    c

    c

    Compile and execute C "scripts" in one go!

    I love C for its raw speed (although it does have its drawbacks). We should all write more C. With this shell script, you can compile and execute C "scripts" in one go! (Oh yeah, and it works for C++ too.) First of all, I want to clarify why this is not the same as tcc -run. TCC is a compiler. We all know that. TCC will perform its own set of optimizations, just as GCC will perform its own and Clang will perform its own. The purpose of this script is to give a simple front-end to your...

    Smaller C

    Smaller C

    Simple C compiler

    Smaller C is a simple and small single-pass C compiler, currently supporting most of the C language common between C89/ANSI C and C99 (minus some C89 and plus some C99 features). Currently, it generates 16-bit and 32-bit 80386+ assembly code for NASM that can then be assembled and linked into DOS, Windows, Linux and Mac OS X programs. (You may use YASM or FASM instead of NASM) Code generation for MIPS CPUs is also supported (primarily for RetroBSD). The compiler is capable of compiling...

    Cython

    Cython

    The most widely used Python to C compiler

    Cython is an optimizing static compiler for both the Python programming language and the extended Cython programming language (based on Pyrex). It makes writing C extensions for Python as easy as Python itself. Write Python code that calls back and forth from and to C or C++ code natively at any point. Easily tune readable Python code into plain C performance by adding static type declarations, also in Python syntax. Use combined source code level debugging to find bugs in your Python, Cython, and C code.

    Claude Opus 4.6 wrote a dependency-free C compiler in Rust

    Claude’s C Compiler is a remarkable experiment in automated software generation: a full C compiler written from scratch in Rust entirely by an AI model (Claude Opus 4.6) with minimal human intervention, capable of targeting multiple architectures like x86-64, i686, ARM, and RISC-V. The project implements every part of a traditional compiler — the lexer, parser, intermediate representation, optimizer, code generator, assembler, linker, and debug info emitter — without relying on any external...
