Deep Dive into Function Call Implementation: From Assembly to CPU Registers

This article thoroughly explains low‑level function call implementation, covering Intel and AT&T assembly syntax, the evolution of CPU registers from 16‑bit to 64‑bit x86, caller‑ and callee‑saved conventions, stack‑based to register‑based parameter passing, stack frame setup, and assembly representations of control structures.
