[Soot-list] Generate DFG and PDG using command line

[1530129650]

Hi  Admin       I'd like to use soot to generate CFG(control flow graph) , DFG(data flow graph) or PDG (Program dependence graph) based on IR in command line. However,  I just could generate  CFG using " java -cp sootclasses-trunk-jar-with-dependencies.jar  soot.tools.CFGViewer --soot-classpath .;"%JAVA_HOME%"\jre\lib\rt.jar --graph=BriefBlockGraph  ****". The node in generated CFG is an instruction rather than a variable or operator as following , which is I  want to get. I look through the soot tutorial, issue,  and google again and again. However, I fail to generate DFG and PDF.  Could you please help me to generate CFG, DFG or PDG based on IR in command line. Thanks  Jing

Hi Jing,

The CFGViewer produces a dump of the control-flow graph, which is the basic Soot intermediate representation (namely, three-address Jimple code). I'm not sure exactly which graphs you are hoping to see, but you would have to write more code to have graphs that have nodes that are variables rather than statements. Some of the statements are an operator, like the one in your example, temp$7 = x1 + 1. Basically I don't really understand what you are trying to get.
