>>I don't know of any easy way to do this. You can't extract them in any programmable way, unless you write a plugin. Actually,let me tell u the reason i want to have the cfg and dfg information. I am trying to make a library for the binutils in which i want to use the code of gcc to optimize the loops and after having done that ,use my modifications to improve the performance even more. I am a bit of a novice in using the gcc and have had trouble in recent times understanding the code of gcc regarding tree-ssa-* (gimple dfg implementation). To do what i wanna do though, I am sure I will need the cfg and dfg information in some program structure so that i can use it for my lib. Now can someone suggest a way of approaching this. >>You can look in the dump files, but they are difficult to parse and will change as gcc changes. I know nothing about this. So can you elaborate this further and tell me how can i do this ? Thanks -- sandy
