[PATCH] D20639: SLPVectorizer: Move propagateMetadata to VectorUtils

[Michael Zolotukhin via llvm-commits]

mzolotukhin added a comment.

As far as I remember, the version in LoopVectorizer propagates metadata from a single instruction, not from a vector of instructions. However, I think it should be just considered as a special case - i.e. we are still propagating metadata from a vector of instructions, but they all are the same. So, if it doesn't complicate the code much, could you please try refactoring it from there too?

Thanks,
Michael
