Kostya Serebryany 125e26d49b [tsan] add write_range/read_range hooks to common interceptors called from tsan (to find races on read/pread/etc) 
llvm-svn: 172714
 2013-01-17 13:18:40 +00:00
Kostya Serebryany 93ebdb5d64 [sanitizer] a bit more unification for interceptors (merge read/pread/pread64 in asan and tsan)

Kostya Serebryany b7062cec53 [asan] asan_allocator2: fix the memalign handling (clear the first word of allocated chunk in case there is an old memalign magic) 
llvm-svn: 172603
 2013-01-16 09:12:14 +00:00
Kostya Serebryany d8b1f78296 [asan] enable asan_allocator2 by default on Linux. Will enable it on other platforms and remove the old one later, after additional testing. The new allocator is much faster and uses less memory

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.
