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

[Atmn Patel via Phabricator via llvm-commits]

atmnpatel updated this revision to Diff 296753.
atmnpatel added a comment.

Updates made to try to remove infinite loops with no exit edge. It seems to work with the new pass manager, but hopelessly breaks for the old pass manager, changes planned.
