Hi Anto, hi Ademan, On Sat, Mar 19, 2011 at 10:07 AM, Antonio Cuni <anto.c...@gmail.com> wrote: > what happens when you are on 32 bit and see int_add(i0, -2147483648)?
It probably works, because -(-2147483648) == -2147483648, and int_add(i0, -2147483648) and int_sub(i0, -2147483648) do the same thing. However I have no clue why this replacement is giving you anything. If anything at all I would say that replacing int_add(i0, -128) with int_sub(i0, 128) is a (very marginally) bad idea on x86 because the constant -128 fits in 8 bits but the constant 128 doesn't. Well, I suppose that "it makes it easier for me, the human, to understand it" is a valid reason after all.
