[PATCH] D144319: [SimplifyCFG] Check if the return instruction causes undefined behavior

[DianQK via Phabricator via llvm-commits]

DianQK added a comment.

According to https://github.com/google/sanitizers/wiki/SanitizerBotReproduceBuild, I can reproduce the issue locally. But this build is taking too long, and I'm still verifying the sanitizer checks after the fix.
