Wasmer Compiler - LLVM

This is the wasmer-compiler-llvm crate, which contains a compiler implementation based on LLVM.

Usage

First, add this crate into your Cargo.toml dependencies:

wasmer-compiler-llvm = "1.0.0-alpha.1"

And then:

use wasmer::{Store, JIT};
use wasmer_compiler_llvm::LLVM;

let compiler = LLVM::new();
// Put it into an engine and add it to the store
let store = Store::new(&JIT::new(&compiler).engine());

When to use LLVM

We recommend using LLVM as the default compiler when running WebAssembly files on any production system, as it offers maximum peformance near to native speeds.

Requirements

The llvm compiler requires a valid installation of LLVM in your system. It currently requires LLVM 10.

You can install LLVM easily on your debian-like system via this command:

bash -c "$(wget -O - https://apt.llvm.org/llvm.sh)"

Or in macOS:

brew install llvm

Or via any of the pre-built binaries that LLVM offers.
