DWARF-5 basic functionality
this is a kitchen-sink patch for everything that did not fit into its own patch. DWO is not yet implemented. gdb/ChangeLog 2017-02-20 Jan Kratochvil <jan.kratochvil@redhat.com> * defs.h (read_unsigned_leb128): New declaration. * dwarf2loc.c (decode_debug_loclists_addresses): New function. (decode_debug_loc_dwo_addresses): Update DEBUG_LOC_* to DW_LLE_*. (dwarf2_find_location_expression): Call also decode_debug_loclists_addresses. Handle DWARF-5 ULEB128 length. * dwarf2loc.h (dwarf2_version): New declaration. * dwarf2read.c (struct dwarf2_per_objfile): Add loclists, line_str, rnglists. (dwarf2_elf_names): Add .debug_loclists, .debug_line_str, .debug_rnglists. (struct dwop_section_names): Add loclists_dwo. (dwop_section_names): Add .debug_loclists.dwo. (struct comp_unit_head): Add unit_type, signature, type_offset_in_tu. (struct dwarf2_per_cu_data): Add dwarf_version. (struct dwo_sections): Add loclists. (struct attr_abbrev): Add implicit_const. (read_indirect_line_string): New declaration. (read_unsigned_leb128): Delete declaration. (rcuh_kind): New definition. (read_and_check_comp_unit_head): Change parameter is_debug_types_section to section_kind. (dwarf2_locate_sections): Handle loclists, line_str and rnglists. (read_comp_unit_head): Change parameter abfd to section, add parameter section_kind. Handle DWARF-5. (error_check_comp_unit_head): Accept also DWARF version 5. (read_and_check_comp_unit_head): Change parameter is_debug_types_section to section_kind. (read_and_check_type_unit_head): Delete function. (read_abbrev_offset): Handle DWARF-5. (create_debug_type_hash_table): Add parameter section_kind. Process only DW_UT_type. Use signature and type_offset_in_tu from struct comp_unit_head. (create_debug_types_hash_table): Update create_debug_type_hash_table caller. (create_all_type_units): Call create_debug_type_hash_table. (read_cutu_die_from_dwo, init_cutu_and_read_dies): Change read_and_check_type_unit_head caller to read_and_check_comp_unit_head caller. (skip_one_die): Handle DW_FORM_implicit_const. (dwarf2_rnglists_process): New function. (dwarf2_ranges_process): Call dwarf2_rnglists_process for DWARF-5. (abbrev_table_read_table): Handle DW_FORM_implicit_const. (read_attribute_value): Handle DW_FORM_implicit_const, DW_FORM_line_strp. (read_attribute): Handle DW_FORM_implicit_const. (read_indirect_string_at_offset_from): New function from read_indirect_string_at_offset. (read_indirect_string_at_offset): Call read_indirect_string_at_offset_from. (read_indirect_line_string_at_offset): New function. (read_indirect_string): New function comment. (read_indirect_line_string): New function. (read_unsigned_leb128): Make it global. (dwarf2_string_attr): Handle DWARF-5. (add_include_dir_stub, read_formatted_entries): New functions. (dwarf_decode_line_header, dump_die_shallow, cu_debug_loc_section): Handle DWARF-5. (per_cu_header_read_in): Update read_comp_unit_head caller. (dwarf2_version): New function. * symfile.h (struct dwarf2_debug_sections): Add loclists, line_str and rnglists. * xcoffread.c (dwarf2_xcoff_names): Update struct dwarf2_debug_sections fields. gdb/testsuite/ChangeLog 2017-02-20 Jan Kratochvil <jan.kratochvil@redhat.com> * gdb.dwarf2/dw2-error.exp (file $testfile): Update expected string.
