Hi, Does the order of optimizations effects the generated code ? If i want to change the order of optimizations then how it would it be possible ? In which part of the gcc source code about the order of optimization passess are defined. I want to know, what are the optimizations can be done on the RTL level. Is there any way to control the order of those optimizations. In which source file of gcc they are defined. Please help me. Thanks in advance Pavan, Home: http://www.cse.iitb.ac.in/~pavankumar
