	* sem_ch13.adb (Check_Aspect_At_End_Of_Declarations):
	Ensure the Expression_Copy always has a parent before
	calling any analyze.

2025-07-22  Steve Baird  <baird@adacore.com>

	* exp_aggr.adb (Build_Record_Aggr_Code.Gen_Assign): In the case of
	an aggregate component where the component type is mutably tagged
	and the component value is provided by a qualified aggregate (and
	qualified with a specific type), avoid incorrectly rejecting the
	inner aggregate for violating the rule that the type of an
	aggregate shall not be class-wide.
	* exp_attr.adb: For a predefined streaming operation (i.e., Read,
	Write, Input, or Output) of a class-wide type, the external name
	of the tag of the value is normally written out by Output and read
	in by Input. In the case of a mutably tagged type, this is instead
	done in Write and Read.
	* exp_ch4.adb (Expand_Composite_Equality): In the case of an
	equality comparison for a type having a mutably tagged component,
	we want the component comparison to compare two values of the
	mutably tagged type, not two values of the corresponding
	array-of-bytes-ish representation type. Even if there are no
	user-defined equality functions anywhere in sight, comparing the
	array values still doesn't work because undefined bits may end up
	participating in the comparison (resulting in an incorrect result
	of False).
	* exp_put_image.adb: In the case of a class-wide type, the
	predefined Image attribute includes the name of the specific type
	(and a "'" character, to follow qualified expression syntax) to
	indicate the tag of the value. With the introduction of mutably
	tagged types, this case can now arise in the case of a component
	(of either an enclosing array or an enclosing record), not just
	for a top-level object. So we factor the code to do this into a
	new procedure, Put_Specific_Type_Name_Qualifier, so that it can be
	called from more than one place. This reorganization also involves
	replacing the procedure Put_String_Exp with a new procedure,
	Put_String_Exp_To_Buffer, declared in a less nested scope. For
	mutably tagged components (at the source level) the component type
	(at the GNAT tree level) is an array of bytes (actually a two
	field record containing an array of bytes, but that's a detail).
	Appropriate conversions need to be generated so that we don't end
	up generating an image for an array of bytes; this is done at the
	same places where Put_Specific_Type_Name_Qualifier is called
	(for components) by calling Make_Mutably_Tagged_Conversion.
	* exp_strm.adb (Make_Field_Attribute): Add
	Make_Mutably_Tagged_Conversion call where we construct a
	Selected_Component node and the corresponding component type is
	the internal representation type for a mutably tagged type.
	(Stream_Base_Type): Return the mutably
	tagged type if given the corresponding internal representation type.
	* sem_ch3.adb (Array_Type_Declaration): In the case where the
	source-level component type of an array type is mutably tagged,
	set the Component_Type field of the base type of the declared
	array type (as opposed to that of the first subtype of the array
	type) to the corresponding internal representation type.
	* sem_ch4.adb (Analyze_Selected_Component): In the case of a
	selected component name which references a component whose type is
	the internal representation type of a mutably tagged type,
	generate a conversion to the mutably tagged type.

	that field in the more common cases of an explicit subprogram
	that overrides, to refer to the inherited subprogram that is
	overridden. (Contrary to its name, the Overridden_Operation
	field of the overriding subprogram, which is also set in these

	subprogram is derived.) Also, remove a redundant Present (Alias (S))

	* sem_ch13.adb (Build_Predicate_Function): Add new function

	imposed). If the Predicated_Parent attribute of the given subtype
	is present and refers to a suitable unconstrained subtype, then
	use that subtype instead of setting the Predicated_Parent
	attribute on a new node (and performing the associated attribute
	copying).

2025-06-06  Steve Baird  <baird@adacore.com>

	* sem_ch4.adb
	(Find_Unary_Types): Because we reanalyze names in an instance,
	we sometimes have to take steps to filter out extraneous name
	resolution candidates that happen to be visible at the point of the
	instance declaration. Remove some code that appears to have been
	written with this in mind. This is done for two reasons. First, the
	code sometimes doesn't work (possibly because the In_Instance test
	is not specific enough - it probably should be testing to see whether
	we are in an instance of the particular generic in which the result
	of calling Corresponding_Generic_Type was declared) and causes correct
	code to be rejected. Second, the code seems to no longer be necessary
	(possibly because of subsequent fixes in this area which are not
	specific to unary operators).

	(Check_Function_For_Indexing_Aspect): Procedure renamed from
	Check_One_Function and moved to library level (was nested within
	Check_Indexing_Functions), plus added formals (including Valid, to
	check result). Move scope test to beginning, to immediately exclude
	subprograms not declared immediately within the same scope as the type.
	Improve several error messages. Add error checking for Constant_Indexing
	functions. Append the function entity to the Aspect_Subprograms list of
	the aspect specification. Move code for checking for nonconfirming
	index aspects and for checking for illegal indexing aspects on full
	views to Check_Indexing_Functions.
	(Check_Indexing_Functions): Move procedure Illegal_Indexing from
	here to within Check_Function_For_Indexing_Aspect. Add a comment
	to the loop over interpretations about the checking being done as
	legality rules rather than resolution rules, plus a note referencing
	AI22-0084. Check for nonconfirming indexing aspects and illegal
	indexing aspects on full views here rather than in Check_One_Function
	(now named Check_Function_For_Indexing_Aspect). Remove function
	Check_One_Function (moved to library level and renamed), and call
	Check_Function_For_Indexing_Aspect instead.
	(Check_Inherited_Indexing): Improve spec comment. Remove nested function
	Same_Chars, and replace call Same_Chars with call to Sem_Util.Same_Name.
	Replace call to Illegal_Indexing with call to Error_Msg_NE.
	(Check_One_Function): Unnested from Check_Indexing_Functions, rename
	to Check_Function_For_Indexing_Aspect, move body to library level,
	and move declaration to Sem_Ch13 spec.
	(Analyze_Attribute_Definition_Clause, case Attribute_Default_Iterator):
	Improve error message related to tagged-type requirement. Suppress call
	to Check_Iterator_Functions for attribute definition clauses associated
	with inherited aspects. Remove error checking that is redundant with
	checking done in Check_Iterator_Functions.
	(Check_Aspect_At_Freeze_Point, case Attribute_Default_Iterator): Call
	Check_Iterator_Functions (only if the aspect is not Comes_From_Source).
	(Check_Iterator_Functions): Procedure unnested from
	Analyze_Attribute_Definition_Clause. Add formals Typ and Expr.
	Error messages corrected to say "aspect Default_Iterator" instead of
	"aspect Iterator".
	(Valid_Default_Iterator): Improve error message to say "must be
	a local primitive or class-wide function" instead of "must be
	a primitive function".
	(Check_Primitive_Function): Unnested from Analyze_Attribute_Definition_Clause.
	Add formal Ent.
	(Rep_Item_Too_Late): Return False when an attribute_definition_clause
	is not Comes_From_Source, since it was generated by the compiler (such
	as for an inherited aspect).
	(Resolve_Aspect_Aggregate): Capture implementation base type.
	(Valid_Empty): Use implementation base types for result type comparison.
	(Valid_Add_Named): Use impl base types for comparison of formal's type.
	(Valid_Add_Unnamed): Use impl base types for comparison of formal's type.
	(Valid_New_Indexed): Use impl base types for result type comparison.
	(Validate_Literal_Aspect): Return immediately when aspect does not have
	Comes_From_Source True (no point in validating inherited aspects).
	* sem_res.adb (Has_Applicable_User_Defined_Literal): Remove Base_Type
	comparison and always call Corresponding_Op_Of_Derived_Type for derived
	types. Add "???" comment about issue with wrapper functions (and
	indicate that it would be nice to eliminate the call to
	Corresponding_Primitive_Op).
	* sem_util.ads (Inherit_Nonoverridable_Aspects): New procedure.
	(Corresponding_Op_Of_Derived_Type): Update spec comment to indicate
	return of Ancestor_Op and name changed from Corresponding_Primitive_Op.
	* sem_util.adb (Check_Inherited_Nonoverridable_Aspects): Fix name in
	header comment.
	(Corresponding_Op_Of_Derived_Type): Move declaration of Typ down with
	other local variables. Remove Assert that doesn't apply in some cases.
	Simply return Ancestor_Op when it isn't a primitive (it can be a
	class-wide op). Function name changed from Corresponding_Primitive_Op.
	(Find_Untagged_Type_Of): Add test of Is_Type (E) as a guard for checking
	Direct_Primitive_Operations. Remove Assert (False), and return Empty
	when the primitive is not found.
	(Profile_Matches_Ancestor): Change comparisons to use implementation
	base types of the operations' formal and result types. Add tests for
	interface ancestors. Revise "???" comment.
	(Is_Confirming): Simplify name-matching test to use the names associated
	with the aspects rather than going to the N_Attribute_Definition_Clause
	nodes (may facilitate elimination of those clauses at some point).
	(Inherit_Nonoverridable_Aspects): New procedure to traverse the
	aspects of a derived type's parent type and create inherited versions
	of the parent type's nonoverridable aspects, identifying the appropriate
	subprograms for each such inherited aspect.
	(Inherit_Nonoverridable_Aspect): New procedure nested in
	Inherit_Nonoverridable_Aspects to inherit individual nonoverridable
	aspects. Identifies the corresponding subprogram(s) associated with
	an inherited nonoverridable aspect. In the case of indexing aspects,
	new eligible indexing functions of the type are also identified here,
	and the entities of all of the identified subprograms are appended to
	the aspect's Aspect_Subprograms Elist. Add a "???" comment about this.
	* sinfo.ads: Add documentation for the new Aspect_Subprograms field.
