Symbolic execution is a technique for automatic software validation and verification. New symbolic executors regularly appear for both existing and new languages and such symbolic executors are generally manually (re)implemented each time we want to support a new language. We propose to automatically generate symbolic executors from language definitions, and present a technique for mechanically (but as of yet, manually) deriving a symbolic executor from a definitional interpreter. The idea is that language designers define their language as a monadic definitional interpreter, where the monad of the interpreter defines the meaning of branch points. Developing a symbolic executor for a language is a matter of changing the monadic interpretation of branch points. Our long-term goal is to integrate these techniques in language development workbenches and workflows, to make developer-boosting meta-programming techniques such as symbolic execution readily and automatically available to language designers and software developers. In this paper, we illustrate the technique on a language with recursive functions and pattern matching, and use the derived symbolic executor to automatically generate test cases for definitional interpreters implemented in our defined language.
