Returns a simd or simd_mask object with the same elements, but a different ABI.

3-6) These functions do not participate in overloading resolution unless N is the same as the size of the return type.

Parameters

v

-

the input simd or simd_mask object

Return value

The simd or simd_mask object with the specified ABI.
