Working in conjunction with our stack, we'll have a pointer that identifies our current position in the stack.

与堆栈在一起的还有一个指针，指示我们在堆栈中的当前位置。

Next, the current stack frame pointer is stored as the back pointer for the next stack frame, even though you haven't established the stack frame yet (this is done through negative offsets).

接下来，当前堆栈框架指针会被存储为指向下一个堆栈框架的后向指针，虽然尚未建立堆栈框架(这是通过负的偏移量实现的)。

The stack pointer tells you where the end of your current stack frame is.

堆栈指针给出的是当前堆栈框架的结束位置。
