--- Comment #1 from Segher Boessenkool <segher at gcc dot gnu.org> ---
This is not a bug.
Please read the second programming note for xvcvdpsxws in ISA 3.1:
Previous versions of the architecture allowed the contents of words 1
and 3 of the result register to be undefined. However, all processors
that support this instruction write the result into words 0 and 1 and
words 2 and 3 of the result register, as is required by this version
of the architecture.
It sounds like QEMU needs fixing to behave like all hardware does?
