Oxidized GCC #

Part of the overby.me monorepo, where this lives in safety/oxidized/gcc and where all development happens.

It is also published on its own, as tangled.org/overby.me/oxidized-gcc and github.com/overby-me/oxidized-gcc. Both are read-only mirrors, rebuilt from the monorepo with josh: a commit made to either is overwritten by the next sync, so please open issues and pull requests on the monorepo.

A GCC-compatible C compiler written in Rust, targeting x86-64, i686, ARM64, and RISC-V.

Based on Claude's C Compiler (ccc) by Anthropic.

Usage in rust-nixpkgs #

This package is intended as a drop-in GCC replacement for the Rust stdenv in nixpkgs. It includes a built-in assembler and linker, removing the dependency on GNU binutils for many packages.
