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 -fsyntax-only -verify -Wno-objc-root-class %s`
"This patch uses the new ObjCImplDecl class to merge Sema::ImplMethodsVsClassMethods and Sema::ImplCategoryMethodsVsIntfMethods methods. And now, when clang check a class implementation to find unimplemented methods, it also checks all methods from the class extensions (unnamed categories). There is also a test case to check this warning. This patch contains also a minor update for ObjCImplDecl . getNameAsCString and getNameAsString now returns an empty string instead of crashing for unnamed categories."

Change 'method X in protocol not implemented' warning to include the name of the protocol. This removes an extra "note:", which wasn't really all that more useful and overall reduces the diagnostic spew for this case. llvm-svn: 197207 2013-12-13 13:58:51 +08:00			`@interface MyClass`

After numerous requests, have Objective-C 'method declared here' notes mention the actual method. This looks better within an IDE, where text isn't always regurgitated in the presentation of a warning. Fixes radar 10914035. llvm-svn: 151579 2012-02-28 06:55:11 +08:00			`- (void)Pmeth1; // expected-note {{method 'Pmeth1' declared here}}`

Split "incomplete implementation" warnings for ObjC into separate warnings. Previously all unimplemented methods for a class were grouped under a single warning, with all the unimplemented methods mentioned as notes. Based on feedback from users, most users would like a separate warning for each method, with a note pointing back to the original method declaration. Implements <rdar://problem/13350414> llvm-svn: 178097 2013-03-27 08:02:21 +08:00			`- (void)meth2; // expected-note {{method 'meth2' declared here}}`
