[LLVMdev] Data Dependency graph

I too need to generate a data dependency graph. Have not been able to
generate so far. I have tried using Dragon tool of Open64, but it is
specific to arrays only. I am looking for some detailed dependency graph,
that would show me the true, anti and output dependencies. 
I have played around with Rose compiler and its associated graphic tools,
but again, they are too clustered and cannot see any such explicit
Any suggestions ? 
Thank you.
