History
Dodji Seketeli 929db0a880 Detect and report changes in ELF architecture 
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.
