Yes. That is the reason. Not everything runs on the latest intel platform.
Hah! How times change. But, assuming you were in a situation where you wanted to use the dirty-trick method, is there a way to specify it in C? Maybe inline assembly is the correct way to do that... it would explicitly define the operation and implicitly restrict it to an architecture where it's valid, which is probably what you want anyway.
That's a funny example. What's a safe way to do fast inverse square root?
