Add `CaseApply` optimization #7421

SeungheonOh · 2025-11-15T07:37:37Z

Adds "application through case/constr" optimization. Pretty decent free optimizations.

It is also possible to turn programs like

[(lam x [(lam y [(lam z z) (con integer 1)]) (con integer 2)]) (con integer 3)]

into

(case (constr 0 (con integer 1) (con integer 2) (con integer 3)) (lam x (lam y (lam z))))

But this is only possible when the body of inner lambda doesn't reference variable bounded by all previous lambda abstractions. Maybe this is easier to do on PIR side.

I don't understand how this is an optimisation. Can you explain the logic behind it?

Basically, applying arguments using Case/Constr is cheaper because it can apply any number of arguments in one AST node.

It is also possible to turn programs like
[(lam x [(lam y [(lam z z) (con integer 1)]) (con integer 2)]) (con integer 3)]
into
(case (constr 0 (con integer 1) (con integer 2) (con integer 3)) (lam x (lam y (lam z))))
But this is only possible when the body of inner lambda doesn't reference variable bounded by all previous lambda abstractions. Maybe this is easier to do on PIR side.

Are there any tests that display this behaviour?

I'd actually expect that it would transform into

(case (constr 0 (con integer 3) (con integer 2) (con integer 1)) (lam x (lam y (lam z. z))))
