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.

This is the Application Binary Interface Generic Analysis and Instrumentation Library. It aims at constructing, manipulating, serializing and de-serializing ABI-relevant artifacts. The set of artifacts that we are intersted is made of quantities like types, variable, fonctions and declarations of a given library or program. For a given library or program this set of quantities is called an ABI corpus. This library aims at (among other things) providing a way to comparing two ABI Corpuses, provide detailed information about their differences, and help build tools to infer interesting conclusions about these differences. You are welcome to contribute to this project after reading the files CONTRIBUTING and COMMIT-LOG-GUIDELINES files in the source tree. Communicating with the maintainers of this project -- including sending patches to be include to the source code -- happens via email at libabigail@sourceware.org.
