   Colouring hurts ILP extraction for both superscalar VLIW and EPIC   
   processors. Even if the ILP is not exposed at the architectural level,   
   compilers schedule operations to help the processor to extract it at   
   execution time.   
      
   If register allocation with coloring methods are used, the ILP of the   
   generated code would not be easily extracted by the processor at   
   execution time. Dynamic renaming is limited in practice (since the   
   window od instructions is limited).
