object (for this purpose the object should be explicitly marked as
aliased, but being an anonymous type this is not possible).

* sem_ch8.adb (Note_Redundant_Use): Suppress unhelpful warning about
redundant use clauses.
In particular, if the scope of two use clauses overlaps, but one is not
entirely included in the other, we should not warn.  This can happen
with nested packages.
(Analyze_Subprogram_Renaming): Protect the compiler against previously
reported errors. The bug was reported when the compiler was built
with assertions enabled.
(Find_Type): If the node is a 'Class reference and the prefix is a
synchronized type without a corresponding record, return the type
itself.

* sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
abstract interpretations on an operator, remove interpretations that
yield Address or a type derived from it, if one of the operands is an
integer literal.
(Try_Object_Operation.Try_Primitive_Operation,
Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
location when creating the new reference to a primitive or class-wide
operation as a part of rewriting a subprogram call.
(Try_Primitive_Operations): If context requires a function, collect all
interpretations after the first match, because there may be primitive
operations of the same type with the same profile and different return
types. From code reading.
(Try_Primitive_Operation): Use the node kind to choose the proper
operation when a function and a procedure have the same parameter
profile.
(Complete_Object_Operation): If formal is an access parameter and prefix
is an object, rewrite as an Access reference, to match signature of
primitive operation.
(Find_Equality_Type, Find_One_Interp): Handle properly equality given
by an expanded name with prefix Standard, when the operands are of an
anonymous access type.
(Remove_Abstract_Operations): If the operation is abstract because it is
inherited by a user-defined type derived from Address, remove it as
well from the set of candidate interpretations of an overloaded node.
(Analyze_Membership_Op): Membership test not applicable to cpp-class
types.

* sem_ch12.adb (Inline_Instance_Body): Remove erroneous assumption
that Scope_Stack.First = 1.
Properly handle Ada_Version_Explicit and Ada_Version_Config, which
were not always properly handled previously.
(Formal_Entity): Complete rewrite, to handle properly some complex case
with multiple levels of parametrization by formal packages.
(Analyze_Formal_Derived_Type): Propagate Ada 2005 "limited" indicator
to the corresponding derived type declaration for proper semantics.

* sem_prag.adb (Analyze_Pragma): Remove '!' in warning message.
(Check_Component): Enforce restriction on components of
unchecked_unions: a component in a variant cannot contain tasks or
controlled types.
(Unchecked_Union): Allow nested variants and multiple discriminants, to
conform to AI-216.
Add pragma Ada_2005 (synonym for Ada_05)
Properly handle Ada_Version_Explicit and Ada_Version_Config, which
were not always properly handled previously.
Document that pragma Propagate_Exceptions has no effect
(Analyze_Pragma, case Pure): Set new flag Has_Pragma_Pure
(Set_Convention_From_Pragma): Check that if a convention is
specified for a dispatching operation, then it must be
consistent with the existing convention for the operation.
(CPP_Class): Because of the C++ ABI compatibility, the programmer is no
longer required to specify an vtable-ptr component in the record. For
compatibility reasons we leave the support for the previous definition.
(Analyze_Pragma, case No_Return): Allow multiple arguments

* sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Flag a
non-overrideen inherited operation with a controlling result as
illegal only its implicit declaration comes from the derived type
declaration of its result's type.
(Check_Possible_Deferred_Completion): Relocate the object definition
node of the subtype indication of a deferred constant completion rather
than directly analyzing it. The analysis of the generated subtype will
correctly decorate the GNAT tree.
(Record_Type_Declaration): Check whether this is a declaration for a
limited derived record before analyzing components.
(Analyze_Component_Declaration): Diagnose record types  not explicitly
declared limited when a component has a limited type.
(Build_Derived_Record_Type): Code reorganization to check if some of
the inherited subprograms of a tagged type cover interface primitives.
This check was missing in case of a full-type associated with a private
type declaration.
(Constant_Redeclaration): Check that the subtypes of the partial and the
full view of a constrained deferred constant statically match.
(Mentions_T): A reference to the current type in an anonymous access
component declaration  must be an entity name.
(Make_Incomplete_Type_Declaration): If type is tagged, set type of
class_wide type to refer to full type, not to the incomplete one.
(Add_Interface_Tag_Components): Do nothing if RE_Interface_Tag is not
available. Required to give support to the certified run-time.
(Analyze_Component_Declaration): In case of anonymous access components
perform missing checks for AARM 3.9.2(9) and 3.10.2 (12.2).
(Process_Discriminants): For an access discriminant, use the
discriminant specification as the associated_node_for_itype, to
simplify accessibility checks.

* sem_ch10.adb (Check_Redundant_Withs): New procedure in
Analyze_Compilation_Unit.
Detect and warn on redundant with clauses detected in a package spec
and/or body when -gnatwr is used.
(Analyze_Context): Analyze config pragmas before other items
(Install_Context_Items): Don't analyze config pragmas here
(Install_Limited_Withed_Unit): Set limited entity of package in
with_clause so that cross-reference information or warning messages on
unused packages can be properly generated
(Is_Visible_Through_Renamings): Return false if the limited_with_clause
has Error_Posted set. Prevent infinite loops in illegal programs.
(Check_Private_Child_Unit): Move test for a nonprivate with clause down
to the point of the error test requiring the current unit to be private.
This ensures that private with clauses are not exempted from the basic
checking for being a descendant of the same library unit parent as a
withed private descendant unit.
(Check_Private_Limited_Withed_Unit): Revise the checking algorithm to
handle private with clauses properly, as well as to account for cases
where the withed unit is a public descendant of a private ancestor
(in which case the current unit must be a descendant of the private
ancestor's parent). The spec comments were updated accordingly. Also,
the old error message in this subprogram was replaced with error
messages that mirror the errors tested and reported by
Check_Private_Child_Unit.
Parameter and variable names improved for readability.
(Install_Limited_Context_Clauses): Remove test for a withed unit being
private as the precondition for calling
Check_Private_Limited_Withed_Unit since that subprogram has been
revised to test public units as well as private units.

* sem_attr.adb (Analyze_Attribute): In case of 'Class applied to an
abstract interface type call analyze_and_resolve to expand the type
conversion into the corresponding displacement of the
reference to the base of the object.
(Eval_Attribute, case Width): For systems where IEEE extended precision
is supported, the maximum exponent occupies 4 decimal digits.
(Accessibility_Message): Add '\' in 2-line warning message.
(Resolve_Attribute): Likewise.
(case Attribute_Access): Significantly revise checks
for illegal access-to-subprogram Access attributes to properly enforce
the rules of 3.10.2(32/2).
Diagnose use of current instance with an illegal attribute.

        * sem_util.ads, sem_util.adb (Enclosing_Generic_Body): Change formal
        to a Node_Id.
        (Enclosing_Generic_Unit): New function to return a node's innermost
        enclosing generic declaration node.
        (Compile_Time_Constraint_Error): Remove '!' in warning messages.
        (Type_Access_Level): The accessibility level of anonymous acccess types
        associated with discriminants is that of the current instance of the
        type, and that's deeper than the type itself (AARM 3.10.2 (12.3.21)).
        (Compile_Time_Constraint_Error): Handle case of conditional expression.
        (Kill_Current_Values_For_Entity): New function
        (Enter_Name): Change formal type to Entity_Id

* sem_aggr.adb (Resolve_Record_Aggregate): Restructure the code that
handles default-initialized components to keep separate the management
of this feature but also avoid the unrequired resolution and
expansion of components that do not have partially initialized
values.
(Collect_Aggr_Bounds): Add '\' in 2-line warning message.
(Check_Bounds): Likewise.
(Check_Length): Likewise.
