--- Comment #3 from Bill Schmidt <wschmidt at gcc dot gnu.org> --- For the original test case, send me the results of -ftree-dump-vect-details for P8 BE and I can verify whether this looks like the right fix. Would like to get signoff from Bin on that as well, of course, as this will affect other target architectures.
