Re: [patch] Merge data dependence bits for interchanging swim loops

[Sebastian Pop <sebastian dot pop at cri dot ensmp dot fr>]

Somebody, probably Daniel, has committed the Changelog part of my
patch that is still not reviewed, nor committed.  I've committed the
following fix.

-	* Makefile.in (tree-ssa-loop-niter.o): Depends on tree-data-ref.h.
-	* cfgloop.c (initialize_loops_parallel_p): New.
-	(flow_loops_find): Initialize the parallel_p field to true for all
-	the loops.
-	* tree-ssa-loop-niter.c: Include "tree-data-ref.h".
-	(estimate_numbers_of_iterations_loop): Infers the loop bounds from
-	the size of the data accessed in the loop.
-	(struct nb_iter_bound): Moved...
-	* cfgloop.h (struct nb_iter_bound): ... here.
-	(estimated_nb_iterations, parallel_p): New fields in struct loop.
-	(record_estimate): Declare extern here.
-	* tree-chrec.c: Fix comments.
-	(nb_vars_in_chrec): New function.
-	* tree-chrec.h (nb_vars_in_chrec): Declared here.
-	* tree-data-ref.c: Don't include lambda.h, that is already included
-	in tree-data-ref.h.
-	(tree_fold_divides_p): Don't check for integer_onep.
-	(tree_fold_bezout): Removed.
-	(gcd): New static duplicated function.
-	(int_divides_p, dump_subscript): New.
-	(dump_data_dependence_relation): Use dump_subscript.
-	(dump_dist_dir_vectors, dump_ddrs, compute_estimated_nb_iterations,
-	estimate_niter_from_size_of_data): New.
-	(analyze_array_indexes, analyze_array): Call
-	estimate_niter_from_size_of_data during	the detection of array
-	references.  Pass in a pointer to the statement that contains the
-	array reference.
-	(all_chrecs_equal_p): New.
-	(compute_distance_vector): Renamed compute_subscript_distance.
-	Deal with multivariate conflict functions.
-	(initialize_data_dependence_relation): Initialize DDR_AFFINE_P,
-	DDR_SIZE_VECT, DDR_DIST_VECT, and DDR_DIR_VECT.

-	compute_overlap_steps_for_affine_1_2): New.
-	(analyze_siv_subscript_affine_cst): Removed.
-	(analyze_subscript_affine_affine): Disprove dependences based on the
-	iteration domains.  Solve the univariate dependence case as before,
-	but use lambda_matrix_right_hermite instead of tree_fold_bezout.
-	Implement the multivariate case of 2 versus 1 variables.
-	(undetermined_conflicts_p, no_conflicts_p): New.
-	(build_classic_dist_vector, build_classic_dir_vector): Implement some
-	unhandled cases.

 	the predicate cannot be computed, don't initialize the result to
 	false.
