+
+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>

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

+	(Set_Heterogeneous_Finalize_Address): Explain the reason for the
+	synchronization code.
+	* s-finmas.ads (Set_Heterogeneous_Finalize_Address): Add comment

+	expression of an access-to-object type), return the new value for the
+	saooaaat's associated Extra_Accessibility object.

+	(Init_Size): Add assertion that we are not trashing the

+	(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

+
+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

+
+2011-08-03  Bob Duff  <duff@adacore.com>
+
+	* sem_prag.adb (Get_Base_Subprogram): Do not follow Alias for instances

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