--- Comment #5 from Segher Boessenkool <segher at gcc dot gnu.org> ---
vec_unpack* works on vectors of signed integers only, not unsigned.
You need to target at least power8 (-mcpu=power8) to get the long long
versions of this, i.e. the vpkudum and vupk[hl]sw instructions.
This is all documented correctly, as far as I see? In the ISA doc,
in the ABI doc, and in the GCC docs? (Power8 is ISA 2.07, we could add
some clarification for that).
