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>John Criswell<br><br><br>On 6/16/16 9:15 AM, huyite via llvm-dev wrote:<span style='font-size:12.0pt'><o:p></o:p></span></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal>Dear all,<o:p></o:p></p><p class=MsoNormal> Please help me to generate DFG(Data flow graph) in LLVM.<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal><span lang=VI>Best regards,</span><o:p></o:p></p><p class=MsoNormal><span lang=VI> Huy</span><o:p></o:p></p><p class=MsoNormal><i><span lang=VI> </span></i><o:p></o:p></p><p class=MsoNormal><i><span lang=VI>Mobile: </span>+84942976091</i><o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><br><br><br><o:p></o:p></span></p><pre>_______________________________________________<o:p></o:p></pre><pre>LLVM Developers mailing list<o:p></o:p></pre><pre><a href="mailto:llvm-dev@lists.llvm.org">llvm-dev@lists.llvm.org</a><o:p></o:p></pre><pre><a href="http://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-dev">http://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-dev</a><o:p></o:p></pre></blockquote><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p> </o:p></span></p><p><o:p> </o:p></p><pre>-- <o:p></o:p></pre><pre>John Criswell<o:p></o:p></pre><pre>Assistant Professor<o:p></o:p></pre><pre>Department of Computer Science, University of Rochester<o:p></o:p></pre><pre><a href="http://www.cs.rochester.edu/u/criswell">http://www.cs.rochester.edu/u/criswell</a><o:p></o:p></pre></div></body></html>
