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 Github pages. Check the Javadocs. Do you have questions? Feel free to start a Discussion.
SootUp improvements
(compared to its predecessor Soot.)
- [x] New improved API (without Globals/Singletons)
- [x] Fully-Parallelizable Architecture
- [x] Enables lazy loading of classes (no interleaved loading of used/dependent classes anymore)
- [x] Fail early strategy - input validation while constructing/building objects
- [x] Up-to-Date (i.e. Java8!) Sourcecode Frontend (Beware: Cannot handle try-catch inputs, yet!)
- [x] Full Java 21 Support for Bytecode
- [x] Multiple Views (no single static Scene anymore)
- [x] Immutable Jimple IR Objects and Graphs
- [ ] Incremental Updates of Program Representation
