[dwarf-reader] Handle per translation-unit type de-duplication
Until now, when the elf/dwarf reader builds ABI artifacts, it performs
type de-duplication by considering that a type with a given name should
be defined only once in a given ABI corpus. This is per-corpus
de-duplication.
The problem with that approach is that it assumes that the binary
respects the One Definition Rule[1], aka ODR. But then many non-C++
binaries don't respect the ODR.
So, for non-c++ binaries, we shouldn't assume the ODR. We should be
able to assume a per translation unit (aka per-tu) de-duplication.
That is, consider that a type with a given name is defined just once
in a given translation unit. Or perform no de-deplication at all,
depending on the kind of type we are looking at.
And this is what this patch does. It allows the ELF/DWARF reader to
perform per-tu type de-duplication by assuming that it's only in a given
translation unit that a type definition must be unique. It also allows it
perform no de-duplication at all for some kind of types.
In practice, function types are de-duplicated on a per-tu basis if ODR
is not relevant, otherwise, they are de-duplicated on a per-corpus
basis when ODR is relevant.
For most of the other types, if ODR is not relevant, then no
de-duplication is performed at all. Otherwise, for these types, if
ODR is relevant, per-corpus de-duplication is performed.

(read_context::clear_per_translation_unit_data): Clear the new
read_context::per_tu_name_artefacts_map_.

Handle per translation unit and per corpus types maps
Today, whenever a type is added to its scope, a map that associates the qualified type name to the type is updated. There is only one such map in a given ABI corpus. So whenever a type is looked up from its name, it's that per-corpus type map that is used. This setup makes libabigail type lookup be tailored only for binaries that respect the One Definition Rule of C++[1] (aka ODR) which basically says that there should be only one type of a given name in an ABI corpus. It turns out that many binaries, especically C binaries, don't respect the ODR. So a type "struct foo" can be defined in a file a.c and another *different* type "struct foo" can also be defined in b.c. What a useful and safe feature! Not. For those binaries, just having one type map doesn't work. We need to have one type map per translation unit, and one map per-corpus map. This is the strategy implemented by this patch. With this patch, whenever a type is added to its scope, a per translation unit type map is updated. The per corpus map is updated as well. If there are more than one type of a given name, the entry in the per corpus type map for that type is left empty. Type lookup now potentially becomes a two phases lookup. Whenever a type is looked up from its name, the per corpus type map is looked at first. If the type is not in that per corpus type map, then the per translation unit type maps are lookup up, in sequence. The patch thus re-visits the type maps updating and lookup routines to adapt them to the new scheme. The patch also updates the clients of the type map updating and lookup code. Note that this patch is part of a series of patches which aims to move libabigails away from its ODR-centric organization to make it work well also on binary where the ODR is not relevant. As such, the patch doesn't assure that "make check" passes. To have "make check" pass, you need to have all the patches of the series applied.

Naming typedefs of classes are not read properly from abixml
When loading a class from abixml and when that class has a naming typedef, build_class_decl fails to build the naming typedef from its ID because it calls read_context::get_type_decl() instead of read_context::build_or_get_type_decl(). This patch fixes that issue by using read_context::build_or_get_type_decl rather than read_context::get_type_decl. Also, as read_context::build_or_get_type_decl can trigger the creation of a class (and recursively call build_class_decl), it needs to be called after the class type being built is marked as work-in-progress (aka WIP). So the handling of the naming typedef is moved to after the class type being built is marked as WIP. * src/abg-reader.cc (build_class_decl): Use read_context::build_or_get_type_decl rather than read_context::get_type_decl to build the naming typedef referred to by the class being built. Move the handling of naming typedefs after the class is marked as WIP and keyed. Signed-off-by: Dodji Seketeli <dodji@redhat.com> |

Don't early-canonicalize function types when reading abixml
When reading from an abixml file, we sometimes canonicalize function types before the entire abixml file is read. This can lead to, e.g, a function type that is not yet fully built being canonicalized too early and so its canonical type being wrong because it reflects the state of the function type at canonicalization time -- but then that state changed later. This patch fixes that by forcing us to late-canonicalize function types, just like we do for all aggregate types. * src/abg-reader.cc (read_context::maybe_canonicalize_type): late-canonicalize function types too.

Bug 20380 - Compare two local RPMs
Bug 20270 is also fixed.

fedabipkgdiff some/place/foo.rpm another/place/bar.rpm
But, network is still needed to talk with Koji.
This patch also introduces new terms for libabigail, that is the
subject, ancillary package, and comparison half. Subject represents a
package that is subject of the ABI comparison, a subject could be a RPM

Fix aborting when reading .foo symbols from a ppc64 binary
On ppc64, the value of a function symbol is *usually* the pointer to the function. That function pointer value refers to an index inside the ".opd" (Official Procedure Descriptor) section. That section is a record of tripplets values. One of these values is the address of the entry point of the function. A debug information entry for a function, in DWARF, refers to the entry point of the function; not to the function pointer address. So libabigail builds a table that associates a function entry point address to its function pointer address. So, if a function is named "foo", it has an entry in the symbol table for the symbol name "foo"; the value of that symbol is the function pointer address of foo, which refers to an offset in the ".opd" section. But then it turns out that there is also going to be an entry in the symbol table for an artificial symbol named ".foo". Pleast note the dot before the suffix "foo". The value of the ".foo" symbol is the address of the entry point of the function "foo"; it's an address in the ".text" section this time. Libabigail's ELF symbols reading code was (wrongly) expecting all entries in the symbol table that refer to function to have values that are offset in the ".opd" section.

In that case, if the name of the symbol is "foo", the name of the symbol which value is directly the entry point address is ".foo".

Bug 20927 - Segfault when $HOME is not set
When comparing two binaries with abi{pkg}diff, if $HOME is not set, we
segfault at some places because we don't expect that. I ran "make
check" after doing "unset HOME" to help me catch most of those places.
This patch updates the code to handle that case.
* src/abg-tools-utils.cc
(get_default_user_suppression_file_path): Handle the case where
the HOME environment variable is not set.
* tools/abipkgdiff.cc (package::extracted_packages_parent_dir):
Likewise. When $HOME is empty set then use $TMPDIR. If it's
empty too then use "/tmp".

Bug 20887 - Show relative change of offsets
Until now, an offset change is reported by showing the old and new
offsets of the data member that changed.
This patch adds the string "(by +N bits)" with 'N' being the number of
bits by which the offset of the data member was increased, or "(by -N
bits) if the offset of the data member was decreased of N bits.
The patch also emits a string that says "size hasn't changed" if the
size of the structure did not change.
This can be disabled by a new --no-show-relative-offset-changes
option.

Introduce on-the-fly type canonicalization
During canonicalization of a type T, when T is structurally compared
to an already canonicalized type C, it can happen that
non-canonicalized sub-types of T are structurally compared again and
again to canonicalized sub-types of C.
This patch introduces a new optimization or those cases: on-the-fly
type canonicalized.
That means, if a not-yet-canonicalized sub-type S of the type T being
canonicalized structurally compares equal to a canonicalized sub-type,
then the canonical type of S is said to be the canonical type of the
canonicalized sub-type. So sub-type S is canonicalized, on-the-fly,
during canonicalization of type T.
This considerably speeds up the canonicalization process while doing
"abidiff vmlinux vmlinux". It goes from taking forever to taking 45
seconds on a non-optimized build.

Fix pretty representation of array types
It turned out we were wrongly emitting the pretty representation of array types in two cases: 1/ in case of qualified array types: a const array of string type was being pretty-represented as: "const string[]" instead of "string[] const". 2/ in case of array with an empty sub-range DIE; that is a sub-range DIE with no attribute at all. For instance an array of char with an empty sub-range DIE was being represented as: "char", instead of "char[]". This patch fixes 1 and 2. It also updates numerous test reference output files. * include/abg-ir.h (array_type_def::is_infinite): Fix indentation. * src/abg-ir.cc (qualified_type_def::build_name): An empty set of sub-ranges for a vector is represented by "[]".

Support naming typedef and use them to speed up type canonicalization
There is a common C idiom in which an anonymous struct is named using
a typedef:
typedef struct {int member;} anonymous_struct_type;
The typedef name "anonymous_struct_type" becomes the name of the
otherwise anonymous struct. That is what a naming typedef is.
So, the nice thing about naming typedefs is that an anonymous class
type suddenly becomes non anymous. So that type becomes eligible to
the ODR-based optimization during type canonicalization. That speeds
up type canonicalization, at least for 'abidw'.
This patch represents naming typedefs for class_decl types in the
internal representation. The patch also changes the meaning of an
anonymous class. Whenever such a class becomes named by a typedef,
the class is not considered anonymous anymore, at least for the
purpose of type canonicalization.

Implement de-duplication for types and decls at DWARF loading time
Many types and decls are redefined in every translation unit that make
up an ELF binary. This patch detects that a DIE represents a type or
decl that has already been defined in the current corpus and so will
not create a new internal representation for it.
The patch defines facilities to build the pretty representation of a
type or decl. It's by looking at the pretty representation of a DIE
that the patch detects that a different DIE has already defined the
same type or decl.
The patch also fixes detection of the const-ness of member functions
as there were many cases where const member functions were not
recognized as const. This fix makes it so that the pretty
representation of the DIE of said member functions match the pretty
representation of their internal representation, as far as the
const-ness is concerned.
One bit of infrastructure change that is used by the const-ness fix is
that method_type now carries const-ness. So a method_decl that has a
const method_type is going to be const itself.

Setup per-corpus type maps indexed by type names
This patch creates per-corpus maps that associate, for a certain kind
of type, the fully qualified name of the type to the type.
So there is a map for class_decl, one for enum_type_decl, one for
type_decl, etc.
These maps are populated when a new type is added to its scope.
The patch defines overloads of the function
maybe_update_types_lookup_map() that update the right map, depending
on the kind of type we are looking at.
Note that there also is a map in each class that associates a
signature string to a member functions. This is so that member
functions of a given class can be looked up by signature.
This is so that looking up a type becomes now much faster than having
to walk all the translation units of a corpus to find one.
Note that this patch is specifically part of the series of patches
that implements types and declarations de-duplication while reading
DWARF information.
The patch might slightly change the output of abi serialization or
comparison so it needs some adjustments of some test reference files.
That adjustment is not done here. Rather, it's done at once in
another patch of the set.

A suppressed diff node implies suppressing all equivalent nodes too
When a diff node N is suppressed (for instance, using the
--headers-dir{1,2} option of abidiff}, it's only that diff node that
is suppressed. We forget to suppress diff nodes that are equivalent
to N.
Here is why we forget to suppress diff ndoes that are equivalent.
apply_suppressions walks the diff node graph to mark diff nodes as
suppressed. But it does the walking by making sure each diff node's
*class of equivalence* is visited once. This is not only a way to
prevent infinite loops while visiting the graph, but also an
optimization as it avoids walking two equivalent diff nodes.
But then it can happen that we forget to categorize some diff nodes
inside a given class of equivalence, even though we categorized some
others.
This patch makes it so that when a diff node inside a class of
equivalence is categorized as SUPPRESSED, the canonical diff node of
that class of equivalence is categorized as SUPPRESSED too. That way,
to know if a diff node is suppressed, we just need to look at its
canonical diff node.
While doing this, I noticed that abidiff and abipkgdiff are not
dropping private types from libabigail's internal representation, even
though the Library now has that capability. The patch fixes that.
But then the patch adds a --dont-drop-private-types option to abidiff
to avoid dropping those private types from the IR, so that regression
tests can make sure that a suppressed diff node implies suppression
all equivalent nodes too.

Support reading data member offset from DW_AT_bit_offset
There are times where the DW_AT_data_member_location attribute is set to zero and where the actual offset of the data member is the value of the DW_AT_bit_offset. This seems to be happening when a union type is involved. To get the offset of a data member, this patch makes us read the DW_AT_bit_offset when it's present. Otherwise, it gets the offset from the DW_AT_data_member_location as we used to do. In the passing the patch fixes the offset of base classes; the nubmer of bytes value was what was being used, rather than the number bits value. * src/abg-dwarf-reader.cc (die_member_offset): Better comments. Support reading the bit offset also from the DW_AT_bit_offset attribute when it's present. Make sure this always returns a value in bits. (build_class_type_and_add_to_ir): No need to multiply (by 8) the value returned by die_member_offset anymore because it's now in bits directly. * tests/data/test-diff-filter/test30-pr18904-rvalueref-report0.txt: Adjust. * tests/data/test-diff-filter/test30-pr18904-rvalueref-report1.txt: Adjust. * tests/data/test-read-dwarf/test1.abi: Adjust. * tests/data/test-read-dwarf/test11-pr18828.so.abi: Adjust. * tests/data/test-read-dwarf/test12-pr18844.so.abi: Adjust. * tests/data/test-read-dwarf/test13-pr18894.so.abi: Adjust. * tests/data/test-read-dwarf/test14-pr18893.so.abi: Adjust. * tests/data/test-read-dwarf/test15-pr18892.so.abi: Adjust. * tests/data/test-read-dwarf/test16-pr18904.so.abi: Adjust. * tests/data/test-read-dwarf/test17-pr19027.so.abi: Adjust. * tests/data/test-read-dwarf/test19-pr19023-libtcmalloc_and_profiler.so.abi: Adjust. * tests/data/test-read-dwarf/test21-pr19092.so.abi: Adjust. * tests/data/test-read-dwarf/test22-pr19097-libstdc++.so.6.0.17.so.abi: Adjust.

Until now, when reporting about struct or union changes, data members were sorted by using their offset; the data member with the smallest offset coming first.

Support union types
This patch makes Libabigail understand C and C++ union types. It
defines a new class abigail::ir::union_decl to represent the
declaration of a union type. It also defines a new type
abigail::comparison::union_diff to represent the changes between two
union types. The patch then adds facilities to read union types from
DWARF and abixml and also to write union types into the abixml format.
As union types and class types have a lot in common, the patch tries
very hard to share code between the abigail::ir::class_decl and
abigail::ir::union_decl. To do so, a new class
abigail::ir::class_or_union is created. It's the base class for both
abigai::ir::class_decl and abigail::ir::union_decl. Its data members
and methods represent the set of data and behaviour that are common to
classes and unions. A lot of code and data that were initially in
abigail::ir::class_decl got moved into the new
abigail::ir::class_or_union class.
Similary, the patch creates a new class
abigail::comparison::class_or_union_diff that is a base class for both
the existing class abigail::comparison::class_diff and the newly
created class abigail::comparison::union_diff. The new class
abigail::comparison::class_or_union_diff contains data and behaviour
that are common to both union_diff and class_diff and that were
previously in class_diff.
The rest of the patch is mostly adjustment so that code that was
supposed to work with class class_decl only can now work with class
class_or_union when it makes sense. Similarly for class_diff and
class_or_union_diff.
The patch adds regression tests into the test suite and adjust many
existing tests involving binaries that contain union types; the
reference output of those tests now take union types into account.

Support empty properties in INI files
The ini file parser doesn't support parsing properties with no value.
This patch adds that feature, as it turned out to be a pre-requisite
for reading Linux Kernel ABI whitelist files.

constructor for empty values.
(simple_property::has_empty_value): Declare new member function.
* src/abg-ini.cc (simple_property::{simple_property,
has_empty_value}): Define new member functions.
(read_context::read_property): Support reading a property with no
value.
(write_property_value, write_property): Support writting a
property with empty value.
