c3c is the compiler for the C3 programming language, transforming source code into executable binaries, static libraries, or dynamic libraries using an LLVM backend. It implements a system based on result-based error handling, scoped memory pooling, and a semantic macro system.
The compiler provides first-class support for hardware-backed SIMD vectors that map directly to processor instructions and enables runtime polymorphism through interface-based dynamic dispatch.
The project covers a broad set of low-level capabilities, including manual and pooled memory management, inline assembly integration, and a comprehensive metaprogramming suite featuring compile-time execution and reflection. It maintains full ABI compatibility with C and C++ and supports multi-target cross-compilation for platforms such as WebAssembly, Linux Musl, and Android.
Integrated toolchain features include a project build coordinator, automated SDK fetching, and a built-in HTML documentation generator that extracts contracts and comments directly from the source.
