Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rguenth at gcc dot gnu.org Target Milestone|--- |5.0 --- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- I suppose -flto is the same as -fwhole-program then?
