* 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.
