可有人请向我解释（简单来说）的ESP之间的差异，EBP，和ESI寄存器是什么？ [英] Can someone please explain to me (in very simple terms) what the difference between the esp, ebp, and esi register is?

问题描述

我必须学习汇编，我以什么不同的寄存器做/点很困惑。

I've got to learn assembly and I'm very confused as to what the different registers do/point to.

推荐答案

在某些架构，据我所知，所有的寄存器都是平等的，并没有真正超越寄存器的名字没有区别。在x86上可以主要用于通用计算的任何寄存器，但一些寄存器被隐式绑定指令集。

On some architectures, AFAIK, all registers are created equal, and there is really no difference beyond the name of the register. On x86 you can mostly use any registers for general-purpose computing, but some registers are implicitly bound to the instruction set.

关于特殊用途的寄存器的信息很多都可以在这里找到 。

Lots of information about special purposes for registers can be found here.

例如：

• EAX ，蓄电池：许多运算指令隐含在 EAX
运行

• EDX 数据：<$ C：算术操作隐含的64位值 EDX 操作$ C> EAX


• ECX ，计数器：循环隐递减 ECX


• ESI ，源指标：一些字符串操作读一个字符串从内存指向 ESI


• EDI ，目标索引：一些字符串操作写一个字符串到内存指向 EDI


• EBP ，基指针：通常用来指向局部变量


• 尤其，堆栈指针：指向堆栈的顶部，由推，<$ C隐含使用$ C>弹出，呼叫和 RET

• eax, accumulator: many arithmetic instructions implicitly operate on eax
• edx, data: some arithmetic operations implicitly operate on the 64-bit value in edx:eax
• ecx, counter: loop implicitly decrements ecx
• esi, source index: some string operations read a string from the memory pointed to by esi
• edi, destination index: some string operations write a string to the memory pointed to by edi
• ebp, base pointer: normally used to point to local variables
• esp, stack pointer: points to the top of the stack, used implicitly by push, pop, call and ret

x86指令集是一个复杂的野兽，真的。许多指令都有隐含的使用一个寄存器或其他形式的更短。一些寄存器可以用来做一定的处理，有些则不能。

The x86 instruction set is a complex beast, really. Many instructions have shorter forms that implicitly use one register or another. Some registers can be used to do certain addressing while others cannot.

借助英特尔公司的80386程序员参考手册是一个不可替代的资源，它基本上告诉你一切有了解x86汇编，除了较新的扩展。

The Intel 80386 Programmer's Reference Manual is a irreplaceable resource, it basically tells you everything there is to know about x86 assembly, except for newer extensions.

借助 PC大会（五）本书是学习汇编很好的资源。

The PC Assembly (e)book is a great resource for learning assembly.
