tsanv2: implement __has_feature(thread_sanitizer) #101

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
clang must define THREAD_SANITIZER when -fthread-sanitizer is passed.

We don't define ADDRESS_SANITIZER for ASan, so we should not do this for TSan, 
either.
We use has_feature macros instead.

Yes, clang does not define ADDRESS_SANITIZER -- the clang folks rejected that 
patch and they had reasons. 
but asan can use "__has_feature(address_sanitizer)"
