--- Comment #7 from Segher Boessenkool <segher at gcc dot gnu.org> --- Ah, -fdump-ipa-all-all . So it seems like ppc-round.c.072i.icf is what is wrong; it says Equals called for: round_float_uint/3:round_float_int/1 with result: true Equals called for: round_double_uint/2:round_double_int/0 with result: true (that is the first thing wrong I see).
