--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
We do have DECL_DECLARED_INLINE_P flag, but that is set even with just
constexpr keyword.
For the cases we were discussing on IRC, functions which should be constexpr
e.g. in C++20 and not in C++17 and earlier, but which should still have comdat
semantics, but not be really suggested as better idea for inlining, I think we
want an attribute, but as constexpr is something that is done very often, it
might be best to have another generic FUNCTION_DECL bit next to
DECL_DECLARED_INLINE_P, which the new attribute (something in between noinline
on inline function and always_inline) would clear and we'd clear it on
constexpr functions that aren't explicitly inline too?
