Yeah, I looked at some of those sites already, and that was my
impression too, that the instructions aren't easy to count. It doesn't
help that Intel and AMD have their own extensions, either.

But it goes to show why the age of compilers is well and truly upon us,
there's no human way to keep track of these machine language
instructions. Compilers just use a subset, and just repeat those
instructions over and over again.
