gcc translates PMULUDQ with an erroneous OPCODE   according to the "AMD64 Architecture Programmer's Manual", on AMD64 architecture (but i think on Intel64 too) the OPCODEs for this instruction should be:  0F F4 /r      when operands are mmx registers or 64-bit memory locations 66 0F F4 /r   when operands are xmm registers or 128-bit memory locations
