   As long as you are looking at argument labels it would possibly be a good   
   idea to see if you can give (some or all of) the preserved registers (and   
   memory locations?) labels too.   It makes no sense to preserve a register   
   also used as an argument, only to have to store it again locally so you get   
   a label for and by it can retrieve it multiple times in your procedure.   
      
   Either that, or just store it locally and restore it yourself (using a MOV,   
   not a POP :-) ) at the end of the procedure.
