A C compiler written entirely from scratch in Rust by Claude Opus 4.6, with no external toolchain dependencies. It includes a frontend, SSA-based IR, optimizer, code generators for x86-64, i686, AArch64, and RISC-V 64, plus its own assembler, linker, and DWARF debug info generation, producing Linux ELF executables.
Use cases
- compile C programs without GCC or Clang installed
- cross-compile C code for ARM, RISC-V, or 32-bit x86
- build the Linux kernel with an alternative C compiler
- drop-in GCC replacement for make, CMake, or configure-based builds
- study how a complete compiler toolchain is implemented from scratch
- evaluate LLM-generated compiler code quality
When to choose
- you want a dependency-free C compiler that emits ELF binaries on Linux
- you need to cross-compile C for x86-64, i686, AArch64, or RISC-V 64 with sysroots available
- you are experimenting with alternative compilers or researching AI-written software
When to avoid
- you need a validated, production-grade compiler - correctness has not been verified and the maintainer explicitly discourages production use
- you develop on macOS or Windows - it was only tested on Linux hosts
- you rely on full GCC/Clang language extensions, diagnostics, or optimization maturity
