🦋 DESCRIPTION 🦋

So like, this function asks your CPU "hey girl, do you have SSE4.1 features?" and reports back.

Here's the tea tho: on CPUs that aren't using Intel instruction sets, this always returns false. Always always. No exceptions, no cap. not me catching strays just for having a different instruction set 😭

• false — nope, she doesn't have them

that's it. that's the whole thing. binary queen 🍓
