  74
  75         * src/atomic_ops/sysdeps/gcc/arm.h
  76         (AO_compare_double_and_swap_double): Do not define for
  77         pre-Clang3.3 (since the latter does not allocate register pairs for
  78         LDREXD/STREXD instructions properly); add comment.
  79
  80 2013-08-17  Ivan Maidanski <ivmai@mail.ru>

  87
  88         * src/atomic_ops/sysdeps/gcc/arm.h
  89         (AO_compare_double_and_swap_double): Specify that LDREXD and STREXD use
  90         2 adjacent registers (thus preventing Clang3.3 from register allocation
  91         failures leading to "registers may not be the same" or
  92         "even register required" GAS errors).
  93
  94 2013-07-30  Ivan Maidanski <ivmai@mail.ru>
  95

 105
 106         * src/atomic_ops/generalize-small.template (AO_XSIZE_fetch_and_add):

 108         * src/atomic_ops/generalize-small.h: Regenerate.
 109
 110 2013-03-29  Ivan Maidanski <ivmai@mail.ru>
 111
 112         * src/atomic_ops/sysdeps/sunc/x86.h (AO_fetch_and_add_full,
 113         AO_char_fetch_and_add_full, AO_short_fetch_and_add_full, AO_or_full,
 114         AO_test_and_set_full,
 115         AO_compare_and_swap_full): Use "+m" asm constraint for *addr instead
 116         of "=m" (because the value pointed by addr is read and written by the
 117         code).
 118
 119 2013-03-13  Ivan Maidanski <ivmai@mail.ru>
 120
 121         * src/atomic_ops/sysdeps/gcc/alpha.h (AO_compare_and_swap): Use "+m"
 122         asm constraint for *addr instead of "=m" (because the value pointed by
 123         addr is read and written by the code).
 124
 125 2013-03-12  Ivan Maidanski <ivmai@mail.ru>
 126
 127         * src/atomic_ops/sysdeps/gcc/mips.h (AO_compare_and_swap): Use "+m"
 128         asm constraint for *addr instead of "+R" (the letter is unsupported
 129         by clang3.1 resulting in "invalid output constraint in asm" error).
 130
 131 2013-02-14  Ivan Maidanski <ivmai@mail.ru>
 132
 133         * src/atomic_ops/sysdeps/gcc/arm.h: Do not include read_ordered.h
 134         (because load_acquire should contain a DMB instruction in a multi-core
 135         case, new load_acquire/read primitives implementation is generalized
 136         using nop_full/read which either contain a DMB instruction, or is just
 137         a compiler barrier for uniprocessor).
 138         * src/atomic_ops/sysdeps/armcc/arm_v6.h: Likewise.
 139         * src/atomic_ops/sysdeps/msftc/arm.h: Likewise.

 141 2013-01-15  Ivan Maidanski <ivmai@mail.ru>
 142
 143         * doc/README.txt (_acquire_read): Add information about memory
 144         barrier (similar as in atomic_ops.h).
 145         * doc/README.txt (_release_read): Remove information about
 146         non-existing barrier.
 147
 148 2013-01-14  Ivan Maidanski <ivmai@mail.ru>

 153
 154         * src/atomic_ops/sysdeps/ao_t_is_int.h
 155         (AO_int_load_acquire, AO_int_fetch_and_add_full,
 156         AO_int_fetch_and_add1_acquire, AO_int_fetch_and_add1_release,
 157         AO_int_fetch_and_sub1_acquire, AO_int_fetch_and_sub1_release): Cast
 158         result to unsigned int instead of signed int.
 159
 160 2013-01-13  Ivan Maidanski <ivmai@mail.ru>
 161
 162         * src/atomic_ops/sysdeps/gcc/s390.h: Move include of
 163         ordered_except_wr.h down to be after all_aligned_atomic_load_store.h
 164         inclusion (since the latter defines AO_X_load/store primitives used by
 165         the former header).
 166
 167 2013-01-13  Ivan Maidanski <ivmai@mail.ru>
 168
 169         * src/atomic_ops/sysdeps/msftc/arm.h: Fix a typo in comment (about
 170         SWP).
 171
 172 2013-01-07  Ivan Maidanski <ivmai@mail.ru>
 173
 174         * src/atomic_ops/sysdeps/read_ordered.h (AO_char_load_read,
 175         AO_short_load_read, AO_int_load_read): Change return type (and the
 176         type of "result" local variable) from AO_t to the type matching the
 177         name of the function (i.e., unsigned char/short/int, respectively).
 178
 179 2013-01-06  Ivan Maidanski <ivmai@mail.ru>
 180
 181         * src/atomic_ops/sysdeps/armcc/arm_v6.h (AO_nop_full): Insert
 182         AO_compiler_barrier for AO_UNIPROCESSOR case.
 183         * src/atomic_ops/sysdeps/gcc/arm.h (AO_nop_full): Likewise.

 191 2013-01-04  Ivan Maidanski <ivmai@mail.ru>
 192
 193         * src/atomic_ops/Makefile.am (BUILT_SOURCES): Define to force
 194         regeneration of generalize-small.h (if the corresponding
 195         source template is changed) before compilation of .c files (that use
 196         atomic_ops.h).
 197
 198 2013-01-02  Ivan Maidanski <ivmai@mail.ru>
 199
 200         * src/atomic_ops/generalize-small.template (AO_XSIZE_fetch_and_add):
 201         Add missed definition based on CAS.
 202         * src/atomic_ops/generalize-small.h: Regenerate.
 203
 204 2013-01-02  Ivan Maidanski <ivmai@mail.ru>
 205
 206         * src/atomic_ops/generalize-small.template (AO_XSIZE_load): Move
 207         definition (which is based on AO_XSIZE_load_acquire) down to be after

 213
 214 2012-10-09  Ivan Maidanski <ivmai@mail.ru>
 215
 216         * tests/test_stack.c (run_one_test): Change type of "index" local
 217         variable from long to int to match printf format specifier (when
 218         VERBOSE defined); cast from "arg" pointer to integer via size_t (to
 219         avoid 64-bit compiler warning).
 220
 221 2012-10-08  Ivan Maidanski <ivmai@mail.ru>
 222
 223         * src/atomic_ops/sysdeps/gcc/x86.h (AO_double_compare_and_swap_full):

 232
 233 2012-10-05  Ivan Maidanski <ivmai@mail.ru>

 241         Sleep) for the case of 'n' argument in range between 12 and 21,

 243         * src/atomic_ops_stack.c (AO_pause): Evaluate 'msecs' value using the
 244         same algorithm as in atomic_ops.c (Win32 only).

 247
 248         * src/atomic_ops_stack.c (dummy): Define as static (to make symbol
 249         without AO_ prefix visible only within this file); initialize to 1
 250         (same as in atomic_ops.c, so that AO_spin would never really alter
 251         its value).
 252
 253 2012-10-02  Ivan Maidanski <ivmai@mail.ru>
 254
 255         * src/atomic_ops.h: Fix 'load' primitive name in comment (replace

 266
 267         * src/atomic_ops/sysdeps/standard_ao_double_t.h (double_ptr_storage):
 268         Define as "unsigned long long" instead of __m128 for gcc/x32 (i.e.,
 269         ILP32 on x86_64); update and reformat comment.

 292         * src/atomic_ops.h: Include gcc/x86.h instead of gcc/x86_64.h if
 293         gcc/x32 (i.e., GCC (or Intel compiler), __x86_64__ is defined, and
 294         __ILP32__ is defined) to have AO_compare_double_and_swap_double_full
 295         defined properly (based on cmpxchg8b); explicitly define
 296         AO_USE_PENTIUM4_INSTRS for gcc/x32.
 297         * src/atomic_ops/sysdeps/gcc/x86_64.h: Remove ILP32-specific code

 325         saving memory operand address to a register (edi which is manually
 326         preserved), so that the whole code could also work even if EBX points
 327         to memory operand (e.g., in Clang); test __PIC__ using ifdef (instead
 328         of "if"); update comments; reformat code.

 351         "new_val1" argument in PIC mode only for GCC 4.3+ to workaround
 352         a problem with older compiler versions (e.g., GCC 4.2.1 [FreeBSD])
 353         that do not recognize 'D' as a valid register specification; update
 354         comment.
 355

1739 2005-03-21  Hans Boehm <Hans.Boehm@hp.com>
1740         Fix various acquire_release_volatile.h files to reflect the fact
1741         that both icc and gcc seem to reorder ordinary memory accesses around
1742         volatile accesses early in the compilation. Modify the acquire

1775
1776 2004-10 Hans Boehm <Hans.Boehm@hp.com>
1777         More work on char, short, int sized data.  Add both
1778         compare_double_and_swap_double and compare_and_swap_double.
1779         Typically each platform will provide at most one of these.
1780
1781 2004-07-02  Ranko Zivojnovic
1782         Replace both instances of AO_HAVE_NOP_FULL with AO_HAVE_nop_full.

1797         Makefile.atomic_ops.msft, atomic_ops.h: Add initial support
1798         for atomic_ops for VC++/Windows/X86 and HP/UX with the HP
1799         compiler on PA_RISC and IA64.
1800

1802
1803         * many: Install under "atomic_ops" instead of "ao".

1813         AO_pa_clearable_loc type. Add __ldcw, and __ldcw_align

1815
1816
1817 Started sometime after version 0.4 release.  Currently the format is
1818 informal.  Eventually should become more GNU-like.
