[PATCH] D110057: [LoopFlatten] Move it to a LoopPassManager

[Sjoerd Meijer via Phabricator via llvm-commits]

SjoerdMeijer added a comment.

Also having talked to @dmgreen , I am now more convinced that having LoopFlatten separate makes sense (because it doesn't preserve much info as it works on pairs of outer/inner loops and removes the inner if it can). So I think we can abandon this patch. I can look into preserving LCSSA though, perhaps that can be kept up to date avoiding rerunning the pass.
