--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
/* For Advanced SIMD we can create an integer with only the top bit set
using fneg (0.0f). */
is wrong in aarch64_maybe_generate_simd_constant.
it should use either an unspec here or an XOR instead of fneg here I think
especially for -ffast-math reasons.
