--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note on x86, XFmode has mode_to_bits which is 128 or 96 but precision is 80.

So changing mode_to_bits to return precision is 100% the wrong thing.

So the bug might be the case there is a place which is using GET_MODE_BITSIZE
but should be using GET_MODE_PRECISION . But changing GET_MODE_BITSIZE to be
the same GET_MODE_PRECISION is wrong.
