Extend readelf and objdump so that they will display and follow multiple links to separate debug information files.
PR 23843
* dwarf.h (struct separate_info): New structure for containing
information on separate debug info files.
* dwarf.c (struct dwo_info): New structure for containing dwo
links.
(first_dwo_info): Chain of dwo_info structures.
(first_separate_file): Chain of separate_info structures.
(separate_debug_file, separate_debug_filename): Delete.
(fetch_alt_indirect_string): Scan all separate debug info files
for the requested string.
(add_dwo_info): New function.
(add_dwo_name): New function.
(add_dwo_dir): New function.
(add_dwo_id: New function.
(free_dwo_info): New function.
(read_and_display_attr_value): Store DWO data using the new
functions.
(load_debug_section_with_follow): If necessary, scan the list of
separate debug info files for the requested section.
(add_separate_debug_file): New function.
(load_separate_debug_info): Call add_separate_debug_file to store
the information on the newly loaded file.
(load_dwo_file): Likewise.
(load_separate_debif_file): Rename to load_separate_debug_files.
Change return type to boolean. If following links then attempt to
load all separate debug info files, not just the first one.
(free_debug_memory): Release memory in dwo_info and separate_info
chains.
* objdump.c (dump_dwarf): Iterate over all loaded debg info files.
* readelf.c (process_object): Likewise.
* doc/debug.options.texi: Update descriptions of links and
follow-links options.
* testsuite/binutils-all/objdump.WK2: Update expected output.
* testsuite/binutils-all/readelf.k2: Likewise.
* NEWS: Announce the new feature.
