Syntax: B {<cond>} <address>
Operation: Jump to specified address
Flags: Unaffected
This instruction is analogous to the BASIC GOTO statement - it makes the processor break off from its normal sequential execution of instructions and jump to a new instruction at a designated location.
When used in conjunction with the normal condition codes, this instruction becomes the basis of conditional branching.
Example:
.loop
SUB R0,R0,#1 ; R0 = R0 - 1
CMP R0,#0 ; is R0 = 0?
BNE loop ; if not, go back to start of loop
Note that a branch forward past 0xFFFFFFFF, or backwards past 0x00000000, is unpredictable.
