| Taking out the Toxic Trash: Recovering Precision in Mixed Flow-Sensitive Static Analyses | PLDI 2025 | 2025-06-16 |
Proposes three concrete fixes — narrowing per origin, reluctant widening, and abstract garbage collection — that decouple global updates via an update rules… | ||
| Correctness Witnesses for Concurrent Programs: Bridging the Semantic Divide with Ghosts | VMCAI 2025 | 2025-01-20 |
Proposes a machine-readable ghost witness format that instruments programs with ghost variables and statements so a validator checks witness validity by… | ||
| C-2PO: A Weakly Relational Pointer Domain: “These Are Not the Memory Cells You Are(…) | NSAD 2024 | 2024-10-22 |
A new weakly relational pointer domain for C, C-2PO, tracks must-equalities and -disequalities between pointer expressions, models address arithmetic confined… | ||
| When to Stop Going Down the Rabbit Hole: Taming Context-Sensitivity on the Fly | SOAP 2024 | 2024-06-25 |
Provides a framework and three generic lifters implemented as decorators around Goblint and evaluated on SV-COMP recursive benchmarks. Limits contexts on the… | ||
| Correctness Witness Validation by Abstract Interpretation | VMCAI 2024 | 2024-01-15 |
Introduces a concrete unassume operator that injects witness invariants into an abstract interpreter to relax state information deliberately, implemented in… | ||
| Octagons Revisited - Elegant Proofs and Simplified Algorithms | SAS 2023 | 2023-10-22 |
Provides simplified cubic time closure algorithms for Octagon abstract relations over rationals and integers that avoid introducing auxiliary negation… | ||
| Improving Thread-Modular Abstract Interpretation | SPLASH 2022 | 2022-12-05 |
Presents a thread‑modular framework that formalizes analyses as side-effecting constraint systems with a new local trace semantics, proves soundness of… | ||
| Improving Thread-Modular Abstract Interpretation | SAS 2021 | 2021-10-17 |
Formalizes thread-modular non-relational value analyses with a new local trace semantics and a side-effecting constraint-system framework, casts Goblint’s… | ||
| Counterexample- and Simulation-Guided Floating-Point Loop Invariant Synthesis | SAS 2020 | 2020-11-18 |
Method synthesizes floating-point loop invariants by combining counterexample-guided synthesis with random simulation and a noisy polynomial fit for candidate… | ||
| Stratified Guarded First-Order Transition Systems | SAS 2020 | 2020-11-18 |
Defines a class of first-order transition systems that is stratified and strictly guarded, shows weakest-precondition fixpoint iteration eliminates… | ||
