Dodji Seketeli	610d87c29b	Represent undefined corpus interfaces to analyze app compatibility ... In the text below, the term interface means the "declaration of either a function or a global variable". To analyze the compatibility between an application and a dependent library, one has essentially to analyze the interfaces of the application that have undefined symbols (aka undefined interfaces from the application) and see how they relate to the same interfaces coming from the library but with symbols that are defined and exported from the library (aka defined/exported interfaces from the library). An interface that is undefined in the application and defined in the library is an interface that the application consumes from the library. In other words an undefined interface from an application is an interface that the application expects and an interface that is exported by a library is an interface that the library provides. If comparing the expected interface against the provided interface yields a meaningful difference, then that might mean there is an incompatibility between the application and the library on that interface. This patch uses this scheme to re-implement the weak mode of ABI compatibility between an application and a library. The patch adds the concept of undefined functions and variables to the ABI corpus. Then it teaches the DWARF reader how to construct the IR for these undefined interfaces. Then it revisits the weak mode of operation of abicompat to make it compare the interfaces expected from the application against the corresponding interfaces provided by library. The patch also teaches the weak mode abicompat how to detect incompatibilities between the interfaces that plugin expects and the interfaces provided by the application. This patch makes the CTF front-end construct undefined interfaces. A subsequent patch is needed to construct undefined interfaces from the BTF front-end however. * include/abg-corpus.h (corpus::{lookup_variable, get_undefined_functions, get_undefined_variables}): Declare new member functions.

Dodji Seketeli	19d4131964	Improve type naming ... There are a number of glitches when pretty-printing type names. This is particularly true for derived types like pointer to functions, array of pointer to functions and the likes. For instance, we can see in tests/data/test-abidiff-exit/PR30048-test-2-report-1.txt that a function N that takes no parameter and returns a pointer to an array of 7 int is pretty-printed as: int[7]* N() That obviously doesn't respect the type naming rules of C or C++. With this patch, function N is declared as: int(*N(void))[7] To learn more about the impact of the patch on how types are pretty-printed, you can look at the parts of the patch that are adjustments to the expected output of the regression tests. For instance, here is how the expected output of type pretty-printing in tests/data/test-abidiff-exit/PR30048-test-2 is modified by this patch: diff --git a/tests/data/test-abidiff-exit/PR30048-test-2-report-1.txt b/tests/data/test-abidiff-exit/PR30048-test-2-report-1.txt index 2650b5a0..7bbbc2e2 100644 --- a/tests/data/test-abidiff-exit/PR30048-test-2-report-1.txt +++ b/tests/data/test-abidiff-exit/PR30048-test-2-report-1.txt @@ -3,22 +3,22 @@ Variables changes summary: 0 Removed, 0 Changed, 0 Added variable 7 functions with some indirect sub-type change: - [C] 'function int[7]* N()' at PR30048-test-2-v0.cc:62:1 has some indirect sub-type changes: + [C] 'function int(*N(void))[7]' at PR30048-test-2-v0.cc:62:1 has some indirect sub-type changes: return type changed: - entity changed from 'int[7]*' to 'int' + entity changed from 'int(*)[7]' to 'int' type size changed from 64 to 32 (in bits) - [C] 'function int* O()' at PR30048-test-2-v0.cc:64:1 has some indirect sub-type changes: + [C] 'function int* O(void)' at PR30048-test-2-v0.cc:64:1 has some indirect sub-type changes: return type changed: entity changed from 'int*' to 'int' type size changed from 64 to 32 (in bits) - [C] 'function int ()* P()' at PR30048-test-2-v0.cc:67:1 has some indirect sub-type changes: + [C] 'function int (*P(void))(void)' at PR30048-test-2-v0.cc:67:1 has some indirect sub-type changes: return type changed: - entity changed from 'int ()*' to 'int' + entity changed from 'int (*)(void)' to 'int' type size changed from 64 to 32 (in bits) Note that the change to the CTF test tests/data/test-read-ctf/test9.o.abi is triggered by a change in the sorting of types because types are sorted alphabetically.

Matthias Maennich	ff4b4a56b4	symtab/dwarf-reader: allow hinting of main symbols for aliases ... In case of aliased symbols, the "main symbol" cannot be deduced from the symtab as this solely contains a name->addr mapping and aliases are represented by multiple names resolving to the same address. Therefore the main symbol can only be picked rather randomly and unpredictable. Unlike DWARF, which contains a single symbol entry for only the main symbol. Hence we can (late) detect the main symbol. Exploiting that property allows to correct the addr->symbol lookup in the symtab to return the correct main symbol and it also allows to correct the aliased symbols to maintain the correct main symbol. This patch adds the `update_main_symbol` functionality to `elf_symbol` to update the main symbol by name (ELF symbols need unique names) and adds `update_main_symbol` to `symtab` that makes use of said new method. When we discover a main symbol during DWARF reading, we instruct the symtab to update the mapping. This creates consistent representations across different builds of the same binary with the same ABI by pinning down the main symbol to the defined one. Knowing the main symbol also helps to keep the correct dwarf information in the representation in the presence of symbol suppressions. A later patch will address that. Some test cases in tests/data need adjustment and they have all been verified to be valid changes. - main symbol changed for various elf symbols - test-annotate/test15-pr18892.so.abi - test-annotate/test19-pr19023-libtcmalloc_and_profiler.so.abi - test-annotate/test3.so.abi - test-read-dwarf/test15-pr18892.so.abi - test-read-dwarf/test19-pr19023-libtcmalloc_and_profiler.so.abi - test-read-dwarf/test3.so.abi - test-read-dwarf/test3.so.hash.abi - due to main symbol changes, the symbol diff needs to be corrected - test-diff-dwarf/test12-report.txt - test-diff-pkg/tbb-4.1-9.20130314.fc22.x86_64--tbb-4.3-3.20141204.fc23.x86_64-report-0.txt - test-diff-pkg/tbb-4.1-9.20130314.fc22.x86_64--tbb-4.3-3.20141204.fc23.x86_64-report-1.txt - the test scenario needed adjustments as the main symbol changed - test-diff-suppr/test23-alias-filter-4.suppr - test-diff-suppr/test23-alias-filter-report-0.txt - test-diff-suppr/test23-alias-filter-report-2.txt As usual, the complete changelog follows. * include/abg-ir.h (elf_symbol::update_main_symbol): New method. * include/abg-symtab-reader.h (symtab::update_main_symbol): New method. * src/abg-dwarf-reader.cc (build_var_decl): Hint symtab about main symbol discovered in DWARF.

Dodji Seketeli	2f92777dc8	Consider the implicit 'this' parameter when comparing methods ... Since 2013 the implicit 'this' parameter has been excluded from the function parameters taken into account while comparing class member functions. This was an early measure to avoid infinite recursion that would then occur when comparing classes (and thus their member functions that are referenced in their vtable). But since then, we've built descent infrastructure to prevent this kind of recursion in a more generic manner. This patch thus removes that restriction and should therefore lift the concerns expressed in the bug https://sourceware.org/bugzilla/show_bug.cgi?id=26672. Namely, changes to (data members of) a class should now be detected when comparing member functions of that class. With this change, the reference output of several comparison regression tests changed because, obviously, some impacted member functions are now reported along with detecting changes in data membrers of classes. The patch thus adjusts those reference ouputs. The patch also adjust the behaviour of the predicate: "accessed_through = pointer|reference|reference-or-pointer" The idea is to make the predicate work on qualified version of a type. * include/abg-ir.h (function_type::get_first_parm): Declare new accessor. * src/abg-ir.cc (function_type::get_first_parm): Define new accessor. (equals): In the overload for function_type, always take the implicit "this" parameter into account in parameter comparisons. (function_type::get_first_non_implicit_parm): Adjust comment. * src/abg-comp-filter.cc (function_name_changed_but_not_symbol): Avoid potential NULL pointer dereferencing. * src/abg-comparison.cc (function_type_diff::ensure_lookup_tables_populated): Always take the changes to the implicit 'this' parameter into account in the function type diff. (compute_diff): In the overload for function_type, Always compare the implicit 'this' parameter when comparing function parameters. * src/abg-default-reporter.cc (default_reporter::report): Refer to "implicit parameter" when reporting changes on parameters artificially generated by the compiler. * src/abg-suppression.cc (type_suppression::suppresses_diff): Make the 'access_through' predicate work on a qualified version of type 'S', even if it was meant to work on type 'S'. This allows it to work on 'const S', especially when S is accessed through 'pointer to const S', which happens when we consider the implicit 'this' parameter of a const member function. * tests/data/test-abicompat/test5-fn-changed-report-0.txt: Adjust. * tests/data/test-abicompat/test5-fn-changed-report-1.txt: Likewise. * tests/data/test-abidiff-exit/test1-voffset-change-report0.txt: Likewise. * tests/data/test-abidiff/test-PR18791-report0.txt: Likewise. * tests/data/test-abidiff/test-struct1-report.txt: Likewise. * tests/data/test-diff-dwarf-abixml/test0-pr19026-libvtkIOSQL-6.1.so.1-report-0.txt: Likewise. * tests/data/test-diff-dwarf/test0-report.txt: Likewise. * tests/data/test-diff-dwarf/test28-vtable-changes-report-0.txt: Likewise. * tests/data/test-diff-dwarf/test29-vtable-changes-report-0.txt: Likewise. * tests/data/test-diff-dwarf/test30-vtable-changes-report-0.txt: Likewise. * tests/data/test-diff-dwarf/test31-vtable-changes-report-0.txt: Likewise. * tests/data/test-diff-dwarf/test36-ppc64-aliases-report-0.txt: Likewise. * tests/data/test-diff-dwarf/test41-PR20476-hidden-report-0.txt: Likewise. * tests/data/test-diff-dwarf/test42-PR21296-clanggcc-report0.txt: Likewise. * tests/data/test-diff-dwarf/test5-report.txt: Likewise. * tests/data/test-diff-dwarf/test8-report.txt: Likewise. * tests/data/test-diff-filter/test0-report.txt: Likewise. * tests/data/test-diff-filter/test01-report.txt: Likewise. * tests/data/test-diff-filter/test10-report.txt: Likewise. * tests/data/test-diff-filter/test13-report.txt: Likewise. * tests/data/test-diff-filter/test2-report.txt: Likewise. * tests/data/test-diff-filter/test28-redundant-and-filtered-children-nodes-report-0.txt: Likewise. * tests/data/test-diff-filter/test28-redundant-and-filtered-children-nodes-report-1.txt: Likewise. * tests/data/test-diff-filter/test30-pr18904-rvalueref-report0.txt: Likewise. * tests/data/test-diff-filter/test30-pr18904-rvalueref-report1.txt: Likewise. * tests/data/test-diff-filter/test30-pr18904-rvalueref-report2.txt: Likewise. * tests/data/test-diff-filter/test31-pr18535-libstdc++-report-0.txt: Likewise. * tests/data/test-diff-filter/test31-pr18535-libstdc++-report-1.txt: Likewise. * tests/data/test-diff-filter/test35-pr18754-no-added-syms-report-0.txt: Likewise. * tests/data/test-diff-filter/test35-pr18754-no-added-syms-report-1.txt: Likewise. * tests/data/test-diff-filter/test4-report.txt: Likewise. * tests/data/test-diff-filter/test41-report-0.txt: Likewise. * tests/data/test-diff-filter/test9-report.txt: Likewise. * tests/data/test-diff-pkg/libsigc++-2.0-0c2a_2.4.0-1_amd64--libsigc++-2.0-0v5_2.4.1-1ubuntu2_amd64-report-0.txt: Likewise. * tests/data/test-diff-pkg/tbb-4.1-9.20130314.fc22.x86_64--tbb-4.3-3.20141204.fc23.x86_64-report-0.txt: Likewise. * tests/data/test-diff-pkg/tbb-4.1-9.20130314.fc22.x86_64--tbb-4.3-3.20141204.fc23.x86_64-report-1.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-0.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-1.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-10.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-11.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-12.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-13.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-14.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-15.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-16.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-2.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-3.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-4.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-5.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-6.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-7.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-8.txt: Likewise. * tests/data/test-diff-suppr/test24-soname-report-9.txt: Likewise. * tests/data/test-diff-suppr/test31-report-1.txt: Likewise. * tests/data/test-diff-suppr/test33-report-0.txt: Likewise.

Giuliano Procida	a5a67c2ffd	abidiff: Clean up new lines between sections. ... Some blank lines were unintentionally removed with a recent patch. The new line to remove should have been the one after all changed functions not the one after each one.

This patch removes the blank line emitted after all changed functions, variables and unreachable types, and adds back the missing blank lines between changed functions. * src/abg-default-reporter.cc (report): In the corpus_diff override, add back the extra blank line per changed function but remove the extra one after all changed changed functions and variables; comment these. * src/abg-leaf-reporter.cc (report): In the corpus_diff override, add back the extra blank line per changed function but remove the extra one after all changed changed functions and variables; comment these. * src/abg-reporter-priv.cc (maybe_report_unreachable_type_changes): Remove extra blank line emitted after all unreachable type changes; comment this. * tests/data/test*report*.txt: Remove/add blank lines.

These tags were previously only emitted by the default reporter if the there were more than 100 (hard-coded constant) items in a a list. The leaf reporter emitted them unconditionally. This change simplifies the code, makes output more consistent and makes it easier to interpret diffs of diff output. Additionally, in the reporting of changed unreachable types, the indentation and quoting for the deleted and added cases was missing. This patch corrects these issues. Finally, when doing package differences, there were no tags for deleted/added binaries. This patch adds them. * src/abg-default-reporter.cc (report): In the corpus_diff override, remove calculations of number of changes (total) and comparisons against arbitrary threshold (large_num); emit [A], [D], [C] tags unconditionally. * src/abg-reporter-priv.cc (maybe_report_unreachable_type_changes): Remove comparisons of number of changes against arbitrary threshold (large_num); emit [A], [D], [C] tags unconditionally; fix quoting of deleted unreachable types; fix indentation of changed unreachable types. * tools/abipkgdiff.cc (compare_prepared_userspace_packages): Emit [D] and [A] tags for removed and added binaries. * tests/data/test-*/*report*.txt: In 109 report files, add tags [A], [D], [C] tags and correct some indentation and quoting.

Giuliano Procida	0fd7565d06	Eliminate some unnecessary blank lines in diff output. ... v2: More code simplification. Tests unchanged. There is distributed responsibility for horizontal and vertical whitespace in the reporting code with indent and new line control information being manipulated by and passed in and out of functions. Occasionally, this information is ignored or incorrect and the code tends to err on the side of more rather than fewer new lines. The outcome is that abidiff output sometimes contains extra blank lines which can be confusing. This patch eliminates some of the more obvious cases: - after data member deletions - in enumerator change lists - after "type size hasn't changed" - before listing impacted interfaces A lot of passing of "new line needed" booleans between functions has been eliminated in the process. The patch cleans up the reporting of data members. The code will either emit indentation, a short description and a new line or do nothing at all. The patch also removes some stray location reporting code for array diffs which would have produced some oddly placed output. I could not get this code to trigger as loc = decl->get_location() was never present on the array decls in question. * src/abg-default-reporter.cc (report): In the type_decl_diff, enum_diff, array_diff, class_diff, union_diff and var_diff overrides, simplify new line logic which no longer needs to be threaded through report_name_size_and_alignment_changes. In the distinct_diff override, simplify new line logic which no longer needs to be threaded through report_size_and_alignment_changes. In the enum_diff override, emit just one blank line after each enum. In the array_diff override, remove stray location reporting which doesn't appear to ever trigger; fix new line logic.

Dodji Seketeli	5ed0e40bfd	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.

Dodji Seketeli	080b88c9a1	Implement a [suppress_file] suppression directive ... abidiff, abipkgdiff and abicompat now recognize a [suppress_file] directive in suppression specifications. That directive instructs the tool to avoid loading some binaries altogether. This is the first directive that won't act on the result of the comparison of two binaries. It actually acts earlier and prevents the tool from loading some binaries altogether. The directive looks like: [suppress_file] # Don't load any library named lib_private*.so file_name_regexp = lib_private.*\\.so This prevents the tool from loading (and thus comparing) any library which name matches the pattern "lib_private*.so". [suppress_file] # Only load libraries name lib_public*.so file_name_not_regexp = lib_public.*\\.so This instructs the tool to only load (and compare) files which name match the pattern "lib_public*.so". * doc/manuals/libabigail-concepts.rst: Document the new 'suppress_file' directive. * include/abg-suppression.h (file_suppression): Define new class.

Dodji Seketeli	2f88edd3b3	Fix synthesizing of pointer type ... Libabigail fails to to synthesize a non-existing pointer type to an existing type. This makes abicompat fail in weak mode when trying to detect changes to a function type where the parameter is a pointer to a structure which changed. In the application, the function is invoked and a pointer to the structure is passed to it. It appears that the type of structure is defined in the debug info of the application, but not the pointer to that structure. So abicompat needs to synthesize that pointer to struct in order to synthesize the type of the function, and so, compare it to the type of the function coming from the library. It appears that synthesizing a pointer type (to an existing type) is not supported. Only synthesizing qualified type was supported. This patch adds support for that and thus fixes the abicompat test case that is attached. * include/abg-ir.h: Update copyright. * src/abg-ir.cc (synthesize_type_from_translation_unit): Support synthesizing pointer types. * tests/data/test-abicompat/libtest8-fn-changed-libapp-v0.so: New test input. * tests/data/test-abicompat/libtest8-fn-changed-libapp-v1.so: Likewise. * tests/data/test-abicompat/test8-fn-changed-app: Likewise. * tests/data/test-abicompat/test8-fn-changed-app.c: Likewise. * tests/data/test-abicompat/test8-fn-changed-libapp-v0.c: Likewise. * tests/data/test-abicompat/test8-fn-changed-libapp-v0.h: Likewise. * tests/data/test-abicompat/test8-fn-changed-libapp-v1.c: Likewise. * tests/data/test-abicompat/test8-fn-changed-libapp-v1.h: Likewise. * tests/data/test-abicompat/test8-fn-changed-report-0.txt: Likewise. * tests/data/Makefile.am: Add the new test input files to source distribution. * tests/test-abicompat.cc (in_out_specs): Add the new test inputs above to the test harness.

Dodji Seketeli	0cf1828a90	Fix type synthesis to fix abicompat weak mode ... While looking further in the issue Sinny Kumari reported, I realized that the weak mode wasn't working in that example either. It turned out that synthesizing qualified types was not working because we were just looking them up in the binary, rather than looking up the un-qualified underlying type and then synthezing the resulting qualified type. This patch just does that. * include/abg-fwd.h (synthesize_type_from_translation_unit): Declare new function. (synthesize_function_type_from_translation_unit): Make the translation_unit parameter non-const because the function needs to bind the life time of the synthesized function to the life time of the translation unit.

(synthesize_type_from_translation_unit): Define new function. (synthesize_function_type_from_translation_unit): Make the translation_unit parameter non-const. If the return is void, then take that in account carefuly. Rather than just looking up the type of parameters and return value, synthesize them too, especially when they are qualified types. Bind the life time of the synthesized function type to the lifetime of the translation unit. * tests/data/test-abicompat/test7-fn-changed-report-1.txt: New test reference output. * tests/test-abicompat.cc (in_out_spec): Run the harness on the exisiting test7-fn-changed-app and libtest7-fn-changed-libapp-v1 but in weak mode this time.

Dodji Seketeli	af2a94defa	Fix computing the set of exported functions and varible symbols ... Sinny Kumari reported that abicompat is failing to report ABI changes on a library linked to a small test program.

Fixed thus. * src/abg-ir.cc (elf_symbol::get_name_and_version_from_id): Always set the version and name of the symbol. * src/abg-corpus.cc (corpus::exported_decls_builder::{keep_wrt_id_of_fns_to_keep, keep_wrt_id_of_vars_to_keep}): Reset the symbol name *and* version before passing it.

Dodji Seketeli	8cc7a3e8ef	Make indexes of function parameters start at 1 ... This patch make indexes of a function parameters start at 1, rather at 0 like they used to be.

The number changes itself is not that big, but the number of adjustments to regression test is. * src/abg-comparison.cc (distinct_diff::report): Remove spurious vertical space before reporting size and alignment changes here. (represent): In the variables/data member overload, report type changes first. Then the other changes. (report_size_and_alignment_changes): Make this report array size changes too. Also, make some small adjustments about how type size/alignment changes are introduced. (array_diff::report): Now that report_size_and_alignment_changes() supports size change reporting, just use that function rather than doing it here.

Dodji Seketeli	a102a2f032	Add support for abicompat weak mode ... This patch implements the weak mode of abicompat. In this mode, just the application and the new version of the library are provided. The types of functions and variables of the library that are consumed by the application are compared to the types of the functions and variables expected by the application. The goal is to check if the types of the declarations consumed by the application and provided by the library are compatible with what the application expects. The abicompat first gets the set of symbols undefined in the application and exported by the library. It then builds the set of declarations exported by the library that have those symbols. We call these the set of declarations of the library that are consumed by the application. Note that the debug information for the application does not contain the declarations of the functions/variables whose symbols are undefined. So we can not just read them to compare them to declarations exported by the library. But the *types* of the variables and the *sub-types* of the functions whose symbols are undefined in the application are present in the debug information of the application. So in the weak mode, abicompat compare the *types* of the declarations consumed by the application as expected by the application (described by the debug information of the application) with the types of the declarations exported by the library. To do this a number of changes were necessary. The patch builds a representation of all the types found in the application's debug info. Before that, only the types that are reachable from exported declarations were represented. The abidw tool got a new --load-all-types to test this new ability of loading all types. The patch also adds support for looking a type, not by name, but by its internal representation. In the comparison engine, function_type_diff is introduced to represent changes between two function types. For this, a new class type_or_decl_base has been introduced in the IR. It's now the base class for both decl_base and type_base. And abigail::comparison::diff now takes two pointers of type_or_decl, not decl_base anymore. So function_type_diff can take two function_type now; not that a function_type has no declaration so it doesn't inherit decl_base. A bunch of changes got made just to adjust to this modification. A number of fixes were made too, to make this work, like adding missing comparison operators, removing asserts that too strong, etc.. The patch also adjust the test suite as well as the documentation. * include/abg-fwd.h (class type_or_decl_base): Forward declare this. (is_decl, is_type, is_function_type, get_name, get_type_name) (get_function_type_name, get_pretty_representation) (lookup_function_type_in_corpus, lookup_type_in_translation_unit) (lookup_function_type_in_translation_unit) (synthesize_function_type_from_translation_unit) (hash_type_or_decl): New function declarations. * src/abg-corpus.cc (lookup_type_in_corpus) (lookup_function_type_in_corpus): Define new functions. * include/abg-ir.h (translation_unit::lookup_function_type_in_translation_unit): Declare new friend function.

Dodji Seketeli	19013fd110	Sort functions & variables diff nodes in the diff tree ... Since the work on un-sharing diff tree nodes, it looks like some reports of regression tests on i686 order functions and variables in different orders, leading to test failures on 32 bits platforms because they are different fromthe 64 bits platforms that we use as a reference. This patch sorts (lexicographically) the children diff nodes of a given diff node in general, and also sorts the set of diff nodes for functions and variables that have sub-type changes, in a given corpus_diff.

Dodji Seketeli	817aa5555e	Un-share diff nodes in the comparison IR ... Until now, the diff nodes of the comparison IR were shared. That is, two diffs about the same subjects were represented by the same diff node that would appear twice in the tree. This was preventing us from spotting e.g, the first occurrence of a diff node that would later (in the tree) turn to be redundant because all redundant diff nodes are represented by the same diff node pointer. This patch now makes each diff node be different, as far of pointer comparison is concerned. But it introduces the concept of canonical diff node to ease the comparison between two diff nodes. Two diff nodes that are equal have the same canonical diff node. With this facility, it's now possible to tell the difference between diff nodes that are (structurally) equal. It's not possible to say things like "this is the first or second occurrence of the redundant diff node foo'. * include/abg-ir.h: Prefix the doc string with "///", rather than writing it inside a /**/ comment. * include/abg-comparison.h (function_decl_diff) (function_decl_diff_sptr, fn_parm_diff, fn_parm_diff_sptr) (var_diff_sptr, base_diff, class_diff, class_diff_sptr): Move these class & typedef decls to the top of the file.

Dodji Seketeli	ef7e71febf	Initial implementation of the abicompat tool ... Given an application A that links to a shared library L of version V denoted L(V) and a subsequent version of that library denoted L(V+P), the 'abicompat' tool tells the user if L(V+P) is still ABI compatible with L(V+P). And if it is not, abicompat gives a reports that shows the differences between L(V) and L(V+P) that makes L(V+P) ABI-incompatible with A. The source code of this tool is in the tools/abicompat.cc source file. To support this new tool, this commit changes the comparison engine to optionally avoid showing added symbols that were not referenced by any debug info. It changes the ABI corpus type to allow the specification of a list of variables and functions symbols to keep (and drop all other functions and variables which have other symbols on the floor even before starting to compare the two libraries). This is how the abicompat tool itself works. It basically compares L(V) and L(V+P) but it only looks at their exported functions and variables which symbols are undefined in application A. If the list of exported and defined variables and functions of L(V) whose symbols are undefined in A equals that of L(V+P) (including the sub-types of these variables and functions) A is still compatible with L(V+P). Otherwise, they might not be compatible depending on the kind of differences that are found. * include/abg-comparison.h (diff_context::show_added_symbols_unreferenced_by_debug_info): Declare new accessors.

(corpus::priv::build_unreferenced_symbols_tables): Ensure that the public table of functions/variables is built before doing the work of this function. Also, if a list of variable/function symbols to keep is given, drop all symbols that are not in that list on the floor.
