--- Comment #12 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is still true as far as I can tell by reading the code.
The case where it will happen is REAL_MODE_FORMAT does not have a simple sign
bit or 

GET_MODE_SIZE (mode) <= UNITS_PER_WORD && the mode does not exist

Which I think the first is true for IBM 128bit long doubles.

Note I don't know if IBM 128bit long double is an important use case.
