Concolic Execution for Testing Definitional Interpreters

Definitional interpreters are difficult to test with a pre-defined test suite. This paper tries to determine the effectiveness of automatic testing of definitional interpreters, using concolic execution. First we develop a model for concolic execution of a functional language. Then we identify different categories of common mistakes when writing...

DynSem: A DSL for Dynamic Semantics Specification

The formal definition the semantics of a programming language and its implementation are typically separately defined, with the risk of divergence such that properties of the formal semantics are not properties of the implementation. In this paper, we present DynSem, a domain-specific language for the specification of the dynamic semantics of...
