--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Looks like ivopts. In message_info_load, ivopts dumps are the first ones to contain differences like <bb 19> [local count: 955630198]: - # _172 = PHI <_32(59), 0(56)> # _173 = PHI <_33(59), label_117(56)> # _174 = PHI <_34(59), _169(56)> # label_179 = PHI <label_49(59), label_117(56)> - # ivtmp.411_35 = PHI <ivtmp.411_57(59), 1(56)> + # ivtmp.410_35 = PHI <ivtmp.410_57(59), 1(56)> + _172 = ivtmp.410_35 + 18446744073709551615; and <bb 23> [local count: 324914271]: part.22_28 = part; - _29 = _172 + 1; + _29 = ivtmp.410_35; label_124 = part.22_28 + _29; and part.24_31 = part; - _32 = ivtmp.411_35; + _32 = ivtmp.410_35; _33 = part.24_31 + _32; _34 = *_33; - ivtmp.411_57 = ivtmp.411_35 + 1; + ivtmp.410_57 = ivtmp.410_35 + 1; I only see added # DEBUG lines in slp1.
