LLVM C API wrapper

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.

Requirements

LLVM.jl is supported on Julia 1.10+, and thus requires LLVM 15 or later. By default it uses the LLVM library shipped with Julia. 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).

Other LLVM libraries, like the one provided by your operating system, can not be used. Instead, LLVM.jl can build standalone libraries for other versions of LLVM, and use them next to Julia's own. Select a library for a group of operations with LLVM.library!, or select a context and its library together with context!; see Using other LLVM libraries in the manual.

Installation

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")
