Uh, you mean normal operations don't set the sign flag? (I'm just an assembly programmer and am perfectly willing to defer to a compiler writer on such issues, but it seems like a strange assertion...) They certainly do, but in this particular case, the 'decrement' (n - 1) happens to set the zero flag if n is one so we get that comparison for free. We don't have a flag which immediately tells us whether n = 0 however so we have to perform that comparison separately. Not =, no, but we do have 0 (SF) and =0 (ZF) ; if DEC has the dignity to clear OF we could use the single JLE instruction, otherwise we would need to JS then JZ to the same address. Either way we would not need to explicitly CMP anything. I think. (Actually if DEC sets OF properly then that will work just as well as clearing it.) Ah yes, you are right, that does work. it must be something else that is going on here.
