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
ORN
Xd, Xn, Xm{, shift #amount} ; 64-bit
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, orROR.
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)RW or X.
