--- Comment #14 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
And as for the define_insn_and_split without constraints that don't expect to
be matched post split1, I think we can try to figure out something
incrementally and change all of them at once, e.g. a property set by expand
pass and cleared by split1 pass, or property set by split1 pass or something
similar.
