  Its probably worth mentioning also that most of the other processor
  models are dual-issue with very similar bundling rules. The 7100, 
  for example can issue 3 combinations: int-fp, fp-int, fp-branch. The
  7200 is similar, but also adds an int-int (with some restrictions)
  bundle type. So whichever of the 7xxx schedules we choose likely 
  won't cause death on other 7x000 processors. Still, the most common
  processor might be the best choice.
