That sounds doable and would indeed be a good solution.
I'll investigate this route more.

Yes, that would be a definite plus!
However, my request still stands for more comments in this function.
Vladimir, could you take care of that?

Also, it seems that it might help to break the function up in three
smaller functions:
   - the forward dynamic programming pass generating states
     and finding states with minimal cost (about 150 lines)
   - the backward pass adding nops and templates (about 125 lines)
   - the Itanium-1 specific stuff (about 75 lines)
