	when analyzing the rewritten result.
	(Expand_Simple_Function_Return): ...here.  Rename local variable.
	Call Apply_CW_Accessibility_Check to apply the check prescribed by
	AI95-344, but do not do it for the simple return statement generated
	by the expansion of an extended return statement.  Apply the check
	prescribed by AI05-0073 to all functions returning anonymous access
	type designating a specific tagged type, but not if the expression
	was null or tag checks are suppressed for the type, and use Not In
	operator rather than comparing the tags explicitly.

	Ada.Strings.Text_Output.Buffers.
	* sem_attr.adb (Check_Image_Type): Enable the Ada 2020 case.

	No_Tasking is globally set.
	* exp_ch9.ads (Build_Master_Declaration): New subprogram.
	* exp_ch9.adb (Build_Activation_Chain_Entity): No action
	performed when restriction No_Tasking is globally set.

2020-06-15  Arnaud Charlet  <charlet@adacore.com>

	* sem_attr.adb (Eval_Attribute): Protect against previous
	errors.
	* sem_ch13.adb (Analyze_Aspect_Default_Value): Remove redundant

2020-06-15  Gary Dismukes  <dismukes@adacore.com>

	* exp_ch6.adb (Add_Call_By_Copy_Code): In the case of a view
	conversion passed to a scalar out-mode parameter where the
	formal has Default_Value set, declare the copy temp with the
	base type of the formal's subtype and initialize the copy temp
	with the actual's value.

2020-06-15  Justin Squirek  <squirek@adacore.com>

	* exp_ch4.adb (Expand_N_Case_Expression): Set default value for
	Target to silence potential warnings.
	(Expand_N_If_Expression): Add calculation to check when the if

	* exp_ch6.adb (Expand_Branch): Generate an assignment to the
	level temporary for a given branch.
	(Expand_Call_Helper): Add expansion to allow for creating a

	trigger proper static accessiblity failiures when the target
	type is an anonymous access.

2020-06-15  Piotr Trojanek  <trojanek@adacore.com>

	* exp_ch6.adb (Expand_Call_Helper): Replace repeated Ekind with
	Ekind_In.

2020-06-15  Piotr Trojanek  <trojanek@adacore.com>

	* exp_ch6.adb, sem_util.adb: Remove excessive parents,
	especially since they don't make the code any easier to read.

2020-06-15  Piotr Trojanek  <trojanek@adacore.com>

	* aspects.ads (Aspect_Id): Add Aspect_Relaxed_Initialization.
	(Implementation_Defined_Aspect): Add new aspect.
	(Aspect_Argument): Add new aspect with Optional_Expression
	argument.
	(Is_Representation_Aspect): Add new aspect as a
	non-representation one.

	query; reuses existing code for querying abstract state options.
	* exp_attr.adb (Expand_N_Attribute_Reference): For now ignore
	attribute 'Initialized.
	* sem_attr.adb (Analyze_Attribute_Old_Result): Allow attribute
	'Result to be used in the aspect Relaxed_Initialization
	expression.
	(Analyze_Attribute): Analyze attribute 'Initialized; based on
	existing code for attribute 'Valid_Scalars.

	routine.
	(Analyze_Aspect_Specifications): Analyze new aspect in a
	dedicated routine.
	(Check_Aspect_At_Freeze_Point): Do not expect new aspect.

2020-06-15  Bob Duff  <duff@adacore.com>

	* exp_put_image.adb, libgnat/s-putima.adb, libgnat/s-putima.ads,
	rtsfind.ads: Enable Put_Image if Is_Access_Subprogram_Type (Typ).
	Remove comment saying it's disabled in that case.  Rename
	Put_Image_Access_Prot to be Put_Image_Access_Prot_Subp to
	clarify that we're talking about access-to-subprogram, not
	access-to-protected-object.

2020-06-15  Bob Duff  <duff@adacore.com>

	* sem_attr.adb (Check_Image_Type): New procedure for checking
	the type, depending on language version. Disable the Ada 2020
	support until the corresponding expander work is done.
	(Analyze_Image_Attribute): Call Check_Image_Type.  Rearrange the
	code to be simplier and more logical.  When P_Type is modified,
	modify P_Base_Type accordingly.
	* sem_util.adb (Is_Object_Image): Do not return False if the
	prefix is a type. X'Image should be considered an image of an
	object iff X is an object (albeit illegal pre-2020 if
	nonscalar).

2020-06-15  Bob Duff  <duff@adacore.com>

	* libgnat/s-putima.ads, libgnat/s-putima.adb
	(Put_Image_Access_Subp, Put_Image_Access_Prot): New procedures
	for printing access-to-subprogram objects.  Remove an explicit
	" ", because Put_Image includes the annoying leading blank.
	* rtsfind.ads: Add new procedures in s-putima.
	* exp_put_image.adb: Call new procedures as appropriate.

2020-06-15  Bob Duff  <duff@adacore.com>

	* exp_imgv.adb (Expand_Image_Attribute): Allow private types.
	Put_Image generates Image for numeric types, and private types
	whose full type is numeric. This requires the Conversion_OK flag
	for integer and floating-point types. For fixed point, we need
	the extra conversion.
	* exp_put_image.adb (Build_Elementary_Put_Image_Call): Remove
	special handling of real types.
	(Enable_Put_Image): Enable for reals.

2020-06-15  Bob Duff  <duff@adacore.com>

	* exp_attr.adb (Put_Image): Use underlying type for strings.
	Remove unchecked union processing.
	* exp_put_image.adb (Tagged_Put_Image_Enabled): Use -gnatd_z to
	enable default Put_Image for tagged types.  This allows testing
	that feature.
	(Build_String_Put_Image_Call): Set Conversion_OK flag.
	(Make_Component_List_Attributes): Remove unchecked union
	processing.
	(Enable_Put_Image): Disable for unchecked unions.  Enable for
	nonscalar types (which were mistakenly disabled in earlier
	changes).
	* debug.adb: Document -gnatd_z switch.
	* libgnat/s-putima.adb (Put_Image_String, Put_Image_Wide_String,
	Put_Image_Wide_Wide_String): Double double-quote characters.
	Forget about special handling of control characters for now --
	that's rare enough to not be a priority, and it's not clear what
	the right thing to do is anyway.
	* namet.adb: Minor: Improve debugger-friendliness.
	* sinfo.ads: Minor: Add "???" comment.

2020-06-15  Piotr Trojanek  <trojanek@adacore.com>

	* sem_util.ads, sem_util.adb (Is_Renaming_Declaration): Remove.

2020-06-15  Ed Schonberg  <schonberg@adacore.com>

	* freeze.adb (Freeze_Expression): When traversing the tree
	looking for the proper insertion point for the freeze node of an
	entity that is declared in an outer scope, set the candidate
	subprogram body node properly.  Previous code has an off-by-one
	error.

2020-06-15  Eric Botcazou  <ebotcazou@adacore.com>

	* exp_attr.adb (Expand_N_Attribute_Reference) <Has_Same_Storage>:
	Do not do superfluous work.  Add the condition (X'Size /= 0) on
	both paths and turn binary AND into short-circuit AND THEN.

2020-06-15  Steve Baird  <baird@adacore.com>

	* sem_attr.adb (Analyze_Attribute): In the Loop_Entry case,
	replace a call to Statically_Denotes_Object with a call to
	Statically_Names_Object and clean up the preceding comment.

2020-06-15  Eric Botcazou  <ebotcazou@adacore.com>

	* sem_res.adb (Resolve_Set_Membership): Remove local variable.
	In the non-overloaded case, call Intersect_Types on the left
	operand and the first alternative to get the resolution type.
	But test the subtype of the left operand to give the warning.

2020-06-12  Steve Baird  <baird@adacore.com>

	* sem_res.adb (Valid_Conversion): The simpler cases of
	violations of the aforementioned 8.6 rule are already handled
	correctly. These include cases where the operand of the type
	conversion is an access parameter or a stand-alone object of an
	anonymous access type. Add code to detect violations where the
	operand of the type conversion is an access discriminant whose
	accessibility level is tied to one of the other simpler cases.
	This is implemented in a new function,
	Valid_Conversion.Is_Discrim_Of_Bad_Access_Conversion_Argument,
	which is called in place of the previous test.

2020-06-12  Bob Duff  <duff@adacore.com>

	* exp_attr.adb (Put_Image): Remove assertion. This assertion is
	False in mixed-Ada-version programs.
	* exp_put_image.adb (Tagged_Put_Image_Enabled): New flag to make
	it easy to experiment with Put_Image on tagged types. False in
	this version.
	(Enable_Put_Image): Enable in pre-2020.  Workarounds: Disable
	for tagged types if Tagged_Put_Image_Enabled is False. Disable
	for access-to-subprogram types.  Disable if errors have been
	detected, or Sink is unavailable.
	(Preload_Sink): Move all conditionals here, from Sem_Ch10, so
	they can be nearby related code in Enable_Put_Image.  Load Sink
	only if we have seen a tagged type.  This removes the dilemma
	about calling Preload_Sink when compiling the compiler, which
	caused unwanted dependences.
	* exp_put_image.ads (Preload_Sink): New formal Compilation_Unit,
	needed to move all conditionals here, from Sem_Ch10.
	* libgnat/a-stouut.adb (Put_UTF_8): Make this suitable for
	inlining, so we don't get warnings about inlining in some tests.
	And so it can be inlined!
	* opt.ads (Tagged_Seen): New flag (see Preload_Sink).
	* scng.adb (Scan): Set new Tagged_Seen flag.
	* sem_ch10.adb (Analyze_Compilation_Unit): Move conditionals and
	comments regarding Preload_Sink into Preload_Sink.

2020-06-12  Arnaud Charlet  <charlet@adacore.com>

	* sem_res.adb (Resolve_Actuals): Check for AI12-0074.

2020-06-12  Olivier Hainque  <hainque@adacore.com>

	* libgnat/s-secsta.ads (Memory_Alignment): New constant, memory
	alignment for chunks and allocated blocks. Initialize to
	Standard'Maximum_Alignment * 2.
	(Chunk_Memory): Use it.
	* libgnat/s-secsta.adb (Round_Up): Likewise.

2020-06-12  Piotr Trojanek  <trojanek@adacore.com>

	* par-prag.adb: Fix ordering.
	* snames.ads-tmpl (Name_Test_Case, Pragma_Test_Case): Likewise.
	* sem_prag.adb (Sig_Flags): Likewise.

2020-06-12  Arnaud Charlet  <charlet@adacore.com>

	* sem_res.adb (Resolve_Entity_Name): Fix handling of expressions
	containing array attributes wrt Ada 83 detection.

2020-06-12  Steve Baird  <baird@adacore.com>

	* sem_util.ads, sem_util.adb: Define 3 new Boolean-valued
	functions - Statically_Denotes_Entity,
	Statically_Denotes_Object, and Statically_Names_Object. The
	first two were taken from sem_attr.adb. The term "statically
	names" is defined in the Ada RM and the new function
	Statically_Names_Object is intended to reflect that definition,
	or more precisely, as described in a comment in the code, to
	reflect the expected future definition of that term.
	* sem_attr.adb: Delete functions Statically_Denotes_Object and
	Statically_Denotes_Entity; these two functions have been moved
	to package Sem_Util. Replace call to Statically_Denotes_Object
	with a call to Statically_Names_Object as per AI12-0217 (a
	binding interpretation, so no Ada_Version check).
	* exp_ch9.adb (Expand_Entry_Barrier.Is_Simple_Barrier): Change
	name of function (it was previously Is_Simple_Barrier_Name)
	because the function should return True in the case of a static
	expression; implement this requirement.  Change function to
	include a call to Statically_Names_Object so that, for Ada_2020
	and later, it will return True for appropriate subcomponent
	names.
	(Expand_Entry_Barrier.Is_Pure_Barrier): Handle
	N_Indexed_Component and N_Selected_Component cases by calling
	Statically_Names_Object.
	(Expand_Entry_Barrier): Reorganize to treat Simple_Barriers and
	Pure_Barriers more uniformly.  Prevent cascaded errors.

2020-06-12  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch12.adb (Find_Matching_Actual): Add guard on search loops
	to detect a compilation error when using a compiler built
	without assertions.
	(Instantiate_Formal_Subprogram): Create a new subprogram name
	for the actual only if formal has contract aspects and expansion
	is enabled.

2020-06-12  Eric Botcazou  <ebotcazou@adacore.com>

	* exp_aggr.adb: Add with and use clauses for Sem_Mech.
	(Get_Base_Object): New function to get the base object of a node.
	(In_Place_Assign_OK): Add Target_Object parameter.  Deal with a
	qualified expression on entry.  Remove short-circuit for array
	aggregates with a single "others" choice.  Do not look into the
	components of the aggregate if the parent is an allocator.
	(Check_Component): Add T_OK parameter and rewrite.
	(Safe_Component): Invoke Check_Component with T_OK set to False.
	(Convert_To_Assignments): Try to use an in-place assignment for
	any target; for that, call Get_Base_Object on the target and pass
	the result to In_Place_Assign_OK.
	(Expand_Array_Aggregate): Use Parent_Kind and Parent_Node more
	consistently.  For an assignment, call Get_Base_Object on the
	target and pass the result to In_Place_Assign_OK.

2020-06-12  Dmitriy Anisimkov  <anisimko@adacore.com>

	* socket.c (__gnat_minus_500ms): Use GetVersionEx to detect
	Windows Server version.
	* libgnat/g-sothco.ads (Minus_500ms_Windows_Timeout): Remade to
	Boolean constant.
	* libgnat/g-socket.adb (Set_Socket_Option): Use
	Minus_500ms_Windows_Timeout constant instead of function call.

2020-06-12  Arnaud Charlet  <charlet@adacore.com>

	* libgnat/a-coinho.ads, libgnat/a-coinho.adb,
	libgnat/a-coinho__shared.ads, libgnat/a-coinho__shared.adb
	(Swap): New procedure.

2020-06-12  Arnaud Charlet  <charlet@adacore.com>

	* exp_ch6.adb (Expand_N_Subprogram_Declaration): Do nothing for
	a subprogram declared in a protected body.
	* exp_ch9.ads, exp_ch9.adb
	(Build_Private_Protected_Declaration): Moved to sem_ch6.adb.
	(Expand_N_Protected_Body): Do nothing for a subprogram declared
	in a protected body.
	* sem_ch6.adb (Build_Internal_Protected_Declaration): Moved from
	exp_ch9.adb and renamed and fixed to ensure in particular that
	such subprograms have convention Intrinsic and have no protected
	version.
	(Analyze_Subprogram_Body_Helper): Call
	Build_Internal_Protected_Declaration.
	(Move_Pragmas): Moved up and merged with the more general
	version from Build_Private_Protected_Declaration. We only want
	to copy selected pragmas, most pragmas are not suitable for a
	copy on the spec.

2020-06-12  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch6.adb (Check_Overriding_Indicatior): Reject an
	overriding indicator on a subprogram declared within a protected
	body.

2020-06-12  Piotr Trojanek  <trojanek@adacore.com>

	* contracts.adb, einfo.adb, sem_ch4.adb, sem_ch6.adb,

	13.1(9.2/5) for representation aspects.

2020-06-12  Bob Duff  <duff@adacore.com>

	* exp_put_image.ads, exp_put_image.adb (Preload_Sink): Procedure
	for preloading type Sink.  This has the side effect of loading
	various dependents, including Ada.Strings.UTF_Encoding.
	(Enable_Put_Image): Disable Put_Image in pre-2020 versions of
	Ada.  This limitation can probably be lifted later.  Enable for
	tagged types except in predefined units.  Disable for CPP types;

	more than a call to Check_Type_Or_Object_External_Properties.
	* contracts.ads: Update comment for Add_Contract_To_Item because
	types can have contracts.  Follow (questionable) precedent and
	declare new routine Analyze_Type_Contract as visible (following
	example of Analyze_Object_Contract), despite the fact that it is
	never called from outside of the package where it is declared.
	* einfo.adb (Contract, Set_Contract): Id argument can be a type;
	support this case.
	(Write_Field34_Name): Field name is "contract" for a type.
	* einfo.ads: Update comment describing Contract attribute.
	* sem_ch3.adb (Build_Derived_Numeric_Type): Is_Volatile should
	return same answer for all subtypes of a given type. Thus, when

	Check_Volatility_Compatibility.
	* sem_util.adb (Async_Readers_Enabled, Async_Writers_Enabled,
	Effective_Reads, Effective_Writes): Initial implementation of
	new functions for querying aspect values.
	(Check_Volatility_Compatibility): New procedure intended for use
	in checking all SPARK legality rules of the form "<> shall be
	compatible with respect to volatility with <>".
	(Has_Enabled_Property): Update comment because Item_Id can be a
	type.  Change name of nested Variable_Has_Enabled_Property
	function to Type_Or_Variable_Has_Enabled_Property; add a
	parameter to that function because recursion may be needed,
	e.g., in the case of a derived typ).  Cope with the case where

	Put_Image_Unknown.
	* libgnat/s-putima.ads, libgnat/s-putima.adb
	(Put_Image_Unknown): Add Type_Name parameter.  Remove
	overly-detailed documentation of what it does; better to leave

	block, now a separate procedure; the only change is that now

	did before); extend a ??? comment about how this routine is
	different from the Build_Subtype
	(Resolve_Record_Aggregate): Create a constrained itype not just
	for the outermost record aggregate, but for its inner record
	aggregates as well.

	* sem_ch13.adb (Analyze_Aspect_Specifications): Do not set the
	Has_Predicates flag when the Predicate_Failure aspect is seen.
	It is legal (but pointless) to use this aspect without a
	predicate.  If we set the flag, we generate a half-baked

2020-06-11  Bob Duff  <duff@adacore.com>

	* exp_put_image.adb (Build_Record_Put_Image_Procedure): Remove
	special processing of protected types, because those are handled

	Ravenscar variant (i.e., not Jorvik).

2020-06-08  Arnaud Charlet  <charlet@adacore.com>

	aggregate that is the initial value of the constant
	Profile_Info.
	* targparm.adb (Get_Target_Parameters): Handle "pragma Profile
	(Jorvik);" similarly to "pragma Profile (Ravenscar);".
	* snames.ads-tmpl: Declare Name_Jorvik Name_Id. Unlike
	Ravenscar, Jorvik is not a pragma name and has no corresponding
	element in the Pragma_Id enumeration type; this means that its
	declaration must not occur between those of First_Pragma_Name
	and Last_Pragma_Name.
	* sem_prag.adb (Analyze_Pragma): Add call to
	Set_Ravenscar_Profile for Jorvik, similar to the existing calls
	for Ravenscar and the GNAT Ravenscar variants.

2020-06-08  Steve Baird  <baird@adacore.com>

	* sem_ch13.ads: Export new function
	All_Membership_Choices_Static.
	* sem_ch13.adb: Implement new function
	All_Membership_Choices_Static.  This involves moving the
	functions Is_Static_Choice and All_Membership_Choices_Static,
	which were previously declared within the function
	Is_Predicate_Static, out to library level so that they can be
	called by the new function. The already-exisiting code in
	Is_Predicate_Static which became the body of
	All_Membership_Choices_Static is replaced with a call to the new
	function in order to avoid duplication.
	* exp_ch9.adb (Is_Pure_Barrier): Several changes needed to
	implement rules of AI12-0290 and RM D.7's definition of
	"pure-barrier-eligible". These changes include adding a call to
	the new function Sem_13.All_Membership_Choices_Static, as per
	the "see 4.9" in RM D.7(1.6/5).

2020-06-08  Richard Kenner  <kenner@adacore.com>

	* checks.adb (Apply_Predicate_Check): Refine test for being in a
	subprogram body to account for no Corresponding_Body case,
	avoiding blowups arising due to other changes here.
	* exp_ch4.adb (Expand_N_Qualified_Expression): Apply predicate
	checks, if any, after constraint checks are applied.
	* sem_eval.ads (Check_Expression_Against_Static_Predicate): Add
	Check_Failure_Is_Error formal for conditionalizing warning vs.
	error messages.
	* sem_eval.adb (Check_Expression_Against_Static_Predicate):
	Issue an error message rather than a warning when the new
	Check_Failure_Is_Error formal is True. In the nonstatic or
	Dynamic_Predicate case where the predicate is known to fail,
	emit the check to ensure that folded cases get checks applied.
	* sem_res.adb (Resolve_Qualified_Expression): Call
	Check_Expression_Against_Static_Predicate, passing True for
	Check_Failure_Is_Error, to ensure we reject static predicate
	violations. Remove code that was conditionally calling
	Apply_Predicate_Check, which is no longer needed, and that check
	procedure shouldn't be called from a resolution routine in any
	case. Also remove associated comment about preventing infinite
	recursion and consistency with Resolve_Type_Conversion, since
	that handling was already similarly removed from
	Resolve_Type_Convesion at some point.
	(Resolve_Type_Conversion): Add passing of True for
	Check_Failure_Is_Error parameter on call to

2020-06-08  Philippe Gil  <gil@adacore.com>

	* doc/gnat_ugn/the_gnat_compilation_model.rst: in "Handling
	Files with Multiple Units" part documents gnatname use for

2020-06-08  Javier Miranda  <miranda@adacore.com>

	* exp_aggr.adb (Safe_Component): Remove code that considers as
	unsafe components that are aggregates; such removal allows the
	frontend to proceed and evaluate if they are safe by means of
	invoking Safe_Aggregate.

2020-06-08  Piotr Trojanek  <trojanek@adacore.com>

	* exp_spark.adb (Expand_SPARK_N_Attribute_Reference): Apply
	standard expansion to attributes First and Last.

2020-06-08  Piotr Trojanek  <trojanek@adacore.com>

2020-06-08  Arnaud Charlet  <charlet@adacore.com>

	only checking renamings coming from sources.
	* sem_util.adb (Is_Object_Reference): Update for AI12-0226 and
	add more regular handling of 'Priority. Remove special cases no
	longer needed now that we are only checking renamings coming
	from sources.

2020-06-08  Claire Dross  <dross@adacore.com>

	* libgnat/a-cofove.adb (Insert_Space): The computation of Index
	generates a spurious compiler warning about a value not being in
	range for a statically dead branch.  Silence it using pragma
	Warnings.

2020-06-08  Bob Duff  <duff@adacore.com>

	* bindo-graphs.adb (function Add_Edge): Rename
	Add_Edge_With_Return to Add_Edge; we can tell it returns because
	it's a function, and overloading seems appropriate in this case.
	If Activates_Task=True, and we're not going to add a new edge
	because an existing Pred-->Succ edge already exists, then set
	Activates_Task to True on the preexisting edge.  This ensures
	that the message:
	info: use pragma Restrictions (No_Entry_Calls_In_Elaboration_Code)
	appears when appropriate, no matter in what order the edges
	happened to be processed.
	(procedure Add_Edge): Remove redundant assertions.
	(Activates_Task): Other kinds of edges can have
	Activates_Task=True.  For example, if we had a With_Edge and
	then an Invocation_Edge with Activates_Task=True, then the
	With_Edge has Activates_Task set to True.
	(Add_Edge_Kind_Check): New procedure to prevent other bugs of
	this nature. For example, if we were to sometimes call Add_Edge
	for a Spec_Before_Body_Edge followed by Add_Edge for a
	With_Edge, and sometimes in the other order, that would cause a
	similar bug to what we're fixing here.
	(Set_Is_Recorded_Edge): Val parameter is not used. Get rid of
	it.
	(Set_Activates_Task): New procedure to set the Activates_Task flag.
	* bindo-graphs.ads (Library_Graph_Edge_Kind): Reorder the
	enumeration literals to facilitate Add_Edge_Kind_Check.
	* ali.adb (Known_ALI_Lines): The comment about "still available"
	was wrong. Fix that by erasing the comment, and encoding the
	relevant information in real code. Take advantage of Ada's full
	coverage rules by removing "others =>".  Also DRY.

2020-06-08  Ed Schonberg  <schonberg@adacore.com>

	* par-ch12.adb (P_Formal_Derived_Type_Definition): Handle
	properly formal derived types that include aspect

	* sem_ch13.adb (Has_Generic_Parent): Return true if the type
	itself is a generic formal.

2020-06-05  Ed Schonberg  <schonberg@adacore.com>

	(Process_Range_Expr_In_Decl): Change default to No_List for
	the Check_List parameter.
	* sem_ch3.adb: ...here.
	(Process_Range_Expr_In_Decl): Likewise.  When the insertion
	node is a declaration, only insert on the list if is present
	when the declaration involves discriminants, and only insert
	on the node when there is no list otherwise.

2020-06-05  Piotr Trojanek  <trojanek@adacore.com>

	* sem_aggr.adb (Resolve_Record_Aggregate): Create the

	Exp_Value.

2020-06-05  Bob Duff  <duff@adacore.com>

	* rtsfind.adb, rtsfind.ads: Move subtypes of RTU_Id into package
	body, because they are not needed by clients. Change "Child_" to
	"Descendant", because grandchildren and great grandchildren are
	involved.  Replace all the repetitive comments with a single
	concise one.  Change the parent subtypes to be more consistent;
	use the most specific parent.

	* sem_ch9.adb, (Analyze_Task_Body): After analying the task
	body, indicate that all local variables have no delayed aspects.
	This prevents improper later calls to
	Check_Aspect_At_End_Of_Declarations, that would happen when the
	constructed task_procedure body (generated during expansion) is
	analyzed. The legality of aspect specifications that may appear
	on local declarations has already been established, and it is in
	general not possible to recheck them properly during expansion,
	when visibility may not be fully established.
