A new opcode map about AVX-512, which introduces ZMM registers which has 512-bit width. Perhaps, we need to introduce new code of operand type for that new large registers, I guess it is Octa-Quadword(oq)? :) And also, MASK instructions may require new addressing method codes for opmask registers. Of course I can make new one for those and update after official opcode map is released, as I did on AVX instructions. Thank you, -- Masami HIRAMATSU IT Management Research Dept.
