would it not more or less be the same thing if you used -finstrument-functions
then and provide a stub __cyg_profile_func_enter/exit initialized to an empty
function until you replace it during tracing. This does give you an overhead
when you are not tracing - but it would make the tracer implementation quite
generic.
