## What it is
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

## Facets
- artifact type: cli-tool
- maturity: experimental
- function: compiler, programming-language, developer-tools
- domain: compilers, programming-languages, developer-tools
- platform: cross-platform, cli
- tags: gcc, rust, compiler-front-end, gnu-toolchain, alternative-compiler, linux
