Center node: "jsai designing a sound configurable and efficient static analyzer for javascript"
  Abstract: We describe JSAI, an abstract interpreter for JavaScript. JSAI uses novel abstract domains to compute a reduced product of type inference, pointer analysis, string analysis, integer and boolean constant propagation, and control-flow analysis. In addition, JSAI allows for analysis control-flow sensitivity (i.e., context-, path-, and heap-sensitivity) to be modularly configured without requiring any changes to the analysis implementation. JSAI is designed to be provably sound with respect to a specific concrete semantics for JavaScript, which has been extensively tested against existing production-quality JavaScript implementations. #R##N#We provide a comprehensive evaluation of JSAI's performance and precision using an extensive benchmark suite. This benchmark suite includes real-world JavaScript applications, machine-generated JavaScript code via Emscripten, and browser addons. We use JSAI's configurability to evaluate a large number of analysis sensitivities (some well-known, some novel) and observe some surprising results. We believe that JSAI's configurability and its formal specifications position it as a useful research platform to experiment on novel sensitivities, abstract domains, and client analyses for JavaScript.
