$ ./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.

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

Cargo

$ RUSTFLAGS="-Cpanic=abort -Zcodegen-backend=$cg_clif_dir/target/debug/librustc_codegen_cranelift.dylib --sysroot $cg_clif_dir/build_sysroot/sysroot" cargo run

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.
