Bug: 3381237

d55f0adfb5ec4202ad5bd5d188e66c0f6a27b0aa 28-Sep-2010 Carl Shapiro <cshapiro@google.com> Qualify the source argument of atomic loads as a const pointer.

Also normalizes the opening brace placment in a few locations.

93b0cb40c18cae594c931677be2b9214420610b7 04-Jun-2010 Carl Shapiro <cshapiro@google.com> Define inline atomic operations for x86 and ARM.

This change moves the ARM definitions into GCC extended inline
assembler. In addition, the same set of x86 definitions are now
shared among all x86 targets.

8dfa47da8cb33ebaf7aae6db6548e75ed86e8f1e 27-May-2010 Andy McFadden <fadden@android.com> Atomic/SMP update, part 2.

Added new atomic functions, renamed some old ones. Some #defines have
been added for backward compatibility.

Merged the pre- and post-ARMv6 implementations into a single file.

Renamed the semi-private __android_membar_full_smp to USE_SCREAMING_CAPS
since that's more appropriate for a macro.

Added lots of comments.

Note Mac OS X primitives have not been tested.

ac322da69ee48aa792baf5c48cfb719ce077f67e 20-May-2010 Andy McFadden <fadden@android.com> Atomic/SMP update.

Added atomic-inline.h. Added a platform-specific memory barrier call
there.

Added android_atomic_acquire_cmpxchg() and android_atomic_release_store().
Not tested on Mac OS X or SH.

Added memory barrier calls to linux-x86 atomics. Mac OS X has barrier
functions already. sh isn't really SMP-ready. linux-arm needs work
(to be done in a separate change).

Updated the makefile to make the SMP state visible to the code here.
Note that host binaries are NOT built with SMP enabled; while our hosts
are very likely SMP, it's not worth figuring out e.g. whether it's okay
to use the SSE2 mfence instruction or have to use something else. We
haven't had barriers enabled in host tools before, so there's probably
no need to stat now.

Removed quasiatomic 64-bit calls (now part of Dalvik).
