[Soot-list] Map from source line numbers to class file line numbers

Hi Manur.

I am not sure what you mean by "line number 20 in the class file". Class files have no line numbers. Do you mean the instruction count maybe? If so, if I remember correctly then there is a different kind of tag that Soot uses to keep track of those.

Best wishes,
Eric

When I am taking the line number tag, I am still getting ’10’ even though I am giving my class file as input to Soot, i.e., the line number of the variable in the java file. Is there some way through which I can get ’20’?
