Same concepts, even if the target processor is different.

FWIW, I was in a code review this week for a few hundred bytes of assembly code.  The number of people fluent in assembly at the company is very small, but this product sells several hundred thousand units a year and is very important.  The code was in C using a highly optimizing compiler but it couldn’t quite squeeze the code enough once a new feature was added, and going to a slightly larger processor with more RAM (32 bytes) was about four cents more per chip, so switching to assembly was the best approach.

Not all computers have 2 TB disk and 32 GB RAM.  When you need to save a few bytes, assembly is your friend.
