	Refactored encoding code into objc-encoding.h and objc-encoding.c.
	* objc-act.c (util_obstack, util_firstobj, encode_type_qualifiers,
	encode_type, generating_instance_variables, objc_method_parm_type,
	objc_encoded_type_size, encode_method_prototype,
	objc_build_encode_expr, pointee_is_readonly, encode_pointer,
	encode_array, encode_vector, encode_aggregate_fields,
	encode_aggregate_within, encode_next_bitfield,
	encode_gnu_bitfield, encode_field_decl,
	objc_v2_encode_property_attr): Moved to objc-encoding.h and
	objc-encoding.c.  No change in the actual code.
	Include objc-encoding.h.
	(objc_init): Added TODO.
	(objc_build_property_setter_name): Made non-static so it can be
	called from objc-encoding.c.
	* objc-act.h (OBJC_ENCODE_INLINE_DEFS,
	OBJC_ENCODE_DONT_INLINE_DEFS): Moved to objc-encoding.h.
	* objc-runtime-shared-support.h (objc_v2_encode_property_attr,
	encode_method_prototype, encode_field_decl,
	generating_instance_variables): Moved to objc-encoding.h.	
	(objc_build_property_setter_name): Declare.
	* objc-encoding.c: New.
	* objc-encoding.h: New.
	* objc-gnu-runtime-abi-01.c: Include objc-encoding.h.
	* objc-next-runtime-abi-01.c: Likewise.
	* objc-next-runtime-abi-02.c: Likewise.	
	* objc-runtime-shared-support.c: Likewise.
	* Make-lang.in (OBJC_OBJS): Added objc-encoding.o.
	(objc/objc-lang.o): Reordered dependencies.
	(objc/objc-runtime-shared-support.o): Reordered dependencies.
	Added dependencies on objc-encoding.h and on $(GGC_H),
	$(DIAGNOSTIC_CORE_H), $(FLAGS_H) and input.h.
	(objc/objc-gnu-runtime-abi-01.o): Likewise.
	(objc/objc-next-runtime-abi-01.o): Likewise.
	(objc/objc-next-runtime-abi-02.o): Likewise.
	(objc/objc-act.o): Reordered dependencies.  Added dependency on
	objc-encoding.h.
	(objc/objc-encoding.o): New rule.

	* objc-encoding.c (encode_type): Use "%<%T%>" format when printing
	warning "unknown type %<%T%> found during Objective-C encoding"
	instead of using gen_type_name.
	
In gcc/objcp/:
2011-07-04  Nicola Pero  <nicola.pero@meta-innovation.com>

	* Make-lang.in (OBJCXX_OBJS): Added objc-encoding.o.
	(objcp/objcp-lang.o): Reordered dependencies.  Depend on GGC_H.
	(objcp/objcp-decl.o): Reordered dependencies.
	(objcp/objc-runtime-shared-support.o): Reordered dependencies.
	Updated them to be identical to the corresponding new objc/ ones,
	with the addition of objcp-decl.h.
	(objcp/objc-runtime-shared-support.o): Likewise.
	(objcp/objc-gnu-runtime-abi-01.o): Likewise.
	(objcp/objc-next-runtime-abi-01.o): Likewise.
	(objcp/objc-next-runtime-abi-02.o): Likewise.
	(objcp/objcp-act.o): Reordered dependencies.  Added dependency on
	objc-encoding.h.
	(objcp/objc-encoding.o): New rule.
