Thanks, good catch on the cmp especially. Is there any need for the 4: label, do you think? I guess you already noticed we have to use movs instead of mov for that immediate load; the old asm.S loaded a literal from a constant pool but I think this way is a little quicker and takes a little less space.

I guess not since it's not actually used.
