This 2005 PDF is supplemental material for an old edition of "Computer Systems: A Programmer's Perspective” by Randal E. Bryant and David R. O'Hallaron. The 2015 edition of the book includes an updated version of this x86-64 content in Chapter 3, replacing the IA32 content and no longer a just a supplement. I strongly recommend owning a copy of this book if you have any interest in systems programming or just want to be exploit hardware characteristics for better performance in your userspace applications. I took the class this book is written for, taught by the authors. They don’t place emphasis on being able to write assembly, since this is not a useful skill for the majority of programmers. Instead, the goal of this material is to get you to understand assembly and compilation well enough to 1) reverse engineer it if you need to for debugging or security reasons, and 2) be able to write compiler-friendly code, meaning code that can be safely translated into efficient assembly instructions (compilers are conservative, they only optimize when it's certain there's no repercussions).
