So perhaps:

+++ gcc/haifa-sched.c 2014-02-19 07:58:38.191381581 +0100
@@ -2550,7 +2550,7 @@ rank_for_schedule (const void *x, const
return INSN_LUID (tmp) - INSN_LUID (tmp2);
}
- if (live_range_shrinkage_p)
+ if (live_range_shrinkage_p && sched_pressure != SCHED_PRESSURE_NONE)
{
/* Don't use SCHED_PRESSURE_MODEL -- it results in much worse
code. */
BTW, why
if (sched_pressure != SCHED_PRESSURE_NONE)
free_global_sched_pressure_data ();
when free_global_sched_pressure_data () contains the same guard and thus could
be called unconditionally?
