+	* einfo.adb (Is_Partial_DIC_Procedure): New function to return

+	procedure by checking the name (to avoid adding a new field).
+	(DIC_Procedure): Add a test that excludes partial DIC procedures
+	from being returned.
+	(Partial_DIC_Procedure): New procedure to return the partial DIC
+	procedure of a type, if it has one (otherwise returns Empty).
+	(Set_DIC_Procedure): Remove check for duplicate DIC procedures.
+	* exp_aggr.adb (Gen_Assign): Generate a call to the type's DIC
+	procedure in the case where an array component is default
+	initialized (due to an association with a box).
+	(Build_Record_Aggr_Code): For an extension aggregate, generate a
+	call to the ancestor type's DIC procedure (if any) when the
+	ancestor part is a subtype mark. For a record component
+	association that was specified with a box (tested for by
+	checking the new flag Was_Default_Init_Box_Association),
+	generate a call to the component type's DIC procedure (if it has
+	one).
+	* exp_ch4.adb (Expand_N_Allocator): When the allocated object is
+	default initialized and the designated type has a DIC aspect,
+	generate a call to the DIC procedure.
+	* exp_util.ads (Build_DIC_Call): Change the formal Obj_Id to
+	name Obj_Name, and change its type from Entity_Id to Node_Id
+	(and update comment).
+	(Build_DIC_Procedure_Body): Add formal Partial_DIC, remove
+	formal For_Freeze, and update comment accordingly.
+	(Build_DIC_Procedure_Declaration): Add formal Partial_DIC and
+	update comment.
+	* exp_util.adb
+	(Build_DIC_Call): Revised to use its Obj_Name (formerly Obj_Id)
+	formal directly rather than calling New_Occurrence_Of on it, to
+	allow arbitrary names to be passed rather than being limited to
+	Entity_Ids.
+	(Build_DIC_Procedure_Body): Call Add_Parent_DICs to generate
+	checks for DICs associated with any parent types, implementing
+	the required "additive" semantics for DICs. When building a DIC
+	procedure body for a partial view (when Partial_DIC is True),
+	call Add_Own_DIC when the type has its own DIC.  In the case of
+	"full" DIC procedures, a call is generated to any partial DIC
+	procedure of the type (unless the procedure has a null body),
+	along with checks for any DICs inherited by the full view.
+	(Build_DIC_Procedure_Declaration): Add handling for partial DIC
+	procedures.  For the suffix of a regular DIC procedure's name,
+	use "DIC" (instead of "Default_Initial_Condition"), and for the
+	suffix of a partial DIC procedure's name, use "Partial_DIC".
+	(Add_DIC_Check): Add the DIC pragma to the list of seen pragmas
+	(Pragmas_Seen).
+	(Add_Inherited_Tagged_DIC): Remove the formals Par_Typ,
+	Deriv_Typ, and Obj_Id, and add formal Expr, which denotes DIC's
+	expression. Remove the call to Replace_References (which is now
+	done in Add_Inherited_DICs).
+	(Add_Inherited_DICs): New procedure to locate a DIC pragma
+	associated with a parent type, replace its references
+	appropriately (such as any current instance references), and add
+	a check for the DIC.
+	(Add_Own_DIC): Add an Obj_Id formal to allow caller to pass the
+	_init formal of the generated DIC procedure.
+	(Add_Parent_DICs): New procedure to traverse a type's parents,
+	looking for DICs associated with those and calling
+	Add_Inherited_DICs to apply the appropriate DIC checks.
+	(Is_Verifiable_DIC_Pragma): Treat pragmas that have an Empty
+	first argument the same as a pragma without any arguments
+	(returning False for that case).
+	* exp_ch3.adb (Init_One_Dimension): Generate calls to the
+	component's DIC procedure when needed.
+	(Possible_DIC_Call): New function nested in Init_One_Dimension
+	to build a call to the array component type's DIC-checking
+	function when appropriate.
+	(Build_Array_Init_Proc): The presence of a DIC on the component
+	type is an additional condition for generating an init proc for
+	an array type.
+	(Build_Init_Statements): When the record component's type has a
+	DIC, and the component declaration does not have an
+	initialization expression, generate a call to the component
+	type's DIC procedure.
+	(Expand_N_Object_Declaration): Modify the call to Build_DIC_Call
+	to pass a new occurrence of the object's defining id rather than
+	the id itself.
+	(Freeze_Type): Only build a type's DIC procedure (if it has one)
+	for types that are not interfaces.
+	* exp_spark.adb (Expand_SPARK_N_Freeze_Type): Remove From_Freeze
+	actual and add a ??? comment.
+	(Expand_SPARK_N_Object_Declaration): Modify call to
+	Build_DIC_Call to pass a new occurrence of the object id rather
+	than the object id itself.
+	* sem_aggr.adb (Resolve_Record_Aggregate): Declare local flag
+	Is_Box_Init_By_Default and set it in cases where the component
+	association has a box and the component is being initialized by
+	default (as opposed to initialized by an initialization
+	expression associated with the component's declaration).
+	(Add_Association): If the association has a box for a component
+	initialized by default, the flag
+	Was_Default_Init_Box_Association is set on the new component
+	association (for later testing during expansion).
+	(Get_Value): Reset Is_Box_Init_By_Default to False.
+	* sem_ch3.adb (Build_Assertion_Bodies_For_Type): Rearrange code
+	to build DIC procedure bodies for a (noninterface) type that
+	Has_Own_DIC (for partial type views) or Has_DIC (for full type
+	views) as appropriate.
+	* sem_ch13.adb (Analyze_Aspect_Specifications,
+	Aspect_Default_Initial_Condition): Add an extra argument to the
+	DIC pragma to denote the type associated with the pragma (for
+	use in Build_DIC_Procedure_Body).
+	* sem_prag.adb (Analyze_Pragma): Allow two arguments for pragma
+	Default_Initial_Condition.  If not already present, add an extra
+	argument denoting the type that the pragma is associated with.
+	* sem_util.adb (Propagate_DIC_Attributes): Retrieve any partial
+	DIC procedure associated with the type and add it to the type's
+	list of subprograms (Subprograms_For_Type).
+	* sinfo.ads (Was_Default_Init_Box_Association): New flag on
+	N_Component_Association nodes.  Add subprograms to get and set
+	flag, as well as updating the documentation.
+	* sinfo.adb (Was_Default_Init_Box_Association): New function to
+	retrieve the corresponding flag (Flag14).
+	(Set_Was_Default_Init_Box_Association): New procedure to set the
+	corresponding flag (Flag14).
