asm: Learn Linux x86_64 Assembly Programming

Overview

0xAX/asm is a learning resource that teaches assembly programming for x86_64 processors on GNU/Linux. It addresses the gap between higher-level programming and machine-level execution through explanations paired with code examples.

The material is organized as a seven-part series, from processor concepts and stack use to floating-point arithmetic and calling assembly from C. It is a fit for readers who want a guided introduction rather than a reference covering multiple architectures or operating systems.

Key Features

• Seven chapters progress from introductory concepts to assembly and high-level language interaction.
• Explains x86_64 processor concepts and the structure of Linux programs.
• Covers memory allocation, stack and heap, and system calls.
• Introduces floating-point representation and arithmetic.
• Includes code examples in the examples directory.
• Offers the posts as a downloadable PDF book.
• Lists volunteer translations in Chinese, Turkish, Korean, and Russian.

Use Cases

• A programmer starting with assembly can follow the chapters and build a foundation in x86_64.
• A Linux learner can use the examples to explore how programs interact with the operating system through system calls.
• A C programmer can consult the later material when learning how to call assembly code from C.
• An instructor or independent learner can use the chapter sequence and examples as supplementary course material.

Getting Started

Read the repository README and begin with Part 1: Introduction. To run the examples, use a 64-bit Linux distribution with make, NASM, and binutils installed. See the README for the full chapter list and PDF download.

Alternatives

• asm-lessons: This teaches assembly through FFmpeg code and contribution-oriented lessons, while asm focuses on runnable NASM examples for Linux x86_64 and OS interaction.

Considerations

• The lessons and examples focus on x86_64 and GNU/Linux, not other architectures or operating systems. ARM64 material is described as a future plan.
• Running the examples requires a 64-bit Linux distribution, make, NASM, and binutils.
• The Markdown content is licensed CC BY-NC-SA 4.0, which requires attribution, prohibits commercial use, and requires adaptations to use the same license. The repository metadata reports the license as NOASSERTION.
• The README notes that translations may diverge from the original content.
