--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The update_ssa call is very wrong, you just can't do that for every gimple
backend builtin call you fold, you could have millions of them and update_ssa
is a global whole function expensive function.
Either one doesn't ensure vops are properly updated and queues a
TODO_update_ssa_only_virtuals or so at the end of a pass, or one makes sure to
update it properly.  For the gimple folder, I think only the second option is
reasonable...
