3.5.5 CMP and CMN
Compare and Compare Negative.
3.5.5.1 Syntax
CMP{cond} Rn, Operand2
CMN{cond} Rn, Operand2
where:
cond
is an optional condition code, see Section 3.3.7 (p. 43) .
Rn
is the register holding the first operand.
Operand2
is a flexible second operand. See Section 3.3.3 (p. 38) for details of the options.
3.5.5.2 Operation
These instructions compare the value in a register with Operand2. They update the condition flags on
the result, but do not write the result to a register.
The CMP instruction subtracts the value of Operand2 from the value in Rn. This is the same as a SUBS
instruction, except that the result is discarded.
The CMN instruction adds the value of Operand2 to the value in Rn. This is the same as an ADDS
instruction, except that the result is discarded.
3.5.5.3 Restrictions
In these instructions:
do not use PC
Operand2 must not be SP.
3.5.5.4 Condition flags
These instructions update the N, Z, C and V flags according to the result.
3.5.5.5 Examples
CMP
R2, R9
CMN
R0, #6400
CMPGT
SP, R7, LSL #2
3.5.6 MOV and MVN
Move and Move NOT.
3.5.6.1 Syntax
MOV{S}{cond} Rd, Operand2
MOV{cond} Rd, #imm16
MVN{S}{cond} Rd, Operand2
