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.
, where R
d = R
n OR NOT shift
(R
m, amount
)
is either R
W
or X
.
