--- Comment #7 from Segher Boessenkool <segher at gcc dot gnu.org> ---
It is first V2DI in the RTL, which exists just fine (but there is no
such divide insn); then when it is split to two DImode divides, it
just generates div:DI etc., which does not exist for -m32.

So we either should do what is done for a DImode divides during expand
there, or not allow this builtin.
