Synopsis: Suboptimal schedule following unroll of "reversed" loops in gcc

State-Changed-Why:
    This is a report against a version of gcc that is now
    rather old. Can you say anything about whether the problem
    persists with newer versions of gcc, such as 3.2.2 or
    the version presently in CVS?
    
    Thanks
      Wolfgang
