WebAug 24, 2024 · In normal asm terminology, we'd say that call foo pushes a return address onto the stack. And that ret pops it off (into the program counter / instruction pointer). So yes, call needs to push the return address where execution should resume, not its own address. That address is the byte following the last byte of the call instruction, i.e. the … The program counter (PC), commonly called the instruction pointer (IP) in Intel x86 and Itanium microprocessors, and sometimes called the instruction address register (IAR), the instruction counter, or just part of the instruction sequencer, is a processor register that indicates where a computer is in its program sequence. Usually, the PC is incremented after fetching an instruction, and holds the mem…
