3.9.2.2 Operation
Use the CBZ or CBNZ instructions to avoid changing the condition code flags and to reduce the number
of instructions.
CBZ Rn, label
does not change condition flags but is otherwise equivalent to:
CMP
Rn, #0
BEQ
label
CBNZ Rn, label
does not change condition flags but is otherwise equivalent to:
CMP
Rn, #0
BNE
label
3.9.2.3 Restrictions
The restrictions are:
Rn must be in the range of R0 to R7
the branch destination must be within 4 to 130 bytes after the instruction
these instructions must not be used inside an IT block.
3.9.2.4 Condition flags
These instructions do not change the flags.
3.9.2.5 Examples
CBZ
R5, target ; Forward branch if R5 is zero
CBNZ
R0, target ; Forward branch if R0 is not zero
3.9.3 IT
If-Then condition instruction.
3.9.3.1 Syntax
IT{x{y{z}}} cond
where:
x
specifies the condition switch for the second instruction in the IT block.
y
specifies the condition switch for the third instruction in the IT block.
z
specifies the condition switch for the fourth instruction in the IT block.
cond
specifies the condition for the first instruction in the IT block.
The condition switch for the second, third and fourth instruction in the IT block can be either:
T
Then. Applies the condition cond to the instruction.
E
Else. Applies the inverse condition of cond to the instruction.
Note
It is possible to use AL (the always condition) for cond in an IT instruction. If this is done,
all of the instructions in the IT block must be unconditional, and each of x, y, and z must be
T
or omitted but not E.
