24 alternatives to Cj–tiny no-deps JIT in C for x86-64 and ARM64
Hey y’all! About 7 years ago, I had this idea to write a JIT with an autogenerated backend for x86 based on the ISA specs. I sketched something out and then just kinda let it sit. I picked it up again a few weeks ago and made a complete-ish backend for both x86 and ARM64. It has no dependencies, the backends are completely autogenerated (by horrible, horrible JS scripts), and I built a small abstraciton layer for things like functions prologues etc. It’s super duper early and will probably break on your machine, but it’s good enough to compile some cool examples (look at the examples…
Cj is a lightweight JIT compiler written in C that generates machine code for x86-64 and ARM64 processors. It features autogenerated backends derived directly from ISA specifications and includes no external… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

CJIT▲83CJIT started as a hobby project around Fabrice Bellard’s tinyCC and slowly grew into something much more practical. It is now a small portable C compiler and runner that works across Linux, macOS, and Windows, can self host, and is packaged as a single executable. What mattered most to me was keeping the barrier to entry low. You can take one small binary, drop it onto a system, and compile or run C code using the libraries already available there, without setting up a full toolchain or installing a large stack of dependencies. I find that useful for quick prototyping, testing, auditing,…

Repo: https://github.com/valdanylchuk/xcc700 Hi Everyone! I just wrote my first compiler! - single pass, recursive descent, direct emission - generates REL ELF binaries, runnable using ESP-IDF elf_loader - very basic features only, just enough for self-hosting - treats the Xtensa CPU as a stack machine for simplicity, no register allocation / window usage - compilable on Mac, probably also Linux, can cross-compile for esp32 there - wrote for fun / cyberdeck project Sample output from esp32: xcc700.elf xcc700.c -o /d/cc.elf [ xcc700 ] BUILD COMPLETED >…

Long-simmering side project that is finally ready to see the light. HAMTs are a cool persistent data structure and implementing one has been a lot of fun. Beyond the code, there is likely some value in the extensive and largely complete implementation docs; basic benchmarks are linked in the README, too. Kind of aiming to be "the libavl for HAMTs". That is obviously a high and aspirational bar but a distinct possibility if it stirs up a little interest and/or contribution. Anyways, it's time for this to go out, collect feedback and maybe even some use outside of toy projects. Let me…

This is ymawky, a static file web server for MacOS written entirely in ARM64 assembly. It supports GET, PUT, DELETE, HEAD, and OPTIONS requests, and supports Range: bytes=X-Y headers (which allows scrubbing for video streaming). It decodes percent-encoded URLs, strictly enforces docroot, serves custom error pages for any HTTP error response, supports directory listing, and has (some) mitigations against slowloris-like attacks. I’ve also written a more detailed writeup here: https://imtomt.github.io/ymawky/

Hi all! I'm going into my freshman year, and figured that the best way to prepare for the intro to programming Racket course would be to implement my own garbage-collected, dynamically typed, functional programming language in C ;) Anyways... here's the repo: https://github.com/liam-ilan/crumb I started learning C over the summer, so I still have a whole lot to learn... Any feedback would be greatly appreciated! :D

Hi! I've been working on the flipjump project, a programming language with 1 opcode: flip (invert) a bit, then jump (unconditionally). So a bit-flip followed by more bit-flips. It's effectively a bunch of NOT gates. This language, as poor as it sounds, is RICH. Today I completed my compiler from C to FlipJump. It takes C files, and compiles them into flipjump. I finished testing it all today, and it works! My key interest in this project is to stretch what we know of computing and to prove that anything can be done even with minimal power. I appreciate you reading my announcement, and be…

Personally, I think the JJ VCS (https://github.com/jj-vcs/jj) hit a point some time in this past year where I find it hard to find a great reason to continue using git. Over the years I've cobbled together aliases and bash functions to try to improve my git workflow, but after using jj, which works with ~any git repo and integrates great with Github repos, all of the workflow issues I ran into with git are not only solved, but improved in ways I couldn't manage with simple scripts. One example is the op log, which lets you go to any point in your repo's time and provides…

I have been working on this game somewhat sparsely for the past three years or so. However, it is still in a very early stage, and there is a lot of work to do. One of my friends encouraged me to post about it here, since he felt people might find interesting how I don’t use any libraries for it. The game can be played on a browser by virtue of WebAssembly. There are native ports using either MiniFB or SDL2, but you have to build those yourself. I decided to write the game in C because I feel like it is a simple language that a lot of people can understand well enough, and I didn’t think I…
