Yes, as discussed earlier (but perhaps lost in other coments) we need
fix for the targetm.calls.empty_record_p (type) divergence. It is not
clear to me if simply calling the default implementation instead of the
rather complicated conditional
if (TYPE_EMPTY_P (rhstype)
|| (RECORD_OR_UNION_TYPE_P (rhstype)
&& (!first_field (rhstype)
|| default_is_empty_record (rhstype))))
return NULL_TREE;
is desired here, so hope Martin Sebor will know. Perhaps simply
exporting default_is_empty_type and doing
if (default_is_empty_type (rhstype))
return NULL_TREE;
