Compiler verification: Challenges and Benefits

This lecture by the instructor explores the challenges and benefits of compiler verification, focusing on the formal verification of compilers for high-assurance software. The lecture delves into the history of compiler verification, the intricacies of compiler optimization, and the delicate nature of code generation. It discusses the importance of verifying compilers for critical software, the concept of verified compilers, and the impact of miscompilation bugs. The lecture also covers the CompCert project, which aims to develop and prove correct a realistic compiler for critical embedded software. Through examples and case studies, the lecture highlights the significance of formal verification in ensuring the reliability and safety of compilers.
