--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Could you please attach */libgfortran/Makefile */libgfortran/config.h from the build dir before/after that commit? I believe aarch64 has IEEE754 quad long double, doesn't build libquadmath as it isn't needed, doesn't support __float128, does support _Float128 (distinct? but functionally equivalent type to long double), does support f128/F128 suffixes on floating point constants and to my surprise also supports q/Q suffixes on floating point constants (why?).
