     I have an messy notes about what I've done but it's too
     embarassed to show. :) . Moreove, I don't have enough time...

     Yes. I expect some performance gain after removals.I did it quite
     a while ago when I SIMDize ODE.Recently, some one post on the
     list about this so I publish my patch.

     To anyone use VTune, please do experiments and publish the results.

     Happy coding!
