Chandler Carruth 353476d536 Teach the new SROA a new trick. Now we zap any memcpy or memmoves which ... are in fact identity operations. We detect these and kill their partitions so that even splitting is unaffected by them. This is particularly important because Clang relies on emitting identity memcpy operations for struct copies, and these fold away to constants very often after inlining. Fixes the last big performance FIXME I have on my plate. llvm-svn: 165285		2012-10-05 01:29:09 +00:00
