[PATCH] D142015: [LV] Plan with and without FoldTailByMasking

[Thorsten via Phabricator via llvm-commits]

tschuett added a comment.

Cloud you model this approach instead as a VPlan transformation, instead of hardcoding unscalable flags. Transform: add tail folding. Transform: add masked tail folding. Transform: add scalar tail. Then you can take **the** cost model to decide which is more desirable.
