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::emi...

Thank You. Still getting errors.I have modified my instructions as you said as follows: def GATHER_256B : I<0x68, MRMSrcMem, (outs VR_2048:$dst, VK64WM:$mask_wb), (ins VR_2048:$src1, VK64WM:$mask, i2048mem:$src2), "GATHER_256B\t{$src2, {$dst} {${mask}}|${dst} {${mask}}, $src2}", [(set VR_2048:$dst, VK64WM:$mask_wb, (v64i32 (masked_gather (VR_2048:$src1), VK64WM:$mask, addr:$src2)))],...

Hello, I did as you said, Please tell me whether the following correct now?? def GATHER_256B : I<0x68, MRMSrcMem, (outs VR_2048:$dst, _.KRCWM:$mask_wb), (VR_2048:$src1, _.KRCWM:$mask, ins i2048mem:$src2), "GATHER_256B\t{$src2, {$dst}{${mask}}|${dst} {${mask}}, $src2}"), [(set VR_2048:$dst, _.KRCWM:$mask_wb, (v64i32 (GatherNode (VR_2048:$src1), _.KRCWM:$mask, VR_2048:$src2))],...

i want to implement gather for v64i32. i wrote following code. def GATHER_256B : I<0x68, MRMSrcMem, (outs VR_2048:$dst), (ins i2048mem:$src), "GATHER_256B\t{$src, $dst|$dst, $src}", [(set VR_2048:$dst, (v64i32 (masked_gather addr:$src)))], IIC_MOV_MEM>, TA; def: Pat<(v64f32 (masked_gather addr:$src)), (GATHER_256B
