Dear Huyite,

Your question, as stated, is too broad to answer.  It would help if your 
question were more specific; what is it that you want to accomplish?  
Are you interested in data flow within SSA virtual registers, or are you 
interested in data that is stored in memory (which is not in SSA form)?  
Are you analyzing code at the LLVM IR level or at the MachineInstr (MI) 
or MC level?  Are you wanting to print a data-flow graph, or are you 
developing an analysis that needs to understand a program's data flow in 
some way?

Without a more specific question, I cannot give a useful answer.
