  83
  84         * src/atomic_ops/sysdeps/gcc/arm.h
  85         (AO_compare_double_and_swap_double): Do not define for

  88
  89 2013-08-17  Ivan Maidanski <ivmai@mail.ru>

  98         (AO_compare_double_and_swap_double): Specify that LDREXD and STREXD use
  99         2 adjacent registers (thus preventing Clang3.3 from register allocation
 100         failures leading to "registers may not be the same" or
 101         "even register required" GAS errors).

 103 2013-07-30  Ivan Maidanski <ivmai@mail.ru>
 104

 114
 115         * src/atomic_ops/generalize-small.template (AO_XSIZE_fetch_and_add):

 117         * src/atomic_ops/generalize-small.h: Regenerate.
 118
 119 2013-03-29  Ivan Maidanski <ivmai@mail.ru>
 120

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

 151
 152         * doc/README.txt (_acquire_read): Add information about memory
 153         barrier (similar as in atomic_ops.h).
 154         * doc/README.txt (_release_read): Remove information about
 155         non-existing barrier.
 156
 157 2013-01-14  Ivan Maidanski <ivmai@mail.ru>

 162
 163         * src/atomic_ops/sysdeps/ao_t_is_int.h
 164         (AO_int_load_acquire, AO_int_fetch_and_add_full,
 165         AO_int_fetch_and_add1_acquire, AO_int_fetch_and_add1_release,
 166         AO_int_fetch_and_sub1_acquire, AO_int_fetch_and_sub1_release): Cast
 167         result to unsigned int instead of signed int.
 168
 169 2013-01-13  Ivan Maidanski <ivmai@mail.ru>
 170
 171         * src/atomic_ops/sysdeps/gcc/s390.h: Move include of
 172         ordered_except_wr.h down to be after all_aligned_atomic_load_store.h
 173         inclusion (since the latter defines AO_X_load/store primitives used by
 174         the former header).
 175
 176 2013-01-13  Ivan Maidanski <ivmai@mail.ru>
 177
 178         * src/atomic_ops/sysdeps/msftc/arm.h: Fix a typo in comment (about
 179         SWP).
 180
 181 2013-01-07  Ivan Maidanski <ivmai@mail.ru>
 182
 183         * src/atomic_ops/sysdeps/read_ordered.h (AO_char_load_read,
 184         AO_short_load_read, AO_int_load_read): Change return type (and the
 185         type of "result" local variable) from AO_t to the type matching the
 186         name of the function (i.e., unsigned char/short/int, respectively).
 187
 188 2013-01-06  Ivan Maidanski <ivmai@mail.ru>
 189
 190         * src/atomic_ops/sysdeps/armcc/arm_v6.h (AO_nop_full): Insert
 191         AO_compiler_barrier for AO_UNIPROCESSOR case.
 192         * src/atomic_ops/sysdeps/gcc/arm.h (AO_nop_full): Likewise.

 200 2013-01-04  Ivan Maidanski <ivmai@mail.ru>
 201
 202         * src/atomic_ops/Makefile.am (BUILT_SOURCES): Define to force
 203         regeneration of generalize-small.h (if the corresponding
 204         source template is changed) before compilation of .c files (that use
 205         atomic_ops.h).
 206
 207 2013-01-02  Ivan Maidanski <ivmai@mail.ru>
 208
 209         * src/atomic_ops/generalize-small.template (AO_XSIZE_fetch_and_add):
 210         Add missed definition based on CAS.
 211         * src/atomic_ops/generalize-small.h: Regenerate.
 212
 213 2013-01-02  Ivan Maidanski <ivmai@mail.ru>
 214
 215         * src/atomic_ops/generalize-small.template (AO_XSIZE_load): Move
 216         definition (which is based on AO_XSIZE_load_acquire) down to be after
 217         AO_XSIZE_load_acquire definition.
 218         * src/atomic_ops/generalize-small.template (AO_XSIZE_store): Move

 222
 223 2012-10-09  Ivan Maidanski <ivmai@mail.ru>
 224
 225         * tests/test_stack.c (run_one_test): Change type of "index" local
 226         variable from long to int to match printf format specifier (when
 227         VERBOSE defined); cast from "arg" pointer to integer via size_t (to
 228         avoid 64-bit compiler warning).
 229
 230 2012-10-08  Ivan Maidanski <ivmai@mail.ru>
 231
 232         * src/atomic_ops/sysdeps/gcc/x86.h (AO_double_compare_and_swap_full):

 241
 242 2012-10-05  Ivan Maidanski <ivmai@mail.ru>

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

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

 256
 257         * src/atomic_ops_stack.c (dummy): Define as static (to make symbol
 258         without AO_ prefix visible only within this file); initialize to 1
 259         (same as in atomic_ops.c, so that AO_spin would never really alter
 260         its value).
 261
 262 2012-10-02  Ivan Maidanski <ivmai@mail.ru>
 263
 264         * src/atomic_ops.h: Fix 'load' primitive name in comment (replace

 274 2012-10-01  Ivan Maidanski <ivmai@mail.ru>
 275
 276         * src/atomic_ops/sysdeps/standard_ao_double_t.h (double_ptr_storage):

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

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

1785 2004-10 Hans Boehm <Hans.Boehm@hp.com>
1786         More work on char, short, int sized data.  Add both
1787         compare_double_and_swap_double and compare_and_swap_double.
1788         Typically each platform will provide at most one of these.
1789
1790 2004-07-02  Ranko Zivojnovic
1791         Replace both instances of AO_HAVE_NOP_FULL with AO_HAVE_nop_full.

1807         for atomic_ops for VC++/Windows/X86 and HP/UX with the HP
1808         compiler on PA_RISC and IA64.
1809

1822         AO_pa_clearable_loc type. Add __ldcw, and __ldcw_align

1824
1825
1826 Started sometime after version 0.4 release.  Currently the format is
1827 informal.  Eventually should become more GNU-like.
