Hi Soumya,
Here is some information on the IR:
http://wala.sourceforge.net/wiki/index.php/UserGuide:IR
And if you'd like to map the slice back to source code, there is some info on that here:
http://wala.sourceforge.net/wiki/index.php/UserGuide:MappingToSourceCode
Let us know if you have other questions.
Best,
Manu

Hi ,
I'm a starter in WALA . I'm trying to create a slice of a program using SlicerTest.java . I get the following output in IR . How do I interpret it ? Is there any help available regarding the IR representation ? Below is the IR of the slice. Please give me pointers on how to make sense out the IR.
