Dan Gohman 584fedf188 Teach two-address lowering how to unfold a load to open up commuting ... opportunities. For example, this lets it emit this: movq (%rax), %rcx addq %rdx, %rcx instead of this: movq %rdx, %rcx addq (%rax), %rcx in the case where %rdx has subsequent uses. It's the same number of instructions, and usually the same encoding size on x86, but it appears faster, and in general, it may allow better scheduling for the load. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106493 91177308-0d34-0410-b5e6-96231b3b80d8		2010-06-21 22:17:20 +00:00
