hello my knowledgable friends :)
i have recently been talking about opcode decoding, and wanted to confirm that instructions for 64bit registers will take longer for the processor to decode.
thanks :) i am unable to find definitive documentation about it.

Hm, aren't the MOV opcodes in long mode the same as in short mode? If so, I can't see why decoding should take longer time.
