# VAST: MLIR for Program Analysis

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.

For further information check [trailofbits.github.io/vast/](https://trailofbits.github.io/vast/).

## Try VAST

You can experiment with VAST on [compiler explorer](https://godbolt.org/z/3se3q9Tja). Feel free to use VAST and produce MLIR dialects. To specify the desired MLIR output, utilize the `-vast-emit-mlir=` option. Currently, the supported options are:

- `-vast-emit-mlir=hl` to generate [high-level](https://trailofbits.github.io/vast/dialects/HighLevel/HighLevel/) dialect.

- `-vast-emit-mlir=llvm` to generate LLVM MLIR dialect.

Refer to the [vast-front documentation](https://trailofbits.github.io/vast/Tools/vast-front/) for additional details.
