This paper reports on provably correct compiler implementation in the ESPRIT basic research action 3104 ProCoS (Provably Correct Systems). A sharp distinction is drawn between correctness of the specification of a compiler and correctness of the actual implementation. The first covers semantical correctness of the code to be generated, whereas the second concerns correctness of the compiler program with respect to the specification. The compiler construction framework presented aims at minimizing the amount of handcoding during implementation and at reusing specification correctness arguments for proving the implementation correct. The classical technique of bootstrapping compilers is revisited with respect to implementation correctness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
