llvm-hs - Haskell bindings for LLVM

This project aims to provide a relatively complete set of bindings for the LLVM API. If you find that anything is missing please open an issue! We generally try to stay close to the LLVM C++-API so you can consult the LLVM documentation and reuse existing resources.

Contributing

We love all kinds of contributions so feel free to open issues for missing LLVM features, report & fix bugs or report API inconveniences.

Building

Example using Homebrew on Mac OS X:

$ brew update
$ brew install libffi
$ brew install homebrew/versions/llvm39 --all-targets

For Debian/Ubuntu based Linux distributions, the LLVM.org website provides binary distribution packages. Check apt.llvm.org for instructions for adding the correct package database for your OS version, and then:

$ apt-get install llvm-4.0-dev

Versioning

Trying to represent the version of LLVM in the version number but also allowing for version bumps in the bindings themselves while respecting the PVP can be tricky. Luckily LLVM is switching to a new versioning scheme of major.0.patch starting from version 4.0. This means that we can use the last two components for these bindings while the first component indicates the version of LLVM. A special case are the versions 3.major.minor that represent bindings to LLVM 3.9. Bindings to earlier versions are not provided.

How is this related to llvm-general?

This project is a fork of the venerable llvm-general that aims to improve the public release story, and better provide the interfaces needed for any Haskell project looking to leverage LLVM. Contributions are encouraged.
