--- Comment #6 from Michael Meissner <meissner at gcc dot gnu.org> ---
Note, in the first comment, I mis-read the instruction, and the instruction
being used is vector unsigned long long rotate left, and not vector unsigned
long long shift left.

I.e.:

                                        Trunk   GCC14   GCC13   GCC12   GCC11
                                        -----   -----   -----   -----   -----
Vector rotate right                       696     696     696     696     696
