ROR (immediate)
Rotate right (immediate).
This instruction is an alias of EXTR.
Syntax
ROR
Wd, Ws, #shift ; 32-bit general registers
Equivalent to EXTR .Wd, Ws, Ws, #shift
ROR
Xd, Xs, #shift ; 64-bit general registers
Equivalent to EXTR .Xd, Xs, Xs, #shift
Where:
Wd-
Is the 32-bit name of the general-purpose destination register.
Ws-
Is the 32-bit name of the general-purpose source register.
shift-
Depends on the instruction variant:
- 32-bit general registers
-
Is the amount by which to rotate, in the range 0 to 31.
- 64-bit general registers
-
Is the amount by which to rotate, in the range 0 to 63.
Xd-
Is the 64-bit name of the general-purpose destination register.
Xs-
Is the 64-bit name of the general-purpose source register.
Operation
Rotate right (immediate) provides the value of the contents of a register rotated by a variable number of bits. The bits that are rotated off the right end are inserted into the vacated bit positions on the left.
Rd = ROR(Rs, shift)RW or X.
