As discussed in chat, I'm working on this, but here is a very simple version which might help illustrate the concept. The final version will be much harder to follow,...

Great idea! I'm less concerned with the x86 ones since SDE is a pretty straightforward option there, but for other architectures I think this would be invaluable. Maybe we should...

I don't really have a good way to reproduce this at the moment so it might be a while before this gets fixed, but if you're interested in putting something...

I just pushed a commit (fb6dca9804bef6861fe3a7f82be3d2a6d88fb509) which adds the necessary bits to SSE and implements one function (`_mm_add_ps`) as an example.

Emscripten is working again in CI; I think it was just a buggy release (1.39.7 probably) that was causing the memory issues. Unfortunately attempting to enable WASM SIMD support (with...

The error has been fixed in more recent versions of V8 than Node.js uses. Using latest d8 instead of nodejs to run the tests fixed the problem, and `-msimd128 -s...

@juj, sorry to pull you into this without warning. I see you've been working on [adding SSE support](https://github.com/emscripten-core/emscripten/pull/11193) back into emscripten… It seems like a waste to duplicate efforts, so...

Wow, I sprang this on everyone on a Friday night, I really wasn't expecting such a quick response. Thanks to both of you :) > That's already the case, Emscripten...

> MMX, AVX, AVX2, SSE4.2 and GFNI are out of my scope. Adding support for those in Emscripten though would be really great. Without AVX, I guess FMA will be...

> In general we cannot target Wasm SIMD without some form of cmdline flag, since that affects the set of browsers that one can run the build output with. I...
