For the past year I have been working on a new architecture for CheerpJ, @leaningtech's solution to run real-world #Java applications in modern browsers. The 3.0 version will be fully JIT based. The first real #WebAssembly replacement for the JVM. leaningtech.com/announcing-c…

The @googlechrome devtools are great, but they are inadequate when working on very large apps, especially when JIT-ting #WebAssembly. @panicodes has recently joined our team and fully revamped our internal profiling tools. We are releasing them as well! leaningtech.com/beyond-the-d…

Today we are releasing Cheerp 3.0, our state-of-the-art C++ to #WebAssembly _and_ #JavaScript compiler. Lots of improvements in performance, output size and interoperability features. But, most importantly, Cheerp is low permissively licensed! leaningtech.com/cheerp-3-0-t…

Very happy to share another very big leap my colleagues have been working on recently: webvm.io/?networking. Now #WebVM gets [optional] networking capabilities, closing the gap between an emulated terminal inside a browser tab and the real thing.

This piece pulls it all together! Terrific work by @leaningtech folks, and the ubiquity of @Tailscale continues to surprise me.
Leaning Technologies@leaningtech6 Oct 2022
Added support for TCP and UDP networking has been a highly requested feature by early adopters of #WebVM We designed it so it can be integrated into our other WebAssembly toolchains, with CheerpJ (JVM replacement for the browser) in mind in particular. leaningtech.com/webvm-virtua…

With great pride we are releasing an upgrade to WebVM: our #WebAssembly powered X86 virtual machine running fully client side. We now even support TCP and UDP traffic, via @Tailscale DERPs! Turns out networking from a browser tab was possible after all. leaningtech.com/webvm-virtua…

This is the second web engine implementation that will unblock tail calls from moving to phase 4! Very exciting to see new progress here. Thanks to @leaningtech for working on this!

WebAssembly tail-call proposal is for now supported by V8, that powers Chrome-family or Edge browsers, plus node and deno, while when this PR (github.com/WebKit/WebKit/pul…) will allow JavaScriptCore (behind Safari and the newer addition #bunjs) to get there. 3/4

PartialExecuter: a new generic LLVM IR optimization that compile unused code away thanks to an Interpeter-like routine that executes at compile time. Code has been merged in Cheerp, it works, now the article is out: medium.com/leaningtech/parti…

PartialExecuter: Reducing WebAssembly size by exploring all executions in LLVM

Adding a new IR optimization that allows to compile unused code away in Cheerp. Idea generation, pseudo-code, and some magic with graphs.

Thanks to the team @leaningtech for helping pull this out, and in particular to @alexpignotti for the extensive code review sessions. We believe this to be the first of a new class of optimizations on LLVM's IR. Looking forward to any feedback!
