I don't know much about compilation and flow information. Actually, I work with integrated systems, specifically reconfigurable architecture. And what I need is to get a c written application and extract its data flow so I can analyze and decide what is gonna run in my architecture. I don't have any demands about what commands to use, I just found the -fdump, and supposed that it would be useful. I have already looked for free tools to use, but what I have found isn't appropriated for several reasons, for example: the code is optimized according to the processor used, and very often the processor isn't an open project, so, the graph isn't useful because is to particular for that processor. So, if you know any tool that generates these data flows or if I can extract this through gcc commands it is enough to me. Thanks for your attention. Monica
