一起来学 x86-64 汇编
Let's Learn x86-64 Assembly (2020)

导读
这是一篇 x86-64 汇编入门教程的第一部分，作者从最小可运行的程序讲起，逐步介绍寄存器、指令和工具链；从评论看，后续内容还涉及 Windows 的 PE 格式和 DLL 导入等话题。全文以纯文本网页形式发布，偏 Windows 视角，结构跨度较大。
为什么经久不衰：汇编和机器层的知识十几年不变，想真正理解 CPU 与程序的执行方式，这类从零手写的教程始终是难以替代的入口。

x86 太杂乱不适合入门，建议从 ARM 或写模拟器起步，并质疑教程后半段跑题到 PE 格式。
很多人用 x86(-64) 入门汇编，但这个指令集混乱、复杂又层层叠加，在我看来始终是糟糕的选择——就像用 C++ 上编程入门课，能理解其现实理由，但弊大于利。我更推荐弄块 ARM/ARM64 开发板从它入手，概念大多可以迁移；为某个简单架构写一个 CPU 模拟器再在上面编程也是很好的教学方式。另外这篇教程结构有点怪：从 “int3 ret” 直接跳到“PE 格式与 DLL 导入”，跨度太大，而且未必与学汇编强相关。

It's very common for people to learn assembly using x86(-64) but this ISA is so messy, complicated and layered that it always seems like the bad choice to me. It's like teaching an intro programming course using C++, I understand why it's practical but it seems like it will be more trouble than it's worth. I'd probably recommend getting some ARM or ARM64 board and starting with this, most of the concepts will carry over to other assemblies anyway. Writing a simple CPU emulator for some simple architecture and then coding on it can also be a great teaching experience, if a little more involved. I find this tutorial a bit oddly structured too, but that may be because I'm from un*x world and I don't have the Windows mindset. It basically goes from "int3 ret" to "The PE Format and DLL Imports". That seems like quite the jump, and not necessarily super relevant to learning ASM IMO.
用移植 JonesForth 这种小而完整的项目来练 x86-64，是很有收获的学习方式。
我最近挑战把 JonesForth 移植到 x86-64，这是很久以来最有收获的个人项目之一：我能写 x86-64 而不必先搭一个完整应用，过程中顺带学 Forth 更有趣。我知道已有 jonesforth64，但自己动手移植完全值得。

I recently took up the challenge of porting JonesForth to x86-64. It was one of the most rewarding personal challenges in a very long time. For one, I was able to write x86-64 without needing to whip up a complete application. And learning Forth during the process was even more fun. https://github.com/mlang/jonesforth And yes, I know there is also jonesforth64. However, doing the porting myself was totally worth it.
指出原文一处错误：ah/bh/ch/dh 是第 8-15 位，而非“高 8 位”。
> 另外，rax、rbx、rcx、rdx 的高 8 位可以称为 ah、bh、ch、dh。 那是第 8 到第 15 位（最低位为 0、最高位为 63），不是最高的 8 位。没时间读全文，但看起来不错。

> Additionally, the higher 8 bits of rax, rbx, rcx and rdx can be referred to as ah, bh, ch and dh. That’s bits 8-15 (lowest being 0 and highest being 63), not the highest 8 bits Didn’t have time to read the whole thing, but it looks nice.
称赞页面深色主题的对比度处理得当、阅读舒适。
完全跑题，但必须说：这是少数把深色背景浅色文字做得好的网页之一。对比度控制得当，文字可读，不用切到阅读模式或戴墨镜。希望那些用惨白字配纯黑底的网站学学。

Completely off topic, but I just have to say it: This is one of the few light-text-on-dark-background web pages that actually does it well. Contrast is managed so the text is still readable without escaping to Reader View or wearing sunglasses. I wish those sites that use squeaky-white on pitch-black would take example of this.
