There was some discussion about this in the last thread about enabling
hardfloat for PPC. See the thread:

However in short the problem is if the float_flag_inexact is clear you
must use softfloat so you can properly calculate the inexact status. We
can't take advantage of the inexact stickiness without loosing the
fidelity of the calculation.
