llvm dev - Nov 2012 - [LLVMdev] Building a data flow graph from instructions in BasicBlock

Hi All,

I want to build a DFG from instructions in a basic block. I couldn't find a
function to find the depenencies between instructions. How can i do that ?

Look into ScheduleDAG.  It's a part of the scheduling infrastructure, 
but you can use it to build a dependency graph.

Thanks  Kryzstof,
I will look at it. Is there any class that I should look at it ? What about
Dataflow.h ? Since I am kind of new, I want to know which classes can help me
quicker.
