* exp_ch6.ads, exp_ch6.adb: Use new Validity_Check suppression
capability.
(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
adding an implicit access actual on a call to a build-in-place function.

entity is a function whose calls should be handled as build-in-place.
(Is_Build_In_Place_Function_Call): New function to determine whether an
expression is a function call that should handled as build-in-place.
(Make_Build_In_Place_Call_In_Allocator): New procedure for handling
calls to build-in-place functions as the initialization of an allocator.
(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
object declaration.
(Detect_Infinite_Recursion): Add explicit parameter Process to
instantiation of Traverse_Body to avoid unreferenced warning.
(Check_Overriding_Inherited_Interfaces): Removed.
(Register_Interface_DT_Entry): Code cleanup.
(Register_Predefined_DT_Entry): Code cleanup.
(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.
(Expand_Actuals): If the call does not come from source and the actual
is potentially misaligned, let gigi handle it rather than rejecting the
(Expand_N_Subprogram_Body, Freeze_Subprogram): set subprograms returning
Class Wide types as returning by reference independantly of their
controlled status since with HIE runtimes class wide types are not
potentially controlled anymore.

(Expand_Allocator_Expression): Suppress the call to Remove_Side_Effects
when the allocator is initialized by a build-in-place call, since the
allocator is already rewritten as a reference to the function result,
and this prevents an unwanted duplication of the function call.
Add with and use of Exp_Ch6.

Make_Build_In_Place_Call_In_Allocator to the call (for both tagged and

* exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
register in the final list objects containing class-wide interfaces;
otherwise we incorrectly register the tag of the interface in the final
list.
(Make_Controlling_Function_Wrappers): Add missing barrier to do not
generate the wrapper if the parent primitive is abstract. This is
required to report the correct error message.
(Expand_N_Subtype_Indication): Do validity checks on range
(Clean_Task_Names): If an initialization procedure includes a call to
initialize a task (sub)component, indicate that the procedure will use
the secondary stack.

with respect to E.2.2(14) when it finally is frozen.
(Build_Initialization_Call,Expand_Record_Controller): Rename
Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
return-by-reference has no meaning in Ada 2005.
(Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
to register tag of the immediate ancestor interfaces in the
run-time structure.
(Init_Secondary_Tags): Moved to the specification to allow the
initialization of extension aggregates with abstract interfaces.
(Build_Master_Renaming): Make public, for use by function declarations
whose return type is an anonymous access type.

(Expand_Tagged_Root): Update documentation in its specification.

directly from the ancestor.

(Is_Null_Interface_Procedure): New function in
Make_Null_Procedure_Specs.
(Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
immediate ancestor of a tagged type is an abstract interface type we
must generate the specification of the predefined primitives associated
with controlled types (because the dispatch table of the ancestor is
null and hence these entries cannot be inherited). This is required to
elaborate well the dispatch table.

(Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,

dispatching entries (__gl_priority_specific_dispatching and
__gl_num_specific_dispatching).

partition.

is the upper case first character of the policy name.
(__gnat_set_globals): Now a dummy function.
(__gnat_handle_vms_condition): Feed adjust_context_for_raise with
mechargs instead of sigargs, as the latter can be retrieved from the

mechargs argument.
(__gnat_adjust_context_for_raise, ia64-vms): New function.

(Resolve_Arithmetic_Op): Do not give an error on calls to the
universal_fixed "*" and "/" operators when they are used in a context

Check for Current_Task usage now includes entry barrier, and is now a
warning, not an error.
