--- Comment #21 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Hacking generic_type_for in tree-ssa-loop-ivopts.cc to return the pointer type
fixes the issue. But I still am not sure that is valid.

generic_type_for used to return pointer_type_node, see PR 20625
(r0-67159-gd482f417e4445f). But then an integer type due to PR 27865
(r0-76106-g2052721560b232).
