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
