Title: Ask HN: Which books/resources to understand modern Assembler?
问HN：哪些书籍/资源可以理解现代汇编？
Text: I’d like to learn more about Assembler in order to be able to work with LLVM and JIT as well as to write high performance low-level code. I’m familiar with the basics of x86 but I haven’t touched Assembler in a while, so I’m wondering which resources and in particular books you’d recommend?
我想了解更多关于汇编程序的知识，以便能够使用LLVM和JIT以及编写高性能的低级代码。我熟悉x86的基础知识，但我已经有一段时间没有接触过Assembler了，所以我想知道你会推荐哪些资源，尤其是书籍？Url:

It might help you to do the same – the timed game aspect forces you to learn to read the instructions quickly.<p>The game is like Tetris, but the blocks are ARM assembly instructions. As instructions fall, you can change the operand registers. Locking instructions into the .text section executes them in a CPU emulator running client-side in the browser, so you can immediately see the effects of every action. Your score is stored in memory at the address pointed to by one of the registers, so even though you earn points for each instruction executed without segfaulting, the true goal is to execute instructions that directly change the memory containing the score value.<p>When I released it a bit less than a year ago, I posted it to Hacker News as a Show HN:<p><a href="https://news.ycombinator.com/item?id=37083309">https://news.ycombinator.com/item?id=37083309</a>

chc4: IMO You should just stick some programs in Ghidra/Godbolt and see what they emit, especially for small individual snippets whenever you think "I want to do X, what's the best way of doing it". There really isn't much difference between "baby's first assembly" program, where you just have movs and like five other common instructions, and the kind of assembly an optimizing compiler emits: it's a matter of recognizing that some operations can be merged into a more specialized one or the addressing mode of another, or you can use a setcc with a results flag from something you already computed, or what have you. The good code that LLVM and JITs emit for the most part aren't due to much better instruction selection but due to much better optimization passes, which learning more about assembly doesn't help with: it's about transforming code in general at a high level, which you would do at the compiler IR step before touching assembly at all.

jmspring: Under no circumstances should knowledge of Assembler be needed to work with LLMs.<p>Many people that work in DS/ML can barely make it with Python.
