Dmitry Vyukov 1e4b54d196 asan: rename the file (it's not 64-bit specific anymore) 
llvm-svn: 172518
 2013-01-15 08:04:27 +00:00
Will Dietz 9d3209b5c7 [ubsan] Use __sanitizer::atomic_exchange(), prefer shared impl. 
Specify weaker memory order in case we optimize for it in the future,
presently still doing same __sync_lock_test_and_set() as before.

Change suggested by Alexey Samsonov, thanks!

Evgeniy Stepanov 99d91289b6 Move large part of asan_test_utils.h to sanitizer_common. 
Move my_rand() to the common header.

This lets us avoid the use of rand_r in sanitizer_common tests.
There is no rand_r on Android.

Kostya Serebryany b05fc3a493 [asan] use the slow CFI-based unwinder when reporting an error. Still use the fast unwinder for malloc/free. Linux-x86-only for now.
