[llvm-commits] [PATCH] asan-rt: discover main thread stack limits without pthread

[Evgeniy Stepanov]

Hi,

if __asan_init is called from .preinit_array, pthread_getattr_np may
become unsafe. This patch adds a different way of locating the stack
of the main thread with a combination of getlrimit() and
/proc/self/maps.
