Description

While working on the blogos tutorial, I started looking at ABI for function call in different programming languages

Rust does not have stable ABI yet
Go use stack even if everything can fit into register
- https://github.com/golang/go/issues/18597
- https://syslog.ravelin.com/anatomy-of-a-function-call-in-go-f6fc81b80ecc

The post is expected to cover the following

how procedure call is implemented (based on csapp chap3), transfer control, pass parameter etc.
dump asm for different programming languages
a short intro to asm so you can read the dump
return value larger than the rax register (i.e. use stack ...)
specific things about writing handlers in OS, e.g. why interrupt handlers are different
