	* g++.dg/compat/struct-layout-1_generate.c: Avoid generating
	further fields after the first flexible array member.
	* g++.dg/ext/flexary2.C: Expect a sole flexible array member
	to be rejected.  Add a test case exercising zero-length array.
	* g++.dg/ext/flexary3.C: Expect a sole flexible array member
	to be rejected.
	* g++.dg/ext/flexary.h: New file.

	* g++.dg/other/dump-ada-spec-2.C: Adjust to reflect flexible
	array members.
	* g++.dg/parse/pr43765.C: Add a member to make a struct with
	a flexible array member valid.  Adjust expected error message.
	* g++.dg/torture/pr64280.C: Expect a sole flexible array member
	to be rejected.
	* g++.dg/torture/pr64312.C: Add a member to make a struct with

	* class.c (walk_subobject_offsets): Avoid assuming type domain
	is non-null or has an upper bound.

	* decl.c (compute_array_index_type): Distinguish flexible array
	members from zero-length arrays.
	(grokdeclarator): Reject flexible array members in unions.  Avoid
	rejecting members of incomplete types that are flexible array members.
	* error.c (dump_type_suffix): Handle flexible array members with null
	upper bound.
	* init.c (perform_member_init): Same.
	* pt.c (instantiate_class_template_1): Allow flexible array members.

	array members.

	c++/42121
	* tree-chkp.c (chkp_find_bound_slots_1): Handle flexible array
	members.
	* tree.c (type_contains_placeholder_1): Avoid assuming type has
	a non-null domain or an upper bound to handle flexible array
	members.
	* varasm.c (output_constructor_regular_field):  Same.
	(output_constructor): Set min_index to integer_zero_node rather
	than null when a type has no domain to avoid crashing later.
