Work in progress cranelift codegen backend for rust

⚠⚠⚠ This doesn't do anything useful yet ⚠⚠⚠

Building

$ git clone https://github.com/bjorn3/rustc_codegen_cranelift.git
$ cd rustc_codegen_cranelift
$ rustup override set nightly
$ git submodule update --init
$ cargo build

Usage

$ rustc -Zcodegen-backend=$(pwd)/target/debug/librustc_codegen_cranelift.so my_crate.rs --crate-type lib -Og

Building libcore

$ rustup component add rust-src
$ ./prepare_libcore.sh
$ ./build.sh

Not yet supported

  • Checked binops

  • Drop glue

  • Other call abi's

  • Sub slice

  • Inline assembly

  • Custom sections

Known errors

  • cranelift-module api seems to be used wrong, thus causing panic for some consts
  • cranelift-codegen doesn't have encodings for some instructions for types smaller than I32
