	(L1_CACHE_SIZE_BYTES, L2_CACHE_SIZE_BYTES, NONTEMPORAL_FRACTION):
	New macros.
	(struct mem_ref): Add field reuse_distance.
	(find_or_create_group, record_ref): Use XNEW instead of xcalloc.
	Initialize reuse_distance field.
	(issue_prefetch_ref): Select temporality of prefetch according to
	reuse_distance.
	(volume_of_references, volume_of_dist_vector, add_subscript_strides,
	self_reuse_distance, determine_loop_nest_reuse): New functions.
	(loop_prefetch_arrays): Call determine_loop_nest_reuse.
	(tree_ssa_prefetch_arrays): Dump L2 cache size.
	* Makefile.in (tree-ssa-loop-prefetch.o): Add TREE_DATA_REF_H
