Evan Cheng b9ab88ccd5 Local spiller optimization: ... Turn this: movswl %ax, %eax movl %eax, -36(%ebp) xorl %edi, -36(%ebp) into movswl %ax, %eax xorl %edi, %eax movl %eax, -36(%ebp) by unfolding the load / store xorl into an xorl and a store when we know the value in the spill slot is available in a register. This doesn't change the number of instructions but reduce the number of times memory is accessed. Also unfold some load folding instructions and reuse the value when similar situation presents itself. llvm-svn: 42947		2007-10-13 02:50:24 +00:00
