[4.9] Additional SLM tuning. Backport from trunk.
2014-11-24 Richard Biener <rguenther@suse.de> PR tree-optimization/55334 * function.h (struct function): Add last_clique member. * tree-inline.c (remap_dependence_clique): New function. (remap_gimple_op_r): Remap dependence cliques in MEM_REFs. (copy_tree_body_r): Likewise. (copy_cfg_body): Free dependence map. (copy_gimple_seq_and_replace_locals): Likewise. * tree-pretty-print.c (dump_generic_node): Dump dependence info. * tree-ssa-alias.c (refs_may_alias_p_1): Use dependence info to answer alias query. * tree-ssa-structalias.c: Include tree-phinodes.h, ssa-iterators.h, tree-pretty-print.h and gimple-walk.h. (struct variable_info): Add is_restrict_var flag and ruid member. (new_var_info): Initialize is_restrict_var. (make_constraint_from_restrict): Likewise. (create_variable_info_for): Exclude restricts from global vars from new handling. (intra_create_variable_infos): But not those from parameters. (visit_loadstore): New function. (maybe_set_dependence_info): Likewise. (compute_dependence_clique): Likewise. (compute_may_aliases): Call compute_dependence_clique. * tree-data-ref.c (dr_analyze_indices): Copy dependence info to fake MEM_REF. (dr_may_alias_p): Use recorded dependence info to answer alias query. * tree-core.h (struct tree_base): Add clique, base struct in union. * tree.h (MR_DEPENDENCE_CLIQUE): New macro. (MR_DEPENDENCE_BASE): Likewise. * tree-inline.h (dependence_hasher): New hash-map kind. (struct copy_body_data): Add dependence_map pointer. * tree-streamer-in.c (unpack_value_fields): Stream dependence info. * tree-streamer-out.c (streamer_pack_tree_bitfields): Likewise. * gcc.dg/tree-ssa/restrict-5.c: New testcase.
