SootUp library

This is the home of the SootUp project. A complete overhaul of the good, old static analysis framework Soot.

What is SootUp

• Transforms JVM bytecode (and other inputs!) to the intermediate representation Jimple.
• Provides ClassHierarchy generation
• CallGraph generation with different algorithms/precisions
• Inter-procedural Data-flow Analysis with the IDE/IFDS framework enabled by Heros
• Applies simple transformations on retrieving a methods Body (see BodyInterceptor)
• Provides parsing and serialization of the Jimple IR.

Getting started

Documentation and usage examples are available on Examples. Check the Javadocs. Do you have questions? Feel free to start a Discussion.

SootUp improvements

(compared to its predecessor Soot.)

• New improved API (without Globals/Singletons)
• Fully-Parallelizable Architecture
• Enables lazy loading of classes (no interleaved loading of used/dependent classes anymore)
• Fail early strategy - input validation while constructing/building objects
• Up-to-Date (i.e. Java8!) Sourcecode Frontend (Beware: Cannot handle try-catch inputs, yet!)
• Full Java 21 Support for Bytecode
• Multiple Views (no single static Scene anymore)
• Immutable Jimple IR Objects and Graphs

Feel free to improve SootUp!
