We have the kmidiff program that takes two Linux Kernel trees containing the vmlinux binary and its modules and compare their Kernel Module Interface, aka KMI. We need to be able to serialize (save in a file) a representation of that KMI. We need to load that KMI back, and compare two serialized KMIs. This patch implements the serialization of the KMI of a Linux Kernel tree. It actually serializes an instance of abigail::ir::corpus_group that is a collection of instances of abigail::ir::corpus. The KMI of each individual binary (vmlinux or kernel module) is represented by one abigail::ir::corpus. All the corpora share the same definitions of types and decls, whenever that makes sense. The patch thus factorizes the routines used to walk a Linux kernel out of the kmidiff program. These routines are then re-used in the abidw program to make it walk a Linux kernel tree (when the --linux-tree option is provided), load the vmlinux and module binaries as an instance of abigail::corpus_group and serialize it out into an output stream. * include/abg-tools-utils.h (check_dir) (get_binary_paths_from_kernel_dist) (build_corpus_group_from_kernel_dist_under): Declare new functions. The last two functions are being moved from tools/kmidiff.cc so that they can be re-used. * include/abg-writer.h (write_corpus): Declare one overload that takes a write_context parameter. (write_corpus_group): Declare three overloads of this new function. * src/abg-tools-utils.cc (check_dir): Define new function. (load_generate_apply_suppressions, is_vmlinux, is_kernel_module) (find_vmlinux_and_module_paths) (get_binary_paths_from_kernel_dist) (build_corpus_group_from_kernel_dist_under): Define new functions. * src/abg-writer.cc (write_context::set_annotate): Define new member function. (write_corpus): Add an overload that takes a write_context. Adapt the existing overload to make it use this new one. (write_corpus_group): Define this new function and two additional overloads for it. * tools/kmidiff.cc (set_suppressions, is_vmlinux) (is_kernel_module, find_vmlinux_and_module_paths) (get_binary_paths_from_kernel_dist) (build_corpus_group_from_kernel_dist_under): Remove. (main): Adjust the call to build_corpus_group_from_kernel_dist_under as its arguments are now adapted since it's been factorized out into abg-tools-utils.h. * tools/abidw.cc (options::corpus_group_for_linux): Define new data member. (options::options): Adjust. (display_usage): Add help strings for the new --linux-tree option. (load_corpus_and_write_abixml): Factorize this function out of the main function. (load_kernel_corpus_group_and_write_abixml): Define new function. (main): Use the factorized load_corpus_and_write_abixml and the new load_corpus_and_write_abixml functions. * tests/test-read-write.cc: Adjust. * doc/manuals/abidw.rst: Add documentation for the new --linux-tree option.
