Go bindings to system LLVM

Build Status Go Report Card GoDoc

This library provides bindings to a system-installed LLVM.

Currently supported:

  • LLVM 20, 19, 18, 17, 16, 15 and 14 from apt.llvm.org on Debian/Ubuntu.
  • LLVM 20, 19, 18, 17, 16, 15 and 14 from Homebrew on macOS.
  • Any of the above versions with a manually built LLVM through the byollvm build tag. You need to set up CFLAGS/LDFLAGS etc yourself in this case.

You can select the LLVM version using a build tag, for example -tags=llvm17 to use LLVM 17.

Usage

If you have a supported LLVM installation, you should be able to do a simple go get:

go get github.com/goplus/llvm

You can use build tags to select a LLVM version. For example, use -tags=llvm15 to select LLVM 15. Setting a build tag for a LLVM version that is not supported will be ignored.

License

These LLVM bindings for Go originally come from LLVM, but they have since been removed. Still, they remain under the same license as they were originally, which is the Apache License 2.0 (with LLVM exceptions). Check upstream LLVM for detailed copyright information.

This README, the backports* files, and the Makefile are separate from LLVM but are licensed under the same license.
