[PATCH] D32451: Improve profile-guided heuristics to use estimated trip count.

[Michael Kuperstein via Phabricator via llvm-commits]

mkuper added a comment.

When I tried to play with this kind of thing, I got rather inconsistent performance results, because of things like a cold loop within a relatively hot loop.
Do you have any performance numbers for this?
