[PATCH] D86844: [LoopDeletion] Allows deletion of possibly infinite side-effect free loops

[Atmn Patel via Phabricator via cfe-commits]

atmnpatel updated this revision to Diff 308249.
atmnpatel added a comment.

I believe this happened becase when I removed the loop, I did not update MemorySSA. The exact error was from GVN, but this update seems to fix the stage 2 build compile time error locally (I checked by running the build bot script).
