Chrome does nothing with asm.js; it's Firefox who applies special, faster compilation routines to asm.js code.

It was announced in V8 6.1 that asm.js could be validated and compiled to WebAssembly. https://v8project.blogspot.se/2017/08/v8-release-61.html

To be fair I don't think this announcement ever spread that far and I don't think it was ever announced that the validation would be enabled in Chrome, nevertheless I see asm.js validation messages (or rather, invalidation messages when there's issues) in Chrome 64.

Not sure about Chrome, but the support in Chromium has already been shipped last year: https://bugs.chromium.org/p/v8/issues/detail?id=4203

Oh, so it changed! Didn't know that, thanks. When playing with Emscripten, I'm still seeing asm.js working noticeably faster in Firefox than in Chromium, so I just assumed that it's still how it was for years :)

Web assembly is now supported across all major browsers.

asm.js is not webassembly.
