[PATCH] D42365: [LoopFlatten] Add a loop-flattening pass

[Sjoerd Meijer via Phabricator via llvm-commits]

SjoerdMeijer updated this revision to Diff 295285.
SjoerdMeijer added a comment.

I've added the test cases from PR40581. Test v0 does not trigger yet, test v1 triggers. I propose adding support for v0 once we've got something in-tree.
