Hi,
when compiling with -fsanitize=address we define __SANITIZE_ADDRESS__
macros, but we don't do this for -fsanitize=thread and -fsanitize=undefined.
Perhaps we should be more symmetric here and define corresponding
__SANITIZE_THREAD__ and __SANITIZE_UNDEFINED__ macros respectively?
Are these available in Clang as well?
AFAIK Clang has __has_feature(address_sanitizer) and
__has_feature(thread_sanitizer). UBSan doesn't have such things.
I added two simple test cases to c-c++-common/{ub, t}san/ directories that
just verify if __SANITIZE_THREAD__ (__SANITIZE_UNDEFINED__) is defined. Is
that a proper way how we check that the macros defined correctly? Does this
patch looks reasonable?
