Hi, I want to reorder the passes(RTL optimization passes) in the passes.c file. As far as I know, we can re-order only some passes. But how to make sure whether a pass can be reordered or not. I mean is there any predefined list of passes that can be re-ordered or something of that sort. Please help me out in this regard. Also any references that you suggest will be of great help. Thanks in advance Regards Pavan, Home: http://www.cse.iitb.ac.in/~pavankumar
