It's not an implementation detail, because the decoder runs before the execution of every instruction. If we're going to say that NOP increments IP by one, then we should also say that ADD "stores in dst the addition of src and dst, as well as incrementing IP by the length of the instruction", and JMP imm "increments JMP by imm + the length of the instruction".
- loeg 2mo agoADD does in fact do that.
- fluoridation 2mo agoI'm not disputing the total effect. I'm asking if you'd rather describe ADD and JMP in this manner, in order to say that NOP does not in fact do nothing.
- dxdm 2mo agoLove the pedantry here. I'm currently at: no op code does anything, it's all fancy effects in the hardware that can be described in arbitrary detail, which somehow allows me to cause these letters to appear on your screen.
- fluoridation 2mo agoInsightful and compelling. Tell me another one.

And then one day A magic day he passed my way And while we spoke of many things Fools and kings This he said to me: "The greatest thing you'll ever learn Is just to love and be loved in return."
