* einfo.adb (Itype_Printed): New flag
(Is_Limited_Type): Derived types do not inherit limitedness from
interface progenitors.
(Is_Return_By_Reference_Type): Predicate does not apply to limited
interfaces.
* einfo.ads (Itype_Printed): New flag
Move Is_Wrapper_Package to proper section
Add missing Inline for Is_Volatile
* output.ads, output.adb (Write_Erase_Char): New procedure
(Save/Restore_Output_Buffer): New procedures
(Save/Restore_Output_Buffer): New procedures
* sprint.ads, sprint.adb (Write_Itype): Handle case of record itypes
Add missing support for anonymous access type
(Write_Id): Insert calls to Write_Itype
(Write_Itype): New procedure to output itypes
* par-ch12.adb (P_Formal_Derived_Type_Definition): In Ada 2005, handle
use of "limited" in declaration.
* sinfo.ads, sinfo.adb:
Formal derived types can carry an explicit "limited" indication.
* sem_ch3.adb: Add with and use of Targparm.
(Create_Component): If Frontend_Layout_On_Target is True and the
copied component does not have a known static Esize, then reset
the size and positional fields of the new component.
(Analyze_Component_Declaration): A limited component is
legal within a protected type that implements an interface.
(Collect_Interfaces): Do not add to the list the interfaces that
are implemented by the ancestors.
(Derived_Type_Declaration): If the parent of the full-view is an
interface perform a transformation of the tree to ensure that it has
the same parent than the partial-view. This simplifies the job of the
expander in order to generate the correct object layout, and it is
needed because the list of interfaces of the full-view can be given in
any order.
(Process_Full_View): The parent of the full-view does not need to be
a descendant of the parent of the partial view if both parents are
interfaces.
(Analyze_Private_Extension_Declaration): If declaration has an explicit
"limited" the parent must be a limited type.
(Build_Derived_Record_Type): A derived type that is explicitly limited
must have limited ancestor and progenitors.
(Build_Derived_Type): Ditto.
(Process_Full_View): Verify that explicit uses of "limited" in partial
and full declarations are consistent.
(Find_Ancestor_Interface): Remove function.
(Collect_Implemented_Interfaces): New procedure used to gather all
implemented interfaces by a type.
(Contain_Interface): New function used to check whether an interface is
present in a list.
(Find_Hidden_Interface): New function used to determine whether two
lists of interfaces constitute a set equality. If not, the first
differing interface is returned.
(Process_Full_View): Improve the check for the "no hidden interface"
rule as defined by AI-396.
