XDIS b8: XOP       XOP        8FEA7012CA03000000       lwpval ecx, edx, 0x3
ERROR: GENERAL_ERROR Could not decode at offset: 0xc1 PC: 0xc1: [8FEAF012CA03000000]

In XED data file:

PATTERN: XOPV 0x12 VNP W0 VL128  XMAPA MOD[0b11] MOD=3 REG[0b001] RM[nnn] UIMM32()
OPERANDS: REG0=VGPRy_N():w:y REG1=GPRv_B():r:d IMM0:r:d

same as

LWPVAL reg32.vvvv, reg/mem32, imm32 8F RXB.0A 0.src1.0.00 12 /1 /imm32
LWPVAL reg64.vvvv, reg/mem32, imm32 8F RXB.0A 1.src1.0.00 12 /1 /imm32

Seems to be an error action?

Thanks for reporting this. Confirmed. I think I just need to remove the "W0" from LWPVAL/LWPINS.
