VAST is a library for program analysis and instrumentation of C/C++ and related languages. VAST provides a foundation for customizable program representation for a broad spectrum of analyses. Using the MLIR infrastructure, VAST provides a toolset to represent C/C++ program at various stages of the compilation and to transform the representation to the best-fit program abstraction.

You can experiment with VAST on compiler explorer. Feel free to use VAST and produce MLIR dialects. To specify the desired MLIR output, utilize the -vast-emit-mlir=<dialect> option. Currently, the supported options are:

• -vast-emit-mlir=hl to generate high-level dialect.
• -vast-emit-mlir=llvm to generate LLVM MLIR dialect.

Refer to the vast-front documentation for additional details.

VAST is licensed according to the Apache 2.0 license. VAST links against and uses Clang and LLVM APIs. Clang is also licensed under Apache 2.0, with LLVM exceptions.
