Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hubicka at gcc dot gnu.org --- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> --- With that reduced testcase, I've bisected it to r208831, before inlining pass there are no differences, and starting with r208831 the inliner changes 3 calls to __builtin_unreachable - __dynamic_cast, AWindow2::isParent and fwrite. Haven't yet looked why the inliner considers those unreachable, if there is some undefined behavior that makes those unreachable, or something else. Honza?
