[PATCH] D128164: [LoopPeel] Forget SCEV for updated exit phi values.

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

This looks reasonable to me -- only thing that's not entirely clear to me is why forgetTopmostLoop() doesn't end up doing this. The forgetLoop() implementation is very aggressive, and I would have expected that the use-def walk would reach the exit phis as well.
