Summary: This class is unnecessary. Its comment indicated that it was a compile error to allocate an instance of a class that inherits from RefCountedBaseVPTR on the stack. This may have been true at one point, but it's not today. Moreover you really do not want to allocate *any* refcounted object on the stack, vptrs or not, so if we did have a way to prevent these objects from being stack-allocated, we'd want to apply it to regular RefCountedBase too, obviating the need for a separate RefCountedBaseVPTR class. It seems that the main way RefCountedBaseVPTR provides safety is by making its subclass's destructor virtual. This may have been helpful at one point, but these days clang will emit an error if you define a class with virtual functions that inherits from RefCountedBase but doesn't have a virtual destructor.

//===----------------------------------------------------------------------===// // 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.llvm.org/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
