    Abstract
    Counterexample-guided abstraction refinement is a property-directed approach for the automatic construction of an abstract model for a given system. The approach learns information from infeasible error paths in order to refine the abstract model. We address the problem of selecting which information to learn from a given infeasible error path. In previous work, we presented a method that enables refinement selection by extracting a set of sliced prefixes from a given infeasible error path, each of which represents a different reason for infeasibility of the error path and thus, a possible way to refine the abstract model. In this work, we (1) define and investigate several promising heuristics for selecting an appropriate precision for refinement, and (2) propose a new combination of a value analysis and a predicate analysis that does not only find out which information to learn from an infeasible error path, but automatically decides which analysis should be preferred for a refinement. These contributions allow a more systematic refinement strategy for CEGAR-based analyses. We evaluated the idea on software verification. We provide an implementation of the new concepts in the verification framework CPAchecker and make it publicly available. In a thorough experimental study, we show that refinement selection often avoids state-space explosion where existing approaches diverge, and that it can be even more powerful if applied on a higher level, where it decides which analysis of a combination should be favored for a refinement.

    Abstract
    Proper benchmarking and resource measurement is an important topic, because benchmarking is a widely-used method for the comparative evaluation of tools and algorithms in many research areas. It is essential for researchers, tool developers, and users, as well as for competitions. We formulate a set of requirements that are indispensable for reproducible benchmarking and reliable resource measurement of automatic solvers, verifiers, and similar tools, and discuss limitations of existing methods and benchmarking tools. Fulfilling these requirements in a benchmarking framework is complex and can (on Linux) currently only be done by using the cgroups feature of the kernel. We provide BenchExec, a ready-to-use, tool-independent, and free implementation of a benchmarking framework that fulfills all presented requirements, making reproducible benchmarking and reliable resource measurement easy. Our framework is able to work with a wide range of different tools and has proven its reliability and usefulness in the International Competition on Software Verification.

    Abstract
    k-Induction is a promising technique to extend bounded model checking from falsification to verification. In software verification, k-induction works only if auxiliary invariants are used to strengthen the induction hypothesis. The problem that we address is to generate such invariants (1) automatically without user-interaction, (2) efficiently such that little verification time is spent on the invariant generation, and (3) that are sufficiently strong for a k-induction proof. We boost the k-induction approach to significantly increase effectiveness and efficiency in the following way: We start in parallel to k-induction a data-flow-based invariant generator that supports dynamic precision adjustment and refine the precision of the invariant generator continuously during the analysis, such that the invariants become increasingly stronger. The k-induction engine is extended such that the invariants from the invariant generator are injected in each iteration to strengthen the hypothesis. The new method solves the above-mentioned problem because it (1) automatically chooses an invariant by step-wise refinement, (2) starts always with a lightweight invariant generation that is computationally inexpensive, and (3) refines the invariant precision more and more to inject stronger and stronger invariants into the induction system. We present and evaluate an implementation of our approach, as well as all other existing approaches, in the open-source verification-framework CPAchecker. Our experiments show that combining k-induction with continuously-refined invariants significantly increases effectiveness and efficiency, and outperforms all existing implementations of k-induction-based verification of C programs in terms of successful results.

    Abstract
    Automatic software verification relies on constructing, for a given program, an abstract model that is (1) abstract enough to avoid state-space explosion and (2) precise enough to reason about the specification. Counterexample-guided abstraction refinement is a standard technique that suggests to extract information from infeasible error paths, in order to refine the abstract model if it is too imprecise. Existing approaches -including our previous work- do not choose the refinement for a given path systematically. We present a method that generates alternative refinements and allows to systematically choose a suited one. The method takes as input one given infeasible error path and applies a slicing technique to obtain a set of new error paths that are more abstract than the original error path but still infeasible, each for a different reason. The (more abstract) constraints of the new paths can be passed to a standard refinement procedure, in order to obtain a set of possible refinements, one for each new path. Our technique is completely independent from the abstract domain that is used in the program analysis, and does not rely on a certain proof technique, such as SMT solving. We implemented the new algorithm in the verification framework CPAchecker and made our extension publicly available. The experimental evaluation of our technique indicates that there is a wide range of possibilities on how to refine the abstract model for a given error path, and we demonstrate that the choice of which refinement to apply to the abstract model has a significant impact on the verification effectiveness and efficiency.

    Abstract
    We submit to SV-COMP'15 the software-verification framework CPAchecker. The submitted configuration is a combination of seven different analyses, based on explicit-value analysis, k-induction, predicate analysis, and concrete memory graphs. These analyses use concepts such as CEGAR, lazy abstraction, interpolation, adjustable-block encoding, bounded model checking, invariant generation, and block-abstraction memoization. Found counterexamples are cross-checked by a bit-precise analysis. The combination of several different analyses copes well with the diversity of the verification tasks in SV-COMP.
