--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
And there is another thing, we need to check all these
gimple_build_builtin_unreachable and builtin_decl_unreachable and
build_builtin_unreachable calls and check if any of them aren't done during=
 IPA
with the assumed new caller not being set as cfun.  Because those functions
test
flag_* etc. vars and if there would be such calls, we'd need to pass struct
function * and use opts_for_fn instead of flag_*.=
