With atomic fastbins the checks performed can race with concurrent
modifications of the arena. If we detect a problem re-do the test
after getting the lock.
The following patch fixes catomic_compare_and_exchange_*_rel definitions
(which were never used and weren't correct) and uses
catomic_compare_and_exchange_val_rel in _int_free. Comparing to the
pre-2009-07-02 --enable-experimental-malloc state the generated code should
be identical on all arches other than ppc/ppc64 and on ppc/ppc64 should use
lwsync instead of isync barrier.

same rule which qsort.c had problems with.
2002-01-27 Paul Eggert <eggert@twinsun.com>
* stdlib/qsort.c (_quicksort): Do not apply the comparison function
to a pivot element that lies outside the array to be sorted, as
ISO C99 requires that the comparison function be called only with
addresses of array elements [PR libc/2880].
2001-08-11 Ulrich Drepper <drepper@redhat.com>
* malloc/malloc.c (ptmalloc_init): Don't call getenv five times.
Instead use new function next_env_entry which iterates over the

only if consider_profiling is != 0, not if _dl_profile != NULL.

Now returns pointer to first character set "LD_".
* elf/rtld.c (process_envvars): Adjust for change above.
* sysdeps/unix/sysv/linux/dl-librecon.h (EXTRA_LD_ENVVARS): Likewise.
* sysdeps/unix/sysv/linux/i386/dl-librecon.h (EXTRA_LD_ENVVARS):
Likewise.

* libio/filedoalloc.c (_IO_file_doallocate): Use DEV_TTY_P if
available to determine whether descriptor is for tty before
calling isatty.
* sysdeps/unix/sysv/linux/device-nrs.h: Define DEV_TTY_P.
* sysdeps/generic/device-nrs.h: Likewise.
2001-07-06 Paul Eggert <eggert@twinsun.com>
* manual/argp.texi: Remove ignored LGPL copyright notice; it's
not appropriate for documentation anyway.
* manual/libc-texinfo.sh: "Library General Public License" ->
"Lesser General Public License".
2001-07-06 Andreas Jaeger <aj@suse.de>
* All files under GPL/LGPL version 2: Place under LGPL version
2.1.
2001-06-22 Jakub Jelinek <jakub@redhat.com>
* posix/regex.c (regex_compile, re_match_2_internal): Fix comment
typos.
2001-06-01 Wolfram Gloger <wg@malloc.de>
* malloc/malloc.c (malloc_atfork, free_atfork): Use a unique value
ATFORK_ARENA_PTR, not 0, for the thread-specific arena pointer
when malloc_atfork is in use.
2001-04-25 Ulrich Drepper <drepper@redhat.com>
* malloc/malloc.c: Allow MALLOC_ALIGNMENT to be defined on the
compiler command line.
* sysdeps/hppa/Makefile: Add -DMALLOC_ALIGNMENT=16 to compiler
command line for malloc.c.
2001-02-14 Wolfram Gloger <wg@malloc.de>
* malloc/malloc.c (new_heap): When allocating large chunk aligned
to HEAP_MAX_SIZE, prefer one with lower address, to avoid `holes'
between the heaps.
2001-01-21 Franz Sirl <Franz.Sirl-kernel@lauterbach.com>
* sysdeps/unix/sysv/linux/powerpc/mmap64.c: Correctly mask offset.
2001-01-21 Ulrich Drepper <drepper@redhat.com>

variables.
2000-12-28 Wolfram Gloger <wg@malloc.de>

destination overlap. Assume dest is always below source if
overlapping.
2000-08-31 Ulrich Drepper <drepper@redhat.com>
* malloc/malloc.c (ptmalloc_init): Optimize a bit by not calling
__secure_getenv. Instead test __libc_enable_secure once.
* io/pwd.c (main): Provide a good example, use *_unlocked function.
2000-07-21 Wolfram Gloger <wg@malloc.de>
* malloc/malloc.c (chunk_alloc): Try mmap_chunk() for smaller
allocations only if a non-main arena cannot be extended.
* sysdeps/powerpc/bp-asm.h (DISCARD_BOUNDS): Rename from
UNCHECK_BOUNDS.
set_inuse_bit_at_offset, clear_inuse_bit_at_offset, set_foot):
Define in terms of chunk_at_offset.
(inuse, set_inuse, clear_inuse): Define in terms of next_chunk.
(next_bin, prev_bin): offset by size of real array elements.
(chunk_align): Make `m' a scalar, since that's how it's used.
* malloc/malloc.c (next_chunk, prev_chunk, inuse_bit_at_offset,
set_inuse_bit_at_offset, clear_inuse_bit_at_offset, set_foot):
Define in terms of chunk_at_offset.
(inuse, set_inuse, clear_inuse): Define in terms of next_chunk.
(next_bin, prev_bin): offset by size of real array elements.

2000-07-18 Kaz Kylheku <kaz@ashi.footprints.net>
* spinlock.c (__pthread_alt_lock, __pthread_alt_timedlock): Fixed
bug whereby thr field of waitnode structure would not be correctly
set unless a null self pointer is passed to the functions.
Eliminated redundant calls to thread_self().
2000-07-17 Bruno Haible <haible@clisp.cons.org>
* iconv/gconv_open.c (__gconv_open): Initialize the __data
field of struct __gconv_trans_data differently. Don't pass NULL to
trans_init_fct. Simplify list append operation.

* intl/dcigettext.c (dcigettext): Call plural_eval on all platforms,
not only those having tsearch.

* locale/langinfo.h: Add placeholder values in enum for removed
LC_CTYPE entries.
2000-07-17 Jakub Jelinek <jakub@redhat.com>

chain if the PHDR check fails.
2000-07-17 Mark Kettenis <kettenis@gnu.org>

between numeric addresses and hostnames.
2000-07-17 Wolfram Gloger <wg@malloc.de>

i.e. if n_mmaps_max>0.

values to remove possible clash with other AI_* constants.
(AI_PASSIVE, AI_CANONNAME, AI_NUMERICHOST): Define as
