[PATCH] D32871: [LV] Using VPlan to model the vectorized code and drive its transformation

[Ayal Zaks via Phabricator via llvm-commits]

Ayal updated this revision to Diff 112467.
Ayal added a comment.

Fix PR34248: pack a predicated scalar into a vector only when vectorizing; avoid doing so when only unrolling. Add a test derived from the reproducer of PR34248.
