[PATCH] D44565: [SLP] Add a check before skipping inserting a trunc after z|sext vectorization tree root

[Alexey Bataev via Phabricator via llvm-commits]

ABataev added a comment.

Not sure that this should be handled in SLPVectorizer. It is the problem of the instcombiner that it is too optimistic sometimes, not the problem of the SLPVectorizer. InstCombiner should check that this kind of the expansion is good for the current platform
