(actual_hazard_this_instance): Remove decl of unused variable I. (actual_hazard): Remove two block-scope decls of unused variable BEST. (sched_analyze_1): Remove decls of unused variables OFFSET and BIT. (sched_analyze): Remove decl of unused variable DEST. (sched_note_set): Remove decl of unused variable J. (create_reg_dead_note): Remove decl of unused variable BACKLINK. (new_sometimes_live): Remove decl of unused variable I. (schedule_block): Remove decls of unused variables LAST_NOTE and REGNO. (schedule_insns): Remove decls of unused variables I and INSNS. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@6893 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/sched.c | 19 ++++--------------- 1 file changed, 4 insertions(+), 15 deletions(-) (limited to 'gcc/sched.c') diff --git a/gcc/sched.c b/gcc/sched.c index 56ad42ce1d0..1e22650fa9d 100644 --- a/gcc/sched.c +++ b/gcc/sched.c @@ -1170,8 +1170,6 @@ static int unit_n_insns[FUNCTION_UNITS_SIZE]; static void clear_units () { - int unit; - bzero (unit_last_insn, sizeof (unit_last_insn)); bzero (unit_tick, sizeof (unit_tick)); bzero (unit_n_insns, sizeof (unit_n_insns)); @@ -1202,7 +1200,6 @@ actual_hazard_this_instance (unit, instance, insn, clock, cost) int unit, instance, clock, cost; rtx insn; { - int i; int tick = unit_tick[instance]; if (tick - clock > cost) @@ -1278,7 +1275,6 @@ actual_hazard (unit, insn, clock, cost) { /* Find the instance of the function unit with the minimum hazard. */ int instance = unit; - int best = instance; int best_cost = actual_hazard_this_instance (unit, instance, insn, clock, cost); int this_cost; @@ -1293,7 +1289,6 @@ actual_hazard (unit, insn, clock, cost) clock, cost); if (this_cost < best_cost) { - best = instance; best_cost = this_cost; if (this_cost <= cost) break; @@ -1684,7 +1679,7 @@ sched_analyze_1 (x, insn) if (GET_CODE (dest) == REG) { - register int offset, bit, i; + register int i; regno = REGNO (dest); @@ -2142,7 +2137,6 @@ sched_analyze (head, tail) } else if (GET_CODE (insn) == CALL_INSN) { - rtx dest = 0; rtx x; register int i; @@ -2237,7 +2231,7 @@ sched_note_set (b, x, death) rtx x; int death; { - register int regno, j; + register int regno; register rtx reg = SET_DEST (x); int subreg_p = 0; @@ -2664,7 +2658,7 @@ static void create_reg_dead_note (reg, insn) rtx reg, insn; { - rtx link, backlink; + rtx link; /* The number of registers killed after scheduling must be the same as the number of registers killed before scheduling.
