In libobjc/: 2011-06-07 Nicola Pero <nicola.pero@meta-innovation.com> In libobjc/: 2011-06-07 Nicola Pero <nicola.pero@meta-innovation.com> Removed the Traditional Objective-C runtime public API. * Makefile.in (OBJC_DEPRECATED_H): Variable removed. (install-headers): Do not create the objc/deprecated directory and do not install the deprecated headers. (OBJC_H): Removed encoding.h and objc-api.h. * Object.m: Removed all methods with the exception of -class and -isEqual:. Updated includes. ([-class]): Use Modern API. * objc/Object.h: Do not include deprecated/Object.h. * objc/deprecated/Object.h: Removed. * linking.m (__objc_linking): Call [Object class] instead of [Object name]. * Protocol.m: Removed all methods with the exception of -isEqual:. Updated includes. * objc/Protocol.h: Do not include deprecated/Protocol.h. * objc/deprecated/Protocol.h: Removed. * objc/deprecated/struct_objc_symtab.h: Removed. * objc/deprecated/struct_objc_module.h: Removed. * objc/deprecated/struct_objc_ivar.h: Removed. * objc/deprecated/struct_objc_ivar_list.h: Removed. * objc/deprecated/struct_objc_method.h: Removed. * objc/deprecated/struct_objc_method_list.h: Removed. * objc/deprecated/struct_objc_protocol_list.h: Removed. * objc/deprecated/struct_objc_category.h: Removed. * objc/deprecated/MetaClass.h: Removed. * objc/deprecated/objc_msg_sendv.h: Removed. * objc/deprecated/README: Removed. * objc/deprecated/struct_objc_class.h: Removed. * objc/deprecated/struct_objc_protocol.h: Removed. * objc/deprecated/struct_objc_selector.h: Removed. * objc/encoding.h: Removed. * objc/message.h (struct objc_super): Removed the definition for the Traditional Objective-C runtime API. * objc/objc.h: Do not include objc/objc-decls.h. deprecated/struct_objc_selector.h, deprecated/MetaClass.h, deprecated/struct_objc_class.h, deprecated/struct_objc_protocol.h and deprecated/objc_msg_sendv.h. Uncommented new definition of Protocol *. * objc/objc-api.h: Removed. * objc/runtime.h: Updated comments. Removed check to detect concurrent usage of Traditional and Modern APIs. * objc-private/module-abi-8.h: Always define struct objc_class and struct objc_protocol. (struct objc_protocol_list): Changed type of 'list' argument from 'Protocol *' to 'struct objc_protocol *'. (class_get_instance_size): Added. * objc-private/protocols.h (__objc_protocols_add_protocol): Take a 'struct objc_protocol *' as argument, not a 'Protocol *'. * objc-private/runtime.h: Updated comments. * objc-private/selector.h (struct objc_selector, sel_eq): Added. * class.c: Include objc-private/selector.h. (objc_get_meta_class): Return a Class instead of a MetaClass. * encoding.c (method_get_next_argument): Removed. (method_get_first_argument): Removed. (method_get_nth_argument): Removed. * gc.c: Include objc/runtime.h instead of objc/encoding.h. Include objc-private/module-abi-8.h and ctype.h. * protocols.c (__objc_protocols_add_protocol): Take a 'struct objc_protocl *' as argument, not a 'Protocol *'. (class_addProtocol): Added casts to 'struct objc_protocol *' and 'Protocol *'. (class_copyProtocolList): Likewise. (protocol_conformsToProtocol): Likewise. (protocol_copyProtocolList): Likewise. * sarray.c: Include objc-private/module-abi-8.h. * sendmsg.c (method_get_next_argument): Removed. (method_get_first_argument): Removed.
