llvm dev - Dec 2008 - [LLVMdev] Data Dependency graph

Hi,

I need to generate a data dependancy graph. Is there any functionality
available in LLVM which can help me? Or if anyone can point to the correct
place?

Thanks

There are many different forms of dependency graph, do you mean for  
loop dependencies, load and store dependencies, def/use dependencies,  
etc?

Hi

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
dependencies. 
Any suggestions ? 
Thank you.
