Yes, if implemented as shown.
You could use intrinsics for the bit casting & so on and it would be well-defined to the extent that those intrinsics are.
(I understand some people consider SIMD intrinsics in general to be UB at language level, in part because they let you switch between floats & ints in a hardware-specific way.)
