2007-09-09 Revital Eres <eres@il.ibm.com>
* 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.
2007-09-09 Uros Bizjak <ubizjak@gmail.com>
* config/i386/i386.md (X87MODEF12, SSEMODEF): Remove mode iterators.
