It fixes the IPA ICF dump difference though (the :370 vs. :371 "issue") remains. The .fixup_cfg LTRANS dump debug stmt differences remain as well. The same ltrans unit at .optimized has additional code-gen differences: <bb 83> [local count: 56209456]: # _462 = PHI <_354(182), _122(177), _354(184)> - # would_overrun_p_183 = PHI <would_overrun_p_11(182), would_overrun_p_468(177), 1(184)> + # would_overrun_p_183 = PHI <would_overrun_p_11(182), would_overrun_p_468(177), _448(184)> # _218 = PHI <_375(182), 1(177), _375(184)>
