[PATCH] D102834: [SLPVectorizer] Implement initial memory versioning.

[Sjoerd Meijer via Phabricator via llvm-commits]

SjoerdMeijer added a subscriber: dmgreen.
SjoerdMeijer added a comment.

Relaying a message from @dmgreen about the emitted runtime checks: could they tank performance in some cases? For example, in (nested) loops? Or are they trivially hoisted if they are emitted in a loop nest? Do we have any idea or data about this?
