Instruction
Branch range
Bcond label
(inside IT block)
#16 MB to +16 MB
BL{cond} label
#16 MB to +16 MB
BX{cond} Rm
Any value in register
BLX{cond} Rm
Any value in register
Note
You might have to use the .W suffix to get the maximum branch range. See
3.9.1.3 Restrictions
The restrictions are:
do not use PC in the BLX instruction
for BX and BLX, bit[0] of Rm must be 1 for correct execution but a branch occurs to the target address
created by changing bit[0] to 0
when any of these instructions is inside an IT block, it must be the last instruction of the IT block.
Note
Bcond
is the only conditional instruction that is not required to be inside an IT block.
However, it has a longer branch range when it is inside an IT block.
3.9.1.4 Condition flags
These instructions do not change the flags.
3.9.1.5 Examples
B
loopA
; Branch to loopA
BLE
ng
; Conditionally branch to label ng
B.W
target ; Branch to target within 16MB range
BEQ
target ; Conditionally branch to target
BEQ.W
target ; Conditionally branch to target within 1MB
BL
funC
; Branch with link (Call) to function funC, return address
; stored in LR
BX
LR
; Return from function call
BXNE
R0
; Conditionally branch to address stored in R0
BLX
R0
; Branch with link and exchange (Call) to a address stored
; in R0
3.9.2 CBZ and CBNZ
Compare and Branch on Zero, Compare and Branch on Non#Zero.
3.9.2.1 Syntax
CBZ Rn, label
CBNZ Rn, label
where:
Rn
is the register holding the operand.
label
is the branch destination.
