<Vd>	Is the name of the SIMD&FP source and destination register, encoded in the "Rd" field.

<Vn>	Is the name of the second SIMD&FP source register, encoded in the "Rn" field.

If PSTATE.DIT is 1:

The execution time of this instruction is independent of:
- The values of the data supplied in any of its registers.
- The values of the NZCV flags.
The response of this instruction to asynchronous exceptions does not vary based on:
- The values of the data supplied in any of its registers.
- The values of the NZCV flags.
