[Soot-list] Does soot preserve java bytecode offset information?

[Arzt, Steven]

Hi Shuyang,

You can try to look into Unit.getTags(). If there is a BytecodeOffsetTag,
that's what you're looking for.

Best regards,

Hello!

Recently my research requires me to find more detailed information on call
graphs of java programs. More specifically, in addition to knowing which
methods calls which methods (as shown by the call graph provided by soot), I
would like to know the java bytecode offset of each call site so that I can
distinguish some of the edges in the call graph. It seems to me that soot
does all of its analysis after translates java bytecode to its IR jimple and
it is not one to one mapping to the original java bytecode instructions. So
I wonder if soot preserve any java bytecode offset information at all? If
so, how can I access them? I was not able to find anything looking at the
soot source code but I could miss something.  

Thank you,
Shuyang Liu
