--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-02-01 14:01:09 UTC --- Created attachment 26543 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26543 gcc47-pr52079.patch Alternate patch for the GO FE. There are hundreds of other lang_hooks.types.type_for_mode callers, so this variant seems to be safer to me, at least at this point.
