Kcc – a C17 compiler built solo with an LLM on $100/month, no agents
kcc — A Formal C17 Compiler in ARM64 Assembly kcc is a formal C17 compiler written entirely in ARM64 assembly, and set down as a single literate program using weft, a metalanguage built to be authored and read by human and AI collaborators alike. Every instruction is explained in prose before it is written in code. It checks C against the Standard, optimises it, allocates registers, and emits native machine code; it compiles itself to a byte-identical binary; and it cross-compiles to x86-64 (Linux and macOS).

Opening excerpt (first ~120 words) tap to expand
kcc — A Formal C17 Compiler in ARM64 Assembly kcc is a formal C17 compiler written entirely in ARM64 assembly, and set down as a single literate program using weft, a metalanguage built to be authored and read by human and AI collaborators alike. Every instruction is explained in prose before it is written in code. It checks C against the Standard, optimises it, allocates registers, and emits native machine code; it compiles itself to a byte-identical binary; and it cross-compiles to x86-64 (Linux and macOS). It builds and runs Lua, SQLite, and DOOM — and boots a Linux kernel. The whole book is the compiler (≈1000 pages): read kcc.pdf in this repository, also published on Releases, or build it yourself (see below).
