Questions & Answers
I am reading the soot source code and got confused with the following method 'simpleSources' in 'soot.jimple.spark.pag.PAG.java'. This method should return a set, but I am just wondering what are the elements inside this set?
In java 6 we have the method 'getAnnotation(Class annotationClass)' to get annotation of a particular class or method. Anybody knows the equivalent way of getting method/class annotations in Soot?
Is there a way to traverse the AST of Java with SOOT?
Does Soot support generics? I need to construct Jimple code which creates an instance of a generic class.
Does anyone know how to use soot to get the return value?
Is there an implementation for escape analysis? I found the interface (soot.EscapeAnalysis), but couldn't find any implementation in soot library.
Can you tell me please what king of Stmt is "lengthof x" in Jimple? If I have the statement: "n = x.length" (in Java; x is a Vector), then soot translates that in Jimple so: $i0 = lengthof x n = (double) $i0 and I don't know how to handle "lengthof x" - I saw it isn't an InvokeStmt.
I've recently started to use Soot and Paddle for my master thesis work. I noticed that Paddle takes too much time to analyse Soot results and I presume it analyses Java library as well. Is it possible to speed up the analysis by configuring Soot or Paddle somehow to exclude analysis of Java libraries?
I need to convert Jimple statements to Java source code. Let me explain what I am trying to do - I am using the Indus slicer to produce program slices of Java programs. The slices come out in Jimple or Class files. I need to map or convert them into Java source code. Any ideas how to achieve this?
I want to use Soot for outlining certain code fragments into new methods. However, I can't find any indication that Soot has support for deciding whether or not a code fragment can be outlined. Is this true, or did I just not look hard enough?
Are there any open source or previous works available for memory bound analysis using Soot ?
I was wondering if one can load a class from a .jar file or load a class by specifying the file containing the class? Loading a class by specifying the name is not very flexible. If not, what and where should I modify?
Is there any way to force the output to be in both jimple and bytecode at the same time? Sometimes, I'll get the bytecode wrong, and just by looking at the Jimple I can figure out what is going on. But then I have to run Soot again!
Is there an easy way of detecting whether a goto statement is a break or continue statement in Soot? Particularily in Jimple.
