* tree-chrec.c (chrec_fold_plus_poly_poly, chrec_fold_plus_1, chrec_fold_multiply): Use fold_convert or build_int_cst_type instead od fonvert. * tree-scalar-evolution.c (compute_overall_effect_of_inner_loop, add_to_evolution, set_nb_iterations_in_loop, follow_ssa_edge_in_rhs, follow_ssa_edge_in_rhs): Ditto. * tree-ssa-loop-ivopts.c (struct iv): Add base_object field. (dump_iv): Dump base_object. (dump_use, dump_cand): Use dump_iv. (determine_base_object): New function. (alloc_iv): Initialize base_object field. (record_use): Clear the ssa_name field of iv. (get_computation_cost_at): Do not use difference of addresses of two different objects. (may_eliminate_iv): Do not require the loop to have just single exit. * tree-ssa-loop-niter.c (zero_p): Do not check for overflows. (nonzero_p): New function. (inverse, number_of_iterations_cond, simplify_using_outer_evolutions, tree_simplify_using_condition, simplify_using_initial_conditions, loop_niter_by_eval, find_loop_niter_by_eval, estimate_numbers_of_iterations_loop, compare_trees, upper_bound_in_type, lower_bound_in_type, can_count_iv_in_wider_type_bound): Use buildN instead of build. Use fold_convert or build_int_cst_type instead of convert. Use (non)zero_p instead of integer_(non)zerop. From-SVN: r88388
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*.
