I Built a Rust Compiler for a 20-Year-Old Mac (Borrow Checker and All)

A custom Rust-to-PowerPC compiler written in C, targeting Mac OS X Tiger. It runs on real G4 hardware, has a working borrow checker with NLL, generates AltiVec SIMD code, and implements async/await using the select() syscall. The endgame? Firefox on your 2005 Power Mac.
