+Bionic is a very small C library because we have decided to *not* implement various features
+of the POSIX standard. we only add functions on a as-needed basis, and there are a few things
+we wish we'll never put in there.
+
+this file is here to document explicitely what we don't want to support in Bionic:
+
+- C++ exceptions are not supported. on embedded systems, they lead to extremely larger and
+  slower code for no good reason (even when so-called zero-cost exception schemes are
+  implemented, they enforce very large numbers of registers spills to the stack, even
+  in functions that do not throw an exception themselves).
+
+- pthread cancellation is *not* supported. this seemingly simple "feature" is the source
+  of much bloat and complexity in a C library. Besides, you'd better write correct
+  multi-threaded code instead of relying on this stuff.
+
+- pthread_once() doesn't support C++ exceptions thrown from the init function, or the init
+  function doing a fork().
+
+- locales and wide characters are not supported. we use ICU for all this i18n stuff, which
+  is much better than the ill-designed related C libraries functions.
+
+- at the moment, several user-account-related functions like getpwd are stubbed and return
+  the values corresponding to root. this will be fixed when we'll be able to have distinct
+  users on the Android filesystem. :-(
+
+  see bionic/stubs.c for the details

+Welcome to Bionic, Android small and custom C library for the Android platform
+
+Bionic is mainly a port of the BSD C library to our Linux kernel with the
+following additions/changes:
+
+- no support for locales
+- no support for wide chars (i.e. multi-byte characters)
+- its own smallish implementation of pthreads based on Linux futexes
+- support for x86, ARM and ARM thumb CPU instruction sets and kernel interfaces
+
+Bionic is released under the standard 3-clause BSD License
+
+Bionic doesn't want to implement all features of a traditional C library, we only
+add features to it as we need them, and we try to keep things as simple and small
+as possible. Our goal is not to support scaling to thousands of concurrent threads
+on multi-processors machines; we're running this on cell-phones, damnit !!
+
+Note that Bionic doesn't provide a libthread_db or a libm implementation.
+
+
+Adding new syscalls:
+====================
+
+Bionic provides the gensyscalls.py Python script to automatically generate syscall
+stubs from the list defined in the file SYSCALLS.TXT. You can thus add a new syscall
+by doing the following:
+
+- edit SYSCALLS.TXT
+- add a new line describing your syscall, it should look like:
+
+   return_type  syscall_name(parameters)    syscall_number
+
+- in the event where you want to differentiate the syscall function from its entry name,
+  use the alternate:
+
+   return_type  funcname:syscall_name(parameters)  syscall_number
+
+- additionally, if the syscall number is different between ARM and x86, use:
+
+   return_type  funcname[:syscall_name](parameters)   arm_number,x86_number
+
+- a syscall number can be -1 to indicate that the syscall is not implemented on
+  a given platform, for example:
+
+   void   __set_tls(void*)   arm_number,-1
+
+
+the comments in SYSCALLS.TXT contain more information about the line format
+
+You can also use the 'checksyscalls.py' script to check that all the syscall
+numbers you entered are correct. It does so by looking at the values defined in
+your Linux kernel headers. The script indicates where the values are incorrect
+and what is expected instead.

+# this file is used to list all the syscalls that will be supported by
+# the Bionic C library. It is used to automatically generate the syscall
+# stubs, the list of syscall constants (__NR_xxxx) and the content of <linux/_unitsd.h>
+#
+# each non comment line has the following format:
+#
+# return_type    func_name[:syscall_name[:call_id]]([parameter_list])  (#syscall_number|stub)
+#
+# note that:
+#      - syscall_name correspond to the name of the syscall, which may differ from
+#        the exported function name (example: the exit syscall is implemented by the _exit()
+#        function, which is not the same as the standard C exit() function which calls it)
+#        The call_id parameter, given that func_name and syscall_name have
+#        been provided, allows the user to specify dispatch style syscalls.
+#        For example, socket() syscall on i386 actually becomes:
+#          socketcall(__NR_socket, 1, *(rest of args on stack)).
+#
+#      - each parameter type is assumed to be stored on 32 bits, there is no plan to support
+#        64-bit architectures at the moment
+#
+#      - it there is "stub" instead of a syscall number, the tool will not generate any
+#        assembler template for the syscall; it's up to the bionic implementation to provide
+#        a relevant C stub
+#
+# the file is processed by a python script named gensyscalls.py

+
+* Version 2.8.3 Thu Sep 22 11:16:15 2005  Doug Lea  (dl at gee)
+
+   Note: There may be an updated version of this malloc obtainable at
+           ftp://gee.cs.oswego.edu/pub/misc/malloc.c
+         Check before installing!
+
+* Quickstart
+
+  This library is all in one file to simplify the most common usage:
+  ftp it, compile it (-O3), and link it into another program. All of
+  the compile-time options default to reasonable values for use on
+  most platforms.  You might later want to step through various
+  compile-time and dynamic tuning options.
+
+  For convenience, an include file for code using this malloc is at:
+     ftp://gee.cs.oswego.edu/pub/misc/malloc-2.8.3.h
+  You don't really need this .h file unless you call functions not
+  defined in your system include files.  The .h file contains only the
+  excerpts from this file needed for using this malloc on ANSI C/C++
+  systems, so long as you haven't changed compile-time options about
+  naming and tuning parameters.  If you do, then you can create your
+  own malloc.h that does include all settings by cutting at the point
+  indicated below. Note that you may already by default be using a C
+  library containing a malloc that is based on some version of this
+  malloc (for example in linux). You might still want to use the one
+  in this file to customize settings or to avoid overheads associated
+  with library versions.
+
+* Vital statistics:
+
+  Supported pointer/size_t representation:       4 or 8 bytes
+       size_t MUST be an unsigned type of the same width as
+       pointers. (If you are using an ancient system that declares
+       size_t as a signed type, or need it to be a different width
+       than pointers, you can use a previous release of this malloc
+       (e.g. 2.7.2) supporting these.)
+
+  Alignment:                                     8 bytes (default)
+       This suffices for nearly all current machines and C compilers.
+       However, you can define MALLOC_ALIGNMENT to be wider than this
+       if necessary (up to 128bytes), at the expense of using more space.
+
+  Minimum overhead per allocated chunk:   4 or  8 bytes (if 4byte sizes)
+                                          8 or 16 bytes (if 8byte sizes)
+       Each malloced chunk has a hidden word of overhead holding size
+       and status information, and additional cross-check word
+       if FOOTERS is defined.
+
+  Minimum allocated size: 4-byte ptrs:  16 bytes    (including overhead)
+                          8-byte ptrs:  32 bytes    (including overhead)
+
+       Even a request for zero bytes (i.e., malloc(0)) returns a
+       pointer to something of the minimum allocatable size.
+       The maximum overhead wastage (i.e., number of extra bytes
+       allocated than were requested in malloc) is less than or equal
+       to the minimum size, except for requests >= mmap_threshold that
+       are serviced via mmap(), where the worst case wastage is about
+       32 bytes plus the remainder from a system page (the minimal
+       mmap unit); typically 4096 or 8192 bytes.
+
+  Security: static-safe; optionally more or less
+       The "security" of malloc refers to the ability of malicious
+       code to accentuate the effects of errors (for example, freeing
+       space that is not currently malloc'ed or overwriting past the
+       ends of chunks) in code that calls malloc.  This malloc
+       guarantees not to modify any memory locations below the base of
+       heap, i.e., static variables, even in the presence of usage
+       errors.  The routines additionally detect most improper frees
+       and reallocs.  All this holds as long as the static bookkeeping
+       for malloc itself is not corrupted by some other means.  This
+       is only one aspect of security -- these checks do not, and
+       cannot, detect all possible programming errors.
+
+       If FOOTERS is defined nonzero, then each allocated chunk
+       carries an additional check word to verify that it was malloced
+       from its space.  These check words are the same within each
+       execution of a program using malloc, but differ across
+       executions, so externally crafted fake chunks cannot be
+       freed. This improves security by rejecting frees/reallocs that
+       could corrupt heap memory, in addition to the checks preventing
+       writes to statics that are always on.  This may further improve
+       security at the expense of time and space overhead.  (Note that
+       FOOTERS may also be worth using with MSPACES.)
+
+       By default detected errors cause the program to abort (calling
+       "abort()"). You can override this to instead proceed past
+       errors by defining PROCEED_ON_ERROR.  In this case, a bad free
+       has no effect, and a malloc that encounters a bad address
+       caused by user overwrites will ignore the bad address by
+       dropping pointers and indices to all known memory. This may
+       be appropriate for programs that should continue if at all
+       possible in the face of programming errors, although they may
+       run out of memory because dropped memory is never reclaimed.
+
+       If you don't like either of these options, you can define
+       CORRUPTION_ERROR_ACTION and USAGE_ERROR_ACTION to do anything
+       else. And if if you are sure that your program using malloc has
+       no errors or vulnerabilities, you can define INSECURE to 1,
+       which might (or might not) provide a small performance improvement.
+
+  Thread-safety: NOT thread-safe unless USE_LOCKS defined
+       When USE_LOCKS is defined, each public call to malloc, free,
+       etc is surrounded with either a pthread mutex or a win32
+       spinlock (depending on WIN32). This is not especially fast, and
+       can be a major bottleneck.  It is designed only to provide
+       minimal protection in concurrent environments, and to provide a
+       basis for extensions.  If you are using malloc in a concurrent
+       program, consider instead using ptmalloc, which is derived from
+       a version of this malloc. (See http://www.malloc.de).
+
+  System requirements: Any combination of MORECORE and/or MMAP/MUNMAP
+       This malloc can use unix sbrk or any emulation (invoked using
+       the CALL_MORECORE macro) and/or mmap/munmap or any emulation
+       (invoked using CALL_MMAP/CALL_MUNMAP) to get and release system
+       memory.  On most unix systems, it tends to work best if both
+       MORECORE and MMAP are enabled.  On Win32, it uses emulations
+       based on VirtualAlloc. It also uses common C library functions
+       like memset.
+
+  Compliance: I believe it is compliant with the Single Unix Specification
+       (See http://www.unix.org). Also SVID/XPG, ANSI C, and probably
+       others as well.
+
+* Overview of algorithms
+
+  This is not the fastest, most space-conserving, most portable, or
+  most tunable malloc ever written. However it is among the fastest
+  while also being among the most space-conserving, portable and
+  tunable.  Consistent balance across these factors results in a good
+  general-purpose allocator for malloc-intensive programs.
+
+  In most ways, this malloc is a best-fit allocator. Generally, it
+  chooses the best-fitting existing chunk for a request, with ties
+  broken in approximately least-recently-used order. (This strategy
+  normally maintains low fragmentation.) However, for requests less
+  than 256bytes, it deviates from best-fit when there is not an
+  exactly fitting available chunk by preferring to use space adjacent
+  to that used for the previous small request, as well as by breaking
+  ties in approximately most-recently-used order. (These enhance
+  locality of series of small allocations.)  And for very large requests
+  (>= 256Kb by default), it relies on system memory mapping
+  facilities, if supported.  (This helps avoid carrying around and
+  possibly fragmenting memory used only for large chunks.)
+
+  All operations (except malloc_stats and mallinfo) have execution
+  times that are bounded by a constant factor of the number of bits in
+  a size_t, not counting any clearing in calloc or copying in realloc,
+  or actions surrounding MORECORE and MMAP that have times
+  proportional to the number of non-contiguous regions returned by
+  system allocation routines, which is often just 1.
+
+  The implementation is not very modular and seriously overuses
+  macros. Perhaps someday all C compilers will do as good a job
+  inlining modular code as can now be done by brute-force expansion,
+  but now, enough of them seem not to.
+
+  Some compilers issue a lot of warnings about code that is
+  dead/unreachable only on some platforms, and also about intentional
+  uses of negation on unsigned types. All known cases of each can be
+  ignored.
+
+  For a longer but out of date high-level description, see
+     http://gee.cs.oswego.edu/dl/html/malloc.html
+
+* MSPACES
+  If MSPACES is defined, then in addition to malloc, free, etc.,
+  this file also defines mspace_malloc, mspace_free, etc. These
+  are versions of malloc routines that take an "mspace" argument
+  obtained using create_mspace, to control all internal bookkeeping.
+  If ONLY_MSPACES is defined, only these versions are compiled.
+  So if you would like to use this allocator for only some allocations,
+  and your system malloc for others, you can compile with
+  ONLY_MSPACES and then do something like...
+    static mspace mymspace = create_mspace(0,0); // for example
+    #define mymalloc(bytes)  mspace_malloc(mymspace, bytes)
+
+  (Note: If you only need one instance of an mspace, you can instead
+  use "USE_DL_PREFIX" to relabel the global malloc.)
+
+  You can similarly create thread-local allocators by storing
+  mspaces as thread-locals. For example:
+    static __thread mspace tlms = 0;
+    void*  tlmalloc(size_t bytes) {
+      if (tlms == 0) tlms = create_mspace(0, 0);
+      return mspace_malloc(tlms, bytes);
+    }
+    void  tlfree(void* mem) { mspace_free(tlms, mem); }
+
+  Unless FOOTERS is defined, each mspace is completely independent.
+  You cannot allocate from one and free to another (although
+  conformance is only weakly checked, so usage errors are not always
+  caught). If FOOTERS is defined, then each chunk carries around a tag
+  indicating its originating mspace, and frees are directed to their
+  originating spaces.
+
+ -------------------------  Compile-time options ---------------------------
+
+Be careful in setting #define values for numerical constants of type
+size_t. On some systems, literal values are not automatically extended
+to size_t precision unless they are explicitly casted.
+
+WIN32                    default: defined if _WIN32 defined
+  Defining WIN32 sets up defaults for MS environment and compilers.
+  Otherwise defaults are for unix.
+
+MALLOC_ALIGNMENT         default: (size_t)8
+  Controls the minimum alignment for malloc'ed chunks.  It must be a
+  power of two and at least 8, even on machines for which smaller
+  alignments would suffice. It may be defined as larger than this
+  though. Note however that code and data structures are optimized for
+  the case of 8-byte alignment.
+
+MSPACES                  default: 0 (false)
+  If true, compile in support for independent allocation spaces.
+  This is only supported if HAVE_MMAP is true.
+
+ONLY_MSPACES             default: 0 (false)
+  If true, only compile in mspace versions, not regular versions.
+
+USE_LOCKS                default: 0 (false)
+  Causes each call to each public routine to be surrounded with
+  pthread or WIN32 mutex lock/unlock. (If set true, this can be
+  overridden on a per-mspace basis for mspace versions.)
+
+FOOTERS                  default: 0
+  If true, provide extra checking and dispatching by placing
+  information in the footers of allocated chunks. This adds
+  space and time overhead.
+
+INSECURE                 default: 0
+  If true, omit checks for usage errors and heap space overwrites.
+
+USE_DL_PREFIX            default: NOT defined
+  Causes compiler to prefix all public routines with the string 'dl'.
+  This can be useful when you only want to use this malloc in one part
+  of a program, using your regular system malloc elsewhere.
+
+ABORT                    default: defined as abort()
+  Defines how to abort on failed checks.  On most systems, a failed
+  check cannot die with an "assert" or even print an informative
+  message, because the underlying print routines in turn call malloc,
+  which will fail again.  Generally, the best policy is to simply call
+  abort(). It's not very useful to do more than this because many
+  errors due to overwriting will show up as address faults (null, odd
+  addresses etc) rather than malloc-triggered checks, so will also
+  abort.  Also, most compilers know that abort() does not return, so
+  can better optimize code conditionally calling it.
+
+PROCEED_ON_ERROR           default: defined as 0 (false)
+  Controls whether detected bad addresses cause them to bypassed
+  rather than aborting. If set, detected bad arguments to free and
+  realloc are ignored. And all bookkeeping information is zeroed out
+  upon a detected overwrite of freed heap space, thus losing the
+  ability to ever return it from malloc again, but enabling the
+  application to proceed. If PROCEED_ON_ERROR is defined, the
+  static variable malloc_corruption_error_count is compiled in
+  and can be examined to see if errors have occurred. This option
+  generates slower code than the default abort policy.
+
+DEBUG                    default: NOT defined
+  The DEBUG setting is mainly intended for people trying to modify
+  this code or diagnose problems when porting to new platforms.
+  However, it may also be able to better isolate user errors than just
+  using runtime checks.  The assertions in the check routines spell
+  out in more detail the assumptions and invariants underlying the
+  algorithms.  The checking is fairly extensive, and will slow down
+  execution noticeably. Calling malloc_stats or mallinfo with DEBUG
+  set will attempt to check every non-mmapped allocated and free chunk
+  in the course of computing the summaries.
+
+ABORT_ON_ASSERT_FAILURE   default: defined as 1 (true)
+  Debugging assertion failures can be nearly impossible if your
+  version of the assert macro causes malloc to be called, which will
+  lead to a cascade of further failures, blowing the runtime stack.
+  ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(),
+  which will usually make debugging easier.
+
+MALLOC_FAILURE_ACTION     default: sets errno to ENOMEM, or no-op on win32
+  The action to take before "return 0" when malloc fails to be able to
+  return memory because there is none available.
+
+HAVE_MORECORE             default: 1 (true) unless win32 or ONLY_MSPACES
+  True if this system supports sbrk or an emulation of it.
+
+MORECORE                  default: sbrk
+  The name of the sbrk-style system routine to call to obtain more
+  memory.  See below for guidance on writing custom MORECORE
+  functions. The type of the argument to sbrk/MORECORE varies across
+  systems.  It cannot be size_t, because it supports negative
+  arguments, so it is normally the signed type of the same width as
+  size_t (sometimes declared as "intptr_t").  It doesn't much matter
+  though. Internally, we only call it with arguments less than half
+  the max value of a size_t, which should work across all reasonable
+  possibilities, although sometimes generating compiler warnings.  See
+  near the end of this file for guidelines for creating a custom
+  version of MORECORE.
+
+MORECORE_CONTIGUOUS       default: 1 (true)
+  If true, take advantage of fact that consecutive calls to MORECORE
+  with positive arguments always return contiguous increasing
+  addresses.  This is true of unix sbrk. It does not hurt too much to
+  set it true anyway, since malloc copes with non-contiguities.
+  Setting it false when definitely non-contiguous saves time
+  and possibly wasted space it would take to discover this though.
+
+MORECORE_CANNOT_TRIM      default: NOT defined
+  True if MORECORE cannot release space back to the system when given
+  negative arguments. This is generally necessary only if you are
+  using a hand-crafted MORECORE function that cannot handle negative
+  arguments.
+
+HAVE_MMAP                 default: 1 (true)
+  True if this system supports mmap or an emulation of it.  If so, and
+  HAVE_MORECORE is not true, MMAP is used for all system
+  allocation. If set and HAVE_MORECORE is true as well, MMAP is
+  primarily used to directly allocate very large blocks. It is also
+  used as a backup strategy in cases where MORECORE fails to provide
+  space from system. Note: A single call to MUNMAP is assumed to be
+  able to unmap memory that may have be allocated using multiple calls
+  to MMAP, so long as they are adjacent.
+
+HAVE_MREMAP               default: 1 on linux, else 0
+  If true realloc() uses mremap() to re-allocate large blocks and
+  extend or shrink allocation spaces.
+
+MMAP_CLEARS               default: 1 on unix
+  True if mmap clears memory so calloc doesn't need to. This is true
+  for standard unix mmap using /dev/zero.
+
+USE_BUILTIN_FFS            default: 0 (i.e., not used)
+  Causes malloc to use the builtin ffs() function to compute indices.
+  Some compilers may recognize and intrinsify ffs to be faster than the
+  supplied C version. Also, the case of x86 using gcc is special-cased
+  to an asm instruction, so is already as fast as it can be, and so
+  this setting has no effect. (On most x86s, the asm version is only
+  slightly faster than the C version.)
+
+malloc_getpagesize         default: derive from system includes, or 4096.
+  The system page size. To the extent possible, this malloc manages
+  memory from the system in page-size units.  This may be (and
+  usually is) a function rather than a constant. This is ignored
+  if WIN32, where page size is determined using getSystemInfo during
+  initialization.
+
+USE_DEV_RANDOM             default: 0 (i.e., not used)
+  Causes malloc to use /dev/random to initialize secure magic seed for
+  stamping footers. Otherwise, the current time is used.
+
+NO_MALLINFO                default: 0
+  If defined, don't compile "mallinfo". This can be a simple way
+  of dealing with mismatches between system declarations and
+  those in this file.
+
+MALLINFO_FIELD_TYPE        default: size_t
+  The type of the fields in the mallinfo struct. This was originally
+  defined as "int" in SVID etc, but is more usefully defined as
+  size_t. The value is used only if  HAVE_USR_INCLUDE_MALLOC_H is not set
+
+REALLOC_ZERO_BYTES_FREES    default: not defined
+  This should be set if a call to realloc with zero bytes should 
+  be the same as a call to free. Some people think it should. Otherwise, 
+  since this malloc returns a unique pointer for malloc(0), so does 
+  realloc(p, 0).
+
+LACKS_UNISTD_H, LACKS_FCNTL_H, LACKS_SYS_PARAM_H, LACKS_SYS_MMAN_H
+LACKS_STRINGS_H, LACKS_STRING_H, LACKS_SYS_TYPES_H,  LACKS_ERRNO_H
+LACKS_STDLIB_H                default: NOT defined unless on WIN32
+  Define these if your system does not have these header files.
+  You might need to manually insert some of the declarations they provide.
+
+DEFAULT_GRANULARITY        default: page size if MORECORE_CONTIGUOUS,
+                                system_info.dwAllocationGranularity in WIN32,
+                                otherwise 64K.
+      Also settable using mallopt(M_GRANULARITY, x)
+  The unit for allocating and deallocating memory from the system.  On
+  most systems with contiguous MORECORE, there is no reason to
+  make this more than a page. However, systems with MMAP tend to
+  either require or encourage larger granularities.  You can increase
+  this value to prevent system allocation functions to be called so
+  often, especially if they are slow.  The value must be at least one
+  page and must be a power of two.  Setting to 0 causes initialization
+  to either page size or win32 region size.  (Note: In previous
+  versions of malloc, the equivalent of this option was called
+  "TOP_PAD")
+
+DEFAULT_TRIM_THRESHOLD    default: 2MB
+      Also settable using mallopt(M_TRIM_THRESHOLD, x)
+  The maximum amount of unused top-most memory to keep before
+  releasing via malloc_trim in free().  Automatic trimming is mainly
+  useful in long-lived programs using contiguous MORECORE.  Because
+  trimming via sbrk can be slow on some systems, and can sometimes be
+  wasteful (in cases where programs immediately afterward allocate
+  more large chunks) the value should be high enough so that your
+  overall system performance would improve by releasing this much
+  memory.  As a rough guide, you might set to a value close to the
+  average size of a process (program) running on your system.
+  Releasing this much memory would allow such a process to run in
+  memory.  Generally, it is worth tuning trim thresholds when a
+  program undergoes phases where several large chunks are allocated
+  and released in ways that can reuse each other's storage, perhaps
+  mixed with phases where there are no such chunks at all. The trim
+  value must be greater than page size to have any useful effect.  To
+  disable trimming completely, you can set to MAX_SIZE_T. Note that the trick
+  some people use of mallocing a huge space and then freeing it at
+  program startup, in an attempt to reserve system memory, doesn't
+  have the intended effect under automatic trimming, since that memory
+  will immediately be returned to the system.
+
+DEFAULT_MMAP_THRESHOLD       default: 256K
+      Also settable using mallopt(M_MMAP_THRESHOLD, x)
+  The request size threshold for using MMAP to directly service a
+  request. Requests of at least this size that cannot be allocated
+  using already-existing space will be serviced via mmap.  (If enough
+  normal freed space already exists it is used instead.)  Using mmap
+  segregates relatively large chunks of memory so that they can be
+  individually obtained and released from the host system. A request
+  serviced through mmap is never reused by any other request (at least
+  not directly; the system may just so happen to remap successive
+  requests to the same locations).  Segregating space in this way has
+  the benefits that: Mmapped space can always be individually released
+  back to the system, which helps keep the system level memory demands
+  of a long-lived program low.  Also, mapped memory doesn't become
+  `locked' between other chunks, as can happen with normally allocated
+  chunks, which means that even trimming via malloc_trim would not
+  release them.  However, it has the disadvantage that the space
+  cannot be reclaimed, consolidated, and then used to service later
+  requests, as happens with normal chunks.  The advantages of mmap
+  nearly always outweigh disadvantages for "large" chunks, but the
+  value of "large" may vary across systems.  The default is an
+  empirically derived value that works well in most systems. You can
+  disable mmap by setting to MAX_SIZE_T.

+  independent elements that can hold contents of size elem_size, each
+  of which starts out cleared, and can be independently freed,
+  realloc'ed etc. The elements are guaranteed to be adjacently
+  allocated (this is not guaranteed to occur with multiple callocs or
+  mallocs), which may also improve cache locality in some
+  applications.
+
+  The "chunks" argument is optional (i.e., may be null, which is
+  probably the most typical usage). If it is null, the returned array
+  is itself dynamically allocated and should also be freed when it is
+  no longer needed. Otherwise, the chunks array must be of at least
+  n_elements in length. It is filled in with the pointers to the
+  chunks.
+
+  In either case, independent_calloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and "chunks"
+  is null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use regular calloc and assign pointers into this
+  space to represent elements.  (In this case though, you cannot
+  independently free elements.)
+
+  independent_calloc simplifies and speeds up implementations of many
+  kinds of pools.  It may also be useful when constructing large data
+  structures that initially have a fixed number of fixed-sized nodes,
+  but the number is not known at compile time, and some of the nodes
+  may later need to be freed. For example:
+
+  struct Node { int item; struct Node* next; };

+  independent_comalloc(size_t n_elements, size_t sizes[], void* chunks[]);
+
+  independent_comalloc allocates, all at once, a set of n_elements
+  chunks with sizes indicated in the "sizes" array.    It returns
+  an array of pointers to these elements, each of which can be
+  independently freed, realloc'ed etc. The elements are guaranteed to
+  be adjacently allocated (this is not guaranteed to occur with
+  multiple callocs or mallocs), which may also improve cache locality
+  in some applications.
+
+  The "chunks" argument is optional (i.e., may be null). If it is null
+  the returned array is itself dynamically allocated and should also
+  be freed when it is no longer needed. Otherwise, the chunks array
+  must be of at least n_elements in length. It is filled in with the
+  pointers to the chunks.
+
+  In either case, independent_comalloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and chunks is
+  null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use a single regular malloc, and assign pointers at
+  particular offsets in the aggregate space. (In this case though, you
+  cannot independently free elements.)
+
+  independent_comallac differs from independent_calloc in that each
+  element may have a different size, and also that it does not
+  automatically clear elements.
+
+  independent_comalloc can be used to speed up allocation in cases
+  where several structs or objects must always be allocated at the
+  same time.  For example:
+
+  struct Head { ... }
+  struct Foot { ... }
+

+
+  In general though, independent_comalloc is worth using only for

+  detect enough difference from series of malloc calls to bother.

+/* -----------------------  Chunk representations ------------------------ */
+
+/*
+  (The following includes lightly edited explanations by Colin Plumb.)
+
+  The malloc_chunk declaration below is misleading (but accurate and
+  necessary).  It declares a "view" into memory allowing access to
+  necessary fields at known offsets from a given base.
+
+  Chunks of memory are maintained using a `boundary tag' method as
+  originally described by Knuth.  (See the paper by Paul Wilson
+  ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such
+  techniques.)  Sizes of free chunks are stored both in the front of
+  each chunk and at the end.  This makes consolidating fragmented
+  chunks into bigger chunks fast.  The head fields also hold bits
+  representing whether chunks are free or in use.
+
+  Here are some pictures to make it clearer.  They are "exploded" to
+  show that the state of a chunk can be thought of as extending from
+  the high 31 bits of the head field of its header through the
+  prev_foot and PINUSE_BIT bit of the following chunk header.
+
+  A chunk that's in use looks like:
+
+   chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+           | Size of previous chunk (if P = 1)                             |

+  Note that since we always merge adjacent free chunks, the chunks
+  adjacent to a free chunk must be in use.
+
+  Given a pointer to a chunk (which can be derived trivially from the
+  payload pointer) we can, in O(1) time, find out whether the adjacent
+  chunks are free, and if so, unlink them from the lists that they
+  are on and merge them with the current chunk.
+
+  Chunks always begin on even word boundaries, so the mem portion
+  (which is returned to the user) is also on an even word boundary, and
+  thus at least double-word aligned.
+
+  The P (PINUSE_BIT) bit, stored in the unused low-order bit of the
+  chunk size (which is always a multiple of two words), is an in-use
+  bit for the *previous* chunk.  If that bit is *clear*, then the
+  word before the current chunk size contains the previous chunk
+  size, and can be used to find the front of the previous chunk.
+  The very first chunk allocated always has this bit set, preventing
+  access to non-existent (or non-owned) memory. If pinuse is set for
+  any given chunk, then you CANNOT determine the size of the
+  previous chunk, and might even get a memory addressing fault when
+  trying to do so.
+
+  The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of
+  the chunk size redundantly records whether the current chunk is
+  inuse. This redundancy enables usage checks within free and realloc,
+  and reduces indirection when freeing and consolidating chunks.
+
+  Each freshly allocated chunk must have both cinuse and pinuse set.
+  That is, each allocated chunk borders either a previously allocated
+  and still in-use chunk, or the base of its memory arena. This is
+  ensured by making all allocations from the the `lowest' part of any
+  found chunk.  Further, no free chunk physically borders another one,
+  so each free chunk is known to be preceded and followed by either
+  inuse chunks or the ends of memory.
+
+  Note that the `foot' of the current chunk is actually represented
+  as the prev_foot of the NEXT chunk. This makes it easier to
+  deal with alignments etc but can be very confusing when trying
+  to extend or adapt this code.
+
+  The exceptions to all this are
+
+     1. The special chunk `top' is the top-most available chunk (i.e.,
+        the one bordering the end of available memory). It is treated
+        specially.  Top is never included in any bin, is used only if
+        no other chunk is available, and is released back to the
+        system if it is very large (see M_TRIM_THRESHOLD).  In effect,
+        the top chunk is treated as larger (and thus less well
+        fitting) than any other available chunk.  The top chunk
+        doesn't update its trailing size field since there is no next
+        contiguous chunk that would have to index off it. However,
+        space is still allocated for it (TOP_FOOT_SIZE) to enable
+        separation or merging when space is extended.
+
+     3. Chunks allocated via mmap, which have the lowest-order bit
+        (IS_MMAPPED_BIT) set in their prev_foot fields, and do not set
+        PINUSE_BIT in their head fields.  Because they are allocated
+        one-by-one, each must carry its own prev_foot field, which is
+        also used to hold the offset this chunk has within its mmapped
+        region, which is needed to preserve alignment. Each mmapped
+        chunk is trailed by the first two fields of a fake next-chunk
+        for sake of usage checks.

+
+  Each tree holding treenodes is a tree of unique chunk sizes.  Chunks
+  of the same size are arranged in a circularly-linked list, with only
+  the oldest chunk (the next to be used, in our FIFO ordering)
+  actually in the tree.  (Tree members are distinguished by a non-null
+  parent pointer.)  If a chunk with the same size an an existing node
+  is inserted, it is linked off the existing node using pointers that
+  work in the same way as fd/bk pointers of small chunks.
+
+  Each tree contains a power of 2 sized range of chunk sizes (the
+  smallest is 0x100 <= x < 0x180), which is is divided in half at each
+  tree level, with the chunks in the smaller half of the range (0x100
+  <= x < 0x140 for the top nose) in the left subtree and the larger
+  half (0x140 <= x < 0x180) in the right subtree.  This is, of course,
+  done by inspecting individual bits.
+
+  Using these rules, each node's left subtree contains all smaller
+  sizes than its right subtree.  However, the node at the root of each
+  subtree has no particular ordering relationship to either.  (The
+  dividing line between the subtree sizes is based on trie relation.)
+  If we remove the last chunk of a given size from the interior of the
+  tree, we need to replace it with a leaf node.  The tree ordering
+  rules permit a node to be replaced by any leaf below it.
+
+  The smallest chunk in a tree (a common operation in a best-fit
+  allocator) can be found by walking a path to the leftmost leaf in
+  the tree.  Unlike a usual binary tree, where we follow left child
+  pointers until we reach a null, here we follow the right child
+  pointer any time the left one is null, until we reach a leaf with
+  both child pointers null. The smallest chunk in the tree will be
+  somewhere along that path.
+
+  The worst case number of steps to add, find, or remove a node is
+  bounded by the number of bits differentiating chunks within
+  bins. Under current bin calculations, this ranges from 6 up to 21
+  (for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case
+  is of course much better.

+/* ----------------------------- Segments -------------------------------- */
+
+/*
+  Each malloc space may include non-contiguous segments, held in a
+  list headed by an embedded malloc_segment record representing the
+  top-most space. Segments also include flags holding properties of
+  the space. Large chunks that are directly allocated by mmap are not
+  included in this list. They are instead independently created and
+  destroyed without otherwise keeping track of them.
+
+  Segment management mainly comes into play for spaces allocated by
+  MMAP.  Any call to MMAP might or might not return memory that is
+  adjacent to an existing segment.  MORECORE normally contiguously
+  extends the current space, so this space is almost always adjacent,
+  which is simpler and faster to deal with. (This is why MORECORE is
+  used preferentially to MMAP when both are available -- see
+  sys_alloc.)  When allocating using MMAP, we don't use any of the
+  hinting mechanisms (inconsistently) supported in various
+  implementations of unix mmap, or distinguish reserving from
+  committing memory. Instead, we just ask for space, and exploit
+  contiguity when we get it.  It is probably possible to do
+  better than this on some systems, but no general scheme seems
+  to be significantly better.
+
+  Management entails a simpler variant of the consolidation scheme
+  used for chunks to reduce fragmentation -- new adjacent memory is
+  normally prepended or appended to an existing segment. However,
+  there are limitations compared to chunk consolidation that mostly
+  reflect the fact that segment processing is relatively infrequent
+  (occurring only when getting memory from system) and that we
+  don't expect to have huge numbers of segments:
+
+  * Segments are not indexed, so traversal requires linear scans.  (It
+    would be possible to index these, but is not worth the extra
+    overhead and complexity for most programs on most platforms.)
+  * New segments are only appended to old ones when holding top-most
+    memory; if they cannot be prepended to others, they are held in
+    different segments.
+
+  Except for the top-most segment of an mstate, each segment record
+  is kept at the tail of its segment. Segments are added by pushing
+  segment records onto the list headed by &mstate.seg for the
+  containing mstate.
+
+  Segment flags control allocation/merge/deallocation policies:
+  * If EXTERN_BIT set, then we did not allocate this segment,
+    and so should not try to deallocate or merge with others.
+    (This currently holds only for the initial segment passed
+    into create_mspace_with_base.)
+  * If IS_MMAPPED_BIT set, the segment may be merged with
+    other surrounding mmapped segments and trimmed/de-allocated
+    using munmap.
+  * If neither bit is set, then the segment was obtained using
+    MORECORE so can be merged with surrounding MORECORE'd segments
+    and deallocated/trimmed using MORECORE with negative arguments.

+   A malloc_state holds all of the bookkeeping for a space.
+   The main fields are:
+
+  Top
+    The topmost chunk of the currently active segment. Its size is
+    cached in topsize.  The actual size of topmost space is
+    topsize+TOP_FOOT_SIZE, which includes space reserved for adding

+    space from the system.  The size at which to autotrim top is
+    cached from mparams in trim_check, except that it is disabled if
+    an autotrim fails.
+
+  Designated victim (dv)
+    This is the preferred chunk for servicing small requests that
+    don't have exact fits.  It is normally the chunk split off most
+    recently to service another small request.  Its size is cached in
+    dvsize. The link fields of this chunk are not maintained since it
+    is not kept in a bin.
+
+  SmallBins
+    An array of bin headers for free chunks.  These bins hold chunks
+    with sizes less than MIN_LARGE_SIZE bytes. Each bin contains
+    chunks of all the same size, spaced 8 bytes apart.  To simplify
+    use in double-linked lists, each bin header acts as a malloc_chunk
+    pointing to the real first node, if it exists (else pointing to
+    itself).  This avoids special-casing for headers.  But to avoid
+    waste, we allocate only the fd/bk pointers of bins, and then use
+    repositioning tricks to treat these as the fields of a chunk.
+
+  TreeBins
+    Treebins are pointers to the roots of trees holding a range of
+    sizes. There are 2 equally spaced treebins for each power of two
+    from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything
+    larger.
+
+  Bin maps
+    There is one bit map for small bins ("smallmap") and one for
+    treebins ("treemap).  Each bin sets its bit when non-empty, and
+    clears the bit when empty.  Bit operations are then used to avoid
+    bin-by-bin searching -- nearly all "search" is done without ever
+    looking at bins that won't be selected.  The bit maps
+    conservatively use 32 bits per map word, even if on 64bit system.
+    For a good description of some of the bit-based techniques used
+    here, see Henry S. Warren Jr's book "Hacker's Delight" (and
+    supplement at http://hackersdelight.org/). Many of these are
+    intended to reduce the branchiness of paths through malloc etc, as
+    well as to reduce the number of memory locations read or written.
+
+  Segments
+    A list of segments headed by an embedded malloc_segment record
+    representing the initial space.
+
+  Address check support
+    The least_addr field is the least address ever obtained from
+    MORECORE or MMAP. Attempted frees and reallocs of any address less
+    than this are trapped (unless INSECURE is defined).
+
+  Magic tag
+    A cross-check field that should always hold same value as mparams.magic.
+
+  Flags
+    Bits recording whether to use MMAP, locks, or contiguous MORECORE
+
+  Statistics
+    Each space keeps track of current and maximum system memory
+    obtained via MORECORE or MMAP.
+
+  Locking
+    If USE_LOCKS is defined, the "mutex" lock is acquired and released
+    around every public call using this mspace.

+  For security, the main invariant is that malloc/free/etc never
+  writes to a static address other than malloc_state, unless static
+  malloc_state itself has been corrupted, which cannot occur via
+  malloc (because of these checks). In essence this means that we
+  believe all pointers, sizes, maps etc held in malloc_state, but
+  check all of those linked or offsetted from other embedded data
+  structures.  These checks are interspersed with main code in a way
+  that tends to minimize their run-time cost.
+
+  When FOOTERS is defined, in addition to range checking, we also
+  verify footer fields of inuse chunks, which can be used guarantee
+  that the mstate controlling malloc/free is intact.  This is a
+  streamlined version of the approach described by William Robertson
+  et al in "Run-time Detection of Heap-based Overflows" LISA'03
+  http://www.usenix.org/events/lisa03/tech/robertson.html The footer
+  of an inuse chunk holds the xor of its mstate and a random seed,
+  that is checked upon calls to free() and realloc().  This is
+  (probablistically) unguessable from outside the program, but can be
+  computed by any code successfully malloc'ing any chunk, so does not
+  itself provide protection against code that has already broken
+  security through some other means.  Unlike Robertson et al, we
+  always dynamically check addresses of all offset chunks (previous,
+  next, etc). This turns out to be cheaper than relying on hashes.

+/* -------------------- Alternative MORECORE functions ------------------- */
+
+/*
+  Guidelines for creating a custom version of MORECORE:
+
+  * For best performance, MORECORE should allocate in multiples of pagesize.
+  * MORECORE may allocate more memory than requested. (Or even less,
+      but this will usually result in a malloc failure.)
+  * MORECORE must not allocate memory when given argument zero, but
+      instead return one past the end address of memory from previous
+      nonzero call.
+  * For best performance, consecutive calls to MORECORE with positive
+      arguments should return increasing addresses, indicating that
+      space has been contiguously extended.
+  * Even though consecutive calls to MORECORE need not return contiguous
+      addresses, it must be OK for malloc'ed chunks to span multiple
+      regions in those cases where they do happen to be contiguous.
+  * MORECORE need not handle negative arguments -- it may instead
+      just return MFAIL when given negative arguments.
+      Negative arguments are always multiples of pagesize. MORECORE
+      must not misinterpret negative args as large positive unsigned
+      args. You can suppress all such calls from even occurring by defining
+      MORECORE_CANNOT_TRIM,
+
+  As an example alternative MORECORE, here is a custom allocator
+  kindly contributed for pre-OSX macOS.  It uses virtually but not
+  necessarily physically contiguous non-paged memory (locked in,
+  present and won't get swapped out).  You can use it by uncommenting
+  this section, adding some #includes, and setting up the appropriate
+  defines above:
+
+      #define MORECORE osMoreCore
+
+  There is also a shutdown routine that should somehow be called for
+  cleanup upon program exit.
+
+  #define MAX_POOL_ENTRIES 100
+  #define MINIMUM_MORECORE_SIZE  (64 * 1024U)

+         ptr = PoolAllocateResident(size + RM_PAGE_SIZE, 0);

+        given above changes.

+  independent_calloc(size_t n_elements, size_t element_size, void* chunks[]);
+
+  independent_calloc is similar to calloc, but instead of returning a
+  single cleared space, it returns an array of pointers to n_elements
+  independent elements that can hold contents of size elem_size, each
+  of which starts out cleared, and can be independently freed,
+  realloc'ed etc. The elements are guaranteed to be adjacently
+  allocated (this is not guaranteed to occur with multiple callocs or
+  mallocs), which may also improve cache locality in some
+  applications.
+
+  The "chunks" argument is optional (i.e., may be null, which is
+  probably the most typical usage). If it is null, the returned array
+  is itself dynamically allocated and should also be freed when it is
+  no longer needed. Otherwise, the chunks array must be of at least
+  n_elements in length. It is filled in with the pointers to the
+  chunks.
+
+  In either case, independent_calloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and "chunks"
+  is null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use regular calloc and assign pointers into this
+  space to represent elements.  (In this case though, you cannot
+  independently free elements.)
+
+  independent_calloc simplifies and speeds up implementations of many
+  kinds of pools.  It may also be useful when constructing large data
+  structures that initially have a fixed number of fixed-sized nodes,
+  but the number is not known at compile time, and some of the nodes
+  may later need to be freed. For example:
+
+  struct Node { int item; struct Node* next; };
+
+  struct Node* build_list() {
+    struct Node** pool;
+    int n = read_number_of_nodes_needed();
+    if (n <= 0) return 0;
+    pool = (struct Node**)(independent_calloc(n, sizeof(struct Node), 0);
+    if (pool == 0) die();
+    // organize into a linked list...

+
+  independent_comalloc allocates, all at once, a set of n_elements
+  chunks with sizes indicated in the "sizes" array.    It returns
+  an array of pointers to these elements, each of which can be
+  independently freed, realloc'ed etc. The elements are guaranteed to
+  be adjacently allocated (this is not guaranteed to occur with
+  multiple callocs or mallocs), which may also improve cache locality
+  in some applications.
+
+  The "chunks" argument is optional (i.e., may be null). If it is null
+  the returned array is itself dynamically allocated and should also
+  be freed when it is no longer needed. Otherwise, the chunks array
+  must be of at least n_elements in length. It is filled in with the
+  pointers to the chunks.
+
+  In either case, independent_comalloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and chunks is
+  null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use a single regular malloc, and assign pointers at
+  particular offsets in the aggregate space. (In this case though, you
+  cannot independently free elements.)
+
+  independent_comallac differs from independent_calloc in that each
+  element may have a different size, and also that it does not
+  automatically clear elements.
+
+  independent_comalloc can be used to speed up allocation in cases
+  where several structs or objects must always be allocated at the
+  same time.  For example:
+
+  struct Head { ... }
+  struct Foot { ... }
+
+  void send_message(char* msg) {
+    int msglen = strlen(msg);
+    size_t sizes[3] = { sizeof(struct Head), msglen, sizeof(struct Foot) };
+    void* chunks[3];
+    if (independent_comalloc(3, sizes, chunks) == 0)
+      die();
+    struct Head* head = (struct Head*)(chunks[0]);
+    char*        body = (char*)(chunks[1]);
+    struct Foot* foot = (struct Foot*)(chunks[2]);
+    // ...
+  }
+
+  In general though, independent_comalloc is worth using only for
+  larger values of n_elements. For small values, you probably won't
+  detect enough difference from series of malloc calls to bother.
+
+  Overuse of independent_comalloc can increase overall memory usage,
+  since it cannot reuse existing noncontiguous small chunks that
+  might be available for some of the elements.

+Bionic C Library Overview:
+==========================
+
+Introduction:
+
+Core Philosophy:
+
+  The core idea behind Bionic's design is: KEEP IT REALLY SIMPLE.
+
+  This implies that the C library should only provide lightweight wrappers
+  around kernel facilities and not try to be too smart to deal with edge cases.
+
+  The name "Bionic" comes from the fact that it is part-BSD and part-Linux:
+  its source code consists in a mix of BSD C library pieces with custom
+  Linux-specific bits used to deal with threads, processes, signals and a few
+  others things.
+
+  All original BSD pieces carry the BSD copyright disclaimer. Bionic-specific 
+  bits carry the Android Open Source Project copyright disclaimer. And
+  everything is released under the BSD license.
+
+Architectures:
+
+  Bionic currently supports the ARM and x86 instruction sets. In theory, it
+  should be possible to support more, but this may require a little work (e.g.
+  adding system call IDs to SYSCALLS.TXT, described below, or modifying the
+  dynamic linker).
+
+  The ARM-specific code is under arch-arm/ and the x86-specific one is under
+  arch-x86/
+
+  Note that the x86 version is only meant to run on an x86 Android device. We
+  make absolutely no claim that you could build and use Bionic on a stock x86
+  Linux distribution (though that would be cool, so patches are welcomed :-))
+
+Syscall stubs:
+
+  Each system call function is implemented by a tiny assembler source fragment
+  (called a "syscall stub"), which is generated automatically by
+  tools/gensyscalls.py which reads the SYSCALLS.TXT file for input.
+
+  SYSCALLS.TXT contains the list of all syscall stubs to generate, along with
+  the corresponding syscall numeric identifier (which may differ between ARM
+  and x86), and its signature
+
+  If you modify this file, you may want to use tools/checksyscalls.py which
+  checks its content against official Linux kernel header files, and will
+  report errors when invalid syscall ids are used.
+
+  Sometimes, the C library function is really a wrapper that calls the
+  corresponding syscall with another name. For example, the exit() function
+  is provided by the C library and calls the _exit() syscall stub.
+
+  See SYSCALLS.TXT for documentation and details.
+
+
+time_t:
+
+  time_t is 32-bit as defined by the kernel on 32-bit CPUs. A 64-bit version
+  would be preferrable to avoid the Y2038 bug, but the kernel maintainers
+  consider that this is not needed at the moment.
+
+  Instead, Bionic provides a <time64.h> header that defines a time64_t type,
+  and related functions like mktime64(), localtime64(), etc...
+
+
+Timezone management:
+
+  The name of the current timezone is taken from the TZ environment variable,
+  if defined. Otherwise, the system property named 'persist.sys.timezone' is
+  checked instead.
+
+  The zoneinfo timezone database and index files are located under directory
+  /system/usr/share/zoneinfo, instead of the more Posix-compliant path of
+  /usr/share/zoneinfo
+
+
+off_t:
+
+  For similar reasons, off_t is 32-bit. We define loff_t as the 64-bit variant
+  due to BSD inheritance, but off64_t should be available as a typedef to ease
+  porting of current Linux-specific code.
+
+
+Linux kernel headers:
+
+  Bionic comes with its own set of "clean" Linux kernel headers to allow
+  user-space code to use kernel-specific declarations (e.g. IOCTLs, structure
+  declarations, constants, etc...). They are located in:
+
+     ./kernel/common,
+     ./kernel/arch-arm
+     ./kernel/arch-x86
+
+  These headers have been generated by a tool (kernel/tools/update-all.py) to
+  only include the public definitions from the original Linux kernel headers.
+
+  If you want to know why and how this is done, read kernel/README.TXT to get
+  all the (gory) details.
+
+
+PThread implementation:
+
+   Bionic's C library comes with its own pthread implementation bundled in.
+   This is different from other historical C libraries which:
+
+    - place it in an external library (-lpthread)
+    - play linker tricks with weak symbols at dynamic link time
+
+   The support for real-time features (a.k.a. -lrt) is also bundled in the
+   C library.
+
+   The implementation is based on futexes and strives to provide *very* short
+   code paths for common operations. Notable features are the following:
+
+      - pthread_mutex_t, pthread_cond_t are only 4 bytes each.
+
+      - Normal, recursive and error-check mutexes are supported, and the code
+        path is heavily optimized for the normal case, which is used most of
+        the time.
+
+      - Process-shared mutexes and condition variables are not supported.
+        Their implementation requires far more complexity and was absolutely
+        not needed for Android (which uses other inter-process synchronization
+        capabilities).
+
+        Note that they could be added in the future without breaking the ABI
+        by specifying more sophisticated code paths (which may make the common
+        paths slightly slower though).
+
+      - There is currently no support for read/write locks, priority-ceiling in
+        mutexes and other more advanced features. Again, the main idea being
+        that this was not needed for Android at all but could be added in the
+        future.
+
+pthread_cancel():
+
+   pthread_cancel() will *not* be supported in Bionic, because doing this would
+   involve making the C library significantly bigger for very little benefit.
+
+   Consider that:
+
+     - A proper implementation must insert pthread cancellation checks in a lot
+       of different places of the C library. And conformance is very difficult
+       to test properly.
+
+     - A proper implementation must also clean up resources, like releasing
+       memory, or unlocking mutexes, properly if the cancellation happens in a
+       complex function (e.g. inside gethostbyname() or fprintf() + complex
+       formatting rules). This tends to slow down the path of many functions.
+
+     - pthread cancellation cannot stop all threads: e.g. it can't do anything
+       against an infinite loop
+
+     - pthread cancellation itself has short-comings and isn't very portable
+       (see http://advogato.org/person/slamb/diary.html?start=49 for example).
+
+   All of this is contrary to the Bionic design goals. If your code depends on
+   thread cancellation, please consider alternatives.
+
+   Note however that Bionic does implement pthread_cleanup_push() and
+   pthread_cleanup_pop(), which can be used to handle cleanups that happen when
+   a thread voluntarily exits through pthread_exit() or returning from its
+   main function.
+
+
+pthread_once():
+
+  Do not call fork() within a callback provided to pthread_once(). Doing this
+  may result in a deadlock in the child process the next time it calls
+  pthread_once().
+
+  Also, you can't throw a C++ Exception from the callback (see C++ Exception
+  Support below).
+
+  The current implementation of pthread_once() lacks the necessary support of
+  multi-core-safe double-checked-locking (read and write barriers).
+
+
+Thread-specific data
+
+  The thread-specific storage only provides for a bit less than 64
+  pthread_key_t objects to each process. The implementation provides 64 real
+  slots but also uses about 5 of them (exact number may depend on
+  implementation) for its own use (e.g. two slots are pre-allocated by the C
+  library to speed-up the Android OpenGL sub-system).
+
+  Note that Posix mandates a minimum of 128 slots, but we do not claim to be
+  Posix-compliant.
+
+  Except for the main thread, the TLS area is stored at the top of the stack.
+  See comments in bionic/libc/bionic/pthread.c for details.
+
+  At the moment, thread-local storage defined through the __thread compiler
+  keyword is not supported by the Bionic C library and dynamic linker.
+
+
+Multi-core support
+
+  At the moment, Bionic does not provide or use read/write memory barriers.
+  This means that using it on certain multi-core systems might not be
+  supported, depending on its exact CPU architecture.
+
+
+Android-specific features:
+
+  Bionic provides a small number of Android-specific features to its clients:
+
+  - access to system properties:
+
+       Android provides a simple shared value/key space to all processes on the
+       system. It stores a liberal number of 'properties', each of them being a
+       simple size-limited string that can be associated to a size-limited
+       string value.
+
+       The header <sys/system_properties.h> can be used to read system
+       properties and also defines the maximum size of keys and values.
+
+   - Android-specific user/group management:
+
+       There is no /etc/passwd or /etc/groups in Android. By design, it is
+       meant to be used by a single handset user. On the other hand, Android
+       uses the Linux user/group management features extensively to secure
+       process permissions, like access to various filesystem directories.
+
+       In the Android scheme, each installed application gets its own
+       uid_t/gid_t starting from 10000; lower numerical ids are reserved for
+       system daemons.
+
+       getpwnam() recognizes some hard-coded subsystems names (e.g. "radio")
+       and will translate them to their low-user-id values. It also recognizes
+       "app_1234" as the synthetic name of the application that was installed
+       with uid 10000 + 1234, which is 11234. getgrnam() works similarly
+
+       getgrouplist() will always return a single group for any user name,
+       which is the one passed as an input parameter.
+
+       getgrgid() will similarly only return a structure that contains a
+       single-element members list, corresponding to the user with the same
+       numerical value than the group.
+
+       See bionic/libc/bionic/stubs.c for more details.
+
+    - getservent()
+
+       There is no /etc/services on Android. Instead the C library embeds a
+       constant list of services in its executable, which is parsed on demand
+       by the various functions that depend on it. See
+       bionic/libc/netbsd/net/getservent.c and
+       bionic/libc/netbsd/net/services.h
+
+       The list of services defined internally might change liberally in the
+       future. This feature is mostly historically and is very rarely used.
+
+       The getservent() returns thread-local data. getservbyport() and
+       getservbyname() are also implemented in a similar fashion.
+
+     - getprotoent()
+
+       There is no /etc/protocol on Android. Bionic does not currently
+       implement getprotoent() and related functions. If added, it will
+       likely be done in a way similar to getservent()
+
+DNS resolver:
+
+  Bionic uses a NetBSD-derived resolver library which has been modified in
+  the following ways:
+
+     - don't implement the name-server-switch feature (a.k.a. <nsswitch.h>)
+
+     - read /system/etc/resolv.conf instead of /etc/resolv.conf
+
+     - read the list of servers from system properties. the code looks for
+       'net.dns1', 'net.dns2', etc.. Each property should contain the IP
+       address of a DNS server.
+
+       these properties are set/modified by other parts of the Android system
+       (e.g. the dhcpd daemon).
+
+       the implementation also supports per-process DNS server list, using the
+       properties 'net.dns1.<pid>', 'net.dns2.<pid>', etc... Where <pid> stands
+       for the numerical ID of the current process.
+
+     - when performing a query, use a properly randomized Query ID (instead of
+       a incremented one), for increased security.
+
+     - when performing a query, bind the local client socket to a random port
+       for increased security.
+
+     - get rid of *many* unfortunate thread-safety issues in the original code
+
+  Bionic does *not* expose implementation details of its DNS resolver; the
+  content of <arpa/nameser.h> is intentionally blank. The resolver
+  implementation might change completely in the future.
+
+
+PThread Real-Time Timers:
+
+  timer_create(), timer_gettime(), timer_settime() and timer_getoverrun() are
+  supported.
+
+  Bionic also now supports SIGEV_THREAD real-time timers (see timer_create()).
+  The implementation simply uses a single thread per timer, unlike GLibc which
+  uses complex heuristics to try to use the less threads possible when several
+  timers with compatible properties are used.
+
+  This means that if your code uses a lot of SIGEV_THREAD timers, your program
+  may consume a lot of memory. However, if your program needs many of these
+  timers, it'd better handle timeout events directly instead.
+
+  Other timers (e.g. SIGEV_SIGNAL) are handled by the kernel and use much less
+  system resources.
+
+
+Binary Compatibility:
+
+  Bionic is *not* in any way binary-compatible with the GNU C Library, ucLibc
+  or any known Linux C library. This means several things:
+
+  - You cannot expect to build something against the GNU C Library headers and
+    have it dynamically link properly to Bionic later.
+
+  - You should *really* use the Android toolchain to build your program against
+    Bionic. The toolchain deals with many important details that are crucial
+    to get something working properly.
+
+  Failure to do so will usually result in the inability to run or link your
+  program, or even runtime crashes. Several random web pages on the Internet
+  describe how you can succesfully write a "hello-world" program with the
+  ARM GNU toolchain. These examples usually work by chance, if anything else,
+  and you should not follow these instructions unless you want to waste a lot
+  of your time in the process.
+
+  Note however that you *can* generate a binary that is built against the
+  GNU C Library headers and then statically linked to it. The corresponding
+  executable should be able to run (if it doesn't use dlopen()/dlsym())
+
+
+Dynamic Linker:
+
+  Bionic comes with its own dynamic linker (just like ld.so on Linux really
+  comes from GLibc). This linker does not support all the relocations
+  generated by other GCC ARM toolchains.
+
+
+C++ Exceptions Support:
+
+  At the moment, Bionic doesn't support C++ exceptions, what this really means
+  is the following:
+
+    - If pthread_once() is called with a C++ callback that throws an exception,
+      then the C library will keep the corresponding pthread_once_t mutex
+      locked. Any further call to pthread_once() will result in a deadlock.
+
+      A proper implementation should be able to register a C++ exception
+      cleanup handler before the callback to properly unlock the
+      pthread_once_t. Unfortunately this requires tricky assembly code that
+      is highly dependent on the compiler.
+
+      This feature is not planned to be supported anytime soon.
+
+    - The same problem may arise if you throw an exception within a callback
+      called from the C library. Fortunately, these cases are very rare in the
+      real-world, but any callback you provide to the C library should *not*
+      throw an exception.
+
+    - Bionic lacks a few support functions to have exception support work
+      properly.
+
+System V IPCs:
+
+  Bionic intentionally does not provide support for System-V IPCs mechanisms,
+  like the ones provided by semget(), shmget(), msgget(). The reason for this
+  is to avoid denial-of-service. For a detailed rationale about this, please
+  read the file docs/SYSV-IPCS.TXT.
+
+Include Paths:
+
+  The Android build system should automatically provide the necessary include
+  paths required to build against the C library headers. However, if you want
+  to do that yourself, you will need to add:
+
+      libc/arch-$ARCH/include
+      libc/include
+      libc/kernel/common
+      libc/kernel/arch-$ARCH
+
+  to your C include path.

+Android does not support System V IPCs, i.e. the facilities provided by the
+following standard Posix headers:
+
+  <sys/sem.h>   /* SysV semaphores */
+  <sys/shm.h>   /* SysV shared memory segments */
+  <sys/msg.h>   /* SysV message queues */
+  <sys/ipc.h>   /* General IPC definitions */
+
+The reason for this is due to the fact that, by design, they lead to global
+kernel resource leakage.
+
+For example, there is no way to automatically release a SysV semaphore
+allocated in the kernel when:
+
+- a buggy or malicious process exits
+- a non-buggy and non-malicious process crashes or is explicitely killed.
+
+Killing processes automatically to make room for new ones is an
+important part of Android's application lifecycle implementation. This means
+that, even assuming only non-buggy and non-malicious code, it is very likely
+that over time, the kernel global tables used to implement SysV IPCs will fill
+up.
+
+At that point, strange failures are likely to occur and prevent programs that
+use them to run properly until the next reboot of the system.
+
+And we can't ignore potential malicious applications. As a proof of concept
+here is a simple exploit that you can run on a standard Linux box today:

+            }
+        }

+If you run it on a typical Linux distribution today, you'll discover that it
+will quickly fill up the kernel's table of unique key_t values, and that
+strange things will happen in some parts of the system, but not all.
+
+(You can use the "ipcs -u" command to get a summary describing the kernel
+ tables and their allocations)
+
+For example, in our experience, anything program launched after that that
+calls strerror() will simply crash. The USB sub-system starts spoutting weird
+errors to the system console, etc...

+ * literal containing a conversion specifier, possibly modified by
+ * a prefix such as hh, h, l, or ll, suitable for use within the
+ * format argument of a formatted input/output function when

+ * fprintf family) or SCN (character string literals for the fscanf
+ * family), followed by the conversion specifier, followed by a
+ * name corresponding to a similar typedef name.  For example,
+ * PRIdFAST32 can be used in a format string to print the value of
+ * an integer of type int_fast32_t.

+ *
+ *	__link_set_decl(set, ptype)

+ *		macro must be used by any code which wishes to reference
+ *		the elements of a link set.
+ *
+ *	__link_set_start(set)
+ *		This points to the first slot in the link set.
+ *
+ *	__link_set_end(set)
+ *		This points to the (non-existent) slot after the last
+ *		entry in the link set.
+ *
+ *	__link_set_count(set)

+ *
+ * In addition, we provide the following macros for accessing link sets:
+ *
+ *	__link_set_foreach(pvar, set)
+ *		Iterate over the link set `set'.  Because a link set is

+Bionic comes with a set of 'clean' Linux kernel headers that can safely be
+included by userland applications and libraries without fear of hideous
+conflicts. for more information why this is needed, see the "RATIONALE"
+section at the end of this document.
+
+these clean headers are automatically generated by several scripts located
+in the 'bionic/kernel/tools' directory, which process a set of original
+and unmodified kernel headers in order to get rid of many annoying
+declarations and constructs that usually result in compilation failure.
+
+the 'clean headers' only contain type and macro definitions, with the
+exception of a couple static inline functions used for performance
+reason (e.g. optimized CPU-specific byte-swapping routines)
+
+they can be included from C++, or when compiling code in strict ANSI mode.
+they can be also included before or after any Bionic C library header.
+
+the generation process works as follows:
+
+  * 'bionic/kernel/original/'
+    contains a set of kernel headers as normally found in the 'include'
+    directory of a normal Linux kernel source tree. note that this should
+    only contain the files that are really needed by Android (use
+    'find_headers.py' to find these automatically).
+
+  * 'bionic/kernel/common'
+    contains the non-arch-specific clean headers and directories
+    (e.g. linux, asm-generic and mtd)
+
+  *'bionic/kernel/arch-arm/'
+    contains the ARM-specific directory tree of clean headers.
+
+  * 'bionic/kernel/arch-arm/asm'
+    contains the real ARM-specific headers
+
+  * 'bionic/kernel/arch-x86'
+    similarly contains all headers and symlinks to be used on x86
+
+  * 'bionic/kernel/tools' contains various Python and shell scripts used
+    to manage and re-generate the headers
+
+the tools you can use are:
+
+  * tools/find_users.py
+    scans a list of source files or directories and prints which ones do
+    include Linux headers.
+
+  * tools/find_headers.py
+    scans a list of source files or directories and recursively finds all
+    the original kernel headers they need.
+
+  * tools/clean_header.py
+    prints the clean version of a given kernel header. with the -u option,
+    this will also update the corresponding clean header file if its
+    content has changed. you can also process more than one file with -u
+
+  * tools/update_all.py
+    automatically update all clean headers from the content of 
+    'bionic/kernel/original'. this is the script you're likely going to 
+    run whenever you update the original headers.
+
+NOTE:
+  if ANDROID_PRODUCT_OUT is defined in your environment, both 'clean_header.py'
+  and 'update_all.py' will automatically issue "p4 add/edit/delete" commands
+  appropriately to reflect the changes being made.
+
+  you will need to "p4 submit" manually though...
+
+
+HOW TO BUILD BIONIC AND OTHER PROGRAMS WITH THE CLEAN HEADERS:
+==============================================================
+
+add bionic/kernel/common and bionic/kernel/arch-<yourarch> to your C
+include path. that should be enough. Note that Bionic will not compile properly 
+if you don't.
+
+
+HOW TO SUPPORT ANOTHER ARCHITECTURE:
+====================================
+
+see the content of tools/defaults.py, you will need to make a few updates
+here:
+
+  - add a new item to the 'kernel_archs' list of supported architectures
+
+  - add a proper definition for 'kernel_known_<arch>_statics' with
+    relevant definitions.
+
+  - update 'kernel_known_statics' to map "<arch>" to
+    'kernel_known_<arch>_statics'
+
+then, add the new architecture-specific headers to original/asm-<arch>.
+(please ensure that these are really needed, e.g. with tools/find_headers.py)
+
+finally, run tools/update_all.py
+
+
+
+HOW TO UPDATE THE HEADERS WHEN NEEDED:
+======================================
+
+IMPORTANT IMPORTANT:
+
+  WHEN UPDATING THE HEADERS, ALWAYS CHECK THAT THE NEW CLEAN HEADERS DO
+  NOT BREAK THE KERNEL <-> USER ABI, FOR EXAMPLE BY CHANGING THE SIZE
+  OF A GIVEN TYPE. THIS TASK CANNOT BE EASILY AUTOMATED AT THE MOMENT
+
+copy any updated kernel header into the corresponding location under
+'bionic/kernel/original'.
+
+for any new kernel header you want to add, first run tools/find_headers.py to be
+sure that it is really needed by the Android sources. then add it to
+'bionic/kernel/original'
+
+then, run tools/update_all.py to re-run the auto-cleaning
+
+
+
+HOW THE CLEANUP PROCESS WORKS:
+==============================
+
+this section describes the action performed by the cleanup program(s) when they
+process the original kernel headers into clean ones:
+
+1. Optimize well-known macros (e.g. __KERNEL__, __KERNEL_STRICT_NAMES)
+
+    this pass gets rid of everything that is guarded by a well-known macro
+    definition. this means that a block like
+
+       #ifdef __KERNEL__
+       ....
+       #endif
+
+    will be totally omitted from the output. the optimizer is smart enough to
+    handle all complex C-preprocessor conditional expression appropriately.
+    this means that, for example:
+
+       #if defined(__KERNEL__) || defined(FOO)
+       ...
+       #endif
+
+    will be transformed into:
+
+       #ifdef FOO
+       ...
+       #endif
+
+    see tools/defaults.py for the list of well-known macros used in this pass,
+    in case you need to update it in the future.
+
+    note that this also remove any reference to a kernel-specific configuration
+    macro like CONFIG_FOO from the clean headers.
+
+
+2. remove variable and function declarations:
+
+  this pass scans non-directive text and only keeps things that look like a
+  typedef/struct/union/enum declaration. this allows to get rid of any variable
+  or function declaration that should only be used within the kernel anyway
+  (and which normally *should* be guarded in a #ifdef __KERNEL__ ... #endif
+  block, if the kernel writers were not so messy)
+
+  there are however a few exceptions: it is seldom useful to keep the definition
+  of some static inline functions performing very simple operations. a good
+  example is the optimized 32-bit byte-swap function found in
+  arch-arm/asm/byteorder.h
+
+  the list of exceptions is in tools/defaults.py in case you need to update it
+  in the future.
+
+  note that we do *not* remove macro definitions, including these macro that
+  perform a call to one of these kernel-header functions, or even define other
+  functions. we consider it safe since userland applications have no business
+  using them anyway.
+
+
+3. whitespace cleanup:
+
+  the final pass remove any comments and empty lines from the final headers.
+
+
+4. add a standard disclaimer:
+
+  prepended to each generated header, contains a message like
+  "do not edit directly - file was auto-generated by ...."
+
+
+RATIONALE:
+==========
+
+OVERVIEW OF THE CURRENT KERNEL HEADER MESS:
+-------------------------------------------
+
+The original kernel headers are not easily usable from userland applications.
+they contain many declarations and construct that will result in a compilation
+failure or even worse, incorrect behaviour. for example:
+
+- some headers try to define Posix types (e.g. size_t, ssize_t) that can
+  conflict with the corresponding definitions provided by your C library.
+
+- some headers use constructs that cannot be compiled in ANSI C mode.
+
+- some headers use constructs do not compile with C++ at all.
+
+- some headers contain invalid "legacy" definitions for the benefit of old
+  C libraries (e.g. glibc5) but result in incorrect behaviour if used
+  directly.
+
+  e.g. gid_t being defined in <linux/types.h> as a 16-bit type while the
+  kernel uses 32-bit ids. this results in problems when getgroups() or
+  setgroups() are called, since they operate on gid_t arrays.
+
+unfortunately, these headers are also the only source of some really extensive
+constant and type definitions that are required by userland applications.
+think any library/program that need to access ALSA, or Video4Linux, or
+anything related to a specific device or Linux-specific system interface
+(e.g. IOCTLS, etc...)
+
+As a consequence, every Linux distribution provides a set of patched kernel
+headers to be used by userland applications (which installs in
+/usr/include/linux/, /usr/include/asm/, etc...). these are manually maintained
+by distribution packagers, and generated either manually or with various
+scripts. these headers are also tailored to GNU LibC and cannot be reused
+easily by Bionic.
+
+for a really long period, the kernel authors have stated that they don't want
+to fix the problem, even when someone proposed a patch to start cleaning the
+official headers. from their point of view this is purely a library author
+problem.
+
+fortunately, enlightnment happened, and the kernel now provides a way to
+install a set of "user-friendly" headers that are generated from the official
+ones by stripping the __KERNEL__ protected declarations.
+
+unfortunately, this is not enough for Bionic because the result still contains
+a few broken declarations that are difficult to route around. (see below for
+a little bit of details).
+
+we plan to be able to support these kernel-generated user-land headers in the
+future, but the priority on this issue is very low.
+
+
+WHAT WE DO:
+-----------
+
+so we're doomed to repeat the same effort than anyone else. the big difference
+here is that we want to automate as much as possible the generation of the
+clean headers to easily support additional architectures in the future,
+and keep current with upstream changes in the header definitions with the
+least possible hassle.
+
+of course, this is only a race to the bottom. the kernel maintainers still
+feel free to randomly break the structure of their headers (e.g. moving the
+location of some files) occasionally, so we'll need to keep up with that by
+updating our build script/original headers as these cases happen.
+
+what we do is keep a set of "original" kernel headers, and process them
+automatically to generate a set of "clean" headers that can be used from
+userland and the C library.
+
+note that the "original" headers can be tweaked a little to avoid some subtle
+issues. for example:
+
+- when the location of various USB-related headers changes in the kernel
+  source tree, we want to keep them at the same location in our generated
+  headers (there is no reason to break the userland API for something
+  like that).
+
+- sometimes, we prefer to take certain things out of blocks guarded by a
+  #ifdef __KERNEL__ .. #endif. for example, on recent kernels <linux/wireless.h>
+  only includes <linux/if.h> when in kernel mode. we make it available to
+  userland as well since some code out there assumes that this is the case.
+
+- sometimes, the header is simply incorrect (e.g. it uses a type without

+/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
+   The following encoding technique is taken from RFC 1521 by Borenstein
+   and Freed.  It is reproduced here in a slightly edited form for
+   convenience.
+
+   A 65-character subset of US-ASCII is used, enabling 6 bits to be
+   represented per printable character. (The extra 65th character, "=",
+   is used to signify a special processing function.)
+
+   The encoding process represents 24-bit groups of input bits as output
+   strings of 4 encoded characters. Proceeding from left to right, a
+   24-bit input group is formed by concatenating 3 8-bit input groups.
+   These 24 bits are then treated as 4 concatenated 6-bit groups, each
+   of which is translated into a single digit in the base64 alphabet.
+
+   Each 6-bit group is used as an index into an array of 64 printable
+   characters. The character referenced by the index is placed in the
+   output string.

+
+   Special processing is performed if fewer than 24 bits are available
+   at the end of the data being encoded.  A full encoding quantum is
+   always completed at the end of a quantity.  When fewer than 24 input
+   bits are available in an input group, zero bits are added (on the
+   right) to form an integral number of 6-bit groups.  Padding at the
+   end of the data is performed using the '=' character.
+
+   Since all base64 input is an integral number of octets, only the
+         -------------------------------------------------
+   following cases can arise:
+
+       (1) the final quantum of encoding input is an integral
+           multiple of 24 bits; here, the final unit of encoded
+	   output will be an integral multiple of 4 characters
+	   with no "=" padding,
+       (2) the final quantum of encoding input is exactly 8 bits;
+           here, the final unit of encoded output will be two
+	   characters followed by two "=" padding characters, or
+       (3) the final quantum of encoding input is exactly 16 bits;
+           here, the final unit of encoded output will be three
+	   characters followed by one "=" padding character.

+ * Issues to be discussed:
+ * - Thread safe-ness must be checked.
+ * - Return values.  There are nonstandard return values defined and used
+ *   in the source code.  This is because RFC2553 is silent about which error
+ *   code must be returned for which situation.
+ * - IPv4 classful (shortened) form.  RFC2553 is silent about it.  XNET 5.2
+ *   says to use inet_aton() to convert IPv4 numeric to binary (alows
+ *   classful form as a result).
+ *   current code - disallow classful form for IPv4 (due to use of inet_pton).
+ * - freeaddrinfo(NULL).  RFC2553 is silent about it.  XNET 5.2 says it is
+ *   invalid.
+ *   current code - SEGV on freeaddrinfo(NULL)
+ * Note:
+ * - We use getipnodebyname() just for thread-safeness.  There's no intent
+ *   to let it do PF_UNSPEC (actually we never pass PF_UNSPEC to
+ *   getipnodebyname().
+ * - The code filters out AFs that are not supported by the kernel,
+ *   when globbing NULL hostname (to loopback, or wildcard).  Is it the right
+ *   thing to do?  What is the relationship with post-RFC2553 AI_ADDRCONFIG
+ *   in ai_flags?
+ * - (post-2553) semantics of AI_ADDRCONFIG itself is too vague.
+ *   (1) what should we do against numeric hostname (2) what should we do
+ *   against NULL hostname (3) what is AI_ADDRCONFIG itself.  AF not ready?
+ *   non-loopback address configured?  global address configured?
+ * - To avoid search order issue, we have a big amount of code duplicate
+ *   from gethnamaddr.c and some other places.  The issues that there's no
+ *   lower layer function to lookup "IPv4 or IPv6" record.  Calling
+ *   gethostbyname2 from getaddrinfo will end up in wrong search order, as
+ *   follows:
+ *	- The code makes use of following calls when asked to resolver with
+ *	  ai_family  = PF_UNSPEC:
+ *		getipnodebyname(host, AF_INET6);
+ *		getipnodebyname(host, AF_INET);
+ *	  This will result in the following queries if the node is configure to
+ *	  prefer /etc/hosts than DNS:
+ *		lookup /etc/hosts for IPv6 address
+ *		lookup DNS for IPv6 address
+ *		lookup /etc/hosts for IPv4 address
+ *		lookup DNS for IPv4 address
+ *	  which may not meet people's requirement.
+ *	  The right thing to happen is to have underlying layer which does
+ *	  PF_UNSPEC lookup (lookup both) and return chain of addrinfos.
+ *	  This would result in a bit of code duplicate with _dns_ghbyname() and
+ *	  friends.

+/*
+ * Requirements:
+ * 
+ * 1. The thread safe mechanism should be lightweight so the library can
+ *    be used by non-threaded applications without unreasonable overhead.
+ * 
+ * 2. There should be no dependency on a thread engine for non-threaded
+ *    applications.
+ * 
+ * 3. There should be no dependency on any particular thread engine.
+ * 
+ * 4. The library should be able to be compiled without support for thread
+ *    safety.
+ * 
+ * 
+ * Rationale:
+ * 
+ * One approach for thread safety is to provide discrete versions of the
+ * library: one thread safe, the other not.  The disadvantage of this is
+ * that libc is rather large, and two copies of a library which are 99%+
+ * identical is not an efficent use of resources.
+ * 
+ * Another approach is to provide a single thread safe library.  However,
+ * it should not add significant run time or code size overhead to non-
+ * threaded applications.
+ * 
+ * Since the NetBSD C library is used in other projects, it should be
+ * easy to replace the mutual exclusion primitives with ones provided by
+ * another system.  Similarly, it should also be easy to remove all
+ * support for thread safety completely if the target environment does
+ * not support threads.
+ * 
+ * 
+ * Implementation Details:
+ * 
+ * The thread primitives used by the library (mutex_t, mutex_lock, etc.)
+ * are macros which expand to the cooresponding primitives provided by
+ * the thread engine or to nothing.  The latter is used so that code is
+ * not unreasonably cluttered with #ifdefs when all thread safe support
+ * is removed.
+ * 
+ * The thread macros can be directly mapped to the mutex primitives from
+ * pthreads, however it should be reasonably easy to wrap another mutex
+ * implementation so it presents a similar interface.
+ * 
+ * The thread functions operate by dispatching to symbols which are, by
+ * default, weak-aliased to no-op functions in thread-stub/thread-stub.c
+ * (some uses of thread operations are conditional on __isthreaded, but
+ * not all of them are).
+ *
+ * When the thread library is linked in, it provides strong-alias versions
+ * of those symbols which dispatch to its own real thread operations.
+ *
+ */
+
+#ifdef _REENTRANT
+
+/*
+ * Abtract thread interface for thread-safe libraries.  These routines
+ * will use stubs in libc if the application is not linked against the
+ * pthread library, and the real function in the pthread library if it
+ * is.

+/* This code implements a small and *simple* DNS resolver cache.
+ *
+ * It is only used to cache DNS answers for a maximum of CONFIG_SECONDS seconds
+ * in order to reduce DNS traffic. It is not supposed to be a full DNS cache,
+ * since we plan to implement that in the future in a dedicated process running
+ * on the system.
+ *
+ * Note that its design is kept simple very intentionally, i.e.:
+ *
+ *  - it takes raw DNS query packet data as input, and returns raw DNS
+ *    answer packet data as output
+ *
+ *    (this means that two similar queries that encode the DNS name
+ *     differently will be treated distinctly).
+ *
+ *  - the TTLs of answer RRs are ignored. our DNS resolver library does not use
+ *    them anyway, but it means that records with a TTL smaller than
+ *    CONFIG_SECONDS will be kept in the cache anyway.
+ *
+ *    this is bad, but we absolutely want to avoid parsing the answer packets
+ *    (and should be solved by the later full DNS cache process).
+ *
+ *  - the implementation is just a (query-data) => (answer-data) hash table
+ *    with a trivial least-recently-used expiration policy.
+ *
+ * Doing this keeps the code simple and avoids to deal with a lot of things
+ * that a full DNS cache is expected to do.
+ *
+ * The API is also very simple:
+ *
+ *   - the client calls _resolv_cache_get() to obtain a handle to the cache.
+ *     this will initialize the cache on first usage. the result can be NULL
+ *     if the cache is disabled.
+ *
+ *   - the client calls _resolv_cache_lookup() before performing a query
+ *
+ *     if the function returns RESOLV_CACHE_FOUND, a copy of the answer data
+ *     has been copied into the client-provided answer buffer.
+ *
+ *     if the function returns RESOLV_CACHE_NOTFOUND, the client should perform
+ *     a request normally, *then* call _resolv_cache_add() to add the received
+ *     answer to the cache.
+ *
+ *     if the function returns RESOLV_CACHE_UNSUPPORTED, the client should
+ *     perform a request normally, and *not* call _resolv_cache_add()
+ *
+ *     note that RESOLV_CACHE_UNSUPPORTED is also returned if the answer buffer
+ *     is too short to accomodate the cached result.
+ *
+ *  - when network settings change, the cache must be flushed since the list
+ *    of DNS servers probably changed. this is done by calling
+ *    _resolv_cache_reset()
+ *
+ *    the parameter to this function must be an ever-increasing generation
+ *    number corresponding to the current network settings state.
+ *
+ *    This is done because several threads could detect the same network
+ *    settings change (but at different times) and will all end up calling the
+ *    same function. Comparing with the last used generation number ensures
+ *    that the cache is only flushed once per network change.

+
+/* technical note:
+ *
+ *   the following debugging routines are used to append data to a bounded
+ *   buffer they take two parameters that are:
+ *
+ *   - p : a pointer to the current cursor position in the buffer
+ *         this value is initially set to the buffer's address.
+ *
+ *   - end : the address of the buffer's limit, i.e. of the first byte
+ *           after the buffer. this address should never be touched.
+ *
+ *           IMPORTANT: it is assumed that end > buffer_address, i.e.
+ *                      that the buffer is at least one byte.
+ *
+ *   the _bprint_() functions return the new value of 'p' after the data
+ *   has been appended, and also ensure the following:
+ *
+ *   - the returned value will never be strictly greater than 'end'
+ *
+ *   - a return value equal to 'end' means that truncation occured
+ *     (in which case, end[-1] will be set to 0)
+ *
+ *   - after returning from a _bprint_() function, the content of the buffer
+ *     is always 0-terminated, even in the event of truncation.
+ *
+ *  these conventions allow you to call _bprint_ functions multiple times and
+ *  only check for truncation at the end of the sequence, as in:
+ *
+ *     char  buff[1000], *p = buff, *end = p + sizeof(buff);

+ *
+ * the QUESTION is made of QDCount Question Record (QRs)
+ * the ANSWER is made of ANCount RRs
+ * the AUTHORITY is made of NSCount RRs
+ * the ADDITIONNAL is made of ARCount RRs
+ *
+ * Each Question Record (QR) is made of:
+ *
+ *   QNAME   : variable : Query DNS NAME
+ *   TYPE    : 16       : type of query (A=1, PTR=12, MX=15, AAAA=28, ALL=255)
+ *   CLASS   : 16       : class of query (IN=1)
+ *
+ * Each Resource Record (RR) is made of:
+ *
+ *   NAME    : variable : DNS NAME
+ *   TYPE    : 16       : type of query (A=1, PTR=12, MX=15, AAAA=28, ALL=255)
+ *   CLASS   : 16       : class of query (IN=1)
+ *   TTL     : 32       : seconds to cache this RR (0=none)
+ *   RDLENGTH: 16       : size of RDDATA in bytes
+ *   RDDATA  : variable : RR data (depends on TYPE)
+ *
+ * Each QNAME contains a domain name encoded as a sequence of 'labels'
+ * terminated by a zero. Each label has the following format:
+ *
+ *    LEN  : 8     : lenght of label (MUST be < 64)
+ *    NAME : 8*LEN : label length (must exclude dots)
+ *
+ * A value of 0 in the encoding is interpreted as the 'root' domain and
+ * terminates the encoding. So 'www.android.com' will be encoded as:
+ *
+ *   <3>www<7>android<3>com<0>
+ *
+ * Where <n> represents the byte with value 'n'
+ *
+ * Each NAME reflects the QNAME of the question, but has a slightly more
+ * complex encoding in order to provide message compression. This is achieved
+ * by using a 2-byte pointer, with format:
+ *
+ *    TYPE   : 2  : 0b11 to indicate a pointer, 0b01 and 0b10 are reserved
+ *    OFFSET : 14 : offset to another part of the DNS packet
+ *
+ * The offset is relative to the start of the DNS packet and must point
+ * A pointer terminates the encoding.
+ *
+ * The NAME can be encoded in one of the following formats:
+ *
+ *   - a sequence of simple labels terminated by 0 (like QNAMEs)
+ *   - a single pointer
+ *   - a sequence of simple labels terminated by a pointer
+ *
+ * A pointer shall always point to either a pointer of a sequence of
+ * labels (which can themselves be terminated by either a 0 or a pointer)
+ *
+ * The expanded length of a given domain name should not exceed 255 bytes.
+ *
+ * NOTE: we don't parse the answer packets, so don't need to deal with NAME
+ *       records, only QNAMEs.

+SHA-1 in C
+By Steve Reid <sreid@sea-to-sky.net>
+100% Public Domain
+
+-----------------
+Modified 7/98 
+By James H. Brown <jbrown@burgoyne.com>
+Still 100% Public Domain
+
+Corrected a problem which generated improper hash values on 16 bit machines
+Routine SHA1Update changed from
+	void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned int
+len)
+to
+	void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned
+long len)
+
+The 'len' parameter was declared an int which works fine on 32 bit machines.
+However, on 16 bit machines an int is too small for the shifts being done
+against
+it.  This caused the hash function to generate incorrect values if len was
+greater than 8191 (8K - 1) due to the 'len << 3' on line 3 of SHA1Update().
+
+Since the file IO in main() reads 16K at a time, any file 8K or larger would
+be guaranteed to generate the wrong hash (e.g. Test Vector #3, a million
+"a"s).
+
+I also changed the declaration of variables i & j in SHA1Update to 
+unsigned long from unsigned int for the same reason.
+
+These changes should make no difference to any 32 bit implementations since
+an
+int and a long are the same size in those environments.
+
+--
+I also corrected a few compiler warnings generated by Borland C.
+1. Added #include <process.h> for exit() prototype
+2. Removed unused variable 'j' in SHA1Final
+3. Changed exit(0) to return(0) at end of main.
+
+ALL changes I made can be located by searching for comments containing 'JHB'

+/* strtod for IEEE-, VAX-, and IBM-arithmetic machines.
+ *
+ * This strtod returns a nearest machine number to the input decimal
+ * string (or sets errno to ERANGE).  With IEEE arithmetic, ties are
+ * broken by the IEEE round-even rule.  Otherwise ties are broken by
+ * biased rounding (add half and chop).
+ *
+ * Inspired loosely by William D. Clinger's paper "How to Read Floating
+ * Point Numbers Accurately" [Proc. ACM SIGPLAN '90, pp. 92-101].
+ *
+ * Modifications:
+ *
+ *	1. We only require IEEE, IBM, or VAX double-precision
+ *		arithmetic (not IEEE double-extended).
+ *	2. We get by with floating-point arithmetic in a case that
+ *		Clinger missed -- when we're computing d * 10^n
+ *		for a small integer d and the integer n is not too
+ *		much larger than 22 (the maximum integer k for which
+ *		we can represent 10^k exactly), we may be able to
+ *		compute (d*10^k) * 10^(e-k) with just one roundoff.
+ *	3. Rather than a bit-at-a-time adjustment of the binary
+ *		result in the hard case, we use floating-point
+ *		arithmetic to determine the adjustment to within
+ *		one bit; only in really hard cases do we need to
+ *		compute a second residual.
+ *	4. Because of 3., we don't need a large table of powers of 10
+ *		for ten-to-e (just some small tables, e.g. of 10^k
+ *		for 0 <= k <= 22).

+ * Inspired by "How to Print Floating-Point Numbers Accurately" by
+ * Guy L. Steele, Jr. and Jon L. White [Proc. ACM SIGPLAN '90, pp. 92-101].
+ *
+ * Modifications:
+ *	1. Rather than iterating, we use a simple numeric overestimate
+ *	   to determine k = floor(log10(d)).  We scale relevant
+ *	   quantities using O(log2(k)) rather than O(k) multiplications.
+ *	2. For some modes > 2 (corresponding to ecvt and fcvt), we don't
+ *	   try to generate digits strictly left to right.  Instead, we
+ *	   compute with fewer bits and propagate the carry if necessary
+ *	   when rounding the final digit up.  This is often faster.
+ *	3. Under the assumption that input will be rounded nearest,
+ *	   mode 0 renders 1e23 as 1e23 rather than 9.999999999999999e22.
+ *	   That is, we allow equality in stopping tests when the
+ *	   round-nearest rule will give the same floating-point value
+ *	   as would satisfaction of the stopping test with strict
+ *	   inequality.
+ *	4. We remove common factors of powers of 2 from relevant
+ *	   quantities.
+ *	5. When converting floating-point integers less than 1e16,
+ *	   we use floating-point arithmetic rather than resorting
+ *	   to multiple-precision integers.
+ *	6. When asked to produce fewer than 15 digits, we first try
+ *	   to get by with floating-point arithmetic; we resort to
+ *	   multiple-precision integer arithmetic only if we cannot
+ *	   guarantee that the floating-point calculation has given
+ *	   the correctly rounded result.  For k requested digits and
+ *	   "uniformly" distributed input, the probability is
+ *	   something like 10^(k-15) that we must resort to the Long
+ *	   calculation.

+ * DOUBLE PRECISION (IEEE 53 bits, VAX D FORMAT 56 BITS)
+ * CODED IN C BY K.C. NG, 1/19/85;
+ * REVISED BY K.C. NG on 2/6/85, 2/15/85, 3/7/85, 3/24/85, 4/16/85, 6/14/86.
+ *
+ * Required system supported functions:
+ *	scalb(x,n)
+ *	copysign(x,y)
+ *	finite(x)
+ *
+ * Method:
+ *	1. Argument Reduction: given the input x, find r and integer k such
+ *	   that
+ *	                   x = k*ln2 + r,  |r| <= 0.5*ln2 .
+ *	   r will be represented as r := z+c for better accuracy.
+ *
+ *	2. Compute exp(r) by
+ *
+ *		exp(r) = 1 + r + r*R1/(2-R1),
+ *	   where
+ *		R1 = x - x^2*(p1+x^2*(p2+x^2*(p3+x^2*(p4+p5*x^2)))).
+ *
+ *	3. exp(x) = 2^k * exp(r) .
+ *
+ * Special cases:
+ *	exp(INF) is INF, exp(NaN) is NaN;
+ *	exp(-INF)=  0;
+ *	for finite argument, only exp(0)=1 is exact.
+ *
+ * Accuracy:
+ *	exp(x) returns the exponential of x nearly rounded. In a test run
+ *	with 1,156,000 random arguments on a VAX, the maximum observed
+ *	error was 0.869 ulps (units in the last place).

+ *	Logarithm in IEEE Floating-Point arithmetic." ACM Trans.
+ *	Math Software, vol 16. no 4, pp 378-400, Dec 1990).
+ *
+ * Calculates log(2^m*F*(1+f/F)), |f/j| <= 1/256,
+ * where F = j/128 for j an integer in [0, 128].
+ *
+ * log(2^m) = log2_hi*m + log2_tail*m
+ * since m is an integer, the dominant term is exact.
+ * m has at most 10 digits (for subnormal numbers),
+ * and log2_hi has 11 trailing zero bits.
+ *
+ * log(F) = logF_hi[j] + logF_lo[j] is in tabular form in log_table.h
+ * logF_hi[] + 512 is exact.
+ *
+ * log(1+f/F) = 2*f/(2*F + f) + 1/12 * (2*f/(2*F + f))**3 + ...
+ * the leading term is calculated to extra precision in two
+ * parts, the larger of which adds exactly to the dominant
+ * m and F terms.
+ * There are two cases:
+ *	1. when m, j are non-zero (m | j), use absolute
+ *	   precision for the leading term.
+ *	2. when m = j = 0, |1-x| < 1/256, and log(x) ~= (x-1).
+ *	   In this case, use a relative precision of 24 bits.
+ * (This is done differently in the original paper)

+.Ft double
+.Fn atan2 "double y" "double x"

+.Fn atan2f "float y" "float x"
+.Sh DESCRIPTION
+The
+.Fn atan2
+and the
+.Fn atan2f
+functions compute the principal value of the arc tangent of
+.Fa y/ Ns Ar x ,
+using the signs of both arguments to determine the quadrant of

+if
+.Ar x

+.El
+.Sh NOTES
+The function
+.Fn atan2
+defines "if x > 0,"
+.Fn atan2 0 0
+= 0 despite that previously
+.Fn atan2 0 0
+may have generated an error message.
+The reasons for assigning a value to
+.Fn atan2 0 0
+are these:
+.Bl -enum -offset indent
+.It
+Programs that test arguments to avoid computing
+.Fn atan2 0 0
+must be indifferent to its value.
+Programs that require it to be invalid are vulnerable
+to diverse reactions to that invalidity on diverse computer systems.
+.It
+The
+.Fn atan2
+function is used mostly to convert from rectangular (x,y)
+to polar
+.if n\
+(r,theta)
+.if t\
+(r,\(*h)
+coordinates that must satisfy x =
+.if n\
+r\(**cos theta
+.if t\
+r\(**cos\(*h
+and y =
+.if n\
+r\(**sin theta.
+.if t\
+r\(**sin\(*h.
+These equations are satisfied when (x=0,y=0)
+is mapped to
+.if n \
+(r=0,theta=0).
+.if t \
+(r=0,\(*h=0).
+In general, conversions to polar coordinates
+should be computed thus:
+.Bd -unfilled -offset indent
+.if n \{\
+r	:= hypot(x,y);  ... := sqrt(x\(**x+y\(**y)
+theta	:= atan2(y,x).
+.\}
+.if t \{\
+r	:= hypot(x,y);  ... := \(sr(x\u\s82\s10\d+y\u\s82\s10\d)
+\(*h	:= atan2(y,x).
+.\}
+.Ed
+.It
+The foregoing formulas need not be altered to cope in a
+reasonable way with signed zeros and infinities
+on a machine that conforms to
+.Tn IEEE 754 ;
+the versions of
+.Xr hypot 3
+and
+.Fn atan2
+provided for
+such a machine are designed to handle all cases.
+That is why
+.Fn atan2 \(+-0 \-0
+= \(+-\*(Pi
+for instance.
+In general the formulas above are equivalent to these:
+.Bd -unfilled -offset indent
+.if n \
+r := sqrt(x\(**x+y\(**y); if r = 0 then x := copysign(1,x);
+.if t \
+r := \(sr(x\(**x+y\(**y);\0\0if r = 0 then x := copysign(1,x);

+These functions will return the appropriate computation unless an error

+The functions
+.Fn pow x y
+and
+.Fn powf x y
+raise an invalid exception and return an \*(Na if
+.Fa x
+< 0 and
+.Fa y
+is not an integer.
+An attempt to take the logarithm of \*(Pm0 will result in
+a divide-by-zero exception, and an infinity will be returned.
+An attempt to take the logarithm of a negative number will
+result in an invalid exception, and an \*(Na will be generated.
+.Sh NOTES
+The functions exp(x)\-1 and log(1+x) are called
+expm1 and logp1 in
+.Tn BASIC
+on the Hewlett\-Packard
+.Tn HP Ns \-71B
+and
+.Tn APPLE
+Macintosh,
+.Tn EXP1
+and
+.Tn LN1
+in Pascal, exp1 and log1 in C
+on
+.Tn APPLE
+Macintoshes, where they have been provided to make
+sure financial calculations of ((1+x)**n\-1)/x, namely
+expm1(n\(**log1p(x))/x, will be accurate when x is tiny.
+They also provide accurate inverse hyperbolic functions.
+.Pp
+The function
+.Fn pow x 0
+returns x**0 = 1 for all x including x = 0, \*(If, and \*(Na .
+Previous implementations of pow may
+have defined x**0 to be undefined in some or all of these
+cases.
+Here are reasons for returning x**0 = 1 always:
+.Bl -enum -width indent
+.It
+Any program that already tests whether x is zero (or
+infinite or \*(Na) before computing x**0 cannot care
+whether 0**0 = 1 or not.
+Any program that depends
+upon 0**0 to be invalid is dubious anyway since that
+expression's meaning and, if invalid, its consequences
+vary from one computer system to another.
+.It
+Some Algebra texts (e.g.\& Sigler's) define x**0 = 1 for
+all x, including x = 0.
+This is compatible with the convention that accepts a[0]
+as the value of polynomial
+.Bd -literal -offset indent
+p(x) = a[0]\(**x**0 + a[1]\(**x**1 + a[2]\(**x**2 +...+ a[n]\(**x**n
+.Ed
+.Pp
+at x = 0 rather than reject a[0]\(**0**0 as invalid.
+.It
+Analysts will accept 0**0 = 1 despite that x**y can
+approach anything or nothing as x and y approach 0
+independently.
+The reason for setting 0**0 = 1 anyway is this:
+.Bd -ragged -offset indent
+If x(z) and y(z) are
+.Em any
+functions analytic (expandable
+in power series) in z around z = 0, and if there
+x(0) = y(0) = 0, then x(z)**y(z) \(-> 1 as z \(-> 0.
+.Ed
+.It
+If 0**0 = 1, then
+\*(If**0 = 1/0**0 = 1 too; and
+then \*(Na**0 = 1 too because x**0 = 1 for all finite
+and infinite x, i.e., independently of x.

+.Sh DESCRIPTION
+The
+.Fn feclearexcept
+routine clears the floating-point exception flags specified by

+whereas

+raises the specified exceptions.
+Raising an exception causes the corresponding flag to be set,
+and a

+is delivered to the process if the exception is unmasked.
+.Pp
+The
+.Fn fetestexcept
+function determines which flags are currently set, of those specified by
+.Fa excepts .
+.Pp
+The
+.Fn fegetexceptflag
+function stores the state of the exception flags specified in
+.Fa excepts
+in the opaque object pointed to by
+.Fa flagp .
+Similarly,
+.Fn fesetexceptflag
+changes the specified exception flags to reflect the state stored in
+the object pointed to by

+Note that the flags restored with

+must be a (not necessarily proper) subset of the flags recorded by

+.Pp
+For all of these functions, the possible types of exceptions
+include those described in
+.Xr fenv 3 .
+Some architectures may define other types of floating-point exceptions.
+.Sh IMPLEMENTATION NOTES
+On some architectures, raising an overflow or underflow exception
+also causes an inexact exception to be raised.
+In these cases, the overflow or underflow will be raised first.
+.Pp
+The
+.Fn fegetexceptflag
+and
+.Fn fesetexceptflag
+routines are preferred to
+.Fn fetestexcept
+and
+.Fn feraiseexcept ,
+respectively, for saving and restoring exception flags.
+The latter do not re-raise exceptions and may preserve
+architecture-specific information such as addresses where
+exceptions occurred.
+.Sh RETURN VALUES
+The
+.Fn feclearexcept ,
+.Fn fegetexceptflag ,
+.Fn feraiseexcept ,
+and
+.Fn fesetexceptflag
+functions return 0 upon success, and non-zero otherwise.
+The
+.Fn fetestexcept

+.Sh DESCRIPTION
+The
+.In fenv.h
+routines manipulate the floating-point environment,
+which includes the exception flags and rounding modes defined in
+.St -ieee754 .
+.Ss Exceptions
+Exception flags are set as side-effects of floating-point arithmetic
+operations and math library routines, and they remain set until
+explicitly cleared.
+The following macros expand to bit flags of type
+.Vt int
+representing the five standard floating-point exceptions.
+.Bl -tag -width ".Dv FE_DIVBYZERO"
+.It Dv FE_DIVBYZERO
+A divide-by-zero exception occurs when the program attempts to
+divide a finite non-zero number by zero.
+.It Dv FE_INEXACT
+An inexact exception is raised whenever there is a loss of precision
+due to rounding.
+.It Dv FE_INVALID
+Invalid operation exceptions occur when a program attempts to
+perform calculations for which there is no reasonable representable
+answer.
+For instance, subtraction of infinities, division of zero by zero,
+ordered comparison involving \*(Nas, and taking the square root of a
+negative number are all invalid operations.
+.It Dv FE_OVERFLOW
+An overflow exception occurs when the magnitude of the result of a
+computation is too large to fit in the destination type.
+.It Dv FE_UNDERFLOW
+Underflow occurs when the result of a computation is too close to zero
+to be represented as a non-zero value in the destination type.
+.El
+.Pp
+Additionally, the
+.Dv FE_ALL_EXCEPT
+macro expands to the bitwise OR of the above flags and any
+architecture-specific flags.
+Combinations of these flags are passed to the
+.Fn feclearexcept ,
+.Fn fegetexceptflag ,
+.Fn feraiseexcept ,
+.Fn fesetexceptflag ,
+and
+.Fn fetestexcept
+functions to clear, save, raise, restore, and examine the
+processor's floating-point exception flags, respectively.
+.Pp
+Exceptions may be
+.Em unmasked
+with
+.Fn feenableexcept
+and masked with
+.Fn fedisableexcept .
+Unmasked exceptions cause a trap when they are produced, and
+all exceptions are masked by default.
+The current mask can be tested with
+.Fn fegetexcept .
+.Ss Rounding Modes
+.St -ieee754
+specifies four rounding modes.
+These modes control the direction in which results are rounded
+from their exact values in order to fit them into binary
+floating-point variables.
+The four modes correspond with the following symbolic constants.
+.Bl -tag -width ".Dv FE_TOWARDZERO"
+.It Dv FE_TONEAREST
+Results are rounded to the closest representable value.
+If the exact result is exactly half way between two representable
+values, the value whose last binary digit is even (zero) is chosen.

+The
+.Fn fegetround
+and
+.Fn fesetround
+functions query and set the rounding mode.
+.Ss Environment Control
+The
+.Fn fegetenv
+and
+.Fn fesetenv
+functions save and restore the floating-point environment,
+which includes exception flags, the current exception mask,
+the rounding mode, and possibly other implementation-specific
+state.
+The
+.Fn feholdexcept
+function behaves like
+.Fn fegetenv ,
+but with the additional effect of clearing the exception flags and
+installing a
+.Em non-stop
+mode.
+In non-stop mode, floating-point operations will set exception flags
+as usual, but no
+.Dv SIGFPE
+signals will be generated as a result.
+Non-stop mode is the default, but it may be altered by
+non-standard mechanisms.
+.\" XXX Mention fe[gs]etmask() here after the interface is finalized
+.\" XXX and ready to be officially documented.
+The
+.Fn feupdateenv
+function restores a saved environment similarly to
+.Fn fesetenv ,
+but it also re-raises any floating-point exceptions from the old
+environment.
+.Pp
+The macro
+.Dv FE_DFL_ENV
+expands to a pointer to the default environment.
+.Sh CAVEATS
+The FENV_ACCESS pragma can be enabled with
+.Dl "#pragma STDC FENV_ACCESS ON"
+and disabled with the
+.Dl "#pragma STDC FENV_ACCESS OFF"
+directive.
+This lexically-scoped annotation tells the compiler that the program
+may access the floating-point environment, so optimizations that would
+violate strict IEEE-754 semantics are disabled.
+If execution reaches a block of code for which
+.Dv FENV_ACCESS
+is off, the floating-point environment will become undefined.
+.Sh EXAMPLES
+The following routine computes the square root function.
+It explicitly raises an invalid exception on appropriate inputs using
+.Fn feraiseexcept .
+It also defers inexact exceptions while it computes intermediate
+values, and then it allows an inexact exception to be raised only if
+the final answer is inexact.
+.Bd -literal -offset indent
+#pragma STDC FENV_ACCESS ON
+double sqrt(double n) {
+	double x = 1.0;
+	fenv_t env;
+
+	if (isnan(n) || n < 0.0) {
+		feraiseexcept(FE_INVALID);
+		return (NAN);
+	}
+	if (isinf(n) || n == 0.0)
+		return (n);
+	feholdexcept(&env);
+	while (fabs((x * x) - n) > DBL_EPSILON * 2 * x)
+		x = (x / 2) + (n / (2 * x));

+.In math.h
+.Ft double
+.Fn fma "double x" "double y" "double z"
+.Ft float
+.Fn fmaf "float x" "float y" "float z"
+.Ft long double
+.Fn fmal "long double x" "long double y" "long double z"
+.Sh DESCRIPTION
+The
+.Fn fma ,
+.Fn fmaf ,
+and
+.Fn fmal
+functions return
+.No "(x * y) + z" ,
+computed with only one rounding error.
+Using the ordinary multiplication and addition operators, by contrast,
+results in two roundings: one for the intermediate product and one for
+the final result.
+.Pp
+For instance, the expression
+.No "1.2e100 * 2.0e208 - 1.4e308"
+produces \*(If due to overflow in the intermediate product, whereas
+.No "fma(1.2e100, 2.0e208, -1.4e308)"
+returns approximately 1.0e308.
+.Pp
+The fused multiply-add operation is often used to improve the
+accuracy of calculations such as dot products.
+It may also be used to improve performance on machines that implement
+it natively.
+The macros
+.Dv FP_FAST_FMA ,
+.Dv FP_FAST_FMAF
+and
+.Dv FP_FAST_FMAL
+may be defined in
+.In math.h
+to indicate that
+.Fn fma ,
+.Fn fmaf ,
+and
+.Fn fmal
+(respectively) have comparable or faster speed than a multiply
+operation followed by an add operation.
+.Sh IMPLEMENTATION NOTES
+In general, these routines will behave as one would expect if
+.No "x * y + z"
+were computed with unbounded precision and range,
+then rounded to the precision of the return type.
+However, on some platforms, if
+.Fa z
+is \*(Na, these functions may not raise an exception even
+when the computation of
+.No "x * y"
+would have otherwise generated an invalid exception.
+.Sh SEE ALSO

+.Sh STANDARDS

+Some \*(Nas, called Signaling \*(Nas, trap any floating-point operation
+performed upon them; they are used to mark missing
+or uninitialized values, or nonexistent elements

+The rest are Quiet \*(Nas; they are
+the default results of Invalid Operations, and
+propagate through subsequent arithmetic operations.
+If x \(!= x then x is \*(Na; every other predicate

+.Pp
+Rounding:
+.Bd -ragged -offset indent -compact
+Every algebraic operation (+, \-, \(**, /,
+\(sr)
+is rounded by default to within half an
+.Em ulp ,
+and when the rounding error is exactly half an
+.Em ulp
+then
+the rounded value's least significant bit is zero.
+(An
+.Em ulp
+is one
+.Em U Ns nit
+in the
+.Em L Ns ast
+.Em P Ns lace . )
+This kind of rounding is usually the best kind,
+sometimes provably so; for instance, for every
+x = 1.0, 2.0, 3.0, 4.0, ..., 2.0**52, we find
+(x/3.0)\(**3.0 == x and (x/10.0)\(**10.0 == x and ...
+despite that both the quotients and the products
+have been rounded.
+Only rounding like IEEE 754 can do that.
+But no single kind of rounding can be
+proved best for every circumstance, so IEEE 754
+provides rounding towards zero or towards
++\*(If or towards \-\*(If
+at the programmer's option.
+.Ed
+.Pp
+Exceptions:
+.Bd -ragged -offset indent -compact
+IEEE 754 recognizes five kinds of floating-point exceptions,
+listed below in declining order of probable importance.
+.Bl -column -offset indent "Invalid Operation" "Gradual Underflow"
+.Em "Exception	Default Result"
+Invalid Operation	\*(Na, or FALSE
+Overflow	\(+-\*(If
+Divide by Zero	\(+-\*(If
+Underflow	Gradual Underflow
+Inexact	Rounded value
+.El
+.Pp
+NOTE: An Exception is not an Error unless handled
+badly.
+What makes a class of exceptions exceptional
+is that no single default response can be satisfactory
+in every instance.
+On the other hand, if a default
+response will serve most instances satisfactorily,
+the unsatisfactory instances cannot justify aborting
+computation every time the exception occurs.

+.Ss Additional Information Regarding Exceptions
+.Pp
+For each kind of floating-point exception, IEEE 754
+provides a Flag that is raised each time its exception
+is signaled, and stays raised until the program resets
+it.
+Programs may also test, save and restore a flag.
+Thus, IEEE 754 provides three ways by which programs
+may cope with exceptions for which the default result
+might be unsatisfactory:
+.Bl -enum
+.It
+Test for a condition that might cause an exception
+later, and branch to avoid the exception.
+.It
+Test a flag to see whether an exception has occurred
+since the program last reset its flag.
+.It
+Test a result to see whether it is a value that only
+an exception could have produced.
+.Pp
+CAUTION: The only reliable ways to discover
+whether Underflow has occurred are to test whether
+products or quotients lie closer to zero than the
+underflow threshold, or to test the Underflow
+flag.
+(Sums and differences cannot underflow in
+IEEE 754; if x \(!= y then x\-y is correct to
+full precision and certainly nonzero regardless of
+how tiny it may be.)
+Products and quotients that
+underflow gradually can lose accuracy gradually
+without vanishing, so comparing them with zero
+(as one might on a VAX) will not reveal the loss.
+Fortunately, if a gradually underflowed value is
+destined to be added to something bigger than the
+underflow threshold, as is almost always the case,
+digits lost to gradual underflow will not be missed
+because they would have been rounded off anyway.
+So gradual underflows are usually
+.Em provably
+ignorable.
+The same cannot be said of underflows flushed to 0.
+.El
+.Pp
+At the option of an implementor conforming to IEEE 754,
+other ways to cope with exceptions may be provided:
+.Bl -enum
+.It
+ABORT.
+This mechanism classifies an exception in
+advance as an incident to be handled by means
+traditionally associated with error-handling
+statements like "ON ERROR GO TO ...".
+Different
+languages offer different forms of this statement,
+but most share the following characteristics:
+.Bl -dash
+.It
+No means is provided to substitute a value for
+the offending operation's result and resume
+computation from what may be the middle of an
+expression.
+An exceptional result is abandoned.
+.It
+In a subprogram that lacks an error-handling
+statement, an exception causes the subprogram to
+abort within whatever program called it, and so
+on back up the chain of calling subprograms until
+an error-handling statement is encountered or the
+whole task is aborted and memory is dumped.
+.El
+.It
+STOP.
+This mechanism, requiring an interactive
+debugging environment, is more for the programmer
+than the program.
+It classifies an exception in
+advance as a symptom of a programmer's error; the
+exception suspends execution as near as it can to
+the offending operation so that the programmer can
+look around to see how it happened.
+Quite often
+the first several exceptions turn out to be quite
+unexceptionable, so the programmer ought ideally
+to be able to resume execution after each one as if
+execution had not been stopped.
+.It
+\&... Other ways lie beyond the scope of this document.
+.El
+.Pp
+Ideally, each
+elementary function should act as if it were indivisible, or
+atomic, in the sense that ...
+.Bl -enum
+.It
+No exception should be signaled that is not deserved by
+the data supplied to that function.
+.It
+Any exception signaled should be identified with that
+function rather than with one of its subroutines.
+.It
+The internal behavior of an atomic function should not
+be disrupted when a calling program changes from
+one to another of the five or so ways of handling
+exceptions listed above, although the definition
+of the function may be correlated intentionally
+with exception handling.
+.El
+.Pp
+The functions in
+.Nm libm
+are only approximately atomic.
+They signal no inappropriate exception except possibly ...
+.Bl -tag -width indent -offset indent -compact
+.It Xo
+Over/Underflow
+.Xc
+when a result, if properly computed, might have lain barely within range, and
+.It Xo
+Inexact in
+.Fn cabs ,
+.Fn cbrt ,
+.Fn hypot ,
+.Fn log10
+and
+.Fn pow
+.Xc
+when it happens to be exact, thanks to fortuitous cancellation of errors.
+.El
+Otherwise, ...
+.Bl -tag -width indent -offset indent -compact
+.It Xo
+Invalid Operation is signaled only when
+.Xc
+any result but \*(Na would probably be misleading.
+.It Xo
+Overflow is signaled only when
+.Xc
+the exact result would be finite but beyond the overflow threshold.
+.It Xo
+Divide-by-Zero is signaled only when
+.Xc
+a function takes exactly infinite values at finite operands.
+.It Xo
+Underflow is signaled only when
+.Xc
+the exact result would be nonzero but tinier than the underflow threshold.
+.It Xo
+Inexact is signaled only when
+.Xc
+greater range or precision would be needed to represent the exact result.

+.Pp
+The external integer
+.Fa signgam
+returns the sign of \(*G(x).
+.Pp
+.Fn lgamma_r x signgamp
+and
+.Fn lgammaf_r x signgamp
+provide the same functionality as
+.Fn lgamma x
+and
+.Fn lgammaf x
+but the caller must provide an integer to store the sign of \(*G(x).
+.Pp
+.Fn gamma ,
+.Fn gammaf ,
+.Fn gamma_r ,
+and
+.Fn gammaf_r
+are deprecated aliases for
+.Fn lgamma ,
+.Fn lgammaf ,
+.Fn lgamma_r ,
+and
+.Fn lgammaf_r ,
+respectively.
+.Fn tgamma x
+returns \(*G(x), with no effect on
+.Fa signgam .
+.Sh IDIOSYNCRASIES
+Do not use the expression
+.Dq Li signgam\(**exp(lgamma(x))
+to compute g := \(*G(x).
+Instead use a program like this (in C):
+.Bd -literal -offset indent
+lg = lgamma(x); g = signgam\(**exp(lg);
+.Ed
+.Pp
+Only after
+.Fn lgamma
+or
+.Fn lgammaf
+has returned can signgam be correct.
+.Pp
+For arguments in its range,
+.Fn tgamma
+is preferred, as for positive arguments
+it is accurate to within one unit in the last place.
+Exponentiation of
+.Fn lgamma
+will lose up to 10 significant bits.
+.Sh RETURN VALUES

+.Fn gamma_r ,
+.Fn gammaf ,
+.Fn gammaf_r ,
+.Fn lgamma ,
+.Fn lgamma_r ,
+.Fn lgammaf ,
+and
+.Fn lgammaf_r
+return appropriate values unless an argument is out of range.
+Overflow will occur for sufficiently large positive values, and
+non-positive integers.
+For large non-integer negative values,
+.Fn tgamma
+will underflow.

+.Sh HISTORY
+A math library with many of the present functions appeared in
+.At v7 .
+The library was substantially rewritten for

+to provide
+better accuracy and speed on machines supporting either VAX
+or IEEE 754 floating-point.
+Most of this library was replaced with FDLIBM, developed at Sun
+Microsystems, in
+.Fx 1.1.5 .
+Additional routines, including ones for
+.Vt float
+and
+.Vt long double
+values, were written for or imported into subsequent versions of FreeBSD.
+.Sh BUGS
+The
+.Fn log2
+and
+.Fn nan
+functions are missing, and many functions are not available in their
+.Vt "long double"
+variants.
+.Pp
+Many of the routines to compute transcendental functions produce
+inaccurate results in other than the default rounding mode.
+.Pp
+On some architectures, trigonometric argument reduction is not
+performed accurately, resulting in errors greater than 1
+.Em ulp
+for large arguments to
+.Fn cos ,
+.Fn sin ,
+and
+.Fn tan .

+ * Returns the exponential of x.
+ *
+ * Method
+ *   1. Argument reduction:
+ *      Reduce x to an r so that |r| <= 0.5*ln2 ~ 0.34658.
+ *	Given x, find r and integer k such that
+ *
+ *               x = k*ln2 + r,  |r| <= 0.5*ln2.  
+ *
+ *      Here r will be represented as r = hi-lo for better 
+ *	accuracy.
+ *
+ *   2. Approximation of exp(r) by a special rational function on
+ *	the interval [0,0.34658]:
+ *	Write
+ *	    R(r**2) = r*(exp(r)+1)/(exp(r)-1) = 2 + r*r/6 - r**4/360 + ...
+ *      We use a special Remes algorithm on [0,0.34658] to generate 
+ * 	a polynomial of degree 5 to approximate R. The maximum error 
+ *	of this polynomial approximation is bounded by 2**-59. In
+ *	other words,
+ *	    R(z) ~ 2.0 + P1*z + P2*z**2 + P3*z**3 + P4*z**4 + P5*z**5
+ *  	(where z=r*r, and the values of P1 to P5 are listed below)

+ *	    | 2.0+P1*z+...+P5*z   -  R(z) | <= 2 
+ *	    |                             |
+ *	The computation of exp(r) thus becomes
+ *                             2*r
+ *		exp(r) = 1 + -------
+ *		              R - r
+ *                                 r*R1(r)

+ *	2. Reduce x to |x| since j0(x)=j0(-x),  and
+ *	   for x in (0,2)

+ * 		j0(x) = sqrt(2/(pi*x))*(p0(x)*cos(x0)-q0(x)*sin(x0))
+ * 	   where x0 = x-pi/4. It is better to compute sin(x0),cos(x0)
+ *	   as follow:

+ *			= 1/sqrt(2) * (cos(x) + sin(x))
+ *		sin(x0) = sin(x)cos(pi/4)-cos(x)sin(pi/4)
+ *			= 1/sqrt(2) * (sin(x) - cos(x))
+ * 	   (To avoid cancellation, use
+ *		sin(x) +- cos(x) = -cos(2x)/(sin(x) -+ cos(x))
+ * 	    to compute the worse one.)
+ *	   
+ *	3 Special cases
+ *		j0(nan)= nan
+ *		j0(0) = 1
+ *		j0(inf) = 0
+ *		
+ * Method -- y0(x):
+ *	1. For x<2.
+ *	   Since 
+ *		y0(x) = 2/pi*(j0(x)*(ln(x/2)+Euler) + x^2/4 - ...)
+ *	   therefore y0(x)-2/pi*j0(x)*ln(x) is an even function.
+ *	   We use the following function to approximate y0,
+ *		y0(x) = U(z)/V(z) + (2/pi)*(j0(x)*ln(x)), z= x^2
+ *	   where 
+ *		U(z) = u00 + u01*z + ... + u06*z^6
+ *		V(z) = 1  + v01*z + ... + v04*z^4
+ *	   with absolute approximation error bounded by 2**-72.
+ *	   Note: For tiny x, U/V = u0 and j0(x)~1, hence
+ *		y0(tiny) = u0 + (2/pi)*ln(tiny), (choose tiny<2**-27)
+ *	2. For x>=2.
+ * 		y0(x) = sqrt(2/(pi*x))*(p0(x)*cos(x0)+q0(x)*sin(x0))
+ * 	   where x0 = x-pi/4. It is better to compute sin(x0),cos(x0)
+ *	   by the method mentioned above.
+ *	3. Special cases: y0(0)=-inf, y0(x<0)=NaN, y0(inf)=0.

+/* __ieee754_j1(x), __ieee754_y1(x)
+ * Bessel function of the first and second kinds of order zero.
+ * Method -- j1(x):
+ *	1. For tiny x, we use j1(x) = x/2 - x^3/16 + x^5/384 - ...
+ *	2. Reduce x to |x| since j1(x)=-j1(-x),  and
+ *	   for x in (0,2)
+ *		j1(x) = x/2 + x*z*R0/S0,  where z = x*x;
+ *	   (precision:  |j1/x - 1/2 - R0/S0 |<2**-61.51 )
+ *	   for x in (2,inf)
+ * 		j1(x) = sqrt(2/(pi*x))*(p1(x)*cos(x1)-q1(x)*sin(x1))
+ * 		y1(x) = sqrt(2/(pi*x))*(p1(x)*sin(x1)+q1(x)*cos(x1))
+ * 	   where x1 = x-3*pi/4. It is better to compute sin(x1),cos(x1)
+ *	   as follow:
+ *		cos(x1) =  cos(x)cos(3pi/4)+sin(x)sin(3pi/4)
+ *			=  1/sqrt(2) * (sin(x) - cos(x))
+ *		sin(x1) =  sin(x)cos(3pi/4)-cos(x)sin(3pi/4)
+ *			= -1/sqrt(2) * (sin(x) + cos(x))
+ * 	   (To avoid cancellation, use
+ *		sin(x) +- cos(x) = -cos(2x)/(sin(x) -+ cos(x))
+ * 	    to compute the worse one.)
+ *	   
+ *	3 Special cases
+ *		j1(nan)= nan
+ *		j1(0) = 0
+ *		j1(inf) = 0
+ *		
+ * Method -- y1(x):
+ *	1. screen out x<=0 cases: y1(0)=-inf, y1(x<0)=NaN 
+ *	2. For x<2.
+ *	   Since 
+ *		y1(x) = 2/pi*(j1(x)*(ln(x/2)+Euler)-1/x-x/2+5/64*x^3-...)
+ *	   therefore y1(x)-2/pi*j1(x)*ln(x)-1/x is an odd function.
+ *	   We use the following function to approximate y1,
+ *		y1(x) = x*U(z)/V(z) + (2/pi)*(j1(x)*ln(x)-1/x), z= x^2
+ *	   where for x in [0,2] (abs err less than 2**-65.89)
+ *		U(z) = U0[0] + U0[1]*z + ... + U0[4]*z^4
+ *		V(z) = 1  + v0[0]*z + ... + v0[4]*z^5
+ *	   Note: For tiny x, 1/x dominate y1 and hence
+ *		y1(tiny) = -2/pi/tiny, (choose tiny<2**-54)
+ *	3. For x>=2.
+ * 		y1(x) = sqrt(2/(pi*x))*(p1(x)*sin(x1)+q1(x)*cos(x1))
+ * 	   where x1 = x-3*pi/4. It is better to compute sin(x1),cos(x1)
+ *	   by method mentioned above.

+/* __ieee754_lgamma_r(x, signgamp)
+ * Reentrant version of the logarithm of the Gamma function 
+ * with user provide pointer for the sign of Gamma(x). 
+ *
+ * Method:
+ *   1. Argument Reduction for 0 < x <= 8
+ * 	Since gamma(1+s)=s*gamma(s), for x in [0,8], we may 
+ * 	reduce x to a number in [1.5,2.5] by
+ * 		lgamma(1+s) = log(s) + lgamma(s)
+ *	for example,
+ *		lgamma(7.3) = log(6.3) + lgamma(6.3)
+ *			    = log(6.3*5.3) + lgamma(5.3)
+ *			    = log(6.3*5.3*4.3*3.3*2.3) + lgamma(2.3)
+ *   2. Polynomial approximation of lgamma around its
+ *	minimun ymin=1.461632144968362245 to maintain monotonicity.
+ *	On [ymin-0.23, ymin+0.27] (i.e., [1.23164,1.73163]), use
+ *		Let z = x-ymin;
+ *		lgamma(x) = -1.214862905358496078218 + z^2*poly(z)
+ *	where
+ *		poly(z) is a 14 degree polynomial.
+ *   2. Rational approximation in the primary interval [2,3]
+ *	We use the following approximation:
+ *		s = x-2.0;
+ *		lgamma(x) = 0.5*s + s*P(s)/Q(s)
+ *	with accuracy
+ *		|P/Q - (lgamma(x)-0.5s)| < 2**-61.71
+ *	Our algorithms are based on the following observation
+ *
+ *                             zeta(2)-1    2    zeta(3)-1    3
+ * lgamma(2+s) = s*(1-Euler) + --------- * s  -  --------- * s  + ...
+ *                                 2                 3
+ *
+ *	where Euler = 0.5771... is the Euler constant, which is very
+ *	close to 0.5.
+ *
+ *   3. For x>=8, we have
+ *	lgamma(x)~(x-0.5)log(x)-x+0.5*log(2pi)+1/(12x)-1/(360x**3)+....
+ *	(better formula:
+ *	   lgamma(x)~(x-0.5)*(log(x)-1)-.5*(log(2pi)-1) + ...)
+ *	Let z = 1/x, then we approximation
+ *		f(z) = lgamma(x) - (x-0.5)(log(x)-1)
+ *	by
+ *	  			    3       5             11
+ *		w = w0 + w1*z + w2*z  + w3*z  + ... + w6*z
+ *	where 
+ *		|w - f(z)| < 2**-58.74
+ *		
+ *   4. For negative x, since (G is gamma function)
+ *		-x*G(-x)*G(x) = pi/sin(pi*x),
+ * 	we have
+ * 		G(x) = pi/(sin(pi*x)*(-x)*G(-x))
+ *	since G(-x) is positive, sign(G(x)) = sign(sin(pi*x)) for x<0
+ *	Hence, for x<0, signgam = sign(sin(pi*x)) and 
+ *		lgamma(x) = log(|Gamma(x)|)
+ *			  = log(pi/(|x*sin(pi*x)|)) - lgamma(-x);
+ *	Note: one should avoid compute pi*(-x) directly in the 
+ *	      computation of sin(pi*(-x)).
+ *		
+ *   5. Special Cases
+ *		lgamma(2+s) ~ s*(1-Euler) for tiny s
+ *		lgamma(1)=lgamma(2)=0
+ *		lgamma(x) ~ -log(x) for tiny x
+ *		lgamma(0) = lgamma(inf) = inf
+ *	 	lgamma(-integer) = +-inf

+/* __ieee754_log(x)
+ * Return the logrithm of x
+ *
+ * Method :                  
+ *   1. Argument Reduction: find k and f such that 
+ *			x = 2^k * (1+f), 
+ *	   where  sqrt(2)/2 < 1+f < sqrt(2) .
+ *
+ *   2. Approximation of log(1+f).
+ *	Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
+ *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
+ *	     	 = 2s + s*R
+ *      We use a special Reme algorithm on [0,0.1716] to generate 
+ * 	a polynomial of degree 14 to approximate R The maximum error 
+ *	of this polynomial approximation is bounded by 2**-58.45. In
+ *	other words,
+ *		        2      4      6      8      10      12      14
+ *	    R(z) ~ Lg1*s +Lg2*s +Lg3*s +Lg4*s +Lg5*s  +Lg6*s  +Lg7*s
+ *  	(the values of Lg1 to Lg7 are listed in the program)
+ *	and
+ *	    |      2          14          |     -58.45
+ *	    | Lg1*s +...+Lg7*s    -  R(z) | <= 2 
+ *	    |                             |
+ *	Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
+ *	In order to guarantee error in log below 1ulp, we compute log
+ *	by
+ *		log(1+f) = f - s*(f - R)	(if f is not too large)
+ *		log(1+f) = f - (hfsq - s*(hfsq+R)).	(better accuracy)
+ *	
+ *	3. Finally,  log(x) = k*ln2 + log(1+f).  
+ *			    = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
+ *	   Here ln2 is split into two floating point number: 
+ *			ln2_hi + ln2_lo,
+ *	   where n*ln2_hi is always exact for |n| < 2000.
+ *
+ * Special cases:
+ *	log(x) is NaN with signal if x < 0 (including -INF) ; 
+ *	log(+INF) is +INF; log(0) is -INF with signal;
+ *	log(NaN) is that NaN with no signal.
+ *
+ * Accuracy:
+ *	according to an error analysis, the error is always less than
+ *	1 ulp (unit in the last place).
+ *
+ * Constants:
+ * The hexadecimal values are the intended ones for the following 
+ * constants. The decimal values may be used, provided that the 
+ * compiler will convert from decimal to binary accurately enough 
+ * to produce the hexadecimal values shown.

+ * Method:  Let x =  2   * (1+f)
+ *	1. Compute and return log2(x) in two pieces:
+ *		log2(x) = w1 + w2,
+ *	   where w1 has 53-24 = 29 bit trailing zeros.
+ *	2. Perform y*log2(x) = n+y' by simulating muti-precision 
+ *	   arithmetic, where |y'|<=0.5.
+ *	3. Return x**y = 2**n*exp(y'*log2)
+ *
+ * Special cases:
+ *	1.  (anything) ** 0  is 1
+ *	2.  (anything) ** 1  is itself
+ *	3.  (anything) ** NAN is NAN
+ *	4.  NAN ** (anything except 0) is NAN
+ *	5.  +-(|x| > 1) **  +INF is +INF
+ *	6.  +-(|x| > 1) **  -INF is +0
+ *	7.  +-(|x| < 1) **  +INF is +0
+ *	8.  +-(|x| < 1) **  -INF is +INF
+ *	9.  +-1         ** +-INF is NAN
+ *	10. +0 ** (+anything except 0, NAN)               is +0
+ *	11. -0 ** (+anything except 0, NAN, odd integer)  is +0
+ *	12. +0 ** (-anything except 0, NAN)               is +INF
+ *	13. -0 ** (-anything except 0, NAN, odd integer)  is +INF
+ *	14. -0 ** (odd integer) = -( +0 ** (odd integer) )
+ *	15. +INF ** (+anything except 0,NAN) is +INF
+ *	16. +INF ** (-anything except 0,NAN) is +0
+ *	17. -INF ** (anything)  = -0 ** (-anything)
+ *	18. (-anything) ** (integer) is (-1)**(integer)*(+anything**integer)
+ *	19. (-anything except 0 and inf) ** (non-integer) is NAN
+ *
+ * Accuracy:
+ *	pow(x,y) returns x**y nearly rounded. In particular
+ *			pow(integer,integer)
+ *	always returns the correct integer provided it is 
+ *	representable.
+ *
+ * Constants :
+ * The hexadecimal values are the intended ones for the following 
+ * constants. The decimal values may be used, provided that the 
+ * compiler will convert from decimal to binary accurately enough 
+ * to produce the hexadecimal values shown.

+ * Return correctly rounded sqrt.
+ *           ------------------------------------------
+ *	     |  Use the hardware sqrt if you have one |
+ *           ------------------------------------------
+ * Method: 
+ *   Bit by bit method using integer arithmetic. (Slow, but portable) 
+ *   1. Normalization
+ *	Scale x to y in [1,4) with even powers of 2: 
+ *	find an integer k such that  1 <= (y=x*2^(2k)) < 4, then
+ *		sqrt(x) = 2^k * sqrt(y)
+ *   2. Bit by bit computation
+ *	Let q  = sqrt(y) truncated to i bit after binary point (q = 1),
+ *	     i							 0
+ *                                     i+1         2
+ *	    s  = 2*q , and	y  =  2   * ( y - q  ).		(1)
+ *	     i      i            i                 i
+ *                                                        
+ *	To compute q    from q , one checks whether 
+ *		    i+1       i                       
+ *
+ *			      -(i+1) 2
+ *			(q + 2      ) <= y.			(2)
+ *     			  i
+ *							      -(i+1)
+ *	If (2) is false, then q   = q ; otherwise q   = q  + 2      .
+ *		 	       i+1   i             i+1   i
+ *
+ *	With some algebric manipulation, it is not difficult to see
+ *	that (2) is equivalent to 
+ *                             -(i+1)
+ *			s  +  2       <= y			(3)
+ *			 i                i
+ *
+ *	The advantage of (3) is that s  and y  can be computed by 
+ *				      i      i
+ *	the following recurrence formula:
+ *	    if (3) is false
+ *
+ *	    s     =  s  ,	y    = y   ;			(4)
+ *	     i+1      i		 i+1    i
+ *
+ *	    otherwise,
+ *                         -i                     -(i+1)
+ *	    s	  =  s  + 2  ,  y    = y  -  s  - 2  		(5)
+ *           i+1      i          i+1    i     i
+ *				
+ *	One may easily use induction to prove (4) and (5). 
+ *	Note. Since the left hand side of (3) contain only i+2 bits,
+ *	      it does not necessary to do a full (53-bit) comparison 
+ *	      in (3).
+ *   3. Final rounding
+ *	After generating the 53 bits result, we compute one more bit.
+ *	Together with the remainder, we can decide whether the
+ *	result is exact, bigger than 1/2ulp, or less than 1/2ulp
+ *	(it will never equal to 1/2ulp).
+ *	The rounding mode can be detected by checking whether
+ *	huge + tiny is equal to huge, and whether huge - tiny is
+ *	equal to huge for some floating point number "huge" and "tiny".
+ *		
+ * Special cases:
+ *	sqrt(+-0) = +-0 	... exact
+ *	sqrt(inf) = inf
+ *	sqrt(-ve) = NaN		... with invalid signal
+ *	sqrt(NaN) = NaN		... with invalid signal for signaling NaN
+ *
+ * Other methods : see the appended file at the end of the program below.

+Other methods  (use floating-point arithmetic)
+-------------
+(This is a copy of a drafted paper by Prof W. Kahan 
+and K.C. Ng, written in May, 1986)
+
+	Two algorithms are given here to implement sqrt(x) 
+	(IEEE double precision arithmetic) in software.
+	Both supply sqrt(x) correctly rounded. The first algorithm (in
+	Section A) uses newton iterations and involves four divisions.
+	The second one uses reciproot iterations to avoid division, but
+	requires more multiplications. Both algorithms need the ability
+	to chop results of arithmetic operations instead of round them, 
+	and the INEXACT flag to indicate when an arithmetic operation
+	is executed exactly with no roundoff error, all part of the 
+	standard (IEEE 754-1985). The ability to perform shift, add,
+	subtract and logical AND operations upon 32-bit words is needed
+	too, though not part of the standard.
+
+A.  sqrt(x) by Newton Iteration
+
+   (1)	Initial approximation
+
+	Let x0 and x1 be the leading and the trailing 32-bit words of
+	a floating point number x (in IEEE double format) respectively 
+
+	    1    11		     52				  ...widths
+	   ------------------------------------------------------
+	x: |s|	  e     |	      f				|
+	   ------------------------------------------------------
+	      msb    lsb  msb				      lsb ...order
+
+ 
+	     ------------------------  	     ------------------------
+	x0:  |s|   e    |    f1     |	 x1: |          f2           |
+	     ------------------------  	     ------------------------
+
+	By performing shifts and subtracts on x0 and x1 (both regarded
+	as integers), we obtain an 8-bit approximation of sqrt(x) as
+	follows.
+
+		k  := (x0>>1) + 0x1ff80000;
+		y0 := k - T1[31&(k>>15)].	... y ~ sqrt(x) to 8 bits
+	Here k is a 32-bit integer and T1[] is an integer array containing
+	correction terms. Now magically the floating value of y (y's
+	leading 32-bit word is y0, the value of its trailing word is 0)
+	approximates sqrt(x) to almost 8-bit.
+
+	Value of T1:
+	static int T1[32]= {
+	0,	1024,	3062,	5746,	9193,	13348,	18162,	23592,
+	29598,	36145,	43202,	50740,	58733,	67158,	75992,	85215,
+	83599,	71378,	60428,	50647,	41945,	34246,	27478,	21581,
+	16499,	12183,	8588,	5674,	3403,	1742,	661,	130,};
+
+    (2)	Iterative refinement
+
+	Apply Heron's rule three times to y, we have y approximates 
+	sqrt(x) to within 1 ulp (Unit in the Last Place):
+
+		y := (y+x/y)/2		... almost 17 sig. bits
+		y := (y+x/y)/2		... almost 35 sig. bits
+		y := y-(y-x/y)/2	... within 1 ulp
+
+
+	Remark 1.
+	    Another way to improve y to within 1 ulp is:
+
+		y := (y+x/y)		... almost 17 sig. bits to 2*sqrt(x)
+		y := y - 0x00100006	... almost 18 sig. bits to sqrt(x)
+
+				2
+			    (x-y )*y
+		y := y + 2* ----------	...within 1 ulp
+			       2
+			     3y  + x
+
+
+	This formula has one division fewer than the one above; however,
+	it requires more multiplications and additions. Also x must be
+	scaled in advance to avoid spurious overflow in evaluating the
+	expression 3y*y+x. Hence it is not recommended uless division
+	is slow. If division is very slow, then one should use the 
+	reciproot algorithm given in section B.
+
+    (3) Final adjustment
+
+	By twiddling y's last bit it is possible to force y to be 
+	correctly rounded according to the prevailing rounding mode
+	as follows. Let r and i be copies of the rounding mode and
+	inexact flag before entering the square root program. Also we
+	use the expression y+-ulp for the next representable floating
+	numbers (up and down) of y. Note that y+-ulp = either fixed
+	point y+-1, or multiply y by nextafter(1,+-inf) in chopped
+	mode.
+
+		I := FALSE;	... reset INEXACT flag I
+		R := RZ;	... set rounding mode to round-toward-zero
+		z := x/y;	... chopped quotient, possibly inexact
+		If(not I) then {	... if the quotient is exact
+		    if(z=y) {
+		        I := i;	 ... restore inexact flag
+		        R := r;  ... restore rounded mode
+		        return sqrt(x):=y.
+		    } else {
+			z := z - ulp;	... special rounding
+		    }
+		}
+		i := TRUE;		... sqrt(x) is inexact
+		If (r=RN) then z=z+ulp	... rounded-to-nearest
+		If (r=RP) then {	... round-toward-+inf
+		    y = y+ulp; z=z+ulp;
+		}
+		y := y+z;		... chopped sum
+		y0:=y0-0x00100000;	... y := y/2 is correctly rounded.
+	        I := i;	 		... restore inexact flag
+	        R := r;  		... restore rounded mode
+	        return sqrt(x):=y.
+		    
+    (4)	Special cases
+
+	Square root of +inf, +-0, or NaN is itself;
+	Square root of a negative number is NaN with invalid signal.
+
+
+B.  sqrt(x) by Reciproot Iteration
+
+   (1)	Initial approximation
+
+	Let x0 and x1 be the leading and the trailing 32-bit words of
+	a floating point number x (in IEEE double format) respectively
+	(see section A). By performing shifs and subtracts on x0 and y0,
+	we obtain a 7.8-bit approximation of 1/sqrt(x) as follows.
+
+	    k := 0x5fe80000 - (x0>>1);
+	    y0:= k - T2[63&(k>>14)].	... y ~ 1/sqrt(x) to 7.8 bits
+
+	Here k is a 32-bit integer and T2[] is an integer array 
+	containing correction terms. Now magically the floating
+	value of y (y's leading 32-bit word is y0, the value of
+	its trailing word y1 is set to zero) approximates 1/sqrt(x)
+	to almost 7.8-bit.
+
+	Value of T2:
+	static int T2[64]= {
+	0x1500,	0x2ef8,	0x4d67,	0x6b02,	0x87be,	0xa395,	0xbe7a,	0xd866,
+	0xf14a,	0x1091b,0x11fcd,0x13552,0x14999,0x15c98,0x16e34,0x17e5f,
+	0x18d03,0x19a01,0x1a545,0x1ae8a,0x1b5c4,0x1bb01,0x1bfde,0x1c28d,
+	0x1c2de,0x1c0db,0x1ba73,0x1b11c,0x1a4b5,0x1953d,0x18266,0x16be0,
+	0x1683e,0x179d8,0x18a4d,0x19992,0x1a789,0x1b445,0x1bf61,0x1c989,
+	0x1d16d,0x1d77b,0x1dddf,0x1e2ad,0x1e5bf,0x1e6e8,0x1e654,0x1e3cd,
+	0x1df2a,0x1d635,0x1cb16,0x1be2c,0x1ae4e,0x19bde,0x1868e,0x16e2e,
+	0x1527f,0x1334a,0x11051,0xe951,	0xbe01,	0x8e0d,	0x5924,	0x1edd,};
+
+    (2)	Iterative refinement
+
+	Apply Reciproot iteration three times to y and multiply the
+	result by x to get an approximation z that matches sqrt(x)
+	to about 1 ulp. To be exact, we will have 
+		-1ulp < sqrt(x)-z<1.0625ulp.
+	
+	... set rounding mode to Round-to-nearest
+	   y := y*(1.5-0.5*x*y*y)	... almost 15 sig. bits to 1/sqrt(x)
+	   y := y*((1.5-2^-30)+0.5*x*y*y)... about 29 sig. bits to 1/sqrt(x)
+	... special arrangement for better accuracy
+	   z := x*y			... 29 bits to sqrt(x), with z*y<1
+	   z := z + 0.5*z*(1-z*y)	... about 1 ulp to sqrt(x)
+
+	Remark 2. The constant 1.5-2^-30 is chosen to bias the error so that
+	(a) the term z*y in the final iteration is always less than 1; 
+	(b) the error in the final result is biased upward so that
+		-1 ulp < sqrt(x) - z < 1.0625 ulp
+	    instead of |sqrt(x)-z|<1.03125ulp.
+
+    (3)	Final adjustment
+
+	By twiddling y's last bit it is possible to force y to be 
+	correctly rounded according to the prevailing rounding mode
+	as follows. Let r and i be copies of the rounding mode and
+	inexact flag before entering the square root program. Also we
+	use the expression y+-ulp for the next representable floating
+	numbers (up and down) of y. Note that y+-ulp = either fixed
+	point y+-1, or multiply y by nextafter(1,+-inf) in chopped
+	mode.
+
+	R := RZ;		... set rounding mode to round-toward-zero
+	switch(r) {
+	    case RN:		... round-to-nearest
+	       if(x<= z*(z-ulp)...chopped) z = z - ulp; else
+	       if(x<= z*(z+ulp)...chopped) z = z; else z = z+ulp;
+	       break;
+	    case RZ:case RM:	... round-to-zero or round-to--inf
+	       R:=RP;		... reset rounding mod to round-to-+inf
+	       if(x<z*z ... rounded up) z = z - ulp; else
+	       if(x>=(z+ulp)*(z+ulp) ...rounded up) z = z+ulp;
+	       break;
+	    case RP:		... round-to-+inf
+	       if(x>(z+ulp)*(z+ulp)...chopped) z = z+2*ulp; else
+	       if(x>z*z ...chopped) z = z+ulp;
+	       break;
+	}
+
+	Remark 3. The above comparisons can be done in fixed point. For
+	example, to compare x and w=z*z chopped, it suffices to compare
+	x1 and w1 (the trailing parts of x and w), regarding them as
+	two's complement integers.
+
+	...Is z an exact square root?
+	To determine whether z is an exact square root of x, let z1 be the
+	trailing part of z, and also let x0 and x1 be the leading and
+	trailing parts of x.
+
+	If ((z1&0x03ffffff)!=0)	... not exact if trailing 26 bits of z!=0
+	    I := 1;		... Raise Inexact flag: z is not exact
+	else {
+	    j := 1 - [(x0>>20)&1]	... j = logb(x) mod 2
+	    k := z1 >> 26;		... get z's 25-th and 26-th 
+					    fraction bits
+	    I := i or (k&j) or ((k&(j+j+1))!=(x1&3));
+	}
+	R:= r		... restore rounded mode
+	return sqrt(x):=z.
+
+	If multiplication is cheaper then the foregoing red tape, the 
+	Inexact flag can be evaluated by
+
+	    I := i;
+	    I := (z*z!=x) or I.
+
+	Note that z*z can overwrite I; this value must be sensed if it is 
+	True.
+
+	Remark 4. If z*z = x exactly, then bit 25 to bit 0 of z1 must be
+	zero.
+
+		    --------------------
+		z1: |        f2        | 
+		    --------------------
+		bit 31		   bit 0
+
+	Further more, bit 27 and 26 of z1, bit 0 and 1 of x1, and the odd
+	or even of logb(x) have the following relations:
+
+	-------------------------------------------------
+	bit 27,26 of z1		bit 1,0 of x1	logb(x)

+ * The method is to compute the integer (mod 8) and fraction parts of 
+ * (2/pi)*x without doing the full multiplication. In general we
+ * skip the part of the product that are known to be a huge integer (
+ * more accurately, = 0 mod 8 ). Thus the number of operations are
+ * independent of the exponent of the input.
+ *
+ * (2/pi) is represented by an array of 24-bit integers in ipio2[].
+ *
+ * Input parameters:
+ * 	x[]	The input value (must be positive) is broken into nx 
+ *		pieces of 24-bit integers in double precision format.
+ *		x[i] will be the i-th 24 bit of x. The scaled exponent 
+ *		of x[0] is given in input parameter e0 (i.e., x[0]*2^e0 
+ *		match x's up to 24 bits.
+ *
+ *		Example of breaking a double positive z into x[0]+x[1]+x[2]:
+ *			e0 = ilogb(z)-23
+ *			z  = scalbn(z,-e0)
+ *		for i = 0,1,2
+ *			x[i] = floor(z)
+ *			z    = (z-x[i])*2**24
+ *
+ *
+ *	y[]	ouput result in an array of double precision numbers.
+ *		The dimension of y[] is:
+ *			24-bit  precision	1
+ *			53-bit  precision	2
+ *			64-bit  precision	2
+ *			113-bit precision	3
+ *		The actual value is the sum of them. Thus for 113-bit
+ *		precison, one may have to do something like:
+ *
+ *		long double t,w,r_head, r_tail;
+ *		t = (long double)y[2] + (long double)y[1];
+ *		w = (long double)y[0];
+ *		r_head = t+w;
+ *		r_tail = w - (r_head - t);
+ *
+ *	e0	The exponent of x[0]
+ *
+ *	nx	dimension of x[]
+ *
+ *  	prec	an integer indicating the precision:
+ *			0	24  bits (single)
+ *			1	53  bits (double)
+ *			2	64  bits (extended)
+ *			3	113 bits (quad)
+ *
+ *	ipio2[]
+ *		integer array, contains the (24*i)-th to (24*i+23)-th 
+ *		bit of 2/pi after binary point. The corresponding 
+ *		floating value is
+ *
+ *			ipio2[i] * 2^(-24(i+1)).
+ *
+ * External function:
+ *	double scalbn(), floor();
+ *
+ *
+ * Here is the description of some local variables:
+ *
+ * 	jk	jk+1 is the initial number of terms of ipio2[] needed
+ *		in the computation. The recommended value is 2,3,4,
+ *		6 for single, double, extended,and quad.
+ *
+ * 	jz	local integer variable indicating the number of 
+ *		terms of ipio2[] used. 
+ *
+ *	jx	nx - 1
+ *
+ *	jv	index for pointing to the suitable ipio2[] for the
+ *		computation. In general, we want
+ *			( 2^e0*x[0] * ipio2[jv-1]*2^(-24jv) )/8
+ *		is an integer. Thus
+ *			e0-3-24*jv >= 0 or (e0-3)/24 >= jv
+ *		Hence jv = max(0,(e0-3)/24).
+ *
+ *	jp	jp+1 is the number of terms in PIo2[] needed, jp = jk.
+ *
+ * 	q[]	double array with integral value, representing the
+ *		24-bits chunk of the product of x and 2/pi.
+ *
+ *	q0	the corresponding exponent of q[0]. Note that the
+ *		exponent for q[i] would be q0-24*i.
+ *
+ *	PIo2[]	double precision array, obtained by cutting pi/2
+ *		into 24 bits chunks. 
+ *
+ *	f[]	ipio2[] in floating point 
+ *
+ *	iq[]	integer array by breaking up q[] in 24-bits chunk.
+ *
+ *	fq[]	final product of x*(2/pi) in fq[0],..,fq[jk]

+ * Method
+ *   1. Reduce x to positive by atan(x) = -atan(-x).
+ *   2. According to the integer k=4t+0.25 chopped, t=x, the argument
+ *      is further reduced to one of the following intervals and the
+ *      arctangent of t is evaluated by the corresponding formula:
+ *
+ *      [0,7/16]      atan(x) = t-t^3*(a1+t^2*(a2+...(a10+t^2*a11)...)
+ *      [7/16,11/16]  atan(x) = atan(1/2) + atan( (t-0.5)/(1+t/2) )
+ *      [11/16.19/16] atan(x) = atan( 1 ) + atan( (t-1)/(1+t) )
+ *      [19/16,39/16] atan(x) = atan(3/2) + atan( (t-1.5)/(1+1.5t) )
+ *      [39/16,INF]   atan(x) = atan(INF) + atan( -1/t )
+ *

+/* expm1(x)
+ * Returns exp(x)-1, the exponential of x minus 1.
+ *
+ * Method
+ *   1. Argument reduction:
+ *	Given x, find r and integer k such that
+ *
+ *               x = k*ln2 + r,  |r| <= 0.5*ln2 ~ 0.34658
+ *
+ *      Here a correction term c will be computed to compensate
+ *	the error in r when rounded to a floating-point number.
+ *
+ *   2. Approximating expm1(r) by a special rational function on
+ *	the interval [0,0.34658]:
+ *	Since
+ *	    r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 - r^4/360 + ...
+ *	we define R1(r*r) by
+ *	    r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 * R1(r*r)
+ *	That is,
+ *	    R1(r**2) = 6/r *((exp(r)+1)/(exp(r)-1) - 2/r)
+ *		     = 6/r * ( 1 + 2.0*(1/(exp(r)-1) - 1/r))
+ *		     = 1 - r^2/60 + r^4/2520 - r^6/100800 + ...
+ *      We use a special Reme algorithm on [0,0.347] to generate
+ * 	a polynomial of degree 5 in r*r to approximate R1. The
+ *	maximum error of this polynomial approximation is bounded
+ *	by 2**-61. In other words,
+ *	    R1(z) ~ 1.0 + Q1*z + Q2*z**2 + Q3*z**3 + Q4*z**4 + Q5*z**5
+ *	where 	Q1  =  -1.6666666666666567384E-2,
+ * 		Q2  =   3.9682539681370365873E-4,
+ * 		Q3  =  -9.9206344733435987357E-6,
+ * 		Q4  =   2.5051361420808517002E-7,
+ * 		Q5  =  -6.2843505682382617102E-9;
+ *  	(where z=r*r, and the values of Q1 to Q5 are listed below)
+ *	with error bounded by
+ *	    |                  5           |     -61
+ *	    | 1.0+Q1*z+...+Q5*z   -  R1(z) | <= 2
+ *	    |                              |
+ *
+ *	expm1(r) = exp(r)-1 is then computed by the following
+ * 	specific way which minimize the accumulation rounding error:
+ *			       2     3
+ *			      r     r    [ 3 - (R1 + R1*r/2)  ]
+ *	      expm1(r) = r + --- + --- * [--------------------]
+ *		              2     2    [ 6 - r*(3 - R1*r/2) ]
+ *
+ *	To compensate the error in the argument reduction, we use
+ *		expm1(r+c) = expm1(r) + c + expm1(r)*c
+ *			   ~ expm1(r) + c + r*c
+ *	Thus c+r*c will be added in as the correction terms for
+ *	expm1(r+c). Now rearrange the term to avoid optimization
+ * 	screw up:
+ *		        (      2                                    2 )
+ *		        ({  ( r    [ R1 -  (3 - R1*r/2) ]  )  }    r  )
+ *	 expm1(r+c)~r - ({r*(--- * [--------------------]-c)-c} - --- )
+ *	                ({  ( 2    [ 6 - r*(3 - R1*r/2) ]  )  }    2  )
+ *                      (                                             )
+ *
+ *		   = r - E
+ *   3. Scale back to obtain expm1(x):
+ *	From step 1, we have
+ *	   expm1(x) = either 2^k*[expm1(r)+1] - 1
+ *		    = or     2^k*[expm1(r) + (1-2^-k)]
+ *   4. Implementation notes:
+ *	(A). To save one multiplication, we scale the coefficient Qi
+ *	     to Qi*2^i, and replace z by (x^2)/2.
+ *	(B). To achieve maximum accuracy, we compute expm1(x) by
+ *	  (i)   if x < -56*ln2, return -1.0, (raise inexact if x!=inf)
+ *	  (ii)  if k=0, return r-E
+ *	  (iii) if k=-1, return 0.5*(r-E)-0.5
+ *        (iv)	if k=1 if r < -0.25, return 2*((r+0.5)- E)
+ *	       	       else	     return  1.0+2.0*(r-E);
+ *	  (v)   if (k<-2||k>56) return 2^k(1-(E-r)) - 1 (or exp(x)-1)
+ *	  (vi)  if k <= 20, return 2^k((1-2^-k)-(E-r)), else
+ *	  (vii) return 2^k(1-((E+2^-k)-r))
+ *
+ * Special cases:
+ *	expm1(INF) is INF, expm1(NaN) is NaN;
+ *	expm1(-INF) is -1, and
+ *	for finite argument, only expm1(0)=0 is exact.
+ *
+ * Accuracy:
+ *	according to an error analysis, the error is always less than
+ *	1 ulp (unit in the last place).
+ *
+ * Misc. info.
+ *	For IEEE double
+ *	    if x >  7.09782712893383973096e+02 then expm1(x) overflow
+ *
+ * Constants:
+ * The hexadecimal values are the intended ones for the following
+ * constants. The decimal values may be used, provided that the
+ * compiler will convert from decimal to binary accurately enough
+ * to produce the hexadecimal values shown.

+/* double log1p(double x)
+ *
+ * Method :
+ *   1. Argument Reduction: find k and f such that
+ *			1+x = 2^k * (1+f),
+ *	   where  sqrt(2)/2 < 1+f < sqrt(2) .
+ *
+ *      Note. If k=0, then f=x is exact. However, if k!=0, then f
+ *	may not be representable exactly. In that case, a correction
+ *	term is need. Let u=1+x rounded. Let c = (1+x)-u, then
+ *	log(1+x) - log(u) ~ c/u. Thus, we proceed to compute log(u),
+ *	and add back the correction term c/u.
+ *	(Note: when x > 2**53, one can simply return log(x))
+ *
+ *   2. Approximation of log1p(f).
+ *	Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
+ *		 = 2s + 2/3 s**3 + 2/5 s**5 + .....,
+ *	     	 = 2s + s*R
+ *      We use a special Reme algorithm on [0,0.1716] to generate
+ * 	a polynomial of degree 14 to approximate R The maximum error
+ *	of this polynomial approximation is bounded by 2**-58.45. In
+ *	other words,
+ *		        2      4      6      8      10      12      14
+ *	    R(z) ~ Lp1*s +Lp2*s +Lp3*s +Lp4*s +Lp5*s  +Lp6*s  +Lp7*s
+ *  	(the values of Lp1 to Lp7 are listed in the program)
+ *	and
+ *	    |      2          14          |     -58.45
+ *	    | Lp1*s +...+Lp7*s    -  R(z) | <= 2
+ *	    |                             |
+ *	Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
+ *	In order to guarantee error in log below 1ulp, we compute log
+ *	by
+ *		log1p(f) = f - (hfsq - s*(hfsq+R)).
+ *
+ *	3. Finally, log1p(x) = k*ln2 + log1p(f).
+ *		 	     = k*ln2_hi+(f-(hfsq-(s*(hfsq+R)+k*ln2_lo)))
+ *	   Here ln2 is split into two floating point number:
+ *			ln2_hi + ln2_lo,
+ *	   where n*ln2_hi is always exact for |n| < 2000.
+ *
+ * Special cases:
+ *	log1p(x) is NaN with signal if x < -1 (including -INF) ;
+ *	log1p(+INF) is +INF; log1p(-1) is -INF with signal;
+ *	log1p(NaN) is that NaN with no signal.
+ *
+ * Accuracy:
+ *	according to an error analysis, the error is always less than
+ *	1 ulp (unit in the last place).
+ *
+ * Constants:
+ * The hexadecimal values are the intended ones for the following
+ * constants. The decimal values may be used, provided that the
+ * compiler will convert from decimal to binary accurately enough
+ * to produce the hexadecimal values shown.
+ *
+ * Note: Assuming log() return accurate answer, the following
+ * 	 algorithm can be used to compute log1p(x) to within a few ULP:
+ *
+ *		u = 1+x;
+ *		if(u==1.0) return x ; else
+ *			   return log(u)*(x/(u-1.0));
+ *
+ *	 See HP-15C Advanced Functions Handbook, p.193.

+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
