New issue 532 by [email protected]: [PATCH] Add the atomicops
implementation for compiler-based ThreadSanitizer
http://code.google.com/p/protobuf/issues/detail?id=532
The attached patch adds a special implementation for atomic operations for
ThreadSanitizer, a compiler-based data race detector
(clang.llvm.org/docs/ThreadSanitizer.html)
This implementation is included in the case the THREAD_SANITIZER macro is
defined. It uses the ThreadSanitizer API functions that describe the
semantics of the atomics to the tool.
Similar atomics implementations are used by Chromium
(http://src.chromium.org/viewvc/chrome/trunk/src/base/atomicops_internals_tsan.h?revision=172032)
and V8.
