--- Comment #8 from ktkachov at gcc dot gnu.org ---
After playing around with this I believe the problem is in the
*neon_mov<mode> pattern in the arm backend. The way it constructs the
const_vector of {1, 0, 1, ... } is probably wrong for big-endian.
If I disable alternative 2 of that pattern (forcing a constant pool load
instead) the testcase runs correctly. I'll see if I can come up with a fix
