As with all the processor retrospective series, I’m going to focus on how Windows NT used the Intel 80386 in user mode because the original audience for all of these discussions was user-mode developers trying to get up to speed debugging their programs. Normally, this means that I omit instructions that you are unlikely to see in compiler-generated code. However, I’ll set aside a day to cover some of the legacy instructions that are functional but not used in practice.
