David Bolvansky ff0ad3c43d [InstCombine] mempcpy(d,s,n) to memcpy(d,s,n) + n ... Summary: Back-end currently expands mempcpy, but middle-end should work with memcpy instead of mempcpy to enable more memcpy-optimization. GCC backend emits mempcpy, so LLVM backend could form it too, if we know mempcpy libcall is better than memcpy + n. https://godbolt.org/z/dOCG96 Reviewers: efriedma, spatel, craig.topper, RKSimon, jdoerfert Reviewed By: efriedma Subscribers: hjl.tools, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D65737 llvm-svn: 370593		2019-08-31 18:19:05 +00:00
