The original code checks 'if (ARC_CC_AL)', which is always true since ARC_CC_AL is a constant. This makes the check redundant and likely obscures the intention of verifying whether the jump is conditional. Updates the code to check cond == ARC_CC_AL instead, reflecting the intent to differentiate conditional from unconditional jumps.
