--- Comment #21 from chenglulu <chenglulu at loongson dot cn> --- (In reply to Jakub Jelinek from comment #18) > _Float128 is definitely not for backward compatibility, it is a standard C23 > type and in C++ used for the standard std::float128_t type. > I think aarch64 doesn't build libquadmath either, but maybe it only supports > long double and _Float128/f128 and not __float128/Q. Aarch64 supports Q suffix but not __float128.
