--- Comment #12 from Segher Boessenkool <segher at gcc dot gnu.org> ---
When is the lowering done currently?  Only for the ops that have no other way
of doing, and things are merged back to an __int128 immediately after that?

If that is what is going on, then that is unfortunate, but it may the best
we can do yes.  Sigh.
