-The lldb-enhanced gud.el is based on the emacs 22.3.1 version from Aquamacs 1.8c
-distribution.
-
-The gud-diffs.txt is the diff from the gud.el file from emacs 22.3.1.
-
-To use it, load the file from within emacs and type 'M-x lldb' to invoke lldb.
-
-The lldb-gud-window.tiff is a screen capture of the gud (with lldb) at work on
-Aquamacs distribution 2.1 by loading the gud.el in this directory and 'M-x lldb'
-on the ../../test/condition_break directory.

-;;; Commentary:
-
-;; The ancestral gdb.el was by W. Schelter <wfs@rascal.ics.utexas.edu> It was
-;; later rewritten by rms. Some ideas were due to Masanobu. Grand
-;; Unification (sdb/dbx support) by Eric S. Raymond <esr@thyrsus.com> Barry
-;; Warsaw <bwarsaw@cen.com> hacked the mode to use comint.el. Shane Hartman
-;; <shane@spr.com> added support for xdb (HPUX debugger). Rick Sladkey
-;; <jrs@world.std.com> wrote the GDB command completion code. Dave Love
-;; <d.love@dl.ac.uk> added the IRIX kluge, re-implemented the Mips-ish variant
-;; and added a menu. Brian D. Carlstrom <bdc@ai.mit.edu> combined the IRIX
-;; kluge with the gud-xdb-directories hack producing gud-dbx-directories.
-;; Derek L. Davies <ddavies@world.std.com> added support for jdb (Java
-;; debugger.)

-;; Of course you may use `gud-def' with any other debugger command, including
-;; user defined ones.
-
-;; A macro call like (gud-def FUNC CMD KEY DOC) expands to a form
-;; which defines FUNC to send the command CMD to the debugger, gives
-;; it the docstring DOC, and binds that function to KEY in the GUD
-;; major mode. The function is also bound in the global keymap with the
-;; GUD prefix.
-
-(defmacro gud-def (func cmd key &optional doc)
- "Define FUNC to be a command sending CMD and bound to KEY, with
-optional doc string DOC. Certain %-escapes in the string arguments
-are interpreted specially if present. These are:
-
- %f -- Name (without directory) of current source file.
- %F -- Name (without directory or extension) of current source file.
- %d -- Directory of current source file.
- %l -- Number of current source line.
- %e -- Text of the C lvalue or function-call expression surrounding point.
- %a -- Text of the hexadecimal address surrounding point.
- %b -- Text of the most recently created breakpoint id.
- %p -- Prefix argument to the command (if any) as a number.
- %c -- Fully qualified class name derived from the expression
- surrounding point (jdb only).

-;; JDB support.
-;;
-;; AUTHOR: Derek Davies <ddavies@world.std.com>
-;; Zoltan Kemenczy <zoltan@ieee.org;zkemenczy@rim.net>
-;;
-;; CREATED: Sun Feb 22 10:46:38 1998 Derek Davies.
-;; UPDATED: Nov 11, 2001 Zoltan Kemenczy
-;; Dec 10, 2002 Zoltan Kemenczy - added nested class support
-;;
-;; INVOCATION NOTES:
-;;
-;; You invoke jdb-mode with:
-;;
-;; M-x jdb <enter>
-;;
-;; It responds with:
-;;
-;; Run jdb (like this): jdb
-;;
-;; type any jdb switches followed by the name of the class you'd like to debug.
-;; Supply a fully qualfied classname (these do not have the ".class" extension)
-;; for the name of the class to debug (e.g. "COM.the-kind.ddavies.CoolClass").
-;; See the known problems section below for restrictions when specifying jdb
-;; command line switches (search forward for '-classpath').
-;;
-;; You should see something like the following:
-;;
-;; Current directory is ~/src/java/hello/
-;; Initializing jdb...
-;; 0xed2f6628:class(hello)
-;; >
-;;
-;; To set an initial breakpoint try:
-;;
-;; > stop in hello.main
-;; Breakpoint set in hello.main
-;; >
-;;
-;; To execute the program type:
-;;
-;; > run
-;; run hello
-;;
-;; Breakpoint hit: running ...
-;; hello.main (hello:12)
-;;
-;; Type M-n to step over the current line and M-s to step into it. That,
-;; along with the JDB 'help' command should get you started. The 'quit'
-;; JDB command will get out out of the debugger. There is some truly
-;; pathetic JDB documentation available at:
-;;
-;; http://java.sun.com/products/jdk/1.1/debugging/
-;;
-;; KNOWN PROBLEMS AND FIXME's:
-;;
-;; Not sure what happens with inner classes ... haven't tried them.
-;;
-;; Does not grok UNICODE id's. Only ASCII id's are supported.
-;;
-;; You must not put whitespace between "-classpath" and the path to
-;; search for java classes even though it is required when invoking jdb
-;; from the command line. See gud-jdb-massage-args for details.
-;; The same applies for "-sourcepath".
-;;
-;; Note: The following applies only if `gud-jdb-use-classpath' is nil;
-;; refer to the documentation of `gud-jdb-use-classpath' and
-;; `gud-jdb-classpath',`gud-jdb-sourcepath' variables for information
-;; on using the classpath for locating java source files.
-;;
-;; If any of the source files in the directories listed in
-;; gud-jdb-directories won't parse you'll have problems. Make sure
-;; every file ending in ".java" in these directories parses without error.
-;;
-;; All the .java files in the directories in gud-jdb-directories are
-;; syntactically analyzed each time gud jdb is invoked. It would be
-;; nice to keep as much information as possible between runs. It would
-;; be really nice to analyze the files only as neccessary (when the
-;; source needs to be displayed.) I'm not sure to what extent the former
-;; can be accomplished and I'm not sure the latter can be done at all
-;; since I don't know of any general way to tell which .class files are
-;; defined by which .java file without analyzing all the .java files.
-;; If anyone knows why JavaSoft didn't put the source file names in
-;; debuggable .class files please clue me in so I find something else
-;; to be spiteful and bitter about.

-;; --------------------
-;; (gdb) set args foo bar
-;; (gdb) -!-
-;; --------------------
-;; (the -!- marks the location of point), and we type `C-x SPC' in a

-;; --------------------
-;; (gdb) set args foo bar
-;; Breakpoint 1 at 0x92: file make-docfile.c, line 49.
-;; (gdb) -!-
-;; --------------------
-;; Essentially, the old prompt is deleted, and the command's output
-;; and the new prompt take its place.
-;;
-;; Not echoing the command is easy enough; you send it directly using

-;; getting rid of the old prompt is trickier; you don't want to do it
-;; when you send the command, since that will result in an annoying
-;; flicker as the prompt is deleted, redisplay occurs while Emacs
-;; waits for a response from the debugger, and the new prompt is
-;; inserted. Instead, we'll wait until we actually get some output
-;; from the subprocess before we delete the prompt. If the command
-;; produced no output other than a new prompt, that prompt will most
-;; likely be in the first chunk of output received, so we will delete
-;; the prompt and then replace it with an identical one. If the
-;; command produces output, the prompt is moving anyway, so the
-;; flicker won't be annoying.
-;;
-;; So - when we want to delete the prompt upon receipt of the next
-;; chunk of debugger output, we position gud-delete-prompt-marker at
-;; the start of the prompt; the process filter will notice this, and

-
-After startup, the following commands are available in both the GUD
-interaction buffer and any source buffer GUD visits due to a breakpoint stop
-or step operation:
-
-\\[gud-break] sets a breakpoint at the current file and line. In the
-GUD buffer, the current file and line are those of the last breakpoint or
-step. In a source buffer, they are the buffer's file and current line.
-
-\\[gud-remove] removes breakpoints on the current file and line.
-
-\\[gud-refresh] displays in the source window the last line referred to
-in the gud buffer.
-
-\\[gud-step], \\[gud-next], and \\[gud-stepi] do a step-one-line,
-step-one-line (not entering function calls), and step-one-instruction
-and then update the source window with the current file and position.
-\\[gud-cont] continues execution.
-
-\\[gud-print] tries to find the largest C lvalue or function-call expression
-around point, and sends it to the debugger for value display.
-
-The above commands are common to all supported debuggers except xdb which
-does not support stepping instructions.
-
-Under gdb, sdb and xdb, \\[gud-tbreak] behaves exactly like \\[gud-break],
-except that the breakpoint is temporary; that is, it is removed when
-execution stops on it.
-
-Under gdb, dbx, xdb, and lldb, \\[gud-up] pops up through an enclosing stack
-frame. \\[gud-down] drops back down through one.
-
-If you are using gdb or xdb, \\[gud-finish] runs execution to the return from
