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

  83
  84 2013-08-17  Ivan Maidanski <ivmai@mail.ru>

  92         * src/atomic_ops/sysdeps/gcc/arm.h
  93         (AO_compare_double_and_swap_double): Specify that LDREXD and STREXD use
  94         2 adjacent registers (thus preventing Clang3.3 from register allocation
  95         failures leading to "registers may not be the same" or
  96         "even register required" GAS errors).
  97
  98 2013-07-30  Ivan Maidanski <ivmai@mail.ru>
  99

 109
 110         * src/atomic_ops/generalize-small.template (AO_XSIZE_fetch_and_add):

 112         * src/atomic_ops/generalize-small.h: Regenerate.
 113
 114 2013-03-29  Ivan Maidanski <ivmai@mail.ru>
 115

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

 145 2013-01-15  Ivan Maidanski <ivmai@mail.ru>
 146
 147         * doc/README.txt (_acquire_read): Add information about memory
 148         barrier (similar as in atomic_ops.h).
 149         * doc/README.txt (_release_read): Remove information about
 150         non-existing barrier.
 151
 152 2013-01-14  Ivan Maidanski <ivmai@mail.ru>

 158         * src/atomic_ops/sysdeps/ao_t_is_int.h
 159         (AO_int_load_acquire, AO_int_fetch_and_add_full,
 160         AO_int_fetch_and_add1_acquire, AO_int_fetch_and_add1_release,
 161         AO_int_fetch_and_sub1_acquire, AO_int_fetch_and_sub1_release): Cast
 162         result to unsigned int instead of signed int.
 163
 164 2013-01-13  Ivan Maidanski <ivmai@mail.ru>
 165
 166         * src/atomic_ops/sysdeps/gcc/s390.h: Move include of
 167         ordered_except_wr.h down to be after all_aligned_atomic_load_store.h
 168         inclusion (since the latter defines AO_X_load/store primitives used by
 169         the former header).
 170
 171 2013-01-13  Ivan Maidanski <ivmai@mail.ru>
 172
 173         * src/atomic_ops/sysdeps/msftc/arm.h: Fix a typo in comment (about
 174         SWP).
 175
 176 2013-01-07  Ivan Maidanski <ivmai@mail.ru>
 177
 178         * src/atomic_ops/sysdeps/read_ordered.h (AO_char_load_read,
 179         AO_short_load_read, AO_int_load_read): Change return type (and the
 180         type of "result" local variable) from AO_t to the type matching the
 181         name of the function (i.e., unsigned char/short/int, respectively).
 182
 183 2013-01-06  Ivan Maidanski <ivmai@mail.ru>
 184
 185         * src/atomic_ops/sysdeps/armcc/arm_v6.h (AO_nop_full): Insert
 186         AO_compiler_barrier for AO_UNIPROCESSOR case.
 187         * src/atomic_ops/sysdeps/gcc/arm.h (AO_nop_full): Likewise.
 188         * src/atomic_ops/sysdeps/msftc/arm.h (AO_nop_full): Likewise.

 196
 197         * src/atomic_ops/Makefile.am (BUILT_SOURCES): Define to force
 198         regeneration of generalize-small.h (if the corresponding
 199         source template is changed) before compilation of .c files (that use
 200         atomic_ops.h).
 201
 202 2013-01-02  Ivan Maidanski <ivmai@mail.ru>
 203
 204         * src/atomic_ops/generalize-small.template (AO_XSIZE_fetch_and_add):

 206         * src/atomic_ops/generalize-small.h: Regenerate.
 207
 208 2013-01-02  Ivan Maidanski <ivmai@mail.ru>
 209
 210         * src/atomic_ops/generalize-small.template (AO_XSIZE_load): Move
 211         definition (which is based on AO_XSIZE_load_acquire) down to be after

 217
 218 2012-10-09  Ivan Maidanski <ivmai@mail.ru>
 219
 220         * tests/test_stack.c (run_one_test): Change type of "index" local
 221         variable from long to int to match printf format specifier (when
 222         VERBOSE defined); cast from "arg" pointer to integer via size_t (to
 223         avoid 64-bit compiler warning).
 224
 225 2012-10-08  Ivan Maidanski <ivmai@mail.ru>
 226
 227         * src/atomic_ops/sysdeps/gcc/x86.h (AO_double_compare_and_swap_full):

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

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

 251
 252         * src/atomic_ops_stack.c (dummy): Define as static (to make symbol
 253         without AO_ prefix visible only within this file); initialize to 1
 254         (same as in atomic_ops.c, so that AO_spin would never really alter
 255         its value).
 256
 257 2012-10-02  Ivan Maidanski <ivmai@mail.ru>
 258
 259         * src/atomic_ops.h: Fix 'load' primitive name in comment (replace

 270
 271         * src/atomic_ops/sysdeps/standard_ao_double_t.h (double_ptr_storage):

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

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

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

1743 2005-03-21  Hans Boehm <Hans.Boehm@hp.com>
1744         Fix various acquire_release_volatile.h files to reflect the fact
1745         that both icc and gcc seem to reorder ordinary memory accesses around
1746         volatile accesses early in the compilation. Modify the acquire

1780 2004-10 Hans Boehm <Hans.Boehm@hp.com>
1781         More work on char, short, int sized data.  Add both
1782         compare_double_and_swap_double and compare_and_swap_double.
1783         Typically each platform will provide at most one of these.
1784
1785 2004-07-02  Ranko Zivojnovic
1786         Replace both instances of AO_HAVE_NOP_FULL with AO_HAVE_nop_full.

1802         for atomic_ops for VC++/Windows/X86 and HP/UX with the HP
1803         compiler on PA_RISC and IA64.
1804

1806
1807         * many: Install under "atomic_ops" instead of "ao".

1817         AO_pa_clearable_loc type. Add __ldcw, and __ldcw_align

1819
1820
1821 Started sometime after version 0.4 release.  Currently the format is
1822 informal.  Eventually should become more GNU-like.
