Hi, I used the -fdump-tree-cfg to generate basic blocks, but what I really need is the data flow inside these basic blocks. I have read the debugging options, but I didn't find anything. Is there any command so I can use to generate the dfgs or someone implemented any tool that I can use? I'll be really gratefull. P.S: I just want to get the basic blocks generated by the -fdump-tree-cfg and see the data flow, but if someone has a tool that generates basic blocks and data flow using other commands it will be usefull too. Thanks Monica
