hi, I had an implementation of loop-rotation that peels the loop such that each conditional is executed at least once. https://reviews.llvm.org/D22630 This helps with LICM when instructions inside a conditional is loop invariant.

I want to read the patch but it's kind of big and unfortunately right now I so don't have time. I'll try to take a look when there is some time. In the meantime, you may want to add Kit Barton and Michael Kruse as reviewers. One q...

Hi, I have read an email from the mail list. And I have a question about loop rotation. What is it if it is the case below. -------------------------------------------------------------------------- loop: A br X B br Y C br loop, Z ------------------------------------------------- Thanks!
