LEAVE is the counterpart to ENTER. The ENTER instruction sets up a stack frame by first pushing EBP onto the stack and then copies ESP into EBP, so LEAVE has to do the opposite, i.e. copy EBP to ESP and then restore the old EBP from the stack. NettetPerforms a System Call (SVC). This instruction can only be executed when the CPU is in User mode. The execution of this instruction will: setup the Supervisor stack; push to it the Instruction Pointer (IP) and the user Stack Pointer (SP); switch the CPU to Supervisor mode; and jump to address 0x0006.
