x86 Assembly Language Programming
- PC Assembly
Language, Paul A. Carter, November 2003. 188pp. (local PDF copy) (local PDF copy, printed 2 pages per sheet)
A clear description of x86 assembly language and assembly
language in general, including some stuff you hopefully know already.
You might prefer to read this on line, rather than print it out; it's a
quick read. Warning: This book uses "Intel" assembly syntax, in
which instructions are written "
instr dst, src"; we will use
"AT&T" assembly syntax, in which they are written "
dst". You don't need to read the following sections, which will
not be needed for class: 1.3.6-1.3.7, 1.4, 1.5, 5, 6, and 7.2.
Guide to Inline Assembly, Brennan "Bas" Underwood. (local copy)
A short and sweet description of how to use inline assembly
instructions with GCC. Includes a description of the "AT&T" assembly
syntax used by GCC.

- Tool Interface Standard (TIS) Executable and
Linking Format (ELF) Specification, Version
Our kernel runs ELF executables; this is the definitive
standard for how these executables are constructed.

and CPU emulator.
