WIP Cranelift codegen backend for rust

⚠⚠⚠ Threads and certain kinds of FFI don't work yet. ⚠⚠⚠

Building

$ git clone https://github.com/bjorn3/rustc_codegen_cranelift.git
$ cd rustc_codegen_cranelift
$ ./prepare.sh # download and patch sysroot src and install hyperfine for benchmarking
$ ./test.sh

Usage

$cg_clif_dir is the directory you cloned this repo into in the following instruction.

Cargo

$ $cg_clif_dir/cargo.sh run

Rustc

$ rustc -Cpanic=abort -Zcodegen-backend=$cg_clif_dir/target/debug/librustc_codegen_cranelift.so --sysroot $cg_clif_dir/build_sysroot/sysroot my_crate.rs

Not yet supported

Troubleshooting

Can't compile

Try updating your nightly compiler. You can try to use an nightly a day or two older if updating rustc doesn't fix it. If you still can't compile it, please fill an issue.
