MOV (inverted wide immediate) -- A64

Move (inverted wide immediate) moves an inverted 16-bit immediate value to a register.

is equivalent to

MOVN <Wd>, #<imm16>, LSL #<shift>

and is the preferred disassembly when !(IsZero(imm16) && hw != '00') && !IsOnes(imm16).

is equivalent to

MOVN <Xd>, #<imm16>, LSL #<shift>

and is the preferred disassembly when !(IsZero(imm16) && hw != '00').

<Wd>	Is the 32-bit name of the general-purpose destination register, encoded in the "Rd" field.

<imm>	For the 32-bit variant: is a 32-bit immediate, the bitwise inverse of which can be encoded in "imm16:hw", but excluding 0xFFFF0000 and 0x0000FFFF
	For the 64-bit variant: is a 64-bit immediate, the bitwise inverse of which can be encoded in "imm16:hw".

<Xd>	Is the 64-bit name of the general-purpose destination register, encoded in the "Rd" field.

The description of MOVN gives the operational pseudocode for this instruction.

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.
