NEAT: QCP: A Practical Separation Logic-based C Program Verification Tool

Abstract: As software systems increase in size and complexity dramatically, ensuring their correctness, security, and reliability becomes an increasingly formidable challenge. Despite significant advancements in verification techniques and tools, there still remain %these tools still continue to encounter substantial difficulties when applying these tools to complex, real-world scenarios. To address these difficulties, this paper introduces a novel verification tool, called \textbf{Qualified C Programming Verifier (QCP)}. QCP incorporates a refined front-end %syntax of assertion language to enhance user interaction. The proposed assertion language aims to %syntax is designed to lower the entry barrier for verification tools, improve proof efficiency by improving automation, and facilitate a deeper understanding of both the program and its verification results.
