function::u_register — gimme the unsigned value of the CPU register you name, bestie 👑

---

🎀 SYNOPSIS 🎀

u_register:long(name:string)

💅 ARGUMENTS 💅

• name — the name of the register you want back. that's it, that's the whole vibe. you say the register's name, it hands you the value 🫶

🦋 DESCRIPTION 🦋

so it's literally the same as register(name), no cap — EXCEPT. here's the plot twist: if the register is 32 bits wide, it gets zero-extended to 64 bits. ✨

that's the whole difference. that's the tea. 🍓
