I recently improved support for 64-bit integers in Cheerp, a C/C++ to WebAssembly/JavaScript compiler.
In this post I will explain why supporting 64-bit integers requires special attention, what Cheerp used to do in the past, why the current situation is better, and what we will be able to do in…
WebAssembly in its current MVP form is shipped by all major browsers and is already capable of amazing things. This does not mean that its development has concluded: on the contrary, there are many post-MVP feature proposals at different stages of development.
One such proposal is about adding the so-called…
At Leaning Technologies, we provide solutions for porting traditional desktop applications to the Web. Our C++ compiler Cheerp generates a combination of WebAssembly and JavaScript, allowing both easy interoperability with the browser and performance.
As a showcase project we decided to port a multiplayer game to the Web, and we…
I work on Cheerp, a C++ to JavaScript and WebAssembly compiler based on LLVM.
One of the challenges of compiling LLVM IR code to JavaScript and WebAssembly is the structured control flow problem: We have some code represented as a control flow graph (CFG), and we want to convert it…
A few months ago I saw this blog post by Mozilla, which is about rewriting part of their source-map library in rust code compiled to WebAssembly.
I highly recommend reading it, as it shows in details a practical example of using WebAssembly to improve the performance of a JavaScript library.
