How many x86 instructions?
I was asked this question recently, and I just realized that I really
don't know the answer to this. I may have known at one time, but I don't anymore, as things have moved on since I last used to do assembly programming. How many instructions are there in modern x86 processors? These days it seems more practical to just list the number of x86 instruction set extensions than to count up just the individual instructions themselves. But even the number of x86 instruction set extensions are becoming unmanageable: x86-16, x86-32, x64, x87, MMX, SSE, 3DNow, VT-X, AMD-V, AVX, AES, etc., etc. I searched around just looking for a simple count of instructions, and I couldn't find them.
