--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
But even hashing DECL_UIDs rather than hashing pointers is a no-go here,
pointers can be arbitrary, for DECL_UIDs we at least have the guarantee that -g
and -g0 DECL_UIDs compare the same, but there can be bigger gaps in between
them for -g.  Dunno if symtab_node's order field can be used reliably for this
or not (or it could hash ->name () string).
