.... which in turn does not change the fact either that modern CPUs (still) have
a dedicated command to compute a square root (and not only that, but also for
trigononetrics and the like), which was a question previously raised, and
answered by me by referring to the x87 FPU instruction set, while at the same
time maintaining that they're not a "naive" hardware implementation.
I still have doubts whether using SSE2 roots/trigonometrics etc. is really
faster than using the FPU, or whether the compiler really does not use them -
at least on 32-bit systems. Note that the deprecation statement relates to
AMD64, not x86 in general as far as I can see.
So again, in what way do your statements invalidate mine?
