3.9.1 B, BL, BX, and BLX
Branch instructions.
3.9.1.1 Syntax
B{cond} label
BL{cond} label
BX{cond} Rm
BLX{cond} Rm
where:
B
is branch (immediate).
BL
is branch with link (immediate).
BX
is branch indirect (register).
BLX
is branch indirect with link (register).
cond
is an optional condition code, see Section 3.3.7 (p. 43) .
label
is a PC#relative expression. See Section 3.3.6 (p. 42) .
Rm
is a register that indicates an address to branch to. Bit[0] of the value in Rm must be 1, but the
address to branch to is created by changing bit[0] to 0.
3.9.1.2 Operation
All these instructions cause a branch to label, or to the address indicated in Rm. In addition:
The BL and BLX instructions write the address of the next instruction to LR (the link register, R14).
The BX and BLX instructions cause a UsageFault exception if bit[0] of Rm is 0.
Bcond
label
is the only conditional instruction that can be either inside or outside an IT block. All
other branch instructions must be conditional inside an IT block, and must be unconditional outside the
IT block, see Section 3.9.3 (p. 76) .
Table 3.12 (p. 74) shows the ranges for the various branch instructions.
