3.5.2.4 Condition flags
If S is specified, these instructions:
update the N and Z flags according to the result
can update the C flag during the calculation of Operand2, see Section 3.3.3 (p. 38)
do not affect the V flag.
3.5.2.5 Examples
AND
R9, R2, #0xFF00
ORREQ
R2, R0, R5
ANDS
R9, R8, #0x19
EORS
R7, R11, #0x18181818
BIC
R0, R1, #0xab
ORN
R7, R11, R14, ROR #4
ORNS
R7, R11, R14, ASR #32
3.5.3 ASR, LSL, LSR, ROR, and RRX
Arithmetic Shift Right, Logical Shift Left, Logical Shift Right, Rotate Right, and Rotate Right with Extend.
3.5.3.1 Syntax
op{S}{cond} Rd, Rm, Rs
op{S}{cond} Rd, Rm, #n
RRX{S}{cond} Rd, Rm
where:
op
is one of:
ASR
Arithmetic Shift Right.
LSL
Logical Shift Left.
LSR
Logical Shift Right.
ROR
Rotate Right.
S
is an optional suffix. If S is specified, the condition code flags are updated on the result of the
operation, see Section 3.3.7 (p. 43) .
Rd
is the destination register.
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. 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:
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.
Note
MOV{S}{cond} Rd, Rm
is the preferred syntax for LSL{S}{cond} Rd, Rm, #0.
3.5.3.2 Operation
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.
