--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
And to avoid repeated scanning of DECL_INITIAL when we add more of these
patterns we could record classification of the table in a custom
internal decl attribute we add, __attribute__(("table kind"(int)))
with an enum also recording "unknown" so we scan at most once.
