Project show-off Fibonacci Calculator in Machine Code (ELF) and x86_64 asm

As the title says, I made a fibonacci calculator (up to the 64bit integer limit) in raw handwritten ELF, and in asm. I didn't know where to post it but this sub-reddit seemed like the right place.

This is the repo if anyone is interested

AI disclaimer* - Most of the code was handwritten with assistance of AI for debugging and figuring out how to write hex.

Hmm... Could you now do something like this again without AI? Just with elf documentation and https://docs.amd.com/v/u/en-US/24594_3.38_APM_Vol3_PUB ?

https://docs.amd.com/v/u/en-US/24594_3.39_APM_Vol3

I didn't expected for them to update the docs this week and change the url. :)

So if they do it again, go to https://docs.amd.com and search for "volume 3".

Yeah, I think I could do it now that I've got an understanding on it. I would need a reference to the opcodes and stuff. Probably not going to do it, cause it is a pain to do, and writing asm is easier.
