--- Comment #16 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I suspect this patch will fix the arm failure:

Arm enables -funsafe-math-optimizations for the vector testsuite (as it
requires because of denormals IIRC) but this testcase requires strict ordering
so you need to not allow `-funsafe-math-optimizations` which is what
vect_float_strict does.
