+       * dbgcnt.def (sms_sched_loop): New counter.
+       * modulo-sched.c: Use sms_sched_loop instead of
+       MAX_SMS_LOOP_NUMBER to determine the maximum number of loops to
+       perform swing modulo scheduling on.  Include dbgcnt.h.
+       * Makefile.in: Add DBGCNT_H to modulo-sched.o.
+       * params.def: Remove PARAM_MAX_SMS_LOOP_NUMBER.

        * config/i386/i386.md (X87MODEF12, SSEMODEF): Remove mode iterators.
