Building a modular static analysis framework in Scala (tool paper)

Abstract

We present Scala-AM, a framework for implementing static analyses as systematically abstracted abstract machines. Analyses implemented on top of Scala-AM separate operational semantics from machine abstraction concerns. This modularity facilitates varying the analyzed language and the applied abstraction method in an analysis. We describe the design of our framework and demonstrate its use in a static analysis for the DOT calculus. We conclude with a tour of the features of Scala through which Scala-AM achieves its modularity.
