Rust on Dreamcast

Rust, a systems programming language known for its focus on memory safety and performance, is gaining popularity. While Rust is typically compiled with LLVM, which doesn't support Dreamcast's SuperH architecture, developers have found workarounds. Two solutions are available: rustc_codegen_gcc and gccrs. The former is more advanced, allowing for core and alloc support but lacking full std functionality. Developers can use rustc_codegen_gcc with the Rust-for-Dreamcast repository and kos-rs crate to compile Rust programs for Dreamcast. The project is still in active development, with ongoing improvements and changes. Key features like libcore, liballoc, and linking to KallistiOS are supported, while work on libc and libstd is in progress. Future goals include better KallistiOS bindings and official support for libc/libstd. Developers interested in using Rust for Dreamcast must set up a KallistiOS development environment, build a cross-compiling libgccjit.so, and configure rustc_codegen_gcc accordingly. The process involves applying patches, scripts, and wrappers provided by the Rust-for-Dreamcast repository to compile and build Rust programs for Dreamcast successfully.
