--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The issue for aarch64 with SVE is that MASK_LOAD is not optimized:

  ic = "\x00\x03\x06\t\f\x0f\x12\x15\x18\x1b\x1e!$\'*-";
  ib = "\x00\x03\x06\t\f\x0f\x12\x15\x18\x1b\x1e!$\'*-";
  vect__1.7_9 = .MASK_LOAD (&ib, 8B, { -1, -1, -1, -1, -1, -1, -1, -1, -1, -1,
-1, -1, -1, -1, -1, -1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, ... });
  vect__2.10_35 = .MASK_LOAD (&ic, 8B, { -1, -1, -1, -1, -1, -1, -1, -1, -1,
-1, -1, -1, -1, -1, -1, -1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, ...
});
