Bernd Schmidt <bernds at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |bernds at gcc dot gnu.org --- Comment #6 from Bernd Schmidt <bernds at gcc dot gnu.org> --- pass_sanopt adds huge amounts of code, so to some degree I think this is expected.
