Hi all, Currently I am doing some work on CIL. I would like to obtain the conditional result (true/false) in the DOT file generated by CIL. Therefore, I modified the code in ext/cfg.ml. let d_cfgedge (src) () (dest) = match src.skind with | If (_, tb, fb, _) -> (if (List.mem dest tb.bstmts) then dprintf "%a -> %a [label=\"true\"]" d_cfgnodename src d_cfgnodename dest else if (List.mem dest fb.bstmts) then dprintf "%a -> %a [label=\"false\"]" d_cfgnodename src d_cfgnodename dest else dprintf "%a -> %a [label=\"true$\"]"(*true likely, note that no false likely!!!*) d_cfgnodename src d_cfgnodename dest); | _ -> dprintf "%a -> %a" d_cfgnodename src d_cfgnodename dest However, I am wondering whether my solution is correct becuase there is no related document explaining this issue. In particularly, in my real cases, I found the highlighted case is also hit. I am also wondering whether there are other cases that I don't consider here. Look forward to your reply. Any concern or feedback would be greatly appreciated. Thanks, Haihao
