2015-06-07 Dodji Seketeli <dodji@redhat.com>
Build libabigail tools as position-independent code
* tools/Makefile.am: Compile the binaries here with -fPIC. Note
that the library libabigail.la is built with libtool which already
takes care of this, so no need to worry about this for
libabigail.la.

update-changelog.
2015-06-07 Dodji Seketeli <dodji@redhat.com>
Avoid infinite loop in elf_symbol::get_alias_from_name()

(elf_symbol::get_alias_which_equals): Test for the next alias
pointing to the main symbol, in the loop exit condition.
2015-06-04 Dodji Seketeli <dodji@redhat.com>
Change the linkage name only when necessary
* include/abg-ir.h (elf_symbol::get_alias_from_name): Declare new
member function.
* src/abg-ir.cc (elf_symbol::get_alias_from_name): Define it.
* src/abg-dwarf-reader.cc (build_var_decl, build_function_decl):
Once the linkage name is supposed to contain the value of the
DW_AT_linkage_name attribute, set it the name of the underlying
symbol only if value of DW_At_linkage_name is missing or different
from the names of all the aliases of the underlying symbol.
* tests/data/test-read-dwarf/test2.so.abi: Adjust.
2015-06-04 Dodji Seketeli <dodji@redhat.com>
Various white space cleanups
* include/abg-comparison.h: Remove various useless vertical white
spaces.

Cleanup logic in class_diff::ensure_lookup_tables_populated()
* src/abg-comparison.cc
(class_diff::ensure_lookup_tables_populated): Remove the code that
tries to lookup allegedly added functions from the set of deleted
ones, by using the pretty printed name of the function. Handling
the case of a function decl not correctly tied to it symbol is
handled my generically a bit later in this function.

type_suppression::get_reach_kind() to determine if the suppression
specification suppresses a given diff node.

members.
(redundancy_marking_visitor::visit_begin): So if the current diff
node has already been visited, but if the previously visited node
has been filtered out, then do not mark this node as being
redundant. And mark the current diff node as being the last
visited one in its class of equivalence.
(categorize_redundancy): Clear the map of diff nodes visited per
class of equivalence.

Fix redundancy marking for change of types used directly
* include/abg-comparison.h (pointer_map): Make this be a map of
{size_t, size_t} pairs, rather than {size_t, bool}, so that each
pointer in the map can be associated to another one.
(diff_context::diff_has_been_visited): Return the pointer to the
first diff node of the equivalence class that has been visited.
* src/abg-comparison.cc (is_pointer_diff, is_reference_diff)

visited.
(redundancy_marking_visitor::visit_begin): If a diff node is a
child node of a function parameter diff or base diff node and if
it's not a pointer or reference diff node, then do not mark it as
redundant. Also, make sure to not mark the first diff node of a
given class of equivalence that has been visited, as redundant;
only the other subsequent nodes should be marked redundant; we
were hitting this case because of an optimization that makes
equivalent class diff nodes to share their private (pimpl) data.

Fix canonicalizing of member types ... *AGAIN*
* src/abg-dwarf-reader.cc (build_ir_node_from_die): For typedefs,
we don't need to test that the current scope is a class to know
that we are looking at a member type. Just looking at the
is_member flag is enough.
So the issue arises when for instance, we are reading a class that
defines a member typedef (or enum) and uses that enum as the type of a
data member. When reading that data member (before reading the
definition of the typedef), we read the type of the data member; so we
hit the typedef. But build_ir_node_from_die() cannot fully construct
the scope of the typedef before handing off the typedef because we are
currently building it! So it hands out a non-complete version of the
class that is being built; 'is_member' is not set to 'true' because
we are getting the type of the data member; it's not *necessarily* a
member type. So we need to check !is_class_type(scope) to know if we
are given a member type. I am now thinking that the "is_member" flag
is actually useless. I think I'll remove it in a later patch.
Anyway, this fixes 'abidiff libabigail.so libabigail.so' again. I
have some stashed patches that brings it's time down to ~ 45 seconds.
So we are getting close to being able to include that *ultimate* test in
regression test suite. Oh well.
* src/abg-dwarf-reader.cc (build_ir_node_from_die): When building
typedefs, enum and memeber classes, check that the scope is a
member class to detect if we are building a member type. In which
case the caller is going to handle the canonicalizing of the
member type *after* it's access specification has been adjusted.
Otherwise, that adjustments happens after the type has been
canonicalized and bad things happen at comparison type.

Fix handling of canonicalizing of member enum types

(build_reference_type, build_typedef_type)
(build_class_type_and_add_to_ir): Take a new flag that says if the
DIE is from the alternate debug info section or not. Perform the
DIE->type association in these functions. Note that in
build_class_type_and_add_to_ir we are now doing the DIE->type
association even for declaration-only classes. And for member
types, do not bother doing the association because it's already
been done by build_ir_node_from_die().
(build_ir_node_from_die): Do not do the DIE->type association here
anymore. Adjust to the new signature of the build_* functions
above that actually build the types.

lookup_type_from_die_offset}): use the new die_type_map()
accessor.
(read_context::clear_per_translation_unit_data): Factorize this
from build_translation_unit_and_add_to_ir(). Also, add code to
clear the DIE->type map as well as the vectors of offsets of the
types of the DIEs to canonicalize after the translation unit has
been read.

the containing translation unit is not constructed yet, do not
take virtual member functions in account when comparing the

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.

(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

for type canonicalizing.

Handle the canonicalizing for these composite types: either early

* tests/data/test-alt-dwarf-file/test0-debug-dir/.build-id/16/7088580c513b439c9ed95fe6a8b29496495f26.debug:
Make this be a real file, no more a symlink to
../../../test0-common-dwz.debug.
* tests/data/test-alt-dwarf-file/test0-report.txt: Now that the
file above is no more a symlink the message emitted by the test
changes. It now says that the file found is the base name of the
real file. So change the reference report accordingly.

Use the POSIX 1003.1-1988 tar format for dist tar
* configure.ac: For the tar invocation made by make dist, make
sure to use the POSIX 1003.1-1988 tar format that can support file
names of more than 99 characters. This is useful for the
test-alt-dwarf-file test that has data made of a file which patch
has more than 99 characters.
2014-11-19 Dodji Seketeli <dodji@redhat.com>
Nested automake conditionals don't work
* configure.ac (ENABLE_ZIP_ARCHIVE_AND_CXX11): Define this
automake condition variable that is true if both the zip archive
and c++11 features are enabled. This is important to know if the
test runtestdot is going to be compiled. That test needs both
c++11 and the zip archive features.
* tests/Makefile.am: Do not nest automake conditional statements.
It does not work. Rather, use the new
ENABLE_ZIP_ARCHIVE_AND_CXX11 condition variable.

beginning of a ChangeLog entry body, do not expect a line that
starts with a '*' to end with a ':' because there can be long file
names that end on the next line.
2014-11-18 Dodji Seketeli <dodji@redhat.com>
Allow introductory text in commit log and ignore it when generating ChangeLog
* gen-changelog.py (process_commit): Everything that comes between
the subject line of the commit and the first \t* sequence is
considered to be introductory text. Ignore it when generating the
ChangeLog entry.

reflect the fact that we can now have introductory text in the
commit log.
2014-11-18 Dodji Seketeli <dodji@redhat.com>

Initial support for function suppressions
* include/abg-comparison.h (enum visiting_kind): Change the
meaning of this. It was to determine if traversal was to be done
in a pre or post manner. But with the recent addition of
diff_node_visitor::visit_{begin,end}() notifiers, the pre/post
handling is taken care of in a different way. So now the meaning
of this enum is changed to handle whether diff node children
should be visited or not. So the enumerators are now
DEFAULT_VISITING_KIND, and SKIP_CHILDREN_VISITING_KIND. And it's
a bit-field.
(operator{&,~}): Declare more bit manipulation operators for the
enum visiting_kind.
(function_suppression_sptr, function_suppressions_type): New
typedefs.
(function_suppression, function_suppression::parameter_spec):

visiting_kind change. Value-initialize the visiting_kind_ data
member.

(class function_suppression::parameter_spec::priv): Define new
type.
(function_suppression::parameter_spec::*): Define the member
functions of the new function_suppression::parameter_spec type.
(class function_suppression::priv): Define new type.
(function_suppression::*): Define the member functions of the new
function_suppression type.
(diff::traverse): There is no more {PRE,POST}_VISITING_KIND
enumerator. So nuke the code that was dealing with it.
(redundancy_marking_visitor::skip_children_nodes_): New data
member flag.
(redundancy_marking_visitor::visit_begin): If the current diff
node is not be reported (is filtered out), do not bother visit its
children nodes for the purpose of marking redundant nodes. So use
the new skip_children_nodes_ flag above to know we are in that case.
(redundancy_marking_visitor::visit_end): Unset the new
skip_children_nodes_ flag above when appropriate.
* include/abg-fwd.h (is_function_decl): Declare new function.
* include/abg-ir.h

account when trying to detect that the first parameter of a member

a non static member function.

to store the name of the lhs of the class and the rhs into the
lhs. Also, when we bail out because we detect that there is a
comparison underway, do *not* unmark the current class as not being
involved in the comparison. Also, break at the first lhs virtual
member function that is different from the rhs counter part.

clone of a function that implements an interface (this happens for
destructors, for instance). In this case, really do the cloning
of the interface implementation. If the cloned function happens
to be member function, use finish_member_function_reading to read
the properties relevant to its method-ness.

not installed, that turns the option off -- just like if
--enable-zip-archive was called with the value 'no'. If libzip is

Consider symbol versions' public-ness during comparison
* src/abg-ir.cc (elf_symbol::operator==): Rather than comparing
bindings, compare public-ness here. That is, if two symbol
versions' differ because one is GLOBAL and the other one is WEAK,
they should still be considered equal, from an ABI standpoint.
2014-08-27 Dodji Seketeli <dodji@redhat.com>
Lookup proper names of symbol during determination of deleted/added decls
* src/abg-comparison.cc

Look at first parm type and artificial-ness to detect static-ness
* src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir): To
tell if a member function is static, look if the first parm is a
pointer to the type of the enclosing class, and if it's

emitted by GCC 4_4.

options::show_linkage_names to true and
options::show_harmful_changes to false.

* src/abg-dwarf-reader.cc (get_scope_for_die): If the DIE has a
DW_AT_specification or DW_AT_abstract_origin attribute, get the
scope of the referred-to DIE.
(build_ir_node_from_die): For a variable DIE that has a

built variable IR node to its scope because it is already in a
scope. It's in a scope because that built variable is for the DIE
that is referred-to by the DW_AT_{specification,abstract_origin}
attribute. Likewise for member functions. Also, now,
get_scope_for_die can return a class for a function DIE because
get_scope_for_die now returns the *logical* scope of the DIE; that
is, it follows DW_AT_{specification,abstract_origin} attributes.
* tests/data/test-read-dwarf/test1.abi: Adjust.

Add clone in the scope of the cloned decl they logically belong to

Drop symbols not global in a symtab from corpus symtab
* src/abg-corpus.cc (corpus_priv::build_symbol_table): If a
function or variable symbol is not public (global or weak) and
present in an elf symbol table, drop it from the corpus symbol
table. As a result functions are variables (not present in the
elf symbol tables) that we were previously taking in account are
not dropped on the floor, leading to much less noise.

2014-04-17 Dodji Seketeli <dodji@redhat.com>
Simplify SIZE_OR_OFFSET_CHANGE_CATEGORY categorizing
* src/abg-comp-filter.cc (harmful_filter::visit): Now that
type_size_changed is correctly geared to not be fulled by
decl-only classes, there is no need for its caller to handle that
case. And data_member_offset_changed ain't affected by decl-only
classes anyway. So the code is now much simpler.

Don't blindly drop DIEs defined in the scope of a function
* src/abg-dwarf-reader.cc (get_scope_for_die): Do not drop a DIE
on the floor just because it is in the scope of a function. We
were dropping a function parameter because its type is a typedef
defined right before the parameter, in the scope of the function.
Urgh. So with this change, that function parameter is not dropped
anymore. I have seen that happening in a DWARF generated by GCC
4.7.1 on libstdc++.so. Hard to come up with a regression test
case for this one.

Really detect static-ness of data members. Oops.
* src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir): Let's
consider that a data member being not laid out (i.e, not having a
data_member_location) is is a static data member. Otherwise, we
were not detecting static data members at all. Well we were only
inferring their presence from seeing the static variable
definition later on. That means we were missing most of the
static variables. Woops.
* src/abg-comparison.cc
(corpus_diff::priv::ensure_lookup_tables_populated): Now that we
are really seeing static data members, let's be prepare to the
fact that we can the same static data member being declared

A virt mem fn deleted and added to the same offset is not harmful
* src/abg-comp-filter.cc (has_virtual_mem_fn_change): A virtual

offset is not considered as being a virtual member function change
suitable for VIRTUAL_MEMBER_CHANGE_CATEGORY. Likewise for a
function sub-type change not involving a change in the vtable
offset.

(type_size_changed, data_member_added_or_removed)
(has_virtual_mem_fn_change, has_non_virtual_mem_fn_change): Bail
out if one of the types involved is a decl-only class.

Work around "mangled name vanishing from one version of mem fn decl" bug
* src/abg-comparison.cc
(class_diff::ensure_lookup_tables_populated): If the first version

Provide a robust way of getting the size of a qualified type
* include/abg-ir.h (qualified_type_def::get_size_in_bits): Declare
new member function ...
* src/abg-ir.cc (qualified_type_def::get_size_in_bits): ... and
define it. Keep in mind that some times the size of the
underlying type can change between the moment the qualified type
is created and the end of its life time. That is because a
subsequent DIE (from DWARF) can alter the size of the underlying
type. This overload allows the user to always query the size of
the underlying type and keep the size of the qualified type in
sync with it.
2014-04-16 Dodji Seketeli <dodji@redhat.com>
Add an assert to the pointer diff reporting code
* src/abg-comparison.cc (pointer_diff::report): If the pointer

Little style adjustment in diff node categorization code
* src/abg-comp-filter.cc (harmful_filter::visit): Factorize the

adding or removal and for data member type size change.
2014-04-15 Dodji Seketeli <dodji@redhat.com>
If a diff node is in NO_CHANGE_CATEGORY do not report it anymore
* src/abg-comparison.cc (diff::is_filtered_out): Now that we seem
to be flagging every changes to a class into a category, we do not
need to dive into reporting a diff not that is categorized as
NO_CHANGE_CATEGORY anymore. So let's have the implementation that
one would expect for this function.
2014-04-15 Dodji Seketeli <dodji@redhat.com>

Fix the static data member recognition hack
* src/abg-dwarf-reader.cc (build_translation_unit_and_add_to_ir):
When trying to recognize the global var_decl as being definition
variables for static data members, lookup the declaration for the
data member in the relevant class. If found, then just flag the
var_decl for the data member as being static; no need to add a
var_decl as data member in that case, that would duplicate the
data member.

Make type_base::get_{size,alignment}_in_bits virtual
* include/abg-ir.h (type_base::get_{size,alignment}_in_bits): Make
this virtual.
(typedef_decl::get_{size,alignment}_in_bits): Add new member
functions. Get the size,alignment from the underlying type and
update the current size/alignment if they differ. Keep in mind
that the size of an underlying class_decl can change over its
lifetime, given how the dwarf reader reads the type information,
i.e, there can be a DIE for a class type with no size information
that will lead to the creation of a class_decl with size zero.
Later during the DWARF reading process, another DIE will
supplement the type information, adding size information to that
class_decl. In between, a typedef_decl might have been created
with the first version of the class_decl that has a zero size. I
guess this should be extended to the other type constructs that
have an underlying type (qualified types, references and pointers).

Better support of static member variables
* include/abg-fwd.h (fqn_to_components)
(lookup_type_in_translation_unit, demangle_cplus_mangled_name):
Declare new public entry points
* src/abg-comparison.cc (corpus_diff::report): Report stuff about
global variables using their mangled name, and demangle them. If
there is no mangled name for the variable, then use its pretty
representation.
(compute_diff): For the corpus overload, compare global variables
using their mangled name, if its available; otherwise, fall back
to using their pretty representation.
* src/abg-corpus.cc (var_comp::operator()(const var_decl*,
const_var_decl*)): Compare variables using their mangled name in
priority. If it's not available then use their pretty
representation.
* src/abg-dwarf-reader.cc
(read_context::var_decls_to_re_add_to_tree): New accessor.
(build_translation_unit_and_add_to_ir): If there is what appears
to be a definition of a static member variable variable -- this is
in case this definition lacks the DW_AT_specification attribute
that links it to the DW_TAG_member or DW_TAG_variable DIE that is
a child of the right class/structure DIE -- that is not at the
right place in the DIE tree, remove it from the its current place
in the tree and try to hang it off of the right DIE. To do this,
de-mangle its mangled name, look at what is supposed to be the
parent class name, look it up in the translation unit IR, and if
found, stick the variable IR node in there, as a static member
variable. If not found, then bad luck.
(build_class_type_and_add_to_ir): Do not try to see if a member
variable is static here as the way I was doing it was unreliable.
Build the data member node directly w/o going through building a
variable node first. Register the data member in the die offset
-> IR node map.
(build_ir_node_from_die): When seeing DW_TAG_variable, look for a
DW_AT_specification attribute. If there is one, then it points to
a the DIE of a data member and means that data member is static.
Flag the IR node of that data member as static thus. Update the
die offset -> IR node map. If there is no DW_AT_specification
attribute or if it doesn't point to a data member DIE, schedule
this variable tag for a stage when after the whole IR is built for
the translation unit, the variable's mangled named is inspected,
its hypothetical parent struct/class is looked up and the variable
IR node is put into the node of the right struct/class IR node.
* src/abg-ir.cc (enum lookup_entity_kind): New.

declaration-only class, representing the declaration for the class
that is being constructed. This breaks circular dependencies
induced by decls/types that refer to the class being built, before
the class is fully built and has a (logical) type ID. Once the
class is created, make it refer to the class declaration that was
previously handed for the requests to the class DIE. Now requests
to the class DIE will just yield the newly built class. Add
support for member functions and member types.

class_decl::member_function, class_decl::member_function_template,
class_decl::member_class_template}::traverse): Add a virtual

* src/abg-dwarf-reader.cc (die_decl_map_type): Change this map
type so that the value is now a DIE offset, rather than a DIE.
This is because many times the lifetime of DIEs is shorter than
the one of the reader_context. Also, the die offset uniquely
designates a physical DIE even if several different instances of
logical DIE might point to it.
(struct die_hash): Remove this as it's useless now that we store
DIE offsets in the map.
(build_translation_unit): Call build_ir_node_from_die w/o setting
the called_from_public_decl flag. Prune the types that are not
used by any public decls.

called_from_public_decl flag set to true to flag the types
referenced by this variable as being used.
(build_function_decl): Take a called_from_public_decl flag as
well, as this function can now call build_function_decl itself to
build a function decl out of the value of the DW_AT_specification
attribute, for DIEs representing function definitions. Also, flag
the types referenced by public functions are being used.
* src/abg-ir.cc (translation_unit::priv::used_types_): New map for

* src/abg-dwarf-reader.cc (build_translation_unit): Remove the
"recurse" parameter. Adjust the call to build_ir_node_from_die to
read just public decls that are at namespace scope. Anything else
should be dropped unless it's needed to emitting the public
namespace-level decls.
(build_namespace_decl_and_add_to_ir)
(canonicalize_and_insert_type_into_ir): Define new static
functions.
(build_corpus): Adjust ad build_translation_unit doesn't have the
"recurse" parameter anymore.
(canonicalize_and_add_type_to_ir): Make this static. Fix
comments.
(build_ir_node_from_die): Take a new "only_public_decl"
parameter. For DW_TAG_base_type case, use the new
canonicalize_and_insert_type_into_ir to insert the type at the
right place in the global scope making sure it is seen before the
current scope. For pointer, references and qualified types, use
canonicalize_and_insert_type_into_ir to add the type at the same
scope as its underlying type. Handle DW_TAG_{namespace,module}
using the new build_namespace_decl_and_add_to_ir function. Add
some vertical spaces and some assertions.
* src/abg-ir.cc (scope_decl::add_member_decl): Use scope_decl_sptr
typedef.
(scope_decl::{insert_member_decl,find_iterator_for_member}):
Define new methods.
(insert_decl_into_scope, get_top_most_scope_under): Define new
functions.

typedef.
(global_scope_sptr, namespace_decl_sptr): New convenience typedef.
(class global_scope): Remove useless white space.

canonicalize_and_add_type_to_ir now takes smart pointers on
scopes. Support the DW_TAG_typedef case by calling the new
build_typedef_type.
2013-12-11 Dodji Seketeli <dodji@redhat.com>

Declare new overloads that act on a naked pointer to decl_base.
* src/abg-dwarf-reader.cc (build_pointer_type_def): Define new
static function.
(canonicalize_and_add_type_to_ir): Take a naked pointer to
scope_decl rather than a smart pointer.
(build_ir_node_from_die): For DW_TAG_base_type, adjust. Support
DW_TAG_pointer_type case. For DW_TAG_{const,volatile}_type case,
make sure the qualified type is in the same scope as its
underlying type.
* src/abg-ir.cc (get_global_scope, get_translation_unit): Define
new overloads that acts on a naked decl_base.
2013-12-11 Dodji Seketeli <dodji@redhat.com>

(build_type_decl): Really take a context parameter. Use the new
die_loc_and_name() here.
(build_var_decl): Skip non-public vars.
(build_corpus): Use dwarf_nextcu instead of dwfl_nextcu, so that
we can get the address_size used in the current CU. Note that for
this we are getting the Dwarf* pointer from the context thanks to
the new read_context::dwarf() getter. Adjust the call to
build_translation_unit to pass it the new address_size.
(build_ir_node_from_die): Shorten lines a little bit. Call the
new build_function_decl to support reading DW_TAG_subprogram DIEs.
(read_corpus_from_elf): Adjust to create the read context earlier
and use its read_context::load_debug_info method to load the debug
info.

the --noout option as well.
(main): Support Read the abi instr from stdin; in that case, what
was read is just serialized back to stdout, unless --noout was
supplied.
2013-12-11 Dodji Seketeli <dodji@redhat.com>

Make it support introducing changed members as well as
deletions/insertions.

report_mem_header change. Use the new represent() overload to
report about changed data members. Adjust logic now that

as representing base classes and member types changes is
concerned.

(class_diff::{clear_lookup_tables, lookup_tables_empty,
ensure_lookup_tables_populated}): Define new methods.
(class_diff::report): Detect and report when a base class or a
member type has changed, as opposed to just saying that it has
been removed and inserted. Fix the rest of the function to avoid
emitting useless vertical space and avoid saying that the class
has "zero" insertion/deletion of a given kind of member.
(scope_diff::report): avoid saying that the scope has "zero"
insertion/deletion of a given kind of member. Avoid useless
vertical spaces.
(type_decl_diff::report): Avoid useless vertical spaces.

2013-11-19 Dodji Seketeli <dodji@redhat.com>
Avoid missing member types while reading bi files
* include/abg-fwd.h (get_type_declaration): Declare function.
* include/abg-ir.h (class decl_base): Add class_decl as a friend.
This to be able to call decl_base::set_scope from class_decl.
(scope_decl::add_member_decl): Make this virtual protected, so
that it can be called (virtually) from e.g, class_decl.
(type_decl_sptr, typedef_decl_sptr): New convenience typedefs.
(class_decl::add_member_decl): New virtual overload for
scope_decl::add_member_decl.

(get_type_declaration): Define new function.
(class_decl::add_member_decl): New method.
(class_decl::add_member_type): Avoid silently added a new member
type when that member type has already been (perhaps
inadvertently) added to a scope already. Rather, put a strict
assert in place there. Also add a new overload that constructs
the member type out of a classic type and adds it to the class.
(class_decl::{add_data_member, add_member_function}): Likewise.
(class_decl::{add_member_function_template,
add_member_class_template}): Avoid silently added a new member
template when that template has already been (perhaps
inadvertently) added to a scope already. Rather, put a strict
assert in place there.
* src/abg-reader.cc (push_decl_to_current_scope): Take a an extra
flag saying if the current decl should be added to the current
scope as well (in addition to being pushed onto the stack of
scopes maintained in the reader context).
(push_and_key_type_decl): Likewise, take that extra flag and pass
it to push_decl_to_current_scope.
(build_function_decl, build_var_decl, build_type_decl)
(build_qualified_type_decl, build_pointer_type_def)
(build_reference_type_def, build_enum_type_decl, build_typedef_decl)
(build_function_tdecl, build_class_tdecl): Likewise.
(build_class_decl): Likewise. When building member data, types,
and functions, make sure /not/ to add the data, type of function to
the current scope before adding it to the class_decl. This was
making the member not being added to the class because it already
had a scope.
(build_type_tparameter, build_type_composition)
(build_non_type_tparameter, build_template_tparameter)
(build_type): Adjust to add the template parm to the current scope
explicitly, like previously.
(handle_type_decl): Use build_type_decl function. Add the
type_decl to the current scope, like previously.
(handle_namespace_decl, handle_qualified_type_decl)

definition.
(function_decl::get_pretty_representation): Represent
destructors and const member functions.
* src/abg-writer.cc (write_cdtor_const_static): Take a new bool
parm for constness and serialize it.
(write_class_decl): Serialize member functions & function template
const-ness.
* src/abg-reader.cc (read_cdtor_const): Read the "const" xml
attribute, rather than "is_const".
2013-10-24 Dodji Seketeli <dodji@redhat.com>
Fix num insertions reporting in member functions
* src/abg-comparison.cc (class_diff::report): Fix num insertions
reporting.
2013-10-24 Dodji Seketeli <dodji@redhat.com>
Serialize vtable offset for virtual functions
* include/abg-ir.h
(class_decl::member_function::get_vtable_offset): Renamed
class_decl::member_function::get_vtable_offset_in_bits into this.
The offset is an index into a table; it's not a value in bits.
* src/abg-hash.cc (class_decl::member_function::hash): Update wrt
function name change above.
* src/abg-ir.cc (class_decl::member_function::operator==):
Likewise.
* src/abg-reader.cc (build_class_decl): Rename the attribute
vtable-offset-in-bits into vtable-offset.
* src/abg-writer.cc (write_voffset): New function.
(write_class_decl): Use the new write_voffset. Cleanup.

Do not report added/removed type_decls
* src/abg-comparison.cc (scope_diff::report): Do not report
added/removed type_decls.
2013-10-24 Dodji Seketeli <dodji@redhat.com>
Fix string representation for variables and methods
* src/abg-ir.cc (var_decl::get_pretty_representation): Don't use
the pretty representation for the type of the variable; just use
its qualified name.
(method_type::set_class_type): I wonder what I was thinking when
setting the first parameter's type to being the type of the
class. Remove this.
(function_decl::get_pretty_representation): Use the "method "
prefix for methods. Avoid printing the first parameter of
methods. Use the qualified name of the parameter type, rather
than its pretty representation.
* src/abg-writer.cc (write_class_decl): Do not skip the first
function parameter when serializing the method.
2013-10-24 Dodji Seketeli <dodji@redhat.com>

2013-10-24 Dodji Seketeli <dodji@redhat.com>
Fix erratic reporting of changed types & decls in scopes
* src/abg-comparison.cc
(scope_diff::ensure_lookup_tables_populated): A changed type/decl
is not only one that has been both deleted and inserted (as is a
type/decl with a given name N has been deleted and a type/decl
with that same name N has been inserted), but we must also ensure
that both inserted and deleted type/decl are not the same.
Otherwise, it might has been a type/decl that has been shuffled
around.
2013-10-24 Dodji Seketeli <dodji@redhat.com>
Fix some class & scope diff reports formatting glitchs
* src/abg-comparison.cc (class_diff::report): Quote data members.

2013-10-24 Dodji Seketeli <dodji@redhat.com>
Re-write middle snakes management in core diff algorithms
* include/abg-diff-utils.h (point::set): New overload..
(point::{add, operator<, operator>, operator<=, operator>=}): New
methods.
(point::operator!=): Constify.
(point::operator==): Constify. Cleanup.
(point::operator=): Keep emptiness.
(class snake): New class definition
(d_path_vec::{over_bounds, offset}): New methods.
(d_path_vec::check_index_against_bound): Don't take a bound
parameter anymore. Use the new over_bound method above. Fix up
error reporting.
(d_path_vec::d_path_vec): Fix d_path_vec size allocation.
(d_path_vec::operator[]): Use the d_path_vec::at method to check
all accesses against the bounds. This is slower, but at least we
can expect to have something that is more robust. We can remove
the bound checking later when we are sure the code has been tested
enough. Also use the new offset() method.
(d_path_vec::at): Take long long.
(ends_of_furthest_d_paths_overlap): Constify input parameters.
(end_of_fr_d_path_in_k, end_of_frr_d_path_in_k_plus_delta): Take
an instance of the new snake in parameter, rather than a bare end
point that wasn't carrying enough information about the snake.
Record the snake which consists of up to four points: a begin
point, an intermediate point, a diagonal start point and an end
point. Return that snake upon successful completion.
(compute_middle_snake): Take an instance of snake, rather than the
two points that were supposed to represent a snake and with which
we were loosing information before. Revisit/simplify the logic of
this function; this literally goes forward or in reverse, gets the
resulting snake returned by the end_of_fr_d_path_in_k and
end_of_frr_d_path_in_k_plus_delta functions, detect if these snakes
overlap and just return the current snake. Much simpler. The
caller now gets a snake, which has much more information than the
previous snake approximation made of just two points. Bonus
point, this follows almost to the word, what the paper says.
(maybe_record_match_point, find_snake_start_point): Remove these
as there are not used by compute_middle_snake anymore.
(print_snake, ses_len): Update these to take/handle a snake.
(snake_end_points): New declaration.
(compute_diff): When we are getting an empty first sequence, this
means that we are inserting the second sequence *before* the
beginning of the first sequence; keep this information by setting
the insertion point index to -1, rather than zero. Update this to
get/handle snakes, rather than free points vaguely representing
snakes. Now that compute_middle_snake returns real snakes, handle
the information we are getting. Basically for edit scripts of
length equal to 1, as the snake carries all the necessary
information about the non-diagonal edge (as well as the diagonal
edges), we (can) now precisely update the current edit script (as
well as the longest common sub-sequence). For edit scripts of
length greater than 1, better at which points to divide the
problem and consequently, at which points to conquer it back --
better following The Paper to the letter.
(display_edit_script): Update this for the use of instances of
snake.
* src/abg-diff-utils.cc (ends_of_furthest_d_paths_overlap): Update
for constification of inputs.
(snake_end_points): Define new function.
(compute_middle_snake): Adapt for the taking an instance of snake.
* tests/test-diff2.cc (main): Update for using instances of snake.
* tests/test-core-diff.cc: Add new tests.
* tests/data/test-core-diff/report0.txt: Update for output
adaptation.

forget to compare the decl_base part of the type too.

* include/abg-ir.h (*lots of descendants of decl_base, type_decl)
(template_decl, class_decl::member_base): Replace the previous classical
*::operator==(*&) with an overload of decl_base::operator==(const
decl_base&), type_base::operator==(const type_base),
template_decl::operator==(const template_decl&) or

Fix middle snake determination & ses len computation for d == 1
* include/abg-diff-utils.h (compute_middle_snake): After the
overlap determination happened, finding the middle snake can
require keep on building the current path until the "end". The
end meaning reaching the max of D. And that max is (M + N)/2 + 1.
In the extreme cases were middle snake was on the very last step
(M + N) + 1, we were not finding the middle snake. Fix this.
(compute_diff): When d == 1 and the first edge on the edit graph
is a non-diagonal edge and when a_base != a_begin, we were failing
to properly initialize x,y to find that non-diagonal edge. Also
we were failing to correctly compute the size of the sequence.
Fix these.

operators.
(end_of_fr_d_path_in_k, end_of_frr_d_path_in_k_plus_delta): Allow

(find_snake_start_point): New functions.
(find_last_snake_in_path): Remove this. It's not used anymore.

enough to hold paths for M+N differences. Normally M+N/2 should
be enough, but we were getting weird out of bound errors. Let's
handle it this way for now. Do not require that we check for
overlap only when we are on a diagonal edge. Once we detected an
overlap, use the new find_last_snake_in_path to find the
boundaries of the snake.
(ses_len): Delta can be negative.
(display_edit): Small minor English nit.

$(top_builddir)/config.h file.
2013-08-27 Dodji Seketeli <dodji@redhat.com>
Pass absolute paths to the compiler during the build
* src/Makefile.am: Pass absolute file paths to the compiler during
the build. This helps in e.g in emacs' compilation mode, when the
output shows an error reported by GCC's diagnostics, setting point
to the error line and hitting 'enter' transports the user to the
file location where the error happened; as the file path is nows
absolute, emacs can always find it. Otherwise, finding it depends
on $PWD and whatnot.
* tests/Makefile.am: Likewise.
2013-08-27 Dodji Seketeli <dodji@redhat.com>
Misc cleanups in abg-fwd.h
* include/abg-fwd.h: Move location, location_manager and
translation_unit in the ir section. Remove stuff that was
commented out anyway.
2013-08-27 Dodji Seketeli <dodji@redhat.com>
Move location, location_manager & translation_unit back into abg-ir.h
* include/abg-corpus.h: Move location location_manager,
translation_unit from here ...
* include/abg-ir.h: ... to here. The reason being that these are
really constructs of the Internal Representation of the ABI/API of
a translation unit. What is left in abg-corpus is really
exclusively related to an ABI Corpus, which I see more as a
"packaging" construct that abstracts the bundling of several
translation units together. Also, I fixed some comments about the
location/location_manger types; now a location is made specific to
a translation unit; to an abi corpus. A location of a given
translation unit has to be decoded by the location manager of that
same translation unit.
2013-08-22 Dodji Seketeli <dodji@redhat.com>

Fix typo in CONTRIBUTING file
* CONTRIBUTING: Fix typo, courtesy of Mark Wielaard.
2013-08-19 Dodji Seketeli <dodji@redhat.com>
Remove autotools-generated files
* Makefile.in: Remove this autotools-generated file. I know that
people in the GCC-realm like storing these autotools-generated
files into the source control system, but I believe in this day
and age, this is annoying (to say the least) for the project
developers for no good reason. Requiring (the ubiquitous)
autoconf for building from source is no big deal today, and typing
"autoreconf" is not hard to do, really. And it saves the
developers for having to update a bunch of boilerplate
automatically generated files into the source control system; this
is really unnecessary noise and it is a commonly accepted good
practice to avoid doing it these days. To help people who do not
know how to handle this, there is a COMPILING file in the source
tree that explains how to build the project from sources.
