## Usage

### Cargo
```bash
$ $cg_clif_dir/cargo.sh run
$ CHANNEL="release" $cg_clif_dir/cargo.sh run
```
If you compiled cg_clif in debug mode you should use `CHANNEL="debug"` instead or omit `CHANNEL="release"` completely.
### Rustc
```bash
$ rustc -Cpanic=abort -Zcodegen-backend=$cg_clif_dir/target/debug/librustc_codegen_cranelift.so --sysroot $cg_clif_dir/build_sysroot/sysroot my_crate.rs
$ rustc -Cpanic=abort -Zcodegen-backend=$cg_clif_dir/target/release/librustc_codegen_cranelift.so --sysroot $cg_clif_dir/build_sysroot/sysroot my_crate.rs
