re PR tree-optimization/18792 (ICE with -O1 -ftree-loop-linear on small test case)
2005-01-06 Daniel Berlin <dberlin@dberlin.org>
Fix PR tree-optimization/18792
* tree-data-ref.c (build_classic_dist_vector): Change first_loop
to first_loop_depth, and use loop depth instead of loop number.
(build_classic_dir_vector): Ditto.
(compute_data_dependences_for_loop): Use depth, not loop number.
* tree-loop-linear.c (try_interchange_loops): Use loop depth, not loop
number. Pass in loops, instead of loop numbers.
(gather_interchange_stats): Ditto.
(linear_transform_loops): Ditto.
