do the atomic operation under the sync object mutex
make acquire/release sync atomic with the operation itself
combine acquire and release into a single acq_rel operation

this allows to build tsan runtime as dynamic library

[asan] fix Android build by not calling GetPageSizeCached in a test (no need for the page size anyway)

[asan/tsan] get rid of kPageSize completely in favor of GetPageSizeCached(). This makes the code friendly to more platforms

llvm-svn: 168537

llvm-svn: 168518

[asan] get rid of some of the uses of kPageSize. The intent is to get rid of it completely to support platforms with multiple possible page sizes.

[asan/tsan] do not use __WORDSIZE macro, as it is glibc-private thing. Instead, define our own SANITIZER_WORDSIZE

[Sanitizer] replace while with internal_memset to make sure compiler won't replace it with library memset

llvm-svn: 168422

(do not execute synchronous signals in recursive interceptors)

[asan] pop the two internal functions from the stack trace produced by _Unwind_Backtrace (Peter Bergner)
