I remember studying `Computer Systems: A Programmers Perspective'[1] in my undergrad which was pretty good and covered how programs look in assembly (calling conventions, call frames, data representation, assembly ...). Also, to get better understanding of x86 ISA I followed the old i386 manual[2]. Its old but much more smaller. Perhaps once you feel comfortable, you can move to newer manuals. I never read newer ones (because I never actually needed assembly for any project, was just studying for fun).
