   Superscalars and instruction scheduling

   One quite frequently hears the claim that while good instruction   
   scheduling is a must for VLIWs and similar architectures, it is   
   not needed for superscalars. However, a superscalar processor only   
   has a limited window into the program, which may limit the   
   opportunities for exploiting ILP.   
      
   Googling for "superscalar instruction scheduling performance" gives   
   hits to fairly old papers. Does anyone know how important (if at all)   
   instruction scheduling is for getting good performance out of modern   
   superscalar processors?
