Editor's note
CCC (Claude's C Compiler) is a complete C compiler written from scratch in Rust by Claude Opus 4.6, targeting x86-64, i686, AArch64, and RISC-V 64. The project implements every component internally, including a frontend, SSA-based intermediate representation, optimizer, code generator, peephole optimizers, assembler, linker, and DWARF debug info generation, producing ELF executables without any external toolchain. It functions as a drop-in GCC replacement, accepting familiar flags like -O2, -g, -fPIC, and -shared, and can be pointed at existing Make, CMake, or autoconf build systems directly. The compiler has successfully built PostgreSQL (passing all 237 regression tests), SQLite, Redis, the Linux kernel, CPython, QEMU, and over 150 other real-world projects. This repository demonstrates Claude's autonomous coding capability via the Claude API, with a human providing only test cases rather than interactive debugging. Anthropic explicitly cautions against production use, as the code has not been validated for correctness and is confirmed to work only on Linux hosts.
