24 alternatives to Elfconv – Linux Apps to High-Performance WASM Binary Translator
This post introduces elfconv, a binary translator that converts Linux applications into WebAssembly. repo: https://github.com/yomaytk/elfconv Recently, performance has improved dramatically. In our LINPACK benchmark, the Wasm generated from ELF/AArch64 by elfconv now runs at roughly 60–80% of the performance of the Wasm directly compiled from source code. This shows that elfconv can produce WebAssembly with practical, real‑world performance! Furthermore, compared to QEMU running in the browser, it achieves approximately 68× the performance. Benchmark test:…

I've open sourced a JavaScript to WASM compiler. It's an experimental tool, but given the semantics I already implemented, I'm fairly certain I am able to eventually cover 100% of JavaScript spec. Any ideas, questions or critique welcomed! If you are interested in WASM, especially with new proposals like WASM GC or exception handling, it might be a good source of seeing these features in action - the project has a few thousand lines of hand written WAT so far.

This is the entire Firefox browser rendering to a element. Gecko, all UI components, and the Spidermonkey JS engine are all compiled and running in WebAssembly. Here are a few things you might find interesting: - This is fully end to end encrypted! We use the WISP protocol for TCP-over-websockets. - There is a novel WASM->JS JIT for experimental site speedup - This port cost over 25k in opus/fable tokens for debugging and JIT research This was just a fun experiment to push the boundaries of WebAssembly. For a more usable "browser in browser" experience, we also built…

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 >…

As a personal project I wrote a really tiny Wat 2 Wasm compiler in Go. Mainly for demonstrative and educational purposes. It was tough: I didn't know anything about WebAssembly internals and I'm a newbie with Go... so I tried to document it as much as I could for anyone that would like to approach the quest in the future! It misses a lot of features (that will be gradually implemented). Any feedback is welcomed!! Demo: https://luna-demo.vercel.app

ELF Injector▲39The ELF Injector allows you to "inject" arbitrary-sized relocatable code chunks into ELF executables. The code chunks will run before the original entry point of the executable runs. Included in the project are sample chunks as well as a step-by-step tutorial on how it works. It's a mix of C and assembly and currently runs on 32-bit ARM though it's easy to port to other architectures.

Show HN: TinyWasm - A tiny WebAssembly Runtime written in Rust Hi HN! I'm excited to share TinyWasm (https://github.com/explodingcamera/tinywasm), a WebAssembly Interpreter I developed for my final university project. The main goal of this project was to deepen my understanding of WebAssembly and interpreter design. TinyWasm successfully passes all the official WebAssembly 1.0 tests and also includes features from future proposals such as like bulk memory operations. Initially more of a research project, TinyWasm focuses on simplicity and portability. It has minimal…

A month or so ago, I ported a Common Lisp implementation (npt) to WebAssembly to make a silly blog post, because I was bored and have a lot of time on my hands to waste with things like this (I don't have a job, and because I have next to no experience, these meaningless, silly projects tend to fill what time I do have). This is significant as it's the first time Common Lisp in particular has ever been hosted on it; wasm has a few poor decisions in its design that make it less-than-conducive to being a target for Common Lisp, and a lot of the more interesting implementations require an…

Hi All, I released an EVM/Solidity decompiler recently, here: http://www.eveem.org/ Since it uses symbolic execution underneath, the results are quite awesome. There is also an api that delivers a .json / middle language representation of every contract here: http://eveem.org/code/{{address}}.json The plan is to open-source it as soon as I clean up the code a bit. Spent the last two month crunch-time to get it delivered from scratch :)

Hi everyone, I built a runtime to isolate untrusted code using wasm sandboxes. Basically, it protects your host system from problems that untrusted code can cause. We’ve had a great discussion about sandboxing in Python lately that elaborates a bit more on the problem [1]. In TypeScript, wasm integration is even more natural thanks to the close proximity between both ecosystems. The core is built in Rust. On top of that, I use WASI 0.2 via wasmtime and the component model, along with custom SDKs that keep things as idiomatic as possible. For example, in Python we have a simple decorator:…

Hello! This is the most useless thing I did in quite some time, but it was fun. Compile erlang (actually BEAM) to wasm, statically link with a small http wrapper and run as a request handler under wasmtime. This is not very practical as of now and you better just compile atomvm and statically link it with erlang payload if you really need to run erlang on the edge node (you don't). When (if) typed continuations become a thing, this should also allow for erlang actor model.
