In the case of SSE/SSE2/SSE3/SSSE3 SIMD instructions: the 66H, F2H, and F3H prefixes are mandatory for opcode extensions. In such a case, there is no interaction between a valid REX.W prefix and the home of the 66H instruction prefix and the REX.W field is properly set, the prefix specifies an operand size is 32 bits.
