where:
op is one of:
S is an optional suffix. If S is specified, the condition code flags are updated on the result
of the operation, see
Rd is the destination register.
Rm is the register holding the shift length to apply to the value in Rm. Only the least
significant byte is used and can be in the range 0 to 255.
Rs s the register holding the shift length to apply to the value in Rm. Only the least
significant byte is used and can be in the range 0 to 255.
n is the shift length. The range of shift length depends on the instruction:
Remark: MOV{S}{cond} Rd, Rm is the preferred syntax for LSL{S}{cond} Rd, Rm, #0.
ASR, LSL, LSR, and ROR move the bits in the register Rm to the left or right by the number of
places specified by constant n or register Rs.
RRX moves the bits in register Rm to the right by 1.
In all these instructions, the result is written to Rd, but the value in register Rm remains
unchanged. For details on what result is generated by the different instructions, see
Section 34.2.3.4 “Shift
Do not use SP and do not use PC.
ASR: Arithmetic Shift Right.
LSL: Logical Shift Left.
LSR: Logical Shift Right.
ROR: Rotate Right.
ASR: shift length from 1 to 32
LSL: shift length from 0 to 31
LSR: shift length from 1 to 32
ROR: shift length from 1 to 31
