-	* exp_attr.adb (Expand_N_Attribute_Reference): In the case of a
-	Reduce attribute reference, fix bugs in initializing Accum_Typ.
-	The previous version was incorrect in the case where E1 refers to

-	version also had code to compute Accum_Typ via a different method
-	if the initial computation turned out to yield a universal numeric
-	type. Delete that initial computation and use the second method in
-	all cases.
-
-2023-11-28  Gary Dismukes  <dismukes@adacore.com>

-	discriminant-dependent box-defaulted subcomponent of a nonprivate
-	record type with discriminants, and handle all top-level
-	components that have a non-null base init proc directly, by
-	calling Add_Association with "Is_Box_Present => True". Also,
-	combine that elsif clause with the immediately preceding elsif
-	clause, since they now both contain the same statement (calls to
-	Add_Association with the same actuals).

-	* sem_aggr.adb (Resolve_Delta_Array_Aggregate): In the case of a
-	deep delta choice, the expected type for the expression will
-	typically not be the component type of the array type, so a call
-	to Analyze_And_Resolve that assumes otherwise would be an error.
-	It turns out that such a call, while wrong, is usually harmless
-	because the expression has already been marked as analyzed. This
-	doesn't work if the aggregate occurs in a postcondition and, in
-	any case, we don't want to rely on this. So do not perform the
-	call in the deep case.

-	switches the aspects between the new and the old node it is no

-	(Has_Aspects): Converted to a utility method that performs the same

-	* gen_il-fields.ads: Remove Has_Aspects and add
-	Aspect_Specifications fields.
-	* gen_il-gen-gen_nodes.adb: Add Aspect_Specification fields
-	for all nodes that can have aspects. Additionally add
-	Expression_Copy for Aspect_Speficiations to avoid reusing
-	the Associated_Node for generic instantiation and aspect
-	analysis.
-	* ghost.adb (Remove_Ignored_Ghost_Node): Remove call to Remove_Aspects.
-	The rewritten node is a Null_Statement that cannot have aspects
-	and there is not anything to gain from removing them from the

-
-	* local_restrict.ads: A new package. Declares Local_Restriction
-	enumeration type and provides operations to check for local
-	restriction violations.
-	* local_restrict.adb: Corresponding package body. Replace "not
-	Present (X)" calls with "No (X)" calls.
-	* aspects.ads: Add a new enumeration elements,
-	Aspect_Local_Restrictions and Aspect_User_Aspect, to the Aspect_Id
-	enumeration type. Update Aspect_Id-indexed aggregates. Add nested
-	package User_Aspect_Support to manage two pieces of state. One is
-	a map from identifiers to User_Aspect_Definition pragmas (updated
-	when such a pragma is encountered). The other is an
-	access-to-subprogram variable that is introduced in order to keep
-	the bulk of semantics out of the closure of package Aspects while
-	allowing a call from aspects.adb to the sem_ch13 procedure that
-	analyzes a User_Aspect aspect specification.
-	* aspects.adb (Find_Aspect): Cope with a case of a block statement
-	with an empty parent. It is not clear whether this is papering
-	over a compiler bug. Add indirect call through the aforementioned
-	access-to-subprogram variable when Find_Aspect enounters an
-	unanalyzed User_Aspect aspect specification. If Find_Aspect is
-	called looking for aspect Foo, then a User_Aspect specification
-	might generate (during analysis) a Foo aspect specification. So
-	the Find_Aspect call needs to trigger that analysis if it has not
-	already taken place. Provide a body for package
-	User_Aspect_Support. Replace "not Present (X)" call with "No (X)"
-	call.
-	* freeze.adb (Freeze_Subprogram): Check local restriction
-	compatibility when a dispatching operation is overridden.
-	* par-prag.adb: Add support for parsing a User_Aspect_Definition
-	pragma.
-	* restrict.ads: We'd like to have the body of package Restrict
-	include a call to a procedure declared in package Local_Restrict.
-	Doing that in the obvious way pulls most of semantics into the
-	closure of package Restrict, and that turns out to cause problems.
-	So we introduce a level of indirection and instead call through an
-	access-to-subprogram value. In this unit, we declare the
-	access-to-subprogram type and object.
-	* restrict.adb (Check Restriction): When a construct is
-	encountered that could violate a global restriction (depending on
-	whether the given restriction is in effect), Check_Restriction is
-	called. At this point, we also check for a violation of any
-	corresponding local restriction that is in effect. For reasons
-	described above, this check is performed via an indirect call.
-	* sem_ch13.ads (Parse_Aspect_Local_Restrictions): A new function,
-	similar to the existing Parse_Aspect_Xxx subprograms.
-	* sem_ch13.adb: Perform semantic analysis of Local_Restrictions
-	and User_Aspect aspect specifications. Declare and call new
-	Validate_Aspect_Local_Restrictions and
-	Analyze_User_Aspect_Aspect_Specification procedures (a reference
-	to the latter is registered during package elaboration). In
-	Analyze_Aspect_Specifications, do not set the Analyzed flag of a
-	User_Aspect aspect specification. Replace "not Present (X)" call
-	with "No (X)" call. Replace 'Image with 'Img in a case where the
-	prefix of the attribute reference is an object; this is done to
-	accomodate older compilers.
-	* sem_ch6.adb (Check_Subtype_Conformant): Include in subtype
-	conformance check a check for overriding-related compatibility of
-	local restrictions.
-	* sem_ch8.adb (Analyze_Subprogram_Renaming): In the case of an
-	instance of a generic that takes a formal subprogram, check that
-	formal and actual are compatible with respect to local
-	restrictions.
-	* sem_prag.adb: Add support for User_Aspect_Definition pragma.
-	* sem_res.adb (Resolve_Call): Check caller/callee compatibility
-	with respect to local restrictions.
-	* snames.ads-tmpl: Add Name_Local_Restrictions, Name_User_Aspect,

-	then we would typically go up to its declaration, and then back
-	down to the Defining_Entity of the declaration, which is N itself.
-	There were other cases where Find_Enclosing_Scope of an entity
-	disagreed with Scope. Clearly, Find_Enclosing_Scope and Scope
-	should agree (when both are defined). Such bugs caused latent bugs
-	in accessibility.adb related to 'Old, and fixing bugs here caused
-	such bugs to be revealed. These are fixed by calling Scope when N
-	is an entity.

+	switches the aspects between the new and the old node it is no

+	a node actually has aspects or not.
+	(Copy_Aspects): New utility method that performs a deep copy of the

+	* gen_il-gen-gen_nodes.adb: Add Aspect_Specification fields
+	for all nodes that can have aspects. Additionally add
+	Expression_Copy for Aspect_Speficiations to avoid reusing
+	the Associated_Node for generic instantiation and aspect
+	analysis.
+	* ghost.adb (Remove_Ignored_Ghost_Node): Remove call to Remove_Aspects.
+	The rewritten node is a Null_Statement that cannot have aspects
+	and there is not anything to gain from removing them from the
+	Orignal_Node of N since it technically is not part of the active
+	tree.
+	* inline.adb (Process_Formals_In_Aspects): Simplify code for node traversal.

+	* sem_ch13.adb (Analyze_Aspect_Specifications): Add early return to simplify

+
+	* local_restrict.ads: A new package. Declares Local_Restriction
+	enumeration type and provides operations to check for local
+	restriction violations.
+	* local_restrict.adb: Corresponding package body. Replace "not
+	Present (X)" calls with "No (X)" calls.
+	* aspects.ads: Add a new enumeration elements,
+	Aspect_Local_Restrictions and Aspect_User_Aspect, to the Aspect_Id
+	enumeration type. Update Aspect_Id-indexed aggregates. Add nested
+	package User_Aspect_Support to manage two pieces of state. One is
+	a map from identifiers to User_Aspect_Definition pragmas (updated
+	when such a pragma is encountered). The other is an
+	access-to-subprogram variable that is introduced in order to keep
+	the bulk of semantics out of the closure of package Aspects while
+	allowing a call from aspects.adb to the sem_ch13 procedure that
+	analyzes a User_Aspect aspect specification.
+	* aspects.adb (Find_Aspect): Cope with a case of a block statement
+	with an empty parent. It is not clear whether this is papering
+	over a compiler bug. Add indirect call through the aforementioned
+	access-to-subprogram variable when Find_Aspect enounters an
+	unanalyzed User_Aspect aspect specification. If Find_Aspect is
+	called looking for aspect Foo, then a User_Aspect specification
+	might generate (during analysis) a Foo aspect specification. So
+	the Find_Aspect call needs to trigger that analysis if it has not
+	already taken place. Provide a body for package
+	User_Aspect_Support. Replace "not Present (X)" call with "No (X)"
+	call.
+	* freeze.adb (Freeze_Subprogram): Check local restriction
+	compatibility when a dispatching operation is overridden.
+	* par-prag.adb: Add support for parsing a User_Aspect_Definition
+	pragma.
+	* restrict.ads: We'd like to have the body of package Restrict
+	include a call to a procedure declared in package Local_Restrict.
+	Doing that in the obvious way pulls most of semantics into the
+	closure of package Restrict, and that turns out to cause problems.
+	So we introduce a level of indirection and instead call through an
+	access-to-subprogram value. In this unit, we declare the
+	access-to-subprogram type and object.
+	* restrict.adb (Check Restriction): When a construct is
+	encountered that could violate a global restriction (depending on
+	whether the given restriction is in effect), Check_Restriction is
+	called. At this point, we also check for a violation of any
+	corresponding local restriction that is in effect. For reasons
+	described above, this check is performed via an indirect call.
+	* sem_ch13.ads (Parse_Aspect_Local_Restrictions): A new function,
+	similar to the existing Parse_Aspect_Xxx subprograms.
+	* sem_ch13.adb: Perform semantic analysis of Local_Restrictions
+	and User_Aspect aspect specifications. Declare and call new
+	Validate_Aspect_Local_Restrictions and
+	Analyze_User_Aspect_Aspect_Specification procedures (a reference
+	to the latter is registered during package elaboration). In
+	Analyze_Aspect_Specifications, do not set the Analyzed flag of a
+	User_Aspect aspect specification. Replace "not Present (X)" call
+	with "No (X)" call. Replace 'Image with 'Img in a case where the
+	prefix of the attribute reference is an object; this is done to
+	accomodate older compilers.
+	* sem_ch6.adb (Check_Subtype_Conformant): Include in subtype
+	conformance check a check for overriding-related compatibility of
+	local restrictions.
+	* sem_ch8.adb (Analyze_Subprogram_Renaming): In the case of an
+	instance of a generic that takes a formal subprogram, check that
+	formal and actual are compatible with respect to local
+	restrictions.
+	* sem_prag.adb: Add support for User_Aspect_Definition pragma.
+	* sem_res.adb (Resolve_Call): Check caller/callee compatibility
+	with respect to local restrictions.
+	* snames.ads-tmpl: Add Name_Local_Restrictions, Name_User_Aspect,
+	and Name_User_Aspect_Definition constants.
+	* doc/gnat_rm/implementation_defined_aspects.rst: Document new
+	aspects.
+	* doc/gnat_rm/implementation_defined_pragmas.rst: Document new
