[Soot-list] How to Get a Call Graph Using On-The-Fly Analysis

[杨鹏]

Hello, 


The information that you provided is really helpful in building the on-the-fly call graph. Thanks for your reply.


Then, I still have two more questions about the call graph:


1. What's the precision about the on-the-fly call graph, is it flow-sensitive? or context-sensitive?
2. If I want to know how the call graph is built in a on-the-fly way, what can I do? I mean, is there any paper about it or I should read relevant source codes in soot? 


Thanks.

Hello,

There is a nice summary of all options here: http://www.sable.mcgill.ca/soot/tutorial/usage/,
and phase-specific options here: http://www.sable.mcgill.ca/soot/tutorial/phase/phase.html

On-the-fly call graph is, for example, supported by Spark. You can enable Spark using the option "-p cg.spark enabled:true".

If you want to examine the call graph, then instead of using these options on the command-line, what you can do is pass these options (as a string) to soot.Main.main(), after which you should be able to access the constructed call graph using Scene.v().getCallGraph().

Hope this helps.

Regards,
Rohan

Hello,


Thanks for your suggestion. However, it's a little difficult to find the relevant options in soot main without a guideline. May I get more details about it or where can I get a guideline about it? Thanks again for your help.
