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.
