* exp_util.ads, exp_util.adb:
This patch replaces a number of occurrences of explicit tests for N_Null
with calls to Known_Null. This improves tracking of null values, since
Known_Null also catches null constants, and variables currently known to
be null, so we get better tracking.
(Ensure_Defined): create an itype reference only in the scope of the
itype.
(Side_Effect_Free): A selected component of an access type that
denotes a component with a rep clause must be treated as not
side-effect free, because if it is part of a linked structure its
value may be affected by a renaming.
(Expand_Subtype_From_Expr): For limited objects initialized with build
in place function calls, do nothing; otherwise we prematurely introduce
an N_Reference node in the expression initializing the object, which
breaks the circuitry that detects and adds the additional arguments to
the called function. Bug found working in the new patch for statically
allocated dispatch tables.
(Is_Library_Level_Tagged_Type): New subprogram.
(Remove_Side_Effects): If the expression of an elementary type is an
operator treat as a function call.
(Make_Literal_Range): If the index type of the array is not integer, use
attributes properly to compute the constraint on the resulting aggregate
which is a string.
* freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
class-wide type whose base type is an incomplete private type, leave
class-wide type unfrozen so that freeze nodes can be generated
properly at a later point.
(Freeze_Entity, array case): Handle case of pragma Pack and component
size attributre clause for same array.

* exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged
types declared in the declarative part of a nested package body or in
the proper body of a stub.
(Set_All_DT_Position): Add missing check to avoid wrong assignation
of the same dispatch table slot to renamed primitives.
(Make_Select_Specific_Data_Table): Handle private types.
(Tagged_Kind): Handle private types.
(Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg
output of implicit importation and exportation.
(Expand_Interface_Thunk): Fix bug in the expansion assuming that the
first formal of the thunk is always associated with the controlling
type. In addition perform the following code cleanup: remove formal
Thunk_Alias which is no longer required, cleanup evaluation of the
the controlling type, and update the documentation.
Replace occurrence of Default_Prim_Op_Count by
Max_Predef_Prims. Addition of compile-time check to verify
that the value of Max_Predef_Prims is correct.
(Check_Premature_Freezing): Apply check in Ada95 mode as well.
(Make_DT): Add parameter to indicate when type has been frozen by an
object declaration, for diagnostic purposes.
(Build_Static_Dispatch_Tables): New subprogram that takes care of the
construction of statically allocated dispatch tables.
(Make_DT): In case of library-level tagged types export the declaration
of the primary tag. Remove generation of tags (now done by Make_Tags).
Additional modifications to handle non-static generation of dispatch
tables. Take care of building tables for asynchronous interface types
(Make_Tags): New subprogram that generates the entities associated with
the primary and secondary tags of Typ and fills the contents of Access_
Disp_Table. In case of library-level tagged types imports the forward
declaration of the primary tag that will be declared later by Make_DT.
(Expand_Interface_Conversion): In case of access types to interfaces
replace an itype declaration by an explicit type declaration to avoid
problems associated with the scope of such itype in transient blocks.

* exp_ch3.ads, exp_ch3.adb (Add_Final_Chain): New subprogram.
(Freeze_Array_Type, Freeze_Record_Type): For the case of a component
type that is an anonymous access to controlled object, establish
an associated finalization chain to avoid corrupting the global
finalization list when a dynamically allocated object designated
by such a component is deallocated.
(Make_Controlling_Function_Wrappers): Create wrappers for constructor
functions that need it, even when not marked Requires_Overriding.
(Initialize_Tag): Replace call to has_discriminants by call to
Is_Variable_Size_Record in the circuitry that handles the
initialization of secondary tags.
(Is_Variable_Size_Record): New implementation.
(Expand_N_Object_Declaration): Suppress call to init proc if there is a
Suppress_Initialization pragma for a derived type.
(Is_Variable_Size_Record): New subprogram.
(Build_Offset_To_Top_Functions): New implementation that simplifies the
initial version of this routine and also fixes problems causing
incomplete initialization of the table of interfaces.
(Build_Init_Procedure): Improve the generation of code to initialize the
the tag components of secondary dispatch tables.
(Init_Secondary_Tags): New implementation that simplifies the previous
version of this routine.
(Make_DT): Add parameter to indicate when type has been frozen by an
object declaration, for diagnostic purposes.
(Check_Premature_Freezing): New subsidiary procedure of Make_DT, to
diagnose attemps to freeze a subprogram when some untagged type of its
profile is a private type whose full view has not been analyzed yet.
(Freeze_Array_Type): Generate init proc for packed array if either
Initialize or Normalize_Scalars is set.
(Make_Controlling_Function_Wrappers, Make_Null_Procedure_Specs): when
constructing the new profile, copy the null_exclusion indicator for each
parameter, to ensure full conformance of the new body with the spec.
* sem_type.ads, sem_type.adb (Make_Controlling_Function_Wrappers):
Create wrappers for constructor functions that need it, even when not
marked Requires_Overriding.
(Covers): Handle properly designated types of anonymous access types,
whose non-limited views are themselves incomplete types.
(Add_Entry): Use an entity to store the abstract operation which hides
an interpretation.
(Binary_Op_May_Be_Hidden): Rename to Binary_Op_Interp_Has_Abstract_Op.
(Collect_Interps): Use Empty as an actual for Abstract_Op in the
initialization aggregate.

(Set_May_Be_Hidden): Rename to Set_Abstract_Op.
(Write_Overloads): Output the abstract operator if present.

* exp_attr.adb (Expand_N_Attribute_Reference): Handle case of child unit
(Expand_N_Attribute_Reference): Further unify the handling of the
three forms of access attributes, using common code now for all three
cases. Add a test for the case of applying an access attribute to
an explicit dereference when the context is an access-to-interface
type. In that case we need to apply the conversion to the prefix
of the explicit dereference rather than the prefix of the attribute.
(Attribute_Version, UET_Address): Set entity as internal to ensure
proper dg output of implicit importation.
(Expand_Access_To_Type): Removed.
(Expand_N_Attribute_Reference): Merge the code from the three cases
of access attributes, since the processing is largely identical for
these cases. The substantive fix here is to process the case of a
type name prefix (current instance case) before handling the case
of interface prefixes.

* sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
generation of a freezing node to ensure proper management of null
excluding access types in the backend.
(Create_Extra_Formals): Test base type of the formal when checking for
the need to add an extra accessibility-level formal. Pass the entity E
on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
originally being done in a couple of cases), to ensure that the
Extra_Formals list gets set on the entity E when the first entity is
added.
(Conforming_Types): Add missing calls to Base_Type to the code that
handles anonymous access types. This is required to handle the
general case because Process_Formals builds internal subtype entities
to handle null-excluding access types.
(Make_Controlling_Function_Wrappers): Create wrappers for constructor
functions that need it, even when not marked Requires_Overriding.
Improve warnings for in out parameters
(Analyze_Function_Return): Warn for disallowed null return

types. This is required to generate the code of the null excluding
check (if required).
* sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
A formal parameter is never publicly referenceable outside of its body.
(Check_References): For an unreferenced formal parameter in an accept
statement, use the same warning circuitry as for subprogram formal
parameters.
(Warn_On_Unreferenced_Entity): New subprogram, taken from
Output_Unreferenced_Messages, containing the part of that routine that
is now reused for entry formals as described above.
(Goto_Spec_Entity): New function
(Check_References): Do not give IN OUT warning for dispatching operation
Improve warnings for in out parameters

parameters when deciding whether to apply a run-time accessibility
check.
(Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
aggregate code before allocator, and ahead of declaration for
temporary, to prevent access before elaboration when the allocator is
an actual for an access parameter.
(Expand_N_Type_Conversion): On an access type conversion involving an
access parameter, do not apply an accessibility check when the
operand's original node was an attribute other than 'Access. We now
create access conversions for the expansion of 'Unchecked_Access and
'Unrestricted_Access in certain cases and clearly accessibility should
not be checked for those.
* exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
includes a type conversion of a packed component that has been expanded,
recover the original expression for the object, and use this expression
in the post-call assignment statement, so that the assignment is made
to the object and not to a back-end temporary.
(Freeze_Subprogram): In case of primitives of tagged types not defined
at the library level force generation of code to register the primitive
in the dispatch table. In addition some code reorganization has been
done to leave the implementation clear.
(Expand_Call): When expanding an inherited implicit conversion,
preserve the type of the inherited function after the intrinsic
operation has been expanded.
