+ (Dynamic_Accessibility_Level): New function; given an expression which

+ 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

+ (Set_Extra_Accessibility): Expand domain to allow objects, not just

+ (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.
+

+

+ 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).
