RandomX.js and EquiX.js

More of the same today, except stream is a day early.

Agenda. I need to look into the FMA issues so I can decide whether or not to gut it from the VM/build, or make it a requirement if I’m able to re-enable it on the JIT side.

Look into FMA issues. FIXED! ✅ 2026-01-13
Testing doesn’t depend on Bun’s bullshit. ✅ 2026-01-13

tests(#1768255200): make tests use vitest instead of bun test (testing on node + bun)
jit+semifloat(#1768255200): enable and fix the FMA semifloat (JIT_FMA)

Make the codebase easy to build without 20 different tools, make it not shit. Try and reduce the amount of binary patching tools I use as well.
RandomX batching API (mining from that).
(Look into?) Improving JIT code patterns, precomputing scratchpad addresses etc.
(Look into?) Register allocation etc (since we only get baseline), cryptography code.

Aftermath

FMA works!! See: https://github.com/l1mey112/randomx.js/issues/1#issuecomment-3741184392

It was entirely due to my own stupidity. Hopefully I can be redeemed later.

~~I am seeing +0.5 to 1.0 H/s already, so this seems quite good.~~

This is more like a +5 H/s. Much better!
