For this reason I added flag to cfg structure tracking this. This patch broke a couple of _BitInt tests (in the admittedly still uncommitted series - still waiting for review of the C FE bits). Here is a minimal patch to make it work again, though I'm not sure if in the if_then_else and if_then_if_then_else cases I shouldn't scale count of the other bbs as well. if_then method creates if (COND) new_bb1; in a middle of some pre-existing bb (with PROB that COND is true), if_then_else if (COND) new_bb1; else new_bb2; and if_then_if_then_else if (COND1) { if (COND2) new_bb2; else new_bb1; } with PROB1 and PROB2 probabilities that COND1 and COND2 are true. The lowering happens shortly after IPA. 2023-09-06 Jakub Jelinek <ja...@redhat.com> PR c/102989 * gimple-lower-bitint.cc (bitint_large_huge::if_then_else, bitint_large_huge::if_then_if_then_else): Use make_single_succ_edge rather than make_edge, initialize bb->count.
