Warn in cases where one has provided redundant protocol qualification that might be a typo for a specialization, e.g., NSArray<NSObject>, which is pointless (NSArray declares that it conforms to NSObject) and is likely to be a typo for NSArray<NSObject *>, i.e., an array of NSObject pointers. This warning is very narrow, only applying when the base type being qualified is parameterized, has the same number of parameters as their are protocols listed, all of the names can also refer to types (including Objective-C class types, of course), and at least one of those types is an Objective-C class (making this a typo for a missing '*'). The limitations are partly for performance reasons (we don't want to do redundant name lookup unless we really need to), and because we want the warning to apply in very limited cases to limit false positives.

//===----------------------------------------------------------------------===// // C Language Family Front-end //===----------------------------------------------------------------------===// Welcome to Clang. This is a compiler front-end for the C family of languages (C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM compiler infrastructure project. Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer. If you're interested in more (including how to build Clang) it is best to read the relevant web sites. Here are some pointers: Information on Clang: http://clang.llvm.org/ Building and using Clang: http://clang.llvm.org/get_started.html Clang Static Analyzer: http://clang-analyzer.llvm.org/ Information on the LLVM project: http://llvm.org/ If you have questions or comments about Clang, a great place to discuss them is on the Clang development mailing list: http://lists.cs.uiuc.edu/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
