Bill Wendling 48f7f237ea A problem that's exposed when machine LICM is enabled. Consider this code: ... LBB1_3: # bb ... xorl %ebp, %ebp subl (%ebx), %ebp ... incl %ecx cmpl %edi, %ecx jl LBB1_3 # bb Whe using machine LICM, LLVM converts it into: xorl %esi, %esi LBB1_3: # bb ... movl %esi, %ebp subl (%ebx), %ebp ... incl %ecx cmpl %edi, %ecx jl LBB1_3 # bb Two address conversion inserts the copy instruction. However, it's cheaper to rematerialize it, and remat helps reduce register pressure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51562 91177308-0d34-0410-b5e6-96231b3b80d8		2008-05-26 05:18:34 +00:00
