今天在x86上有多少指令？ [英] How many instructions are there on x86 today?

问题描述

我正在尝试从旧的386基本指令中学到最新的x86汇编，直到现在为止的所有sse添加。

I am trying to learn up to date x86 assembly all from old 386 base instructions through all the sse additions up until now.

我读了一些类似SSE5计数的内容170条新指令-我被要求让
知道目前总共有多少条指令。

I read some things like SSE5 counts 170 new instructions - and I became urged to know how many of them there are presently in total.

有人可能会说这很难计数（因为有些它们很接近，但是在不同类型的参数上工作），但我认为可以将一些合理的假设计算在内，以便将整数视为一。那么
谁能提供答案吗？

Some may say that it's hard to count (because some of them are close, but work on different type arguments), but I think they can be counted with some reasonable assumptions on how to count multiples as one. So could anybody provide an answer to that?

最好的答案是每个处理器扩展中有多少条指令的表。

The best answer would be the table of how many instructions in each processor extension it was.

推荐答案

在这里看看，此清单应使您了解向每个x86体系结构添加了多少条指令。

Have a look here, this listing should give you an idea on how many instructions were added to each x86 architecture.

在任何情况下，没有比官方英特尔®64和IA-32体系结构软件开发人员手册。

In any case there is no better reference than the official Intel® 64 and IA-32 Architectures Software Developer’s Manual.
