--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note I think late_combine 1 depends on DCE later on to delete the noop_move_p instructions but since -fno-dce was passed on the command line, it is not deleted and that causes the ICE. Note also I think this only happens with -fno-dce it can't happen otherwise.
