This helps us avoid silly copies when rematting values that are copied to a physical register: leaq _.str44(%rip), %rcx movq %rcx, %rsi call _strcmp becomes: leaq _.str44(%rip), %rsi call _strcmp The coalescer will not touch the movq because that would tie down the physical register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90163 91177308-0d34-0410-b5e6-96231b3b80d8
