To reorder BBs I use the following procedure: 1. cfg_layout_initialize (0); 2. FOR_EACH_BB(bb) set bb->rbi->next properly for each, so they all create a chain of BB 3. cfg_layout_finalize(); Does this reorder the insn chain? If not, how do I reorder it? Or where do I look for how it's done? G. -- Gregory B. Prokopski <[EMAIL PROTECTED]> Sable Research Group http://www.sable.mcgill.ca Montreal, Quebec, Canada
