* include/abg-dwarf-reader.h (set_read_context_corpus_group)
	(read_and_add_corpus_to_group_from_elf, set_ignore_symbol_table)
	(get_ignore_symbol_table): Declare new functions.
	* abg-dwarf-reader.cc (read_context::options_type): Define new
	type.
	(die_dependant_container_set::clear): Define new member function.
	(read_context::{bss, tesxt, rodata, data, data1}_section_): Add
	new data members.
	(read_context::{symbol_versionning_sections_loaded_,
	symbol_versionning_sections_found_}): Likewise.
	(read_context::corpus_group_): Likewise.
	(read_context::{load_in_linux_kernel_mode, load_all_types,
	show_stats, do_log_}): Replace these options by ..
	(read_context::options_): ... this instance of the new
	read_context:options_type.
	(read_context::read_context): Adjust.
	(read_context::{clear_alt_debug_info_data, clear_per_corpus_data,
	env, get_data_section_for_variable_address, load_all_types,
	load_in_linux_kernel_mode, show_stats, do_log}): Adjust.
	(create_read_context): Adjust.
	(read_context::~read_context): Define destructor.
	(read_context::{options, bss_section, text_section,
	rodata_section, data_section, data1_section, current_corpus_group,
	has_corpus_group, main_corpus_from_current_group,
	main_corpus_from_current_group,
	current_corpus_is_main_corpus_from_current_group,
	should_reuse_type_from_corpus_group}): Define new member
	functions.
	(read_context::get_die_qualified_type_name): Handle the name of
	the current translation unit.
	(read_context::load_symbol_maps): Really don't load (linux kernel
	specific) symbol maps if we were told to ignore the ELF symbol
	table.
	(set_ignore_symbol_table, get_ignore_symbol_table)
	(create_default_var_sym, create_default_fn_sym, add_symbol_to_map)
	(set_read_context_corpus_group)
	(read_and_add_corpus_to_group_from_elf): Define new functions.
	(build_type_decl, build_typedef_type, build_enum_type)
	(add_or_update_class_type)
	(add_or_update_union_type): Reuse the type being built, from the
	main corpus of the corpus group.
	(build_qualified_type): Cleanup logic.
	(build_var_decl, build_function_decl): Create a default symbol for
	the variable or function if we are supposed to ignore the symbol
	table of the current binary.  Add that symbol to the symbol table
	that is created in the read context.
	(read_debug_info_into_corpus): Don't load the ELF symbol table
	information if we are asked to ignore the symbol table.  But set
	the symbol table that we built artificially while loading
	functions and variables, into the ABI corpus being built.
	(read_context::maybe_adjust_var_sym_address): Adjust.
	(build_ir_node_from_die): Add ir node to its logical scope.  For
	the C language, the scope of a type is the global scope.
	(read_corpus_from_elf): Don't load ELF properties if we were asked
	to avoid the ELF symbol table.
	* include/abg-comparison.h (compute_diff): Declare ...
	* src/abg-comparison.cc (compute_diff): ... an overload to compare
	corpus_group.
	* tools/kmidiff.cc: New tool.

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 compare
two ABI Corpora (apparently the plural of corpus is copora, heh,
that's cool), 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.

sending patches to be include to the source code -- happens via email
