[PATCH] D59710: [SLP] remove lower limit for forming reduction patterns

[Alexey Bataev via Phabricator via llvm-commits]

ABataev added a comment.

It really requires some additional improvvements, because I see a lot of regressions for the cmp instructions. I think, at first you should try to vectorize cmp instructions using the horizontal reductions anf only if it was unsuccessful, you need to try to vectorize the operands of the instruction itself.
