In order to actually trace the functions,
you will need to link a separate runtime library of your choice,
such as Clang's [XRay Runtime Library](https://www.llvm.org/docs/XRay.html#xray-runtime-library).
On targets where such a runtime is not available but instrumentation is supported, you must supply and link your own runtime library.
