does profile guided optimisation reduce these checks?
- porridgeraisin 2mo agoInsofar as PGO helps inlining.
- 5701652400 2mo agoI have hunch PGO does detect when bound check can be eliminated.
- delamon 2mo agoHow so? PGO might indicate that most of the time arguments are in bounds, but that's not enough. It has to be a proof with 100% certainty before bound checks can be removed
- porridgeraisin 2mo agobound check elimination exists separately, PGO can help unveil more opportunities for BCE.
