(1) CR (EQUIVALENT)
Case Reductions:
The following Case expression
"case compare x y of {
EQ  -> o;
LT  -> LT;
GT  -> GT}
"
is transformed to
"primCompAux0 o EQ = o;
primCompAux0 o LT = LT;
primCompAux0 o GT = GT;
"

(2)
Obligation:
mainModule Main 
module Main where {
import qualified Prelude;

----------------------------------------

(3) IFR (EQUIVALENT)
If Reductions:
The following If expression
"if primGEqNatS x y then Succ (primDivNatS (primMinusNatS x y) (Succ y)) else Zero"
is transformed to
"primDivNatS0 x y True = Succ (primDivNatS (primMinusNatS x y) (Succ y));
primDivNatS0 x y False = Zero;
"
The following If expression
"if primGEqNatS x y then primModNatS (primMinusNatS x y) (Succ y) else Succ x"
is transformed to
"primModNatS0 x y True = primModNatS (primMinusNatS x y) (Succ y);
primModNatS0 x y False = Succ x;
