        global/static variables to have proper (double-word) alignment).

2017-01-26  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops.h (AO_TS_INITIALIZER): Change type from AO_t to

        * tests/test_atomic_include.h: Regenerate.

2017-01-16  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/sysdeps/msftc/arm.h: Remove FIXME about memory barrier
        of _InterlockedOps (they have the correct one according to the MSDN).

2012-10-08  Ivan Maidanski <ivmai@mail.ru>

        * src/Makefile.msft (libatomic_ops_gpl.lib): Do not pass
        "/MACHINE:i386" option to "lib" tool (to select the proper target
        architecture automatically).

2011-08-09  Ivan Maidanski <ivmai@mail.ru>

        * src/Makefile.msft: Replace -o option with /Fo.

        * tests/test_atomic.template (test_atomicXX): Replace assert()
        calls with TA_assert().

        * src/atomic_ops_malloc.c (AO_SIZE_MAX): New macro.
        * src/atomic_ops_malloc.c (SIZET_SAT_ADD): New macro.
        * src/atomic_ops_malloc.c (AO_malloc_large): Use SIZET_SAT_ADD to
        avoid integer overflow when computing the memory size to map (i.e.,
        malloc should handle arguments close to SIZE_MAX correctly).

        * config.sub: Likewise.

2015-01-08  James Cowgill <james410@cowgill.org.uk>

        * src/atomic_ops/sysdeps/gcc/mips.h: Remove inclusion of
        acquire_release_volatile.h (the ISA manuals do not say anything about
        volatile loads / stores having acquire / release semantics).

[7.2f]

2014-05-02  Ivan Maidanski <ivmai@mail.ru>

        * README: Bump version to 7.2f (rev. F).

2013-08-18  Ivan Maidanski <ivmai@mail.ru>

        * aclocal.m4: Regenerate (by autoreconf -vif).

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

        * src/atomic_ops/sysdeps/gcc/arm.h
        (AO_compare_double_and_swap_double): Do not define for
        pre-Clang3.3 (since the latter does not allocate register pairs for
        LDREXD/STREXD instructions properly); add comment.

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

        * src/atomic_ops/sysdeps/gcc/arm.h (AO_compare_double_and_swap_double):
        Swap assembly code operands ("new_val" and "addr") to prevent
        Clang3.3 warning about operand truncation.

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

        * src/atomic_ops/sysdeps/gcc/arm.h
        (AO_compare_double_and_swap_double): Specify that LDREXD and STREXD use
        2 adjacent registers (thus preventing Clang3.3 from register allocation
        failures leading to "registers may not be the same" or
        "even register required" GAS errors).

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

        * src/atomic_ops/generalize.h: Fix a typo in comment
        ("acquire").

2013-04-03  Manuel Serrano <Manuel.Serrano@inria.fr>

        * configure.ac (AM_CONFIG_HEADER): Replace obsolete macro with with
        AC_CONFIG_HEADERS one.

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

        * src/atomic_ops/generalize-small.template (AO_XSIZE_fetch_and_add):
        Do not use AO_EXPECT_FALSE (since defined only in v7.3+).
        * src/atomic_ops/generalize-small.h: Regenerate.

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

        * src/atomic_ops/sysdeps/sunc/x86.h (AO_fetch_and_add_full,
        AO_char_fetch_and_add_full, AO_short_fetch_and_add_full, AO_or_full,
        AO_test_and_set_full,
        AO_compare_and_swap_full): Use "+m" asm constraint for *addr instead
        of "=m" (because the value pointed by addr is read and written by the
        code).

2013-03-13  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/sysdeps/gcc/alpha.h (AO_compare_and_swap): Use "+m"
        asm constraint for *addr instead of "=m" (because the value pointed by
        addr is read and written by the code).

2013-03-12  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/sysdeps/gcc/mips.h (AO_compare_and_swap): Use "+m"
        asm constraint for *addr instead of "+R" (the letter is unsupported
        by clang3.1 resulting in "invalid output constraint in asm" error).

2013-02-14  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/sysdeps/gcc/arm.h: Do not include read_ordered.h
        (because load_acquire should contain a DMB instruction in a multi-core
        case, new load_acquire/read primitives implementation is generalized
        using nop_full/read which either contain a DMB instruction, or is just
        a compiler barrier for uniprocessor).
        * src/atomic_ops/sysdeps/armcc/arm_v6.h: Likewise.
        * src/atomic_ops/sysdeps/msftc/arm.h: Likewise.

2013-01-15  Ivan Maidanski <ivmai@mail.ru>

        * doc/README.txt (_acquire_read): Add information about memory
        barrier (similar as in atomic_ops.h).
        * doc/README.txt (_release_read): Remove information about
        non-existing barrier.

2013-01-14  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/sysdeps/ao_t_is_int.h: Fix a typo in comment.

2013-01-13  Ivan Maidanski <ivmai@mail.ru>

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

2013-01-13  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/sysdeps/gcc/s390.h: Move include of
        ordered_except_wr.h down to be after all_aligned_atomic_load_store.h
        inclusion (since the latter defines AO_X_load/store primitives used by
        the former header).

2013-01-13  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/sysdeps/msftc/arm.h: Fix a typo in comment (about
        SWP).

2013-01-07  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/sysdeps/read_ordered.h (AO_char_load_read,
        AO_short_load_read, AO_int_load_read): Change return type (and the
        type of "result" local variable) from AO_t to the type matching the
        name of the function (i.e., unsigned char/short/int, respectively).

2013-01-06  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/sysdeps/armcc/arm_v6.h (AO_nop_full): Insert
        AO_compiler_barrier for AO_UNIPROCESSOR case.
        * src/atomic_ops/sysdeps/gcc/arm.h (AO_nop_full): Likewise.
        * src/atomic_ops/sysdeps/msftc/arm.h (AO_nop_full): Likewise.
        * src/atomic_ops/sysdeps/msftc/arm.h (AO_nop_full): Refine comment.

2013-01-05  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/Makefile.in: Regenerate (by autoreconf -vif).

2013-01-04  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/Makefile.am (BUILT_SOURCES): Define to force
        regeneration of generalize-small.h (if the corresponding
        source template is changed) before compilation of .c files (that use
        atomic_ops.h).

2013-01-02  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/generalize-small.template (AO_XSIZE_fetch_and_add):
        Add missed definition based on CAS.
        * src/atomic_ops/generalize-small.h: Regenerate.

2013-01-02  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/generalize-small.template (AO_XSIZE_load): Move
        definition (which is based on AO_XSIZE_load_acquire) down to be after
        AO_XSIZE_load_acquire definition.
        * src/atomic_ops/generalize-small.template (AO_XSIZE_store): Move
        definition (which is based on AO_XSIZE_store_release) down to be after
        AO_XSIZE_store_release definition.
        * src/atomic_ops/generalize-small.h : Regenerate.

2012-10-09  Ivan Maidanski <ivmai@mail.ru>

        * tests/test_stack.c (run_one_test): Change type of "index" local
        variable from long to int to match printf format specifier (when
        VERBOSE defined); cast from "arg" pointer to integer via size_t (to
        avoid 64-bit compiler warning).

2012-10-08  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/sysdeps/gcc/x86.h (AO_double_compare_and_swap_full):
        New function (only if __x86_64__) implemented using GCC built-in
        __sync CAS primitive available for x32.
        * src/atomic_ops/sysdeps/gcc/x86.h
        (AO_HAVE_double_compare_and_swap_full): New macro (for x32 only).
        * src/atomic_ops/sysdeps/gcc/x86.h
        (AO_compare_double_and_swap_double_full): Implement using
        double_compare_and_swap_full instead of cmpxchg8b for x32 (since
        x86_64 has cmpxchg and cmpxchg16b but not cmpxchg8b).

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

        * src/atomic_ops.h: Fix typos in comments (update generalize.h
        filename).

2012-10-03  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops.c (AO_pause): Fix millis value (passed to Win32
        Sleep) for the case of 'n' argument in range between 12 and 21,
        inclusive if AO_USE_WIN32_PTHREADS (sleep for 1 ms in this case).
        * src/atomic_ops_stack.c (AO_pause): Evaluate 'msecs' value using the
        same algorithm as in atomic_ops.c (Win32 only).

2012-10-03  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops_stack.c (dummy): Define as static (to make symbol
        without AO_ prefix visible only within this file); initialize to 1
        (same as in atomic_ops.c, so that AO_spin would never really alter
        its value).

2012-10-02  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops.h: Fix 'load' primitive name in comment (replace
        AO_load_release_read with AO_load_acquire_read).

2012-10-02  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/sysdeps/emul_cas.h
        (AO_compare_double_and_swap_double_full): Test (define if)
        AO_HAVE_compare_double_and_swap_double_full macro instead of
        AO_HAVE_compare_double_and_swap_double.

2012-10-01  Ivan Maidanski <ivmai@mail.ru>

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

2012-09-19  Ivan Maidanski <ivmai@mail.ru>

        * configure: Regenerate (by autoreconf -vif using autoconf-2.68,

2012-09-18  Ivan Maidanski <ivmai@mail.ru>

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

2012-09-18  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/sysdeps/sunc/x86_64.h
        (AO_compare_double_and_swap_double_full): Fix inline assembly
        arguments commenting out "m"(*addr) one (similar to that in
        sunc/x86.h) if AO_CMPXCHG16B_AVAILABLE defined.

2012-09-18  Ivan Maidanski <ivmai@mail.ru>

2012-09-05  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/sysdeps/gcc/x86.h
        (AO_compare_double_and_swap_double_full): Re-implement for PIC mode
        saving EBX to a local variable (instead of pushing it to stack) and
        saving memory operand address to a register (edi which is manually
        preserved), so that the whole code could also work even if EBX points
        to memory operand (e.g., in Clang); test __PIC__ using ifdef (instead
        of "if"); update comments; reformat code.

[7.2d]

2012-08-09  Ivan Maidanski <ivmai@mail.ru>

        * src/atomic_ops/sysdeps/gcc/x86.h
        (AO_compare_double_and_swap_double_full): Use EDI register for
        "new_val1" argument in PIC mode only for GCC 4.3+ to workaround
        a problem with older compiler versions (e.g., GCC 4.2.1 [FreeBSD])
        that do not recognize 'D' as a valid register specification; update
        comment.

2012-07-01  Ivan Maidanski <ivmai@mail.ru>

[1.0 release]

2005-03-21  Hans Boehm <Hans.Boehm@hp.com>
        Fix various acquire_release_volatile.h files to reflect the fact
        that both icc and gcc seem to reorder ordinary memory accesses around
        volatile accesses early in the compilation. Modify the acquire
        release test to catch this problem (with high probability, and only on
        a multiprocessor).

2005-03 Hans Boehm <Hans.Boehm@hp.com>
        Fixes for recently introduced bugs.  Update x86 and x86-64 assembly
        syntax to deal with complaints by some recent gcc versions.

2005-02 Hans Boehm <Hans.Boehm@hp.com>
        Added libatomic_ops_gpl library with support for mostly
        lock-free stack and malloc().

        Hans Boehm <Hans.Boehm@hp.com>
        Use autoconf, automake, starting with code from Debian package.
        Don't use libtool.

2005-01 Hans Boehm <Hans.Boehm@hp.com>
        * test_and_set_t_is_ao_t.h, test_and_set_t_is_char.h, others:
        Change most platforms to use byte-wide test-and-set locations.

2005-01 Hans Boehm <Hans.Boehm@hp.com>
        * ao_t_is_int.h: Add to trivially support int-wide operations
        on platforms with int-sized pointers.

2004-12 Hans Boehm <Hans.Boehm@hp.com>
        * gcc/powerpc.h: First serious attempt to support PowerPC (with
        help from Maged Michael and others).

        out-of-line assembly code.

2004-10 Hans Boehm <Hans.Boehm@hp.com>
        More work on char, short, int sized data.  Add both
        compare_double_and_swap_double and compare_and_swap_double.
        Typically each platform will provide at most one of these.

2004-07-02  Ranko Zivojnovic
        Replace both instances of AO_HAVE_NOP_FULL with AO_HAVE_nop_full.

2004-06 Hans Boehm <Hans.Boehm@hp.com>

        * atomic_ops/sysdeps/acquire_release_volatile.h, atomic_ops.h:
        Fix support for ecc on IA64.  Remove compiler_barrier workaround
        for gcc 3.4 and later.

2003-12-17  Hans Boehm  <Hans.Boehm@hp.com>

        * atomic_ops/sysdeps/hpc/{ia64.h,hppa.h},
        atomic_ops/sysdeps/msftc/x86.h, Makefile, Makefile.atomic_ops,
        Makefile.atomic_ops.msft, atomic_ops.h: Add initial support
        for atomic_ops for VC++/Windows/X86 and HP/UX with the HP
        compiler on PA_RISC and IA64.

2003-12-09  Hans Boehm  <Hans.Boehm@hp.com>

        * many: Install under "atomic_ops" instead of "ao".
        Change atomic_ops include file structure.  Auxiliary include
        files are all under include/atomic_ops.
        Fix (hopefully) "make dist" in atomic_ops distribution.
        Renamed various types to end in _t, though the old versions
        are still defined for backward compatibility.

2003-12-08  Carlos O'Donell  <carlos@baldric.uwo.ca>

        * ao_sysdeps/gcc/hppa.h: Define AO_CLEAR macro. Change
        AO_pa_clearable_loc type. Add __ldcw, and __ldcw_align
        helper macros. AO_test_and_set_full uses helper macros.


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