The source file is used to anchor the destructor of format_error. When format is moved from experimental to stable this code would move to the dylib. One issue with code in the dylib is that it can't be used in constexpr context. There is a proposal to make format work during constant evaluation P2758 Emitting messages at compile time This paper has initially been received favourable by EWG. Therefore move the code to the header. This also avoids possible availability issues on Mac back deployment targets. Note it is expected that format will no longer be experimental with the next LLVM release. Reviewed By: ldionne, #libc Differential Revision: https://reviews.llvm.org/D150073
