I don't think the following affects the resolution of the ticket, but just for the record, trapping is _not_ an option the ISA permits. The only legal outcome from using an improperly NaN-boxed value as an argument to an instruction that requires NaN-boxed inputs is that the canonical NaN is substituted in its place.
