It's just that the documentation tells you not to use the x87.Yes, because it's strange programming model should be really dropped.
Agree, but the 80 bit support makes some people want to use it. And that will stay this way until CPU manufacturers invent an alternative.
By the way, recent GCC versions calculate the goniometric functions in software using SSE3, and I checked that this is indeed slightly faster than the x87. So we can get rid to the x87 stuff, should we want.
