MVN Bitwise NOT This instruction writes the bitwise inverse of a register value to the destination register. 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. ORN (shifted register) 0 1 0 1 0 1 0 1 1 1 1 1 1 0 MVN <Wd>, <Wm>{, <shift> #<amount>} ORN <Wd>, WZR, <Wm>{, <shift> #<amount>} Unconditionally 1 MVN <Xd>, <Xm>{, <shift> #<amount>} ORN <Xd>, XZR, <Xm>{, <shift> #<amount>} Unconditionally <Wd> Is the 32-bit name of the general-purpose destination register, encoded in the "Rd" field. <Wm> Is the 32-bit name of the general-purpose source register, encoded in the "Rm" field. <shift> Is the optional shift to be applied to the final source, defaulting to LSL and shift <shift> 00 LSL 01 LSR 10 ASR 11 ROR <amount> For the 32-bit variant: is the shift amount, in the range 0 to 31, defaulting to 0 and encoded in the "imm6" field. <amount> For the 64-bit variant: is the shift amount, in the range 0 to 63, defaulting to 0 and encoded in the "imm6" field, <Xd> Is the 64-bit name of the general-purpose destination register, encoded in the "Rd" field. <Xm> Is the 64-bit name of the general-purpose source register, encoded in the "Rm" field.
