Loopfrog experiments

Benchmarks

We use two benchmark sets for regression testing and to demonstrate the effectiveness of Loopfrog. From the original sources, we compiled our own suites, to simplify the benchmarking process. We only added labels to mark specific assertions and adjusted include paths, as we flattened the hierarchy. Our test scripts are included.

  • Benchmark Set A: This set is described in
    Ku K., Hart T.E., Chechik M., Lie D.: A buffer overflow benchmark for software model checkers. ASE 2007: 389-392.

  • Benchmark Set B: This set is described in
    Zitser M., Lippmann R., Leek T.: Testing Static Analysis Tools Using Exploitable Buffer Overflows From Open Source Code. FSE 2004.

The results of our evaluation of loopfrog on the benchmark sets are published in [1]

Evaluation on Large-Scale Software

We also evaluate Loopfrog on a benchmark suite of large-scale open-source software. The goto-models for these benchmarks may be obtained from the goto-cc webpage. We present statistics obtained on an 8-core Intel Xeon 3 GHz machine with 16 GB of RAM. We limited the runtime to four hours and the memory to 4 GB per process.

Note: The tests include assertions over strings and array/buffer bounds. Assertions are based on the data from the pointer-analysis; unnecessary assertions were not added (and are not included in the total count).

We evaluated Loopfrog in different configurations. For the results, please chose one of the following categories:
