--- Comment #21 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Richard Biener from comment #19) > I'll cook up a preliminary patch for the Q vs. f128 change. Note it seems libgfortran LIBGFOR_CHECK_FLOAT128 sets USE_IEC_60559 in odd ways, also requiring Q literal suffix support. So for targets with native _Float128 support using the f128 suffix would have been better? But why does s390x reject Q. Anyway, post-poning this after the libquadmath check/support is in since for libgfortran this is where the USE_IEC_60559 is defined.
