The Art of 64-bit Assembly | Hacker News

A Hacker News thread about a Windows-focused 64-bit assembly book sparked debate over how well AI can explain low-level code.

Commenters argued that specialized technical books may train models better than generic corpora, while tools like RAG still have clear limits.

The discussion also focused on the need for better abstractions, preprocessors, and compiler-like tooling to make assembly safer and more portable.

Performance topics included register management, branch prediction, handwritten assembly gains, and x86-64-specific tuning.
