--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
There is redirect_to_unreachable and a couple of other places (though at le=
ast
half of them are related to devirtualization which shouldn't be happening
here):
grep builtin_decl_unreachable ipa*
ipa.cc:     target =3D cgraph_node::get_create (builtin_decl_unreachable ()=
);
ipa-fnsummary.cc:    =3D cgraph_node::get_create (builtin_decl_unreachable =
());
ipa-prop.cc:      target =3D builtin_decl_unreachable ();
ipa-prop.cc:  tree new_target =3D builtin_decl_unreachable ();
So, I'd add a breakpoint on builtin_decl_unreachable and see where it is ca=
lled
for this code.=
