> Missing PREFIX_OPCODE?

Legacy both have PREFIX_OPCODE, but currently EVEX seems to only use the vex.w bit to check the operand size. I'm confused whether we should add PREFIX_OPCODE ? Currently it reports bad.
case PREFIX_OPCODE: 
...
         (ins.vex.evex && dp->prefix_requirement != PREFIX_DATA
              && !ins.vex.w != !(ins.used_prefixes & PREFIX_DATA))
...


Thanks,
Lili.
