  10. I'm looking for statistics about what proportion of instructions use as
  11. operands the results of immediately preceding instructions, preferably for
  12. optimally reordered code and subdivided into loads and computes.  I want to
  13. compute the benefit of various forms of register forwarding.
  14.  
  15. Does anyone have these figures, or references to where I can find them ?
  16.  
  17. Many thanks,
