Support symbol lookups from ELF * include/abg-dwarf-reader.h (symbol_type, symbol_binding): New enums. (operator<<): Declare new overloads for the new enums above. (lookup_symbol_from_elf, lookup_public_function_symbol_from_elf): Declare new entry points. * src/abg-dwarf-reader.cc (lookup_symbol_from_elf) (lookup_public_function_symbol_from_elf) (lookup_public_variable_symbol_from_elf): Define new static functions. (read_context::elf_{module_, handle}_): New data members. (read_context::{elf_module, elf_handle}): New accessors. (read_context::load_debug_info): Store the elf module into read_context::_elf_module_. Adjust. (read_context::{lookup_symbol_from_elf, lookup_public_function_symbol_from_elf, lookup_public_variable_symbol_from_elf}): New member functions. (lookup_symbol_from_elf, lookup_public_function_symbol_from_elf) (operator<<): Define public entry points. * tools/bisym.cc: New tool to lookup a symbol in an elf file. * tools/Makefile.am: Add the bisym.cc source file to the distribution and arrange to compile it into a 'bisym' executable. * tests/test-lookup-syms.cc: New test harness. * tests/data/test-lookup-syms/test0-report.txt: New test input for the harness above. * tests/data/test-lookup-syms/test0.cc: Likewise. * tests/data/test-lookup-syms/test0.o: Likewise * tests/data/test-lookup-syms/test01-report.txt: Likewise. * tests/data/test-lookup-syms/test02-report.txt: Likewise. * tests/Makefile.am: Build the new runtestlookupsyms test and add the new files to the distribution.

Support alternate debug info sections ABGBZ#17193 * include/abg-dwarf-reader.h (class read_context) (typedef read_context_sptr, create_read_context) (has_alt_debug_info): Declare these. (read_corpus_from_elf): Declare new overload. * src/abg-dwarf-reader.cc (find_alt_debug_info) (is_die_attribute_resolved_through_gnu_ref_alt) (build_primary_die_parent_relations_under) (build_alternate_die_parent_relations_under): Define new static functions. (read_context::{alt_dwarf_, alt_debug_info_path_, alternate_die_decl_map_, alternate_die_parent_map_}): New data members. (read_context::{alt_dwarf, alt_debug_info_path, alternate_die_decl_map, associate_die_to_decl_primary, associate_die_to_decl_alternate, associate_die_to_decl, lookup_decl_from_die_offset_primary, lookup_decl_from_die_offset_alternate, lookup_decl_from_die_offset, alternate_die_parent_map}): New member functions. (read_context::load_debug_info): Painfully Get a handle on the alternate debug info section too. We shouldn't have to do all this work; we could use the new dwarf_getalt() function from libdw, but we cannot as we want to support supports that predate that api. When a version of elfutils gets released with that api though, we should conditionally use that instead. (build_ir_node_from_die, get_parent_die, get_scope_for_die) (build_namespace_decl_and_add_to_ir) (build_class_type_and_add_to_ir, build_qualified_type) (build_pointer_type_def, build_reference_type, build_typedef_type) (build_var_decl, build_function_decl): Take a new parameter that tells if the input DIE is from alternate debug info. Adjust their code accordingly. (die_die_attribute): Take a new output parameter that tells if the resolved DIE is from alternate debug info. Also take a new parameter that tells if the input DIE is from alternate debug info sections. (build_die_parent_relations_under): Take the DIE -> parent map to act upon. Also, add a new overload that takes a flag saying if the DIE is from alternate debug info or not, and act upon that. (build_die_parent_maps): Renamed build_die_parent_map into this and make it build DIE -> parent DIE relationship for the alternate debug info file as well. (find_last_import_unit_point_before_die, ): Adjust to use the information about if the relevant DIEs are in alternate debug info or not. (build_translation_unit_and_add_to_ir): Clear the alternate DIE -> decl map, that is per TU just as the primary DIE -> decl map. Adjust to use the information about if the relevant DIEs are in alternate debug info or not. (read_debug_info_into_corpus): Build the two DIE -> DIE parent maps (one for the primary debug info and one for the alternate debug info). (create_read_context, has_alt_debug_info): Define new public entry points. (read_corpus_from_elf): New entry point overload that takes a read_context. * tools/bidw.cc (options::{check_alt_debug_info_path, show_base_name_alt_debug_info_path}): New data members. (display_usage): Update for the two new options --check-alternate-debug-info and check-alternate-debug-info-base-name. (parse_command_line): Parse the two options above. (main) Handle the two new options above. * tests/Makefile.am: Build the new runtestaltdwarf test. Add the new data/test-alt-dwarf-file/* files to the build system. * tests/test-alt-dwarf-file.cc: New test driver. * tests/data/test-alt-dwarf-file/test0-common.cc: New test input files. * tests/data/test-alt-dwarf-file/libtest0-common.so: Likewise. * tests/data/test-alt-dwarf-file/test0.cc: Likewise. * tests/data/test-alt-dwarf-file/libtest0.so: Likewise. * tests/data/test-alt-dwarf-file/test0.h: Likewise. * tests/data/test-alt-dwarf-file/test0-common-dwz.debug: Likewise. * tests/data/test-alt-dwarf-file/test0-debug-dir/.build-id/16/7088580c513b439c9ed95fe6a8b29496495f26.debug: Likewise. * tests/data/test-alt-dwarf-file/test0-debug-dir/test0-common-dwz.debug: Likewise. * tests/data/test-read-dwarf/test1.abi: Adjust. bidw doesn't emit an abstract constructor/destructor anymore. It emits just the functions matching the cdtor symbols found in the binary. * tests/data/test-read-dwarf/test2.so.abi: Likewise. Signed-off-by: Dodji Seketeli <dodji@redhat.com>
