Comment on x86 architecture 1 byte opcodesparentComments−jeffbee10moTons of these have immediate operands. The question becomes is ADD with an implicit register destination and an immediate value in the next byte a "1-byte opcode"?−Sharlin10moYes, indeed. I'd allow only mov to have a memory or immediate parameter as the only exception to one-byte encoding.
