堆栈指针给出的是当前堆栈框架的结束位置。
The stack pointer tells you where the end of your current stack frame is.
这会保存原来的堆栈指针，并自动分配堆栈内存。
This will save the old stack pointer and allocate stack memory atomically.
在Linux - x86平台上的堆栈指针可以实现为。
Getting the stack pointer on Linux-x86 can be implemented as.
如何存储在堆栈指针寄存器值记忆（8085）?。
How to Store value in Stack Pointer Register to Memory (8085)?
在Solaris，下面这段示例代码让您可以获取堆栈指针。
On Solaris, this sample code allows you to get the stack pointer.
堆栈指针损坏。
堆栈指针根本不能这样使用，改变它的值是无意义的。
The stack pointer is not used at all in the function and changing its value is meaningless.
这取决于平台abi；通常在一组指定的寄存器或从“堆栈指针”以固定偏移量。
It depends on the platform ABI; generally either in a designated set of registers or at fixed offsets from a "stack pointer".
longjmpx和 frr_add内核服务可以维护AMR 和上下文堆栈指针。
The setjmpx and longjmpx kernel services maintain the AMR and the context stack pointer.
如果一个函数正在执行，那么堆栈指针就会指向整个堆栈的顶部，这也是该函数活动记录的顶部。
If a function is executing, then the stack pointer is pointing to the top of the whole stack, which is also the top of that function's activation record.
这对函数了解自己的活动记录在什么地方提供了方便——它们可以使用堆栈指针的形式简单地进行定义。
This makes it easy for functions to know where their activation record is — they are simply defined in terms of the stack pointer.
函数可以自由使用288字节的内存，对于不调用其他函数的函数来说，这段内存物理上在堆栈指针之下。
Functions are free to use the 288 bytes that are physically below the stack pointer for functions that do not call other functions.
专用寄存器是那些有预定义的永久功能的寄存器，例如堆栈指针(寄存器1)和TOC指针(寄存器2)。
Dedicated registers are registers that have a predefined, permanent function, like the stack pointer (register 1) and the TOC pointer (register 2).
因为在堆栈中压入一个变量会让堆栈指针移动一个双字，所以给堆栈指针加4(双字的大小)(第32行)。
Since pushing a variable essentially moves the stack pointer by a dword, the stack pointer is adjusted by adding 4 (the size of a dword) to it (line 32).
在堆栈指针上加上双字变量的大小(即esp +12、esp + 16等等)，就可以访问所有后续参数。
All subsequent arguments are accessed by adding the size of a dword variable to the stack pointer (that is, esp + 12, esp + 16, and so on).
因此，使用简化ABI 的函数实际上可以通过从堆栈指针开始的负偏移量来保存、使用和恢复非易失性寄存器。
Therefore, functions using the simplified ABI actually can save, use, and restore non-volatile registers by using negative offsets from the stack pointer.
堆栈常常在函数调用中用于存储本地参数，但在函数中，由于存储在堆栈中的值使得堆栈指针的值常常会发生变化。
The stack is used during a function call to store local arguments. But in the function, the stack pointer may change because values are stored on the stack.
所以您只需通过使用ai $sp, $sp, FRAME_SIZE 将堆栈框架大小加到堆栈指针来移动堆栈指针即可。
So you simply need to move the stack pointer by adding the stack frame size to the stack pointer using ai $sp, $sp, FRAME_SIZE.
此中初始化包括：调解堆栈指针、需要使用的内部数据存储器的初始化、设置数控电源的开机输出电压以及CPU中断部分设置。
Initialized which include: adjusted stack pointer, the need to use the internal data memory of the initialization, set up the boot nc power output voltage and CPU interruption of the set.
因为结构，也就是通常所说的值类型，可以被用在堆栈里，并不能总是为它们创建一个指针。
Because structures, also known as value types, can appear on the stack, it is not always possible to create a pointer to them.
当我们在应用程序中单击的时候，新的事件将被压入堆栈顶部，指针指向最后添加的元素。
As we click around in the application, new events will be pushed onto the top of the stack, and the pointer will identify the last element added.
前面已经讨论了堆栈(数组)和指针。
We've already discussed the stack (an array), and the pointer.
如果内核编译期间设置了CONFIG_FRAME _ POINTER选项，那么就用帧指针寄存器来维护堆栈，从而就可以正确地执行堆栈回溯。
If the CONFIG_FRAME_POINTER option was set during kernel compilation, the frame pointer register is used to maintain stacks and, hence, the stack traceback can be performed correctly.
每个堆栈框架都有一个指向前一个堆栈框架的指针(称为回链指针)，还有一个当它调用其他函数时用于存放返回地址的空间。
Each stack frame holds a pointer to the previous stack frame (called the back chain pointer), as well as a space for return addresses for when it calls other functions.
这样将保护程序代码避免堆栈、缓冲区和函数指针溢出，而且全都不需重新编译。
This protects against stack, buffer, and function pointer overflows, all without recompilation.
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。
Working in conjunction with our stack, we'll have a pointer that identifies our current position in the stack.
这将产生更好的堆栈回溯，因为帧指针寄存器被用作帧指针而不是通用寄存器。
This will lead to better stack tracebacks, as the frame pointer register is used as a frame pointer rather than a general purpose register.
堆栈也在页面上显示，指针标记的当前记录用粗体显示。
The stack will be displayed on the page, and the item identified by the current pointer will be highlighted in bold.
回链指针指向前一个堆栈框架的回链指针。
The back chain pointer points to the back chain pointer of the previous stack frame.
回链指针指向前一个堆栈框架的回链指针。
The back chain pointer points to the back chain pointer of the previous stack frame.
