--- Comment #3 from Paul Caprioli <paul at hpkfft dot com> ---
Note that this is not for me; it's for everybody else.
The idea is for this to be the standard macro for specifying the IEEE rounding
to nearest attribute `roundTiesToEven`.

My contacts at Intel tell me they can't change the intrinsics guide until there
is compiler support.   So, it's a chicken-and-egg problem; somebody has to go
first.
It makes sense for the compilers to go first and the documentation to reflect
the improvement only after it is usable.

I hope we can agree that is wrong/misleading (for a human code reviewer) to see
"round to nearest int" when an instruction does not do that (because it returns
a correctly rounded floating point value).
