Reduce the cost in miss rate computation.
2010-07-02 Changpeng Fang <changpeng.fang@amd.com>
* tree-ssa-loop-prefetch.c (compute_miss_rate): Rename to
is_miss_rate_acceptable. Pull total_positions computation
out of the loops. Early return if miss_positions exceeds
the acceptable threshold.
* tree-ssa-loop-prefetch.c (prune_ref_by_group_reuse): Call
is_miss_rate_acceptable after renaming of compute_miss_rate.
