Rust GCC Front-end
summary
A full Rust front end for GCC that parses, macro-expands, type-checks and lowers Rust into GCC trees and reuses libcore/libstd is under active development, aiming to be a usable alternative to rustc. Current work focuses on compiling libcore 1.49 (with some experiments on 1.29), implementing intrinsics, closures and big types, matching Rust error codes, and a Polonius-based borrow checker branch. Integration notes: GCC-style flags for invocation, no Cargo in kernel builds, and ongoing versioning plans to declare a minimum Rust target.
