X86 INSTRUCTIONS:::CONTROL FLOW:::JUMP INSTRUCTION:::ENTER AND LEAVE

Syntax 1 : enter arg Creates a stack frame with the specified amount of space allocated on the stack. Syntax 2 : leave Destroys the current stack frame, and restores the previous frame. Using Intel syntax this is equivalent to: Syntax 3 : mov esp, ebp pop ebp This will set EBP and ESP to their respective value before the function prologue began therefore reversing any modification to the stack that took place during the prologue.
