Can you believe it. I can't either. Just by not pulling in the regex crate I made the binary so much smaller and wasm-opt doesn't take a milllion years now. Anyway, I wrote it using Rust's portable simd feature which I enjoyed writing. GCC has some QoL operations for intrinsics but this is still way better. It's also portable so say goodbye to writing multiple kernels. I wish Rust slices had a "fill" syntax so I can specify that the rest of the slice will be filled with a default vaule I specify. I wonder what an LLM would write so I used the LLM used by the Department of Defense (Claude) but it couldn't SIMDify the whole algorithm even though I asked it to try and figure out SIMD parsing and stuff. Useless. + +Rust really doesn't want you to do stuff it doesn't like, I used the <a href="https://git.neetlo.li/ataxia/commit/?h=main&id=bfc2cabc3b0d6af8c7ca0496b7bd815fdbb658f6" class="splink">internal negative Freeze trait</a> to implement my own UnsafeCell so it wouldn't put stuff in .rodata.

I do not recommend it. P.S.: If you're writing code for WASM and Cloudflare Workers and your math code throws a fit, you might want to add: |
