[PATCH] D76210: [Attributor] AAReachability : use isPotentiallyReachable in isKnownReachable

[Johannes Doerfert via Phabricator via llvm-commits]

jdoerfert added a comment.

There are two issues with a `isPotentiallyReachable` approach, not to say we cannot make it work. What we need is 1) use liveness information  from AAIsDead 2) caching of the results. We can do that in follow up patches though.
