2012-08-09 Martin Jambor <mjambor@suse.cz> * cgraph.h (cgraph_indirect_call_info): Field anc_offse renamd to offset, updated all users. New field agg_contents. * ipa-prop.h (jump_func_type): Removed IPA_JF_CONST_MEMBER_PTR. (ipa_pass_through_data): New field agg_preserved. (ipa_ancestor_jf_data): Likewise. (ipa_member_ptr_cst): Removed. (ipa_agg_jf_item): New type. (ipa_agg_jump_function): Likewise. (ipa_jump_func): New field agg. Removed field member_cst. (ipa_get_jf_pass_through_agg_preserved): New function. (ipa_get_jf_ancestor_agg_preserved): Likewise. (ipa_get_jf_member_ptr_pfn): Removed. (ipa_find_agg_cst_for_param): Declare. (ipa_load_from_parm_agg): Likewise. * ipa-prop.c (param_analysis_info): Fields modified and visited_statements rename to parm_modified and parm_visited_statements respectively, added fields ref_modified, ref_visited_statements, pt_modified and pt_visited_statements. (ipa_print_node_jump_functions_for_edge): Do not dump const member functions. Dump agg_preserved flags and aggregate jump functions. (ipa_set_jf_simple_pass_through): Set also agg_preserved. (ipa_set_ancestor_jf): Likewise. (ipa_set_jf_arith_pass_through): Clear agg_preserved. (ipa_set_jf_member_ptr_cst): Removed. (is_parm_modified_before_stmt): Logic reversed, renamed to parm_preserved_before_stmt_p. Cache visited bitmap only for naked DECL parameters. All callers updated. (load_from_unmodified_param): Allow NULL parms_ainfo. (parm_ref_data_preserved_p): New function. (parm_ref_data_pass_through_p): Likewise. (ipa_load_from_parm_agg_1): Likewise. (ipa_load_from_parm_agg): Likewise. (compute_complex_assign_jump_func): Check if aggregate contents are preserved. (compute_complex_ancestor_jump_func): Likewise. (compute_scalar_jump_functions): Removed. (type_like_member_ptr_p): Also check field position are known and sane. (compute_pass_through_member_ptrs): Removed. (determine_cst_member_ptr): Likewise. (ipa_known_agg_contents_list): New type. (determine_known_aggregate_parts): New function. (compute_cst_member_ptr_arguments): Removed. (ipa_compute_jump_functions_for_edge): Compute all kinds of jump functions (scalar, aggregate and member pointer). (ipa_get_member_ptr_load_param): Incorporate into ipa_get_stmt_member_ptr_load_param, also pass back an offset. (ipa_note_param_call): Clear agg_contents. (ipa_analyze_indirect_call_uses): Also look for simple pointers loaded from aggregates. In such cases, store offset of the called field. (ipa_analyze_node): Initialize new fields of param_analysis_info. (update_jump_functions_after_inlining): Handle aggregate contents. (ipa_find_agg_cst_for_param): New function. (try_make_edge_direct_simple_call): Handle called aggregate values. (update_indirect_edges_after_inlining): Make sure aggregate preserving jump functions comply with type compatibility requirements. (ipa_edge_duplication_hook): Copy also aggregate jump functions. (ipa_write_jump_function): Stream agg_preserved flags and aggregate jump functions. Do not stream member pointer constant jump functions. (ipa_read_jump_function): Likewise. (ipa_write_indirect_edge_info): Stream new cgraph_indirect_call_info fields. (ipa_read_indirect_edge_info): Likewise. * testsuite/gcc.dg/ipa/iinline-4.c: New test. * testsuite/gcc.dg/ipa/iinline-5.c: Likewise. * testsuite/gcc.dg/ipa/iinline-6.c: Likewise. * testsuite/gcc.dg/ipa/iinline-7.c: Likewise. * testsuite/gcc.dg/lto/20120723_0.c: Likewise. * testsuite/gcc.dg/lto/20120723_1.c: Likewise.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with 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*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
