Link for x86 functionality instructions

I am looking for a link to the "evolution" of the x86 command set. Basically, what new commands make old teams redundant and unusable, as well as the breakdown of the team according to their functionality, and not the time / processor to which they were added.

In addition, is there a link to the percentage of x86 commands used in developing programs in recent years (which means which commands are no longer used in modern programs)?

This is more like a research question than a programming question.

It’s best to go, say, to a Wikipedia article that lists x86 instructions for processors in the lineup, find out that each instruction executes and classifies them according to functionality.

As for the trends in the use of instructions, I do not know. This is a pretty busy question. This is not much different from asking: "What English words are more common in modern usage?" What instructions are used depends on the application.
