[PATCH] D128011: [SimplifyLibCalls] Transform memchr(STR, C, N) to chain of ORs

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

Why does this need a phase ordering test? What is the output after just InstCombine for it? Does InstCombine not reliably reduce the comparisons and require SimplifyCFG switch optimization? What if there is no actual branch involved and SimplifyCFG doesn't reduce it?
