x86-64 Assembly For Loops Explained – YASM Tutorial

This tutorial explains how to implement a C-style for loop in x86-64 assembly using YASM by converting it to while-loop logic with initialization, conditional jump (jl), increment (inc), and unconditional jump back to the loop top. Demonstrates register usage (r12/r13), loop structure, and printing numbers inside the body.

x86-64 Assembly While Loops Explained Step by Step in YASM – From Concept to Working Program

This video teaches how to implement a classic while loop structure in x86-64 assembly language using YASM. We cover the conceptual mapping from C-style while(condition) { body } to assembly labels (while_top, while_body, while_done), conditional jumps (jne, je, etc.), and the unconditional jump back to the top of the loop. A complete runnable example repeatedly reads integers from the user and echoes them until 99 is entered.
