[PATCH] D93734: [LoopDeletion] Insert an early exit from dead path in loop

[Jonas Paulsson via Phabricator via llvm-commits]

jonpa updated this revision to Diff 329788.
jonpa added a comment.

Patch updated to also run with the new pass manager.

This now gives a ~9% improvement on Omnetpp - just like it was with the legacy pass manager (before but not after Florians patch, I believe).

@fhahn : are you going to port your improvement to loop unswitching to newpm?
