https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91200 --- Comment #2 from Richard Biener --- So we're applying cselim to if (a.0_1 != 0) goto ; [50.00%] else goto ; [50.00%] [local count: 766958447]: # i_20 = PHI h[i_20] = &c; [local count: 168730858]: # i_21 = PHI where bb3 has only a single stmt but the PHI node precludes simply inserting the stmt elsewhere. The PHI node is left from non-iterating FRE which isn't able to do all simplification in one go.
