	* sem_ch3.ads, sem_ch3.adb (Build_Discriminal): Add link to original
	discriminant.
	(Build_Private_Derived_Type): The entity of the created full view of the
	derived type does not come from source. If after installing the private
	declarations of the parent scope the parent is still private, use its
	full view to construct the full declaration of the derived type.
	(Build_Derived_Record_Type): Relax the condition that controls the
	execution of the check that verifies that the partial view and
	the full view agree in the set of implemented interfaces. In
	addition, this test now only takes into account the progenitors.
	(Derive_Interface_Subprograms): No need to derive subprograms
	of ancestors that are interfaces.
	(Derive_Subprograms): Remove formal No_Predefined_Prims and the
	associated code.

	view is a transitive derivation of the ancestor of the partial view.
	(Process_Full_View): Rename local subprogram Find_Interface_In_
	Descendant to Find_Ancestor_Interface to leave the code more clear.
	Remove wrong code that avoids the generation of an error message
	when the immediate ancestor of the partial view is an interface.
	In addition some minor reorganization of the code has been done to
	leave it more clear.
	(Analyze_Type_Declaration): If type has previous incomplete tagged
	partial view, inherit properly its primitive operations.
	(Collect_Interfaces): Make public, for analysis of formal
	interfaces.
	(Analyze_Interface_Declaration): New procedure for use for regular and
	formal interface declarations.
	(Build_Derived_Record_Type): Add support for private types to the code
	that checks if a tagged type implements abstract interfaces.
	(Check_Aliased_Component_Type): The test applies in the spec of an
	instance as well.
	(Access_Type_Declaration): Clean up declaration of malformed type
	declared as an access to its own classwide type, to prevent cascaded
	crash.
	(Collect_Interfaces): For private extensions and for derived task types
	and derived protected types, the parent may be an interface that must
	be included in the interface list.
	(Access_Definition): If the designated type is an interface that may
	contain tasks, create Master_Id for it before analyzing the expression
	of the declaration, which may be an allocator.
	(Record_Type_Declaration): Set properly the interface kind, for use

	Retrieve the N_Package_Instantiation node when the Package_Instantiation
	field is present.
	(Check_Generic_Child_Unit): Within an inlined call, the only possible
	instantiation is Unchecked_Conversion, for which no parents are needed.
	(Inline_Instance_Body): Deinstall and record the use_clauses for all
	parent scopes of a scope being removed prior to inlining an instance
	body.
	(Analyze_Package_Instantiation): Do not perform front-end inlining when
	the current context is itself an instance within a non-instance child
	unit, to prevent scope stack errors.
	(Save_References): If the node is an aggregate that is an actual in a
	call, rewrite as a qualified expression to preserve some type
	information, to resolve possible ambiguities in the instance.
	(Instance_Parent_Unit): New global variable to record the ultimate
	parent unit associated with a generic child unit instance (associated
	with the existing Parent_Unit_Visible flag).
	(type Instance_Env): New component Instance_Parent_Unit for stacking
	parents recorded in the global Instance_Parent_Unit.
	(Init_Env): Save value of Instance_Parent_Unit in the Instance_Env
	stack.
	(Install_Spec): Save the parent unit entity in Instance_Parent_Unit when
	it's not a top-level unit, and only do this if Instance_Parent_Unit is
	not already set. Replace test of Is_Child_Unit with test of parent's
	scope against package Standard. Add comments and a ??? comment.
	(Remove_Parent): Revise condition for resetting Is_Immediately_Visible
	on a child instance parent to test that the parent equals
	Instance_Parent rather than simply checking that the unit is not a
	child unit.
	(Restore_Env): Restore value of Instance_Parent_Unit from Instance_Env.
	(Validate_Derived_Interface_Type_Instance): Verify that all ancestors of
	a formal interface are ancestors of the corresponding actual.
	(Validate_Formal_Interface_Type): Additional legality checks.
	(Analyze_Formal_Derived_Interface_Type): New procedure to handle formal
	interface types with ancestors.
	(Analyze_Formal_Package): If formal is a renaming, use renamed entity
	to diagnose attempts to use generic within its own declaration.

	* decl.c:
	Factor common code to build a storage type for an unconstrained object
	from a fat or thin pointer type and a constrained object type.
	(annotate_value): Handle BIT_AND_EXPR.
	(annotate_rep): Don't restrict the back annotation of inherited
	components to the type_annotate_only case.
	(gnat_to_gnu_entity) <E_Array_Type>: Do not invoke create_type_decl if
	we are not defining the type.
	<E_Record_Type>: Likewise.
	(gnat_to_gnu_entity) <object, renaming>: Adjust comments and structure
	to get advantage of the new maybe_stabilize_reference interface, to
	ensure that what we reference is indeed stabilized instead of relying
	on assumptions on what the stabilizer does.
	(gnat_to_gnu_entity) <E_Incomplete_Type>: If the entity is an incomplete
	type imported through a limited_with clause, use its non-limited view.
	(Has_Stdcall_Convention): New macro, to centralize the Windows vs others
	differentiation.
	(gnat_to_gnu_entity): Use Has_Stdcall_Convention instead of a spread mix
	of #if sections + explicit comparisons of convention identifiers.
	(gnat_to_gnu_entity) <E_Variable>: Decrement force_global if necessary
	before early-returning for certain types when code generation is
	disabled.
	(gnat_to_gnu_entity) <object>: Adjust comment attached to the
	nullification of gnu_expr we do for objects with address clause and
	that we are not defining.
	(elaborate_expression_1): Do not create constants when creating
	variables needed by the debug info: the dwarf2 writer considers that
	CONST_DECLs is used only to represent enumeration constants, and emits
	nothing for them.
	(gnat_to_gnu_entity) <object>: When turning a non-definition of an
	object with an address clause into an indirect reference, drop the
	initializing expression.
	Include "expr.h".
	(STACK_CHECK_BUILTIN): Delete.
	(STACK_CHECK_PROBE_INTERVAL): Likewise.
	(STACK_CHECK_MAX_FRAME_SIZE): Likewise.
	(STACK_CHECK_MAX_VAR_SIZE): Likewise.
	(gnat_to_gnu_entity): If gnat_entity is a renaming, do not mark the tree
	corresponding to the renamed object as ignored for debugging purposes.

	* trans.c (tree_transform, case N_Attribute_Reference, case Attr_Size &
	related): For a prefix that is a dereference of a fat or thin pointer,
	if there is an actual subtype provided by the front-end, use that
	subtype to build an actual type with bounds template.
	(tree_transform, case N_Free_Statement): If an Actual_Designated_Subtype
	is provided by the front-end, use that subtype to compute the size of
	the deallocated object.
	(gnat_to_gnu): When adding a statement into an elaboration procedure,
	check for a potential violation of a No_Elaboration_Code restriction.
	(maybe_stabilize_reference): New function, like gnat_stabilize_reference
	with extra arguments to control whether to recurse through non-values
	and to let the caller know if the stabilization has succeeded.
	(gnat_stabilize_reference): Now a simple wrapper around
	maybe_stabilize, for common uses without restriction on lvalues and
	without need to check for the success indication.
	(gnat_to_gnu, call_to_gnu): Adjust calls to gnat_stabilize_reference, to
	pass false instead of 0 as the FORCE argument which is a bool.
	(Identifier_to_gnu): Remove checks ensuring that an renamed object
	attached to a renaming pointer has been properly stabilized, as no such
	object is attached otherwise.
	(call_to_gnu): Invoke create_var_decl to create the temporary when the
	function uses the "target pointer" return mechanism.
	Reinstate conversion of the actual to the type of the formal
	parameter before any other specific treatment based on the passing
	mechanism. This turns out to be necessary in order for PLACEHOLDER
	substitution to work properly when the latter type is unconstrained.

	* gigi.h (build_unc_object_type_from_ptr): New subprogram, factoring a
	common pattern.
	(maybe_stabilize_reference): New function, like gnat_stabilize_reference
	with extra arguments to control whether to recurse through non-values
	and to let the caller know if the stabilization has succeeded.

	* utils2.c (gnat_build_constructor): Only sort the fields for possible
	static output of record constructor if all the components are constant.
	(gnat_build_constructor): For a record type, sort the list of field
	initializers in increasing bit position order.
	Factor common code to build a storage type for an unconstrained object
	from a fat or thin pointer type and a constrained object type.
	(build_unary_op) <ADDR_EXPR>: Always recurse down conversions between
	types variants, and process special cases of VIEW_CONVERT expressions
	as their NOP_EXPR counterpart to ensure we get to the
	CORRESPONDING_VARs associated with CONST_DECls.
	(build_binary_op) <MODIFY_EXPR>: Do not strip VIEW_CONVERT_EXPRs
	on the right-hand side.

	* utils.c (build_unc_object_type_from_ptr): New subprogram, factoring
	a common pattern.
	(convert) <VIEW_CONVERT_EXPR>: Return the inner operand directly if we
	are converting back to its original type.
	(convert) <JM input>: Fallthrough regular conversion code instead of
	extracting the object if converting to a type variant.
	(create_var_decl): When a variable has an initializer requiring code
	generation and we are at the top level, check for a potential violation
	of a No_Elaboration_Code restriction.
	(create_var_decl): call expand_decl for CONST_DECLs, to set MODE, ALIGN
	SIZE and SIZE_UNIT which we need for later back-annotations.
	* utils.c: (convert) <STRING_CST>: Remove obsolete code.
	<VIEW_CONVERT_EXPR>: Do not lift the conversion if the target type
	is an unchecked union.
	(pushdecl): Set DECL_NO_STATIC_CHAIN on imported nested functions.
	(convert) <VIEW_CONVERT_EXPR>: When the types have the same
	main variant, just replace the VIEW_CONVERT_EXPR.
	<UNION_TYPE>: Revert 2005-03-02 change.

	* repinfo.h, repinfo.ads: Add tcode for BIT_AND_EXPR.

	* repinfo.adb (Print_Expr, Rep_Value): Handle Bit_And_Expressions.
