Cool to hear there aren't any technical blockers to add Windows support! You just convinced me into giving OxCaml a try for a hobby project. 128-bit SSE is likely to be enough for my use case and target specs.

David Allsopp had an oxcaml branch compiling on Windows a few months ago, so it’s in the queue…

FWIW, the "Get OxCaml" page actually says that SIMD on ARM isn't supported yet. If it actually works it would be worth removing that from the known issues list https://oxcaml.org/get-oxcaml/

Indeed, it says that because we don't have a library of NEON intrinsics (like ocaml_simd_sse) yet, but the extension itself works.

Ah, that clears it up a bit. Thanks! Looking forward to all of this. (For the interested readers, here's the SSE library: https://github.com/janestreet/ocaml_simd/tree/with-extension...)

This is so cool.
