This revision now requires changes to proceed.

Toolchain vendors aren't currently required to provide default blacklists for every sanitizer clang supports. We don't ship a default ubsan blacklist on macOS, so this patch would break ubsan for all our users.

I think we need to find a different solution here. Have you considered making a blacklist mandatory just for CFI? Alternatively, if the blacklist is tiny and never changes, perhaps we could embed it within the compiler?
