Book excerpt: Abstract: "We describe the formal verification of a simple compiler using the HOL theorem proving system. The language and microprocessor considered are a subset of the structured assembly language Vista, and the VIPER microprocessor, respectively. We describe how our work is directly applicable to a family of languages and compilers and discuss how the correctness theorem and verified compiler fit into a wider context of ensuring that object code is correct. We first show how the compiler correctness result can be formally combined with a proof system for application programs. We then show how our verified compiler, despite not being written in a traditional programming language, can be used to produce compiled code. We also discuss how a dependable implementation might be obtained."
