	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.

	Replace both instances of AO_HAVE_NOP_FULL with AO_HAVE_nop_full.

2004-06 Hans Boehm <Hans.Boehm@hp.com>
	Start to add atomic_ops primitives for different sized data.

2003-12-18  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.
