There are use cases where the split debuginfo file of a given binary
is under a given root directory and that the split debuginfo file
itself depends on an alternate debuginfo file that is under another
unrelated root directory.
In that case, the dwarf reader must be able to look for the debuginfo
files under several unrelated root directories. The tools abidiff and
abidw must thus support having several occurences of the option
--debug-info-dir1 (or --debug-info-dir2) meaning that the debuginfo
files for the binary must be looked for under several root
directories.
This is what this patch does.
* doc/manuals/abidiff.rst: Adjust doc for the
--debug-info-dir{1,2} that can now be provided several times.
* include/abg-dwarf-reader.h ({create, reset}_read_context)
(read_corpus_from_elf): Take a vector of debug info root dirs.
* include/abg-tools-utils.h (trim_leading_string)
(find_file_under_dir, make_path_absolute_to_be_freed)
(convert_char_stars_to_char_star_stars): Declare new functions.
* src/abg-dwarf-reader.cc (find_alt_debug_info_link): Renamed
find_alt_debug_info_location into this.
(find_alt_debug_info_path): Define new static function.
(find_alt_debug_info): Take a vector of debug info root dirs. Use
the new find_alt_debug_info_path to look into the debug info root
dirs for the alt debug info.
(read_context::debug_info_root_paths_): Define new data member.
(read_context::read_context): Take a vector of debug info root
dirs and initialize the new read_context::debug_info_root_paths_.
(read_context::{initialize, create_default_dwfl}): Take a vector
of debug info root dirs and adjust.
(read_context::{add_debug_info_root_paths,
add_debug_info_root_path, find_alt_debug_info}): Define new member
functions.
(read_context::load_debug_info): Look into the debug info roots
for split debug info files.
(create_read_context, read_corpus_from_elf): Take a vector of
debug info root dirs and adjust.
(has_alt_debug_info): Adjust.
* src/abg-tools-utils.cc (trim_leading_string)
(make_path_absolute_to_be_freed, find_file_under_dir)
(convert_char_stars_to_char_star_stars): Define new functions.
(entry_of_file_with_name): Define new static function.
(build_corpus_group_from_kernel_dist_under): Adjust.
* tests/print-diff-tree.cc (main): Adjust.
* tests/test-diff-dwarf.cc (main): Adjust.
* tests/test-ir-walker.cc (main): Adjust.
* tests/test-read-dwarf.cc (main): Adjust.
* tools/abicompat.cc (main): Adjust.
* tools/abidiff.cc (options::di_root_paths{1,2}): Changed
di_root_path{1,2} into this, change their types into vectors of
allocated char*.
(options::prepared_di_root_paths{1,2}): Define new data members.
(options::~options): Define new destructor.
(parse_command_line): Adjust.
(prepare_di_root_paths): Define new static function.
(handle_error): Remove arguments input_file_name,
debug_info_dir{1,2}. Now just take an instance of options
instead. Adjust.
(main): Adjust.
* tools/abidw.cc (options::dir_root_paths): Renamed dir_root_path
into this and make it be a vector of allocated char*.
(options::prepared_di_root_paths): Define new data member.
(options::~options): Free the allocated char* in
options::dir_root_paths.
(parse_command_line): Support several --debug-info-dir.
(load_corpus_and_write_abixml): Adjust.
(prepare_di_root_paths): Define static function.
(main): Adjust.
* tools/abilint.cc (main): Adjust.
