-| fpsp_snan --- FPSP handler for signalling NAN exception
-|
-| SNAN for float -> integer conversions (integer conversion of
-| an SNAN) is a non-maskable run-time exception.
-|
-| For trap disabled the 040 does the following:
-| If the dest data format is s, d, or x, then the SNAN bit in the NAN
-| is set to one and the resulting non-signaling NAN (truncated if
-| necessary) is transferred to the dest.  If the dest format is b, w,
-| or l, then garbage is written to the dest (actually the upper 32 bits
-| of the mantissa are sent to the integer unit).
-|
-| For trap enabled the 040 does the following:
-| If the inst is move_out, then the results are the same as for trap
-| disabled with the exception posted.  If the instruction is not move_
-| out, the dest. is not modified, and the exception is posted.
