ORN (shifted register)

Bitwise OR NOT (shifted register).

This instruction is used by the alias MVN.

Syntax

ORN Wd, Wn, Wm{, shift #amount} ; 32-bit general registers

ORN Xd, Xn, Xm{, shift #amount} ; 64-bit general registers

Where:

Wd

Is the 32-bit name of the general-purpose destination register.

Wn

Is the 32-bit name of the first general-purpose source register.

Wm

Is the 32-bit name of the second general-purpose source register.

amount

Depends on the instruction variant:

32-bit general registers

Is the shift amount, in the range 0 to 31, defaulting to 0.

64-bit general registers

Is the shift amount, in the range 0 to 63, defaulting to 0.

Xd

Is the 64-bit name of the general-purpose destination register.

Xn

Is the 64-bit name of the first general-purpose source register.

Xm

Is the 64-bit name of the second general-purpose source register.

shift

Is the optional shift to be applied to the final source, defaulting to LSL, and can be one of LSL, LSR, ASR, or ROR.

Operation

Bitwise OR NOT (shifted register) performs a bitwise (inclusive) OR of a register value and the complement of an optionally-shifted register value, and writes the result to the destination register.

Rd = Rn OR NOT shift(Rm, amount), where R is either W or X.
