   Register Spilling Heuristic ?

   Hello all,   
      
   I am trying to implement Briggs register allocator. While doing that i   
   came across documents indicating how to choose nodes for spilling. The   
   documents says to avoid choosing nodes that are the tiny live ranges   
   resulting from the fetches of previously spilled registers.   
      
   What does this mean? Does it mean that the definition points of a   
   spilled live range that have been stored to memory in a previous   
   spilling iteration do not need to be stored again and the definition   
   points of a spilled live range that begin with spill loads that were   
   inserted in a previous spilling iteration do not need to be stored.   
      
   Any help is appreciated.   
      
   Regards,   
   Shafi.
