--- Comment #5 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
Agreed that this needs a new attribute, and digging through the macros used to
guard the associated patterns, this really does need to be restricted to the
case when long double is implemented by IBM-128.  Safest is to use
FLOAT128_2REG_P (TFmode), i.e., applied to the mode used for long double, which
is what enables the corresponding pack<mode> and unpack<mode> patterns.
