<<bring these variants together. But it looks like the committee stands
to be widely ignored for the next 15 years, just as it has been
ignored for the last 15 years.
That's an absurd overstatement. The fact of the matter is that nearly all
serious numerical computation is done on computers that provide a realization
of IEEE 754, and this would never have been possible without the hard work
of the committee, and indeed early on, no one would have predicted the
enormous success of IEEE 754.
I don't think there are "untold billions" of embedded chips implementing
non-IEEE fpt, but that presumably is idle hyperobole. In fact the majority
of small embedded chips do not support hardware fpt at all.
As for whether gcc should support the native arithmetic of any chip to which
it is ported, of course it should, and yes, indeed, this may involve soe
modifications to the capabilities of gcc in this area.
