In this paper we introduce a novel method for improving static analysis of real code by using dynamic analysis. We have implemented our technique to enhance the Infer static analyzer [6] for Erlang by supplementing its analysis with data obtained by ...

We investigate a modification of the classical Bounded Model Checking (BMC) procedure that does not handle loops through unrolling but via modifications to the control flow graph (CFG). A portion of the CFG representing a loop is replaced by a node ...

In this experience paper, we share our experience on enhancing automatic unit test generation to more effectively find Java null pointer exceptions (NPEs). NPEs are among the most common and critical errors in Java applications. However, as we ...

Interior unsafe is an essential design paradigm advocated by the Rust community in system software development. However, there is little official guidance or few best practices regarding how to encapsulate unsafe code and achieve interior unsafe. To ...

We present CoVeriTeam GUI, a No-Code web frontend to compose new software-verification workflows from existing analysis techniques. Verification approaches stopped relying on single techniques years ago, and instead combine selections that complement ...

Modern automated program repair (APR) tools are well-tuned at repairing single fault programs (i.e., programs in which only one fault can occur at time). However, real-world software projects typically contain multiple bugs at the same time, which can ...

Satisfiability-based automated reasoning is an approach that is being successfully used in software engineering to validate complex software, including for safety-critical systems. Such reasoning underlies many validation activities, from requirements ...

This paper describes a formal repair framework for performance bugs in loop programs, which are programming errors that slow down program execution. The approach is developed based on the observation that a program with a performance bug is a ...

Rust is a relatively new programming language known for its memory safety and numerous advanced features. It has been widely used in system software in recent years. Thus, ensuring the reliability and robustness of the only implementation of the Rust ...

Simulink plays an important role in the industry for modeling and synthesis of embedded systems. Ensuring system stability requires using numerous test cases to validate the functionality and safety of the models. However, as requirements increase, the ...
