[PATCH] D114171: [SLP]Improve reductions analysis and emission, part 1.

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

It looks like this change has non-trivial compile-time impact in some cases. One large regression by 34% is on `me_distortion.c` from lencod at `O3` (without codegen changes, so this is not due to better vectorization).
