cclyzer++

cclyzer++ is a precise and scalable global pointer analysis for LLVM code. The output of cclyzer++ can be used for a variety of program analysis tasks, including:

  • Creation of callgraphs with precise handling of indirect function calls and virtual method calls
  • Precise inter-procedural control- and data-flow analysis
  • Answering may-alias and must-not-alias queries

See the :ref:`design documentation <design>` for further explanation and examples of the output of cclyzer++.

cclyzer++ is field- and array-sensitive, performs on-the-fly callgraph construction, and supports many different configurations of :ref:`context-sensitivity <context-sensitivity>` including k-callsite sensitivity. It has subset-based (Andersen style) and unification-based (Steensgaard style) analyses. cclyzer++ is written in Soufflé Datalog, and so is highly parallel. cclyzer++ was derived from cclyzer.

Documentation is also available online.

cclyzer++ is actively developed and maintained by Galois, Inc.
