In the Fortran front-end, float128_type_node is defined as the (expectedly unique) floating-point type for which mode_precision is equal to 128 but not equal to LONG_DOUBLE_TYPE_SIZE. That is, it is garanteed that float128_type_node is not long_double_type_node. If fact, if there is a long double type with precision of 128, then float128_type_node is NULL. Would that match the (new) C behavior? I think it does. FX
