        * objc-act.c (objc_add_dynamic_declaration_for_property): Do not
        search for the @property declation only in the current context,
        but also in inherited properties.  Do not mark the original
        PROPERTY_DECL in the @interface or @protocol with
        PROPERTY_DYNAMIC.
        (check_methods): To check if a method is associated with a
        @dynamic property, search for the property in IMPL_PROPERTY_DECL.
        (check_accessible_methods): Same change.
        * objc-act.h: Updated comment.

2010-11-08  Nicola Pero  <nicola.pero@meta-innovation.com>

        * objc-act.c (objc_add_synthesize_declaration_for_property):
        Iterate over IMPL_PROPERTY_DECL, not CLASS_PROPERTY_DECL, when
        checking for an existing @synthesize or @dynamic declaration.
        Search for an inherited @property declaration if none is found in
        the local interface.  If the required instance variable does not
        exist, return instead of trying to continue to prevent a compiler
        crash later.  Check that the instance variable is not already
        being used by another @synthesize.
        (objc_add_dynamic_declaration_for_property): Iterate over

        protocols and superclasses as well.

        * objc-act.c (lookup_property): When checking categories, also
        check the protocols attached to each.
        (objc_add_property_declaration): Determine the
        PROPERTY_SETTER_NAME and PROPERTY_GETTER_NAME here.  Tidied up
        error message.  Search for an existing property declaration with
        the same name which would be inherited from the class hiearchy,
        and produce an error if it has incompatible attributes.
        (check_methods): Changed second parameter.  If the method is a
        getter or setter for a property, do not warn if it is inherited as
        opposed to implemented directly in the class.
        (check_protocol): Updated calls to check_methods.
        (finish_class): Do not determine the PROPERTY_SETTER_NAME and
        PROPERTY_GETTER_NAME here; this is now done earlier, in
        objc_add_property_declaration.
        * objc-act.h (CLASS_NAME, CLASS_SUPER_NAME): Added comments.

        and code supporting them.  Fixed recovering when readonly and
        setter attributes are specified.  Removed support for @property in
        @implementation context.  Updated error message.  Double-check
        that a property does not have a DECL_INITIAL.  Validate the
        property assign semantics and emit appropriate errors and
        warnings.  Check for duplicate property declarations.  Set
        DECL_SOURCE_LOCATION, TREE_DEPRECATED, PROPERTY_NONATOMIC,
        PROPERTY_ASSIGN_SEMANTICS and PROPERTY_DYNAMIC of the new
        PROPERTY_DECL.  Do not set PROPERTY_COPIES.  Set
        PROPERTY_IVAR_NAME to NULL_TREE.
        (objc_build_getter_call): Renamed to
        objc_maybe_build_component_ref.  If the property is not found in

        (objc_finish_message_expr): Removed check to produce "readonly

        DECL_SOURCE_LOCATION of the new method to be the same as the one
        for the @synthesize.  Always use PROPERTY_IVAR_NAME as it is
        instead of trying to guess what it should be.  Removed use of

        and c_end_compound_statement.
        (objc_synthesize_setter): Mark 'klass' argument as unused.  Use
        PROPERTY_SETTER_NAME instead of trying to guess what it should be.

        instead of aborting, if the setter prototype does not have the
        expected argument.
        (objc_add_synthesize_declaration_for_property): New.
        (objc_add_synthesize_declaration): Removed ATTRIBUTE_UNUSED from
        all arguments.  Improved error message.  Filled in the rest of the

        (finish_class): Added explicit switch cases for
        CLASS_INTERFACE_TYPE, CATEGORY_INTERFACE_TYPE and
        PROTOCOL_INTERFACE_TYPE.  Added a default switch case which is
        gcc_unreachable.  Rewritten the processing of properties, in
        particular to not synthesize prototypes for getters and setters if
        they already exist and to install the getter and setter names into
        PROPERTY_GETTER_NAME and PROPERTY_SETTER_NAME.  Do not generate
        warnings about setter, getter and ivar property attributes.
        (objc_lookup_ivar): Removed support for properties.
        (objc_gimplify_property_ref): New.
