--- Comment #16 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #15) > We are using that #c13 patch successfully for almost 18 months now in Fedora. > As type promotion/demotion patch is not (sadly) going to happen for GCC 5, I > still think it would be worthwhile to apply it temporarily, until type > promotion/demotion is written. Works for me.
