This reads a little oddly. How about:
Note that GCC can completely remove the bodies of functions that are not
needed -- for instance if they are inlined everywhere. Such functions
are marked with @samp{-}, which can be confusing. Use the
@option{-fkeep-inline-functions} and @option{-fkeep-static-functions}
options to retain these functions and allow gcov to properly show their
@var{execution_count}.
Ok with that (or something approximating it).
