+
+ The MIPS assembler also automatically adjusts any preceding label.
+
+ The implementation therefore applied the adjustment to a maximum of
+ one label. However, other label adjustments are applied to batches
+ of labels, and adjusting just one caused problems when new labels
+ were added for the sake of debugging or unwind information.
+ We therefore adjust all preceding labels (given as LABELS) instead. */
