[Soot-list] counting number of lines in jimple

[Eric Bodden]

Hi there.

I am afraid my answer won't be very helpful... I just wanted to let
you know that I am not aware of any tags that would tell you Jimple
line numbers. There may be some, but I am not sure. Actually I think
that it would make little sense ot have such tags because the line
numbers change whenever modifying the Jimple, which happens quite
often.
