* sem_util.ads, sem_util.adb (Object_Access_Level): If the object is a
dereference of a local object R created as a reference to another
object O, use the access level of O.
(Matches_Prefixed_View_Profile): Use common predicate Conforming_Types,
rather than local Same_Formal_Type, to check whether protected operation
overrides an inherited one.
(Same_Formal_Type): New predicate, used when matching signatures of
overriding synchronized operations, to handle the case when a formal
has a type that is a generic actual.
(Is_Aliased_View): Replace check on E_Task_Type and E_Protected_Type by
predicate Is_Concurrent_Type. This ensures supportin case of subtypes.
(Needs_One_Actual): New predicate, for Ada 2005 use, to resolve
syntactic ambiguities involving indexing of function calls that return
arrays.
(Abstract_Interface_List): New subprogram that returns the list of
abstract interfaces associated with a concurrent type or a
concurrent record type.
(Interface_Present_In_Parent): New subprogram used to check if a
given type or some of its parents implement a given interface.
(Collect_Abstract_Interfaces): Add support for concurrent types
with interface types.
(Has_Abstract_Interfaces): Add support for concurrent types with
interface types.
(Is_Parent): New subprogram that determines whether E1 is a parent
of E2. For a concurrent type its parent is the first element of its
list of interface types; for other types this function provides the
same result than Is_Ancestor.
(Enclosing_Subprogram): Add test for N_Extended_Return_Statement.
(Collect_Synchronized_Interfaces): Removed because the subprogram
Collect_Abstract_Interfaces provides this functionality.
(Collect_Abstract_Interfaces): Minor update to give support to

* sem_ch7.ads, sem_ch7.adb (Inspect_Deferred_Constant_Completion): Move
out of Analyze_Package_Declaration, because processing must be applied
to package bodies as well, for deferred constants completed by pragmas.
(Analyze_Package_Declaration): When the package declaration being
analyzed does not require an explicit body, call Check_Completion.
(May_Need_Implicit_Body): An implicit body is required when a package
spec contains the declaration of a remote access-to-classwide type.
(Analyze_Package_Body): If the package contains RACWs, append the
pending subprogram bodies generated by exp_dist at the end of the body.
(New_Private_Type,Unit_Requires_Body): Split Is_Abstract flag into
Is_Abstract_Subprogram and Is_Abstract_Type.
(Preserve_Full_Attributes): The full entity list is not an attribute
that must be preserved from full to partial view.
* sem_dist.adb (Add_RAS_Dereference_TSS):
Change primitive name to _Call so it cannot clash with any legal
identifier, and be special-cased in Check_Completion.
Mark the full view of the designated type for the RACW associated with
a RAS as Comes_From_Source to get proper view switching when installing

* sem_ch4.adb (Try_Primitive_Operation): The call is legal if the
prefix type is a discriminated subtype of the type of the formal.
(Analyze_Allocator): Collect all coextensions regardless of the context.
Whether they can be allocated statically is determined in exp_ch4.
(Analyze_Selected_Component): If the prefix is a limited view and the
non-limited view is available, use the non-limited one.
(Operator_Check): For "X'Access = Y'Access" (which is ambiguous, and
therefore illegal), suggest a qualified expression rather than a type
conversion, because a type conversion would be illegal in this context.
(Anayze_Allocator): Trace recursively all nested allocators so that all
coextensions are on the corresponding list for the root. Do no mark
coextensions if the root allocator is within a declaration for a stack-
allocated object, because the access discriminants will be allocated on
the stack as well.
(Analyze_Call): Remove restriction on calls to limited functions for the
cases of generic actuals for formal objects, defaults for formal objects
and defaults for record components.
(Analyze_Allocator): Before analysis, chain coextensions on the proper
element list. Their expansion is delayed until the enclosing allocator
is processed and its finalization list constructed.
(Try_Primitive_Operation): If the prefix is a concurrent type, looks
for an operation with the given name among the primitive operations of
the corresponding record type.
(Analyze_Selected_Component): If the prefix is a task type that
implements an interface, and there is no entry with the given name,
check whether there is another primitive operation (e.g. a function)
with that name.
(Try_Object_Operation, Analyze_One_Call, Try_Indexed_Call): Handle
properly the indexing of a function call written in prefix form, where
the function returns an array type, and all parameters of the function
except the first have defaults.
(Analyze_Equality_Op): If this is a call to an implicit inequality, keep
the original operands, rather than relocating them, for efficiency and
to work properly when an operand is overloaded.
(Analyze_Allocator,Operator_Check,Remove_Abstract_Operations): Split
Is_Abstract flag into Is_Abstract_Subprogram and Is_Abstract_Type.
(Analyze_Selected_Component): If the prefix is a private extension, only
scan the visible components, not those of the full view.
(Try_Primitive_Operation): If the operation is a procedure, collect all
possible interpretations, as for a function, because in the presence of
classwide parameters several primitive operations of the type can match
the given arguments.

* sem_ch12.adb (Check_Generic_Actuals): Use first subtype of actual
when capturing size information, instead of base type, which for a
formal array type will be the unconstrained type.
(Analyze_Formal_Object_Declaration): Add check for illegal default
expressions for a formal in object of a limited type.
(Instantiate_Object): Ditto.
(Check_Formal_Package_Instance): Skip entities that are formal objects,
because they were defaulted in the formal package and no check applies
to them.
(Check_Formal_Package_Instance): Extend conformance check to other
discrete types beyond Integer.
(Process_Default): Copy directly the unmatched formal. A generic copy
has already been performed in Analyze_Formal_Package.
(Analyze_Associations): If a formal subprogram has no match, check for
partial parametrization before looking for a default, to prevent
spurious errors.
(Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation): Do
not set the instantiation environment before analyzing the actuals.
Fixes regression on 8515-003 with implementation of AI-133.
Set_Instance_Env checks whether the generic unit is a predefined
unit, in which case the instance must be analyzed with the latest Ada
mode. This setting must take place after analysis of the actuals,
because the actuals must be analyzed and frozen in the Ada mode extant
outside of the current instantiation.
(Save_Env, Restore_Env): Preserve and restore the configuration
parameters so that predefined units can be compiled in the proper Ada
mode.
(Analyze_Formal_Object_Declaration,Analyze_Formal_Subprogram,
Instantiate_Type): Split Is_Abstract flag into Is_Abstract_Subprogram

(Non_VMS_Usage): Document that gnatstack accept project file switches.
(GNATCmd): Update the B_Start variable if we are in a VMS environment.
Add gnatstack to the list of commands that use project file related
switches, and get the single attribute Switches from the stack package
in a project file when calling gnatstack. Parse the -U flag for
processing files belonging to all projects in the project tree.
Remove all processing for command Setup

an association with a box as providing a value even though the
initialization procedure for the type is not available.

box corresponds to a component of the type.
(Resolve_Record_Aggregate): Split Is_Abstract flag into
Is_Abstract_Subprogram and Is_Abstract_Type.
* exp_tss.adb (Base_Init_Proc): Use Is_Type instead of Type_Kind for
assert.

* exp_intr.adb (Expand_Exception_Call): Calls to subprograms in
GNAT.Current_Exception are not allowed if pragma Restrictions
(No_Exception_Propagation) is set and in any case make the associated
handler unsuitable as a target for a local raise statement.
(Expand_Dispatching_Constructor_Call): Replace generation of call to the
run-time subprogram CW_Membership by call to Build_CW_Membership.
(Expand_Dispatching_Constructor_Call): If the dispatching tag is given
by a function call, a temporary must be created before expanding the
Constructor_Call itself, to prevent out-of-order elaboration in the
back-end when stack checking is enabled..

* exp_dist.ads, exp_dist.adb (Build_To_Any_Call, Build_From_Any_Call):
Do an Unchecked_Conversion to handle the passage from the Underlying
Type to the Base Type when calling Build_To_Any_Call and
Build_From_Any_Call.
(Build_Actual_Object_Declaration): Set Object's Ekind to E_Variable or
E_Constant, depending upon Variable formal.
(GARLIC_Support.Build_Subprogram_Receiving_Stubs,
PolyORB_Support.Build_Subprogram_Receiving_Stubs): For a formal
parameter that requires an extra constrained parameter, declare
temporary for actual as a variable, not a constant.
(Add_RACW_Primitive_Declarations_And_Bodies): Generate bodies only when
the unit being compiled is the one that contains the stub type.
Change primitive operation name for the RACW associated with a RAS
from Call to _Call so it cannot clash with any legal identifier.
(PolyORB_Support.Add_RACW_Write_Attribute): Remove unused constant
Is_RAS.
(Append_RACW_Bodies): New subprogram.
(Expand_Receiving_Stubs_Bodies): Pass a 'Stmts' list to
Add_Receiving_Stubs_To_Declarations functions.
When expanding a package body, this list correspond to the
statements in the HSS at the end of the pacakge.
When expanding a package spec, this list correspond to the
spec declarations.
(Add_Receiving_Stubs_To_Declarations): Append the function
registering the receiving stubs at the end of the 'Stmts' list.
(RCI_Package_Locator): Pass the new Version generic formal when
instantiating a RCI_Locator package.
(Build_From_Any_Function): To compute the High bound for an
unconstrained array actual, we add the Low bound with the length.
Thus we must convert the low bound and the length to an appropriate
type before doing the sum.
(Build_Subprogram_Receiving_Stubs, PolyORB):
* Retrieve the extra formals parameters at the
end of the parameter stream.
* Use Move_Any_Value to write back out parameters
after executing the request as it is more efficient
than Copy_Any_Value.
* Build the any containing Extra Formals with the
appropriate typecode.
(PolyORB_Support.Helpers.Append_Record_Traversal): Nothing to do for an
empty Component_List.
(Build_Actual_Object_Declaration): New subprogram. Build and insert into
the tree the declaration for an object that serves as actual parameter
in server-side stubs.
(GARLIC_Support.Build_Subprogram_Receiving_Stubs,
PolyORB_Support.Build_Subprogram_Receiving_Stubs):
Use Build_Actual_Object_Declaration to prepare the actuals.
(Add_Parameter_To_NVList): Set the parameter mode to In for
Extra Constrained Parameters.
(Build_General_Calling_Stubs): Set the parameter type to boolean for
Extra Constrained parameters.
(Build_To_Any_Function, Build_From_Any_Function,
Built_TypeCode_Function): When Typ is implicit, call the correct
function with the first not implicit parent type.
(TC_Rec_Add_Process_Element, FA_Rec_Add_Process_Element,
(FA_Ary_Add_Process_Element): When Datum is an Any, we cannot infer the
typecode from the Etype. Therefore we retrieve the correct typecode
with a call to Get_Any_Type.
(Copy_Specification): Do controlling formal type substitution based on
Is_Controlling_Formal flag, instead of caller-provided object type.
(Build_Subprogram_Calling_Stubs): When retrieveing the original spec for
a RACW primitive operation, we might get a subprogram declaration for an
ancestor of the RACW designated type (not for the designated type
itself), in the case where this operation is inherited. In this case we
have no easy means of determining the original tagged type for which
the primitive was declared, so instead we now rely on
Copy_Specification to use the Is_Controlling_Formal flag to determine
which formals require type substitution.

(Build_Find_Body_Index): Adjust for above change.
(Entry_Index_Expression): Likewise.
(Is_Potentially_Large_Family): New function extracted from...
(Collect_Entry_Families): ...here. Call it to detect whether the family
is potentially large.
(Build_Entry_Count_Expression): If the family is potentially large, call
Family_Size with 'Cap' set to true.
(Expand_N_Protected_Type_Declaration, Expand_N_Protected_Body): Generate
a protected version of an operation declared in the private part of
a protected object, because they may be invoked through a callback.
(Set_Privals): If the type of a private component is an anonymous access
type, do not create a new itype for each protected body.
If the body of a protected operation creates
controlled types (including allocators for class-widetypes), the
body of the corresponding protected subprogram must include a
finalization list.
(Build_Activation_Chain_Entity): Build the chain entity for extended
return statements.
(Type_Conformant_Parameters): Use common predicate Conforming_Types
to determine whether operation overrides an inherited primitive.
(Build_Wrapper_Spec): Add code to examine the parents while looking
for a possible overriding candidate.
(Build_Simple_Entry_Call): Set No_Initialization on the object used to
hold an actual parameter value since its initialization is separated
from the the declaration. Prevents errors on null-excluding access
formals.

without a corresponding body, generate RACW subprogram bodies in the
spec (just as we do for the task activation call).

* exp_ch13.adb (Expand_External_Tag_Definition): Replace call to the
run-time subprogram Set_External_Tag by call to Build_Set_External_Tag.
* exp_ch4.adb (Expand_Allocator_Expression): Don't perform a run-time
accessibility on class-wide allocators if the allocator occurs at the
same scope level as the allocator's type. The check is guaranteed to
succeed in that case, even when the expression originates from a
parameter of the containing subprogram.
(Expand_N_Op_Eq): Do nothing in case of dispatching call if compiling
under No_Dispatching_Calls restriction. During the semantic analysis
we already notified such violation.
(Tagged_Membership): Constant folding. There is no need to check
the tag at run-time if the type of the right operand is non
class-wide abstract.
Replace call to Is_Ancestor by call to Is_Parent
to support concurrent types with interface types.

* exp_disp.ads, exp_disp.adb (Make_DT): Code reorganization to
initialize most the TSD components by means of an aggregate.
Modify the declaration of the object containing the TSD
because we now expand code that has a higher level of abstraction.
The TSD has a discriminant containing the Inheritance Depth Level,
value that is used in the membership test but also to fix the size
of the table of ancestors.
(Expand_Interface_Conversion): Insert function body at the closest place
to the conversion expression, to prevent access-before-elaboration
errors in the backend.
Code improved to reduce the size of the dispatch table if
compiling under restriction No_Dispatching_Calls plus code cleanup.
Code reorganization plus removal of calls to Set_Num_Prim_Ops
(Make_Secondary_DT): Remove call to Set_Num_Prim_Ops.
(Expand_Dispatching_Call): Minor code reorganization plus addition of
code to return immediately if compiling under No_Dispatching_Calls
restriction.

Set_Access_Level, Set_Expanded_Name, Set_Predefined_Prim_Op_Address,
Set_Prim_Op_Address, Set_RC_Offset, Set_Remotely_Callable, Set_TSD.
(Expand_Dispatching_Call): Replace generation of call to the run-time
subprograms Get_Predefined_Prim_Op_Address and Get_Prim_Op_Address by
calls to Build_Get_Predefined_Prim_Op_Address, and Build_Get_Prim_Op_
Address.
(Fill_DT_Entry, Fill_Secondary_DT_Entry): Replace generation of call to
the run-time subprograms Set_Predefined_Prim_Op_Address and Set_Prim_
Op_Address by calls to Build_Set_Predefined_Prim_Op_Address, and
Build_Set_Prim_Op_Address.
(Get_Remotely_Callable): Subprogram removed.
(Init_Predefined_Interface_Primitives): Replace generation of call to

First (Parameter_Associations ()) with the call to First_Actual that
returns an actual parameter expression for both named and positional
associations.

check violation of restriction No_Dispatching_Calls.

specify Any_Limited_Interface, and this functionality is already
provided by the function Has_Abstract_Interfaces.
(Find_Interface, Find_Interface_Tag, Find_Interface_ADT): Modified to
support concurrent types implementing interfaces.
