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
  • proposal: cmd/compile: define register-based calling convention golang/go#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
