<br>
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?<br>
<br>
Without a more specific question, I cannot give a useful answer.<br>
<br>
Regards,<br>
<br>
