Silvius, If you want to persue this, you should go back and look at my patches for subreg level dataflow and start hacking from there. It is not a big step to start from that and modify it for bits. If you start from that, it is most likely not much more than a few days work for the analysis part. However, hacking combine could be a life long effort!
All of this code got removed because it's only client was the old ra. Kenny
