>
> Since this file comes from OpenSSL, and since it is a perl file
> which generates a .S file, it may not be the best choice to
> make too many code changes to such files, unless absolutely
> necessary.

> Second reason is that, at least as far as the objtool --mcount
> functionality is concerned, we do not have to run objtool on
> that file because that file does not have any calls to _mcount.
