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.

* sem_res.adb (Resolve): For Ada 2012, in the case where the type of

(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

need to pass an implicit level parameter to init procs).
