*	In gcc/ada/	dberlin	2005-03-13	1	-0/+45
	2005-03-12 Daniel Berlin <dberlin@dberlin.org> * misc.c (gnat_post_options): Turn off structural aliasing for now. In gcc/ 2005-03-12 Daniel Berlin <dberlin@dberlin.org> * tree-flow-inline.h (ref_contains_array_ref): New function. (lookup_subvars_for_var): Ditto. (get_subvars_for_var): Ditto. (var_can_have_subvars): Ditto. * tree-flow.h (mem_tag_kind): Add STRUCT_FIELD. (struct subvar): New type. * tree-dfa.c (okay_component_ref_for_subvars): New function. * tree-optimize.c (init_tree_optimization_passes): Call pass_create_structure_vars. * tree-ssa-alias.c: Include vec.h. (init_alias_info): Don't auto-clear call clobbered on struct-field tags. (compute_flow_insensitive_aliasing): Handle subvars. (group_aliases): Handle STRUCT_FIELD aliases. (setup_pointers_and_addressables): Ditto. Don't mark variables non-addressable if they still have addressable subvars. Also mark subvars addressable when the real variable is marked addressable. (add_pointed_to_var): Try to prune the pointed-to set by only pointing to subvars when possible. Otherwise, make sure we set addresses_needed and pt_vars to properly include subvars. (bitpos_of_field): New function. (push_fields_onto_fieldstack): Ditto. (get_or_create_used_part_for): Ditto. (create_overlap_variables_for): Ditto. (find_used_portions): Ditto. (create_structure_vars): Ditto. (pass_create_structure_vars): New structure. * tree-ssa-operands.c (finalize_ssa_v_must_defs): Remove assert. (get_expr_operands): Handle subvars. Also try to turn COMPONENT_REF accesses into must-defs now that we can accurately portray it. (note_addressable): Try to only mark as addressable those subvars we know a COMPONENT_REF touches. (overlap_subvar): New function. * tree-vect-analyze.c (vect_object_analysis): Add new parameter. Handle subvar storing. (vect_address_analysis): Update caller of vect_object_analysis. * tree-vect-transform.c (vect_create_data_ref_ptr): Copy subvars. * tree-vectorizer.h (struct _stmt_vec_info): Add subvars member. (STMT_VINFO_SUBVARS): New macro. * common.opts: add flag_tree_salias. * opts.c (decode_options): flag_tree_salias defaults to on. * doc/invoke.texi: Document fdump-tree-svars and -ftree-salias. * doc/tree-ssa.texi: Document structural alias analysis. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@96362 138bc75d-0d04-0410-961f-82ee72b054a4
