--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started with r9-1623-gc518c1025b435e1c593a745036fc9b8ed04c5819.
At first I thought it is because of the rs6000.c changes, where previously it
was using 15 in the last two spots, but now "16" like in the earlier cases, but
most likely it is some other change.  Martin, can you please have a look?
