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?
Uh, what kind of dataflow information are you looking for, exactly. At the tree level, we use SSA form, where most of the standard dataflow information (use def chains, def use chains, reaching definitions) is explicitly in the IR, not in some on the side structure that you can dump. You can dump the IR for any pass using -fdump-tree-<pass>-all
