Example code from Assembly Language Step By Step, Third Edition

This is just a repo to track my experience reading Assembly Language Step By Step, Third Edition..

The code from the book targets Linux for i386 with NASM and I plan to add support for other targets for practice. The instructions assume the usage of an x86_64 Linux.

Planned targets include:

• x86_64 (with NASM/GAS/flat assembler g)
  • GAS
  • NASM
  • flat assembler
• RISC-V 64
• WebAssembly (text format with WASI)

I would also like to use a literate programming tool document my code in the future.

Assemblers/Runtimes used:

• NASM
• QEMU (For RISC-V 64)
• Wasmtime (For WebAssembly text format with WASI)
• Zig (For a cross-platform LLVM assembler and build system)
• flat assembler

Debuggers:

• LLDB
• rr
