For example vpsrld xmm0, xmm1, xmm2 was assembled to vpslld xmm0, xmm1, xmm2

 00000000  C5 F1 F2/ C2                 vpsrld  xmm0, xmm1, xmm2
 00000004  C5 F1 F2/ C2                 vpslld  xmm0, xmm1, xmm2

This is a part of listing file. Output for these 2 lines are exact same.

vpsrlw xmm, xmm, xmm and vpsrlq xmm, xmm, xmm are Ok.
vpsrld xmm, xmm, imm8 is also Ok.

Thank you for contacting Microsoft and for using the Microsoft Macro Assembler.

Good catch. This is an incomplete cut-n-paste edit on our side. The VPSRLD xmm, xmm, xmm intruction should be emitting a 0xD2 opcode instead of a 0xF2.

btw, we very much appreciate this feedback.
