When generating a switch for: case e of 0 -> A 1 -> B instead of generating if (e < 1) then goto A B generate if (e >= 1) then goto B A because this helps the NCG to generate better code. In particular, if e is a comparison, then we don't need to reverse the sense of the comparison to eliminate the comparse against 1 (the NCG does try to reverse the comparison, but floating-point comparisons can't be reversed).
