Portable C Compiler sources

ISPC is a vectorizing compiler and SIMD parallel programming language that implements a single program multiple data model. It serves as a toolchain for translating C-based code with parallel extensions into optimized machine code for various CPU and GPU architectures using an LLVM backend. The compiler is designed for cross-platform SIMD toolchain support, generating specialized instruction sets for x86 SSE/AVX, ARM NEON, and Intel GPU from a single source. It features a runtime dispatch mechanism that selects the most efficient hardware-specific implementation for the current system during

The LLVM-based D Compiler.

Bootstrapped C compiler for 32-bit RISC-V and ARM ISAs

Experimental Go binding for GBDK(GameBoy Development Kit). You can develop GameBoy software using Go!

A Small C Compiler

Chibicc is a C11 compiler designed as a reference implementation for studying compiler construction. It translates C source code into machine-specific assembly instructions by utilizing a pipeline that includes lexical analysis, recursive descent parsing, and single-pass code generation. The project serves as an educational tool for understanding the internal architecture of compilers, from initial tokenization to the final emission of machine code. The compiler distinguishes itself through its self-hosting capability, which allows the software to compile its own source code into a functional

Compile and execute C "scripts" in one go!

This is the home of a D0 compiler. SDC is at the moment, particularly stupid; it is a work in progress. Feel free to poke around, but don't expect it to compile your code.

TinyGo is a specialized compiler and development toolkit designed to bring the Go programming language to resource-constrained microcontrollers and WebAssembly environments. It provides a bare-metal runtime environment that enables high-level code execution without the need for a traditional operating system, utilizing an LLVM-based backend to generate efficient machine instructions. The project distinguishes itself through aggressive optimization techniques tailored for small hardware, including a static memory allocation strategy and whole-program dead code elimination that significantly re

Assembler for Gameboy games

A high-level assembly language for writing homebrew software and games on retro console platforms.

Movfuscator is an obfuscating compiler that transforms C source code into x86 machine code consisting exclusively of move instructions. It implements all program logic, arithmetic, and control flow using a move-only instruction set to hide the execution path and prevent reverse engineering. The project includes a move-only library that performs double precision floating point calculations without using native floating point instructions. It also features a translator that converts these move-only binaries into restricted data transfers and indexed addressing for compatibility with RISC archit
