if the result of an addition is greater than or equal to 2
32
if the result of a subtraction is positive or zero
as the result of an inline barrel shifter operation in a move or logical instruction.
Overflow occurs if the result of an add, subtract, or compare is greater than or equal to 2
31, or less
than –2
31.
Note
Most instructions update the status flags only if the S suffix is specified. See the instruction
descriptions for more information.
3.3.7.2 Condition code suffixes
The instructions that can be conditional have an optional condition code, shown in syntax descriptions
as {cond}. Conditional execution requires a preceding IT instruction. An instruction with a condition
code is only executed if the condition code flags in the APSR meet the specified condition. Table 3.4 (p.
44) shows the condition codes to use.
You can use conditional execution with the IT instruction to reduce the number of branch instructions
in code.
Table 3.4 (p. 44) also shows the relationship between condition code suffixes and the N, Z, C, and
V flags.
Table 3.4. Condition code suffixes
Suffix
Flags
Meaning
EQ
Z = 1
Equal
NE
Z = 0
Not equal
CS or
HS
C = 1
Higher or same, unsigned #
CC or
LO
C = 0
Lower, unsigned <
MI
N = 1
Negative
PL
N = 0
Positive or zero
VS
V = 1
Overflow
VC
V = 0
No overflow
HI
C = 1 and Z = 0
Higher, unsigned >
LS
C = 0 or Z = 1
Lower or same, unsigned #
GE
N = V
Greater than or equal, signed #
LT
N != V
Less than, signed <
GT
Z = 0 and N = V
Greater than, signed >
LE
Z = 1 and N != V
Less than or equal, signed #
AL
Can have any value
Always. This is the default when no suffix is specified.
Example 3.1 (p. 44) shows the use of a conditional instruction to find the absolute value of a number.
R0
= ABS(R1).
Example 3.1. Absolute value
MOVS
R0, R1
; R0 = R1, setting flags
IT
MI
; IT instruction for the negative condition
RSBMI
R0, R1, #0
; If negative, R0 = -R1
