The benchmark is on the release page as a single .zip file. It includes the SMT-LIB files and various scripts to produce the paper data.

The latest tool is on the soot-parse-smtlib branch. To use it, please modify the src/main/kotlin/Driver.kt to add the .jar file path in it. For the runOnAllProjects flag, every sub-folder under the path should contain a .jar file.
