This thesis explores the construction and correctness of modular compilers. Modular compilation is a compiler construction technique allowing the construction of compilers for high-level programming languages from reusable compiler building blocks. Modular compilers are defined in terms of denotational semantics based on monads, monad transformers, and a new model of staged computation called metacomputations. A novel form of denotational specification called observational program specification and related proof techniques are developed to assist in modular compiler verification. It will be demonstrated that the modular compilation framework provides both a level of modularity in compiler proofs as well as a useful organizing principle for such proofs.
