Скачать или смотреть Learn Conditional Branching in x86-64 Assembly (YASM/NASM) - CMP, JE, JNE, JL, JG & More

In this practical x86-64 assembly language tutorial we dive deep into conditional branching using YASM (also works with NASM) on Ubuntu/Linux.

We cover:
The CMP instruction and how it sets the RFLAGS register
All major conditional jump instructions (JE, JNE, JL, JLE, JG, JGE, JB, JBE...)
Important difference between signed (JL/JG) vs unsigned (JB/JA) jumps
Real code examples showing how to implement if-style decisions
How to handle the "jump out of range" assembler error
Visual flow diagrams explaining control flow

Perfect for students learning low-level programming, reverse engineering, operating systems, or anyone who wants to understand how if-statements, comparisons, and decisions are actually implemented at the machine level.

Highly recommended companion resource: Professor Ed Jorgensen's free x86-64 Assembly Language Programming book (linked in comments).

Enjoy learning assembly!
