a-tags.ads, a-tags.adb:

2006-10-31  Javier Miranda  <miranda@adacore.com>

	* a-tags.ads, a-tags.adb: 
	(Predefined_DT): New function that improves readability of the code.
	(Get_Predefined_Prim_Op_Address, Set_Predefined_Prim_Op_Address,
	Inherit_DT): Use the new function Predefined_DT to improve code
	readability.
	(Register_Interface_Tag): Update assertion.
	(Set_Interface_Table): Update assertion.
	(Interface_Ancestor_Tags): New subprogram required to implement AI-405:
	determining progenitor interfaces in Tags.
	(Inherit_CPP_DT): New subprogram.

        * exp_disp.adb (Expand_Interface_Thunk): Suppress checks during the
	analysis of the thunk code.
        (Expand_Interface_Conversion): Handle run-time conversion of
        access to class wide types.
	(Expand_Dispatching_Call): When generating the profile for the
	subprogram itype for a dispatching operation, properly terminate the
	formal parameters chaind list (set the Next_Entity of the last formal
	to Empty).
	(Collect_All_Interfaces): Removed. This routine has been moved to
	sem_util and renamed as Collect_All_Abstract_Interfaces.
	(Set_All_DT_Position): Hidden entities associated with abstract
	interface primitives are not taken into account in the check for
	3.9.3(10); this check is done with the aliased entity.
	(Make_DT, Set_All_DT_Position): Enable full ABI compatibility for
	interfacing with CPP by default.
	(Expand_Interface_Conversion): Add missing support for static conversion
	from an interface to a tagged type.
	(Collect_All_Interfaces): Add new out formal containing the list of
	abstract interface types to cleanup the subprogram Make_DT.
	(Make_DT): Update the code to generate the table of interfaces in case
	of abstract interface types.
	(Is_Predefined_Dispatching_Alias): New function that returns true if
	a primitive is not a predefined dispatching primitive but it is an
	alias of a predefined dispatching primitive.
	(Make_DT): If the ancestor of the type is a CPP_Class and we are
	compiling under full ABI compatibility mode we avoid the generation of
	calls to run-time services that fill the dispatch tables because under
	this mode we currently inherit the dispatch tables in the IP subprogram.
	(Write_DT): Emit an "is null" indication for a null procedure primitive.
	(Expand_Interface_Conversion): Use an address as the type of the formal
	of the internally built function that handles the case in which the
	target type is an access type.
