  92
  93         * src/atomic_ops/generalize-small.template (AO_XSIZE_fetch_and_add):

  96
  97 2013-03-29  Ivan Maidanski <ivmai@mail.ru>

 101         AO_test_and_set_full,
 102         AO_compare_and_swap_full): Use "+m" asm constraint for *addr instead
 103         of "=m" (because the value pointed by addr is read and written by the
 104         code).
 105
 106 2013-03-13  Ivan Maidanski <ivmai@mail.ru>
 107
 108         * src/atomic_ops/sysdeps/gcc/alpha.h (AO_compare_and_swap): Use "+m"

 111
 112 2013-03-12  Ivan Maidanski <ivmai@mail.ru>
 113
 114         * src/atomic_ops/sysdeps/gcc/mips.h (AO_compare_and_swap): Use "+m"
 115         asm constraint for *addr instead of "+R" (the letter is unsupported
 116         by clang3.1 resulting in "invalid output constraint in asm" error).
 117
 118 2013-02-14  Ivan Maidanski <ivmai@mail.ru>
 119
 120         * src/atomic_ops/sysdeps/gcc/arm.h: Do not include read_ordered.h
 121         (because load_acquire should contain a DMB instruction in a multi-core
 122         case, new load_acquire/read primitives implementation is generalized
 123         using nop_full/read which either contain a DMB instruction, or is just
 124         a compiler barrier for uniprocessor).
 125         * src/atomic_ops/sysdeps/armcc/arm_v6.h: Likewise.
 126         * src/atomic_ops/sysdeps/msftc/arm.h: Likewise.

 131         barrier (similar as in atomic_ops.h).
 132         * doc/README.txt (_release_read): Remove information about
 133         non-existing barrier.
 134

 141         * src/atomic_ops/sysdeps/ao_t_is_int.h
 142         (AO_int_load_acquire, AO_int_fetch_and_add_full,
 143         AO_int_fetch_and_add1_acquire, AO_int_fetch_and_add1_release,
 144         AO_int_fetch_and_sub1_acquire, AO_int_fetch_and_sub1_release): Cast
 145         result to unsigned int instead of signed int.

 147 2013-01-13  Ivan Maidanski <ivmai@mail.ru>
 148
 149         * src/atomic_ops/sysdeps/gcc/s390.h: Move include of
 150         ordered_except_wr.h down to be after all_aligned_atomic_load_store.h
 151         inclusion (since the latter defines AO_X_load/store primitives used by
 152         the former header).
 153
 154 2013-01-13  Ivan Maidanski <ivmai@mail.ru>
 155
 156         * src/atomic_ops/sysdeps/msftc/arm.h: Fix a typo in comment (about
 157         SWP).
 158
 159 2013-01-07  Ivan Maidanski <ivmai@mail.ru>
 160
 161         * src/atomic_ops/sysdeps/read_ordered.h (AO_char_load_read,
 162         AO_short_load_read, AO_int_load_read): Change return type (and the
 163         type of "result" local variable) from AO_t to the type matching the
 164         name of the function (i.e., unsigned char/short/int, respectively).
 165
 166 2013-01-06  Ivan Maidanski <ivmai@mail.ru>
 167
 168         * src/atomic_ops/sysdeps/armcc/arm_v6.h (AO_nop_full): Insert
 169         AO_compiler_barrier for AO_UNIPROCESSOR case.

 179
 180         * src/atomic_ops/Makefile.am (BUILT_SOURCES): Define to force
 181         regeneration of generalize-small.h (if the corresponding
 182         source template is changed) before compilation of .c files (that use
 183         atomic_ops.h).
 184
 185 2013-01-02  Ivan Maidanski <ivmai@mail.ru>
 186
 187         * src/atomic_ops/generalize-small.template (AO_XSIZE_fetch_and_add):

 200
 201 2012-10-09  Ivan Maidanski <ivmai@mail.ru>
 202
 203         * tests/test_stack.c (run_one_test): Change type of "index" local
 204         variable from long to int to match printf format specifier (when
 205         VERBOSE defined); cast from "arg" pointer to integer via size_t (to
 206         avoid 64-bit compiler warning).
 207
 208 2012-10-08  Ivan Maidanski <ivmai@mail.ru>
 209
 210         * src/atomic_ops/sysdeps/gcc/x86.h (AO_double_compare_and_swap_full):

 234
 235         * src/atomic_ops_stack.c (dummy): Define as static (to make symbol
 236         without AO_ prefix visible only within this file); initialize to 1

 241
 242         * src/atomic_ops.h: Fix 'load' primitive name in comment (replace

 253
 254         * src/atomic_ops/sysdeps/standard_ao_double_t.h (double_ptr_storage):
 255         Define as "unsigned long long" instead of __m128 for gcc/x32 (i.e.,
 256         ILP32 on x86_64); update and reformat comment.

 279         * src/atomic_ops.h: Include gcc/x86.h instead of gcc/x86_64.h if
 280         gcc/x32 (i.e., GCC (or Intel compiler), __x86_64__ is defined, and
 281         __ILP32__ is defined) to have AO_compare_double_and_swap_double_full
 282         defined properly (based on cmpxchg8b); explicitly define
 283         AO_USE_PENTIUM4_INSTRS for gcc/x32.
 284         * src/atomic_ops/sysdeps/gcc/x86_64.h: Remove ILP32-specific code

 313         preserved), so that the whole code could also work even if EBX points
 314         to memory operand (e.g., in Clang); test __PIC__ using ifdef (instead
 315         of "if"); update comments; reformat code.

 340         that do not recognize 'D' as a valid register specification; update
 341         comment.

1726 2005-03-21  Hans Boehm <Hans.Boehm@hp.com>
1727         Fix various acquire_release_volatile.h files to reflect the fact
1728         that both icc and gcc seem to reorder ordinary memory accesses around
1729         volatile accesses early in the compilation. Modify the acquire

1763 2004-10 Hans Boehm <Hans.Boehm@hp.com>
1764         More work on char, short, int sized data.  Add both
1765         compare_double_and_swap_double and compare_and_swap_double.
1766         Typically each platform will provide at most one of these.
1767
1768 2004-07-02  Ranko Zivojnovic
1769         Replace both instances of AO_HAVE_NOP_FULL with AO_HAVE_nop_full.

1785         for atomic_ops for VC++/Windows/X86 and HP/UX with the HP
1786         compiler on PA_RISC and IA64.
1787

1802
1803
1804 Started sometime after version 0.4 release.  Currently the format is
1805 informal.  Eventually should become more GNU-like.
