This instruction causes a transition from x87 FPU to MMX technology operation (that is, the x87 FPU top-of-stack pointer is set to 0 and the x87 FPU tag word is set to all 0s [valid])

It might be useful to include X87STATUS and X87TAG to the operand list of these instructions (CVTPD2PI, CVTPI2PD, CVTPI2PS, CVTPS2PI, MOVDQ2Q, ...).
