[PATCH] D50940: [sanitizer] Change Mmap*NoAccess to return MMAP_FAILED (~(uptr)0) on error

[Kostya Kortchinsky via Phabricator via llvm-commits]

cryptoad added a comment.

Other wrong use:
__hwasan::MapDynamicShadow: checks for failure with ~(uptr)0 (while it's the syscall return value)
__asan::FindDynamicShadowStart: same as above
__asan::PremapShadow: same as above
