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

Objective-C [qoi]: privide typo correction for selectors in addition of receiver having static type, but also when receiver has dynamic type (of 'id' variety) as well as when receiver is of 'Class' type vareity. // rdar://7853549 llvm-svn: 184195 2013-06-18 23:31:36 +08:00			`- (void)IMeth { [(id<P>)self Meth]; } // expected-warning {{instance method '-Meth' not found (return type defaults to 'id'); did you mean '-IMeth'?}}`
