From 5eb1fd0dae3832ceee2102613bb08c291daca6f3 Mon Sep 17 00:00:00 2001 From: Santiago Aboy Solanes Date: Tue, 18 Apr 2023 15:16:06 +0100 Subject: Restrict the use of ConstantFolding's VisitIf It was taking a lot of time for the improvement it got. We can get 99.99% of the improvement, with only one VisitIf call. This is roughly 20% of the compile time it used to take.
