As an aside: the early 386's POPAD instruction has a famous bug. EAX is written in the RNI (run-next-instruction) delay slot via an indirect register file access -- the only instruction that does this. When the next instruction uses a base+index addressing mode, the register file write from POPAD collides with the EA calculation's register file read, corrupting the address. A fitting example of how complex optimizations can lead to problems.
