Libabigail does not take in account the architecture of the ELF file it reads. This patch changes that to represent the ELF architecture as a string, detect when that architecture changes accross two corpora being compared and emit a report about that change. * configure.ac: Detect the presence of libebl.a and add it to the list of library we depend on to build libabigail. Report when libelf.so is not found. * include/abg-comparison.h: (diff_context::show_architecture_change): Declare new accessors. (corpus_diff::architecture_changed): Declare new method. * include/abg-corpus.h (corpus::{get,set}_architecture_name): Declare new accessors. * src/abg-comparison.cc (diff_context::priv::show_architecture_change_): New data member. (diff_context::priv::priv): Initialize it. (diff_context::show_architecture_change): Define new accessors. (function_decl_diff::report): Report when the size/alignment of the function address changes. (corpus_diff::priv::architectures_equal_): New data member. (corpus_diff::priv::priv): Initialize it. (corpus_diff::priv::emit_diff_stats): Take in account changes of architecture. (corpus_diff::architecture_changed): Define new method. (corpus_diff::length): Take in account changes of architecture. (corpus_diff::report): Report about changes of architecture. (compute_diff): In the overload for corpus_diff_sptr, detect changes fo architecture. * src/abg-corpus.cc (corpus_priv::architecture_name): Define new data member. (corpus::{get,set}_architecture_name): Define new method. * src/abg-dwarf-reader.cc: Include elfutils/libebl.h to use ebl_openbackend() and ebl_backend_name() (read_context::elf_architecture_): Define new data member. (read_context::elf_architecture): Define new accessor. (read_context::{load_elf_architecture, load_remaining_elf_data}): Define new methods. (read_corpus_from_elf): Use ctxt.load_remaining_elf_data() in lieu of ctxt.load_dt_soname_and_needed. Stick the architecture into the corpus. * src/abg-reader.cc (read_corpus_from_input): Read the 'architecture' XML property. * src/abg-writer.cc (write_corpus_to_native_xml): Write the 'architecture' XML property. * tests/data/test-diff-dwarf/libtest-23-diff-arch-v0-32.so: New test input file. * tests/data/test-diff-dwarf/libtest-23-diff-arch-v0-64.so: Likewise. * tests/data/test-diff-dwarf/test-23-diff-arch-report-0.txt: Likewise. * tests/data/test-diff-dwarf/test-23-diff-arch-v0.cc: Source code for the binary test input files above. * tests/data/Makefile.am: Add the new test input files to the source distribution. * tests/test-diff-dwarf.cc (in_out_specs): Add the new test input data to the set of input data to run this test harness over. * tests/test-read-dwarf.cc (main): Do not take the architecture in account during comparisons.
