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 --release
Usage
$cg_clif_dir is the directory you cloned this repo into in the following instruction.
Cargo
$ 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
$ rustc -Cpanic=abort -Zcodegen-backend=$cg_clif_dir/target/release/librustc_codegen_cranelift.so --sysroot $cg_clif_dir/build_sysroot/sysroot my_crate.rs
Not yet supported
- Good non-rust abi support (several problems)
- Checked binops (some missing instructions in cranelift)
- Inline assembly (no cranelift support, not coming soon)
- SIMD (tracked here, some basic things work)
