--- Comment #1 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
Why integer-compare? Floating-point equality check does not raise "invalid"
with qNaN inputs, so why not set (or clear) the sign bit and then
compare-equals against negative (or positive, respectively) infinity?

(which is what Clang does)
