An Easy to Use Infrastructure for Building Static Analysis Tools
This paper deals with design and implementation of an easy to use infrastructure for building static analyzers. The infrastructure provides an abstraction layer called a Code Listener over existing source code parsers like, for example, GCC or Sparse. It is distributed as a C++ library that can be used to build static analyzers in the form of GCC plug-ins. The interface exposed to analyzers is, however, completely independent of GCC, which allows one to run the same analyzer on top of different code parsers without a need to change anything in the analyzer. We describe the key design principles of the infrastructure and briefly introduce its application programming interface that is available to analyzers. The infrastructure is already used in research prototypes Predator and Forester, implementing advanced shape analyses, intended to operate on real industrial code.
