Improving Thread-Modular Abstract Interpretation

Artifact for SAS '21 Paper: Improving Thread-Modular Abstract Interpretation
We give thread-modular non-relational value analyses as abstractions of a local trace semantics.
The semantics as well as the analyses are formulated by means of global invariants and side-effecting constraint systems.
We show that a generalization of the analysis provided by the static analyzer Goblint as well as a natural improvement of Antoine Miné’s approach can be obtained as instances of this general scheme.
We show that these two analyses are incomparable w.r.t. precision and provide a refinement which improves on both precision-wise.
We also report on a preliminary experimental comparison of the given analyses on a meaningful suite of benchmarks.
