	gcc            : ChangeLog tree-data-ref.c tree-ssa-loop-niter.c 
	                 tree-vrp.c 

Log message:
	* tree-data-ref.c (compute_estimated_nb_iterations,
	analyze_array_indexes, compute_overlap_steps_for_affine_1_2,
	analyze_subscript_affine_affine, find_data_references_in_loop):
	Fixed to use chrec_contains_undetermined to test the values of
	loop->estimated_nb_iterations.
	* tree-ssa-loop-niter.c (estimate_numbers_of_iterations_loop):
	Compute the estimation only when loop->estimated_nb_iterations
	has not yet been initialized.
	(convert_step_widening, scev_probably_wraps_p): Add a call to
	estimate_numbers_of_iterations_loop.
	* tree-vrp.c (execute_vrp): Don't call estimate_numbers_of_iterations.
