tree-ssa-loop-prefetch.c (mem_ref_group, ar_data): Change step to tree.
2010-05-19 Christian Borntraeger <borntraeger@de.ibm.com>
* tree-ssa-loop-prefetch.c (mem_ref_group, ar_data): Change step
to tree.
(dump_mem_ref): Adopt debug code to handle a tree as step. This
also checks for a constant int vs. non-constant but
loop-invariant steps.
(find_or_create_group): Change the sort algorithm to only consider
steps that are constant ints.
(idx_analyze_ref): Adopt code to handle a tree instead of a
HOST_WIDE_INT for step.
(gather_memory_references_ref): Handle tree instead of int and be
prepared to see a NULL_TREE.
(prune_ref_by_self_reuse, prune_ref_by_group_reuse): Do not prune
prefetches if the step cannot be calculated at compile time.
(issue_prefetch_ref): Issue prefetches for non-constant but
loop-invariant steps.
