How does that differ from just using reserved operands (which the
hardware already knows how to fault on)?  Would the simulated FP
include things operationally like infinities or quiet NaNs (presumably
in the form of a subset of reserved operands)?  I don't see how else
software-simulated VAX FP would help.
