//===----------------------------------------------------------------------===// // 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/

The coverage implementation marks functions which won't be emitted as 'deferred', so that it can emit empty coverage regions for them later (once their linkages are known). Functions in dependent contexts are an exception: if there isn't a full instantiation of a function, it shouldn't be marked 'deferred'. We've been breaking that rule without much consequence because we just ended up with useless, extra, empty coverage mappings. With PR32679, this behavior finally caused a crash, because clang marked a partial template specialization as 'deferred', causing the MS mangler to choke in its delayed-template-parsing mode: error: cannot mangle this template type parameter type yet (http://bugs.llvm.org/show_bug.cgi?id=32679) Fix this by checking if a decl's context is a dependent context before marking it 'deferred'. Based on a patch by Adam Folwarczny! Differential Revision: https://reviews.llvm.org/D32144 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@300723 91177308-0d34-0410-b5e6-96231b3b80d8
