PR tree-optimization/22236
* tree-cfg.c (print_pred_bbs, print_succ_bbs): Correctly print successors and predecessors. * tree-chrec.c (chrec_convert): Before converting, check that sequences don't wrap. * tree-data-ref.c (compute_estimated_nb_iterations): Moved ... (analyze_array): Extern. (find_data_references_in_loop): Remove call to compute_estimated_nb_iterations. * tree-data-ref.h (analyze_array): Declared. * tree-flow-inline.h (single_ssa_tree_operand, single_ssa_use_operand, single_ssa_def_operand, zero_ssa_operands): Fix documentation. * tree-flow.h (scev_probably_wraps_p): Declare with an extra parameter. * tree-scalar-evolution.c (instantiate_parameters_1): Factor entry condition. * tree-ssa-loop-ivcanon.c: Fix documentation. * tree-ssa-loop-ivopts.c (idx_find_step): Add a fixme note. * tree-ssa-loop-niter.c (compute_estimated_nb_iterations): ... here. (infer_loop_bounds_from_undefined): New. (estimate_numbers_of_iterations_loop): Use infer_loop_bounds_from_undefined. (used_in_pointer_arithmetic_p): New. (scev_probably_wraps_p): Pass an extra parameter. Call used_in_pointer_arithmetic_p. Check that AT_STMT is not null. (convert_step): Fix documentation. * tree-vrp.c (adjust_range_with_scev): Call instantiate_parameters. Use initial_condition_in_loop_num and evolution_part_in_loop_num instead of CHREC_LEFT and CHREC_RIGHT. Adjust the call to scev_probably_wraps_p. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@103055 138bc75d-0d04-0410-961f-82ee72b054a4
