Swift needs Clang to link with. The linker patch breaks linking when using Swift with a GCC‐based standard environment. Similarly, the internal Clang headers in the resource directory are coupled to the corresponding version of Clang. The resource root patch caused Swift’s Clang to use the resource directory from the version of Clang used in the build environment, which is only compatible if the versions match. Instead, hard‐code the Clang path in the patches and wrappers.
