--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Seems one of the issues is that array_of_runtime_bound_p only looks at the
toplevel array.  Shall it look at all the nested ARRAY_TYPEs and return true if
any of them is of runtime bound?  Or shall we have another predicate which
would do that?  There is always variably_modified_type_p predicate, but it
doesn't probably work too well with dependent types.
