Hal Finkel	786d7d887a	[PowerPC] Use a small cleanup pass to remove VSX self copies ... As explained in r204976, because of how the allocation of VSX registers interacts with the call-lowering code, we sometimes end up generating self VSX copies. Specifically, things like this: %VSL2<def> = COPY %F2, %VSL2<imp-use,kill> (where %F2 is really a sub-register of %VSL2, and so this copy is a nop) This adds a small cleanup pass to remove these prior to post-RA scheduling. llvm-svn: 204980	2014-03-27 23:12:31 +00:00
