* exp_ch3.adb (Make_Controlling_Function_Wrappers): generate wrapper a
wrapper when the full view of the controlling type of an inherited
function that dispatches on result implements interfaces.
(Expand_N_Object_Declaration): In cases where the type of the
declaration is anonymous access, create finalization list for it.
(Expand_N_Object_Declaration): Generate a persistent_bss directive only
if the object has no explicit initialization, to match description of
functionality of pragam Persistent_BSS.
(Build_Equivalent_Array_Aggregate, Build_Equivalent_Record_Aggregate):
new function to build static aggregates, to replace initialization call
when static initialization is desired.
(Freeze_Type): Generate a list controller for an access type whenever
its designated type has controlled anonymous access discriminants.
(Build_Equivalent_Aggregate): New procedure to compute a static
aggregate to be used as default initialization for composite types,
instead of a generating a call to the initialization procedure for the
type.
(Build_Initialization_Call): When available, replace a call to the
initialization procedure with a copy of the equivalent static aggregate
for the type.
(Expand_N_Object_Declaration): Use New_Occurrence_Of in generated
declarations for objects of a class-wide interface type, rather than
just identifiers, to prevent visibility problems.
(Expand_N_Object_Declaration): When expanding the declaration for an
object of a class-wide interface type, preserve the homonym chain of
the original entity before exchanging it with that of the generated
renaming declaration.
(Freeze_Enumeration_Type): Don't raise CE if No_Exception_Propagation
active, because there is no way to handle the exception.
(Freeze_Record_Type): In case of CPP_Class types add a call to Make_DT
to do a minimum decoration of the Access_Disp_Table list.
(Expand_Record_Controller): Avoid the addition of the controller between
the component containing the tag of a secondary dispatch table and its
adjacent component that stores the offset to the base of the object.
This latter component is only generated when the parent type has
discriminants ---documented in Add_Interface_Tag_Components).
(Apply_Array_Size_Check): Removed, no longer needed.
(Expand_N_Full_Type_Declaration): If the type has anonymous access
components, create a Master_Entity for it only if it contains tasks.
(Build_Init_Procedure): Suppress the tag assignment compiling under
no run-time mode.
(Freeze_Record_Type): Remove code associated with creation of dispatch
table.
(Init_Secondary_Tags): Update type of actuals when generating calls to
Ada.Tags.Set_Offset_To_Top
(Stream_Operation_OK): Disable use of streams compiling under no
run-time mode
(Expand_N_Object_Declaration): Don't do Initialize_Scalars initalization
if Has_Init_Expression set.
(Build_Init_Procedure): Replace call to Fill_DT_Entry by call to
Register_Primitive, which provides the same functionality.
(Requires_Init_Proc): Return false in case of interface types.
(Add_Secondary_Tables): Use the new attribute Related_Interface to
cleanup the code.
(Predefined_Primitive_Freeze): Do not assume that an internal entity
is always associated with a predefined primitive because the internal
entities associated with interface types are not predefined primitives.
Therefore, the call to Is_Internal is replaced by a call to the
function Is_Predefined_Dispatching_Operation.
(Make_Eq_If): When generating the list of comparisons for the
components of a given variant, omit the controller component that is
present if the variant has controlled components.
