Yet Another Pointer Analysis for LLVM

Yapall is a precise and scalable pointer analysis for LLVM. The output of Yapall 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 queries

Yapall is k-callsite sensitive for configurable k, field-, array-, and flow-insensitive, and performs on-the-fly callgraph construction. Yapall is written using Ascent and so is highly parallel.

For more information, see the documentation.
