[PATCH] D132458: [LoopVectorize] Synthesize mask operands for vector variants as needed

[Graham Hunter via Phabricator via llvm-commits]

huntergr updated this revision to Diff 477717.
huntergr retitled this revision from "[LoopVectorize] Support masked function vectorization" to "[LoopVectorize] Synthesize mask operands for vector variants as needed".

huntergr added a comment.

Updated to store the pointer to the vector function in the recipe rather than looking it up again during recipe execution. Forced generation of a plan per VF when there are variants available for those VFs. Added some new tests for masked vs. unmasked variants.

I'm not fond of adding the optional parameters LoopVectorizationCostModel::getVectorCallCost -- it feels like function lookup needs to be split out of it, but I'd like to get some feedback from others before doing so.
