--- Comment #8 from Andrew Pinski <pinskia at gcc dot gnu.org> --- _25 = google::protobuf::internal::TcParser::MiniParse (msg_14(D), pretmp_68, ctx_21(D), table_16(D), hasbits_15(D), data); [must tail call] goto <bb 15>; [100.00%] <bb 15> [count: 1073741824]: # _10 = PHI <ptr_40(9), _25(11), _23(14)> return _10; Maybe another empty EH issue ... because optimized looks like it could be a tail call'ed just fine.
