[Soot-list] Howto generate a CallGraph?

[bq chan]

I tried the code you provided, but  it seemed something wrong.

It ran heavily, slowly and giving message repeatly:

    GC Warning: Repeated allocation of very large block (appr. size *****):
        May lead to memory leak and poor performance.

Could u plz help me. Thanks!


As follows:

[cbq at localhost src]$ java CGMain -w CallGraphs
Soot started on Mon May 05 21:12:45 GMT+08:00 2008
GC Warning: Repeated allocation of very large block (appr. size 331776):
        May lead to memory leak and poor performance.
No main class given. Inferred 'CallGraphs' as main class.
[Call Graph] For information on where the call graph may be incomplete, use
the verbose option to the cg phase.
GC Warning: Repeated allocation of very large block (appr. size 540672):
        May lead to memory leak and poor performance.

Core code:

     public static void main(String[] args)
  {

        PackManager.v().getPack("wjtp").add(new
Transform("wjtp.mycgTransformer", CGTransformer.v()));
        soot.Main.main(args);
    }

     protected void internalTransform ( String phaseName, Map options)
            {
                    CallGraph cg =Scene.v().getCallGraph();
                    System.out.println("Size:"+cg.size());



            }
