* sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
of Analyze_Package_Body, to create Itype references for anonymous
access types created in the package declaration, whose designated types
may have only a limited view.
(Analyze_Package_Specification): For the private part of a nested
package, install private_with_clauses of enclosing compilation unit if
we are in its visible part.
(Declare_Inherited_Private_Subprograms): Complete barrier
to ensure that the primitive operation has an alias to some parent
primitive. This is now required because, after the changes done for the
implementation of abstract interfaces, the contents of the list of
primitives has entities whose alias attribute references entities of
such list of primitives.
(Analyze_Package_Specification): Simplify code that handles parent units
of instances and formal packages.
(Uninstall_Declarations): Check the convention consistency among
primitive overriding operations of a tagged record type.

* sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Declaration): A null
procedure cannot be a protected operation (it is a basic_declaration,
not a subprogram_declaration).
(Check_Overriding_Indicator): Rename formal Does_Override to Overridden_
Subp. Add logic for entry processing.
(Check_Synchronized_Overriding): New procedure in New_Overloaded_Entity.
Determine whether an entry or subprogram of a protected or task type
override an inherited primitive of an implemented interface.
(New_Overloaded_Entity): Add calls to Check_Synchronized_Overriding.
Update the actual used in calls to Check_Overriding_Indicator.
(Analyze_Generic_Subprogram_Body): If the subprogram is a child unit,
generate the proper reference to the parent unit, for cross-reference.
(Analyze_Subprogram_Declaration): Protect Is_Controlling_Formal with
Is_Formal.
Add -gnatd.l --Use Ada 95 semantics for limited function returns,
(Add_Extra_Formal): Revise procedure to allow passing in associated
entity, scope, and name suffix, and handle setting of the new
Extra_Formals field.
(Create_Extra_Formals): Change existing calls to Add_Extra_Formal to
pass new parameters. Add support for adding the new extra access formal
for functions whose calls are treated as build-in-place.
(Analyze_A_Return_Statement): Correct casing in error message.
Move Pop_Scope to after Analyze_Function_Return, because an extended
return statement really is a full-fledged scope. Otherwise, visibility
doesn't work right. Correct use of "\" for continuation messages.
(Analyze_Function_Return): Call Analyze on the Obj_Decl, rather than
evilly trying to call Analyze_Object_Declaration directly. Otherwise,
the node doesn't get properly marked as analyzed.
(Analyze_Subprogram_Body): If subprogram is a function that returns
an anonymous access type that denotes a task, build a Master Entity
for it.
(Analyze_Return_Type): Add call to Null_Exclusion_Static_Checks. Verify
proper usage of null exclusion in a result definition.
(Process_Formals): Code cleanup and new error message.
(Process_Formals): Detect incorrect application of null exclusion to
non-access types.
(Conforming_Types): Handle conformance between [sub]types and itypes
generated for entities that have null exclusions applied to them.
(Maybe_Primitive_Operation): Add an additional type retrieval when the
base type is an access subtype. This case arrises with null exclusions.
(New_Overloaded_Entity): Do not remove the overriden entity from the
homonym chain if it corresponds with an abstract interface primitive.
(Process_Formals): Replace membership test agains Incomplete_Kind with a
call to the synthesized predicate Is_Incomplete_Type.
(Analyze_Subprogram_Body): Check wrong placement of abstract interface
primitives.
(Analyze_Subprogram_Declaration): Check that abstract interface
primitives are abstract or null.
(Analyze_Subprogram_Specification): Remove previous check for abstract
interfaces because it was not complete.
(Has_Interface_Formals): Removed.

warn on infinite loops.
Add \\ to some continuation messages
(Analyze_Assignment_Statement): Call Warn_On_Useless_Assignment
(Process_Bounds): If the bounds are integer literals that result from
constant-folding, and they carry a user-defined type, preserve that type
rather than treating this as an integer range.
(Analyze_Exit_Statement): Test for E_Return_Statement in legality check.
(Analyze_Goto_Statement): Test for E_Return_Stateemnt in legality check.
(Analyze_Assignment_Statement): Add call to Check_Elab_Assign for
left hand side of assignment.
(Analyze_Assignment): Add suport to manage assigments to the attribute
priority of a protected object.
(Check_Possible_Current_Value_Condition): Allow fully qualified names
not just identifiers.
(Check_Possible_Current_Value_Condition): Acquire left operand of AND
or AND THEN for possible tracking.
(Analyze_Iteration_Scheme): Check for setting Current_Value for the
case of while loops so we can track values in the loop body.

* sem_ch4.adb (Try_Primitive_Operation): Code cleanup to ensure that we
generate the same errors compiling under -gnatc.
(Try_Object_Operation): If no candidate interpretation succeeds, but
there is at least one primitive operation with the right name, report
error in call rather than on a malformed selected component.
(Analyze_Selected_Component): If the prefix is an incomplete type from
a limited view, and the full view is available, use the full view to
determine whether this is a prefixed call to a primitive operation.
(Operator_Check): Verify that a candidate interpretation is a binary
operation before checking the type of its second formal.
(Analyze_Call): Add additional warnings for function call contexts not
yet supported.
(Analyze_Allocator): Move the check for "initialization not allowed for
limited types" after analyzing the expression. This is necessary,
because OK_For_Limited_Init looks at the structure of the expression.
Before analysis, we don't necessarily know what sort of expression it
is. For example, we don't know whether F(X) is a function call or an
indexed component; the former is legal in Ada 2005; the latter is not.
(Analyze_Allocator): Correct code for AI-287 -- extension aggregates
were missing. We also didn't handle qualified expressions. Now also
allow function calls. Use new common routine OK_For_Limited_Init.
(Analyze_Type_Conversion): Do not perform some legality checks in an
instance, because the error message will be redundant or spurious.
(Analyze_Overloaded_Selected_Component): Do not do style check when
setting an entity, since we do not know it is the right entity yet.
(Analyze_Selected_Component): Move Generate_Reference call to Sem_Res
(Analyze_Overloaded_Selected_Component): Same change
(Analyze_Selected_Component): Remove unnecessary prefix type retrieval
since regular incomplete subtypes are transformed into corresponding
subtypes of their full views.
(Complete_Object_Operation): Treat name of transformed subprogram call
as coming from source, for browsing purposes.
(Try_Primitive_Operation): If formal is an access parameter, compare
with base type of object to determine whether it is a primitive
operation.
(Operator_Check): If no interpretation of the operator matches, check
whether a use clause on any candidate might make the operation legal.
(Try_Class_Wide_Operation): Check whether the first parameter is an
access type whose designated type is class-wide.

(New_Stream_Subprogram): When processing an attribute definition clause
for a stream-oriented subprogram, record an entity node occurring at
the point of clause to use for checking the visibility of the clause,
as defined by 8.3(23) as amended by AI-195.
(New_Stream_Subprogram): New procedure, factoring behaviour from both
New_Stream_Function and New_Stream_Procedure.
(New_Stream_Function, New_Stream_Procedure): Removed.

* sem_ch12.ads, sem_ch12.adb (Save_References): If node is an operator
that has been constant-folded, preserve information of original tree,
for ASIS uses.
(Analyze_Formal_Derived_Type): Set the limited present flag of the newly
generated private extension declaration if the formal derived type is
synchronized. Carry synchronized present over to the generated private
extension.
(Validate_Derived_Type_Instance): Ensure that the actual of a
synchronized formal derived type is a synchronized tagged type.
(Instantiate_Formal_Package): When creating the instantiation used to
validate the actual package of a formal declared without a box, check
whether the formal itself depends on a prior actual.
(Instantiate_Formal_Subprogram): Create new entities for the defining
identifiers of the formals in the renaming declaration, for ASIS use.
(Instantiate_Formal_Subprogram, Instantiate_Formal_Type): When creating
a renaming declaration or a subtype declaration for an actual in an
instance, capture location information of declaration in generic, for
ASIS use.
(Instantiate_Formal_Package): Add comments on needed additional tests.
AI-317 (partial parametrization) is fully implemented.
(Validate_Private_Type_Instance): Add check for actual which
must have preelaborable initialization
Use new // insertion for some continuation messages
(Analyze_Formal_Object_Declaration): Change usage of Expression to
Default_Expression. Add type retrieval when the declaration has an
access definition. Update premature usage of incomplete type check.
(Check_Access_Definition): New subsidiary routine. Check whether the
current compilation version is Ada 05 and the supplied node has an
access definition.
(Instantiate object): Alphabetize local variables. Handle the creation
of new renaming declarations with respect to the kind of definition
used - either an access definition or a subtype mark. Guard against
unnecessary error message in the context of anonymous access types after
they have been resolved. Add check for required null exclusion in a
formal object declaration.
(Switch_View): A private subtype of a non-private type needs to be
switched (the base type can have been switched without its private
dependents because of the last branch of Check_Private_View.
(Check_Private_View): Do not recompute Base_Type (T), instead use cached
value from BT.
(Instantiate_Type): Emit an error message whenever a class-wide type of
a tagged incomplete type is used as a generic actual.
(Find_Actual_Type): Extend routine to handle a component type in a child
unit that is imported from a formal package in a parent.
(Validate_Derived_Type_Instance): Check that analyzed formal and actual
agree on constrainedness, rather than checking against ultimate ancestor
(Instantiate_Subprogram_Body): Create a cross-reference link to the
generic body, for navigation purposes.

* sem_attr.ads, sem_attr.adb (Analyze_Access_Attribute): Diagnose
properly an attempt to apply Unchecked_Access to a protected operation.
(OK_Self_Reference): New subprogram to check the legality of an access
attribute whose prefix is the type of an enclosing aggregate.
Generalizes previous mechanism to handle attribute references nested
arbitrarily deep within the aggregate.
(Analyze_Access_Attribute): An access attribute whose prefix is a type
can appear in an aggregate if this is a default-initialized aggregate
for a self-referential type.
(Resolve_Attribute, case Access): Ditto.
Add support for new implementation defined attribute Stub_Type.
(Eval_Attribute, case Attribute_Stub_Type): New case.
(Analyze_Attribute, case Attribute_Stub_Type): New case.

(Resolve_Attribute, case 'Access et al): Take into account anonymous
access types of return subtypes in extended return statements. Remove
accessibility checks on anonymous access types when Unchecked_Access is
used.
(Analyze_Attribute): Add support for the use of 'Class to convert
a class-wide interface to a tagged type.
Add support for the attribute Priority.
(Resolve_Attribute, case Attribute_Access): For Ada_05, add test for
whether the designated type is discriminated with a constrained partial
view and require static matching in that case.
Add local variable Des_Btyp. The Designated_Type
of an access to incomplete subtype is either its non-limited view if
coming from a limited with or its etype if regular incomplete subtype.
* sem_cat.ads, sem_cat.adb (Validate_Remote_Access_To_Class_Wide_Type):
Fix predicate to identify and allow cases of (expander-generated)
references to tag of designated object of a RACW.
(Validate_Static_Object_Name): In Ada 2005, a formal object is
non-static, and therefore cannot appear as a primary in a preelaborable
package.
(Has_Stream_Attribute_Definition): New subprogram, abstracted from
Has_Read_Write_Attributes.
(Has_Read_Write_Attributes): Reimplement in termes of
Has_Stream_Attribute_Definition.

this too early, or we cannot implement avoiding the messages in the
case of obsolescent units withing obsolescent units).

an ancestor of the current compilation unit, find whether there is
a sibling child unit that is immediately visible.

the analysis of the private part of a nested package, to remove from
visibility the private with_clauses of the enclosing package
declaration.
(Analyze_With_Clause): Remove Check_Obsolescent call, this checking is

(Install_Limited_Context_Clauses): Remove superfluous error
message associated with unlimited view visible through use

is reported, we add the backslash to the text of the error
to ensure that it is reported as a single error message.
Use new // insertion for some continuation messages
(Expand_Limited_With_Clause): Use copy of name rather than name itself,

rules about returning limited types in function Create_AST_Handler in
s-asthan.adb.
* sem.adb (Analyze): Add cases for new node kinds
N_Extended_Return_Statement and N_Return_Object_Declaration.
* sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
type is in the same category as type of context before applying check,
to prevent anomalies in instantiations.
(Resolve_Aggregate): Remove test for limited components in aggregates.
It's unnecessary in Ada 95, because if it has limited components, then
it must be limited. It's wrong in Ada 2005, because limited aggregates
are now allowed.
(Resolve_Record_Aggregate): Move check for limited types later, because
OK_For_Limited_Init requires its argument to have been resolved.
(Get_Value): When copying the component default expression for a
defaulted association in an aggregate, use the sloc of the aggregate
and not that of the original expression, to prevent spurious
elaboration errors, when the expression includes function calls.
(Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
were missing. We also didn't handle qualified expressions. Now also
allow function calls. Use new common routine OK_For_Limited_Init.
(Resolve_Extension_Aggregate): Minor fix to bad error message (started
with space can upper case letter).
* sem_ch3.ads, sem_ch3.adb (Create_Constrained_Components): Set
Has_Static_Discriminants flag
(Record_Type_Declaration): Diagnose an attempt to declare an interface
type with discriminants.
(Process_Range_Expr_In_Decl): Do validity checks on range
(Build_Discriminant_Constraints): Use updated form of
Denotes_Discriminant.
(Process_Subtype): If the subtype is a private subtype whose full view
is a concurrent subtype, introduce an itype reference to prevent scope
anomalies in gigi.
(Build_Derived_Record_Type, Collect_Interface_Primitives,
Record_Type_Declaration): The functionality of the subprograms
Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
is now performed by a single routine.
(Build_Derived_Record_Type): If the type definition includes an explicit
indication of limitedness, then the type must be marked as limited here
to ensure that any access discriminants will not be treated as having
a local anonymous access type.
(Check_Abstract_Overriding): Issue a detailed error message when an
abstract subprogram was not overridden due to incorrect mode of its
first parameter.
(Analyze_Private_Extension_Declaration): Add support for the analysis of
synchronized private extension declarations. Verify that the ancestor is
a limited or synchronized interface or in the generic case, the ancestor
is a tagged limited type or synchronized interface and all progenitors
are either limited or synchronized interfaces.
Derived_Type_Declaration): Check for presence of private extension when
dealing with synchronized formal derived types.
Process_Full_View): Enchance the check done on the usage of "limited" by
testing whether the private view is synchronized.
Verify that a synchronized private view is completed by a protected or
task type.
(OK_For_Limited_Init_In_05): New function.
(Analyze_Object_Declaration): Move check for limited types later,
because OK_For_Limited_Init requires its argument to have been resolved.
Add -gnatd.l --Use Ada 95 semantics for limited function returns,
in order to alleviate the upward compatibility introduced by AI-318.
(Constrain_Corresponding_Record): If the constraint is for a component
subtype, mark the itype as frozen, to avoid out-of-scope references to
discriminants in the back-end.
(Collect_Implemented_Interfaces): Protect the recursive algorithm of
this subprogram against wrong sources.
(Get_Discr_Value, Is_Discriminant): Handle properly references to a
discriminant of limited type completed with a protected type, when the
discriminant is used to constrain a private component of the type, and
expansion is disabled.
(Find_Type_Of_Object): Do not treat a return subtype that is an
anonymous subtype as a local_anonymous_type, because its accessibility
level is the return type of the enclosing function.
(Check_Initialization): In -gnatg mode, turn the error "cannot
initialize entities of limited type" into a warning.
(OK_For_Limited_Init): Return true for generated nodes, since it
sometimes violates the legality rules.
(Make_Incomplete_Declaration): If the type for which an incomplete
declaration is created happens to be the currently visible entity,
preserve the homonym chain when removing it from visibility.
(Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
inherited subprograms.
(Access_Definition): If this is an access to function that is the return
type of an access_to_function definition, context is a type declaration
and the scope of the anonymous type is the current one.
(Analyze_Subtype_Declaration): Add the defining identifier of a regular
incomplete subtype to the set of private dependents of the original
incomplete type.
(Constrain_Discriminated_Type): Emit an error message whenever an
incomplete subtype is being constrained.
(Process_Incomplete_Dependents): Transform an incomplete subtype into a
corresponding subtype of the full view of the original incomplete type.
(Check_Incomplete): Properly detect invalid usage of incomplete types
and subtypes.

(Expand_Inlined_Call): Tagged types are by-reference types, and
therefore should be replaced by a renaming declaration in the expanded
body, as is done for limited types.
(Expand_Call): If this is a call to a function with dispatching access
result, propagate tag from context.
(Freeze_Subprogram): Enable full ABI compatibility for interfacing with
CPP by default.
(Make_Build_In_Place_Call_In_Assignment): New procedure to do
build-in-place when the right-hand side of an assignment is a
build-in-place function call.
(Make_Build_In_Place_Call_In_Allocator): Apply an unchecked conversion
of the explicit dereference of the allocator to the result subtype of
the build-in-place function. This is needed to satisfy type checking
in cases where the caller's return object is created by an allocator for
a class-wide access type and the type named in the allocator is a
specific type.
(Make_Build_In_Place_Call_In_Object_Declaration): Apply an unchecked
conversion of the reference to the declared object to the result subtype
of the build-in-place function. This is needed to satisfy type checking
in cases where the declared object has a class-wide type. Also, in the
class-wide case, change the type of the object entity to the specific
result subtype of the function, to avoid passing a class-wide object
without explicit initialization to the back end.
(Register_Interface_DT_Entry): Moved outside the body of
Freeze_Subprogram because this routine is now public; it is called from
Check_Dispatching_Overriding to handle late overriding of abstract
interface primitives.
(Add_Access_Actual_To_Build_In_Place_Call): New utility procedure for

(Is_Build_In_Place_Function_Call): New function to determine whether an

(Make_Build_In_Place_Call_In_Anonymous_Context): New procedure for
handling calls to build-in-place functions in contexts that do not
involve init of a separate object (for example, actuals of subprogram
calls).
(Make_Build_In_Place_Call_In_Object_Declaration): New procedure for
handling calls to build-in-place functions as the initialization of an

(Check_Overriding_Inherited_Interfaces): Removed.

(Expand_Inlined_Call.Rewrite_Procedure_Call): Do not omit block around
inlined statements if within a transient scope.
(Expand_Inlined_Call.Process_Formals): When replacing occurrences of
formal parameters with occurrences of actuals in inlined body, establish
visibility on the proper view of the actual's subtype for the body's
context.
(Freeze_Subprogram): Do nothing if we are compiling under full ABI
compatibility mode and we have an imported CPP subprogram because
for now we assume that imported CPP primitives correspond with
objects whose constructor is in the CPP side (and therefore we
don't need to generate code to register them in the dispatch table).
(Expand_Actuals): Introduce copy of actual, only if it might be a bit-
aligned selected component.
(Add_Call_By_Copy_Node): Add missing code to handle the case in which
the actual of an in-mode parameter is a type conversion.
