You'd obviously need to worry about dependencies between passes.Look at passes.c a.k.a the pass manager. http://gcc.gnu.org/onlinedocs/gccint/Pass-manager.html > 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. info gccint gives you a list of passes and the order in which they are run. It covers the order for the tree passes as well as the RTL passes. ~r > Please help me. > > Thanks in advance > Pavan, > Home: http://www.cse.iitb.ac.in/~pavankumar > > > > > > -- Ramana Radhakrishnan <ramana.radhakrishnan@xxxxxxxxxx> Codito Technologies Pvt.
