2016-04-28[test/asan] Update a test case to work with old Darwin SDK'sVedant Kumar
On Darwin, MAP_ANONYMOUS is a synonym for MAP_ANON. However, some SDK's don't define MAP_ANONYMOUS. Use MAP_ANON to work around this. (As a point of interest, the situation is exactly reversed on Linux.) git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@267907 91177308-0d34-0410-b5e6-96231b3b80d8

This fixes fails in test/msan/dlerror.cc - when real dlerror calls strcmp, our strcmp interceptor now skips poison checking, since it's called in interceptor context. Strictly speaking, only the dlerror change is necessary to fix the fail, but let's also change the other two just in case.

2016-04-14[tsan] Fix size reporting for OS X zone allocator with 0-sized allocationsKuba Brecka
The custom zone implementation for OS X must not return 0 (even for 0-sized allocations). Returning 0 indicates that the pointer doesn't belong to the zone. This can break existing applications. The underlaying allocator allocates 1 byte for 0-sized allocations anyway, so returning 1 in this case is okay.

2016-04-07[sanitizer] Fix sem_init_glibc.cc test on __HAVE_64B_ATOMIC arches.Evgeniy Stepanov
glibc can use one of 2 layouts for semaphores: architectures that don't HAVE_64B_ATOMIC use an uint32_t field with semaphore value, then a private field, then a waiting thread count field - this is the layout currently assumed by the test. However, HAVE_64B_ATOMIC arches use a fused uint64_t field that contains the value in low bits and waiting thread count in high bits, followed by a private field. This resulted in taking private field from the wrong offset on 64-bit atomic platforms (the test still passed, but didn't actually test the private field). On big-endian platforms, this resulted in a fail, since the first 4 bytes overlay the thread count field, and not the value field. Found while porting ASan to s390x.

2016-04-07[tsan] Remove long sleeps from fork testsKuba Brecka
On one of our testing machines, we're running the tests under heavy load, and especially in the fork-based TSan tests, we're seeing timeouts when a test uses sleep(10), assuming that calling fork() on another thread will finish sooner than that.
