I need to implement an instruction which has 2 read-write registers, so I added let Constraints = "$src1 = $dst, $mask = $mask_wb" in { ... def rm : AVX28I<opc, MRMSrcMem, (outs VR128:$dst, VR128:$mask_wb), (ins VR128:$src1, v128mem:$src2, VR128:$mask), ... } There is a problem since MRMSrcMem assumes the 2nd physical operand is a memory operand. See the section about MRMSrcMem in RecognizableInstr::emitInstructionSpecifier. And the abo...
