x86和x64体系结构的汇编语言之间有什么区别? [英] What is the difference between assembly language of x86 and x64 architecture?

问题描述

我正在此处学习这本书.现在，它反复说要使用x86处理器，因为其源代码基于x86.但是我的笔记本电脑是amd64类型的.所以我想知道有多少区别.我可以继续阅读并理解吗?

I am studying this book here . Now it says repeatedly to use a x86 processor cause its source code's are based on x86. But My laptop is of type amd64 . So I want to know how much is the difference. Can I continue reading the book and understand?

推荐答案

实际的64位程序使用不同的指令集(尽管它与家族有很强的相似性).但这不必担心，因为它是向后兼容的:如果您不尝试将其编译为64位代码，那么32位代码就可以正常运行.

Actual 64 bit programs use a different instruction set (though it has a strong family resemblance). But that doesn't need to concern you, as it's backwards compatible: 32 bit code runs just fine, if you don't attempt to compile it as 64 bit code.
