Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Comment on attachment 52289 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52289 Tentative patch I'm not sure this will work properly, I think in C _Float128 is a distinct type, so in _Generic it will probably not match __float128. I think libgfortran uses __float128, not _Float128. Shouldn't the __float128 stuff be guarded with defined(GFC_REAL_16_IS_FLOAT128) || defined(HAVE_GFC_REAL_17) ?
