Verification Witnesses from Verification Tools (SV-COMP 2021)

Verification Witnesses

This file describes the contents of an archive of the 10th Competition on Software Verification (SV-COMP 2021).
https://sv-comp.sosy-lab.org/2021/

The competition was run by Dirk Beyer, LMU Munich, Germany.

Contents

• LICENSE.txt: specifies the license
• README.txt: this file
• witnessFileByHash/: This directory contains verification witnesses. Each verification witness in this directory is stored in a file whose name is the SHA2 256-bit hash of its contents followed by the filename extension .graphml. The format of each verification witness is described on the format web page: https://github.com/sosy-lab/sv-witnesses/ A verification witness contains also metadata in order to relate it to the verification task for which it was produced.
• witnessInfoByHash/: This directory contains for each verification witness in directory witnessFileByHash/ a record in JSON format (also using the SHA2 256-bit hash of the witness as filename, with .json as filename extension) that contains the meta data.
• witnessListByProgramHashJSON/: For convenient access to all verification witnesses for a certain program, this directory represents a function that maps each program (via its SHA2256-bit hash) to a set of verification witnesses (JSON records for verification witnesses as described above) that the verification tools have produced for that program. For each program for which verification witnesses exist, the directory contains a JSON file (using the SHA2 256-bit hash of the program as filename, with .json as filename extension) that contains all JSON records for verification witnesses for that program.

The data structure is described in the following article:
