A Julia wrapper for the LLVM C API.

The LLVM.jl package is a Julia wrapper for the LLVM C API, and can be used to work with the LLVM compiler framework from Julia. You can use the package to work with LLVM code generated by Julia, to interoperate with the Julia compiler, or to create your own compiler. It is heavily used by the different GPU compilers for the Julia programming language.

LLVM.jl is supported on Juila 1.8+, and thus requires LLVM 13. However, the package is really only intended to be used with the LLVM library shipped with Julia. That means you can not use it with other LLVM libraries, like the one provided by your operating system. It is recommended to use the official binaries from julialang.org, but custom builds are supported too (as long as they provide a dynamically-linked copy of the LLVM library).

LLVM.jl can be installed with the Julia package manager. From the Julia REPL, type ] to enter the Pkg REPL mode and run:

pkg> add LLVM

Or, equivalently, via the Pkg API:

julia> import Pkg; Pkg.add("LLVM")
