[PATCH] D92701: [SLPVectorize] Call isLegalMaskedGather before creating a gather TreeEntry

[Anton Afanasyev via Phabricator via llvm-commits]

anton-afanasyev added a comment.

I'm agree with @fhahn -- tuning cost model is more right way. Also it could be the case of arch where gathers are missing but it's beneficial to use them for vectorization tree building. They are lowered to scalarized instrs further.
