Here's another octal x86 reference for comparison: https://justine.lol/blinkenlights/8086.html

Thank you for making that. There are are articles that mention how we forgot the octal connection to the x86 isa. Your ascii art table is just a really clean way of visualizing it.

Oh I'd missed that page on the blinkenlights site. Thanks!

I hope you enjoy it! Since you mentioned chibicc earlier in this thread, and you've written an assembler of your own, this might be of interest to you: https://github.com/jart/cosmopolitan/blob/master/third_party... Your work was brought to my attention maybe a year and a half ago and I think what you're doing is pretty cool. Feel free to reach out by email if there's anything I can do to help.

That's a neat assembler library. Thanks for pointing it out. I have been using maximecb's https://github.com/Shopify/ruby/blob/yjit/yjit_asm.h

Oh that's not intended as a library for things like jit. It's just a program that takes an asm file generated by chibicc and turns it into an ELF .o file. Building a library for x86 codegen would be such a rabbit hole. Intel Xed did that but it was just so huge that the only part I wanted to use was its instruction length decoder.

Here's another interesting one I just noticed:
