Added a new attribute, objc_root_class, which informs the compiler when a root class is intentionally declared. The warning this inhibits, -Wobjc-root-class, is opt-in for now. However, all clang unit tests that would trigger the warning have been updated to use -Wno-objc-root-class. <rdar://problem/7446698> llvm-svn: 154187 2012-04-07 02:12:22 +08:00			`// RUN: %clang_cc1 -verify -Wno-objc-root-class %s`
Patch to implemented objective-c's dynamic object pointer qualified with the protocol list (id<P,...> types). llvm-svn: 45121 2007-12-18 05:03:50 +08:00

Contains the following (related to problems found while investigting <rdar://problem/6497631> Message lookup is sometimes different than gcc's). - Implement instance/class overloading in ObjCContainerDecl (removing a FIXME). This involved hacking NamedDecl::declarationReplaces(), which took awhile to figure out (didn't realize replace was the default). - Changed Sema::ActOnInstanceMessage() to remove redundant warnings when dealing with protocols. For now, I've omitted the "protocol" term in the diagnostic. It simplifies the code flow and wan't always 100% accurate (e.g. "Foo<Prot>" looks in the class interface, not just the protocol). - Changed several test cases to jive with the above changes. llvm-svn: 65292 2009-02-23 03:35:57 +08:00			`- (void)IMeth { [(id<P>)self Meth]; } // expected-warning {{method '-Meth' not found (return type defaults to 'id')}}`
