Summary: Fixes PR41677 Consider: template <typename LHS, typename RHS> constexpr bool is_same_v = false; template <typename T> constexpr bool is_same_v<T, T> = true; template constexpr bool is_same_v<int, int>; Before this change, when emitting debug info for the `is_same_v<int, int>` global variable, clang would crash because it would try to use the template parameter list from the partial specialization to give parameter names to template arguments. This doesn't work in general, since a partial specialization can have fewer arguments than the primary template. Therefore, always use the primary template. Hypothetically we could try to use the parameter names from the partial specialization when possible, but it's not clear this really helps debugging in practice.

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