↑ For modern processors, the concept of "where it is in its sequence" is too simplistic, as instruction-level parallelism and out-of-order execution may occur. ↑ In a processor where the incrementation precedes the fetch, the PC points to the current instruction being executed. In some processors, the PC points some distance beyond the current instruction; for instance, in the ARM7, the value of PC visible to the programmer points beyond the current instruction and beyond the delay slot.[5]
