+Subject: [PATCH]        * config/rx/rx.h (HAVE_PRE_DECREMENT): Fix typo.
+        * config/rx/rx.c (rx_is_legitimate_constant): Use gcc_unreachable
+        instead of abort.
+        (rx_align_for_label): Test label before extracting its number of
+        uses.
+        (rx_max_skip_for_label): Ignore debug insns.
