ourc v0.1: a Rust compiler grown from 269 bytes of hand-written machine code.

  • Compiles a subset of Rust to native x86-64 Linux executables (via LLVM llc and cc), and refuses the rest. A program it accepts runs as rustc's build of it does.
  • rustc 1.99.1 tests/ui: 10,837 of 20,072 tests passed; 0 wrong answers among the 3,676 run-pass programs compared with rustc.
  • Compiles its own 51,210-line source to a byte-identical fixed point.

ourc sha256: 10b9c17a1886a9e063499c544434f370f1c257057562c85dbd9ab03379354144

Built with LLVM 22.1.8, GCC 16.2.1, binutils 2.47 and glibc 2.44. To rebuild it from the hand-written hex instead of trusting this binary, see Verify it yourself.

The binary needs x86-64 Linux, llc (LLVM 16 or newer) and cc. See README.md and LIMITATIONS.md in the tarball.
