	* einfo.ads (Extra_Accessibility): Update associated comment to use

	* sem_util.adb, exp_ch6.adb: Minor reformatting and code reorganization.

2011-09-06  Steve Baird  <baird@adacore.com>

	* einfo.ads (Extra_Accessibility_Of_Result): New function; in the
	(Ada2012) cases described in AI05-0234 where the accessibility
	level of a function result is "determined by the point of
	call", an implicit parameter representing that accessibility
	level is passed in. Extra_Accessibilty_Of_Result yields this
	additional formal parameter. Extra_Accessibility_Of_Result
	is analogous to the existing Extra_Accessibility
	function used in the implementation of access parameters.
	(Set_Extra_Accessibility_Of_Result): New procedure; sets
	Extra_Accessibility_Of_Result attribute.
	* einfo.adb (Extra_Accessibility_Of_Result): New function.
	(Set_Extra_Accessibility_Of_Result): New procedure.
	(Write_Field19_Name): Display Extra_Accessibilty_Of_Result attribute.
	* sem_util.adb (Dynamic_Accessibility_Level): Set Etype of
	an accessibility level literal to Natural; introduce a nested
	function, Make_Level_Literal, to do this.
	* exp_ch6.ads (Needs_Result_Accessibility_Level): New function;
	determines whether a given function (or access-to-function
	type) needs to have an implicitly-declared accessibility-level
	parameter added to its profile.
	(Add_Extra_Actual_To_Call): Export an existing procedure which was
	previously declared in the body of Exp_Ch6.
	* exp_ch6.adb (Add_Extra_Actual_To_Call): Export declaration by moving
	it to exp_ch6.ads.
	(Has_Unconstrained_Access_Discriminants): New Function; a
	predicate on subtype entities which returns True if the given
	subtype is unconstrained and has one or more access discriminants.
	(Expand_Call): When expanding a call to a function which takes an
	Extra_Accessibility_Of_Result parameter, pass in the appropriate
	actual parameter value. In the case of a function call which is
	used to initialize an allocator, this may not be possible because
	the Etype of the allocator may not have been set yet. In this
	case, we defer passing in the parameter and handle it later in
	Expand_Allocator_Expression.
	(Expand_Simple_Function_Return): When returning from a function which
	returns an unconstrained subtype having at least one access
	discriminant, generate the accessibility check needed to ensure that
	the function result will not outlive any objects designated by its
	discriminants.
	(Needs_Result_Accessibility_Level): New function; see exp_ch6.ads
	description.
	* exp_ch4.adb (Expand_Allocator_Expression): When a function call
	is used to initialize an allocator, we may need to pass in "the
	accessibility level determined by the point of call" (AI05-0234)
	to the function. Expand_Call, where such actual parameters are
	usually generated, is too early in this case because the Etype of
	the allocator (which is used in determining the level to be passed
	in) may not have been set yet when Expand_Call executes. Instead,
	we generate code to pass in the appropriate actual parameter
	in Expand_Allocator_Expression.
	* sem_ch6.adb (Create_Extra_Formals): Create
	the new Extra_Accessibility_Of_Result formal if
	Needs_Result_Accessibility_Level returns True. This includes the
	introduction of a nested procedure, Check_Against_Result_Level.

2011-09-06  Arnaud Charlet  <charlet@adacore.com>

	* gcc-interface/Makefile.in (X86_TARGET_PAIRS): Remove duplicate
	declaration.

2011-09-05  Hristian Kirtchev  <kirtchev@adacore.com>

	* s-finmas.adb (Set_Finalize_Address): Explain the reason

	s-stposu.Allocate_Any_Controlled to this routine since the check
	needs to be protected too.
	(Set_Heterogeneous_Finalize_Address): Explain the reason for the
	synchronization code.
	* s-finmas.ads (Set_Heterogeneous_Finalize_Address): Add comment
	explaining the context in which this routine is used.
	* s-stposu.adb (Allocate_Any_Controlled): Move the test for null

	* s-finmas.adb (Set_Finalize_Address (Address,

2011-08-30  Steve Baird  <baird@adacore.com>

	* sem_util.ads (Deepest_Type_Access_Level): New function; for the type
	of a saooaaat (i.e, a stand-alone object of an anonymous access type),
	returns the (static) accessibility level of the object. Otherwise, the
	same as Type_Access_Level.
	(Dynamic_Accessibility_Level): New function; given an expression which
	could occur as the rhs of an assignment to a saooaaat (i.e., an
	expression of an access-to-object type), return the new value for the
	saooaaat's associated Extra_Accessibility object.
	(Effective_Extra_Accessibility): New function; same as
	Einfo.Extra_Accessibility except that object renames are looked through.
	* sem_util.adb 
	(Deepest_Type_Access_Level): New function; see sem_util.ads description.
	(Dynamic_Accessibility_Level): New function; see sem_util.ads
	description.
	(Effective_Extra_Accessibility): New function; see sem_util.ads
	description.
	* einfo.ads (Is_Local_Anonymous_Access): Update comments.
	(Extra_Accessibility): Update comments.
	(Init_Object_Size_Align): New procedure; same as Init_Size_Align
	except RM_Size field (which is only for types) is unaffected.
	* einfo.adb
	(Extra_Accessibility): Expand domain to allow objects, not just formals.
	(Set_Extra_Accessibility): Expand domain to allow objects, not just
	formals.
	(Init_Size): Add assertion that we are not trashing the
	Extra_Accessibility attribute of an object.
	(Init_Size_Align): Add assertion that we are not trashing the
	Extra_Accessibility attribute of an object.
	(Init_Object_Size_Align): New procedure; see einfo.ads description.
	* sem_ch3.adb (Find_Type_Of_Object): Set Is_Local_Anonymous_Access
	differently for the type of a (non-library-level) saooaaat depending
	whether Ada_Version < Ada_2012. This is the only point where Ada_Version
	is queried in this set of changes - everything else (in particular,
	setting of the Extra_Accessibility attribute in exp_ch3.adb) is
	driven off of the setting of the Is_Local_Anonymous_Access attribute.
	The special treatment of library-level saooaaats is an optimization,
	not required for correctnesss. This is based on the observation that the
	Ada2012 rules (static and dynamic) for saooaaats turn out to be
	equivalent to the Ada2005 rules in the case of a library-level saooaaat.
	* exp_ch3.adb
	(Expand_N_Object_Declaration): If Is_Local_Anonymous_Access is
	false for the type of a saooaaat, declare and initialize its
	accessibility level object and set the Extra_Accessibility attribute
	of the saooaaat to refer to this object.
	* checks.adb (Apply_Accessibility_Check): Add Ada 2012 saooaaat support.
	* exp_ch4.adb (Expand_N_In): Replace some Extra_Accessibility calls with
	calls to Effective_Extra_Accessibility in order to support
	renames of saooaaats.
	(Expand_N_Type_Conversion): Add new local function,
	Has_Extra_Accessibility, and call it when determining whether an
	accessibility check is needed.
	It returns True iff Present (Effective_Extra_Accessibility (Id)) would
	evaluate to True (without raising an exception).
	* exp_ch5.adb
	(Expand_N_Assignment_Statement): When assigning to an Ada2012
	saooaaat, update its associated Extra_Accessibility object (if
	it has one). This includes an accessibility check.
	* exp_ch6.adb (Add_Call_By_Copy_Code): When parameter copy-back updates
	a saooaaat, update its Extra_Accessibility object too (if it
	has one).
	(Expand_Call): Replace a couple of calls to Type_Access_Level
	with calls to Dynamic_Access_Level to handle cases where
	passing a literal (any literal) is incorrect.
	* sem_attr.adb (Resolve_Attribute): Handle the static accessibility
	checks associated with "Saooaat := Some_Object'Access;"; this must
	be rejected if Some_Object is declared in a more nested scope
	than Saooaat.
	* sem_ch5.adb (Analyze_Assignment): Force accessibility checking for an
	assignment to a saooaaat even if Is_Local_Anonymous_Access
	returns False for its type (indicating a 2012-style saooaaat).
	* sem_ch8.adb
	(Analyze_Object_Renaming): Replace a call to Init_Size_Align
	(which is only appropriate for objects, not types) with a call
	of Init_Object_Size_Align in order to avoid trashing the
	Extra_Accessibility attribute of a rename (the two attributes
	share storage).
	* sem_res.adb
	(Valid_Conversion) Replace six calls to Type_Access_Level with
	calls to Deepest_Type_Access_Level. This is a bit tricky. For an
	Ada2012 non-library-level saooaaat, the former returns library level
	while the latter returns the (static) accessibility level of the
	saooaaat. A type conversion to the anonymous type of a saooaaat
	can only occur as part of an assignment to the saooaaat, so we
	know that such a conversion must be in a lhs context, so Deepest
	yields the result that we need. If such a conversion could occur,
	say, as the operand of an equality operator, then this might not
	be right. Also add a test so that static accessibilty checks are
	performed for converting to a saooaaat's type even if
	Is_Local_Anonymous_Access yields False for the type.

2011-08-30  Javier Miranda  <miranda@adacore.com>

	* sem_disp.adb (Check_Dispatching_Operation): Complete condition that
	controls generation of a warning associated with late declaration of
	dispatching functions. Required to avoid generating spurious
	warnings.

2011-08-30  Gary Dismukes  <dismukes@adacore.com>

	* sem_ch6.adb (Check_Return_Subtype_Indication): Issue error if the
	return object has an anonymous access type and the function's type is
	a named access type.
	* sem_ch8.adb (Analyze_Object_Renaming): Suppress error about renaming
	conversions on implicit conversions, since such conversions can occur
	for anonymous access cases due to expansion. Issue error for attempt
	to rename an anonymous expression as an object of a named access type.
	* sem_res.ads (Valid_Conversion): Add defaulted parameter Report_Errs,
	to indicate whether this function should report errors on invalid
	conversions.
	* sem_res.adb (Resolve): For Ada 2012, in the case where the type of
	the expression is of an anonymous access type and the expected type is
	a named general access type, rewrite the expression as a type
	conversion, unless this is an expression of a membership test.
	(Valid_Conversion.Error_Msg_N): New procedure that conditions the
	calling of Error_Msg_N on new formal Report_Errs.
	(Valid_Conversion.Error_Msg_NE): New procedure that conditions the
	calling of Error_Msg_NE on new formal Report_Errs.
	(Valid_Conversion): Move declaration of this function to the package
	spec, to allow calls from membership test processing. For Ada 2012,
	enforce legality restrictions on implicit conversions of anonymous
	access values to general access types, disallowing such conversions in
	cases where the expression has a dynamic accessibility level (access
	parameters, stand-alone anonymous access objects, or a component of a
	dereference of one of the first two cases).
	* sem_type.adb (Covers): For Ada 2012, allow an anonymous access type
	in the context of a named general access expected type.
	* exp_ch4.adb Add with and use of Exp_Ch2.
	(Expand_N_In): Add processing for membership tests applied to
	expressions of an anonymous access type. First, Valid_Conversion is
	called to check whether the test is statically False, and then the
	conversion is expanded to test that the expression's accessibility
	level is no deeper than that of the tested type. In the case of
	anonymous access-to-tagged types, a tagged membership test is applied
	as well.
	(Tagged_Membership): Extend to handle access type cases, applying the
	test to the designated types.
	* exp_ch6.adb (Expand_Call): When creating an extra actual for an
	accessibility level, and the actual is a 'Access applied to a current
	instance, pass the accessibility level of the type of the current
	instance rather than applying Object_Access_Level to the prefix. Add a
	??? comment, since this level isn't quite right either (will eventually
	need to pass an implicit level parameter to init procs).

	* s-taskin.ads: Minor comment fix.

2011-08-30  Ed Schonberg  <schonberg@adacore.com>

	* sem_res.adb (Check_Parameterless_Call): If the node is a selected

	* sem_ch8.adb (Analyze_Object_Renaming): If the renamed object is a
	function call of a limited type, the expansion of the renaming is
	complicated by the presence of various temporaries and subtypes that

	they manipulate the queue. It is also likely that they can be adapted
	for gnatmake, thus sharing more code.
	(Finish_Program, Fail_Program): moved from the gprbuild sources, so
	that we could move the above.

2011-08-03  Emmanuel Briot  <briot@adacore.com>

	where the Condition cannot have side-effects in ALFA
	(Analyze_Membership_Op): do not mark such nodes as not in ALFA
	(Analyze_Type_Conversion): do not always mark such nodes as not in ALFA.

	(Traverse_Declarations_Or_Statements,

	finalization and reclamation. Type Finalization_Collection is
	effectively a wrapper which sits ontop of a storage pool and performs
	all necessary bookkeeping for all the objects it contains. Each
	access-to-controlled or access-to-class-wide type receives a collection
	as part of its expansion. The compiler generates buffer code and
	invokes Allocate / Deallocate to create and destroy allocated
	controlled objects.

	Since tagged types with controlled components no longer carry hidden
	field _controller, the special mechanism to retrieve its location is no

	targets. Set the correct library finalization routine depending on
	whether the library has controlled objects or this is a VM compilation.
	(Gen_Finalize_Library_Ada): New routine. This procedure generates calls
	to library-level finalizers of compiled units in reverse order of

	Generate a with clause for System.Soft_Links when compiling for a VM.
	Remove the code which imports System.Standard_Library.Adafinal as

	(Gen_Output_File_C): Add new local constant Needs_Library_Finalization.
	If the library needs finalization actions, create all the definitions
	of library- level finalizers.
	(Has_Finalizer): New routine. Determines whether at least one compiled
	unit has a library-level finalizer.
	Add type Qualification_Mode.

2011-08-03  Bob Duff  <duff@adacore.com>

	* sem_prag.adb (Resolve_Aggregate): An array aggregate with 'others' is
	always legal on the right-hand side of an assignment statement; there
	is always an applicable index constraint in this case. Therefore, the
	check for Pkind = N_Assignment_Statement is now unconditional -- it
	doesn't depend on whether Is_Constrained (Typ).

2011-08-03  Thomas Quinot  <quinot@adacore.com>

	* exp_ch5.adb (Expand_N_Assignment_Statement): Do not force inlining of
	tagged assignment when discriminant checks are suppressed. This is
	useless and extremely costly in terms of static stack usage.

2011-08-03  Bob Duff  <duff@adacore.com>

	* sem_prag.adb (Get_Base_Subprogram): Do not follow Alias for instances
	of generics, because this leads to the wrong entity in the wrong scope,
	causing (e.g.) pragma Export_Procedure to get an error if the entity is
	an instance.
	(Process_Interface_Name): Follow Alias for instances of generics, to
	correct for the above change.

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

	* exp_ch4.adb (Expand_N_Selected_Component): If the discriminant value
	is an integer literal it is always safe to replace the reference. In
	addition, if the reference appears in the generated code for an object
	declaration it is necessary to copy because otherwise the reference
	might be to the uninitilized value of the discriminant of the object
	itself.

2011-08-03  Pascal Obry  <obry@adacore.com>

	* exp_ch13.adb (Expand_N_Freeze_Entity): cleanup determination of scope
	in which entity is frozen, to handle properly loop variables in
	iterators.

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

	* sem_res.adb (Set_String_Literal_Subtype): if the lower bound of the
	subtype is not static, compute the upper bound using attributes, to
	handle properly index types that are not integer types.

	* sem_util.ads, exp_aggr.adb, exp_ch3.adb: Minor reformatting.

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch3.adb (Analyze_Object_Declaration): if a constant object of an
	unconstrained type with discriminants is initialized with an aggregate,
	use the constrained subtype of the aggregate as the type of the object,
	because it is immutable, and this allows the back-end to generate no
	code for the object declaration.

2011-08-03  Robert Dewar  <dewar@adacore.com>

	* exp_ch4.adb (Optimize_Length_Check): Fix bad handling of case where

	sem_ch6.adb, sem_ch11.adb: Add semantic flag In_Pre_Post_Expression to
	indicate that we are in a precondition or postcondition. This is used in
	Mark_Non_ALFA_Subprogram (renaming of Mark_Non_ALFA_Subprogram_Body) to
	decide whether to flag the spec or body of the current subprogram as
	not in ALFA.

2011-08-02  Fabien Chouteau  <chouteau@adacore.com>

	(Extract_Dispatching_Call): If the type of the dispatching object is an

	to the proper position in the full type's primitives
	list later in Sem_Disp.Check_Operation_From_Incomplete_Type.

	* sem_ch6.adb (Process_Formals): First, remove test for being in a
	private part when determining whether to add a primitive with a

	* sem_ch7.adb (Uninstall_Declarations): When checking the rule of
	RM05-3.10.1(9.3/2), test that a subprogram in the Private_Dependents

	cases where nonprimitives can be in the list (such as subprograms in
	nested packages).
	* sem_disp.adb (Derives_From): Use correct condition for checking that
	a formal's type is derived from the type of the corresponding formal in
	the parent subprogram (the condition was completely wrong). Add
	checking that was missing for controlling result types being derived
	from the result type of the parent operation.
