PR 44576: miss rate computation improvement for prefetching loop arrays.
2010-07-02 Changpeng Fang <changpeng.fang@amd.com>
PR middle-end/44576
* tree-ssa-loop-prefetch.c (compute_miss_rate): Return 1000 (out
of 1000) for miss rate if the address diference is greater than or
equal to the cache line size (the two reference will never hit the
same cache line).
