Re: What are the best gcc optimization options for Pentium 200 MMX

    A couple of reasons, but the two main ones are:

    * They are still under development

    * They won't do what you expect (for example, the pentium optimizations
      often produce faster code on a PIII then the i686 optimizations)

    * They *have* been known to generate bad code, owing to being under
      constant development.

    * And your binaries won't necessarily be portable between 
      manufacturers (AMD vs Intel), or performance may suffer.
