TIL. I had tried to understand it a bit, but felt lost pretty fast, and then eventually found out that’s because it’s huge. Is there a good intro to the basic instructions you’re aware of?
By “play act the compiler” I mean a fairly elaborate system of written notes that significantly exceeds the size of the actual program. Like, it’s no wonder they started thinking about building machine compilers at that stage.
I believe this guide can get you started pretty quickly to get the basics down. There are tons of guides online, but most of them will give you the basics (“this is how to find a prime number”) and then leave you on your own. Once you know how instructions, calling conventions, and system calls work, the rest of assembly programming is just reading documentation or Googling “how do I X in assembly”.
What can help is using websites like godbolt.org to write simple C programs and looking at the compiled output. Look up instructions you don’t recognize and make sure you don’t enable optimizations, unless you want to deal with atrocities like VGF2P8AFFINEINVQB.
If you don’t mind getting started with old assembly, there are also more comprehensive guides for MS-DOS and old Windows that mostly involve 16 bit and 32 bit programs programming. 64 bit programming is different (uses more registers to pass variables, floating point support is guaranteed, etc.) but there aren’t as many good books on the topic anymore now that it’s become a niche.
I think there are quite a few guides out there for ARM these days, if you have something like a Raspberry Pi or an emulator you can also learn ARM assembly (which has fewer supported weird instructions, but also a tonne of weird stuff).
If you want to go deep, you can also check Ben Eater’s youtube channel where he shows step by step how an 8 bit computer on a breadboard works, how instructions relate to memory, and all that. With some intuition from that, learning amd64 assembly may be a lot easier than going from normal programming languages to assembly.
Edit: to get into understanding assembly programming, [Human Resource Machine[(https://store.steampowered.com/app/375820/Human_Resource_Machine/) will explain the concepts of assembly programming without ever overtly explaining the concepts. Plus, it’s a fun puzzle game.
