[Soot-list] How to map line number to units

[Steven Arzt]

Hi,

the line numbers are available through the tags associated with the
respective units. There are multiple types of tags, some only have the
source line number, others also the column in the source file. From
bytecode, you will only get line numbers, from source code, you can also get
columns. Try Unit.getTags() (inherited from the Host class).

However, there are some things to keep in mind: Soot's front-end for Java
source code is not up to date. This means that you are unlikely to be able
to parse Java 7-style source code. Java 6 should be fine, though. Developing
a new source front-end is a major undertaking we need to do at some point.
If you use the bytecode front-end, you should be on the safe side.

Best regards,
  Steven

Subject: [Soot-list] How to map line number to units

Hi,

I'm trying to produce a Data Flow Analysis (intra-procedural) for Android
applications. The aim of the analysis is to help generate constraints for
the application using line numbers in the original source code as variables.
I've been able to generate the Data Flow Analysis for Java programs. I've
the following questions:

1. Is it possible to map the units in the graphs to the source code line
numbers ?

2. Does Soot produce a list of Dominant nodes ?

Thank you.
