERSION@
-
- The order of the options and the srcdir option does not matter. You
- *MUST* use forward slashes to specify the source directory.
-
- The batch file will set same environment variables, make MSDOS specific
- modifications to the Makefile.in's and supply all other needed options
- to the configure script.
-
-3.5.: To compile the package run from the top srcdir the command:
- make
-
-3.6.: Now you can run the tests if you like. From the top srcdir run the
- command:
- make check
-
- No test should fail but the tests #131 (Doxygen Public Documentation)
- and #132 (Doxygen Private Documentation) will be skipped. Please note
- that the testsuite only works with LFN available. On plain DOS, most
- of the tests will fail due to invalid DOS names.
-
-3.7.: To install the binaries, header, library, catalogs, and info docs
- run the following command from the top srcdir:
- make install
-
- This will install the products into your DJGPP installation tree given
- by the default prefix "/dev/env/DJDIR". If you prefer to install them
- into some other directory you will have to set prefix to the appropiate
- value:
- make install prefix=z:/some/other/place

- Send GNU bison specific bug reports to <bug-bison@gnu.org>.
- Send suggestions and bug reports concerning the DJGPP port to
- comp.os.msdos.djgpp or <djgpp@delorie.com>.
-
-
-Enjoy.

-.SH DESCRIPTION
-.I Bison
-is a parser generator in the style of
-.IR yacc (1).
-It should be upwardly compatible with input files designed
-for
-.IR yacc .
-.PP
-Input files should follow the
-.I yacc
-convention of ending in
-.BR .y .
-Unlike
-.IR yacc ,
-the generated files do not have fixed names, but instead use the prefix
-of the input file.
-Moreover, if you need to put
-.I C++
-code in the input file, you can end his name by a C++-like extension
-(.ypp or .y++), then bison will follow your extension to name the
-output file (.cpp or .c++).
-For instance, a grammar description file named
-.B parse.yxx
-would produce the generated parser in a file named
-.BR parse.tab.cxx ,
-instead of
-.IR yacc 's
-.B y.tab.c
-or old
-.I Bison
-version's
-.BR parse.tab.c .
-.PP
-This description of the options that can be given to
-.I bison
-is adapted from the node
-.B Invocation
-in the
-.B bison.texinfo
-manual, which should be taken as authoritative.
-.PP
-.I Bison
-supports both traditional single-letter options and mnemonic long
-option names. Long option names are indicated with
-.B \-\-
-instead of
-.BR \- .
-Abbreviations for option names are allowed as long as they
-are unique. When a long option takes an argument, like
-.BR \-\-file-prefix ,
-connect the option name and the argument with
-.BR = .
-.SS OPTIONS
-.TP
-.BI \-b " file-prefix"
-.br
-.ns
-.TP
-.BI \-\-file-prefix= file-prefix
-Specify a prefix to use for all
-.I bison
-output file names. The names are
-chosen as if the input file were named
-\fIfile-prefix\fP\fB.c\fP.
-.TP
-.B \-d
-.br
-.ns
-Write an extra output file containing macro definitions for the token
-type names defined in the grammar and the semantic value type
-.BR YYSTYPE ,
-as well as a few
-.B extern
-variable declarations.
-.sp
-If the parser output file is named
-.IB name .c
-then this file
-is named
-\fIname\fP\fB.h\fP.
-.sp
-This output file is essential if you wish to put the definition of
-.B yylex
-in a separate source file, because
-.B yylex
-needs to be able to refer to token type codes and the variable
-.BR yylval .
-.TP
-.BI \-\-defines= defines-file
-The behavior of
-.B \-\-defines
-is the same than
-.B \-d
-option.
-The only difference is that it has an optional argument which is
-the name of the output filename.
-.TP
-.BI \-g
-.br
-.ns
-Output a VCG definition of the LALR(1) grammar automaton computed by
-Bison. If the grammar file is
-.BR foo.y
-, the VCG output file will be
-.BR foo.vcg .
-.TP
-.BI \-\-graph= graph-file
-The behavior of
-.BI \-\-graph
-is the same than
-.BI \-g
-option. The only difference is that it has an optional argument which
-is the name of the output graph filename.
-.TP
-.B \-k
-.br
-.ns
-.TP
-.B \-\-token-table
-This switch causes the
-.IB name .tab.c
-output to include a list of
-token names in order by their token numbers; this is defined in the array
-.IR yytname .
-Also generated
-are #defines for
-.IR YYNTOKENS ,
-.IR YYNNTS ,
-.IR YYNRULES ,
-and
-.IR YYNSTATES .
-.TP
-.B \-l
-.br
-.ns
-.TP
-.B \-\-no-lines
-Don't put any
-.B #line
-preprocessor commands in the parser file.
-Ordinarily
-.I bison
-puts them in the parser file so that the C compiler
-and debuggers will associate errors with your source file, the
-grammar file. This option causes them to associate errors with the
-parser file, treating it an independent source file in its own right.
-.TP
-.B \-n
-.br
-.ns
-.TP
-.B \-\-no-parser
-Do not generate the parser code into the output; generate only
-declarations. The generated
-.IB name .tab.c
-file will have only
-constant declarations. In addition, a
-.IB name .act
-file is
-generated containing a switch statement body containing all the
-translated actions.
-.TP
-.BI \-o " outfile"
-.br
-.ns
-.TP
-.BI \-\-output-file= outfile
-Specify the name
-.I outfile
-for the parser file.
-.sp
-The other output files' names are constructed from
-.I outfile
-as described under the
-.B \-v
-and
-.B \-d
-switches.
-.TP
-.BI \-p " prefix"
-.br
-.ns
-.TP
-.BI \-\-name-prefix= prefix
-Rename the external symbols used in the parser so that they start with
-.I prefix
-instead of
-.BR yy .
-The precise list of symbols renamed is
-.BR yyparse ,
-.BR yylex ,
-.BR yyerror ,
-.BR yylval ,
-.BR yychar ,
-and
-.BR yydebug .
-.sp
-For example, if you use
-.BR "\-p c" ,
-the names become
-.BR cparse ,
-.BR clex ,
-and so on.
-.TP
-.B \-t
-.br
-.ns
-.TP
-.B \-\-debug
-In the parser file, define the macro
-.B YYDEBUG
-to 1 if it is not already defined,
-so that the debugging facilities are compiled.
-.TP
-.B \-v
-.br
-.ns
-.TP
-.B \-\-verbose
-Write an extra output file containing verbose descriptions of the
-parser states and what is done for each type of look-ahead token in
-that state.
-.sp
-This file also describes all the conflicts, both those resolved by
-operator precedence and the unresolved ones.
-.sp
-The file's name is made by removing
-.B .tab.c
-or
-.B .c
-from the parser output file name, and adding
-.B .output
-instead.
-.sp
-Therefore, if the input file is
-.BR foo.y ,
-then the parser file is called
-.B foo.tab.c
-by default. As a consequence, the verbose
-output file is called
-.BR foo.output .
-.TP
-.B \-V
-.br
-.ns
-.TP
-.B \-\-version
-Print the version number of
-.I bison
-and exit.
-.TP
-.B \-h
-.br
-.ns
-.TP
-.B \-\-help
-Print a summary of the options to
-.I bison
-and exit.
-.TP
-.B \-y
-.br
-.ns
-.TP
-.B \-\-yacc
-.br
-.ns
-.TP
-.B \-\-fixed-output-files
-Equivalent to
-.BR "\-o y.tab.c" ;
-the parser output file is called
-.BR y.tab.c ,
-and the other outputs are called
-.B y.output
-and
-.BR y.tab.h .
-The purpose of this switch is to imitate
-.IR yacc 's
-output file name conventions.
-Thus, the following shell script can substitute for
-.I yacc
-and is often installed as
-.IR yacc :
-.sp
-.RS
-.ft B
-bison \-y "$@"
-.ft R
-.sp

-.SH SEE ALSO
-.IR yacc (1)
-.br
-The
-.IR "Bison Reference Manual" ,
-included as the file
-.B bison.texinfo
-in the
-.I bison
-source distribution.
-.SH DIAGNOSTICS
-Self explanatory.

-@node Introduction
-@unnumbered Introduction
-@cindex introduction
-
-@dfn{Bison} is a general-purpose parser generator that converts an
-annotated context-free grammar into an @acronym{LALR}(1) or
-@acronym{GLR} parser for that grammar. Once you are proficient with
-Bison, you can use it to develop a wide range of language parsers, from those
-used in simple desk calculators to complex programming languages.
-
-Bison is upward compatible with Yacc: all properly-written Yacc grammars
-ought to work with Bison with no change. Anyone familiar with Yacc
-should be able to use Bison with little trouble. You need to be fluent in
-C or C++ programming in order to use Bison or to understand this manual.
-
-We begin with tutorial chapters that explain the basic concepts of using
-Bison and show three explained examples, each building on the last. If you
-don't know Bison or Yacc, start by reading these chapters. Reference
-chapters follow which describe specific aspects of Bison in detail.
-
-Bison was written primarily by Robert Corbett; Richard Stallman made it
-Yacc-compatible. Wilfred Hansen of Carnegie Mellon University added
-multi-character string literals and other features.
-
-This edition corresponds to version @value{VERSION} of Bison.
-
-@node Conditions
-@unnumbered Conditions for Using Bison
-
-The distribution terms for Bison-generated parsers permit using the
-parsers in nonfree programs. Before Bison version 2.2, these extra
-permissions applied only when Bison was generating @acronym{LALR}(1)
-parsers in C@. And before Bison version 1.24, Bison-generated
-parsers could be used only in programs that were free software.
-
-The other @acronym{GNU} programming tools, such as the @acronym{GNU} C
-compiler, have never
-had such a requirement. They could always be used for nonfree
-software. The reason Bison was different was not due to a special
-policy decision; it resulted from applying the usual General Public
-License to all of the Bison source code.
-
-The output of the Bison utility---the Bison parser file---contains a
-verbatim copy of a sizable piece of Bison, which is the code for the
-parser's implementation. (The actions from your grammar are inserted
-into this implementation at one point, but most of the rest of the
-implementation is not changed.) When we applied the @acronym{GPL}
-terms to the skeleton code for the parser's implementation,
-the effect was to restrict the use of Bison output to free software.
-
-We didn't change the terms because of sympathy for people who want to
-make software proprietary. @strong{Software should be free.} But we
-concluded that limiting Bison's use to free software was doing little to
-encourage people to make other software free. So we decided to make the
-practical conditions for using Bison match the practical conditions for
-using the other @acronym{GNU} tools.
-
-This exception applies when Bison is generating code for a parser.
-You can tell whether the exception applies to a Bison output file by
-inspecting the file for text beginning with ``As a special
-exception@dots{}''. The text spells out the exact terms of the
-exception.

-@node Language and Grammar
-@section Languages and Context-Free Grammars
-
-@cindex context-free grammar
-@cindex grammar, context-free
-In order for Bison to parse a language, it must be described by a
-@dfn{context-free grammar}. This means that you specify one or more
-@dfn{syntactic groupings} and give rules for constructing them from their
-parts. For example, in the C language, one kind of grouping is called an
-`expression'. One rule for making an expression might be, ``An expression
-can be made of a minus sign and another expression''. Another would be,
-``An expression can be an integer''. As you can see, rules are often
-recursive, but there must be at least one rule which leads out of the
-recursion.
-
-@cindex @acronym{BNF}
-@cindex Backus-Naur form
-The most common formal system for presenting such rules for humans to read
-is @dfn{Backus-Naur Form} or ``@acronym{BNF}'', which was developed in
-order to specify the language Algol 60. Any grammar expressed in
-@acronym{BNF} is a context-free grammar. The input to Bison is
-essentially machine-readable @acronym{BNF}.
-
-@cindex @acronym{LALR}(1) grammars
-@cindex @acronym{LR}(1) grammars
-There are various important subclasses of context-free grammar. Although it
-can handle almost all context-free grammars, Bison is optimized for what
-are called @acronym{LALR}(1) grammars.
-In brief, in these grammars, it must be possible to
-tell how to parse any portion of an input string with just a single
-token of look-ahead. Strictly speaking, that is a description of an
-@acronym{LR}(1) grammar, and @acronym{LALR}(1) involves additional
-restrictions that are
-hard to explain simply; but it is rare in actual practice to find an
-@acronym{LR}(1) grammar that fails to be @acronym{LALR}(1).
-@xref{Mystery Conflicts, ,Mysterious Reduce/Reduce Conflicts}, for
-more information on this.
-
-@cindex @acronym{GLR} parsing
-@cindex generalized @acronym{LR} (@acronym{GLR}) parsing
-@cindex ambiguous grammars
-@cindex nondeterministic parsing
-
-Parsers for @acronym{LALR}(1) grammars are @dfn{deterministic}, meaning
-roughly that the next grammar rule to apply at any point in the input is
-uniquely determined by the preceding input and a fixed, finite portion
-(called a @dfn{look-ahead}) of the remaining input. A context-free
-grammar can be @dfn{ambiguous}, meaning that there are multiple ways to
-apply the grammar rules to get the same inputs. Even unambiguous
-grammars can be @dfn{nondeterministic}, meaning that no fixed
-look-ahead always suffices to determine the next grammar rule to apply.
-With the proper declarations, Bison is also able to parse these more
-general context-free grammars, using a technique known as @acronym{GLR}
-parsing (for Generalized @acronym{LR}). Bison's @acronym{GLR} parsers
-are able to handle any context-free grammar for which the number of
-possible parses of any given string is finite.
-
-@cindex symbols (abstract)
-@cindex token
-@cindex syntactic grouping
-@cindex grouping, syntactic
-In the formal grammatical rules for a language, each kind of syntactic
-unit or grouping is named by a @dfn{symbol}. Those which are built by
-grouping smaller constructs according to grammatical rules are called
-@dfn{nonterminal symbols}; those which can't be subdivided are called
-@dfn{terminal symbols} or @dfn{token types}. We call a piece of input
-corresponding to a single terminal symbol a @dfn{token}, and a piece
-corresponding to a single nonterminal symbol a @dfn{grouping}.
-
-We can use the C language as an example of what symbols, terminal and
-nonterminal, mean. The tokens of C are identifiers, constants (numeric
-and string), and the various keywords, arithmetic operators and
-punctuation marks. So the terminal symbols of a grammar for C include
-`identifier', `number', `string', plus one symbol for each keyword,
-operator or punctuation mark: `if', `return', `const', `static', `int',
-`char', `plus-sign', `open-brace', `close-brace', `comma' and many more.
-(These tokens can be subdivided into characters, but that is a matter of
-lexicography, not grammar.)
-
-Here is a simple C function subdivided into tokens:
-
-@ifinfo
-@example
-int /* @r{keyword `int'} */
-square (int x) /* @r{identifier, open-paren, keyword `int',}
- @r{identifier, close-paren} */
-@{ /* @r{open-brace} */
- return x * x; /* @r{keyword `return', identifier, asterisk,}
- @r{identifier, semicolon} */
-@} /* @r{close-brace} */
-@end example
-@end ifinfo
-@ifnotinfo
-@example
-int /* @r{keyword `int'} */
-square (int x) /* @r{identifier, open-paren, keyword `int', identifier, close-paren} */
-@{ /* @r{open-brace} */
- return x * x; /* @r{keyword `return', identifier, asterisk, identifier, semicolon} */
-@} /* @r{close-brace} */
-@end example
-@end ifnotinfo
-
-The syntactic groupings of C include the expression, the statement, the
-declaration, and the function definition. These are represented in the
-grammar of C by nonterminal symbols `expression', `statement',
-`declaration' and `function definition'. The full grammar uses dozens of
-additional language constructs, each with its own nonterminal symbol, in
-order to express the meanings of these four. The example above is a
-function definition; it contains one declaration, and one statement. In
-the statement, each @samp{x} is an expression and so is @samp{x * x}.
-
-Each nonterminal symbol must have grammatical rules showing how it is made
-out of simpler constructs. For example, one kind of C statement is the
-@code{return} statement; this would be described with a grammar rule which
-reads informally as follows:
-
-@quotation
-A `statement' can be made of a `return' keyword, an `expression' and a
-`semicolon'.
-@end quotation
-
-@noindent
-There would be many other rules for `statement', one for each kind of
-statement in C.
-
-@cindex start symbol
-One nonterminal symbol must be distinguished as the special one which
-defines a complete utterance in the language. It is called the @dfn{start
-symbol}. In a compiler, this means a complete input program. In the C
-language, the nonterminal symbol `sequence of definitions and declarations'
-plays this role.
-
-For example, @samp{1 + 2} is a valid C expression---a valid part of a C
-program---but it is not valid as an @emph{entire} C program. In the
-context-free grammar of C, this follows from the fact that `expression' is
-not the start symbol.
-
-The Bison parser reads a sequence of tokens as its input, and groups the
-tokens using the grammar rules. If the input is valid, the end result is
-that the entire token sequence reduces to a single grouping whose symbol is
-the grammar's start symbol. If we use a grammar for C, the entire input
-must be a `sequence of definitions and declarations'. If not, the parser
-reports a syntax error.
-
-@node Grammar in Bison
-@section From Formal Rules to Bison Input
-@cindex Bison grammar
-@cindex grammar, Bison
-@cindex formal grammar
-
-A formal grammar is a mathematical construct. To define the language
-for Bison, you must write a file expressing the grammar in Bison syntax:
-a @dfn{Bison grammar} file. @xref{Grammar File, ,Bison Grammar Files}.
-
-A nonterminal symbol in the formal grammar is represented in Bison input
-as an identifier, like an identifier in C@. By convention, it should be
-in lower case, such as @code{expr}, @code{stmt} or @code{declaration}.
-
-The Bison representation for a terminal symbol is also called a @dfn{token
-type}. Token types as well can be represented as C-like identifiers. By
-convention, these identifiers should be upper case to distinguish them from
-nonterminals: for example, @code{INTEGER}, @code{IDENTIFIER}, @code{IF} or
-@code{RETURN}. A terminal symbol that stands for a particular keyword in
-the language should be named after that keyword converted to upper case.
-The terminal symbol @code{error} is reserved for error recovery.
-@xref{Symbols}.
-
-A terminal symbol can also be represented as a character literal, just like
-a C character constant. You should do this whenever a token is just a
-single character (parenthesis, plus-sign, etc.): use that same character in
-a literal as the terminal symbol for that token.
-
-A third way to represent a terminal symbol is with a C string constant
-containing several characters. @xref{Symbols}, for more information.
-
-The grammar rules also have an expression in Bison syntax. For example,
-here is the Bison rule for a C @code{return} statement. The semicolon in
-quotes is a literal character token, representing part of the C syntax for
-the statement; the naked semicolon, and the colon, are Bison punctuation
-used in every rule.
-
-@example
-stmt: RETURN expr ';'
- ;
-@end example
-
-@noindent
-@xref{Rules, ,Syntax of Grammar Rules}.
-
-@node Semantic Values
-@section Semantic Values
-@cindex semantic value
-@cindex value, semantic
-
-A formal grammar selects tokens only by their classifications: for example,
-if a rule mentions the terminal symbol `integer constant', it means that
-@emph{any} integer constant is grammatically valid in that position. The
-precise value of the constant is irrelevant to how to parse the input: if
-@samp{x+4} is grammatical then @samp{x+1} or @samp{x+3989} is equally
-grammatical.
-
-But the precise value is very important for what the input means once it is
-parsed. A compiler is useless if it fails to distinguish between 4, 1 and
-3989 as constants in the program! Therefore, each token in a Bison grammar
-has both a token type and a @dfn{semantic value}. @xref{Semantics,
-,Defining Language Semantics},
-for details.
-
-The token type is a terminal symbol defined in the grammar, such as
-@code{INTEGER}, @code{IDENTIFIER} or @code{','}. It tells everything
-you need to know to decide where the token may validly appear and how to
-group it with other tokens. The grammar rules know nothing about tokens
-except their types.
-
-The semantic value has all the rest of the information about the
-meaning of the token, such as the value of an integer, or the name of an
-identifier. (A token such as @code{','} which is just punctuation doesn't
-need to have any semantic value.)
-
-For example, an input token might be classified as token type
-@code{INTEGER} and have the semantic value 4. Another input token might
-have the same token type @code{INTEGER} but value 3989. When a grammar
-rule says that @code{INTEGER} is allowed, either of these tokens is
-acceptable because each is an @code{INTEGER}. When the parser accepts the
-token, it keeps track of the token's semantic value.
-
-Each grouping can also have a semantic value as well as its nonterminal
-symbol. For example, in a calculator, an expression typically has a
-semantic value that is a number. In a compiler for a programming
-language, an expression typically has a semantic value that is a tree
-structure describing the meaning of the expression.
-
-@node Semantic Actions
-@section Semantic Actions
-@cindex semantic actions
-@cindex actions, semantic
-
-In order to be useful, a program must do more than parse input; it must
-also produce some output based on the input. In a Bison grammar, a grammar
-rule can have an @dfn{action} made up of C statements. Each time the
-parser recognizes a match for that rule, the action is executed.
-@xref{Actions}.
-
-Most of the time, the purpose of an action is to compute the semantic value
-of the whole construct from the semantic values of its parts. For example,
-suppose we have a rule which says an expression can be the sum of two
-expressions. When the parser recognizes such a sum, each of the
-subexpressions has a semantic value which describes how it was built up.
-The action for this rule should create a similar sort of value for the
-newly recognized larger expression.
-
-For example, here is a rule that says an expression can be the sum of
-two subexpressions:
-
-@example
-expr: expr '+' expr @{ $$ = $1 + $3; @}
- ;
-@end example
-
-@noindent
-The action says how to produce the semantic value of the sum expression
-from the values of the two subexpressions.

-@findex %glr-parser
-@cindex conflicts
-@cindex shift/reduce conflicts
-@cindex reduce/reduce conflicts
-
-In some grammars, Bison's standard
-@acronym{LALR}(1) parsing algorithm cannot decide whether to apply a
-certain grammar rule at a given point. That is, it may not be able to
-decide (on the basis of the input read so far) which of two possible
-reductions (applications of a grammar rule) applies, or whether to apply
-a reduction or read more of the input and apply a reduction later in the
-input. These are known respectively as @dfn{reduce/reduce} conflicts
-(@pxref{Reduce/Reduce}), and @dfn{shift/reduce} conflicts
-(@pxref{Shift/Reduce}).
-
-To use a grammar that is not easily modified to be @acronym{LALR}(1), a
-more general parsing algorithm is sometimes necessary. If you include
-@code{%glr-parser} among the Bison declarations in your file
-(@pxref{Grammar Outline}), the result is a Generalized @acronym{LR}
-(@acronym{GLR}) parser. These parsers handle Bison grammars that
-contain no unresolved conflicts (i.e., after applying precedence
-declarations) identically to @acronym{LALR}(1) parsers. However, when
-faced with unresolved shift/reduce and reduce/reduce conflicts,
-@acronym{GLR} parsers use the simple expedient of doing both,
-effectively cloning the parser to follow both possibilities. Each of
-the resulting parsers can again split, so that at any given time, there
-can be any number of possible parses being explored. The parsers
-proceed in lockstep; that is, all of them consume (shift) a given input
-symbol before any of them proceed to the next. Each of the cloned
-parsers eventually meets one of two possible fates: either it runs into
-a parsing error, in which case it simply vanishes, or it merges with
-another parser, because the two of them have reduced the input to an
-identical set of symbols.
-
-During the time that there are multiple parsers, semantic actions are
-recorded, but not performed. When a parser disappears, its recorded
-semantic actions disappear as well, and are never performed. When a
-reduction makes two parsers identical, causing them to merge, Bison
-records both sets of semantic actions. Whenever the last two parsers
-merge, reverting to the single-parser case, Bison resolves all the
-outstanding actions either by precedences given to the grammar rules
-involved, or by performing both actions, and then calling a designated
-user-defined function on the resulting values to produce an arbitrary
-merged result.

-
-In the simplest cases, you can use the @acronym{GLR} algorithm
-to parse grammars that are unambiguous, but fail to be @acronym{LALR}(1).
-Such grammars typically require more than one symbol of look-ahead,
-or (in rare cases) fall into the category of grammars in which the
-@acronym{LALR}(1) algorithm throws away too much information (they are in
-@acronym{LR}(1), but not @acronym{LALR}(1), @ref{Mystery Conflicts}).
-
-Consider a problem that
-arises in the declaration of enumerated and subrange types in the
-programming language Pascal. Here are some examples:
-
-@example
-type subrange = lo .. hi;
-type enum = (a, b, c);
-@end example
-
-@noindent
-The original language standard allows only numeric
-literals and constant identifiers for the subrange bounds (@samp{lo}
-and @samp{hi}), but Extended Pascal (@acronym{ISO}/@acronym{IEC}
-10206) and many other
-Pascal implementations allow arbitrary expressions there. This gives
-rise to the following situation, containing a superfluous pair of
-parentheses:
-
-@example
-type subrange = (a) .. b;
-@end example
-
-@noindent
-Compare this to the following declaration of an enumerated
-type with only one value:
-
-@example
-type enum = (a);
-@end example
-
-@noindent
-(These declarations are contrived, but they are syntactically
-valid, and more-complicated cases can come up in practical programs.)
-
-These two declarations look identical until the @samp{..} token.
-With normal @acronym{LALR}(1) one-token look-ahead it is not
-possible to decide between the two forms when the identifier
-@samp{a} is parsed. It is, however, desirable
-for a parser to decide this, since in the latter case
-@samp{a} must become a new identifier to represent the enumeration
-value, while in the former case @samp{a} must be evaluated with its
-current meaning, which may be a constant or even a function call.
-
-You could parse @samp{(a)} as an ``unspecified identifier in parentheses'',
-to be resolved later, but this typically requires substantial
-contortions in both semantic actions and large parts of the
-grammar, where the parentheses are nested in the recursive rules for
-expressions.
-
-You might think of using the lexer to distinguish between the two
-forms by returning different tokens for currently defined and
-undefined identifiers. But if these declarations occur in a local
-scope, and @samp{a} is defined in an outer scope, then both forms
-are possible---either locally redefining @samp{a}, or using the
-value of @samp{a} from the outer scope. So this approach cannot
-work.
-
-A simple solution to this problem is to declare the parser to
-use the @acronym{GLR} algorithm.
-When the @acronym{GLR} parser reaches the critical state, it
-merely splits into two branches and pursues both syntax rules
-simultaneously. Sooner or later, one of them runs into a parsing
-error. If there is a @samp{..} token before the next
-@samp{;}, the rule for enumerated types fails since it cannot
-accept @samp{..} anywhere; otherwise, the subrange type rule
-fails since it requires a @samp{..} token. So one of the branches
-fails silently, and the other one continues normally, performing
-all the intermediate actions that were postponed during the split.
-
-If the input is syntactically incorrect, both branches fail and the parser
-reports a syntax error as usual.
-
-The effect of all this is that the parser seems to ``guess'' the
-correct branch to take, or in other words, it seems to use more
-look-ahead than the underlying @acronym{LALR}(1) algorithm actually allows
-for. In this example, @acronym{LALR}(2) would suffice, but also some cases
-that are not @acronym{LALR}(@math{k}) for any @math{k} can be handled this way.
-
-In general, a @acronym{GLR} parser can take quadratic or cubic worst-case time,
-and the current Bison parser even takes exponential time and space
-for some grammars. In practice, this rarely happens, and for many
-grammars it is possible to prove that it cannot happen.
-The present example contains only one conflict between two
-rules, and the type-declaration context containing the conflict
-cannot be nested. So the number of
-branches that can exist at any time is limited by the constant 2,
-and the parsing time is still linear.
-
-Here is a Bison grammar corresponding to the example above. It
-parses a vastly simplified form of Pascal type declarations.
-
-@example
-%token TYPE DOTDOT ID
-
-@group
-%left '+' '-'
-%left '*' '/'
-@end group
-
-%%
-
-@group
-type_decl : TYPE ID '=' type ';'
- ;
-@end group
-
-@group
-type : '(' id_list ')'
- | expr DOTDOT expr
- ;
-@end group
-
-@group
-id_list : ID
- | id_list ',' ID
- ;
-@end group
-
-@group
-expr : '(' expr ')'
- | expr '+' expr
- | expr '-' expr
- | expr '*' expr
- | expr '/' expr
- | ID
- ;
-@end group
-@end example
-
-When used as a normal @acronym{LALR}(1) grammar, Bison correctly complains
-about one reduce/reduce conflict. In the conflicting situation the
-parser chooses one of the alternatives, arbitrarily the one
-declared first. Therefore the following correct input is not
-recognized:
-
-@example
-type t = (a) .. b;
-@end example
-
-The parser can be turned into a @acronym{GLR} parser, while also telling Bison
-to be silent about the one known reduce/reduce conflict, by
-adding these two declarations to the Bison input file (before the first
-@samp{%%}):
-
-@example
-%glr-parser
-%expect-rr 1
-@end example
-
-@noindent
-No change in the grammar itself is required. Now the
-parser recognizes all valid declarations, according to the
-limited syntax above, transparently. In fact, the user does not even
-notice when the parser splits.
-
-So here we have a case where we can use the benefits of @acronym{GLR},
-almost without disadvantages. Even in simple cases like this, however,
-there are at least two potential problems to beware. First, always
-analyze the conflicts reported by Bison to make sure that @acronym{GLR}
-splitting is only done where it is intended. A @acronym{GLR} parser
-splitting inadvertently may cause problems less obvious than an
-@acronym{LALR} parser statically choosing the wrong alternative in a
-conflict. Second, consider interactions with the lexer (@pxref{Semantic
-Tokens}) with great care. Since a split parser consumes tokens without
-performing any actions during the split, the lexer cannot obtain
-information via parser actions. Some cases of lexer interactions can be
-eliminated by using @acronym{GLR} to shift the complications from the
-lexer to the parser. You must check the remaining cases for
-correctness.
-
-In our example, it would be safe for the lexer to return tokens based on
-their current meanings in some symbol table, because no new symbols are
-defined in the middle of a type declaration. Though it is possible for
-a parser to define the enumeration constants as they are parsed, before
-the type declaration is completed, it actually makes no difference since
-they cannot be used within the same enumerated type declaration.

-
-Let's consider an example, vastly simplified from a C++ grammar.
-
-@example
-%@{
- #include <stdio.h>
- #define YYSTYPE char const *
- int yylex (void);
- void yyerror (char const *);
-%@}
-
-%token TYPENAME ID

- | TYPENAME '(' expr ')'
- @{ printf ("%s <cast> ", $1); @}
- | expr '+' expr @{ printf ("+ "); @}
- | expr '=' expr @{ printf ("= "); @}

-
-decl : TYPENAME declarator ';'
- @{ printf ("%s <declare> ", $1); @}
- | TYPENAME declarator '=' expr ';'
- @{ printf ("%s <init-declare> ", $1); @}
- ;
-
-declarator : ID @{ printf ("\"%s\" ", $1); @}
- | '(' declarator ')'
- ;
-@end example
-
-@noindent
-This models a problematic part of the C++ grammar---the ambiguity between
-certain declarations and statements. For example,
-
-@example
-T (x) = y+z;
-@end example
-
-@noindent
-parses as either an @code{expr} or a @code{stmt}
-(assuming that @samp{T} is recognized as a @code{TYPENAME} and
-@samp{x} as an @code{ID}).
-Bison detects this as a reduce/reduce conflict between the rules
-@code{expr : ID} and @code{declarator : ID}, which it cannot resolve at the
-time it encounters @code{x} in the example above. Since this is a
-@acronym{GLR} parser, it therefore splits the problem into two parses, one for
-each choice of resolving the reduce/reduce conflict.
-Unlike the example from the previous section (@pxref{Simple GLR Parsers}),
-however, neither of these parses ``dies,'' because the grammar as it stands is
-ambiguous. One of the parsers eventually reduces @code{stmt : expr ';'} and
-the other reduces @code{stmt : decl}, after which both parsers are in an
-identical state: they've seen @samp{prog stmt} and have the same unprocessed
-input remaining. We say that these parses have @dfn{merged.}
-
-At this point, the @acronym{GLR} parser requires a specification in the
-grammar of how to choose between the competing parses.
-In the example above, the two @code{%dprec}
-declarations specify that Bison is to give precedence
-to the parse that interprets the example as a
-@code{decl}, which implies that @code{x} is a declarator.
-The parser therefore prints
-
-@example
-"x" y z + T <init-declare>
-@end example
-
-The @code{%dprec} declarations only come into play when more than one
-parse survives. Consider a different input string for this parser:
-
-@example
-T (x) + y;
-@end example
-
-@noindent
-This is another example of using @acronym{GLR} to parse an unambiguous
-construct, as shown in the previous section (@pxref{Simple GLR Parsers}).
-Here, there is no ambiguity (this cannot be parsed as a declaration).
-However, at the time the Bison parser encounters @code{x}, it does not
-have enough information to resolve the reduce/reduce conflict (again,
-between @code{x} as an @code{expr} or a @code{declarator}). In this
-case, no precedence declaration is used. Again, the parser splits
-into two, one assuming that @code{x} is an @code{expr}, and the other
-assuming @code{x} is a @code{declarator}. The second of these parsers
-then vanishes when it sees @code{+}, and the parser prints
-
-@example
-x T <cast> y +
-@end example
-
-Suppose that instead of resolving the ambiguity, you wanted to see all
-the possibilities. For this purpose, you must merge the semantic
-actions of the two possible parsers, rather than choosing one over the
-other. To do so, you could change the declaration of @code{stmt} as
-follows:
-
-@example
-stmt : expr ';' %merge <stmtMerge>
- | decl %merge <stmtMerge>
- ;
-@end example
-
-@noindent
-and define the @code{stmtMerge} function as:
-
-@example
-static YYSTYPE
-stmtMerge (YYSTYPE x0, YYSTYPE x1)
-@{
- printf ("<OR> ");
- return "";
-@}
-@end example
-
-@noindent
-with an accompanying forward declaration
-in the C declarations at the beginning of the file:
-
-@example
-%@{
- #define YYSTYPE char const *
- static YYSTYPE stmtMerge (YYSTYPE x0, YYSTYPE x1);
-%@}
-@end example
-
-@noindent
-With these declarations, the resulting parser parses the first example
-as both an @code{expr} and a @code{decl}, and prints
-
-@example
-"x" y z + T <init-declare> x T <cast> y z + = <OR>
-@end example
-
-Bison requires that all of the
-productions that participate in any particular merge have identical
-@samp{%merge} clauses. Otherwise, the ambiguity would be unresolvable,
-and the parser will report an error during any parse that results in
-the offending merge.
-
-@node GLR Semantic Actions
-@subsection GLR Semantic Actions
-
-@cindex deferred semantic actions
-By definition, a deferred semantic action is not performed at the same time as
-the associated reduction.
-This raises caveats for several Bison features you might use in a semantic
-action in a @acronym{GLR} parser.
-
-@vindex yychar
-@cindex @acronym{GLR} parsers and @code{yychar}
-@vindex yylval
-@cindex @acronym{GLR} parsers and @code{yylval}
-@vindex yylloc
-@cindex @acronym{GLR} parsers and @code{yylloc}
-In any semantic action, you can examine @code{yychar} to determine the type of
-the look-ahead token present at the time of the associated reduction.
-After checking that @code{yychar} is not set to @code{YYEMPTY} or @code{YYEOF},
-you can then examine @code{yylval} and @code{yylloc} to determine the
-look-ahead token's semantic value and location, if any.
-In a nondeferred semantic action, you can also modify any of these variables to
-influence syntax analysis.
-@xref{Look-Ahead, ,Look-Ahead Tokens}.
-
-@findex yyclearin
-@cindex @acronym{GLR} parsers and @code{yyclearin}
-In a deferred semantic action, it's too late to influence syntax analysis.
-In this case, @code{yychar}, @code{yylval}, and @code{yylloc} are set to
-shallow copies of the values they had at the time of the associated reduction.
-For this reason alone, modifying them is dangerous.
-Moreover, the result of modifying them is undefined and subject to change with
-future versions of Bison.
-For example, if a semantic action might be deferred, you should never write it
-to invoke @code{yyclearin} (@pxref{Action Features}) or to attempt to free
-memory referenced by @code{yylval}.
-
-@findex YYERROR
-@cindex @acronym{GLR} parsers and @code{YYERROR}
-Another Bison feature requiring special consideration is @code{YYERROR}
-(@pxref{Action Features}), which you can invoke in a semantic action to
-initiate error recovery.
-During deterministic @acronym{GLR} operation, the effect of @code{YYERROR} is
-the same as its effect in an @acronym{LALR}(1) parser.
-In a deferred semantic action, its effect is undefined.
-@c The effect is probably a syntax error at the split point.
-
-Also, see @ref{Location Default Action, ,Default Action for Locations}, which
-describes a special usage of @code{YYLLOC_DEFAULT} in @acronym{GLR} parsers.

-@node Compiler Requirements
-@subsection Considerations when Compiling @acronym{GLR} Parsers
-@cindex @code{inline}
-@cindex @acronym{GLR} parsers and @code{inline}
-
-The @acronym{GLR} parsers require a compiler for @acronym{ISO} C89 or
-later. In addition, they use the @code{inline} keyword, which is not
-C89, but is C99 and is a common extension in pre-C99 compilers. It is
-up to the user of these parsers to handle
-portability issues. For instance, if using Autoconf and the Autoconf
-macro @code{AC_C_INLINE}, a mere
-
-@example
-%@{
- #include <config.h>
-%@}
-@end example
-
-@noindent
-will suffice. Otherwise, we suggest
-
-@example
-%@{
- #if __STDC_VERSION__ < 199901 && ! defined __GNUC__ && ! defined inline
- #define inline

-%@}

-@node Locations Overview
-@section Locations
-@cindex location
-@cindex textual location
-@cindex location, textual
-
-Many applications, like interpreters or compilers, have to produce verbose
-and useful error messages. To achieve this, one must be able to keep track of
-the @dfn{textual location}, or @dfn{location}, of each syntactic construct.
-Bison provides a mechanism for handling these locations.
-
-Each token has a semantic value. In a similar fashion, each token has an
-associated location, but the type of locations is the same for all tokens and
-groupings. Moreover, the output parser is equipped with a default data
-structure for storing locations (@pxref{Locations}, for more details).
-
-Like semantic values, locations can be reached in actions using a dedicated
-set of constructs. In the example above, the location of the whole grouping
-is @code{@@$}, while the locations of the subexpressions are @code{@@1} and
-@code{@@3}.
-
-When a rule is matched, a default action is used to compute the semantic value
-of its left hand side (@pxref{Actions}). In the same way, another default
-action is used for locations. However, the action for locations is general
-enough for most cases, meaning there is usually no need to describe for each
-rule how @code{@@$} should be formed. When building a new location for a given
-grouping, the default behavior of the output parser is to take the beginning
-of the first symbol, and the end of the last symbol.
-
-@node Bison Parser
-@section Bison Output: the Parser File
-@cindex Bison parser
-@cindex Bison utility
-@cindex lexical analyzer, purpose
-@cindex parser
-
-When you run Bison, you give it a Bison grammar file as input. The output
-is a C source file that parses the language described by the grammar.
-This file is called a @dfn{Bison parser}. Keep in mind that the Bison
-utility and the Bison parser are two distinct programs: the Bison utility
-is a program whose output is the Bison parser that becomes part of your
-program.
-
-The job of the Bison parser is to group tokens into groupings according to
-the grammar rules---for example, to build identifiers and operators into
-expressions. As it does this, it runs the actions for the grammar rules it
-uses.
-
-The tokens come from a function called the @dfn{lexical analyzer} that
-you must supply in some fashion (such as by writing it in C). The Bison
-parser calls the lexical analyzer each time it wants a new token. It
-doesn't know what is ``inside'' the tokens (though their semantic values
-may reflect this). Typically the lexical analyzer makes the tokens by
-parsing characters of text, but Bison does not depend on this.
-@xref{Lexical, ,The Lexical Analyzer Function @code{yylex}}.
-
-The Bison parser file is C code which defines a function named
-@code{yyparse} which implements that grammar. This function does not make
-a complete C program: you must supply some additional functions. One is
-the lexical analyzer. Another is an error-reporting function which the
-parser calls to report an error. In addition, a complete C program must
-start with a function called @code{main}; you have to provide this, and
-arrange for it to call @code{yyparse} or the parser will never run.
-@xref{Interface, ,Parser C-Language Interface}.
-
-Aside from the token type names and the symbols in the actions you
-write, all symbols defined in the Bison parser file itself
-begin with @samp{yy} or @samp{YY}. This includes interface functions
-such as the lexical analyzer function @code{yylex}, the error reporting
-function @code{yyerror} and the parser function @code{yyparse} itself.
-This also includes numerous identifiers used for internal purposes.
-Therefore, you should avoid using C identifiers starting with @samp{yy}
-or @samp{YY} in the Bison grammar file except for the ones defined in
-this manual. Also, you should avoid using the C identifiers
-@samp{malloc} and @samp{free} for anything other than their usual
-meanings.
-
-In some cases the Bison parser file includes system headers, and in
-those cases your code should respect the identifiers reserved by those
-headers. On some non-@acronym{GNU} hosts, @code{<alloca.h>}, @code{<malloc.h>},
-@code{<stddef.h>}, and @code{<stdlib.h>} are included as needed to
-declare memory allocators and related types. @code{<libintl.h>} is
-included if message translation is in use
-(@pxref{Internationalization}). Other system headers may
-be included if you define @code{YYDEBUG} to a nonzero value
-(@pxref{Tracing, ,Tracing Your Parser}).

-@node Stages

-
-The actual language-design process using Bison, from grammar specification
-to a working compiler or interpreter, has these parts:
-
-@enumerate
-@item
-Formally specify the grammar in a form recognized by Bison
-(@pxref{Grammar File, ,Bison Grammar Files}). For each grammatical rule
-in the language, describe the action that is to be taken when an
-instance of that rule is recognized. The action is described by a
-sequence of C statements.
-
-@item
-Write a lexical analyzer to process input and pass tokens to the parser.
-The lexical analyzer may be written by hand in C (@pxref{Lexical, ,The
-Lexical Analyzer Function @code{yylex}}). It could also be produced
-using Lex, but the use of Lex is not discussed in this manual.
-
-@item
-Write a controlling function that calls the Bison-produced parser.
-
-@item
-Write error-reporting routines.
-@end enumerate
-
-To turn this source code as written into a runnable program, you
-must follow these steps:
-
-@enumerate

-Run Bison on the grammar to produce the parser.

-@node Grammar Layout
-@section The Overall Layout of a Bison Grammar
-@cindex grammar file
-@cindex file format
-@cindex format of grammar file
-@cindex layout of Bison grammar
-
-The input file for the Bison utility is a @dfn{Bison grammar file}. The
-general form of a Bison grammar file is as follows:
-
-@example
-%@{
-@var{Prologue}
-%@}
-
-@var{Bison declarations}
-
-%%
-@var{Grammar rules}
-%%
-@var{Epilogue}
-@end example
-
-@noindent
-The @samp{%%}, @samp{%@{} and @samp{%@}} are punctuation that appears
-in every Bison grammar file to separate the sections.
-
-The prologue may define types and variables used in the actions. You can
-also use preprocessor commands to define macros used there, and use
-@code{#include} to include header files that do any of these things.
-You need to declare the lexical analyzer @code{yylex} and the error
-printer @code{yyerror} here, along with any other global identifiers
-used by the actions in the grammar rules.
-
-The Bison declarations declare the names of the terminal and nonterminal
-symbols, and may also describe operator precedence and the data types of
-semantic values of various symbols.
-
-The grammar rules define how to construct each nonterminal symbol from its
-parts.
-
-The epilogue can contain any code you want to use. Often the
-definitions of functions declared in the prologue go here. In a
-simple program, all the rest of the program can go here.

-@subsection Declarations for @code{rpcalc}
-
-Here are the C and Bison declarations for the reverse polish notation
-calculator. As in C, comments are placed between @samp{/*@dots{}*/}.
-
-@example
-/* Reverse polish notation calculator. */
-
-%@{
- #define YYSTYPE double
- #include <math.h>
- int yylex (void);
- void yyerror (char const *);
-%@}
-
-%token NUM
-
-%% /* Grammar rules and actions follow. */
-@end example
-
-The declarations section (@pxref{Prologue, , The prologue}) contains two
-preprocessor directives and two forward declarations.
-
-The @code{#define} directive defines the macro @code{YYSTYPE}, thus
-specifying the C data type for semantic values of both tokens and
-groupings (@pxref{Value Type, ,Data Types of Semantic Values}). The
-Bison parser will use whatever type @code{YYSTYPE} is defined as; if you
-don't define it, @code{int} is the default. Because we specify
-@code{double}, each token and each expression has an associated value,
-which is a floating point number.
-
-The @code{#include} directive is used to declare the exponentiation
-function @code{pow}.
-
-The forward declarations for @code{yylex} and @code{yyerror} are
-needed because the C language requires that functions be declared
-before they are used. These functions will be defined in the
-epilogue, but the parser calls them so they must be declared in the
-prologue.
-
-The second section, Bison declarations, provides information to Bison
-about the token types (@pxref{Bison Declarations, ,The Bison
-Declarations Section}). Each terminal symbol that is not a
-single-character literal must be declared here. (Single-character
-literals normally don't need to be declared.) In this example, all the
-arithmetic operators are designated by single-character literals, so the
-only terminal symbol that needs to be declared is @code{NUM}, the token
-type for numeric constants.
-
-@node Rpcalc Rules
-@subsection Grammar Rules for @code{rpcalc}
-
-Here are the grammar rules for the reverse polish notation calculator.
-
-@example
-input: /* empty */
- | input line
-;
-
-line: '\n'
- | exp '\n' @{ printf ("\t%.10g\n", $1); @}
-;
-
-exp: NUM @{ $$ = $1; @}
- | exp exp '+' @{ $$ = $1 + $2; @}
- | exp exp '-' @{ $$ = $1 - $2; @}
- | exp exp '*' @{ $$ = $1 * $2; @}
- | exp exp '/' @{ $$ = $1 / $2; @}
- /* Exponentiation */
- | exp exp '^' @{ $$ = pow ($1, $2); @}
- /* Unary minus */
- | exp 'n' @{ $$ = -$1; @}
-;
-%%
-@end example
-
-The groupings of the rpcalc ``language'' defined here are the expression
-(given the name @code{exp}), the line of input (@code{line}), and the
-complete input transcript (@code{input}). Each of these nonterminal
-symbols has several alternate rules, joined by the vertical bar @samp{|}
-which is read as ``or''. The following sections explain what these rules
-mean.
-
-The semantics of the language is determined by the actions taken when a
-grouping is recognized. The actions are the C code that appears inside
-braces. @xref{Actions}.
-
-You must specify these actions in C, but Bison provides the means for
-passing semantic values between the rules. In each action, the
-pseudo-variable @code{$$} stands for the semantic value for the grouping
-that the rule is going to construct. Assigning a value to @code{$$} is the
-main job of most actions. The semantic values of the components of the
-rule are referred to as @code{$1}, @code{$2}, and so on.

-@node Rpcalc Input
-@subsubsection Explanation of @code{input}
-
-Consider the definition of @code{input}:
-
-@example
-input: /* empty */
- | input line
-;
-@end example
-
-This definition reads as follows: ``A complete input is either an empty
-string, or a complete input followed by an input line''. Notice that
-``complete input'' is defined in terms of itself. This definition is said
-to be @dfn{left recursive} since @code{input} appears always as the
-leftmost symbol in the sequence. @xref{Recursion, ,Recursive Rules}.
-
-The first alternative is empty because there are no symbols between the
-colon and the first @samp{|}; this means that @code{input} can match an
-empty string of input (no tokens). We write the rules this way because it
-is legitimate to type @kbd{Ctrl-d} right after you start the calculator.
-It's conventional to put an empty alternative first and write the comment
-@samp{/* empty */} in it.
-
-The second alternate rule (@code{input line}) handles all nontrivial input.
-It means, ``After reading any number of lines, read one more line if
-possible.'' The left recursion makes this rule into a loop. Since the
-first alternative matches empty input, the loop can be executed zero or
-more times.
-
-The parser function @code{yyparse} continues to process input until a
-grammatical error is seen or the lexical analyzer says there are no more
-input tokens; we will arrange for the latter to happen at end-of-input.
-
-@node Rpcalc Line
-@subsubsection Explanation of @code{line}
-
-Now consider the definition of @code{line}:
-
-@example
-line: '\n'
- | exp '\n' @{ printf ("\t%.10g\n", $1); @}
-;
-@end example
-
-The first alternative is a token which is a newline character; this means
-that rpcalc accepts a blank line (and ignores it, since there is no
-action). The second alternative is an expression followed by a newline.
-This is the alternative that makes rpcalc useful. The semantic value of
-the @code{exp} grouping is the value of @code{$1} because the @code{exp} in
-question is the first symbol in the alternative. The action prints this
-value, which is the result of the computation the user asked for.
-
-This action is unusual because it does not assign a value to @code{$$}. As
-a consequence, the semantic value associated with the @code{line} is
-uninitialized (its value will be unpredictable). This would be a bug if
-that value were ever used, but we don't use it: once rpcalc has printed the
-value of the user's input line, that value is no longer needed.
-
-@node Rpcalc Expr
-@subsubsection Explanation of @code{expr}
-
-The @code{exp} grouping has several rules, one for each kind of expression.
-The first rule handles the simplest expressions: those that are just numbers.
-The second handles an addition-expression, which looks like two expressions
-followed by a plus-sign. The third handles subtraction, and so on.
-
-@example
-exp: NUM
- | exp exp '+' @{ $$ = $1 + $2; @}
- | exp exp '-' @{ $$ = $1 - $2; @}
- @dots{}
- ;
-@end example
-
-We have used @samp{|} to join all the rules for @code{exp}, but we could
-equally well have written them separately:
-
-@example
-exp: NUM ;
-exp: exp exp '+' @{ $$ = $1 + $2; @} ;
-exp: exp exp '-' @{ $$ = $1 - $2; @} ;
- @dots{}
-@end example
-
-Most of the rules have actions that compute the value of the expression in
-terms of the value of its parts. For example, in the rule for addition,
-@code{$1} refers to the first component @code{exp} and @code{$2} refers to
-the second one. The third component, @code{'+'}, has no meaningful
-associated semantic value, but if it had one you could refer to it as
-@code{$3}. When @code{yyparse} recognizes a sum expression using this
-rule, the sum of the two subexpressions' values is produced as the value of
-the entire expression. @xref{Actions}.
-
-You don't have to give an action for every rule. When a rule has no
-action, Bison by default copies the value of @code{$1} into @code{$$}.
-This is what happens in the first rule (the one that uses @code{NUM}).
-
-The formatting shown here is the recommended convention, but Bison does
-not require it. You can add or change white space as much as you wish.
-For example, this:
-
-@example
-exp : NUM | exp exp '+' @{$$ = $1 + $2; @} | @dots{} ;
-@end example
-
-@noindent
-means the same thing as this:
-
-@example
-exp: NUM
- | exp exp '+' @{ $$ = $1 + $2; @}
- | @dots{}
-;
-@end example
-
-@noindent
-The latter, however, is much more readable.

-@node Rpcalc Lexer
-@subsection The @code{rpcalc} Lexical Analyzer
-@cindex writing a lexical analyzer
-@cindex lexical analyzer, writing
-
-The lexical analyzer's job is low-level parsing: converting characters
-or sequences of characters into tokens. The Bison parser gets its
-tokens by calling the lexical analyzer. @xref{Lexical, ,The Lexical
-Analyzer Function @code{yylex}}.
-
-Only a simple lexical analyzer is needed for the @acronym{RPN}
-calculator. This
-lexical analyzer skips blanks and tabs, then reads in numbers as
-@code{double} and returns them as @code{NUM} tokens. Any other character
-that isn't part of a number is a separate token. Note that the token-code
-for such a single-character token is the character itself.
-
-The return value of the lexical analyzer function is a numeric code which
-represents a token type. The same text used in Bison rules to stand for
-this token type is also a C expression for the numeric code for the type.
-This works in two ways. If the token type is a character literal, then its
-numeric code is that of the character; you can use the same
-character literal in the lexical analyzer to express the number. If the
-token type is an identifier, that identifier is defined by Bison as a C
-macro whose definition is the appropriate number. In this example,
-therefore, @code{NUM} becomes a macro for @code{yylex} to use.
-
-The semantic value of the token (if it has one) is stored into the
-global variable @code{yylval}, which is where the Bison parser will look
-for it. (The C data type of @code{yylval} is @code{YYSTYPE}, which was
-defined at the beginning of the grammar; @pxref{Rpcalc Decls,
-,Declarations for @code{rpcalc}}.)
-
-A token type code of zero is returned if the end-of-input is encountered.
-(Bison recognizes any nonpositive value as indicating end-of-input.)
-
-Here is the code for the lexical analyzer:
-
-@example
-@group
-/* The lexical analyzer returns a double floating point
- number on the stack and the token NUM, or the numeric code
- of the character read if not a number. It skips all blanks
- and tabs, and returns 0 for end-of-input. */
-
-#include <ctype.h>
-@end group
-

-@node Rpcalc Main
-@subsection The Controlling Function
-@cindex controlling function
-@cindex main function in simple example
-
-In keeping with the spirit of this example, the controlling function is
-kept to the bare minimum. The only requirement is that it call
-@code{yyparse} to start the process of parsing.
-
-@example
-@group
-int
-main (void)
-@{
- return yyparse ();
-@}
-@end group
-@end example
-
-@node Rpcalc Error
-@subsection The Error Reporting Routine
-@cindex error reporting routine
-
-When @code{yyparse} detects a syntax error, it calls the error reporting
-function @code{yyerror} to print an error message (usually but not
-always @code{"syntax error"}). It is up to the programmer to supply
-@code{yyerror} (@pxref{Interface, ,Parser C-Language Interface}), so
-here is the definition we will use:
-
-@example
-@group
-#include <stdio.h>
-
-/* Called by yyparse on error. */
-void
-yyerror (char const *s)
-@{
- fprintf (stderr, "%s\n", s);
-@}
-@end group
-@end example
-
-After @code{yyerror} returns, the Bison parser may recover from the error
-and continue parsing if the grammar contains a suitable error rule
-(@pxref{Error Recovery}). Otherwise, @code{yyparse} returns nonzero. We
-have not written any error rules in this example, so any invalid input will
-cause the calculator program to exit. This is not clean behavior for a
-real calculator, but it is adequate for the first example.
-
-@node Rpcalc Gen
-@subsection Running Bison to Make the Parser
-@cindex running Bison (introduction)
-
-Before running Bison to produce a parser, we need to decide how to
-arrange all the source code in one or more source files. For such a
-simple example, the easiest thing is to put everything in one file. The
-definitions of @code{yylex}, @code{yyerror} and @code{main} go at the
-end, in the epilogue of the file
-(@pxref{Grammar Layout, ,The Overall Layout of a Bison Grammar}).
-
-For a large project, you would probably have several source files, and use
-@code{make} to arrange to recompile them.
-
-With all the source in a single file, you use the following command to
-convert it into a parser file:
-
-@example
-bison @var{file}.y
-@end example
-
-@noindent
-In this example the file was called @file{rpcalc.y} (for ``Reverse Polish
-@sc{calc}ulator''). Bison produces a file named @file{@var{file}.tab.c},
-removing the @samp{.y} from the original file name. The file output by
-Bison contains the source code for @code{yyparse}. The additional
-functions in the input file (@code{yylex}, @code{yyerror} and @code{main})
-are copied verbatim to the output.
-
-@node Rpcalc Compile
-@subsection Compiling the Parser File
-@cindex compiling the parser
-
-Here is how to compile and run the parser file:

-@group
-# @r{List files in current directory.}
-$ @kbd{ls}
-rpcalc.tab.c rpcalc.y
-@end group

-@group
-# @r{Compile the Bison parser.}

-We now modify rpcalc to handle infix operators instead of postfix. Infix
-notation involves the concept of operator precedence and the need for

-@file{calc.y}, an infix desk-top calculator.
-

- | '(' exp ')' @{ $$ = $2; @}
-;
-%%
-@end example
-
-@noindent
-The functions @code{yylex}, @code{yyerror} and @code{main} can be the
-same as before.
-
-There are two important new features shown in this code.
-
-In the second section (Bison declarations), @code{%left} declares token
-types and says they are left-associative operators. The declarations
-@code{%left} and @code{%right} (right associativity) take the place of
-@code{%token} which is used to declare a token type name without
-associativity. (These tokens are single-character literals, which
-ordinarily don't need to be declared. We declare them here to specify
-the associativity.)
-
-Operator precedence is determined by the line ordering of the
-declarations; the higher the line number of the declaration (lower on
-the page or screen), the higher the precedence. Hence, exponentiation
-has the highest precedence, unary minus (@code{NEG}) is next, followed
-by @samp{*} and @samp{/}, and so on. @xref{Precedence, ,Operator
-Precedence}.
-
-The other important new feature is the @code{%prec} in the grammar
-section for the unary minus operator. The @code{%prec} simply instructs
-Bison that the rule @samp{| '-' exp} has the same precedence as
-@code{NEG}---in this case the next-to-highest. @xref{Contextual
-Precedence, ,Context-Dependent Precedence}.
-
-Here is a sample run of @file{calc.y}:
-
-@need 500
-@example

-@kbd{4 + 4.5 - (34/(8*3+-3))}

-
-@node Simple Error Recovery
-@section Simple Error Recovery
-@cindex error recovery, simple
-
-Up to this point, this manual has not addressed the issue of @dfn{error
-recovery}---how to continue parsing after the parser detects a syntax
-error. All we have handled is error reporting with @code{yyerror}.
-Recall that by default @code{yyparse} returns after calling
-@code{yyerror}. This means that an erroneous input line causes the
-calculator program to exit. Now we show how to rectify this deficiency.
-
-The Bison language itself includes the reserved word @code{error}, which
-may be included in the grammar rules. In the example below it has
-been added to one of the alternatives for @code{line}:
-
-@example
-@group
-line: '\n'
- | exp '\n' @{ printf ("\t%.10g\n", $1); @}
- | error '\n' @{ yyerrok; @}
-;
-@end group
-@end example
-
-This addition to the grammar allows for simple error recovery in the
-event of a syntax error. If an expression that cannot be evaluated is
-read, the error will be recognized by the third rule for @code{line},
-and parsing will continue. (The @code{yyerror} function is still called
-upon to print its message as well.) The action executes the statement
-@code{yyerrok}, a macro defined automatically by Bison; its meaning is
-that error recovery is complete (@pxref{Error Recovery}). Note the
-difference between @code{yyerrok} and @code{yyerror}; neither one is a
-misprint.
-
-This form of error recovery deals with syntax errors. There are other
-kinds of errors; for example, division by zero, which raises an exception
-signal that is normally fatal. A real calculator program must handle this
-signal and use @code{longjmp} to return to @code{main} and resume parsing
-input lines; it would also have to discard the rest of the current line of
-input. We won't discuss this issue further because it is not specific to
-Bison programs.

-
-This code shows how to reach locations inside of semantic actions, by
-using the pseudo-variables @code{@@@var{n}} for rule components, and the
-pseudo-variable @code{@@$} for groupings.
-
-We don't need to assign a value to @code{@@$}: the output parser does it
-automatically. By default, before executing the C code of each action,
-@code{@@$} is set to range from the beginning of @code{@@1} to the end
-of @code{@@@var{n}}, for a rule with @var{n} components. This behavior
-can be redefined (@pxref{Location Default Action, , Default Action for

-
-@node Ltcalc Lexer
-@subsection The @code{ltcalc} Lexical Analyzer.
-
-Until now, we relied on Bison's defaults to enable location
-tracking. The next step is to rewrite the lexical analyzer, and make it
-able to feed the parser with the token locations, as it already does for
-semantic values.
-
-To this end, we must take into account every single character of the
-input text, to avoid the computed locations of being fuzzy or wrong:
-
-@example
-@group
-int
-yylex (void)
-@{
- int c;
-@end group
-
-@group
- /* Skip white space. */
- while ((c = getchar ()) == ' ' || c == '\t')
- ++yylloc.last_column;
-@end group
-
-@group
- /* Step. */
- yylloc.first_line = yylloc.last_line;
- yylloc.first_column = yylloc.last_column;
-@end group
-
-@group
- /* Process numbers. */
- if (isdigit (c))
- @{
- yylval = c - '0';
- ++yylloc.last_column;
- while (isdigit (c = getchar ()))
- @{
- ++yylloc.last_column;
- yylval = yylval * 10 + c - '0';
- @}
- ungetc (c, stdin);
- return NUM;
- @}
-@end group
-
- /* Return end-of-input. */
- if (c == EOF)
- return 0;
-
- /* Return a single char, and update location. */
- if (c == '\n')
- @{
- ++yylloc.last_line;
- yylloc.last_column = 0;
- @}
- else
- ++yylloc.last_column;
- return c;
-@}
-@end example
-
-Basically, the lexical analyzer performs the same processing as before:
-it skips blanks and tabs, and reads numbers or single-character tokens.
-In addition, it updates @code{yylloc}, the global variable (of type
-@code{YYLTYPE}) containing the token's location.
-
-Now, each time this function returns a token, the parser has its number
-as well as its semantic value, and its location in the text. The last
-needed change is to initialize @code{yylloc}, for example in the
-controlling function:
-
-@example
-@group
-int
-main (void)
-@{
- yylloc.first_line = yylloc.last_line = 1;
- yylloc.first_column = yylloc.last_column = 0;
- return yyparse ();
-@}
-@end group
-@end example
-
-Remember that computing locations is not a matter of syntax. Every
-character must be associated to a location update, whether it is in
-valid input, in comments, in literal strings, and so on.

-
-Now that the basics of Bison have been discussed, it is time to move on to
-a more advanced problem. The above calculators provided only five

-be nice to have a calculator that provides other mathematical functions such
-as @code{sin}, @code{cos}, etc.
-
-It is easy to add new operators to the infix calculator as long as they are
-only single-character literals. The lexical analyzer @code{yylex} passes
-back all nonnumeric characters as tokens, so new grammar rules suffice for
-adding a new operator. But we want something more flexible: built-in
-functions whose syntax has this form:
-
-@example
-@var{function_name} (@var{argument})

-(@pxref{Multiple Types, ,More Than One Value Type}).
-
-The @code{%union} declaration specifies the entire list of possible types;
-this is instead of defining @code{YYSTYPE}. The allowable types are now
-double-floats (for @code{exp} and @code{NUM}) and pointers to entries in
-the symbol table. @xref{Union Decl, ,The Collection of Value Types}.
-
-Since values can now have various types, it is necessary to associate a
-type with each grammar symbol whose semantic value is used. These symbols
-are @code{NUM}, @code{VAR}, @code{FNCT}, and @code{exp}. Their
-declarations are augmented with information about their data type (placed
-between angle brackets).
-
-The Bison construct @code{%type} is used for declaring nonterminal
-symbols, just as @code{%token} is used for declaring token types. We
-have not used @code{%type} before because nonterminal symbols are
-normally declared implicitly by the rules that define them. But
-@code{exp} must be declared explicitly so we can specify its value type.

-names and meanings of variables and functions. This doesn't affect the
-grammar rules (except for the actions) or the Bison declarations, but it
-requires some additional C functions for support.
-
-The symbol table itself consists of a linked list of records. Its
-definition, which is kept in the header @file{calc.h}, is as follows. It
-provides for either functions or variables to be placed in the table.

-The new version of @code{main} includes a call to @code{init_table}, a
-function that initializes the symbol table. Here it is, and

-By simply editing the initialization list and adding the necessary include
-files, you can add additional functions to the calculator.

-Two important functions allow look-up and installation of symbols in the
-symbol table. The function @code{putsym} is passed a name and the type
-(@code{VAR} or @code{FNCT}) of the object to be installed. The object is
-linked to the front of the list, and a pointer to the object is returned.
-The function @code{getsym} is passed the name of the symbol to look up. If
-found, a pointer to that symbol is returned; otherwise zero is returned.

-@end smallexample
-
-The function @code{yylex} must now recognize variables, numeric values, and
-the single-character arithmetic operators. Strings of alphanumeric
-characters with a leading letter are recognized as either variables or
-functions depending on what the symbol table says about them.
-
-The string is passed to @code{getsym} for look up in the symbol table. If
-the name appears in the table, a pointer to its location and its type
-(@code{VAR} or @code{FNCT}) is returned to @code{yyparse}. If it is not
-already in the table, then it is installed as a @code{VAR} using
-@code{putsym}. Again, a pointer and its type (which must be @code{VAR}) is
-returned to @code{yyparse}.
-
-No change is needed in the handling of numeric values and arithmetic
-operators in @code{yylex}.

-@cindex declarations section
-@cindex Prologue
-@cindex declarations
-
-The @var{Prologue} section contains macro definitions and declarations
-of functions and variables that are used in the actions in the grammar
-rules. These are copied to the beginning of the parser file so that
-they precede the definition of @code{yyparse}. You can use
-@samp{#include} to get the declarations from a header file. If you
-don't need any C declarations, you may omit the @samp{%@{} and
-@samp{%@}} delimiters that bracket this section.
-
-The @var{Prologue} section is terminated by the the first occurrence
-of @samp{%@}} that is outside a comment, a string literal, or a
-character constant.
-
-You may have more than one @var{Prologue} section, intermixed with the
-@var{Bison declarations}. This allows you to have C and Bison
-declarations that refer to each other. For example, the @code{%union}
-declaration may use types defined in a header file, and you may wish to
-prototype functions that take arguments of type @code{YYSTYPE}. This
-can be done with two @var{Prologue} blocks, one before and one after the

-The @var{Epilogue} is copied verbatim to the end of the parser file, just as
-the @var{Prologue} is copied to the beginning. This is the most convenient
-place to put anything that you want to have in the parser file but which need
-not come before the definition of @code{yyparse}. For example, the
-definitions of @code{yylex} and @code{yyerror} often go here. Because
-C requires functions to be declared before being used, you often need
-to declare functions like @code{yylex} and @code{yyerror} in the Prologue,
-even if you define them in the Epilogue.
-@xref{Interface, ,Parser C-Language Interface}.
-
-If the last section is empty, you may omit the @samp{%%} that separates it
-from the grammar rules.
-
-The Bison parser itself contains many macros and identifiers whose names
-start with @samp{yy} or @samp{YY}, so it is a good idea to avoid using
-any such names (except those documented in this manual) in the epilogue
-of the grammar file.
-
-@node Symbols
-@section Symbols, Terminal and Nonterminal
-@cindex nonterminal symbol
-@cindex terminal symbol
-@cindex token type
-@cindex symbol
-
-@dfn{Symbols} in Bison grammars represent the grammatical classifications
-of the language.
-
-A @dfn{terminal symbol} (also known as a @dfn{token type}) represents a
-class of syntactically equivalent tokens. You use the symbol in grammar
-rules to mean that a token in that class is allowed. The symbol is
-represented in the Bison parser by a numeric code, and the @code{yylex}
-function returns a token type code to indicate what kind of token has
-been read. You don't need to know what the code value is; you can use
-the symbol to stand for it.
-
-A @dfn{nonterminal symbol} stands for a class of syntactically
-equivalent groupings. The symbol name is used in writing grammar rules.
-By convention, it should be all lower case.
-
-Symbol names can contain letters, digits (not at the beginning),
-underscores and periods. Periods make sense only in nonterminals.
-
-There are three ways of writing terminal symbols in the grammar:
-
-@itemize @bullet
-@item
-A @dfn{named token type} is written with an identifier, like an
-identifier in C@. By convention, it should be all upper case. Each
-such name must be defined with a Bison declaration such as
-@code{%token}. @xref{Token Decl, ,Token Type Names}.
-
-@item
-@cindex character token
-@cindex literal token
-@cindex single-character literal
-A @dfn{character token type} (or @dfn{literal character token}) is
-written in the grammar using the same syntax used in C for character
-constants; for example, @code{'+'} is a character token type. A
-character token type doesn't need to be declared unless you need to
-specify its semantic value data type (@pxref{Value Type, ,Data Types of
-Semantic Values}), associativity, or precedence (@pxref{Precedence,
-,Operator Precedence}).
-
-By convention, a character token type is used only to represent a
-token that consists of that particular character. Thus, the token
-type @code{'+'} is used to represent the character @samp{+} as a
-token. Nothing enforces this convention, but if you depart from it,
-your program will confuse other readers.
-
-All the usual escape sequences used in character literals in C can be
-used in Bison as well, but you must not use the null character as a
-character literal because its numeric code, zero, signifies
-end-of-input (@pxref{Calling Convention, ,Calling Convention
-for @code{yylex}}). Also, unlike standard C, trigraphs have no
-special meaning in Bison character literals, nor is backslash-newline
-allowed.
-
-@item
-@cindex string token
-@cindex literal string token
-@cindex multicharacter literal
-A @dfn{literal string token} is written like a C string constant; for
-example, @code{"<="} is a literal string token. A literal string token
-doesn't need to be declared unless you need to specify its semantic
-value data type (@pxref{Value Type}), associativity, or precedence
-(@pxref{Precedence}).
-
-You can associate the literal string token with a symbolic name as an
-alias, using the @code{%token} declaration (@pxref{Token Decl, ,Token
-Declarations}). If you don't do that, the lexical analyzer has to
-retrieve the token number for the literal string token from the
-@code{yytname} table (@pxref{Calling Convention}).
-
-@strong{Warning}: literal string tokens do not work in Yacc.
-
-By convention, a literal string token is used only to represent a token
-that consists of that particular string. Thus, you should use the token
-type @code{"<="} to represent the string @samp{<=} as a token. Bison
-does not enforce this convention, but if you depart from it, people who
-read your program will be confused.
-
-All the escape sequences used in string literals in C can be used in
-Bison as well, except that you must not use a null character within a
-string literal. Also, unlike Standard C, trigraphs have no special
-meaning in Bison string literals, nor is backslash-newline allowed. A
-literal string token must contain two or more characters; for a token
-containing just one character, use a character token (see above).
-@end itemize
-
-How you choose to write a terminal symbol has no effect on its
-grammatical meaning. That depends only on where it appears in rules and
-on when the parser function returns that symbol.
-
-The value returned by @code{yylex} is always one of the terminal
-symbols, except that a zero or negative value signifies end-of-input.
-Whichever way you write the token type in the grammar rules, you write
-it the same way in the definition of @code{yylex}. The numeric code
-for a character token type is simply the positive numeric code of the
-character, so @code{yylex} can use the identical value to generate the
-requisite code, though you may need to convert it to @code{unsigned
-char} to avoid sign-extension on hosts where @code{char} is signed.
-Each named token type becomes a C macro in
-the parser file, so @code{yylex} can use the name to stand for the code.
-(This is why periods don't make sense in terminal symbols.)
-@xref{Calling Convention, ,Calling Convention for @code{yylex}}.
-
-If @code{yylex} is defined in a separate file, you need to arrange for the
-token-type macro definitions to be available there. Use the @samp{-d}
-option when you run Bison, so that it will write these macro definitions
-into a separate header file @file{@var{name}.tab.h} which you can include
-in the other source files that need it. @xref{Invocation, ,Invoking Bison}.
-
-If you want to write a grammar that is portable to any Standard C
-host, you must use only nonnull character tokens taken from the basic
-execution character set of Standard C@. This set consists of the ten
-digits, the 52 lower- and upper-case English letters, and the
-characters in the following C-language string:
-
-@example
-"\a\b\t\n\v\f\r !\"#%&'()*+,-./:;<=>?[\\]^_@{|@}~"
-@end example
-
-The @code{yylex} function and Bison must use a consistent character set
-and encoding for character tokens. For example, if you run Bison in an
-@acronym{ASCII} environment, but then compile and run the resulting
-program in an environment that uses an incompatible character set like
-@acronym{EBCDIC}, the resulting program may not work because the tables
-generated by Bison will assume @acronym{ASCII} numeric values for
-character tokens. It is standard practice for software distributions to
-contain C source files that were generated by Bison in an
-@acronym{ASCII} environment, so installers on platforms that are
-incompatible with @acronym{ASCII} must rebuild those files before
-compiling them.
-
-The symbol @code{error} is a terminal symbol reserved for error recovery
-(@pxref{Error Recovery}); you shouldn't use it for any other purpose.
-In particular, @code{yylex} should never return this value. The default
-value of the error token is 256, unless you explicitly assigned 256 to
-one of your tokens with a @code{%token} declaration.
-
-@node Rules
-@section Syntax of Grammar Rules
-@cindex rule syntax
-@cindex grammar rule syntax
-@cindex syntax of grammar rules
-
-A Bison grammar rule has the following general form:
-
-@example
-@group
-@var{result}: @var{components}@dots{}
- ;
-@end group
-@end example
-
-@noindent
-where @var{result} is the nonterminal symbol that this rule describes,
-and @var{components} are various terminal and nonterminal symbols that
-are put together by this rule (@pxref{Symbols}).
-
-For example,
-
-@example
-@group
-exp: exp '+' exp
- ;
-@end group
-@end example
-
-@noindent
-says that two groupings of type @code{exp}, with a @samp{+} token in between,
-can be combined into a larger grouping of type @code{exp}.
-
-White space in rules is significant only to separate symbols. You can add
-extra white space as you wish.
-
-Scattered among the components can be @var{actions} that determine
-the semantics of the rule. An action looks like this:
-
-@example
-@{@var{C statements}@}
-@end example
-
-@noindent
-@cindex braced code
-This is an example of @dfn{braced code}, that is, C code surrounded by
-braces, much like a compound statement in C@. Braced code can contain
-any sequence of C tokens, so long as its braces are balanced. Bison
-does not check the braced code for correctness directly; it merely
-copies the code to the output file, where the C compiler can check it.
-
-Within braced code, the balanced-brace count is not affected by braces
-within comments, string literals, or character constants, but it is
-affected by the C digraphs @samp{<%} and @samp{%>} that represent
-braces. At the top level braced code must be terminated by @samp{@}}
-and not by a digraph. Bison does not look for trigraphs, so if braced
-code uses trigraphs you should ensure that they do not affect the
-nesting of braces or the boundaries of comments, string literals, or
-character constants.
-
-Usually there is only one action and it follows the components.
-@xref{Actions}.
-
-@findex |
-Multiple rules for the same @var{result} can be written separately or can
-be joined with the vertical-bar character @samp{|} as follows:
-
-@example
-@group
-@var{result}: @var{rule1-components}@dots{}
- | @var{rule2-components}@dots{}
- @dots{}
- ;
-@end group
-@end example
-
-@noindent
-They are still considered distinct rules even when joined in this way.
-
-If @var{components} in a rule is empty, it means that @var{result} can
-match the empty string. For example, here is how to define a
-comma-separated sequence of zero or more @code{exp} groupings:
-
-@example
-@group
-expseq: /* empty */
- | expseq1
- ;
-@end group
-
-@group
-expseq1: exp
- | expseq1 ',' exp
- ;
-@end group
-@end example
-
-@noindent
-It is customary to write a comment @samp{/* empty */} in each rule
-with no components.
-
-@node Recursion
-@section Recursive Rules
-@cindex recursive rule
-
-A rule is called @dfn{recursive} when its @var{result} nonterminal
-appears also on its right hand side. Nearly all Bison grammars need to
-use recursion, because that is the only way to define a sequence of any
-number of a particular thing. Consider this recursive definition of a
-comma-separated sequence of one or more expressions:
-
-@example
-@group
-expseq1: exp
- | expseq1 ',' exp
- ;
-@end group
-@end example
-
-@cindex left recursion
-@cindex right recursion
-@noindent
-Since the recursive use of @code{expseq1} is the leftmost symbol in the
-right hand side, we call this @dfn{left recursion}. By contrast, here
-the same construct is defined using @dfn{right recursion}:
-
-@example
-@group
-expseq1: exp
- | exp ',' expseq1
- ;
-@end group
-@end example
-
-@noindent
-Any kind of sequence can be defined using either left recursion or right
-recursion, but you should always use left recursion, because it can
-parse a sequence of any number of elements with bounded stack space.
-Right recursion uses up space on the Bison stack in proportion to the
-number of elements in the sequence, because all the elements must be
-shifted onto the stack before the rule can be applied even once.
-@xref{Algorithm, ,The Bison Parser Algorithm}, for further explanation
-of this.
-
-@cindex mutual recursion
-@dfn{Indirect} or @dfn{mutual} recursion occurs when the result of the
-rule does not appear directly on its right hand side, but does appear
-in rules for other nonterminals which do appear on its right hand
-side.
-
-For example:
-
-@example
-@group
-expr: primary
- | primary '+' primary
- ;
-@end group
-
-@group
-primary: constant
- | '(' expr ')'
- ;
-@end group
-@end example
-
-@noindent
-defines two mutually-recursive nonterminals, since each refers to the
-other.

-@node Semantics

-@cindex language semantics, defining
-
-The grammar rules for a language determine only the syntax. The semantics
-are determined by the semantic values associated with various tokens and
-groupings, and by the actions taken when various groupings are recognized.
-
-For example, the calculator calculates properly because the value
-associated with each expression is the proper number; it adds properly
-because the action for the grouping @w{@samp{@var{x} + @var{y}}} is to add
-the numbers associated with @var{x} and @var{y}.

-@cindex value type, semantic
-@cindex data types of semantic values
-@cindex default data type
-
-In a simple program it may be sufficient to use the same data type for
-the semantic values of all language constructs. This was true in the
-@acronym{RPN} and infix calculator examples (@pxref{RPN Calc, ,Reverse Polish
-Notation Calculator}).
-
-Bison's default is to use type @code{int} for all semantic values. To
-specify some other type, define @code{YYSTYPE} as a macro, like this:
-
-@example
-#define YYSTYPE double
-@end example
-
-@noindent
-@code{YYSTYPE}'s replacement list should be a type name
-that does not contain parentheses or square brackets.
-This macro definition must go in the prologue of the grammar file
-(@pxref{Grammar Outline, ,Outline of a Bison Grammar}).
-
-@node Multiple Types
-@subsection More Than One Value Type
-
-In most programs, you will need different data types for different kinds
-of tokens and groupings. For example, a numeric constant may need type
-@code{int} or @code{long int}, while a string constant needs type
-@code{char *}, and an identifier might need a pointer to an entry in the
-symbol table.
-
-To use more than one data type for semantic values in one parser, Bison
-requires you to do two things:
-
-@itemize @bullet

-@subsection Actions
-@cindex action
-@vindex $$
-@vindex $@var{n}
-
-An action accompanies a syntactic rule and contains C code to be executed
-each time an instance of that rule is recognized. The task of most actions
-is to compute a semantic value for the grouping built by the rule from the
-semantic values associated with tokens or smaller groupings.
-
-An action consists of braced code containing C statements, and can be
-placed at any position in the rule;
-it is executed at that position. Most rules have just one action at the
-end of the rule, following all the components. Actions in the middle of
-a rule are tricky and used only for special purposes (@pxref{Mid-Rule
-Actions, ,Actions in Mid-Rule}).
-
-The C code in an action can refer to the semantic values of the components
-matched by the rule with the construct @code{$@var{n}}, which stands for
-the value of the @var{n}th component. The semantic value for the grouping
-being constructed is @code{$$}. Bison translates both of these
-constructs into expressions of the appropriate type when it copies the
-actions into the parser file. @code{$$} is translated to a modifiable
-lvalue, so it can be assigned to.
-
-Here is a typical example:
-
-@example
-@group
-exp: @dots{}
- | exp '+' exp
- @{ $$ = $1 + $3; @}
-@end group
-@end example
-
-@noindent
-This rule constructs an @code{exp} from two smaller @code{exp} groupings
-connected by a plus-sign token. In the action, @code{$1} and @code{$3}
-refer to the semantic values of the two component @code{exp} groupings,
-which are the first and third symbols on the right hand side of the rule.
-The sum is stored into @code{$$} so that it becomes the semantic value of
-the addition-expression just recognized by the rule. If there were a
-useful semantic value associated with the @samp{+} token, it could be
-referred to as @code{$2}.
-
-Note that the vertical-bar character @samp{|} is really a rule
-separator, and actions are attached to a single rule. This is a
-difference with tools like Flex, for which @samp{|} stands for either
-``or'', or ``the same action as that of the next rule''. In the
-following example, the action is triggered only when @samp{b} is found:
-
-@example
-@group
-a-or-b: 'a'|'b' @{ a_or_b_found = 1; @};
-@end group
-@end example
-
-@cindex default action
-If you don't specify an action for a rule, Bison supplies a default:
-@w{@code{$$ = $1}.} Thus, the value of the first symbol in the rule
-becomes the value of the whole rule. Of course, the default action is
-valid only if the two data types match. There is no meaningful default
-action for an empty rule; every empty rule must have an explicit action
-unless the rule's value does not matter.
-
-@code{$@var{n}} with @var{n} zero or negative is allowed for reference
-to tokens and groupings on the stack @emph{before} those that match the
-current rule. This is a very risky practice, and to use it reliably
-you must be certain of the context in which the rule is applied. Here
-is a case in which you can use this reliably:
-
-@example
-@group
-foo: expr bar '+' expr @{ @dots{} @}
- | expr bar '-' expr @{ @dots{} @}
- ;
-@end group
-
-@group
-bar: /* empty */
- @{ previous_expr = $0; @}
- ;
-@end group
-@end example
-
-As long as @code{bar} is used only in the fashion shown here, @code{$0}
-always refers to the @code{expr} which precedes @code{bar} in the
-definition of @code{foo}.
-
-@vindex yylval
-It is also possible to access the semantic value of the look-ahead token, if
-any, from a semantic action.
-This semantic value is stored in @code{yylval}.
-@xref{Action Features, ,Special Features for Use in Actions}.
-
-@node Action Types
-@subsection Data Types of Values in Actions
-@cindex action data types
-@cindex data types in actions
-
-If you have chosen a single data type for semantic values, the @code{$$}
-and @code{$@var{n}} constructs always have that data type.
-
-If you have used @code{%union} to specify a variety of data types, then you
-must declare a choice among these types for each terminal or nonterminal
-symbol that can have a semantic value. Then each time you use @code{$$} or
-@code{$@var{n}}, its data type is determined by which symbol it refers to
-in the rule. In this example,
-
-@example
-@group
-exp: @dots{}
- | exp '+' exp
- @{ $$ = $1 + $3; @}
-@end group
-@end example
-
-@noindent
-@code{$1} and @code{$3} refer to instances of @code{exp}, so they all
-have the data type declared for the nonterminal symbol @code{exp}. If
-@code{$2} were used, it would have the data type declared for the
-terminal symbol @code{'+'}, whatever that might be.
-
-Alternatively, you can specify the data type when you refer to the value,
-by inserting @samp{<@var{type}>} after the @samp{$} at the beginning of the
-reference. For example, if you have defined types as shown here:
-
-@example
-@group
-%union @{
- int itype;
- double dtype;
-@}
-@end group
-@end example
-
-@noindent
-then you can write @code{$<itype>1} to refer to the first subunit of the
-rule as an integer, or @code{$<dtype>1} to refer to it as a double.
-
-@node Mid-Rule Actions
-@subsection Actions in Mid-Rule
-@cindex actions in mid-rule
-@cindex mid-rule actions
-
-Occasionally it is useful to put an action in the middle of a rule.
-These actions are written just like usual end-of-rule actions, but they
-are executed before the parser even recognizes the following components.
-
-A mid-rule action may refer to the components preceding it using
-@code{$@var{n}}, but it may not refer to subsequent components because
-it is run before they are parsed.
-
-The mid-rule action itself counts as one of the components of the rule.
-This makes a difference when there is another action later in the same rule
-(and usually there is another at the end): you have to count the actions
-along with the symbols when working out which number @var{n} to use in
-@code{$@var{n}}.
-
-The mid-rule action can also have a semantic value. The action can set
-its value with an assignment to @code{$$}, and actions later in the rule
-can refer to the value using @code{$@var{n}}. Since there is no symbol
-to name the action, there is no way to declare a data type for the value
-in advance, so you must use the @samp{$<@dots{}>@var{n}} construct to
-specify a data type each time you refer to this value.
-
-There is no way to set the value of the entire rule with a mid-rule
-action, because assignments to @code{$$} do not have that effect. The
-only way to set the value for the entire rule is with an ordinary action
-at the end of the rule.
-
-Here is an example from a hypothetical compiler, handling a @code{let}
-statement that looks like @samp{let (@var{variable}) @var{statement}} and
-serves to create a variable named @var{variable} temporarily for the
-duration of @var{statement}. To parse this construct, we must put
-@var{variable} into the symbol table while @var{statement} is parsed, then
-remove it afterward. Here is how it is done:
-
-@example
-@group
-stmt: LET '(' var ')'
- @{ $<context>$ = push_context ();
- declare_variable ($3); @}
- stmt @{ $$ = $6;
- pop_context ($<context>5); @}
-@end group
-@end example
-
-@noindent
-As soon as @samp{let (@var{variable})} has been recognized, the first
-action is run. It saves a copy of the current semantic context (the
-list of accessible variables) as its semantic value, using alternative
-@code{context} in the data-type union. Then it calls
-@code{declare_variable} to add the new variable to that list. Once the
-first action is finished, the embedded statement @code{stmt} can be
-parsed. Note that the mid-rule action is component number 5, so the
-@samp{stmt} is component number 6.
-
-After the embedded statement is parsed, its semantic value becomes the
-value of the entire @code{let}-statement. Then the semantic value from the
-earlier action is used to restore the prior list of variables. This
-removes the temporary @code{let}-variable from the list so that it won't
-appear to exist while the rest of the program is parsed.
-
-@findex %destructor
-@cindex discarded symbols, mid-rule actions
-@cindex error recovery, mid-rule actions
-In the above example, if the parser initiates error recovery (@pxref{Error
-Recovery}) while parsing the tokens in the embedded statement @code{stmt},
-it might discard the previous semantic context @code{$<context>5} without
-restoring it.
-Thus, @code{$<context>5} needs a destructor (@pxref{Destructor Decl, , Freeing
-Discarded Symbols}).
-However, Bison currently provides no means to declare a destructor for a
-mid-rule action's semantic value.
-
-One solution is to bury the mid-rule action inside a nonterminal symbol and to
-declare a destructor for that symbol:
-
-@example
-@group
-%type <context> let
-%destructor @{ pop_context ($$); @} let
-
-%%
-
-stmt: let stmt
- @{ $$ = $2;
- pop_context ($1); @}
- ;
-
-let: LET '(' var ')'
- @{ $$ = push_context ();
- declare_variable ($3); @}
- ;
-
-@end group
-@end example
-
-@noindent
-Note that the action is now at the end of its rule.
-Any mid-rule action can be converted to an end-of-rule action in this way, and
-this is what Bison actually does to implement mid-rule actions.
-
-Taking action before a rule is completely recognized often leads to
-conflicts since the parser must commit to a parse in order to execute the
-action. For example, the following two rules, without mid-rule actions,
-can coexist in a working parser because the parser can shift the open-brace
-token and look at what follows before deciding whether there is a
-declaration or not:
-
-@example
-@group
-compound: '@{' declarations statements '@}'
- | '@{' statements '@}'
- ;
-@end group
-@end example
-
-@noindent
-But when we add a mid-rule action as follows, the rules become nonfunctional:
-
-@example
-@group
-compound: @{ prepare_for_local_variables (); @}
- '@{' declarations statements '@}'
-@end group
-@group
- | '@{' statements '@}'
- ;
-@end group
-@end example
-
-@noindent
-Now the parser is forced to decide whether to run the mid-rule action
-when it has read no farther than the open-brace. In other words, it
-must commit to using one rule or the other, without sufficient
-information to do it correctly. (The open-brace token is what is called
-the @dfn{look-ahead} token at this time, since the parser is still
-deciding what to do about it. @xref{Look-Ahead, ,Look-Ahead Tokens}.)
-
-You might think that you could correct the problem by putting identical
-actions into the two rules, like this:
-
-@example
-@group
-compound: @{ prepare_for_local_variables (); @}
- '@{' declarations statements '@}'
- | @{ prepare_for_local_variables (); @}
- '@{' statements '@}'
- ;
-@end group
-@end example
-
-@noindent
-But this does not help, because Bison does not realize that the two actions
-are identical. (Bison never tries to understand the C code in an action.)
-
-If the grammar is such that a declaration can be distinguished from a
-statement by the first token (which is true in C), then one solution which
-does work is to put the action after the open-brace, like this:
-
-@example
-@group
-compound: '@{' @{ prepare_for_local_variables (); @}
- declarations statements '@}'
- | '@{' statements '@}'
- ;
-@end group
-@end example
-
-@noindent
-Now the first token of the following declaration or statement,
-which would in any case tell Bison which rule to use, can still do so.
-
-Another solution is to bury the action inside a nonterminal symbol which
-serves as a subroutine:
-
-@example
-@group
-subroutine: /* empty */
- @{ prepare_for_local_variables (); @}
- ;
-
-@end group
-
-@group
-compound: subroutine
- '@{' declarations statements '@}'
- | subroutine
- '@{' statements '@}'
- ;
-@end group
-@end example
-
-@noindent
-Now Bison can execute the action in the rule for @code{subroutine} without
-deciding which rule for @code{compound} it will eventually use.

-Though grammar rules and semantic actions are enough to write a fully

-@subsection Data Type of Locations
-@cindex data type of locations
-@cindex default location type
-
-Defining a data type for locations is much simpler than for semantic values,
-since all tokens and groupings always use the same type.
-
-You can specify the type of locations by defining a macro called
-@code{YYLTYPE}, just as you can specify the semantic value type by
-defining @code{YYSTYPE} (@pxref{Value Type}).
-When @code{YYLTYPE} is not defined, Bison uses a default structure type with
-four members:
-
-@example
-typedef struct YYLTYPE
-@{
- int first_line;
- int first_column;
- int last_line;
- int last_column;
-@} YYLTYPE;
-@end example
-
-@node Actions and Locations
-@subsection Actions and Locations
-@cindex location actions
-@cindex actions, location
-@vindex @@$
-@vindex @@@var{n}
-
-Actions are not only useful for defining language semantics, but also for
-describing the behavior of the output parser with locations.
-
-The most obvious way for building locations of syntactic groupings is very
-similar to the way semantic values are computed. In a given rule, several
-constructs can be used to access the locations of the elements being matched.
-The location of the @var{n}th component of the right hand side is
-@code{@@@var{n}}, while the location of the left hand side grouping is
-@code{@@$}.
-
-Here is a basic example using the default data type for locations:
-
-@example
-@group
-exp: @dots{}
- | exp '/' exp
- @{
- @@$.first_column = @@1.first_column;
- @@$.first_line = @@1.first_line;
- @@$.last_column = @@3.last_column;
- @@$.last_line = @@3.last_line;
- if ($3)
- $$ = $1 / $3;
- else
- @{
- $$ = 1;
- fprintf (stderr,
- "Division by zero, l%d,c%d-l%d,c%d",
- @@3.first_line, @@3.first_column,
- @@3.last_line, @@3.last_column);
- @}
- @}
-@end group
-@end example
-
-As for semantic values, there is a default action for locations that is
-run each time a rule is matched. It sets the beginning of @code{@@$} to the
-beginning of the first symbol, and the end of @code{@@$} to the end of the
-last symbol.
-
-With this default action, the location tracking can be fully automatic. The
-example above simply rewrites this way:
-
-@example
-@group
-exp: @dots{}
- | exp '/' exp
- @{
- if ($3)
- $$ = $1 / $3;
- else
- @{
- $$ = 1;
- fprintf (stderr,

- @@3.last_line, @@3.last_column);
- @}

-@end group

-
-@vindex yylloc

-from a semantic action.
-This location is stored in @code{yylloc}.

-
-@node Location Default Action
-@subsection Default Action for Locations
-@vindex YYLLOC_DEFAULT
-@cindex @acronym{GLR} parsers and @code{YYLLOC_DEFAULT}
-
-Actually, actions are not the best place to compute locations. Since
-locations are much more general than semantic values, there is room in
-the output parser to redefine the default action to take for each
-rule. The @code{YYLLOC_DEFAULT} macro is invoked each time a rule is
-matched, before the associated action is run. It is also invoked
-while processing a syntax error, to compute the error's location.
-Before reporting an unresolvable syntactic ambiguity, a @acronym{GLR}
-parser invokes @code{YYLLOC_DEFAULT} recursively to compute the location
-of that ambiguity.
-
-Most of the time, this macro is general enough to suppress location
-dedicated code from semantic actions.
-
-The @code{YYLLOC_DEFAULT} macro takes three parameters. The first one is
-the location of the grouping (the result of the computation). When a
-rule is matched, the second parameter identifies locations of
-all right hand side elements of the rule being matched, and the third
-parameter is the size of the rule's right hand side.
-When a @acronym{GLR} parser reports an ambiguity, which of multiple candidate
-right hand sides it passes to @code{YYLLOC_DEFAULT} is undefined.
-When processing a syntax error, the second parameter identifies locations
-of the symbols that were discarded during error processing, and the third
-parameter is the number of discarded symbols.
-
-By default, @code{YYLLOC_DEFAULT} is defined this way:
-
-@smallexample
-@group
-# define YYLLOC_DEFAULT(Current, Rhs, N) \
- do \
- if (N) \
- @{ \
- (Current).first_line = YYRHSLOC(Rhs, 1).first_line; \
- (Current).first_column = YYRHSLOC(Rhs, 1).first_column; \
- (Current).last_line = YYRHSLOC(Rhs, N).last_line; \
- (Current).last_column = YYRHSLOC(Rhs, N).last_column; \
- @} \
- else \
- @{ \
- (Current).first_line = (Current).last_line = \
- YYRHSLOC(Rhs, 0).last_line; \
- (Current).first_column = (Current).last_column = \
- YYRHSLOC(Rhs, 0).last_column; \
- @} \
- while (0)
-@end group
-@end smallexample
-
-where @code{YYRHSLOC (rhs, k)} is the location of the @var{k}th symbol
-in @var{rhs} when @var{k} is positive, and the location of the symbol
-just before the reduction when @var{k} and @var{n} are both zero.
-
-When defining @code{YYLLOC_DEFAULT}, you should consider that:
-
-@itemize @bullet
-@item
-All arguments are free of side-effects. However, only the first one (the
-result) should be modified by @code{YYLLOC_DEFAULT}.
-
-@item
-For consistency with semantic actions, valid indexes within the
-right hand side range from 1 to @var{n}. When @var{n} is zero, only 0 is a
-valid index, and it refers to the symbol just before the reduction.
-During error processing @var{n} is always positive.
-
-@item
-Your macro should parenthesize its arguments, if need be, since the
-actual arguments may not be surrounded by parentheses. Also, your
-macro should expand to something that can be used as a single

-@cindex declaring token type names

-@cindex declaring literal string tokens
-@findex %token
-
-The basic way to declare a token type name (terminal symbol) is as follows:
-
-@example
-%token @var{name}
-@end example
-
-Bison will convert this into a @code{#define} directive in
-the parser, so that the function @code{yylex} (if it is in this file)
-can use the name @var{name} to stand for this token type's code.
-
-Alternatively, you can use @code{%left}, @code{%right}, or
-@code{%nonassoc} instead of @code{%token}, if you wish to specify
-associativity and precedence. @xref{Precedence Decl, ,Operator
-Precedence}.
-
-You can explicitly specify the numeric code for a token type by appending
-a decimal or hexadecimal integer value in the field immediately
-following the token name:
-
-@example
-%token NUM 300
-%token XNUM 0x12d // a GNU extension
-@end example
-
-@noindent
-It is generally best, however, to let Bison choose the numeric codes for
-all token types. Bison will automatically select codes that don't conflict
-with each other or with normal characters.
-
-In the event that the stack type is a union, you must augment the
-@code{%token} or other token declaration to include the data type
-alternative delimited by angle-brackets (@pxref{Multiple Types, ,More
-Than One Value Type}).
-
-For example:
-
-@example
-@group
-%union @{ /* define stack type */
- double val;
- symrec *tptr;
-@}
-%token <val> NUM /* define token NUM and its type */
-@end group
-@end example
-
-You can associate a literal string token with a token type name by
-writing the literal string at the end of a @code{%token}
-declaration which declares the name. For example:
-
-@example
-%token arrow "=>"
-@end example
-
-@noindent
-For example, a grammar for the C language might specify these names with
-equivalent literal string tokens:
-
-@example
-%token <operator> OR "||"
-%token <operator> LE 134 "<="
-%left OR "<="
-@end example
-
-@noindent
-Once you equate the literal string and the token name, you can use them
-interchangeably in further declarations or the grammar rules. The
-@code{yylex} function can use the token name or the literal string to
-obtain the token type code number (@pxref{Calling Convention}).

-@example
-%left <@var{type}> @var{symbols}@dots{}

-
-And indeed any of these declarations serves the purposes of @code{%token}.
-But in addition, they specify the associativity and relative precedence for
-all the @var{symbols}:
-
-@itemize @bullet
-@item
-The associativity of an operator @var{op} determines how repeated uses
-of the operator nest: whether @samp{@var{x} @var{op} @var{y} @var{op}
-@var{z}} is parsed by grouping @var{x} with @var{y} first or by
-grouping @var{y} with @var{z} first. @code{%left} specifies
-left-associativity (grouping @var{x} with @var{y} first) and
-@code{%right} specifies right-associativity (grouping @var{y} with
-@var{z} first). @code{%nonassoc} specifies no associativity, which
-means that @samp{@var{x} @var{op} @var{y} @var{op} @var{z}} is
-considered a syntax error.
-
-@item
-The precedence of an operator determines how it nests with other operators.
-All the tokens declared in a single precedence declaration have equal
-precedence and nest together according to their associativity.
-When two tokens declared in different precedence declarations associate,

-
-@example
-@group
-%union @{

-This says that the two alternative types are @code{double} and @code{symrec

-As an extension to @acronym{POSIX}, a tag is allowed after the
-@code{union}. For example:

-@group
-%union value @{
- double val;
- symrec *tptr;
-@}
-@end group
-@end example
-
-@noindent
-specifies the union tag @code{value}, so the corresponding C type is
-@code{union value}. If you do not specify a tag, it defaults to
-@code{YYSTYPE}.
-
-As another extension to @acronym{POSIX}, you may specify multiple
-@code{%union} declarations; their contents are concatenated. However,
-only the first @code{%union} declaration can specify a tag.
-
-Note that, unlike making a @code{union} declaration in C, you need not write
-a semicolon after the closing brace.

-@node Type Decl
-@subsection Nonterminal Symbols
-@cindex declaring value types, nonterminals
-@cindex value types, nonterminals, declaring
-@findex %type
-
-@noindent
-When you use @code{%union} to specify multiple value types, you must
-declare the value type of each nonterminal symbol for which values are
-used. This is done with a @code{%type} declaration, like this:
-
-@example
-%type <@var{type}> @var{nonterminal}@dots{}
-@end example
-
-@noindent
-Here @var{nonterminal} is the name of a nonterminal symbol, and
-@var{type} is the name given in the @code{%union} to the alternative
-that you want (@pxref{Union Decl, ,The Collection of Value Types}). You
-can give any number of nonterminal symbols in the same @code{%type}
-declaration, if they have the same value type. Use spaces to separate
-the symbol names.
-
-You can also declare the value type of a terminal symbol. To do this,
-use the same @code{<@var{type}>} construction in a declaration for the
-terminal symbol. All kinds of token declarations allow
-@code{<@var{type}>}.
-
-@node Initial Action Decl
-@subsection Performing Actions before Parsing
-@findex %initial-action
-
-Sometimes your parser needs to perform some initializations before
-parsing. The @code{%initial-action} directive allows for such arbitrary
-code.
-
-@deffn {Directive} %initial-action @{ @var{code} @}
-@findex %initial-action
-Declare that the braced @var{code} must be invoked before parsing each time
-@code{yyparse} is called. The @var{code} may use @code{$$} and
-@code{@@$} --- initial value and location of the look-ahead --- and the
-@code{%parse-param}.
-@end deffn
-
-For instance, if your locations use a file name, you may use
-
-@example
-%parse-param @{ char const *file_name @};
-%initial-action
-@{
- @@$.initialize (file_name);
-@};
-@end example
-
-
-@node Destructor Decl
-@subsection Freeing Discarded Symbols
-@cindex freeing discarded symbols
-@findex %destructor
-
-During error recovery (@pxref{Error Recovery}), symbols already pushed
-on the stack and tokens coming from the rest of the file are discarded
-until the parser falls on its feet. If the parser runs out of memory,
-or if it returns via @code{YYABORT} or @code{YYACCEPT}, all the
-symbols on the stack must be discarded. Even if the parser succeeds, it
-must discard the start symbol.
-
-When discarded symbols convey heap based information, this memory is
-lost. While this behavior can be tolerable for batch parsers, such as
-in traditional compilers, it is unacceptable for programs like shells or
-protocol implementations that may parse and execute indefinitely.
-
-The @code{%destructor} directive defines code that is called when a
-symbol is automatically discarded.
-
-@deffn {Directive} %destructor @{ @var{code} @} @var{symbols}
-@findex %destructor
-Invoke the braced @var{code} whenever the parser discards one of the
-@var{symbols}.
-Within @var{code}, @code{$$} designates the semantic value associated
-with the discarded symbol. The additional parser parameters are also
-available (@pxref{Parser Function, , The Parser Function
-@code{yyparse}}).
-@end deffn
-
-For instance:
-
-@smallexample
-%union
-@{
- char *string;
-@}
-%token <string> STRING
-%type <string> string
-%destructor @{ free ($$); @} STRING string
-@end smallexample
-
-@noindent
-guarantees that when a @code{STRING} or a @code{string} is discarded,
-its associated memory will be freed.
-
-@sp 1
-
-@cindex discarded symbols
-@dfn{Discarded symbols} are the following:
-
-@itemize
-@item
-stacked symbols popped during the first phase of error recovery,
-@item
-incoming terminals during the second phase of error recovery,
-@item
-the current look-ahead and the entire stack (except the current
-right-hand side symbols) when the parser returns immediately, and
-@item
-the start symbol, when the parser succeeds.
-@end itemize
-
-The parser can @dfn{return immediately} because of an explicit call to
-@code{YYABORT} or @code{YYACCEPT}, or failed error recovery, or memory
-exhaustion.
-
-Right-hand size symbols of a rule that explicitly triggers a syntax
-error via @code{YYERROR} are not discarded automatically. As a rule
-of thumb, destructors are invoked only when user actions cannot manage
-the memory.

-@node Expect Decl
-@subsection Suppressing Conflict Warnings
-@cindex suppressing conflict warnings
-@cindex preventing warnings about conflicts
-@cindex warnings, preventing
-@cindex conflicts, suppressing warnings of
-@findex %expect
-@findex %expect-rr
-
-Bison normally warns if there are any conflicts in the grammar
-(@pxref{Shift/Reduce, ,Shift/Reduce Conflicts}), but most real grammars
-have harmless shift/reduce conflicts which are resolved in a predictable
-way and would be difficult to eliminate. It is desirable to suppress
-the warning about these conflicts unless the number of conflicts
-changes. You can do this with the @code{%expect} declaration.
-
-The declaration looks like this:
-
-@example
-%expect @var{n}
-@end example
-
-Here @var{n} is a decimal integer. The declaration says there should
-be @var{n} shift/reduce conflicts and no reduce/reduce conflicts.
-Bison reports an error if the number of shift/reduce conflicts differs
-from @var{n}, or if there are any reduce/reduce conflicts.
-
-For normal @acronym{LALR}(1) parsers, reduce/reduce conflicts are more
-serious, and should be eliminated entirely. Bison will always report
-reduce/reduce conflicts for these parsers. With @acronym{GLR}
-parsers, however, both kinds of conflicts are routine; otherwise,
-there would be no need to use @acronym{GLR} parsing. Therefore, it is
-also possible to specify an expected number of reduce/reduce conflicts
-in @acronym{GLR} parsers, using the declaration:
-
-@example
-%expect-rr @var{n}
-@end example
-
-In general, using @code{%expect} involves these steps:
-
-@itemize @bullet
-@item
-Compile your grammar without @code{%expect}. Use the @samp{-v} option
-to get a verbose list of where the conflicts occur. Bison will also
-print the number of conflicts.
-
-@item
-Check each of the conflicts to make sure that Bison's default
-resolution is what you really want. If not, rewrite the grammar and
-go back to the beginning.
-
-@item
-Add an @code{%expect} declaration, copying the number @var{n} from the
-number which Bison printed. With @acronym{GLR} parsers, add an
-@code{%expect-rr} declaration as well.
-@end itemize
-
-Now Bison will warn you if you introduce an unexpected conflict, but
-will keep silent otherwise.
-
-@node Start Decl
-@subsection The Start-Symbol
-@cindex declaring the start symbol
-@cindex start symbol, declaring
-@cindex default start symbol
-@findex %start
-
-Bison assumes by default that the start symbol for the grammar is the first
-nonterminal specified in the grammar specification section. The programmer
-may override this restriction with the @code{%start} declaration as follows:
-
-@example
-%start @var{symbol}
-@end example
-
-@node Pure Decl
-@subsection A Pure (Reentrant) Parser
-@cindex reentrant parser
-@cindex pure parser
-@findex %pure-parser
-
-A @dfn{reentrant} program is one which does not alter in the course of
-execution; in other words, it consists entirely of @dfn{pure} (read-only)
-code. Reentrancy is important whenever asynchronous execution is possible;
-for example, a nonreentrant program may not be safe to call from a signal
-handler. In systems with multiple threads of control, a nonreentrant
-program must be called only within interlocks.
-
-Normally, Bison generates a parser which is not reentrant. This is
-suitable for most uses, and it permits compatibility with Yacc. (The
-standard Yacc interfaces are inherently nonreentrant, because they use
-statically allocated variables for communication with @code{yylex},
-including @code{yylval} and @code{yylloc}.)
-
-Alternatively, you can generate a pure, reentrant parser. The Bison
-declaration @code{%pure-parser} says that you want the parser to be
-reentrant. It looks like this:
-
-@example
-%pure-parser
-@end example
-
-The result is that the communication variables @code{yylval} and
-@code{yylloc} become local variables in @code{yyparse}, and a different
-calling convention is used for the lexical analyzer function
-@code{yylex}. @xref{Pure Calling, ,Calling Conventions for Pure
-Parsers}, for the details of this. The variable @code{yynerrs} also
-becomes local in @code{yyparse} (@pxref{Error Reporting, ,The Error
-Reporting Function @code{yyerror}}). The convention for calling
-@code{yyparse} itself is unchanged.
-
-Whether the parser is pure has nothing to do with the grammar rules.
-You can generate either a pure parser or a nonreentrant parser from any
-valid grammar.

-In order to change the behavior of @command{bison}, use the following

-@end deffn
-@xref{Tracing, ,Tracing Your Parser}.

-@deffn {Directive} %defines
-Write a header file containing macro definitions for the token type
-names defined in the grammar as well as a few other declarations.
-If the parser output file is named @file{@var{name}.c} then this file
-is named @file{@var{name}.h}.
-
-Unless @code{YYSTYPE} is already defined as a macro, the output header
-declares @code{YYSTYPE}. Therefore, if you are using a @code{%union}
-(@pxref{Multiple Types, ,More Than One Value Type}) with components that
-require other definitions, or if you have defined a @code{YYSTYPE} macro
-(@pxref{Value Type, ,Data Types of Semantic Values}), you need to
-arrange for these definitions to be propagated to all modules, e.g., by
-putting them in a prerequisite header that is included both by your
-parser and by any other module that needs @code{YYSTYPE}.
-
-Unless your parser is pure, the output header declares @code{yylval}
-as an external variable. @xref{Pure Decl, ,A Pure (Reentrant)

-
-If you have also used locations, the output header declares
-@code{YYLTYPE} and @code{yylloc} using a protocol similar to that of

-
-This output file is normally essential if you wish to put the definition

-Generate an array of token names in the parser file. The name of the
-array is @code{yytname}; @code{yytname[@var{i}]} is the name of the

-@node Multiple Parsers
-@section Multiple Parsers in the Same Program
-
-Most programs that use Bison parse only one language and therefore contain
-only one Bison parser. But what if you want to parse more than one
-language with the same program? Then you need to avoid a name conflict
-between different definitions of @code{yyparse}, @code{yylval}, and so on.
-
-The easy way to do this is to use the option @samp{-p @var{prefix}}
-(@pxref{Invocation, ,Invoking Bison}). This renames the interface
-functions and variables of the Bison parser to start with @var{prefix}
-instead of @samp{yy}. You can use this to give each parser distinct
-names that do not conflict.
-
-The precise list of symbols renamed is @code{yyparse}, @code{yylex},
-@code{yyerror}, @code{yynerrs}, @code{yylval}, @code{yylloc},
-@code{yychar} and @code{yydebug}. For example, if you use @samp{-p c},
-the names become @code{cparse}, @code{clex}, and so on.
-
-@strong{All the other variables and macros associated with Bison are not
-renamed.} These others are not global; there is no conflict if the same
-name is used in different parsers. For example, @code{YYSTYPE} is not
-renamed, but defining this in different ways in different parsers causes
-no trouble (@pxref{Value Type, ,Data Types of Semantic Values}).
-
-The @samp{-p} option works by adding macro definitions to the beginning
-of the parser source file, defining @code{yyparse} as
-@code{@var{prefix}parse}, and so on. This effectively substitutes one
-name for the other in the entire parser file.

-
-The Bison parser is actually a C function named @code{yyparse}. Here we
-describe the interface conventions of @code{yyparse} and the other
-functions that it needs to use.
-
-Keep in mind that the parser uses many C identifiers starting with
-@samp{yy} and @samp{YY} for internal purposes. If you use such an
-identifier (aside from those in this manual) in an action or in epilogue
-in the grammar file, you are likely to run into trouble.

-@end menu
-
-@node Parser Function
-@section The Parser Function @code{yyparse}
-@findex yyparse
-
-You call the function @code{yyparse} to cause parsing to occur. This
-function reads tokens, executes actions, and ultimately returns when it
-encounters end-of-input or an unrecoverable syntax error. You can also
-write an action which directs @code{yyparse} to return immediately
-without reading further.
-
-
-@deftypefun int yyparse (void)
-The value returned by @code{yyparse} is 0 if parsing was successful (return
-is due to end-of-input).
-
-The value is 1 if parsing failed because of invalid input, i.e., input
-that contains a syntax error or that causes @code{YYABORT} to be
-invoked.
-
-The value is 2 if parsing failed due to memory exhaustion.
-@end deftypefun
-
-In an action, you can cause immediate return from @code{yyparse} by using
-these macros:
-
-@defmac YYACCEPT
-@findex YYACCEPT
-Return immediately with value 0 (to report success).
-@end defmac
-
-@defmac YYABORT
-@findex YYABORT
-Return immediately with value 1 (to report failure).
-@end defmac
-
-If you use a reentrant parser, you can optionally pass additional
-parameter information to it in a reentrant way. To do so, use the
-declaration @code{%parse-param}:
-
-@deffn {Directive} %parse-param @{@var{argument-declaration}@}
-@findex %parse-param
-Declare that an argument declared by the braced-code
-@var{argument-declaration} is an additional @code{yyparse} argument.
-The @var{argument-declaration} is used when declaring
-functions or prototypes. The last identifier in
-@var{argument-declaration} must be the argument name.
-@end deffn
-
-Here's an example. Write this in the parser:
-
-@example
-%parse-param @{int *nastiness@}
-%parse-param @{int *randomness@}
-@end example
-
-@noindent
-Then call the parser like this:
-
-@example
-@{
- int nastiness, randomness;
- @dots{} /* @r{Store proper data in @code{nastiness} and @code{randomness}.} */
- value = yyparse (&nastiness, &randomness);
- @dots{}
-@}
-@end example
-
-@noindent
-In the grammar actions, use expressions like this to refer to the data:
-
-@example
-exp: @dots{} @{ @dots{}; *randomness += 1; @dots{} @}
-@end example
-
-
-@node Lexical
-@section The Lexical Analyzer Function @code{yylex}
-@findex yylex
-@cindex lexical analyzer
-
-The @dfn{lexical analyzer} function, @code{yylex}, recognizes tokens from
-the input stream and returns them to the parser. Bison does not create
-this function automatically; you must write it so that @code{yyparse} can
-call it. The function is sometimes referred to as a lexical scanner.
-
-In simple programs, @code{yylex} is often defined at the end of the Bison
-grammar file. If @code{yylex} is defined in a separate source file, you
-need to arrange for the token-type macro definitions to be available there.
-To do this, use the @samp{-d} option when you run Bison, so that it will
-write these macro definitions into a separate header file
-@file{@var{name}.tab.h} which you can include in the other source files
-that need it. @xref{Invocation, ,Invoking Bison}.
-
-@menu
-* Calling Convention:: How @code{yyparse} calls @code{yylex}.
-* Token Values:: How @code{yylex} must return the semantic value
- of the token it has read.
-* Token Locations:: How @code{yylex} must return the text location
- (line number, etc.) of the token, if the
- actions want that.
-* Pure Calling:: How the calling convention differs
- in a pure parser (@pxref{Pure Decl, ,A Pure (Reentrant) Parser}).
-@end menu
-
-@node Calling Convention
-@subsection Calling Convention for @code{yylex}
-
-The value that @code{yylex} returns must be the positive numeric code
-for the type of token it has just found; a zero or negative value
-signifies end-of-input.
-
-When a token is referred to in the grammar rules by a name, that name
-in the parser file becomes a C macro whose definition is the proper
-numeric code for that token type. So @code{yylex} can use the name
-to indicate that type. @xref{Symbols}.
-
-When a token is referred to in the grammar rules by a character literal,
-the numeric code for that character is also the code for the token type.
-So @code{yylex} can simply return that character code, possibly converted
-to @code{unsigned char} to avoid sign-extension. The null character
-must not be used this way, because its code is zero and that
-signifies end-of-input.
-
-Here is an example showing these things:
-
-@example
-int
-yylex (void)
-@{
- @dots{}
- if (c == EOF) /* Detect end-of-input. */
- return 0;
- @dots{}
- if (c == '+' || c == '-')
- return c; /* Assume token type for `+' is '+'. */
- @dots{}
- return INT; /* Return the type of the token. */
- @dots{}
-@}
-@end example
-
-@noindent
-This interface has been designed so that the output from the @code{lex}
-utility can be used without change as the definition of @code{yylex}.
-
-If the grammar uses literal string tokens, there are two ways that
-@code{yylex} can determine the token type codes for them:
-
-@itemize @bullet
-@item
-If the grammar defines symbolic token names as aliases for the
-literal string tokens, @code{yylex} can use these symbolic names like
-all others. In this case, the use of the literal string tokens in
-the grammar file has no effect on @code{yylex}.
-
-@item
-@code{yylex} can find the multicharacter token in the @code{yytname}
-table. The index of the token in the table is the token type's code.
-The name of a multicharacter token is recorded in @code{yytname} with a
-double-quote, the token's characters, and another double-quote. The
-token's characters are escaped as necessary to be suitable as input

-@node Token Values
-@subsection Semantic Values of Tokens
-
-@vindex yylval
-In an ordinary (nonreentrant) parser, the semantic value of the token must
-be stored into the global variable @code{yylval}. When you are using
-just one data type for semantic values, @code{yylval} has that type.
-Thus, if the type is @code{int} (the default), you might write this in
-@code{yylex}:
-
-@example
-@group
- @dots{}
- yylval = value; /* Put value onto Bison stack. */
- return INT; /* Return the type of the token. */
- @dots{}
-@end group
-@end example
-
-When you are using multiple data types, @code{yylval}'s type is a union
-made from the @code{%union} declaration (@pxref{Union Decl, ,The
-Collection of Value Types}). So when you store a token's value, you
-must use the proper member of the union. If the @code{%union}
-declaration looks like this:
-
-@example
-@group
-%union @{
- int intval;
- double val;
- symrec *tptr;
-@}
-@end group
-@end example
-
-@noindent
-then the code in @code{yylex} might look like this:
-
-@example
-@group
- @dots{}
- yylval.intval = value; /* Put value onto Bison stack. */
- return INT; /* Return the type of the token. */
- @dots{}
-@end group
-@end example
-
-@node Token Locations
-@subsection Textual Locations of Tokens
-
-@vindex yylloc
-If you are using the @samp{@@@var{n}}-feature (@pxref{Locations, ,
-Tracking Locations}) in actions to keep track of the textual locations
-of tokens and groupings, then you must provide this information in
-@code{yylex}. The function @code{yyparse} expects to find the textual
-location of a token just parsed in the global variable @code{yylloc}.
-So @code{yylex} must store the proper data in that variable.
-
-By default, the value of @code{yylloc} is a structure and you need only
-initialize the members that are going to be used by the actions. The
-four members are called @code{first_line}, @code{first_column},
-@code{last_line} and @code{last_column}. Note that the use of this
-feature makes the parser noticeably slower.
-
-@tindex YYLTYPE
-The data type of @code{yylloc} has the name @code{YYLTYPE}.
-
-@node Pure Calling
-@subsection Calling Conventions for Pure Parsers
-
-When you use the Bison declaration @code{%pure-parser} to request a
-pure, reentrant parser, the global communication variables @code{yylval}
-and @code{yylloc} cannot be used. (@xref{Pure Decl, ,A Pure (Reentrant)
-Parser}.) In such parsers the two global variables are replaced by
-pointers passed as arguments to @code{yylex}. You must declare them as
-shown here, and pass the information back by storing it through those
-pointers.
-
-@example
-int
-yylex (YYSTYPE *lvalp, YYLTYPE *llocp)
-@{
- @dots{}
- *lvalp = value; /* Put value onto Bison stack. */
- return INT; /* Return the type of the token. */
- @dots{}
-@}
-@end example
-
-If the grammar file does not use the @samp{@@} constructs to refer to
-textual locations, then the type @code{YYLTYPE} will not be defined. In
-this case, omit the second argument; @code{yylex} will be called with
-only one argument.
-
-
-If you wish to pass the additional parameter data to @code{yylex}, use
-@code{%lex-param} just like @code{%parse-param} (@pxref{Parser
-Function}).
-
-@deffn {Directive} lex-param @{@var{argument-declaration}@}
-@findex %lex-param
-Declare that the braced-code @var{argument-declaration} is an
-additional @code{yylex} argument declaration.
-@end deffn
-
-For instance:
-
-@example
-%parse-param @{int *nastiness@}
-%lex-param @{int *nastiness@}
-%parse-param @{int *randomness@}
-@end example
-
-@noindent
-results in the following signature:
-
-@example
-int yylex (int *nastiness);
-int yyparse (int *nastiness, int *randomness);
-@end example
-
-If @code{%pure-parser} is added:
-
-@example
-int yylex (YYSTYPE *lvalp, int *nastiness);
-int yyparse (int *nastiness, int *randomness);
-@end example
-
-@noindent
-and finally, if both @code{%pure-parser} and @code{%locations} are used:
-
-@example
-int yylex (YYSTYPE *lvalp, YYLTYPE *llocp, int *nastiness);
-int yyparse (int *nastiness, int *randomness);
-@end example
-
-@node Error Reporting
-@section The Error Reporting Function @code{yyerror}
-@cindex error reporting function
-@findex yyerror
-@cindex parse error
-@cindex syntax error
-
-The Bison parser detects a @dfn{syntax error} or @dfn{parse error}
-whenever it reads a token which cannot satisfy any syntax rule. An
-action in the grammar can also explicitly proclaim an error, using the
-macro @code{YYERROR} (@pxref{Action Features, ,Special Features for Use
-in Actions}).
-
-The Bison parser expects to report the error by calling an error
-reporting function named @code{yyerror}, which you must supply. It is
-called by @code{yyparse} whenever a syntax error is found, and it
-receives one argument. For a syntax error, the string is normally
-@w{@code{"syntax error"}}.
-
-@findex %error-verbose
-If you invoke the directive @code{%error-verbose} in the Bison
-declarations section (@pxref{Bison Declarations, ,The Bison Declarations
-Section}), then Bison provides a more verbose and specific error message
-string instead of just plain @w{@code{"syntax error"}}.
-
-The parser can detect one other kind of error: memory exhaustion. This
-can happen when the input contains constructions that are very deeply
-nested. It isn't likely you will encounter this, since the Bison
-parser normally extends its stack automatically up to a very large limit. But
-if memory is exhausted, @code{yyparse} calls @code{yyerror} in the usual
-fashion, except that the argument string is @w{@code{"memory exhausted"}}.
-
-In some cases diagnostics like @w{@code{"syntax error"}} are
-translated automatically from English to some other language before
-they are passed to @code{yyerror}. @xref{Internationalization}.
-
-The following definition suffices in simple programs:
-
-@example
-@group
-void
-yyerror (char const *s)
-@{
-@end group
-@group
- fprintf (stderr, "%s\n", s);
-@}
-@end group
-@end example
-
-After @code{yyerror} returns to @code{yyparse}, the latter will attempt
-error recovery if you have written suitable error recovery grammar rules
-(@pxref{Error Recovery}). If recovery is impossible, @code{yyparse} will
-immediately return 1.
-
-Obviously, in location tracking pure parsers, @code{yyerror} should have
-an access to the current location.
-This is indeed the case for the @acronym{GLR}
-parsers, but not for the Yacc parser, for historical reasons. I.e., if
-@samp{%locations %pure-parser} is passed then the prototypes for
-@code{yyerror} are:
-
-@example
-void yyerror (char const *msg); /* Yacc parsers. */
-void yyerror (YYLTYPE *locp, char const *msg); /* GLR parsers. */
-@end example
-
-If @samp{%parse-param @{int *nastiness@}} is used, then:
-
-@example
-void yyerror (int *nastiness, char const *msg); /* Yacc parsers. */
-void yyerror (int *nastiness, char const *msg); /* GLR parsers. */
-@end example
-
-Finally, @acronym{GLR} and Yacc parsers share the same @code{yyerror} calling
-convention for absolutely pure parsers, i.e., when the calling
-convention of @code{yylex} @emph{and} the calling convention of
-@code{%pure-parser} are pure. I.e.:
-
-@example
-/* Location tracking. */
-%locations
-/* Pure yylex. */
-%pure-parser
-%lex-param @{int *nastiness@}
-/* Pure yyparse. */
-%parse-param @{int *nastiness@}
-%parse-param @{int *randomness@}
-@end example
-
-@noindent
-results in the following signatures for all the parser kinds:
-
-@example
-int yylex (YYSTYPE *lvalp, YYLTYPE *llocp, int *nastiness);
-int yyparse (int *nastiness, int *randomness);
-void yyerror (YYLTYPE *locp,
- int *nastiness, int *randomness,
- char const *msg);
-@end example
-
-@noindent
-The prototypes are only indications of how the code produced by Bison
-uses @code{yyerror}. Bison-generated code always ignores the returned
-value, so @code{yyerror} can return any type, including @code{void}.
-Also, @code{yyerror} can be a variadic function; that is why the
-message is always passed last.
-
-Traditionally @code{yyerror} returns an @code{int} that is always
-ignored, but this is purely for historical reasons, and @code{void} is
-preferable since it more accurately describes the return type for
-@code{yyerror}.
-
-@vindex yynerrs
-The variable @code{yynerrs} contains the number of syntax errors
-reported so far. Normally this variable is global; but if you
-request a pure parser (@pxref{Pure Decl, ,A Pure (Reentrant) Parser})
-then it is a local variable which only the actions can access.

-A Bison-generated parser can print diagnostics, including error and

-
-The maintainer of a package that uses a Bison-generated parser enables
-the internationalization of the parser's output through the following

-causes @samp{configure} to find the value of the
-@code{BISON_LOCALEDIR} variable, and it defines the source-language
-symbol @code{YYENABLE_NLS} to enable translations in the
-Bison-generated parser.
-
-@item
-In the @code{main} function of your program, designate the directory

-@cindex shifting
-@cindex reduction
-@cindex parser stack
-@cindex stack, parser
-
-As Bison reads tokens, it pushes them onto a stack along with their
-semantic values. The stack is called the @dfn{parser stack}. Pushing a
-token is traditionally called @dfn{shifting}.
-
-For example, suppose the infix calculator has read @samp{1 + 5 *}, with a
-@samp{3} to come. The stack will have four elements, one for each token
-that was shifted.
-
-But the stack does not always have an element for each token read. When
-the last @var{n} tokens and groupings shifted match the components of a
-grammar rule, they can be combined according to that rule. This is called
-@dfn{reduction}. Those tokens and groupings are replaced on the stack by a
-single grouping whose symbol is the result (left hand side) of that rule.
-Running the rule's action is part of the process of reduction, because this
-is what computes the semantic value of the resulting grouping.
-
-For example, if the infix calculator's parser stack contains this:
-
-@example
-1 + 5 * 3
-@end example
-
-@noindent
-and the next input token is a newline character, then the last three
-elements can be reduced to 15 via the rule:
-
-@example
-expr: expr '*' expr;
-@end example
-
-@noindent
-Then the stack contains just these three elements:
-
-@example
-1 + 15
-@end example
-
-@noindent
-At this point, another reduction can be made, resulting in the single value
-16. Then the newline token can be shifted.
-
-The parser tries, by shifts and reductions, to reduce the entire input down
-to a single grouping whose symbol is the grammar's start-symbol
-(@pxref{Language and Grammar, ,Languages and Context-Free Grammars}).
-
-This kind of parser is known in the literature as a bottom-up parser.

-@node Look-Ahead
-@section Look-Ahead Tokens
-@cindex look-ahead token
-
-The Bison parser does @emph{not} always reduce immediately as soon as the
-last @var{n} tokens and groupings match a rule. This is because such a
-simple strategy is inadequate to handle most languages. Instead, when a
-reduction is possible, the parser sometimes ``looks ahead'' at the next
-token in order to decide what to do.
-
-When a token is read, it is not immediately shifted; first it becomes the
-@dfn{look-ahead token}, which is not on the stack. Now the parser can
-perform one or more reductions of tokens and groupings on the stack, while
-the look-ahead token remains off to the side. When no more reductions
-should take place, the look-ahead token is shifted onto the stack. This
-does not mean that all possible reductions have been done; depending on the
-token type of the look-ahead token, some rules may choose to delay their
-application.
-
-Here is a simple case where look-ahead is needed. These three rules define
-expressions which contain binary addition operators and postfix unary
-factorial operators (@samp{!}), and allow parentheses for grouping.
-
-@example
-@group
-expr: term '+' expr
- | term
- ;
-@end group
-
-@group
-term: '(' expr ')'
- | term '!'
- | NUMBER
- ;
-@end group
-@end example
-
-Suppose that the tokens @w{@samp{1 + 2}} have been read and shifted; what
-should be done? If the following token is @samp{)}, then the first three
-tokens must be reduced to form an @code{expr}. This is the only valid
-course, because shifting the @samp{)} would produce a sequence of symbols
-@w{@code{term ')'}}, and no rule allows this.
-
-If the following token is @samp{!}, then it must be shifted immediately so
-that @w{@samp{2 !}} can be reduced to make a @code{term}. If instead the
-parser were to reduce before shifting, @w{@samp{1 + 2}} would become an
-@code{expr}. It would then be impossible to shift the @samp{!} because
-doing so would produce on the stack the sequence of symbols @code{expr
-'!'}. No rule allows that sequence.

-@node Shift/Reduce
-@section Shift/Reduce Conflicts
-@cindex conflicts
-@cindex shift/reduce conflicts
-@cindex dangling @code{else}
-@cindex @code{else}, dangling
-
-Suppose we are parsing a language which has if-then and if-then-else
-statements, with a pair of rules like this:
-
-@example
-@group
-if_stmt:
- IF expr THEN stmt
- | IF expr THEN stmt ELSE stmt
- ;
-@end group
-@end example
-
-@noindent
-Here we assume that @code{IF}, @code{THEN} and @code{ELSE} are
-terminal symbols for specific keyword tokens.
-
-When the @code{ELSE} token is read and becomes the look-ahead token, the
-contents of the stack (assuming the input is valid) are just right for
-reduction by the first rule. But it is also legitimate to shift the
-@code{ELSE}, because that would lead to eventual reduction by the second
-rule.
-
-This situation, where either a shift or a reduction would be valid, is
-called a @dfn{shift/reduce conflict}. Bison is designed to resolve
-these conflicts by choosing to shift, unless otherwise directed by
-operator precedence declarations. To see the reason for this, let's
-contrast it with the other alternative.
-
-Since the parser prefers to shift the @code{ELSE}, the result is to attach
-the else-clause to the innermost if-statement, making these two inputs
-equivalent:
-
-@example
-if x then if y then win (); else lose;
-
-if x then do; if y then win (); else lose; end;
-@end example
-
-But if the parser chose to reduce when possible rather than shift, the
-result would be to attach the else-clause to the outermost if-statement,
-making these two inputs equivalent:
-
-@example
-if x then if y then win (); else lose;
-
-if x then do; if y then win (); end; else lose;
-@end example
-
-The conflict exists because the grammar as written is ambiguous: either
-parsing of the simple nested if-statement is legitimate. The established
-convention is that these ambiguities are resolved by attaching the
-else-clause to the innermost if-statement; this is what Bison accomplishes
-by choosing to shift rather than reduce. (It would ideally be cleaner to
-write an unambiguous grammar, but that is very hard to do in this case.)
-This particular ambiguity was first encountered in the specifications of
-Algol 60 and is called the ``dangling @code{else}'' ambiguity.
-

-@node Why Precedence
-@subsection When Precedence is Needed
-
-Consider the following ambiguous grammar fragment (ambiguous because the
-input @w{@samp{1 - 2 * 3}} can be parsed in two different ways):
-
-@example
-@group
-expr: expr '-' expr
- | expr '*' expr
- | expr '<' expr
- | '(' expr ')'
- @dots{}
- ;
-@end group
-@end example
-
-@noindent
-Suppose the parser has seen the tokens @samp{1}, @samp{-} and @samp{2};
-should it reduce them via the rule for the subtraction operator? It
-depends on the next token. Of course, if the next token is @samp{)}, we
-must reduce; shifting is invalid because no single rule can reduce the
-token sequence @w{@samp{- 2 )}} or anything starting with that. But if
-the next token is @samp{*} or @samp{<}, we have a choice: either
-shifting or reduction would allow the parse to complete, but with
-different results.
-
-To decide which one Bison should do, we must consider the results. If
-the next operator token @var{op} is shifted, then it must be reduced
-first in order to permit another opportunity to reduce the difference.
-The result is (in effect) @w{@samp{1 - (2 @var{op} 3)}}. On the other
-hand, if the subtraction is reduced before shifting @var{op}, the result
-is @w{@samp{(1 - 2) @var{op} 3}}. Clearly, then, the choice of shift or
-reduce should depend on the relative precedence of the operators
-@samp{-} and @var{op}: @samp{*} should be shifted first, but not
-@samp{<}.
-
-@cindex associativity
-What about input such as @w{@samp{1 - 2 - 5}}; should this be
-@w{@samp{(1 - 2) - 5}} or should it be @w{@samp{1 - (2 - 5)}}? For most
-operators we prefer the former, which is called @dfn{left association}.
-The latter alternative, @dfn{right association}, is desirable for
-assignment operators. The choice of left or right association is a
-matter of whether the parser chooses to shift or reduce when the stack
-contains @w{@samp{1 - 2}} and the look-ahead token is @samp{-}: shifting
-makes right-associativity.
-
-@node Using Precedence
-@subsection Specifying Operator Precedence
-@findex %left
-@findex %right
-@findex %nonassoc
-
-Bison allows you to specify these choices with the operator precedence
-declarations @code{%left} and @code{%right}. Each such declaration
-contains a list of tokens, which are operators whose precedence and
-associativity is being declared. The @code{%left} declaration makes all
-those operators left-associative and the @code{%right} declaration makes
-them right-associative. A third alternative is @code{%nonassoc}, which
-declares that it is a syntax error to find the same operator twice ``in a
-row''.
-
-The relative precedence of different operators is controlled by the
-order in which they are declared. The first @code{%left} or
-@code{%right} declaration in the file declares the operators whose
-precedence is lowest, the next such declaration declares the operators
-whose precedence is a little higher, and so on.
-
-@node Precedence Examples
-@subsection Precedence Examples
-
-In our example, we would want the following declarations:
-
-@example
-%left '<'
-%left '-'
-%left '*'
-@end example
-
-In a more complete example, which supports other operators as well, we
-would declare them in groups of equal precedence. For example, @code{'+'} is
-declared with @code{'-'}:
-
-@example
-%left '<' '>' '=' NE LE GE
-%left '+' '-'
-%left '*' '/'
-@end example
-
-@noindent
-(Here @code{NE} and so on stand for the operators for ``not equal''
-and so on. We assume that these tokens are more than one character long
-and therefore are represented by names, not character literals.)
-
-@node How Precedence
-@subsection How Precedence Works
-
-The first effect of the precedence declarations is to assign precedence
-levels to the terminal symbols declared. The second effect is to assign
-precedence levels to certain rules: each rule gets its precedence from
-the last terminal symbol mentioned in the components. (You can also
-specify explicitly the precedence of a rule. @xref{Contextual
-Precedence, ,Context-Dependent Precedence}.)
-
-Finally, the resolution of conflicts works by comparing the precedence
-of the rule being considered with that of the look-ahead token. If the
-token's precedence is higher, the choice is to shift. If the rule's
-precedence is higher, the choice is to reduce. If they have equal
-precedence, the choice is made based on the associativity of that
-precedence level. The verbose output file made by @samp{-v}
-(@pxref{Invocation, ,Invoking Bison}) says how each conflict was
-resolved.
-
-Not all rules and not all tokens have precedence. If either the rule or
-the look-ahead token has no precedence, then the default is to shift.
-
-@node Contextual Precedence
-@section Context-Dependent Precedence
-@cindex context-dependent precedence
-@cindex unary operator precedence
-@cindex precedence, context-dependent
-@cindex precedence, unary operator
-@findex %prec
-
-Often the precedence of an operator depends on the context. This sounds
-outlandish at first, but it is really very common. For example, a minus
-sign typically has a very high precedence as a unary operator, and a
-somewhat lower precedence (lower than multiplication) as a binary operator.
-
-The Bison precedence declarations, @code{%left}, @code{%right} and
-@code{%nonassoc}, can only be used once for a given token; so a token has
-only one precedence declared in this way. For context-dependent
-precedence, you need to use an additional mechanism: the @code{%prec}
-modifier for rules.
-
-The @code{%prec} modifier declares the precedence of a particular rule by
-specifying a terminal symbol whose precedence should be used for that rule.
-It's not necessary for that symbol to appear otherwise in the rule. The
-modifier's syntax is:
-
-@example
-%prec @var{terminal-symbol}
-@end example
-
-@noindent
-and it is written after the components of the rule. Its effect is to
-assign the rule the precedence of @var{terminal-symbol}, overriding
-the precedence that would be deduced for it in the ordinary way. The
-altered rule precedence then affects how conflicts involving that rule
-are resolved (@pxref{Precedence, ,Operator Precedence}).
-
-Here is how @code{%prec} solves the problem of unary minus. First, declare
-a precedence for a fictitious terminal symbol named @code{UMINUS}. There
-are no tokens of this type, but the symbol serves to stand for its
-precedence:
-
-@example
-@dots{}
-%left '+' '-'
-%left '*'
-%left UMINUS
-@end example
-
-Now the precedence of @code{UMINUS} can be used in specific rules:
-
-@example
-@group
-exp: @dots{}
- | exp '-' exp
- @dots{}
- | '-' exp %prec UMINUS
-@end group
-@end example
-
-@ifset defaultprec
-If you forget to append @code{%prec UMINUS} to the rule for unary
-minus, Bison silently assumes that minus has its usual precedence.
-This kind of problem can be tricky to debug, since one typically
-discovers the mistake only by testing the code.
-
-The @code{%no-default-prec;} declaration makes it easier to discover
-this kind of problem systematically. It causes rules that lack a
-@code{%prec} modifier to have no precedence, even if the last terminal
-symbol mentioned in their components has a declared precedence.
-
-If @code{%no-default-prec;} is in effect, you must specify @code{%prec}
-for all rules that participate in precedence conflict resolution.
-Then you will see any shift/reduce conflict until you tell Bison how
-to resolve it, either by changing your grammar or by adding an
-explicit precedence. This will probably add declarations to the
-grammar, but it helps to protect against incorrect rule precedences.
-
-The effect of @code{%no-default-prec;} can be reversed by giving
-@code{%default-prec;}, which is the default.

-@node Parser States
-@section Parser States
-@cindex finite-state machine
-@cindex parser state
-@cindex state (of parser)
-
-The function @code{yyparse} is implemented using a finite-state machine.
-The values pushed on the parser stack are not simply token type codes; they
-represent the entire sequence of terminal and nonterminal symbols at or
-near the top of the stack. The current state collects all the information
-about previous input which is relevant to deciding what to do next.
-
-Each time a look-ahead token is read, the current parser state together
-with the type of look-ahead token are looked up in a table. This table
-entry can say, ``Shift the look-ahead token.'' In this case, it also
-specifies the new parser state, which is pushed onto the top of the
-parser stack. Or it can say, ``Reduce using rule number @var{n}.''
-This means that a certain number of tokens or groupings are taken off
-the top of the stack, and replaced by one grouping. In other words,
-that number of states are popped from the stack, and one new state is
-pushed.
-
-There is one other alternative: the table can say that the look-ahead token
-is erroneous in the current state. This causes error processing to begin
-(@pxref{Error Recovery}).
-
-@node Reduce/Reduce
-@section Reduce/Reduce Conflicts
-@cindex reduce/reduce conflict
-@cindex conflicts, reduce/reduce
-
-A reduce/reduce conflict occurs if there are two or more rules that apply
-to the same sequence of input. This usually indicates a serious error
-in the grammar.
-
-For example, here is an erroneous attempt to define a sequence
-of zero or more @code{word} groupings.
-
-@example
-sequence: /* empty */
- @{ printf ("empty sequence\n"); @}
- | maybeword
- | sequence word
- @{ printf ("added word %s\n", $2); @}
- ;
-
-maybeword: /* empty */
- @{ printf ("empty maybeword\n"); @}
- | word
- @{ printf ("single word %s\n", $1); @}
- ;
-@end example
-
-@noindent
-The error is an ambiguity: there is more than one way to parse a single
-@code{word} into a @code{sequence}. It could be reduced to a
-@code{maybeword} and then into a @code{sequence} via the second rule.
-Alternatively, nothing-at-all could be reduced into a @code{sequence}
-via the first rule, and this could be combined with the @code{word}
-using the third rule for @code{sequence}.
-
-There is also more than one way to reduce nothing-at-all into a
-@code{sequence}. This can be done directly via the first rule,
-or indirectly via @code{maybeword} and then the second rule.
-
-You might think that this is a distinction without a difference, because it
-does not change whether any particular input is valid or not. But it does
-affect which actions are run. One parsing order runs the second rule's
-action; the other runs the first rule's action and the third rule's action.
-In this example, the output of the program changes.
-
-Bison resolves a reduce/reduce conflict by choosing to use the rule that
-appears first in the grammar, but it is very risky to rely on this. Every
-reduce/reduce conflict must be studied and usually eliminated. Here is the
-proper way to define @code{sequence}:
-
-@example
-sequence: /* empty */
- @{ printf ("empty sequence\n"); @}
- | sequence word
- @{ printf ("added word %s\n", $2); @}
- ;
-@end example
-
-Here is another common error that yields a reduce/reduce conflict:
-
-@example
-sequence: /* empty */
- | sequence words
- | sequence redirects
- ;
-
-words: /* empty */
- | words word
- ;
-
-redirects:/* empty */
- | redirects redirect
- ;
-@end example
-
-@noindent
-The intention here is to define a sequence which can contain either
-@code{word} or @code{redirect} groupings. The individual definitions of
-@code{sequence}, @code{words} and @code{redirects} are error-free, but the
-three together make a subtle ambiguity: even an empty input can be parsed
-in infinitely many ways!
-
-Consider: nothing-at-all could be a @code{words}. Or it could be two
-@code{words} in a row, or three, or any number. It could equally well be a
-@code{redirects}, or two, or any number. Or it could be a @code{words}
-followed by three @code{redirects} and another @code{words}. And so on.
-
-Here are two ways to correct these rules. First, to make it a single level
-of sequence:
-
-@example
-sequence: /* empty */
- | sequence word
- | sequence redirect
- ;
-@end example
-
-Second, to prevent either a @code{words} or a @code{redirects}
-from being empty:
-
-@example
-sequence: /* empty */
- | sequence words
- | sequence redirects
- ;
-
-words: word
- | words word
- ;
-
-redirects:redirect
- | redirects redirect
- ;

-@node Mystery Conflicts
-@section Mysterious Reduce/Reduce Conflicts
-
-Sometimes reduce/reduce conflicts can occur that don't look warranted.
-Here is an example:
-
-@example
-@group
-%token ID
-
-%%
-def: param_spec return_spec ','
- ;
-param_spec:
- type
- | name_list ':' type
- ;
-@end group
-@group
-return_spec:

- | name ':' type
- ;

-type: ID
- ;
-@end group
-@group
-name: ID
- ;
-name_list:
- name
- | name ',' name_list
- ;
-@end group
-@end example
-
-It would seem that this grammar can be parsed with only a single token
-of look-ahead: when a @code{param_spec} is being read, an @code{ID} is
-a @code{name} if a comma or colon follows, or a @code{type} if another
-@code{ID} follows. In other words, this grammar is @acronym{LR}(1).
-
-@cindex @acronym{LR}(1)
-@cindex @acronym{LALR}(1)
-However, Bison, like most parser generators, cannot actually handle all
-@acronym{LR}(1) grammars. In this grammar, two contexts, that after
-an @code{ID}
-at the beginning of a @code{param_spec} and likewise at the beginning of
-a @code{return_spec}, are similar enough that Bison assumes they are the
-same. They appear similar because the same set of rules would be
-active---the rule for reducing to a @code{name} and that for reducing to
-a @code{type}. Bison is unable to determine at that stage of processing
-that the rules would require different look-ahead tokens in the two
-contexts, so it makes a single parser state for them both. Combining
-the two contexts causes a conflict later. In parser terminology, this
-occurrence means that the grammar is not @acronym{LALR}(1).
-
-In general, it is better to fix deficiencies than to document them. But
-this particular deficiency is intrinsically hard to fix; parser
-generators that can handle @acronym{LR}(1) grammars are hard to write
-and tend to
-produce parsers that are very large. In practice, Bison is more useful
-as it is now.
-
-When the problem arises, you can often fix it by identifying the two
-parser states that are being confused, and adding something to make them
-look distinct. In the above example, adding one rule to
-@code{return_spec} as follows makes the problem go away:
-
-@example
-@group
-%token BOGUS
-@dots{}
-%%
-@dots{}
-return_spec:
- type
- | name ':' type
- /* This rule is never used. */
- | ID BOGUS
- ;
-@end group
-@end example
-
-This corrects the problem because it introduces the possibility of an
-additional active rule in the context after the @code{ID} at the beginning of
-@code{return_spec}. This rule is not active in the corresponding context
-in a @code{param_spec}, so the two contexts receive distinct parser states.
-As long as the token @code{BOGUS} is never generated by @code{yylex},
-the added rule cannot alter the way actual input is parsed.
-
-In this particular example, there is another way to solve the problem:
-rewrite the rule for @code{return_spec} to use @code{ID} directly
-instead of via @code{name}. This also causes the two confusing
-contexts to have different sets of active rules, because the one for
-@code{return_spec} activates the altered rule for @code{return_spec}
-rather than the one for @code{name}.
-
-@example
-param_spec:
- type
- | name_list ':' type
- ;
-return_spec:
- type
- | ID ':' type
- ;

-@cindex ambiguous grammars
-@cindex nondeterministic parsing
-
-Bison produces @emph{deterministic} parsers that choose uniquely
-when to reduce and which reduction to apply
-based on a summary of the preceding input and on one extra token of look-ahead.
-As a result, normal Bison handles a proper subset of the family of
-context-free languages.
-Ambiguous grammars, since they have strings with more than one possible
-sequence of reductions cannot have deterministic parsers in this sense.
-The same is true of languages that require more than one symbol of
-look-ahead, since the parser lacks the information necessary to make a
-decision at the point it must be made in a shift-reduce parser.
-Finally, as previously mentioned (@pxref{Mystery Conflicts}),
-there are languages where Bison's particular choice of how to
-summarize the input seen so far loses necessary information.
-
-When you use the @samp{%glr-parser} declaration in your grammar file,
-Bison generates a parser that uses a different algorithm, called
-Generalized @acronym{LR} (or @acronym{GLR}). A Bison @acronym{GLR}
-parser uses the same basic
-algorithm for parsing as an ordinary Bison parser, but behaves
-differently in cases where there is a shift-reduce conflict that has not
-been resolved by precedence rules (@pxref{Precedence}) or a
-reduce-reduce conflict. When a @acronym{GLR} parser encounters such a
-situation, it
-effectively @emph{splits} into a several parsers, one for each possible
-shift or reduction. These parsers then proceed as usual, consuming
-tokens in lock-step. Some of the stacks may encounter other conflicts
-and split further, with the result that instead of a sequence of states,
-a Bison @acronym{GLR} parsing stack is what is in effect a tree of states.
-
-In effect, each stack represents a guess as to what the proper parse
-is. Additional input may indicate that a guess was wrong, in which case
-the appropriate stack silently disappears. Otherwise, the semantics
-actions generated in each stack are saved, rather than being executed
-immediately. When a stack disappears, its saved semantic actions never
-get executed. When a reduction causes two stacks to become equivalent,
-their sets of semantic actions are both saved with the state that
-results from the reduction. We say that two stacks are equivalent
-when they both represent the same sequence of states,
-and each pair of corresponding states represents a
-grammar symbol that produces the same segment of the input token
-stream.
-
-Whenever the parser makes a transition from having multiple
-states to having one, it reverts to the normal @acronym{LALR}(1) parsing
-algorithm, after resolving and executing the saved-up actions.
-At this transition, some of the states on the stack will have semantic
-values that are sets (actually multisets) of possible actions. The
-parser tries to pick one of the actions by first finding one whose rule
-has the highest dynamic precedence, as set by the @samp{%dprec}
-declaration. Otherwise, if the alternative actions are not ordered by
-precedence, but there the same merging function is declared for both
-rules by the @samp{%merge} declaration,
-Bison resolves and evaluates both and then calls the merge function on
-the result. Otherwise, it reports an ambiguity.
-
-It is possible to use a data structure for the @acronym{GLR} parsing tree that
-permits the processing of any @acronym{LALR}(1) grammar in linear time (in the
-size of the input), any unambiguous (not necessarily
-@acronym{LALR}(1)) grammar in
-quadratic worst-case time, and any general (possibly ambiguous)
-context-free grammar in cubic worst-case time. However, Bison currently
-uses a simpler data structure that requires time proportional to the
-length of the input times the maximum number of stacks required for any
-prefix of the input. Thus, really ambiguous or nondeterministic
-grammars can require exponential time and space to process. Such badly
-behaving examples, however, are not generally of practical interest.
-Usually, nondeterminism in a grammar is local---the parser is ``in
-doubt'' only for a few tokens at a time. Therefore, the current data
-structure should generally be adequate. On @acronym{LALR}(1) portions of a
-grammar, in particular, it is only slightly slower than with the default
-Bison parser.

-@cindex memory exhaustion
-@cindex memory management
-@cindex stack overflow
-@cindex parser stack overflow
-@cindex overflow of parser stack
-
-The Bison parser stack can run out of memory if too many tokens are shifted and
-not reduced. When this happens, the parser function @code{yyparse}
-calls @code{yyerror} and then returns 2.
-
-Because Bison parsers have growing stacks, hitting the upper limit
-usually results from using a right recursion instead of a left
-recursion, @xref{Recursion, ,Recursive Rules}.
-
-@vindex YYMAXDEPTH
-By defining the macro @code{YYMAXDEPTH}, you can control how deep the
-parser stack can become before memory is exhausted. Define the
-macro with a value that is an integer. This value is the maximum number
-of tokens that can be shifted (and not reduced) before overflow.
-
-The stack space allowed is not necessarily allocated. If you specify a
-large value for @code{YYMAXDEPTH}, the parser normally allocates a small
-stack at first, and then makes it bigger by stages as needed. This
-increasing allocation happens automatically and silently. Therefore,
-you do not need to make @code{YYMAXDEPTH} painfully small merely to save
-space for ordinary inputs that do not need much stack.
-
-However, do not allow @code{YYMAXDEPTH} to be a value so large that
-arithmetic overflow could occur when calculating the size of the stack
-space. Also, do not allow @code{YYMAXDEPTH} to be less than
-@code{YYINITDEPTH}.
-
-@cindex default stack limit
-The default value of @code{YYMAXDEPTH}, if you do not define it, is
-10000.
-
-@vindex YYINITDEPTH
-You can control how much stack is allocated initially by defining the
-macro @code{YYINITDEPTH} to a positive integer. For the C
-@acronym{LALR}(1) parser, this value must be a compile-time constant
-unless you are assuming C99 or some other target language or compiler
-that allows variable-length arrays. The default is 200.
-
-Do not allow @code{YYINITDEPTH} to be greater than @code{YYMAXDEPTH}.
-
-@c FIXME: C++ output.
-Because of semantical differences between C and C++, the

-@node Error Recovery
-@chapter Error Recovery
-@cindex error recovery
-@cindex recovery from errors
-
-It is not usually acceptable to have a program terminate on a syntax
-error. For example, a compiler should recover sufficiently to parse the
-rest of the input file and check it for errors; a calculator should accept
-another expression.
-
-In a simple interactive command parser where each input is one line, it may
-be sufficient to allow @code{yyparse} to return 1 on error and have the
-caller ignore the rest of the input line when that happens (and then call
-@code{yyparse} again). But this is inadequate for a compiler, because it
-forgets all the syntactic context leading up to the error. A syntax error
-deep within a function in the compiler input should not cause the compiler
-to treat the following line like the beginning of a source file.
-
-@findex error
-You can define how to recover from a syntax error by writing rules to
-recognize the special token @code{error}. This is a terminal symbol that
-is always defined (you need not declare it) and reserved for error
-handling. The Bison parser generates an @code{error} token whenever a
-syntax error happens; if you have provided a rule to recognize this token
-in the current context, the parse can continue.
-
-For example:
-
-@example
-stmnts: /* empty string */
- | stmnts '\n'
- | stmnts exp '\n'
- | stmnts error '\n'
-@end example
-
-The fourth rule in this example says that an error followed by a newline
-makes a valid addition to any @code{stmnts}.
-
-What happens if a syntax error occurs in the middle of an @code{exp}? The
-error recovery rule, interpreted strictly, applies to the precise sequence
-of a @code{stmnts}, an @code{error} and a newline. If an error occurs in
-the middle of an @code{exp}, there will probably be some additional tokens
-and subexpressions on the stack after the last @code{stmnts}, and there
-will be tokens to read before the next newline. So the rule is not
-applicable in the ordinary way.
-
-But Bison can force the situation to fit the rule, by discarding part of
-the semantic context and part of the input. First it discards states
-and objects from the stack until it gets back to a state in which the
-@code{error} token is acceptable. (This means that the subexpressions
-already parsed are discarded, back to the last complete @code{stmnts}.)
-At this point the @code{error} token can be shifted. Then, if the old
-look-ahead token is not acceptable to be shifted next, the parser reads
-tokens and discards them until it finds a token which is acceptable. In
-this example, Bison reads and discards input until the next newline so
-that the fourth rule can apply. Note that discarded symbols are
-possible sources of memory leaks, see @ref{Destructor Decl, , Freeing
-Discarded Symbols}, for a means to reclaim this memory.
-
-The choice of error rules in the grammar is a choice of strategies for
-error recovery. A simple and useful strategy is simply to skip the rest of
-the current input line or current statement if an error is detected:
-
-@example
-stmnt: error ';' /* On error, skip until ';' is read. */
-@end example
-
-It is also useful to recover to the matching close-delimiter of an
-opening-delimiter that has already been parsed. Otherwise the
-close-delimiter will probably appear to be unmatched, and generate another,
-spurious error message:
-
-@example
-primary: '(' expr ')'
- | '(' error ')'
- @dots{}
- ;
-@end example
-
-Error recovery strategies are necessarily guesses. When they guess wrong,
-one syntax error often leads to another. In the above example, the error
-recovery rule guesses that an error is due to bad input within one
-@code{stmnt}. Suppose that instead a spurious semicolon is inserted in the
-middle of a valid @code{stmnt}. After the error recovery rule recovers
-from the first error, another syntax error will be found straightaway,
-since the text following the spurious semicolon is also an invalid
-@code{stmnt}.
-
-To prevent an outpouring of error messages, the parser will output no error
-message for another syntax error that happens shortly after the first; only
-after three consecutive input tokens have been successfully shifted will
-error messages resume.
-
-Note that rules which accept the @code{error} token may have actions, just
-as any other rules can.
-
-@findex yyerrok
-You can make error messages resume immediately by using the macro
-@code{yyerrok} in an action. If you do this in the error rule's action, no
-error messages will be suppressed. This macro requires no arguments;
-@samp{yyerrok;} is a valid C statement.
-
-@findex yyclearin
-The previous look-ahead token is reanalyzed immediately after an error. If
-this is unacceptable, then the macro @code{yyclearin} may be used to clear
-this token. Write the statement @samp{yyclearin;} in the error rule's
-action.
-@xref{Action Features, ,Special Features for Use in Actions}.
-
-For example, suppose that on a syntax error, an error handling routine is
-called that advances the input stream to some point where parsing should
-once again commence. The next symbol returned by the lexical scanner is
-probably correct. The previous look-ahead token ought to be discarded
-with @samp{yyclearin;}.
-
-@vindex YYRECOVERING
-The expression @code{YYRECOVERING ()} yields 1 when the parser
-is recovering from a syntax error, and 0 otherwise.
-Syntax error diagnostics are suppressed while recovering from a syntax
-error.

-@node Context Dependency
-@chapter Handling Context Dependencies
-
-The Bison paradigm is to parse tokens first, then group them into larger
-syntactic units. In many languages, the meaning of a token is affected by
-its context. Although this violates the Bison paradigm, certain techniques
-(known as @dfn{kludges}) may enable you to write Bison parsers for such
-languages.
-
-@menu
-* Semantic Tokens:: Token parsing can depend on the semantic context.
-* Lexical Tie-ins:: Token parsing can depend on the syntactic context.
-* Tie-in Recovery:: Lexical tie-ins have implications for how
- error recovery rules must be written.
-@end menu
-
-(Actually, ``kludge'' means any technique that gets its job done but is
-neither clean nor robust.)
-
-@node Semantic Tokens
-@section Semantic Info in Token Types
-
-The C language has a context dependency: the way an identifier is used
-depends on what its current meaning is. For example, consider this:
-
-@example
-foo (x);
-@end example
-
-This looks like a function call statement, but if @code{foo} is a typedef
-name, then this is actually a declaration of @code{x}. How can a Bison
-parser for C decide how to parse this input?
-
-The method used in @acronym{GNU} C is to have two different token types,
-@code{IDENTIFIER} and @code{TYPENAME}. When @code{yylex} finds an
-identifier, it looks up the current declaration of the identifier in order
-to decide which token type to return: @code{TYPENAME} if the identifier is
-declared as a typedef, @code{IDENTIFIER} otherwise.
-
-The grammar rules can then express the context dependency by the choice of
-token type to recognize. @code{IDENTIFIER} is accepted as an expression,
-but @code{TYPENAME} is not. @code{TYPENAME} can start a declaration, but
-@code{IDENTIFIER} cannot. In contexts where the meaning of the identifier
-is @emph{not} significant, such as in declarations that can shadow a
-typedef name, either @code{TYPENAME} or @code{IDENTIFIER} is
-accepted---there is one rule for each of the two token types.
-
-This technique is simple to use if the decision of which kinds of
-identifiers to allow is made at a place close to where the identifier is
-parsed. But in C this is not always so: C allows a declaration to
-redeclare a typedef name provided an explicit type has been specified
-earlier:
-
-@example
-typedef int foo, bar;
-int baz (void)
-@{
- static bar (bar); /* @r{redeclare @code{bar} as static variable} */
- extern foo foo (foo); /* @r{redeclare @code{foo} as function} */
- return foo (bar);
-@}
-@end example
-
-Unfortunately, the name being declared is separated from the declaration
-construct itself by a complicated syntactic structure---the ``declarator''.
-
-As a result, part of the Bison parser for C needs to be duplicated, with
-all the nonterminal names changed: once for parsing a declaration in
-which a typedef name can be redefined, and once for parsing a
-declaration in which that can't be done. Here is a part of the
-duplication, with actions omitted for brevity:
-
-@example
-initdcl:
- declarator maybeasm '='
- init
- | declarator maybeasm
- ;
-
-notype_initdcl:
- notype_declarator maybeasm '='
- init
- | notype_declarator maybeasm
- ;
-@end example
-
-@noindent
-Here @code{initdcl} can redeclare a typedef name, but @code{notype_initdcl}
-cannot. The distinction between @code{declarator} and
-@code{notype_declarator} is the same sort of thing.
-
-There is some similarity between this technique and a lexical tie-in
-(described next), in that information which alters the lexical analysis is
-changed during parsing by other parts of the program. The difference is
-here the information is global, and is used for other purposes in the
-program. A true lexical tie-in has a special-purpose flag controlled by
-the syntactic context.
-
-@node Lexical Tie-ins
-@section Lexical Tie-ins
-@cindex lexical tie-in
-
-One way to handle context-dependency is the @dfn{lexical tie-in}: a flag
-which is set by Bison actions, whose purpose is to alter the way tokens are
-parsed.
-
-For example, suppose we have a language vaguely like C, but with a special
-construct @samp{hex (@var{hex-expr})}. After the keyword @code{hex} comes
-an expression in parentheses in which all integers are hexadecimal. In
-particular, the token @samp{a1b} must be treated as an integer rather than
-as an identifier if it appears in that context. Here is how you can do it:
-
-@example
-@group
-%@{
- int hexflag;
- int yylex (void);
- void yyerror (char const *);
-%@}
-%%
-@dots{}
-@end group
-@group
-expr: IDENTIFIER
- | constant
- | HEX '('
- @{ hexflag = 1; @}
- expr ')'
- @{ hexflag = 0;
- $$ = $4; @}
- | expr '+' expr
- @{ $$ = make_sum ($1, $3); @}
- @dots{}
- ;
-@end group
-
-@group
-constant:
- INTEGER
- | STRING
- ;
-@end group
-@end example
-
-@noindent
-Here we assume that @code{yylex} looks at the value of @code{hexflag}; when
-it is nonzero, all integers are parsed in hexadecimal, and tokens starting
-with letters are parsed as integers if possible.
-
-The declaration of @code{hexflag} shown in the prologue of the parser file
-is needed to make it accessible to the actions (@pxref{Prologue, ,The Prologue}).
-You must also write the code in @code{yylex} to obey the flag.
-
-@node Tie-in Recovery
-@section Lexical Tie-ins and Error Recovery
-
-Lexical tie-ins make strict demands on any error recovery rules you have.
-@xref{Error Recovery}.
-
-The reason for this is that the purpose of an error recovery rule is to
-abort the parsing of one construct and resume in some larger construct.
-For example, in C-like languages, a typical error recovery rule is to skip
-tokens until the next semicolon, and then start a new statement, like this:
-
-@example
-stmt: expr ';'
- | IF '(' expr ')' stmt @{ @dots{} @}
- @dots{}
- error ';'
- @{ hexflag = 0; @}
- ;
-@end example
-
-If there is a syntax error in the middle of a @samp{hex (@var{expr})}
-construct, this error rule will apply, and then the action for the
-completed @samp{hex (@var{expr})} will never run. So @code{hexflag} would
-remain set for the entire rest of the input, or until the next @code{hex}
-keyword, causing identifiers to be misinterpreted as integers.
-
-To avoid this problem the error recovery rule itself clears @code{hexflag}.
-
-There may also be an error recovery rule that works within expressions.
-For example, there could be a rule which applies within parentheses
-and skips to the close-parenthesis:
-
-@example
-@group
-expr: @dots{}
- | '(' expr ')'
- @{ $$ = $2; @}
- | '(' error ')'
- @dots{}
-@end group
-@end example
-
-If this rule acts within the @code{hex} construct, it is not going to abort
-that construct (since it applies to an inner level of parentheses within
-the construct). Therefore, it should not clear the flag: the rest of
-the @code{hex} construct should be parsed with the flag still in effect.
-
-What if there is an error recovery rule which might abort out of the
-@code{hex} construct or might not, depending on circumstances? There is no
-way you can write the action to determine whether a @code{hex} construct is
-being aborted or not. So if you are using a lexical tie-in, you had better
-make sure your error recovery rules are not of this kind. Each rule must
-be such that you can be sure that it always will, or always won't, have to
-clear the flag.

-@chapter Debugging Your Parser
-
-Developing a parser can be a challenge, especially if you don't
-understand the algorithm (@pxref{Algorithm, ,The Bison Parser
-Algorithm}). Even so, sometimes a detailed description of the automaton
-can help (@pxref{Understanding, , Understanding Your Parser}), or
-tracing the execution of the parser can give some insight on why it
-behaves improperly (@pxref{Tracing, , Tracing Your Parser}).

-@node Understanding
-@section Understanding Your Parser
-
-As documented elsewhere (@pxref{Algorithm, ,The Bison Parser Algorithm})
-Bison parsers are @dfn{shift/reduce automata}. In some cases (much more
-frequent than one would hope), looking at this automaton is required to
-tune or simply fix a parser. Bison provides two different
-representation of it, either textually or graphically (as a @acronym{VCG}
-file).
-
-The textual file is generated when the options @option{--report} or
-@option{--verbose} are specified, see @xref{Invocation, , Invoking
-Bison}. Its name is made by removing @samp{.tab.c} or @samp{.c} from
-the parser output file name, and adding @samp{.output} instead.
-Therefore, if the input file is @file{foo.y}, then the parser file is
-called @file{foo.tab.c} by default. As a consequence, the verbose
-output file is called @file{foo.output}.
-
-The following grammar file, @file{calc.y}, will be used in the sequel:
-
-@example
-%token NUM STR
-%left '+' '-'
-%left '*'
-%%
-exp: exp '+' exp
- | exp '-' exp
- | exp '*' exp
- | exp '/' exp
- | NUM
- ;
-useless: STR;
-%%
-@end example
-
-@command{bison} reports:
-
-@example
-calc.y: warning: 1 useless nonterminal and 1 useless rule
-calc.y:11.1-7: warning: useless nonterminal: useless
-calc.y:11.10-12: warning: useless rule: useless: STR
-calc.y: conflicts: 7 shift/reduce
-@end example
-
-When given @option{--report=state}, in addition to @file{calc.tab.c}, it
-creates a file @file{calc.output} with contents detailed below. The
-order of the output and the exact presentation might vary, but the
-interpretation is the same.
-
-The first section includes details on conflicts that were solved thanks
-to precedence and/or associativity:
-
-@example
-Conflict in state 8 between rule 2 and token '+' resolved as reduce.
-Conflict in state 8 between rule 2 and token '-' resolved as reduce.
-Conflict in state 8 between rule 2 and token '*' resolved as shift.
-@exdent @dots{}
-@end example
-
-@noindent
-The next section lists states that still have conflicts.
-
-@example
-State 8 conflicts: 1 shift/reduce
-State 9 conflicts: 1 shift/reduce
-State 10 conflicts: 1 shift/reduce
-State 11 conflicts: 4 shift/reduce
-@end example
-
-@noindent
-@cindex token, useless
-@cindex useless token
-@cindex nonterminal, useless
-@cindex useless nonterminal
-@cindex rule, useless
-@cindex useless rule
-The next section reports useless tokens, nonterminal and rules. Useless
-nonterminals and rules are removed in order to produce a smaller parser,
-but useless tokens are preserved, since they might be used by the
-scanner (note the difference between ``useless'' and ``not used''
-below):
-
-@example
-Useless nonterminals:
- useless
-
-Terminals which are not used:
- STR
-
-Useless rules:
-#6 useless: STR;
-@end example
-
-@noindent
-The next section reproduces the exact grammar that Bison used:
-
-@example
-Grammar
-
- Number, Line, Rule
- 0 5 $accept -> exp $end
- 1 5 exp -> exp '+' exp
- 2 6 exp -> exp '-' exp
- 3 7 exp -> exp '*' exp
- 4 8 exp -> exp '/' exp
- 5 9 exp -> NUM
-@end example
-
-@noindent
-and reports the uses of the symbols:
-
-@example
-Terminals, with rules where they appear
-
-$end (0) 0
-'*' (42) 3
-'+' (43) 1
-'-' (45) 2
-'/' (47) 4
-error (256)
-NUM (258) 5
-
-Nonterminals, with rules where they appear
-
-$accept (8)
- on left: 0
-exp (9)
- on left: 1 2 3 4 5, on right: 0 1 2 3 4
-@end example
-
-@noindent
-@cindex item
-@cindex pointed rule
-@cindex rule, pointed
-Bison then proceeds onto the automaton itself, describing each state
-with it set of @dfn{items}, also known as @dfn{pointed rules}. Each
-item is a production rule together with a point (marked by @samp{.})
-that the input cursor.
-
-@example
-state 0
-
- $accept -> . exp $ (rule 0)
-
- NUM shift, and go to state 1
-
- exp go to state 2
-@end example
-
-This reads as follows: ``state 0 corresponds to being at the very
-beginning of the parsing, in the initial rule, right before the start
-symbol (here, @code{exp}). When the parser returns to this state right
-after having reduced a rule that produced an @code{exp}, the control
-flow jumps to state 2. If there is no such transition on a nonterminal
-symbol, and the look-ahead is a @code{NUM}, then this token is shifted on
-the parse stack, and the control flow jumps to state 1. Any other
-look-ahead triggers a syntax error.''
-
-@cindex core, item set
-@cindex item set core
-@cindex kernel, item set
-@cindex item set core
-Even though the only active rule in state 0 seems to be rule 0, the
-report lists @code{NUM} as a look-ahead token because @code{NUM} can be
-at the beginning of any rule deriving an @code{exp}. By default Bison
-reports the so-called @dfn{core} or @dfn{kernel} of the item set, but if
-you want to see more detail you can invoke @command{bison} with
-@option{--report=itemset} to list all the items, include those that can
-be derived:
-
-@example
-state 0
-
- $accept -> . exp $ (rule 0)
- exp -> . exp '+' exp (rule 1)
- exp -> . exp '-' exp (rule 2)
- exp -> . exp '*' exp (rule 3)
- exp -> . exp '/' exp (rule 4)
- exp -> . NUM (rule 5)
-
- NUM shift, and go to state 1
-
- exp go to state 2
-@end example
-
-@noindent
-In the state 1...
-
-@example
-state 1
-
- exp -> NUM . (rule 5)
-
- $default reduce using rule 5 (exp)
-@end example
-
-@noindent
-the rule 5, @samp{exp: NUM;}, is completed. Whatever the look-ahead token
-(@samp{$default}), the parser will reduce it. If it was coming from
-state 0, then, after this reduction it will return to state 0, and will
-jump to state 2 (@samp{exp: go to state 2}).
-
-@example
-state 2
-
- $accept -> exp . $ (rule 0)
- exp -> exp . '+' exp (rule 1)
- exp -> exp . '-' exp (rule 2)
- exp -> exp . '*' exp (rule 3)
- exp -> exp . '/' exp (rule 4)
-
- $ shift, and go to state 3
- '+' shift, and go to state 4
- '-' shift, and go to state 5
- '*' shift, and go to state 6
- '/' shift, and go to state 7
-@end example
-
-@noindent
-In state 2, the automaton can only shift a symbol. For instance,
-because of the item @samp{exp -> exp . '+' exp}, if the look-ahead if
-@samp{+}, it will be shifted on the parse stack, and the automaton
-control will jump to state 4, corresponding to the item @samp{exp -> exp
-'+' . exp}. Since there is no default action, any other token than
-those listed above will trigger a syntax error.
-
-The state 3 is named the @dfn{final state}, or the @dfn{accepting
-state}:
-
-@example
-state 3
-
- $accept -> exp $ . (rule 0)
-
- $default accept
-@end example
-
-@noindent
-the initial rule is completed (the start symbol and the end
-of input were read), the parsing exits successfully.
-
-The interpretation of states 4 to 7 is straightforward, and is left to
-the reader.
-
-@example
-state 4
-
- exp -> exp '+' . exp (rule 1)
-
- NUM shift, and go to state 1
-
- exp go to state 8
-
-state 5
-
- exp -> exp '-' . exp (rule 2)
-
- NUM shift, and go to state 1
-
- exp go to state 9
-
-state 6
-
- exp -> exp '*' . exp (rule 3)
-
- NUM shift, and go to state 1
-
- exp go to state 10
-
-state 7
-
- exp -> exp '/' . exp (rule 4)
-
- NUM shift, and go to state 1
-
- exp go to state 11
-@end example
-
-As was announced in beginning of the report, @samp{State 8 conflicts:
-1 shift/reduce}:
-
-@example
-state 8
-
- exp -> exp . '+' exp (rule 1)
- exp -> exp '+' exp . (rule 1)
- exp -> exp . '-' exp (rule 2)
- exp -> exp . '*' exp (rule 3)
- exp -> exp . '/' exp (rule 4)
-
- '*' shift, and go to state 6
- '/' shift, and go to state 7
-
- '/' [reduce using rule 1 (exp)]
- $default reduce using rule 1 (exp)
-@end example
-
-Indeed, there are two actions associated to the look-ahead @samp{/}:
-either shifting (and going to state 7), or reducing rule 1. The
-conflict means that either the grammar is ambiguous, or the parser lacks
-information to make the right decision. Indeed the grammar is
-ambiguous, as, since we did not specify the precedence of @samp{/}, the
-sentence @samp{NUM + NUM / NUM} can be parsed as @samp{NUM + (NUM /
-NUM)}, which corresponds to shifting @samp{/}, or as @samp{(NUM + NUM) /
-NUM}, which corresponds to reducing rule 1.
-
-Because in @acronym{LALR}(1) parsing a single decision can be made, Bison
-arbitrarily chose to disable the reduction, see @ref{Shift/Reduce, ,
-Shift/Reduce Conflicts}. Discarded actions are reported in between
-square brackets.
-
-Note that all the previous states had a single possible action: either
-shifting the next token and going to the corresponding state, or
-reducing a single rule. In the other cases, i.e., when shifting
-@emph{and} reducing is possible or when @emph{several} reductions are
-possible, the look-ahead is required to select the action. State 8 is
-one such state: if the look-ahead is @samp{*} or @samp{/} then the action
-is shifting, otherwise the action is reducing rule 1. In other words,
-the first two items, corresponding to rule 1, are not eligible when the
-look-ahead token is @samp{*}, since we specified that @samp{*} has higher
-precedence than @samp{+}. More generally, some items are eligible only
-with some set of possible look-ahead tokens. When run with
-@option{--report=look-ahead}, Bison specifies these look-ahead tokens:
-
-@example
-state 8
-
- exp -> exp . '+' exp [$, '+', '-', '/'] (rule 1)
- exp -> exp '+' exp . [$, '+', '-', '/'] (rule 1)
- exp -> exp . '-' exp (rule 2)
- exp -> exp . '*' exp (rule 3)
- exp -> exp . '/' exp (rule 4)
-
- '*' shift, and go to state 6
- '/' shift, and go to state 7
-
- '/' [reduce using rule 1 (exp)]
- $default reduce using rule 1 (exp)
-@end example
-
-The remaining states are similar:
-
-@example
-state 9
-
- exp -> exp . '+' exp (rule 1)
- exp -> exp . '-' exp (rule 2)
- exp -> exp '-' exp . (rule 2)
- exp -> exp . '*' exp (rule 3)
- exp -> exp . '/' exp (rule 4)
-
- '*' shift, and go to state 6
- '/' shift, and go to state 7
-
- '/' [reduce using rule 2 (exp)]
- $default reduce using rule 2 (exp)
-
-state 10
-
- exp -> exp . '+' exp (rule 1)
- exp -> exp . '-' exp (rule 2)
- exp -> exp . '*' exp (rule 3)
- exp -> exp '*' exp . (rule 3)
- exp -> exp . '/' exp (rule 4)
-
- '/' shift, and go to state 7
-
- '/' [reduce using rule 3 (exp)]
- $default reduce using rule 3 (exp)
-
-state 11
-
- exp -> exp . '+' exp (rule 1)
- exp -> exp . '-' exp (rule 2)
- exp -> exp . '*' exp (rule 3)
- exp -> exp . '/' exp (rule 4)
- exp -> exp '/' exp . (rule 4)
-
- '+' shift, and go to state 4
- '-' shift, and go to state 5
- '*' shift, and go to state 6
- '/' shift, and go to state 7
-
- '+' [reduce using rule 4 (exp)]
- '-' [reduce using rule 4 (exp)]
- '*' [reduce using rule 4 (exp)]
- '/' [reduce using rule 4 (exp)]
- $default reduce using rule 4 (exp)
-@end example
-
-@noindent
-Observe that state 11 contains conflicts not only due to the lack of
-precedence of @samp{/} with respect to @samp{+}, @samp{-}, and
-@samp{*}, but also because the
-associativity of @samp{/} is not specified.

-@cindex debugging
-@cindex tracing the parser
-
-If a Bison grammar compiles properly but doesn't do what you want when it
-runs, the @code{yydebug} parser-trace feature can help you figure out why.
-
-There are several means to enable compilation of trace facilities:
-
-@table @asis
-@item the macro @code{YYDEBUG}
-@findex YYDEBUG
-Define the macro @code{YYDEBUG} to a nonzero value when you compile the
-parser. This is compliant with @acronym{POSIX} Yacc. You could use
-@samp{-DYYDEBUG=1} as a compiler option or you could put @samp{#define
-YYDEBUG 1} in the prologue of the grammar file (@pxref{Prologue, , The
-Prologue}).
-
-@item the option @option{-t}, @option{--debug}
-Use the @samp{-t} option when you run Bison (@pxref{Invocation,
-,Invoking Bison}). This is @acronym{POSIX} compliant too.
-
-@item the directive @samp{%debug}
-@findex %debug
-Add the @code{%debug} directive (@pxref{Decl Summary, ,Bison
-Declaration Summary}). This is a Bison extension, which will prove
-useful when Bison will output parsers for languages that don't use a
-preprocessor. Unless @acronym{POSIX} and Yacc portability matter to
-you, this is
-the preferred solution.
-@end table
-
-We suggest that you always enable the debug option so that debugging is
-always possible.
-
-The trace facility outputs messages with macro calls of the form
-@code{YYFPRINTF (stderr, @var{format}, @var{args})} where
-@var{format} and @var{args} are the usual @code{printf} format and
-arguments. If you define @code{YYDEBUG} to a nonzero value but do not
-define @code{YYFPRINTF}, @code{<stdio.h>} is automatically included
-and @code{YYPRINTF} is defined to @code{fprintf}.
-
-Once you have compiled the program with trace facilities, the way to
-request a trace is to store a nonzero value in the variable @code{yydebug}.
-You can do this by making the C code do it (in @code{main}, perhaps), or
-you can alter the value with a C debugger.
-
-Each step taken by the parser when @code{yydebug} is nonzero produces a
-line or two of trace information, written on @code{stderr}. The trace
-messages tell you these things:
-
-@itemize @bullet
-@item
-Each time the parser calls @code{yylex}, what kind of token was read.
-
-@item
-Each time a token is shifted, the depth and complete contents of the
-state stack (@pxref{Parser States}).
-
-@item
-Each time a rule is reduced, which rule it is, and the complete contents
-of the state stack afterward.
-@end itemize
-
-To make sense of this information, it helps to refer to the listing file
-produced by the Bison @samp{-v} option (@pxref{Invocation, ,Invoking
-Bison}). This file shows the meaning of each state in terms of
-positions in various rules, and also what each state will do with each
-possible input token. As you read the successive trace messages, you
-can see that the parser is functioning according to its specification in
-the listing file. Eventually you will arrive at the place where
-something undesirable happens, and you will see which parts of the
-grammar are to blame.
-
-The parser file is a C program and you can use C debuggers on it, but it's
-not easy to interpret what it is doing. The parser function is a
-finite-state machine interpreter, and aside from the actions it executes
-the same code over and over. Only the values of variables show where in
-the grammar it is working.
-
-@findex YYPRINT
-The debugging information normally gives the token type of each token
-read, but not its semantic value. You can optionally define a macro
-named @code{YYPRINT} to provide a way to print the value. If you define
-@code{YYPRINT}, it should take three arguments. The parser will pass a
-standard I/O stream, the numeric code for the token type, and the token
-value (from @code{yylval}).
-
-Here is an example of @code{YYPRINT} suitable for the multi-function
-calculator (@pxref{Mfcalc Decl, ,Declarations for @code{mfcalc}}):
-
-@smallexample
-%@{
- static void print_token_value (FILE *, int, YYSTYPE);
- #define YYPRINT(file, type, value) print_token_value (file, type, value)
-%@}

-@{
- if (type == VAR)
- fprintf (file, "%s", value.tptr->name);
- else if (type == NUM)

-
-@node Invocation
-@chapter Invoking Bison
-@cindex invoking Bison
-@cindex Bison invocation
-@cindex options for invoking Bison
-
-The usual way to invoke Bison is as follows:
-
-@example
-bison @var{infile}
-@end example
-
-Here @var{infile} is the grammar file name, which usually ends in
-@samp{.y}. The parser file's name is made by replacing the @samp{.y}
-with @samp{.tab.c} and removing any leading directory. Thus, the
-@samp{bison foo.y} file name yields
-@file{foo.tab.c}, and the @samp{bison hack/foo.y} file name yields
-@file{foo.tab.c}. It's also possible, in case you are writing
-C++ code instead of C in your grammar file, to name it @file{foo.ypp}
-or @file{foo.y++}. Then, the output files will take an extension like
-the given one as input (respectively @file{foo.tab.cpp} and
-@file{foo.tab.c++}).
-This feature takes effect with all options that manipulate file names like
-@samp{-o} or @samp{-d}.
-
-For example :
-
-@example
-bison -d @var{infile.yxx}
-@end example
-@noindent
-will produce @file{infile.tab.cxx} and @file{infile.tab.hxx}, and
-
-@example
-bison -d -o @var{output.c++} @var{infile.y}
-@end example
-@noindent
-will produce @file{output.c++} and @file{outfile.h++}.
-
-For compatibility with @acronym{POSIX}, the standard Bison
-distribution also contains a shell script called @command{yacc} that
-invokes Bison with the @option{-y} option.

-@node Bison Options
-@section Bison Options
-
-Bison supports both traditional single-letter options and mnemonic long
-option names. Long option names are indicated with @samp{--} instead of
-@samp{-}. Abbreviations for option names are allowed as long as they
-are unique. When a long option takes an argument, like
-@samp{--file-prefix}, connect the option name and the argument with
-@samp{=}.
-
-Here is a list of options that can be used with Bison, alphabetized by
-short option. It is followed by a cross key alphabetized by long
-option.
-
-@c Please, keep this ordered as in `bison --help'.
-@noindent
-Operations modes:
-@table @option
-@item -h
-@itemx --help
-Print a summary of the command-line options to Bison and exit.
-
-@item -V
-@itemx --version
-Print the version number of Bison and exit.
-
-@item --print-localedir
-Print the name of the directory containing locale-dependent data.
-
-@item -y
-@itemx --yacc
-Act more like the traditional Yacc command. This can cause
-different diagnostics to be generated, and may change behavior in
-other minor ways. Most importantly, imitate Yacc's output
-file name conventions, so that the parser output file is called
-@file{y.tab.c}, and the other outputs are called @file{y.output} and
-@file{y.tab.h}. Thus, the following shell script can substitute
-for Yacc, and the Bison distribution contains such a script for
-compatibility with @acronym{POSIX}:
-
-@example
-#! /bin/sh
-bison -y "$@@"
-@end example
-
-The @option{-y}/@option{--yacc} option is intended for use with
-traditional Yacc grammars. If your grammar uses a Bison extension
-like @samp{%glr-parser}, Bison might not be Yacc-compatible even if
-this option is specified.

-

-Don't put any @code{#line} preprocessor commands in the parser file.
-Ordinarily Bison puts them in the parser file so that the C compiler

-@c - An env
-@c - A place to store error messages
-@c - A place for the result
-
-To support a pure interface with the parser (and the scanner) the
-technique of the ``parsing context'' is convenient: a structure
-containing all the data to exchange. Since, in addition to simply
-launch the parsing, there are several auxiliary tasks to execute (open
-the file for parsing, instantiate the parser etc.), we recommend
-transforming the simple parsing context structure into a fully blown
-@dfn{parsing driver} class.
-
-The declaration of this driver class, @file{calc++-driver.hh}, is as
-follows. The first part includes the CPP guard and imports the
-required standard library components, and the declaration of the parser
-class.
-
-@comment file: calc++-driver.hh
-@example
-#ifndef CALCXX_DRIVER_HH
-# define CALCXX_DRIVER_HH
-# include <string>
-# include <map>
-# include "calc++-parser.hh"
-@end example
-
-
-@noindent
-Then comes the declaration of the scanning function. Flex expects
-the signature of @code{yylex} to be defined in the macro
-@code{YY_DECL}, and the C++ parser expects it to be declared. We can
-factor both as follows.
-
-@comment file: calc++-driver.hh
-@example
-// Announce to Flex the prototype we want for lexing function, ...
-# define YY_DECL \
- yy::calcxx_parser::token_type \
- yylex (yy::calcxx_parser::semantic_type* yylval, \
- yy::calcxx_parser::location_type* yylloc, \
- calcxx_driver& driver)
-// ... and declare it for the parser's sake.
-YY_DECL;
-@end example
-
-@noindent
-The @code{calcxx_driver} class is then declared with its most obvious
-members.
-
-@comment file: calc++-driver.hh

-// Conducting the whole scanning and parsing of Calc++.
-class calcxx_driver
-@{
-public:
- calcxx_driver ();
- virtual ~calcxx_driver ();
-
- std::map<std::string, int> variables;
-
- int result;
-@end example
-
-@noindent
-To encapsulate the coordination with the Flex scanner, it is useful to
-have two members function to open and close the scanning phase.
-members.
-
-@comment file: calc++-driver.hh
-@example
- // Handling the scanner.
- void scan_begin ();
- void scan_end ();
- bool trace_scanning;
-@end example
-
-@noindent
-Similarly for the parser itself.
-
-@comment file: calc++-driver.hh
-@example
- // Handling the parser.
- void parse (const std::string& f);
- std::string file;
- bool trace_parsing;
-@end example
-
-@noindent
-To demonstrate pure handling of parse errors, instead of simply
-dumping them on the standard error output, we will pass them to the
-compiler driver using the following two member functions. Finally, we
-close the class declaration and CPP guard.
-
-@comment file: calc++-driver.hh
-@example
- // Error handling.
- void error (const yy::location& l, const std::string& m);
- void error (const std::string& m);
-@};
-#endif // ! CALCXX_DRIVER_HH
-@end example
-
-The implementation of the driver is straightforward. The @code{parse}
-member function deserves some attention. The @code{error} functions
-are simple stubs, they should actually register the located error
-messages and set error state.

-@subsection Calc++ Parser
-
-The parser definition file @file{calc++-parser.yy} starts by asking for
-the C++ LALR(1) skeleton, the creation of the parser header file, and
-specifies the name of the parser class. Because the C++ skeleton
-changed several times, it is safer to require the version you designed
-the grammar for.
-
-@comment file: calc++-parser.yy
-@example
-%skeleton "lalr1.cc" /* -*- C++ -*- */
-%require "2.1a"
-%defines
-%define "parser_class_name" "calcxx_parser"
-@end example
-
-@noindent
-Then come the declarations/inclusions needed to define the
-@code{%union}. Because the parser uses the parsing driver and
-reciprocally, both cannot include the header of the other. Because the
-driver's header needs detailed knowledge about the parser class (in
-particular its inner types), it is the parser's header which will simply
-use a forward declaration of the driver.
-
-@comment file: calc++-parser.yy
-@example
-%@{
-# include <string>
-class calcxx_driver;
-%@}
-@end example
-
-@noindent
-The driver is passed by reference to the parser and to the scanner.
-This provides a simple but effective pure interface, not relying on
-global variables.
-
-@comment file: calc++-parser.yy
-@example
-// The parsing context.
-%parse-param @{ calcxx_driver& driver @}
-%lex-param @{ calcxx_driver& driver @}
-@end example
-
-@noindent
-Then we request the location tracking feature, and initialize the
-first location's file name. Afterwards new locations are computed
-relatively to the previous locations: the file name will be
-automatically propagated.
-
-@comment file: calc++-parser.yy
-@example
-%locations
-%initial-action
-@{
- // Initialize the initial location.
- @@$.begin.filename = @@$.end.filename = &driver.file;
-@};
-@end example
-
-@noindent
-Use the two following directives to enable parser tracing and verbose
-error messages.
-
-@comment file: calc++-parser.yy
-@example
-%debug
-%error-verbose
-@end example
-
-@noindent
-Semantic values cannot use ``real'' objects, but only pointers to
-them.
-
-@comment file: calc++-parser.yy
-@example
-// Symbols.
-%union
-@{
- int ival;
- std::string *sval;
-@};
-@end example
-
-@noindent
-The code between @samp{%@{} and @samp{%@}} after the introduction of the
-@samp{%union} is output in the @file{*.cc} file; it needs detailed
-knowledge about the driver.
-
-@comment file: calc++-parser.yy
-@example
-%@{
-# include "calc++-driver.hh"
-%@}
-@end example
-
-
-@noindent
-The token numbered as 0 corresponds to end of file; the following line
-allows for nicer error messages referring to ``end of file'' instead
-of ``$end''. Similarly user friendly named are provided for each
-symbol. Note that the tokens names are prefixed by @code{TOKEN_} to
-avoid name clashes.
-
-@comment file: calc++-parser.yy
-@example
-%token END 0 "end of file"
-%token ASSIGN ":="
-%token <sval> IDENTIFIER "identifier"
-%token <ival> NUMBER "number"
-%type <ival> exp "expression"
-@end example
-
-@noindent
-To enable memory deallocation during error recovery, use
-@code{%destructor}.
-
-@c FIXME: Document %printer, and mention that it takes a braced-code operand.
-@comment file: calc++-parser.yy
-@example
-%printer @{ debug_stream () << *$$; @} "identifier"
-%destructor @{ delete $$; @} "identifier"
-
-%printer @{ debug_stream () << $$; @} "number" "expression"
-@end example
-
-@noindent
-The grammar itself is straightforward.
-
-@comment file: calc++-parser.yy
-@example
-%%
-%start unit;
-unit: assignments exp @{ driver.result = $2; @};
-
-assignments: assignments assignment @{@}
- | /* Nothing. */ @{@};
-
-assignment: "identifier" ":=" exp @{ driver.variables[*$1] = $3; @};
-
-%left '+' '-';
-%left '*' '/';
-exp: exp '+' exp @{ $$ = $1 + $3; @}
- | exp '-' exp @{ $$ = $1 - $3; @}
- | exp '*' exp @{ $$ = $1 * $3; @}
- | exp '/' exp @{ $$ = $1 / $3; @}
- | "identifier" @{ $$ = driver.variables[*$1]; @}
- | "number" @{ $$ = $1; @};
-%%
-@end example
-
-@noindent
-Finally the @code{error} member function registers the errors to the
-driver.
-
-@comment file: calc++-parser.yy
-@example
-void
-yy::calcxx_parser::error (const yy::calcxx_parser::location_type& l,

-@end example
-
-@noindent
-Because there is no @code{#include}-like feature we don't need
-@code{yywrap}, we don't need @code{unput} either, and we parse an
-actual file, this is not an interactive session with the user.
-Finally we enable the scanner tracing features.

-@example
-id [a-zA-Z][a-zA-Z_0-9]*
-int [0-9]+
-blank [ \t]
-@end example
-
-@noindent
-The following paragraph suffices to track locations accurately. Each
-time @code{yylex} is invoked, the begin position is moved onto the end
-position. Then when a pattern is matched, the end position is
-advanced of its width. In case it matched ends of lines, the end
-cursor is adjusted, and each time blanks are matched, the begin cursor
-is moved onto the end cursor to effectively ignore the blanks
-preceding tokens. Comments would be treated equally.
-
-@comment file: calc++-scanner.ll

-
-@noindent
-The rules are simple, just note the use of the driver to report errors.
-It is convenient to use a typedef to shorten
-@code{yy::calcxx_parser::token::identifier} into
-@code{token::identifier} for instance.
-

-

-message. What can I do?
-@end display
-
-This question is already addressed elsewhere, @xref{Recursion,
-,Recursive Rules}.
-
-@node How Can I Reset the Parser
-@section How Can I Reset the Parser
-
-The following phenomenon has several symptoms, resulting in the
-following typical questions:
-
-@display
-I invoke @code{yyparse} several times, and on correct input it works
-properly; but when a parse error is found, all the other calls fail
-too. How can I reset the error flag of @code{yyparse}?
-@end display
-
-@noindent
-or
-
-@display
-My parser includes support for an @samp{#include}-like feature, in
-which case I run @code{yyparse} from @code{yyparse}. This fails
-although I did specify I needed a @code{%pure-parser}.
-@end display
-
-These problems typically come not from Bison itself, but from
-Lex-generated scanners. Because these scanners use large buffers for
-speed, they might not notice a change of input file. As a
-demonstration, consider the following source file,
-@file{first-line.l}:
-
-@verbatim
-%{
-#include <stdio.h>
-#include <stdlib.h>
-%}
-%%
-.*\n ECHO; return 1;
-%%
-int
-yyparse (char const *file)
-{
- yyin = fopen (file, "r");
- if (!yyin)
- exit (2);
- /* One token only. */
- yylex ();
- if (fclose (yyin) != 0)
- exit (3);
- return 0;
-}
-
-int
-main (void)
-{
- yyparse ("input");
- yyparse ("input");
- return 0;
-}
-@end verbatim
-
-@noindent
-If the file @file{input} contains
-
-@verbatim
-input:1: Hello,
-input:2: World!
-@end verbatim
-
-@noindent
-then instead of getting the first line twice, you get:
-
-@example
-$ @kbd{flex -ofirst-line.c first-line.l}
-$ @kbd{gcc -ofirst-line first-line.c -ll}
-$ @kbd{./first-line}
-input:1: Hello,
-input:2: World!
-@end example
-
-Therefore, whenever you change @code{yyin}, you must tell the
-Lex-generated scanner to discard its current buffer and switch to the
-new one. This depends upon your implementation of Lex; see its
-documentation for more. For Flex, it suffices to call
-@samp{YY_FLUSH_BUFFER} after each change to @code{yyin}. If your
-Flex-generated scanner needs to read from several input streams to
-handle features like include files, you might consider using Flex
-functions like @samp{yy_switch_to_buffer} that manipulate multiple
-input buffers.
-
-If your Flex-generated scanner uses start conditions (@pxref{Start
-conditions, , Start conditions, flex, The Flex Manual}), you might
-also want to reset the scanner's state, i.e., go back to the initial
-start condition, through a call to @samp{BEGIN (0)}.
-
-@node Strings are Destroyed
-@section Strings are Destroyed
-
-@display
-My parser seems to destroy old strings, or maybe it loses track of
-them. Instead of reporting @samp{"foo", "bar"}, it reports
-@samp{"bar", "bar"}, or even @samp{"foo\nbar", "bar"}.
-@end display
-
-This error is probably the single most frequent ``bug report'' sent to
-Bison lists, but is only concerned with a misunderstanding of the role
-of the scanner. Consider the following Lex code:
-
-@verbatim
-%{
-#include <stdio.h>
-char *yylval = NULL;
-%}
-%%
-.* yylval = yytext; return 1;
-\n /* IGNORE */
-%%
-int
-main ()
-{
- /* Similar to using $1, $2 in a Bison action. */
- char *fst = (yylex (), yylval);
- char *snd = (yylex (), yylval);
- printf ("\"%s\", \"%s\"\n", fst, snd);
- return 0;
-}
-@end verbatim
-
-If you compile and run this code, you get:
-
-@example
-$ @kbd{flex -osplit-lines.c split-lines.l}
-$ @kbd{gcc -osplit-lines split-lines.c -ll}
-$ @kbd{printf 'one\ntwo\n' | ./split-lines}
-"one
-two", "two"
-@end example
-
-@noindent
-this is because @code{yytext} is a buffer provided for @emph{reading}
-in the action, but if you want to keep it, you have to duplicate it
-(e.g., using @code{strdup}). Note that the output may depend on how
-your implementation of Lex handles @code{yytext}. For instance, when
-given the Lex compatibility option @option{-l} (which triggers the
-option @samp{%array}) Flex generates a different behavior:
-
-@example
-$ @kbd{flex -l -osplit-lines.c split-lines.l}
-$ @kbd{gcc -osplit-lines split-lines.c -ll}
-$ @kbd{printf 'one\ntwo\n' | ./split-lines}
-"two", "two"

-@node Implementing Gotos/Loops
-@section Implementing Gotos/Loops
-
-@display
-My simple calculator supports variables, assignments, and functions,
-but how can I implement gotos, or loops?
-@end display
-
-Although very pedagogical, the examples included in the document blur
-the distinction to make between the parser---whose job is to recover
-the structure of a text and to transmit it to subsequent modules of
-the program---and the processing (such as the execution) of this
-structure. This works well with so called straight line programs,
-i.e., precisely those that have a straightforward execution model:
-execute simple instructions one after the others.
-
-@cindex abstract syntax tree
-@cindex @acronym{AST}
-If you want a richer model, you will probably need to use the parser
-to construct a tree that does represent the structure it has
-recovered; this tree is usually called the @dfn{abstract syntax tree},
-or @dfn{@acronym{AST}} for short. Then, walking through this tree,
-traversing it in various ways, will enable treatments such as its
-execution or its translation, which will result in an interpreter or a
-compiler.
-
-This topic is way beyond the scope of this manual, and the reader is
-invited to consult the dedicated literature.

-
-@node Multiple start-symbols
-@section Multiple start-symbols
-
-@display
-I have several closely related grammars, and I would like to share their
-implementations. In fact, I could use a single grammar but with
-multiple entry points.
-@end display
-
-Bison does not support multiple start-symbols, but there is a very
-simple means to simulate them. If @code{foo} and @code{bar} are the two
-pseudo start-symbols, then introduce two new tokens, say
-@code{START_FOO} and @code{START_BAR}, and use them as switches from the
-real start-symbol:
-
-@example
-%token START_FOO START_BAR;
-%start start;
-start: START_FOO foo
- | START_BAR bar;
-@end example
-
-These tokens prevents the introduction of new conflicts. As far as the
-parser goes, that is all that is needed.
-
-Now the difficult part is ensuring that the scanner will send these
-tokens first. If your scanner is hand-written, that should be
-straightforward. If your scanner is generated by Lex, them there is
-simple means to do it: recall that anything between @samp{%@{ ... %@}}
-after the first @code{%%} is copied verbatim in the top of the generated
-@code{yylex} function. Make sure a variable @code{start_token} is
-available in the scanner (e.g., a global variable or using
-@code{%lex-param} etc.), and use the following:
-
-@example
- /* @r{Prologue.} */
-%%
-%@{
- if (start_token)
- @{
- int t = start_token;
- start_token = 0;
- return t;
- @}
-%@}

-
-In the all-too-common case where your code may run on a host with a
-limited stack and with unreliable stack-overflow checking, you should
-set @code{YYMAXDEPTH} to a value that cannot possibly result in
-unchecked stack overflow on any of your target hosts when
-@code{alloca} is called. You can inspect the code that Bison

-by John Backus, and slightly improved by Peter Naur in his 1960-01-02
-committee document contributing to what became the Algol 60 report.
-@xref{Language and Grammar, ,Languages and Context-Free Grammars}.
-
-@item Context-free grammars
-Grammars specified as rules that can be applied regardless of context.
-Thus, if there is a rule which says that an integer can be used as an
-expression, integers are allowed @emph{anywhere} an expression is
-permitted. @xref{Language and Grammar, ,Languages and Context-Free
-Grammars}.
-
-@item Dynamic allocation
-Allocation of memory that occurs during execution, rather than at
-compile time or on entry to a function.
-
-@item Empty string
-Analogous to the empty set in set theory, the empty string is a
-character string of length zero.
-
-@item Finite-state stack machine
-A ``machine'' that has discrete states in which it is said to exist at
-each instant in time. As input to the machine is processed, the

-parsed, and the states correspond to various stages in the grammar
-rules. @xref{Algorithm, ,The Bison Parser Algorithm}.
-
-@item Generalized @acronym{LR} (@acronym{GLR})
-A parsing algorithm that can handle all context-free grammars, including those
-that are not @acronym{LALR}(1). It resolves situations that Bison's
-usual @acronym{LALR}(1)
-algorithm cannot by effectively splitting off multiple parsers, trying all
-possible parsers, and discarding those that fail in the light of additional
-right context. @xref{Generalized LR Parsing, ,Generalized
-@acronym{LR} Parsing}.
-
-@item Grouping
-A language construct that is (in general) grammatically divisible;
-for example, `expression' or `declaration' in C@.

-@item Infix operator
-An arithmetic operator that is placed between the operands on which it
-performs some operation.
-
-@item Input stream

-@samp{c}. @xref{Precedence, ,Operator Precedence}.
-
-@item Left recursion
-A rule whose result symbol is also its first component symbol; for
-example, @samp{expseq1 : expseq1 ',' exp;}. @xref{Recursion, ,Recursive
-Rules}.
-
-@item Left-to-right parsing
-Parsing a sentence of a language by analyzing it token by token from
-left to right. @xref{Algorithm, ,The Bison Parser Algorithm}.

-@xref{Lexical, ,The Lexical Analyzer Function @code{yylex}}.
-
-@item Lexical tie-in
-A flag, set by actions in the grammar rules, which alters the way
-tokens are parsed. @xref{Lexical Tie-ins}.
-
-@item Literal string token
-A token which consists of two or more fixed characters. @xref{Symbols}.

-look-ahead is needed to disambiguate the parsing of any piece of input.
-
-@item Nonterminal symbol
-A grammar symbol standing for a grammatical construct that can
-be expressed through rules in terms of smaller constructs; in other
-words, a construct that is not a token. @xref{Symbols}.
-
-@item Parser
-A function that recognizes valid sentences of a language by analyzing
-the syntax structure of a set of tokens passed to it from a lexical
-analyzer.
-
-@item Postfix operator
-An arithmetic operator that is placed after the operands upon which it
-performs some operation.
-
-@item Reduction
-Replacing a string of nonterminals and/or terminals with a single
-nonterminal, according to a grammar rule. @xref{Algorithm, ,The Bison
-Parser Algorithm}.
-
-@item Reentrant
-A reentrant subprogram is a subprogram which can be in invoked any
-number of times in parallel, without interference between the various
-invocations. @xref{Pure Decl, ,A Pure (Reentrant) Parser}.
-

-taken for each instance of the language, i.e., the meaning of
-each statement. @xref{Semantics, ,Defining Language Semantics}.
-
-@item Shift
-A parser is said to shift when it makes the choice of analyzing
-further input from the stream rather than reducing immediately some
-already-recognized rule. @xref{Algorithm, ,The Bison Parser Algorithm}.
-
-@item Single-character literal
-A single character that is recognized and interpreted as is.
-@xref{Grammar in Bison, ,From Formal Rules to Bison Input}.

-The nonterminal symbol that stands for a complete valid utterance in
-the language being parsed. The start symbol is usually listed as the
-first nonterminal symbol in a language specification.
-@xref{Start Decl, ,The Start-Symbol}.
-
-@item Symbol table
-A data structure where symbol names and associated data are stored
-during parsing to allow for recognition and use of existing
-information in repeated uses of a symbol. @xref{Multi-function Calc}.
-
-@item Syntax error
-An error encountered during parsing of an input stream due to invalid
-syntax. @xref{Error Recovery}.
-
-@item Token
-A basic, grammatically indivisible unit of a language. The symbol
-that describes a token in the grammar is a terminal symbol.
-The input of the Bison parser is a stream of tokens which comes from
-the lexical analyzer. @xref{Symbols}.
-
-@item Terminal symbol
-A grammar symbol that has no rules in the grammar and therefore is
-grammatically indivisible. The piece of text it represents is a token.

-PREAMBLE
-
-The purpose of this License is to make a manual, textbook, or other
-functional and useful document @dfn{free} in the sense of freedom: to
-assure everyone the effective freedom to copy and redistribute it,
-with or without modifying it, either commercially or noncommercially.
-Secondarily, this License preserves for the author and publisher a way
-to get credit for their work, while not being considered responsible
-for modifications made by others.
-
-This License is a kind of ``copyleft'', which means that derivative
-works of the document must themselves be free in the same sense. It
-complements the GNU General Public License, which is a copyleft
-license designed for free software.
-
-We have designed this License in order to use it for manuals for free
-software, because free software needs free documentation: a free
-program should come with manuals providing the same freedoms that the
-software does. But this License is not limited to software manuals;
-it can be used for any textual work, regardless of subject matter or
-whether it is published as a printed book. We recommend this License
-principally for works whose purpose is instruction or reference.
-
-@item
-APPLICABILITY AND DEFINITIONS
-
-This License applies to any manual or other work, in any medium, that
-contains a notice placed by the copyright holder saying it can be
-distributed under the terms of this License. Such a notice grants a
-world-wide, royalty-free license, unlimited in duration, to use that
-work under the conditions stated herein. The ``Document'', below,
-refers to any such manual or work. Any member of the public is a
-licensee, and is addressed as ``you''. You accept the license if you
-copy, modify or distribute the work in a way requiring permission
-under copyright law.
-
-A ``Modified Version'' of the Document means any work containing the
-Document or a portion of it, either copied verbatim, or with
-modifications and/or translated into another language.
-
-A ``Secondary Section'' is a named appendix or a front-matter section
-of the Document that deals exclusively with the relationship of the
-publishers or authors of the Document to the Document's overall
-subject (or to related matters) and contains nothing that could fall
-directly within that overall subject. (Thus, if the Document is in
-part a textbook of mathematics, a Secondary Section may not explain
-any mathematics.) The relationship could be a matter of historical
-connection with the subject or with related matters, or of legal,
-commercial, philosophical, ethical or political position regarding
-them.
-
-The ``Invariant Sections'' are certain Secondary Sections whose titles
-are designated, as being those of Invariant Sections, in the notice
-that says that the Document is released under this License. If a
-section does not fit the above definition of Secondary then it is not
-allowed to be designated as Invariant. The Document may contain zero
-Invariant Sections. If the Document does not identify any Invariant
-Sections then there are none.
-
-The ``Cover Texts'' are certain short passages of text that are listed,
-as Front-Cover Texts or Back-Cover Texts, in the notice that says that
-the Document is released under this License. A Front-Cover Text may
-be at most 5 words, and a Back-Cover Text may be at most 25 words.
-
-A ``Transparent'' copy of the Document means a machine-readable copy,
-represented in a format whose specification is available to the
-general public, that is suitable for revising the document
-straightforwardly with generic text editors or (for images composed of
-pixels) generic paint programs or (for drawings) some widely available
-drawing editor, and that is suitable for input to text formatters or
-for automatic translation to a variety of formats suitable for input
-to text formatters. A copy made in an otherwise Transparent file
-format whose markup, or absence of markup, has been arranged to thwart
-or discourage subsequent modification by readers is not Transparent.
-An image format is not Transparent if used for any substantial amount
-of text. A copy that is not ``Transparent'' is called ``Opaque''.
-
-Examples of suitable formats for Transparent copies include plain
-@sc{ascii} without markup, Texinfo input format, La@TeX{} input
-format, @acronym{SGML} or @acronym{XML} using a publicly available
-@acronym{DTD}, and standard-conforming simple @acronym{HTML},
-PostScript or @acronym{PDF} designed for human modification. Examples
-of transparent image formats include @acronym{PNG}, @acronym{XCF} and
-@acronym{JPG}. Opaque formats include proprietary formats that can be
-read and edited only by proprietary word processors, @acronym{SGML} or
-@acronym{XML} for which the @acronym{DTD} and/or processing tools are
-not generally available, and the machine-generated @acronym{HTML},
-PostScript or @acronym{PDF} produced by some word processors for
-output purposes only.
-
-The ``Title Page'' means, for a printed book, the title page itself,
-plus such following pages as are needed to hold, legibly, the material
-this License requires to appear in the title page. For works in
-formats which do not have any title page as such, ``Title Page'' means
-the text near the most prominent appearance of the work's title,
-preceding the beginning of the body of the text.
-
-A section ``Entitled XYZ'' means a named subunit of the Document whose
-title either is precisely XYZ or contains XYZ in parentheses following
-text that translates XYZ in another language. (Here XYZ stands for a
-specific section name mentioned below, such as ``Acknowledgements'',
-``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
-of such a section when you modify the Document means that it remains a
-section ``Entitled XYZ'' according to this definition.
-
-The Document may include Warranty Disclaimers next to the notice which
-states that this License applies to the Document. These Warranty
-Disclaimers are considered to be included by reference in this
-License, but only as regards disclaiming warranties: any other
-implication that these Warranty Disclaimers may have is void and has
-no effect on the meaning of this License.

-VERBATIM COPYING
-
-You may copy and distribute the Document in any medium, either
-commercially or noncommercially, provided that this License, the
-copyright notices, and the license notice saying this License applies
-to the Document are reproduced in all copies, and that you add no other
-conditions whatsoever to those of this License. You may not use
-technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute. However, you may accept
-compensation in exchange for copies. If you distribute a large enough

-COPYING IN QUANTITY
-
-If you publish printed copies (or copies in media that commonly have
-printed covers) of the Document, numbering more than 100, and the
-Document's license notice requires Cover Texts, you must enclose the
-copies in covers that carry, clearly and legibly, all these Cover
-Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
-the back cover. Both covers must also clearly and legibly identify
-you as the publisher of these copies. The front cover must present
-the full title with all words of the title equally prominent and
-visible. You may add other material on the covers in addition.
-Copying with changes limited to the covers, as long as they preserve
-the title of the Document and satisfy these conditions, can be treated
-as verbatim copying in other respects.
-
-If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-
-If you publish or distribute Opaque copies of the Document numbering
-more than 100, you must either include a machine-readable Transparent
-copy along with each Opaque copy, or state in or with each Opaque copy
-a computer-network location from which the general network-using
-public has access to download using public-standard network protocols
-a complete Transparent copy of the Document, free of added material.
-If you use the latter option, you must take reasonably prudent steps,
-when you begin distribution of Opaque copies in quantity, to ensure
-that this Transparent copy will remain thus accessible at the stated
-location until at least one year after the last time you distribute an
-Opaque copy (directly or through your agents or retailers) of that
-edition to the public.
-
-It is requested, but not required, that you contact the authors of the
-Document well before redistributing any large number of copies, to give
-them a chance to provide you with an updated version of the Document.
-
-@item
-MODIFICATIONS
-
-You may copy and distribute a Modified Version of the Document under
-the conditions of sections 2 and 3 above, provided that you release
-the Modified Version under precisely this License, with the Modified
-Version filling the role of the Document, thus licensing distribution
-and modification of the Modified Version to whoever possesses a copy
-of it. In addition, you must do these things in the Modified Version:
-
-@enumerate A
-@item
-Use in the Title Page (and on the covers, if any) a title distinct
-from that of the Document, and from those of previous versions
-(which should, if there were any, be listed in the History section
-of the Document). You may use the same title as a previous version
-if the original publisher of that version gives permission.
-
-@item
-List on the Title Page, as authors, one or more persons or entities
-responsible for authorship of the modifications in the Modified
-Version, together with at least five of the principal authors of the
-Document (all of its principal authors, if it has fewer than five),
-unless they release you from this requirement.
-
-@item
-State on the Title page the name of the publisher of the
-Modified Version, as the publisher.
-
-@item
-Preserve all the copyright notices of the Document.
-
-@item
-Add an appropriate copyright notice for your modifications
-adjacent to the other copyright notices.
-
-@item
-Include, immediately after the copyright notices, a license notice
-giving the public permission to use the Modified Version under the
-terms of this License, in the form shown in the Addendum below.
-
-@item
-Preserve in that license notice the full lists of Invariant Sections
-and required Cover Texts given in the Document's license notice.
-
-@item
-Include an unaltered copy of this License.
-
-@item
-Preserve the section Entitled ``History'', Preserve its Title, and add
-to it an item stating at least the title, year, new authors, and
-publisher of the Modified Version as given on the Title Page. If
-there is no section Entitled ``History'' in the Document, create one
-stating the title, year, authors, and publisher of the Document as
-given on its Title Page, then add an item describing the Modified
-Version as stated in the previous sentence.
-
-@item
-Preserve the network location, if any, given in the Document for
-public access to a Transparent copy of the Document, and likewise
-the network locations given in the Document for previous versions
-it was based on. These may be placed in the ``History'' section.
-You may omit a network location for a work that was published at
-least four years before the Document itself, or if the original
-publisher of the version it refers to gives permission.
-
-@item
-For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
-the Title of the section, and preserve in the section all the
-substance and tone of each of the contributor acknowledgements and/or
-dedications given therein.
-
-@item
-Preserve all the Invariant Sections of the Document,
-unaltered in their text and in their titles. Section numbers
-or the equivalent are not considered part of the section titles.
-
-@item
-Delete any section Entitled ``Endorsements''. Such a section
-may not be included in the Modified Version.
-
-@item
-Do not retitle any existing section to be Entitled ``Endorsements'' or
-to conflict in title with any Invariant Section.
-
-@item
-Preserve any Warranty Disclaimers.
-@end enumerate
-
-If the Modified Version includes new front-matter sections or
-appendices that qualify as Secondary Sections and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant. To do this, add their titles to the
-list of Invariant Sections in the Modified Version's license notice.
-These titles must be distinct from any other section titles.
-
-You may add a section Entitled ``Endorsements'', provided it contains
-nothing but endorsements of your Modified Version by various
-parties---for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.
-
-You may add a passage of up to five words as a Front-Cover Text, and a
-passage of up to 25 words as a Back-Cover Text, to the end of the list
-of Cover Texts in the Modified Version. Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or
-through arrangements made by) any one entity. If the Document already
-includes a cover text for the same cover, previously added by you or
-by arrangement made by the same entity you are acting on behalf of,
-you may not add another; but you may replace the old one, on explicit
-permission from the previous publisher that added the old one.
-
-The author(s) and publisher(s) of the Document do not by this License
-give permission to use their names for publicity for or to assert or
-imply endorsement of any Modified Version.
-
-@item
-COMBINING DOCUMENTS
-
-You may combine the Document with other documents released under this
-License, under the terms defined in section 4 above for modified
-versions, provided that you include in the combination all of the
-Invariant Sections of all of the original documents, unmodified, and
-list them all as Invariant Sections of your combined work in its
-license notice, and that you preserve all their Warranty Disclaimers.
-
-The combined work need only contain one copy of this License, and
-multiple identical Invariant Sections may be replaced with a single
-copy. If there are multiple Invariant Sections with the same name but
-different contents, make the title of each such section unique by
-adding at the end of it, in parentheses, the name of the original
-author or publisher of that section if known, or else a unique number.
-Make the same adjustment to the section titles in the list of
-Invariant Sections in the license notice of the combined work.
-
-In the combination, you must combine any sections Entitled ``History''
-in the various original documents, forming one section Entitled
-``History''; likewise combine any sections Entitled ``Acknowledgements'',
-and any sections Entitled ``Dedications''. You must delete all
-sections Entitled ``Endorsements.''
-
-@item
-COLLECTIONS OF DOCUMENTS
-
-You may make a collection consisting of the Document and other documents
-released under this License, and replace the individual copies of this
-License in the various documents with a single copy that is included in
-the collection, provided that you follow the rules of this License for
-verbatim copying of each of the documents in all other respects.
-
-You may extract a single document from such a collection, and distribute
-it individually under this License, provided you insert a copy of this
-License into the extracted document, and follow this License in all
-other respects regarding verbatim copying of that document.
-
-@item
-AGGREGATION WITH INDEPENDENT WORKS
-
-A compilation of the Document or its derivatives with other separate
-and independent documents or works, in or on a volume of a storage or
-distribution medium, is called an ``aggregate'' if the copyright
-resulting from the compilation is not used to limit the legal rights
-of the compilation's users beyond what the individual works permit.
-When the Document is included in an aggregate, this License does not
-apply to the other works in the aggregate which are not themselves
-derivative works of the Document.
-
-If the Cover Text requirement of section 3 is applicable to these
-copies of the Document, then if the Document is less than one half of
-the entire aggregate, the Document's Cover Texts may be placed on
-covers that bracket the Document within the aggregate, or the
-electronic equivalent of covers if the Document is in electronic form.
-Otherwise they must appear on printed covers that bracket the whole
-aggregate.
-
-@item
-TRANSLATION
-
-Translation is considered a kind of modification, so you may
-distribute translations of the Document under the terms of section 4.
-Replacing Invariant Sections with translations requires special
-permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections. You may include a
-translation of this License, and all the license notices in the
-Document, and any Warranty Disclaimers, provided that you also include
-the original English version of this License and the original versions
-of those notices and disclaimers. In case of a disagreement between
-the translation and the original version of this License or a notice
-or disclaimer, the original version will prevail.
-
-If a section in the Document is Entitled ``Acknowledgements'',
-``Dedications'', or ``History'', the requirement (section 4) to Preserve
-its Title (section 1) will typically require changing the actual
-title.
-
-@item
-TERMINATION
-
-You may not copy, modify, sublicense, or distribute the Document except
-as expressly provided for under this License. Any other attempt to
-copy, modify, sublicense or distribute the Document is void, and will
-automatically terminate your rights under this License. However,
-parties who have received copies, or rights, from you under this
-License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-@item
-FUTURE REVISIONS OF THIS LICENSE
-
-The Free Software Foundation may publish new, revised versions
-of the GNU Free Documentation License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns. See
-@uref{http://www.gnu.org/copyleft/}.
-
-Each version of the License is given a distinguishing version number.
-If the Document specifies that a particular numbered version of this
-License ``or any later version'' applies to it, you have the option of
-following the terms and conditions either of that specified version or
-of any later version that has been published (not as a draft) by the
-Free Software Foundation. If the Document does not specify a version
-number of this License, you may choose any version ever published (not
-as a draft) by the Free Software Foundation.

- Texts. A copy of the license is included in the section entitled ``GNU
- Free Documentation License''.
-@end group
-@end smallexample
-
-If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
-replace the ``with...Texts.'' line with this:

-
-If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-
-If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License,
-to permit their use in free software.

-
-@unnumberedsec Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software---to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.

-@iftex
-@unnumberedsec TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-@end iftex
-@ifinfo
-@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-@end ifinfo
-
-@enumerate 0
-@item
-This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The ``Program'', below,
-refers to any such program or work, and a ``work based on the Program''
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term ``modification''.) Each licensee is addressed as ``you''.
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-@item
-You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-@item
-You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-@enumerate a
-@item
-You must cause the modified files to carry prominent notices
-stating that you changed the files and the date of any change.
-
-@item
-You must cause any work that you distribute or publish, that in
-whole or in part contains or is derived from the Program or any
-part thereof, to be licensed as a whole at no charge to all third
-parties under the terms of this License.
-
-@item
-If the modified program normally reads commands interactively
-when run, you must cause it, when started running for such
-interactive use in the most ordinary way, to print or display an
-announcement including an appropriate copyright notice and a
-notice that there is no warranty (or else, saying that you provide
-a warranty) and that users may redistribute the program under
-these conditions, and telling the user how to view a copy of this
-License. (Exception: if the Program itself is interactive but
-does not normally print such an announcement, your work based on
-the Program is not required to print an announcement.)
-@end enumerate
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-@item
-You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-@enumerate a
-@item
-Accompany it with the complete corresponding machine-readable
-source code, which must be distributed under the terms of Sections
-1 and 2 above on a medium customarily used for software interchange; or,
-
-@item
-Accompany it with a written offer, valid for at least three
-years, to give any third party, for a charge no more than your
-cost of physically performing source distribution, a complete
-machine-readable copy of the corresponding source code, to be
-distributed under the terms of Sections 1 and 2 above on a medium
-customarily used for software interchange; or,
-
-@item
-Accompany it with the information you received as to the offer
-to distribute corresponding source code. (This alternative is
-allowed only for noncommercial distribution and only if you
-received the program in object code or executable form with such
-an offer, in accord with Subsection b above.)
-@end enumerate
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-@item
-You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-@item
-You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-@item
-Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-@item
-If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-@item
-If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-@item
-The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and ``any
-later version'', you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-@item
-If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.

-@unnumberedsec Appendix: How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the ``copyright'' line and a pointer to where the full notice is found.

-(at your option) any later version.
-
-This program is distributed in the hope that it will be useful,
-but WITHOUT ANY WARRANTY; without even the implied warranty of
-MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
-GNU General Public License for more details.

-\section{Starting Bison}
-%***********************
-
-To use Bison, type: \kbd{bison {\it filename}}
-
-Options can be used as: \kbd{bison {\it options} {\it filename}}
-
-\section{Command Line Options}
-%*****************************
-
-\key{Display usage information.} {-h}
-\key{Display version information.} {-V}
-\key{Generate token and {\tt YYSTYPE} definitions.} {-d}
-\key{Prepend a prefix to external symbols.} {-p {\it prefix}}
-\key{Don't put {\tt \#line} directives in the parser.} {-l}
-\key{Specify the output file.} {-o {\it filename}}
-\key{Debug or {\it trace} mode.} {-t}
-\key{Verbose description of the parser.} {-v}
-\key{Emulate {\tt yacc} (generate {\tt y.tab.*} files).} {-y}
-
-\vskip .10truein
-{\bf Note:} The token and {\tt YYSTYPE} definitions are generated
-to a file called {\tt y.tab.h} if the {\tt -y} option is used,
-otherwise it will have the format {\tt {\it name}.tab.h}, where
-{\it name} is the leading part of the parser definition filename.
-
-\section{Definitions}
-%********************
-
-\key{Declare a terminal symbol.}{\%token <{\it t\/}>
- {\it n}}
-
-\key{Declare a terminal symbol, and define its association.}
- {{\it association} <{\it t\/}> {\it n}}
-
-\vskip .2\baselineskip
-\key{Generate a reentrant (pure) parser.}
- {\%pure_parser}
-
-\key{Define the union of all data types used in the parser.}
- {\%union\{{\it field list}\} }
-
-\vskip .2\baselineskip
-\key{Tell {\tt bison} where to start parsing.}
- {\%start {\it m}}
-
-\key{Tell {\tt bison} the data type of symbols.}
- {\%type <{\it t\/}> {\it s1}\dots{\it sn}}
-
-\vskip .10truein
-
-In the above, {\it t} is a {\it type} defined in the {\tt \%union}
-definition, {\it n} is a {\it terminal} symbol name, {\it m} is a
-{\it non-terminal} symbol name, and {\it association} can be one of
-{\tt \%left}, {\tt \%right}, or {\tt \%nonassoc}.
-
-\vskip .10truein
-
-The {\tt <{\it t\/}>} after {\tt \%token, \%left, \%right} and {\tt
- \%nonassoc} is optional. Additionally, precedence may be overridden
-in the rules with {\tt \%prec} commands.
-
-\section{Parser Definition Files}
-%*********************************
-
-The general form for a parser definition is:
-
-\begincexample
-\{\%
- /* Initial C code. */
-\%\}
-
- {\it Token and type definitions}
-
-\%\%
-
- Rule definition 1
- \vdots
- Rule definition {\it n}
-
-\%\%
-
- /* Other C code. */
-\endcexample
-
-
-% Decrease standard baselineskip for the second page
- \baselineskip = .9\baselineskip
-
-\section {Rule definitions}
-%**************************
-
-Rules take the form:
-
-\vskip -\baselineskip
-\beginexample
- non-terminal : {\it statement} 1
- | {\it statement} 2
- \vdots
- | {\it statement n}
- ;
-\endexample
-
-Where {\it statements} can be either empty, or contain
-a mixture of C code (enclosed in {\tt \{...\}}), and the
-symbols that make up the non-terminal. For example:
-
-\vskip -\baselineskip
-\beginexample
- expression : number '$+$' number \{ \$\$ $=$ \$1 $+$ \$3 \}
- | number '$-$' number \{ \$\$ $=$ \$1 $-$ \$3 \}
- | number '$/$' number \{ \$\$ $=$ \$1 $/$ \$3 \}
- | number '$*$' number \{ \$\$ $=$ \$1 $*$ \$3 \}
- ;
-\endexample
-
-For altering the precedence of a symbol use:
-\vskip -\baselineskip
-
-\beginexample
- \%prec name
-\endexample
-
-For example:
-\vskip -\baselineskip
-\beginexample
- foo : gnu bar gnu \%prec bar
- ;
-\endexample
-
-\section{Grammar Variables and Symbols}
-%**************************************
-
-\key{Recognize an error \& continue parsing.}{error}
-\key{Access data associated with a symbol.} {\$\$, \$0\dots\${\it n}}
-\key{Access a field of the data union.} {\$\$.{\it t},
- \$0.{\it t}\dots\${\it n}.{\it t}}
-\key{Access symbol's location.} {@\$, @0\dots@{\it n}}
-\key{Access data's line location.} {@{\it x}.{\it line\_spec}}
-\key{Access data's column location.} {@{\it x}.{\it column\_spec}}
-
-
-\vskip .10truein
-%
-Where {\it t} is a type defined in the {\tt \%union}, {\it n} is a
-number, {\it x} is a number or \$, {\it line\_spec} one of {\tt
- first_line} and {\tt last_line}, and {\it column\_spec} is specified

- given in OPTSTRING.
-
- If an element of ARGV starts with '-', and is not exactly "-" or "--",
- then it is an option element. The characters of this element
- (aside from the initial '-') are option characters. If `getopt'
- is called repeatedly, it returns successively each of the option characters
- from each of the option elements.
-
- If `getopt' finds another option character, it returns that character,
- updating `optind' and `nextchar' so that the next call to `getopt' can
- resume the scan with the following option character or ARGV-element.
-
- If there are no more option characters, `getopt' returns -1.
- Then `optind' is the index in ARGV of the first ARGV-element
- that is not an option. (The ARGV-elements have been permuted
- so that those that are not options now come last.)
-
- OPTSTRING is a string containing the legitimate option characters.
- If an option character is seen that is not listed in OPTSTRING,
- return '?' after printing an error message. If you set `opterr' to
- zero, the error message is suppressed but we still return '?'.
-
- If a char in OPTSTRING is followed by a colon, that means it wants an arg,
- so the following text in the same ARGV-element, or the text of the following
- ARGV-element, is returned in `optarg'. Two colons mean an option that
- wants an optional arg; if there is text in the current ARGV-element,
- it is returned in `optarg', otherwise `optarg' is set to zero.
-
- If OPTSTRING starts with `-' or `+', it requests different methods of
- handling the non-option ARGV-elements.
- See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
- Long-named options begin with `--' instead of `-'.
- Their names may be abbreviated as long as the abbreviation is unique
- or is an exact match for some defined option. If they have an
- argument, it follows the option name in the same ARGV-element, separated
- from the option name by a `=', or else the in next ARGV-element.
- When `getopt' finds a long-named option, it returns 0 if that option's
- `flag' field is nonzero, the value of the option's `val' field
- if the `flag' field is zero.
-
- LONGOPTS is a vector of `struct option' terminated by an
- element containing a name which is zero.
-
- LONGIND returns the index in LONGOPT of the long-named option found.
- It is only valid when a long-named option has been found by the most
- recent call.
-
- If LONG_ONLY is nonzero, '-' as well as '--' can introduce
- long-named options.
-
- If POSIXLY_CORRECT is nonzero, behave as if the POSIXLY_CORRECT
- environment variable were set. */

-/* Summary:
-
-All the apparent functions defined here are macros. The idea
-is that you would use these pre-tested macros to solve a
-very specific set of problems, and they would run fast.
-Caution: no side-effects in arguments please!! They may be
-evaluated MANY times!!
-
-These macros operate a stack of objects. Each object starts life
-small, and may grow to maturity. (Consider building a word syllable
-by syllable.) An object can move while it is growing. Once it has
-been "finished" it never changes address again. So the "top of the
-stack" is typically an immature growing object, while the rest of the
-stack is of mature, fixed size and fixed address objects.
-
-These routines grab large chunks of memory, using a function you
-supply, called `obstack_chunk_alloc'. On occasion, they free chunks,
-by calling `obstack_chunk_free'. You must define them and declare
-them before using any obstack macros.
-
-Each independent stack is represented by a `struct obstack'.
-Each of the obstack macros expects a pointer to such a structure
-as the first argument.
-
-One motivation for this package is the problem of growing char strings
-in symbol tables. Unless you are "fascist pig with a read-only mind"
---Gosper's immortal quote from HAKMEM item 154, out of context--you
-would not like to put any arbitrary upper limit on the length of your
-symbols.
-
-In practice this often means you will build many short symbols and a
-few long symbols. At the time you are reading a symbol you don't know
-how long it is. One traditional method is to read a symbol into a
-buffer, realloc()ating the buffer every time you try to read a symbol
-that is longer than the buffer. This is beaut, but you still will
-want to copy the symbol from the buffer to a more permanent
-symbol-table entry say about half the time.
-
-With obstacks, you can work differently. Use one obstack for all symbol
-names. As you read a symbol, grow the name in the obstack gradually.
-When the name is complete, finalize it. Then, if the symbol exists already,
-free the newly read name.
-
-The way we do this is to take a large chunk, allocating memory from
-low addresses. When you want to build a symbol in the chunk you just
-add chars above the current "high water mark" in the chunk. When you
-have finished adding chars, because you got to the end of the symbol,
-you know how long the chars are, and you can create a new object.
-Mostly the chars will not burst over the highest address of the chunk,
-because you would typically expect a chunk to be (say) 100 times as
-long as an average object.
-
-In case that isn't clear, when we have enough chars to make up
-the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed)
-so we just point to it where it lies. No moving of chars is
-needed and this is the second win: potentially long strings need
-never be explicitly shuffled. Once an object is formed, it does not
-change its address during its lifetime.
-
-When the chars burst over a chunk boundary, we allocate a larger
-chunk, and then copy the partly formed object from the end of the old
-chunk to the beginning of the new larger chunk. We then carry on
-accreting characters to the end of the object as we normally would.
-
-A special macro is provided to add a single char at a time to a
-growing object. This allows the use of register variables, which
-break the ordinary 'growth' macro.
-
-Summary:
- We allocate large chunks.
- We carve out one object at a time from the current chunk.
- Once carved, an object never moves.
- We are free to append data of any size to the currently
- growing object.
- Exactly one object is growing in an obstack at any one time.
- You can run one obstack per control block.
- You may have as many control blocks as you dare.
- Because of the way we do it, you can `unwind' an obstack
- back to a previous state. (You may remove objects much
- as you would with a stack.)

- another variable is pushed on, the previous topmost variable is
- `paused' until the pushed variable is popped back off.

- - As a standalone timer, using timevar_start and timevar_stop.

-#ifndef VERIFY_H
-# define VERIFY_H 1
-
-/* Each of these macros verifies that its argument R is nonzero. To
- be portable, R should be an integer constant expression. Unlike
- assert (R), there is no run-time overhead.
-
- There are two macros, since no single macro can be used in all
- contexts in C. verify_true (R) is for scalar contexts, including
- integer constant expression contexts. verify (R) is for declaration
- contexts, e.g., the top level.
-
- Symbols ending in "__" are private to this header.
-
- The code below uses several ideas.
-
- * The first step is ((R) ? 1 : -1). Given an expression R, of
- integral or boolean or floating-point type, this yields an
- expression of integral type, whose value is later verified to be
- constant and nonnegative.
-
- * Next this expression W is wrapped in a type
- struct verify_type__ { unsigned int verify_error_if_negative_size__: W; }.
- If W is negative, this yields a compile-time error. No compiler can
- deal with a bit-field of negative size.
-
- One might think that an array size check would have the same
- effect, that is, that the type struct { unsigned int dummy[W]; }
- would work as well. However, inside a function, some compilers
- (such as C++ compilers and GNU C) allow local parameters and
- variables inside array size expressions. With these compilers,
- an array size check would not properly diagnose this misuse of
- the verify macro:
-
- void function (int n) { verify (n < 0); }
-
- * For the verify macro, the struct verify_type__ will need to
- somehow be embedded into a declaration. To be portable, this
- declaration must declare an object, a constant, a function, or a
- typedef name. If the declared entity uses the type directly,
- such as in
-
- struct dummy {...};
- typedef struct {...} dummy;
- extern struct {...} *dummy;
- extern void dummy (struct {...} *);
- extern struct {...} *dummy (void);
-
- two uses of the verify macro would yield colliding declarations
- if the entity names are not disambiguated. A workaround is to
- attach the current line number to the entity name:
-
- #define GL_CONCAT0(x, y) x##y
- #define GL_CONCAT(x, y) GL_CONCAT0 (x, y)
- extern struct {...} * GL_CONCAT(dummy,__LINE__);
-
- But this has the problem that two invocations of verify from
- within the same macro would collide, since the __LINE__ value
- would be the same for both invocations.
-
- A solution is to use the sizeof operator. It yields a number,
- getting rid of the identity of the type. Declarations like
-
- extern int dummy [sizeof (struct {...})];
- extern void dummy (int [sizeof (struct {...})]);
- extern int (*dummy (void)) [sizeof (struct {...})];
-
- can be repeated.
-
- * Should the implementation use a named struct or an unnamed struct?
- Which of the following alternatives can be used?
-
- extern int dummy [sizeof (struct {...})];
- extern int dummy [sizeof (struct verify_type__ {...})];
- extern void dummy (int [sizeof (struct {...})]);
- extern void dummy (int [sizeof (struct verify_type__ {...})]);
- extern int (*dummy (void)) [sizeof (struct {...})];
- extern int (*dummy (void)) [sizeof (struct verify_type__ {...})];
-
- In the second and sixth case, the struct type is exported to the
- outer scope; two such declarations therefore collide. GCC warns
- about the first, third, and fourth cases. So the only remaining
- possibility is the fifth case:
-
- extern int (*dummy (void)) [sizeof (struct {...})];
-
- * This implementation exploits the fact that GCC does not warn about
- the last declaration mentioned above. If a future version of GCC
- introduces a warning for this, the problem could be worked around
- by using code specialized to GCC, e.g.,:
-
- #if 4 <= __GNUC__
- # define verify(R) \
- extern int (* verify_function__ (void)) \
- [__builtin_constant_p (R) && (R) ? 1 : -1]
- #endif
-
- * In C++, any struct definition inside sizeof is invalid.
- Use a template type to work around the problem. */
-
-
-/* Verify requirement R at compile-time, as an integer constant expression.
- Return 1. */
-
-# ifdef __cplusplus
-template <int w>
- struct verify_type__ { unsigned int verify_error_if_negative_size__: w; };

-dnl functionality.

-dnl gettext package package is covered by the GNU General Public License.
-dnl They are *not* in the public domain.

-
-dnl Macro to add for using GNU gettext.
-
-dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
-dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
-dnl default (if it is not specified or empty) is 'no-libtool'.
-dnl INTLSYMBOL should be 'external' for packages with no intl directory,
-dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
-dnl If INTLSYMBOL is 'use-libtool', then a libtool library
-dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
-dnl depending on --{enable,disable}-{shared,static} and on the presence of
-dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
-dnl $(top_builddir)/intl/libintl.a will be created.
-dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
-dnl implementations (in libc or libintl) without the ngettext() function
-dnl will be ignored. If NEEDSYMBOL is specified and is
-dnl 'need-formatstring-macros', then GNU gettext implementations that don't
-dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
-dnl INTLDIR is used to find the intl libraries. If empty,
-dnl the value `$(top_builddir)/intl/' is used.
-dnl
-dnl The result of the configuration is one of three cases:
-dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
-dnl and used.
-dnl Catalog format: GNU --> install in $(datadir)
-dnl Catalog extension: .mo after installation, .gmo in source tree
-dnl 2) GNU gettext has been found in the system's C library.
-dnl Catalog format: GNU --> install in $(datadir)
-dnl Catalog extension: .mo after installation, .gmo in source tree
-dnl 3) No internationalization, always use English msgid.
-dnl Catalog format: none
-dnl Catalog extension: none
-dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
-dnl The use of .gmo is historical (it was needed to avoid overwriting the
-dnl GNU format catalogs when building on a platform with an X/Open gettext),
-dnl but we keep it in order not to force irrelevant filename changes on the
-dnl maintainers.

-dnl that contains a configuration script generated by Autoconf, under

-
-dnl This file defines some "once only" variants of standard autoconf macros.
-dnl AC_CHECK_HEADERS_ONCE like AC_CHECK_HEADERS
-dnl AC_CHECK_FUNCS_ONCE like AC_CHECK_FUNCS
-dnl AC_CHECK_DECLS_ONCE like AC_CHECK_DECLS
-dnl AC_REQUIRE([AC_HEADER_STDC]) like AC_HEADER_STDC
-dnl The advantage is that the check for each of the headers/functions/decls
-dnl will be put only once into the 'configure' file. It keeps the size of
-dnl the 'configure' file down, and avoids redundant output when 'configure'
-dnl is run.
-dnl The drawback is that the checks cannot be conditionalized. If you write
-dnl if some_condition; then gl_CHECK_HEADERS(stdlib.h); fi
-dnl inside an AC_DEFUNed function, the gl_CHECK_HEADERS macro call expands to
-dnl empty, and the check will be inserted before the body of the AC_DEFUNed
-dnl function.
-
-dnl This is like onceonly.m4, except that it uses diversions to named sections

-#ifndef GRAM_H_
-# define GRAM_H_
-
-/* Representation of the grammar rules:
-
- NTOKENS is the number of tokens, and NVARS is the number of
- variables (nonterminals). NSYMS is the total number, ntokens +
- nvars.
-
- Each symbol (either token or variable) receives a symbol number.
- Numbers 0 to NTOKENS - 1 are for tokens, and NTOKENS to NSYMS - 1
- are for variables. Symbol number zero is the end-of-input token.
- This token is counted in ntokens. The true number of token values
- assigned is NTOKENS reduced by one for each alias declaration.
-
- The rules receive rule numbers 1 to NRULES in the order they are
- written. More precisely Bison augments the grammar with the
- initial rule, `$accept: START-SYMBOL $end', which is numbered 1,
- all the user rules are 2, 3 etc. Each time a rule number is
- presented to the user, we subtract 1, so *displayed* rule numbers
- are 0, 1, 2...
-
- Internally, we cannot use the number 0 for a rule because for
- instance RITEM stores both symbol (the RHS) and rule numbers: the
- symbols are shorts >= 0, and rule number are stored negative.
- Therefore 0 cannot be used, since it would be both the rule number
- 0, and the token $end).
-
- Actions are accessed via the rule number.
-
- The rules themselves are described by several arrays: amongst which
- RITEM, and RULES.
-
- RULES is an array of rules, whose members are:
-
- RULES[R].lhs -- the symbol of the left hand side of rule R.
-
- RULES[R].rhs -- the index in RITEM of the beginning of the portion
- for rule R.
-
- RULES[R].prec -- the symbol providing the precedence level of R.
-
- RULES[R].precsym -- the symbol attached (via %prec) to give its
- precedence to R. Of course, if set, it is equal to `prec', but we
- need to distinguish one from the other when reducing: a symbol used
- in a %prec is not useless.
-
- RULES[R].assoc -- the associativity of R.
-
- RULES[R].dprec -- the dynamic precedence level of R (for GLR
- parsing).
-
- RULES[R].merger -- index of merging function for R (for GLR
- parsing).
-
- RULES[R].line -- the line where R was defined.
-
- RULES[R].useful -- true iff the rule is used (i.e., false if thrown
- away by reduce).
-
- The right hand side is stored as symbol numbers in a portion of
- RITEM.
-
- The length of the portion is one greater than the number of symbols
- in the rule's right hand side. The last element in the portion
- contains minus R, which identifies it as the end of a portion and
- says which rule it is for.
-
- The portions of RITEM come in order of increasing rule number.
- NRITEMS is the total length of RITEM. Each element of RITEM is
- called an "item" and its index in RITEM is an item number.
-
- Item numbers are used in the finite state machine to represent
- places that parsing can get to.
-
- SYMBOLS[I]->prec records the precedence level of each symbol.
-
- Precedence levels are assigned in increasing order starting with 1
- so that numerically higher precedence values mean tighter binding
- as they ought to. Zero as a symbol or rule's precedence means none
- is assigned.
-
- Associativities are recorded similarly in SYMBOLS[I]->assoc. */

-
-/* These type definitions are used to represent a nondeterministic
- finite state machine that parses the specified grammar. This
- information is generated by the function generate_states in the
- file LR0.
-
- Each state of the machine is described by a set of items --
- particular positions in particular rules -- that are the possible
- places where parsing could continue when the machine is in this
- state. These symbols at these items are the allowable inputs that
- can follow now.
-
- A core represents one state. States are numbered in the NUMBER
- field. When generate_states is finished, the starting state is
- state 0 and NSTATES is the number of states. (FIXME: This sentence
- is no longer true: A transition to a state whose state number is
- NSTATES indicates termination.) All the cores are chained together
- and FIRST_STATE points to the first one (state 0).
-
- For each state there is a particular symbol which must have been
- the last thing accepted to reach that state. It is the
- ACCESSING_SYMBOL of the core.
-
- Each core contains a vector of NITEMS items which are the indices
- in the RITEMS vector of the items that are selected in this state.
-
- The two types of actions are shifts/gotos (push the look-ahead token
- and read another/goto to the state designated by a nterm) and
- reductions (combine the last n things on the stack via a rule,
- replace them with the symbol that the rule derives, and leave the
- look-ahead token alone). When the states are generated, these
- actions are represented in two other lists.
-
- Each transition structure describes the possible transitions out
- of one state, the state whose number is in the number field. Each
- contains a vector of numbers of the states that transitions can go
- to. The accessing_symbol fields of those states' cores say what
- kind of input leads to them.
-
- A transition to state zero should be ignored: conflict resolution
- deletes transitions by having them point to zero.
-
- Each reductions structure describes the possible reductions at the
- state whose number is in the number field. The data is a list of
- nreds rules, represented by their rule numbers. first_reduction
- points to the list of these structures.
-
- Conflict resolution can decide that certain tokens in certain
- states should explicitly be errors (for implementing %nonassoc).
- For each state, the tokens that are errors for this reason are
- recorded in an errs structure, which holds the token numbers.
-
- There is at least one goto transition present in state zero. It
- leads to a next-to-final state whose accessing_symbol is the
- grammar's start symbol. The next-to-final state has one shift to
- the final state, whose accessing_symbol is zero (end of input).
- The final state has one shift, which goes to the termination state.
- The reason for the extra state at the end is to placate the
- parser's strategy of making all decisions one token ahead of its
- actions. */

-/* The parser tables consist of these tables.
-
- YYTRANSLATE = vector mapping yylex's token numbers into bison's
- token numbers.
-
- YYTNAME = vector of string-names indexed by bison token number.
-
- YYTOKNUM = vector of yylex token numbers corresponding to entries
- in YYTNAME.
-
- YYRLINE = vector of line-numbers of all rules. For yydebug
- printouts.
-
- YYRHS = vector of items of all rules. This is exactly what RITEMS
- contains. For yydebug and for semantic parser.
-
- YYPRHS[R] = index in YYRHS of first item for rule R.
-
- YYR1[R] = symbol number of symbol that rule R derives.
-
- YYR2[R] = number of symbols composing right hand side of rule R.
-
- YYSTOS[S] = the symbol number of the symbol that leads to state S.
-
- YYDEFACT[S] = default rule to reduce with in state s, when YYTABLE
- doesn't specify something else to do. Zero means the default is an
- error.
-
- YYDEFGOTO[I] = default state to go to after a reduction of a rule
- that generates variable NTOKENS + I, except when YYTABLE specifies
- something else to do.
-
- YYPACT[S] = index in YYTABLE of the portion describing state S.
- The look-ahead token's type is used to index that portion to find
- out what to do.
-
- If the value in YYTABLE is positive, we shift the token and go to
- that state.
-
- If the value is negative, it is minus a rule number to reduce by.
-
- If the value is zero, the default action from YYDEFACT[S] is used.
-
- YYPGOTO[I] = the index in YYTABLE of the portion describing what to
- do after reducing a rule that derives variable I + NTOKENS. This
- portion is indexed by the parser state number, S, as of before the
- text for this nonterminal was read. The value from YYTABLE is the
- state to go to if the corresponding value in YYCHECK is S.
-
- YYTABLE = a vector filled with portions for different uses, found
- via YYPACT and YYPGOTO.
-
- YYCHECK = a vector indexed in parallel with YYTABLE. It indicates,
- in a roundabout way, the bounds of the portion you are trying to
- examine.
-
- Suppose that the portion of YYTABLE starts at index P and the index
- to be examined within the portion is I. Then if YYCHECK[P+I] != I,
- I is outside the bounds of what is actually allocated, and the
- default (from YYDEFACT or YYDEFGOTO) should be used. Otherwise,
- YYTABLE[P+I] should be used.
-
- YYFINAL = the state number of the termination state.
-
- YYLAST ( = high) the number of the last element of YYTABLE, i.e.,
- sizeof (YYTABLE) - 1. */
