gccrs is a GCC front-end implementing the Rust language, aiming to be fully upstreamed into the GNU toolchain as an alternative to rustc/LLVM. It is in a very early stage and cannot yet compile real Rust programs, with borrow checking planned via the polonius effort.

Use cases

• compile rust programs with gcc instead of llvm
• alternative rust compiler front-end for gcc
• use gcc optimization passes on rust code
• contribute to a rust compiler implementation
• compare gcc vs llvm codegen for rust
• port rust to platforms supported by gcc

When to choose

• you want to experiment with or contribute to an alternative Rust compiler
• you need GCC's middle-end optimizations or target support for Rust
• you're researching compiler front-end design in GCC

When to avoid

• you need to build real Rust projects today - use rustc instead
• you need borrow checking and full language compliance
• you want a stable, production-ready toolchain
