x86-64 Assembly Language Examples

This repository contains examples from the book x86-64 Assembly Language Programming with Ubuntu (v.1.1.14) by Ed Jorgensen provided under CC-BY-NC-SA 4.0. Code will be updated as I progress through examples and projects in the book.

Prerequisites

All examples are written and tested under Ubuntu 18.04 64-bit. Author also recommends Ubuntu distribution, although code should work on any Linux-based 64-bit OS.

Tools

For assembling you will need yasm.

sudo apt-get update
sudo apt-get install yasm

For debugging gdb is used.

$ sudo apt-get install gdb

Build

Sources are organized under ./src folder and follow chapters from the book. All sources can be built by running make from root project directory. Also, every chapter can be individually built. Executables are stored under the same relative path in ./bin folder.

./src $ make                # builds all chapters
./src/chapter_7 $ make      # builds only chapter 7
./src $ make clean          # cleans ./bin dir

Usage

For testing, debugging and checking if code is doing what is suppoed to do gdb (GNU Project Debugger) is used. Another options is to use ddd (Data Display Debugger) if you are uncomfortable with terminal. For each assembly file, I've prepared a _dbg.in file which is gdb Command File. Command files are just list of gdb commands which are then executed sequentially in interactive or non-interactive mode. Example of usage (if you are positioned in root dir):

$ gdb -x dbg/chapter_7/unsigned_byte_operations.in bin/chapter_7/unsigned_byte_operations
