	gcc            : Makefile.in ChangeLog.lno cfgloop.h 
	                 tree-data-ref.c tree-data-ref.h 
	                 tree-ssa-loop-niter.c tree-loop-linear.c 

Log message:
	* Makefile.in (tree-ssa-loop-niter.o): Depends on TREE_DATA_REF_H.
	* cfgloop.h (struct nb_iter_bound): Moved here.
	(record_estimate_niter): Declared extern here.
	* tree-data-ref.c (compute_estimated_nb_iterations): New.
	(estimate_niter_from_size_of_data): Pass in the statement containing
	the data reference.  Record the estimations in loop instead of
	computing the minimum of the loop bounds.  Check for null pointers
	before computing the estimation.
	(analyze_array_indexes): Pass in the statement containing the data
	reference.
	(analyze_array): Pass to analyze_array_indexes the statement.
	(find_data_references_in_loop): Now extern.  Compute and initialize
	the estimated_nb_iterations.
	* tree-data-ref.h (find_data_references_in_loop): Declared here.
	* tree-ssa-loop-niter.c: Include tree-data-ref.h.
	(struct nb_iter_bound): Moved to cfgloop.h.
	(record_estimate): Renamed record_estimate_niter.
	(estimate_numbers_of_iterations_loop): Add a call to the data
	reference analyzer that finds the bounds based on the data size.
	
	* tree-loop-linear.c (gather_interchange_stats): Don't compute the
	inner loop, but instead, compute it.  Pass in the offset of
	the loop nest.
	(try_interchange_loops): Pass to gather_interchange_stats the offset
	of the loop nest.
	(linear_transform_loops): Don't fail to transform a loop nest if the
	loop nest itself has a sibling loop.
