tree-ssa-loop-niter.c (idx_infer_loop_bounds): Add and use argument "reliable".
* tree-ssa-loop-niter.c (idx_infer_loop_bounds): Add and use argument "reliable". (infer_loop_bounds_from_ref, infer_loop_bounds_from_array): Add argument "reliable". Propagate it through calls. (infer_loop_bounds_from_undefined): Derive number of iterations estimates from references in blocks that do not dominate loop latch. (gcov_type_to_double_int): New function. (estimate_numbers_of_iterations_loop): Use gcov_type_to_double_int and expected_loop_iterations_unbounded. * cfgloopanal.c (expected_loop_iterations_unbounded): New function. (expected_loop_iterations): Use expected_loop_iterations_unbounded. * tree-data-ref.c (estimated_loop_iterations): Export. (get_references_in_stmt): Fix -- do not return addresses of local objects. * cfgloop.h (expected_loop_iterations_unbounded, estimated_loop_iterations): Declare. From-SVN: r123630
