[PATCH] D48725: [SLP] Vectorize bit-parallel operations with SWAR.

[Alexey Bataev via Phabricator via llvm-commits]

ABataev added a comment.

1. Do all targets support this kind of transformation? Are they aware of transformation of operations with small vectors into operations on GPR?
2. You need to update the cost model for this kind of transformation.
3. I think this should not the part of SLPVectorizer, looks like it is part of InstCombiner.
