Ask HN: Real-world examples of WASM usage
Yours is a fair question. I think that, right now, adoption of WebAssembly is quite limited. On the other hand (here at LeanigTech) we are extremely bullish about its potential.
We believe that this technology would be adopted more with better tooling. Our main contribution to this space is Cheerp: A C++-to-WebAssembly _and_ JavaScript compiler (https://github.com/leaningtech/cheerp-meta/). It is designed to seamlessly take advantage of Wasm without sacrificing easy access to Web APIs, all from within C++ with no need of post-processing and glue code.
We know for a fact that amazing products can be build with Cheerp, because we have done it ourselves.
CheerpX is a x86 virtual machine running in the browser, fully written in C++ and compiled with Cheerp. It includes a JIT-compiler that is able to analyze x86 binary code and emit new WebAssembly modules on the fly.
Our most impressive demo yet (WebVM) is available here: https://webvm.io/

A JavaScript optimizing compiler
A similar project, for WebAssembly so with limited scope is this: https://github.com/bytecodealliance/wizer. And somehow similar but limited on LLVM IR a colleague worked on this for Cheerp (the compiler used here as backend): https://github.com/leaningtech/cheerp-meta/wiki/Cheerp-PreExecuter.

Cheerp 3.0: The most advanced C++ compiler for the Web now permissively licensed
I'm particularly curious on what parts cheerp adds to their clang+llvm base. Presumably it's something like the C standard target library for WASM/JS?
For reference, here's examples of what you could do with the baseline clang with wasm (but not JS?) [1] [2] [3], referenced from a similar thread on HN.
