[PATCH] D55263: [CodeGen][ExpandMemcmp] Add an option for allowing overlapping loads.

[John Reagan via Phabricator via llvm-commits]

JohnReagan added a comment.

One of my coworkers did an informal test last year and saw that newer Intel CPUs optimization of REP-string-op-instruction was faster than using SSE2 (he used large data sizes, not anything in the shorter ranges this patch deals with).  Is that something that should be looked at?  (or has somebody done that examination already)
