https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84005 --- Comment #4 from Alexandre Oliva --- I guess this is a case of adding xfails or target requirements to the dg comments, but I'm not sufficiently familiar with the various vector-related pseudo-target names to tell which ones would be right,

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84005 --- Comment #3 from Alexandre Oliva --- With the current vect alignment computations, we end up using the alignment of the arrays, so on x86_64 it's 256bits (DATA_ALIGNMENT bumps the alignment up) and on ppc64 it's 32bits, no alignment bump.
