Make Front Ends first class citizens
This patch is a reorganization of the code to better support the need for having several different front-ends. In the libabigail pipeline of operation, a front-end is the part of the pipeline that analyses the input file. For instance, to analyse an ELF file, there is going to be one front-end. To analyse an ABIXML file, there is going to be another front-end. The middle-end is the part of the pipeline that interacts with the internal representation of ABIs. The middle-end knows how to analyse, compare ABI corpora provide an internal representation of the comparison result and analyse it as well. The back-end would be the part of the front-end that knows how to serialize internal representations of ABIs and ABI comparison results. One could thus imagine a front-end that understands the DWARF debug info format embedded in an ELF file. Another front-end would be dedicated to the CTF debug info format, and so on. Front-ends can share capabilities. For instance, DWARF and CTF front-ends are ELF based front end. As such, they share capabilities to understand the ELF format. They don't share much with the ABIXML front-end, however, as it's based on XML, which has almost nothing in common with ELF. To support this organization of concepts, this patch introduces a new hierarchy of types in the form of C++ classes. All front-ends implements the "Front End Interface". As such, they all inherit the abigail::fe_iface class. That class provides properties and behaviours that are shared by all front-ends that libabigail supports today. Namely, that class provides access to some of the options that are relevant to operating the front-end, to the ABI corpus or corpus group being constructed and to the suppression specifications that are considered. It also provides an abstract interface to perform the actual loading of the ABI corpus. That abstract interface has to be implemented by every single concrete front-end that is provided in libabigail. Then, there is the "ELF Reader" front-end. Its class name is abigail:🧝:reader. It inherits the abigail::fe_iface class and implements the fe_iface::load_corpus() so that the ELF properties of the ELF file be loaded and exposed in the ABI corpus as returned by the fe_iface::corpus() accessor. This ELF reader front-end also provides lots of capabilities that are specific to accessing ELF content. Then, there is a common base class for ELF-based front-ends to come, named abigail::elf_based_reader, which inherits the abigail:🧝:reader class. The purpose of this base class is to provide common properties and behaviours that are necessary to implement things like a DWARF or a CTF front-end, or any other front-end to support an ELF-based debug info format. Then, there is a CTF front-end which class is named abigail::ctf::reader. It inherits the abigail::elf_based_reader class and implements the fe_iface::load_corpus() interface to load and analyse the CTF-specific properties of the ELF file. To do this, abigail::ctf::reader::load_corpus() re-uses the abigail:🧝:load_corpus() member function to load the generic ELF parts of the ABI corpus. This reader then constructs the internal representation of the ABI corpus and passes it to the middle-end for further analysis. Then, there is a DWARF front-end which class is named abigail::dwarf::reader. It inherits the abigail::elf_based_reader class and implements the fe_iface::load_corpus() interface to load and analyse the DWARF-specific properties of the ELF file. To do this, abigail::dwarf::reader re-uses the abigail:🧝:load_corpus() member function to load the generic ELF parts of the ABI corpus, just like what the CTF front-end does. And then, just like the CTF front-end, this reader then constructs the internal representation of the ABI corpus and passes it to the middle-end for further analysis. Lastly, there is an ABIXML front-end which class is named abigail::abixml::reader. It inherits the abigail::fe_iface class directly. Note that unlike the two previous front-ends, this one doesn't inherit the elf_based_reader base class, for reasons that should be obvious to the astute reader by now. So, this front-end implements the abigail::fe_iface::load_corpus() abstract interface to load the properties for the ABI corpus represented in the ABIXML format, construct the internal representation and pass it to the middle-end for further analysis. The code of the tools got adapted to use these front-ends. The support of CTF is still guarded by #ifdef WITH_CTF pre-processor macros, but the one cool side effect is that the amount of guarded code is reduced. Basically, it's only the creation of the CTF front-end that is guarded. After its creation, what is returned is an instance of abigail::elf_based_reader::reader, exactly like what is returned by the creation of a DWARF front-end. Thus, the rest of the code is exactly the same, regardless of the kind of front-end. I believe this results in a more elegant and maintainable code. As a proof-of-concept, this patch also provides the create_best_elf_based_reader function. This function analyses the ELF file and depending on the kind of debug info it provides, returns the right front-end for it. Maybe at some point, all the #ifdef WITH_CTF guard pre-processing macros will be constrained in a single function like this one that will take the decision of instantiating the right front-end. The rest of the code will be as generic as it gets. The patch adjusts the reference abixml files produced by the CTF front-end because it now emits the <elf-needed> XML element which was not emitted before. This is done because the CTF front-end inherits the elf-reader which reads the "elf-needed" property from the binary, without explicit intervention from the CTF front-end. The patch passes 'make distcheck' on all the supported platforms. * include/abg-fwd.h (build_internal_underlying_enum_type_name): Move this here from src/abg-dwarf-reader.cc. * include/abg-elf-reader-common.h: Delete this file.

Use environment by reference.
This patch simplifies how the environment is created and passed around
the functions that create front ends. With this change, the
environment can simply be allocated on the stack and passed by
reference to the libabigail pipeline.
At the core of this change, type_or_decl_base::priv now carries a
const reference to an environment rather than a pointer. The side
effect is that type_or_decl_base can no longer be copied. This is not
a problem because throughout the years I could see that the use case
to copy ABI artifacts is just not there. Similarly, elf_symbol::priv
carries a const reference to environment now, no more a pointer.
Getters, setters and code that use the environment from the ABI
artifacts are updated accordingly.
The DWARF front-end can now be created by code that looks like this,
for instance:
vector<char**> debug_info_paths;
abigail::ir::environment env;
abigail::ctf_reader::read_context_sptr reader =
abigail::dwarf_reader::create_read_context("elf/file/to/analyze",
debug_info_paths, env);
elf_reader::status reading_status;
corpus_sptr abi_corpus =
abigail::dwarf_reader::read_corpus_from_elf(reader, reading_status);
/* then do something with the resulting abi_corpus*/
Note how, you don't need to use the "new" operator to instantiate the
"env" object of type environment. It can sit on the stack and it's
passed to the read_corpus_from_elf function by reference.
In other words, the internal representation types have been changed to
refer to the environment by reference, rather than requiring a pointer
to it.

Move dwarf_reader::status facilities to an abigail::elf_reader namespace
The DWARF reader is no longer the only ELF-based reader in libabigail: the CTF reader also operates on ELF files. Other ELF-based formats (such as BTF) may also join in the future. These readers share a lot of similarities: they all operate on object files, they fetch debugging information from certain sections, they rely on the symtab of the read object, the debugging info may be in a separated file (for certain formats) and so on. It follows that a lot of logic can be shared among all the ELF-based readers. This patch is oriented to that direction. A new namespace, abigail::elf_reader, is introduced with the goal of holding features and definitions useful for any ELF-based abigail reader. Then all the definitions related to the status resulting from extracting a corpus from an object file (the dwarf_reader::status) are moved to abigail::elf_reader. The utilities and tests are adjusted accordingly. Signed-off-by: Jose E.

Re-license the project to Apache v2 With LLVM Exception
Thanks to the previous work done, changing the license is just a matter of changing the SPDX identifer from "LGPL-3.0-or-later" to "Apache-2.0 WITH LLVM-exception". Note that for the abigail.m4, tests/test-dot.cc and tests/test-svg.cc the change was from "GPL-3.0-or-later WITH GCC-exception-3.1" to "Apache-2.0 WITH LLVM-exception". include/abg-cxx-compat.h was changed from "LGPL-2.0-or-later" to "Apache-2.0 WITH LLVM-exception". Source code of programs (as opposed to source code of the library) where generally licensed under GPL-3.0-or-later; they are also now licensed "Apache-2.0 WITH LLVM-exception".

Replace individual license references with SPDX Identifiers
This patch replaces license headers with SPDX identifiers in all files containing license headers. For each file, the SPDX identifier formally represents its current license. Note that the list of SPDX identifiers is available on the SPDX web site at https://spdx.org/licenses. For autoconf-archive/ax_prog_python_version.m4 however, there is a little catch. Dodji Seketeli wrote this ax_check_python_modules.m4. Just like the other autoconf-archive macros, it makes sense to have it under the FSF All Permissive license. Actually, the terms of that license was already in the file but then the license header was wrongly set to GPLv2 with autoconf exception. So I fixed that in this commit by setting the SPDX identifier to FSFAP. * abigail.m4: Replace the license header with the SPDX identifier GPL-3.0-or-later WITH GCC-exception-3.1 * autoconf-archive/ax_check_python_modules.m4: Correctly set the SPDX identifier to FSFAP. * autoconf-archive/ax_compare_version.m4: Replace the license header with the SPDX identifier FSFAP. * autoconf-archive/ax_prog_python_version.m4: Likewise. header with the SPDX identifier FSFAP. * autoconf-archive/ax_valgrind_check.m4: Likewise. * gen-changelog.py: Replace the license header with the SPDX identifier LGPL-2.0-or-later. * include/abg-comp-filter.h: Replace the license header with the SPDX identifier LGPL-3.0-or-later. * include/abg-comparison.h: Likewise. * include/abg-config.h: Likewise. * include/abg-corpus.h: Likewise. * include/abg-cxx-compat.h: Replace the license header with the SPDX identifier LGPL-2.0-or-later. * include/abg-diff-utils.h: Replace the license header with the SPDX identifier LGPL-3.0-or-later * include/abg-dwarf-reader.h: Likewise. * include/abg-fwd.h: Likewise. * include/abg-hash.h: Likewise. * include/abg-ini.h: Likewise. * include/abg-interned-str.h: Likewise. * include/abg-ir.h: Likewise. * include/abg-libxml-utils.h: Likewise. * include/abg-libzip-utils.h: Likewise. * include/abg-reader.h: Likewise. * include/abg-regex.h: Likewise. * include/abg-reporter.h: Likewise. * include/abg-sptr-utils.h: Likewise. * include/abg-suppression.h: Likewise. * include/abg-tools-utils.h: Likewise. * include/abg-traverse.h: Likewise. * include/abg-viz-common.h: Likewise. * include/abg-viz-dot.h: Likewise. * include/abg-viz-svg.h: Likewise. * include/abg-workers.h: Likewise. * include/abg-writer.h: Likewise. * install-sh: Replace the license header with the SPDX identifier MIT. * ltmain.sh: Replace the license header with the SPDX identifier GPL-2.0-or-later.

Support having several debuginfo search dirs for a binary
There are use cases where the split debuginfo file of a given binary
is under a given root directory and that the split debuginfo file
itself depends on an alternate debuginfo file that is under another
unrelated root directory.
In that case, the dwarf reader must be able to look for the debuginfo
files under several unrelated root directories. The tools abidiff and
abidw must thus support having several occurences of the option
--debug-info-dir1 (or --debug-info-dir2) meaning that the debuginfo
files for the binary must be looked for under several root
directories.
This is what this patch does.

Add option to avoid walking abigail::ir nodes twice
When the ir_traversable_base::traverse() walks the IR graph, it
happens that it can visit a type node that was already visited before.
For instance, it visits the 'struct S' once and later, as part of its
visit of struct S*, it can visit struct S again.
There are use cases where we want the walker to avoid visiting a given
type node again. This patch adds the option to do so.
Basically the ir_node_visitor class can now be configured to tell the
walker to avoid re-visiting a node.
The test-ir-walker.cc example is amended to avoid re-visiting type nodes
as well.
* include/abg-ir.h (struct ir_node_visitor): Make this be a class.
Add a private data member to it, following the 'pimpl' idiom.
(ir_node_visitor::{allow_visiting_already_visited_type_node,
mark_type_node_as_visited, forget_visited_type_nodes,
type_node_has_been_visited}): Declare new member functions.
* src/abg-ir.cc ({type_base, type_decl, scope_type_decl,
qualified_type_decl, pointer_type_def, reference_type_def,
array_type_def, enum_type_decl, typedef_decl, class_or_union,
class_decl, union_decl}::traverse): Avoid re-visiting the type
node if the visitor was configured as such.
(struct ir_node_visitor::priv): Define new struct.
(ir_node_visitor::{allow_visiting_already_visited_type_node,
mark_type_node_as_visited, forget_visited_type_nodes,
type_node_has_been_visited}): Define new member functions.
* tests/test-ir-walker.cc
(name_printing_visitor::name_printing_visitor): Avoid visiting a
type node twice.

Introduce the concept of environment
There are resources needed by the type system and other artifacts of
libabigail. Today, when the life time of those resources need to be
greater than all of artifacts of Abigail, then said resources are made
global.
But then global resources are not great, if anything because they
complicate the future use of the library in concurrent computing
setups.
As I was in the need to add one resource to be used by the type
system, I decided to sit down and first overhaul how these long lived
resources needed to be handled.
And here comes the concept of "environment". An environment is a
place where one can put resources that need to live longer than all
the other artifacts of the Abigail system. And so, the code that
creates Abigail artifacts needs and environment of for said artifacts
to use. In other words, artifacts now use an environment.
This has interesting and strong implications. We can only compare two
artifacts if they use the same environment. This is quite a strong
requirement.
But then when this requirement is fulfilled, comparing two types
amounts to just comparing two pointer values; hash values for types
can also be cached. Now *that* is great for speed of comparison, is
it not?
This patch introduce the concept environment (which is basically a new
abigail::ir::environment type), removes the global variables and uses
the environment instead. Each ABI artifact (either type or decl) now
has a ::get_environment() member function to get its environment.
This patch also disables the caching of hash values because the
caching must happen only *after* all types have been canonicalized.
We were not respecting that requirement until now, and that introduces
wrong hash values. A subsequent patch is going to re-introduce hash
value caching again, once the infrastructure is in place to set a flag
in the environment (hah!) once type canonicalization is done, and then
later read that flag when some client code requests a hash value, to
know if we should look in the hash value cache or not.
The patch obviously changes the output of numerous regression tests
(if anything b/c it disables hash value caching) so 'make check'
yields regressions. But then, it's only the subsequent patch that
updates the tests.

Handle the life time of the map of canonical types
While working on something else, it turned out that we need to cleanup (de-allocate) the map of canonical types when all the translation units that own types are de-allocated. Otherwise, when new translation units are created later, the types in the canonical types map become unrelated to the types in these new translation units, leading to memory management issues. This patch introduces a "usage watchdog" which detects when no translation unit uses the type system anymore. That usage watchdog is then used in the destructor of the translation_unit type to de-allocate the global data that is logically owned by by the type system. The patch also changes the API to read translation units and corpora in a way that forces users to get a handle on the resulting shared pointer. * include/abg-ir.h (type_base::canonical_types_map_type): Move this typedef into abg-ir.cc and out of the type_base namespace.

Canonicalize types either early or late after TU reading
While trying to diff two identical files (abidiff foo.so foo.so) it
appeared that canonicalizing types during e.g, the DWARF reading
process was leading to subtle errors because it's extremely hard to
know when a type is complete. That is, during the building of a class
type C, a pointer to C can be built before C is complete. Worse, even
after reading the DIE (from DWARF) of class C, there can be DIE seen
later in the translation unit that modifies type C. In these late
cases, one needs to wait -- not only until C is fully built, but also
sometimes, after the translation unit is fully built -- to
canonicalize C and then the pointer to C. This kind of things.
So now there are two possible points in time when canonicalization of
a type can happen. It can happen early, when the type is built. This
is the case for basic types and composite types for which all
sub-types are canonicalized already. It can happen late, right after
we've finished reading the debug info for the current translation
unit.
So this patch fixes the IR traversal and uses that to walk the
translation unit (or even types) after it's built. It does away with
the first attempt to perform early canonicalizing only.
The patch also handles type canonicalizing while reading xml-abi
format.
* include/abg-fwd.h (is_class_type)
(type_has_non_canonicalized_subtype): Declare new functions.
(is_member_type): Remove the overload that takes a decl_base_sptr.
It's superfluous. We just need the one that takes a
type_base_sptr.
* include/abg-ir.h (translation_unit::{is_constructed,
set_is_constructed}): Add new methods.
(class_decl::has_virtual_member_functions): Likewise.
(class decl_base): Makes it virtually inherit ir_traversable_base.
(class type_base): Make this virtually inherit traversable_base
too.
(type_base::canonicalize): Renamed enable_canonical_equality
into this.
(type_base::traverse): Declare new virtual method.
(canonicalize): Renamed enable_canonical_equality into this.
(scope_type_decl::traverse): Declare new virtual method.
(namespace_decl::get_pretty_representation): Declare new virtual
method.
(function_type::traverse): Likewise.
(class_decl::base_spec::traverse): Likewise.
(ir_node_visitor::visit): Remove the overloads and replace each of
them with a pair of ...
(ir_node_visitor::{visit_begin, visit_end}): ... of these.
* include/abg-traverse.h (traversable_base::visiting): New
method.
(traversable_base::visiting_): New data member.
(traversable_base::traversable_base): New constructor.
* src/abg-ir.cc ({scope_decl, type_decl, namespace_decl,
qualified_type_def, pointer_type_def, reference_type_def,
array_type_def, enum_type_decl, typedef_decl, var_decl,
function_decl, function_decl::parameter, class_decl,
class_decl::member_function_template,
class_decl::member_class_template, function_tdecl,
class_tdecl}::traverse): Fix this to properly set the
traversable_base::visiting_ flag and to reflect the new signatures
of the ir_node_visitor methods.
({type_base, scope_type_decl, function_type,
class_decl::base_spec}::traverse): New method.
(type_base::get_canonical_type_for): Handle the case of the type
already having a canonical type. Properly hash the type using the
dynamic type hasher. Look through declaration-only classes to
consider the definition of the class instead. Fix logic to have a
single pointer of return, to ease debugging.
(canonicalize): Renamed enable_canonical_equality into this.
(namespace_decl::get_pretty_representation): Define new method.
(ir_node_visitor::visit): Replace each of these overloads with a
pair of visit_begin/visit_end ones.
(translation_unit::priv::is_constructed_): New data member.
(translation_unit::priv::priv): Initialize it.
(translation_unit::{is_constructed, set_is_constructed}): Define
new methods.
(is_member_type(const decl_base_sptr)): Remove.
(is_class_type(decl_base *d)): Define new function.
(class_decl::has_virtual_member_functions): Define new method.
(equals(const class_decl&, const class_decl&, change_kind*)): If
the containing translation unit is not constructed yet, do not
take virtual member functions in account when comparing the
classes. This is because when reading from DWARF, there can be
DIEs that change the number of virtual member functions after the
DIE of the class. So one needs to start taking virtual members
into account only after the translation unit has been constructed.
(class non_canonicalized_subtype_detector): Define new type.
(type_has_non_canonicalized_subtype): Define new function.
* src/abg-corpus.cc (symtab_build_visitor_type::visit): Renamed
this into symtab_build_visitor_type::visit_end.
* src/abg-dwarf-reader.cc (die_type_map_type): New typedef.
(die_class_map_type): This is now a typedef on a map of
Dwarf_Off/class_decl_sptr.
(read_context::{die_type_map_, alternate_die_type_map_,
types_to_canonicalize_, alt_types_to_canonicalize_}): New data
members.
(read_context::{associate_die_to_decl,
associate_die_to_decl_primary}): Make these methods public.
(read_context::{associate_die_to_type,
lookup_type_from_die_offset, is_wip_class_die_offset,
types_to_canonicalize, schedule_type_for_canonicalization}):
Define new methods.
(build_type_decl, build_enum_type)
(build_class_type_and_add_to_ir, build_qualified_type)
(build_pointer_type_def, build_reference_type, build_array_type)
(build_typedef_type, build_function_decl): Do not canonicalize
types here.
(maybe_canonicalize_type): Define new function.
(build_ir_node_from_die): Take a new flag that says if the ir node
is a member type/function or not. Early-canonicalize base types.
Canonicalize composite types that have only canonicalized
sub-types. Schedule the other types for late canonicalizing. For
class types, early canonicalize those that are non-member types,
that are fully constructed and that have only canonicalized
sub-types. Adjust to the new signature of build_ir_node_from_die.
(get_scope_for_die, build_namespace_decl_and_add_to_ir)
(build_qualified_type, build_pointer_type_def)
(build_reference_type, build_array_type, build_typedef_type)
(build_var_decl, build_function_decl): Adjust for the new
signature of build_ir_node_from_die.
(build_translation_unit_and_add_to_ir): Likewise. Perform the
late canonicalizing of the types that have been scheduled for
that.
(build_class_type_and_add_to_ir): Return a class_decl_sptr, not a
decl_base_sptr. Adjust for the new signature of
build_ir_node_from_die. Early canonicalize member types that are
created and added to a given class, or schedule them for late
canonicalizing.
* src/abg-reader.cc (class read_context::{m_wip_classes_map,
m_types_to_canonicalize}): New data members.
(read_context::{clear_types_to_canonicalize,
clear_wip_classes_map, mark_class_as_wip, unmark_class_as_wip,
is_wip_class, maybe_canonicalize_type,
schedule_type_for_late_canonicalizing,
perform_late_type_canonicalizing}): Add new method definitions.
(read_context::clear_per_translation_unit_data): Call
read_context::clear_types_to_canonicalize().
(read_translation_unit_from_input): Call
read_context::perform_late_type_canonicalizing() at the end of the
function.
(build_function_decl): Fix the function type canonicalizing (per
translation) that was already in place. Do the canonicalizing of
these only when the type is fully built. Oops. This was really
brokend. Also, when the function type is constructed, consider it
for type canonicalizing.
(build_type_decl): Early canonicalize basic types.
(build_qualified_type_decl, build_pointer_type_def)
(build_pointer_type_def, build_reference_type_def)
(build_array_type_def, build_enum_type_decl, build_typedef_decl):
Handle the canonicalizing for these composite types: either early
or late.
(build_class_decl): Likewise. Also, mark this class a 'being
built' until it's fully built. This helps the canonicalizing code
to know that it should leave a class alone until it's fully built.
* tests/test-ir-walker.cc (struct name_printing_visitor): Adjust
to the visitor methods naming change.
* configure.ac: Generate the tests/runtestcanonicalizetypes.sh
testing script from tests/runtestcanonicalizetypes.sh.in.
* tests/runtestcanonicalizetypes.sh.in: Add the template for the
new runtestcanonicalizetypes.sh script that test for type
canonicalizing.
* tests/Makefile.am: Add the new runtestcanonicalizetypes.sh
regression testing script to the build system.
