 239
 240 2013-03-29  Ivan Maidanski <ivmai@mail.ru>

 245         AO_compare_and_swap_full): Use "+m" asm constraint for *addr instead
 246         of "=m" (because the value pointed by addr is read and written by the
 247         code).
 248
 249 2013-03-13  Ivan Maidanski <ivmai@mail.ru>

 261 2013-02-14  Ivan Maidanski <ivmai@mail.ru>
 262
 263         * src/atomic_ops/sysdeps/gcc/arm.h: Do not include read_ordered.h
 264         (because load_acquire should contain a DMB instruction in a multi-core
 265         case, new load_acquire/read primitives implementation is generalized
 266         using nop_full/read which either contain a DMB instruction, or is just
 267         a compiler barrier for uniprocessor).
 268         * src/atomic_ops/sysdeps/armcc/arm_v6.h: Likewise.

 286         AO_int_fetch_and_add1_acquire, AO_int_fetch_and_add1_release,
 287         AO_int_fetch_and_sub1_acquire, AO_int_fetch_and_sub1_release): Cast
 288         result to unsigned int instead of signed int.

 290 2013-01-13  Ivan Maidanski <ivmai@mail.ru>
 291
 292         * src/atomic_ops/sysdeps/gcc/s390.h: Move include of
 293         ordered_except_wr.h down to be after all_aligned_atomic_load_store.h
 294         inclusion (since the latter defines AO_X_load/store primitives used by
 295         the former header).
 296
 297 2013-01-13  Ivan Maidanski <ivmai@mail.ru>
 298
 299         * src/atomic_ops/sysdeps/msftc/arm.h: Fix a typo in comment (about
 300         SWP).
 301
 302 2013-01-07  Ivan Maidanski <ivmai@mail.ru>
 303
 304         * src/atomic_ops/sysdeps/read_ordered.h (AO_char_load_read,
 305         AO_short_load_read, AO_int_load_read): Change return type (and the
 306         type of "result" local variable) from AO_t to the type matching the
 307         name of the function (i.e., unsigned char/short/int, respectively).
 308
 309 2013-01-06  Ivan Maidanski <ivmai@mail.ru>
 310
 311         * src/atomic_ops/sysdeps/armcc/arm_v6.h (AO_nop_full): Insert

 322
 323         * src/atomic_ops/Makefile.am (BUILT_SOURCES): Define to force
 324         regeneration of generalize-small.h (if the corresponding
 325         source template is changed) before compilation of .c files (that use
 326         atomic_ops.h).
 327
 328 2013-01-02  Ivan Maidanski <ivmai@mail.ru>
 329
 330         * src/atomic_ops/generalize-small.template (AO_XSIZE_fetch_and_add):

 347         variable from long to int to match printf format specifier (when
 348         VERBOSE defined); cast from "arg" pointer to integer via size_t (to
 349         avoid 64-bit compiler warning).
 350
 351 2012-10-08  Ivan Maidanski <ivmai@mail.ru>
 352
 353         * src/atomic_ops/sysdeps/gcc/x86.h (AO_double_compare_and_swap_full):

1907         More work on char, short, int sized data.  Add both
1908         compare_double_and_swap_double and compare_and_swap_double.
1909         Typically each platform will provide at most one of these.
