where:
The range of shift length depends on the instruction:
ASR — shift length from 1 to 32
LSL — shift length from 0 to 31
LSR — shift length from 1 to 32.
Remark: MOVS Rd, Rm is a pseudonym for LSLS Rd, Rm, #0.
ASR, LSL, LSR, and ROR perform an arithmetic-shift-left, logical-shift-left,
logical-shift-right or a right-rotation of the bits in the register Rm by the number of places
specified by the immediate imm or the value in the least-significant byte of the register
specified by Rs.
For details on what result is generated by the different instructions, see
Section
In these instructions, Rd, Rm, and Rs must only specify R0-R7. For non-immediate
instructions, Rd and Rm must specify the same register.
These instructions update the N and Z flags according to the result.
The C flag is updated to the last bit shifted out, except when the shift length is 0, see
Section
Compare and Compare Negative.
Rd is the destination register. If Rd is omitted, it is assumed to take the same value as
Rm.
Rm is the register holding the value to be shifted.
Rs is the register holding the shift length to apply to the value in Rm.
imm is the shift length.
ASRS
20–20.4.3.3.
20–20.4.3.3. The V flag is left unmodified.
LSLS

RORS
R7, R5, #9 ; Arithmetic shift right by 9 bits
All information provided in this document is subject to legal disclaimers.
R1, R2, #3 ; Logical shift left by 3 bits with flag update
R4, R5, #6 ; Logical shift right by 6 bits
R4, R4, R6 ; Rotate right by the value in the bottom byte of R6.
