Segher Boessenkool <segher at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |segher at gcc dot gnu.org --- Comment #3 from Segher Boessenkool <segher at gcc dot gnu.org> --- These things would normally be taken care of by combine, but combine of course does not know what the UNSPEC_ADD_CARRY's mean.
