2005-03-21 Hans Boehm 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 probablity, and only on a multiprocessor). 2005-03 Hans Boehm 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 Added libatomic_ops_gpl library with support for mostly lock-free stack and malloc(). 2005-01 Ian Wienand , Al Stone , Hans Boehm Use autoconf, automake, starting with code from Debian package. Don't use libtool. 2005-01 Hans Boehm * 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 * ao_t_is_int.h: Add to trivially support int-wide operations on platforms with int-sized pointers. 2004-12 Hans Boehm * gcc/powerpc.h: First serious attempt to support PowerPC (with help from Maged Michael and others). 2004-12 Hans Boehm * sunc/sparc.[hS]: Added minimal supprt for the Sun SPARC compiler. * atomic_ops_sysdeps.S: Add support for platforms that require out-of-line assmebly code. 2004-10 Hans Boehm 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 Start to add atomic_ops primitives for different sized data. 2003-12-18 Hans Boehm * 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 * 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 * 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 * 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.
