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
$ git submodule update --init
$ cargo build
Usage
$ rustc -Zcodegen-backend=$(pwd)/target/debug/librustc_codegen_cranelift.so my_crate.rs --crate-type lib -Og
You must compile with
-Og
, because checked binops are not yet supported.
Building libcore
$ git clone https://github.com/rust-lang/rust.git
$ cd rust
$ git apply ../0001-Disable-stdsimd-in-libcore.patch
$ git apply ../0002-Disable-u128-and-i128-in-libcore.patch
$ cd ../
$ ./build.sh
