--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
As the functions aren't constexpr, they aren't even considered during C++ FE
constexpr processing. gnu::const means something completely different.
I bet we optimize away static const variables only written (even with
non-constant initializers) and never address taken or otherwise used, this PR
seems to ask to handle inline const (with the C++ FE specific behavior for
them) in such cases too.
I'm not sure it is valid if the vars are odr-used somewhere and the odr-uses
are later optimized away, I think emitting the inline vars in that case is part
of the ABI. And the not odr-used cases which are only used by their
initialization is yet another question.
