For certain occurrences of nandx/norx, we declare a ReadWrite constraint on the destination register, even though the value of the destination register is irrelevant. This false dependency would force the RegCache to generate a redundant MOV when the destination register wasn't already assigned to a host register. Example 1: BF 00 00 00 00 mov edi,0 8B FE mov edi,esi F7 D7 not edi Example 2: 8B 7D 80 mov edi,dword ptr [rbp-80h] 8B FE mov edi,esi F7 D7 not edi |
