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

问题描述

我正在尝试从旧的 386 基本指令到迄今为止的所有 sse 添加来学习最新的 x86 汇编.

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

我读了一些东西，比如 SSE5 计算了 170 条新指令——然后我变成了强烈要求知道目前总共有多少个.

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.

有些人可能会说很难计算(因为它们中的一些很接近，但适用于不同类型的参数)，但我认为可以通过一些关于如何将倍数计算为一的合理假设来计算它们.也可以有人提供答案吗?

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指令的表格.

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

推荐答案

看看这里，这个清单应该能让你了解每个 x86 架构添加了多少指令.

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

无论如何，没有比官方 英特尔® 64 位和 IA-32 架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.
