2022-01-17libstdc++: Define <stacktrace> header for C++23Jonathan Wakely1-0/+7
Add the <stacktrace> header and a new libstdc++_libbacktrace.a library that provides the implementation. For now, the new library is only built if --enable-libstdcxx-backtrace=yes is used. As with the Filesystem TS, the new library is only provided as a static archive. libstdc++-v3/ChangeLog: * acinclude.m4 (GLIBCXX_ENABLE_BACKTRACE): New macro. * configure.ac: Use GLIBCXX_ENABLE_BACKTRACE. * include/Makefile.am: Add new header. * include/Makefile.in: Regenerate. * include/std/stacktrace: New header. * include/std/version (__cpp_lib_stacktrace): Define. * Makefile.in: Regenerate. * config.h.in: Regenerate. * configure: Regenerate. * doc/Makefile.in: Regenerate. * libsupc++/Makefile.in: Regenerate. * po/Makefile.in: Regenerate. * python/Makefile.in: Regenerate. * src/Makefile.am: Regenerate. * src/Makefile.in: Regenerate. * src/c++11/Makefile.in: Regenerate. * src/c++17/Makefile.in: Regenerate. * src/c++20/Makefile.in: Regenerate. * src/c++98/Makefile.in: Regenerate. * src/filesystem/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. * src/libbacktrace/Makefile.am: New file. * src/libbacktrace/Makefile.in: New file. * src/libbacktrace/backtrace-rename.h: New file. * src/libbacktrace/backtrace-supported.h.in: New file. * src/libbacktrace/config.h.in: New file. * testsuite/lib/libstdc++.exp (check_effective_target_stacktrace): New proc. * testsuite/20_util/stacktrace/entry.cc: New test. * testsuite/20_util/stacktrace/synopsis.cc: New test. * testsuite/20_util/stacktrace/version.cc: New test.
2022-01-10libstdc++: Fix and simplify freestanding configuration [PR103866]Jonathan Wakely1-0/+1
This fixes the --disable-hosted-libstdcxx build so that it works with --without-headers. Currently you need to also use --with-newlib, which is confusing for users who aren't actually using newlib. The AM_PROG_LIBTOOL checks are currently skipped for --with-newlib and --with-avrlibc builds, with this change they are also skipped when using --without-headers. It would be nice if using --disable-hosted-libstdcxx automatically skipped those checks, but GLIBCXX_ENABLE_HOSTED comes too late to make the AM_PROG_LIBTOOL checks depend on $is_hosted. The checks for EOF, SEEK_CUR etc. cause the build to fail if there is no <stdio.h> available. Unlike most headers, which get a HAVE_FOO_H macro, <stdio.h> is in autoconf's default includes, so every check tries to include it unconditionally. This change skips those checks for freestanding builds. Similarly, the checks for <stdint.h> types done by GCC_HEADER_STDINT try to include <stdio.h> and fail for --without-headers builds. This change skips the use of GCC_HEADER_STDINT for freestanding. We can probably stop using GCC_HEADER_STDINT entirely, since only one file uses the gstdint.h header that is generated, and that could easily be changed to use <stdint.h> instead. That can wait for stage 1. We also need to skip the GLIBCXX_CROSSCONFIG stage if --without-headers was used, since we don't have any of the functions it deals with. The end result of the changes above is that it should not be necessary for a --disable-hosted-libstdcxx --without-headers build to also use --with-newlib. Finally, compile libsupc++ with -ffreestanding when --without-headers is used, so that <stdint.h> will use <gcc-stdint.h> instead of expecting it to come from libc. libstdc++-v3/ChangeLog: PR libstdc++/103866 * acinclude.m4 (GLIBCXX_COMPUTE_STDIO_INTEGER_CONSTANTS): Do nothing for freestanding builds.

2021-11-04libstdc++: Fix pretty printing of std::unique_ptr [PR103086]Jonathan Wakely2-21/+52
Since std::tuple started using [[no_unique_address]] the tuple<T*, D> member of std::unique_ptr<T, D> has two _M_head_impl subobjects, in different base classes. That means this printer code is ambiguous: tuple_head_type = tuple_impl_type.fields()[1].type # _Head_base head_field = tuple_head_type.fields()[0] if head_field.name == '_M_head_impl': self.pointer = tuple_member['_M_head_impl'] In older versions of GDB it happened to work by chance, because GDB returned the last _M_head_impl member and std::tuple's base classes are stored in reverse order, so the last one was the T* element of the tuple. Since GDB 11 it returns the first _M_head_impl, which is the deleter element. The fix is for the printer to stop using an ambiguous field name and cast the tuple to the correct base class before accessing the _M_head_impl member. Instead of fixing this in both UniquePointerPrinter and StdPathPrinter a new unique_ptr_get function is defined to do it correctly. That is defined in terms of new tuple_get and _tuple_impl_get functions. It would be possible to reuse _tuple_impl_get to access each element in StdTuplePrinter._iterator.__next__, but that already does the correct casting, and wouldn't be much simpler anyway. libstdc++-v3/ChangeLog: PR libstdc++/103086 * python/libstdcxx/v6/printers.py (_tuple_impl_get): New helper for accessing the tuple element stored in a _Tuple_impl node.

2021-08-18libstdc++: Fix vector<bool> printer tests to work in debug modeJonathan Wakely1-5/+5
This fixes a compilation error in debug mode, due to std::_Bit_reference not being defined, because it's in namespace std::__cxx1998 instead. We can refer to it as vector<bool>::reference instead, which always works. That fixes some compilation errors in debug mode, but the tests fail at run-time instead because the printers for vector<bool> helpers are only registered for the std namespace, not std::__cxx1998. That is fixed by using add_container to register the printers instead of add_version, as the former registers them in the std and std::__cxx1998 namespaces. Signed-off-by: Jonathan Wakely <jwakely@redhat.com> libstdc++-v3/ChangeLog: * python/libstdcxx/v6/printers.py (StdBitReferencePrinter): Use 'std::vector<bool>::reference' as type name, not _Bit_reference.

2021-08-16libstdc++: Install GDB pretty printers for debug libraryJonathan Wakely2-2/+18
The additional libraries installed by --enable-libstdcxx-debug are built without optimization to aid debugging, but the Python pretty printers are not installed alongside them. This means that you can step through the unoptimized library code, but at the expense of pretty printing the library types. This remedies the situation by installing another copy of the GDB hooks alongside the debug version of libstdc++.so. Signed-off-by: Jonathan Wakely <jwakely@redhat.com> libstdc++-v3/ChangeLog: * python/Makefile.am [GLIBCXX_BUILD_DEBUG] (install-data-local): Install another copy of the GDB hook. * python/Makefile.in: Regenerate.

2021-04-21libstdc++: Install libstdc++*-gdb.py more robustly [PR 99453]Philippe Blain2-28/+6
In order for GDB to auto-load the pretty printers, they must be installed as "libstdc++.$ext-gdb.py", where 'libstdc++.$ext' is the name of the object file that is loaded by GDB [1], i.e. the libstdc++ shared library. The approach taken in libstdc++-v3/python/Makefile.am is to loop over files matching 'libstdc++*' in $(DESTDIR)$(toolexeclibdir) and choose the last file matching that glob that is not a symlink, the Libtool '*.la' file or a Python file. That works fine for ELF targets where the matching names are: libstdc++.a libstdc++.so libstdc++.so.6 libstdc++.so.6.0.29 But not for macOS with: libstdc++.6.dylib libstdc++.a Or MinGW with: libstdc++-6.dll libstdc++.dll.a Try to make a better job at installing the pretty printers with the correct name by copying the approach taken by isl [2], that is, using a sed invocation on the Libtool-generated 'libstdc++.la' to read the correct name for the current platform.

2021-03-11libstdc++: Fix find_type helper to work consistentlyJonathan Wakely1-2/+2
The find_type helper function sometimes results in "class X::name" and lookup for that fails. For more details see "Problem 1" in https://gcc.gnu.org/pipermail/libstdc++/2021-March/052132.html and the example at https://sourceware.org/bugzilla/show_bug.cgi?id=27510#c2 This patch replaces typ.unqualified() with typ.tag, which is never qualified, and will never include the 'class' or 'struct' keywords. Using the .tag attribute should be safe here because we know we are looking at a class type and we've already used strip_typedefs(). libstdc++-v3/ChangeLog: * python/libstdcxx/v6/printers.py (find_type): Use tag attribute instead of unqualified() method.

2020-12-16libstdc++: Add C++ runtime support for new 128-bit long double formatJonathan Wakely1-1/+5
This adds support for the new __ieee128 long double format on powerpc64le targets. Most of the complexity comes from wanting a single libstdc++.so library that contains the symbols needed by code compiled with both -mabi=ibmlongdouble and -mabi=ieeelongdouble (and not forgetting -mlong-double-64 as well!) In a few places this just requires an extra overload, for example std::from_chars has to be overloaded for both forms of long double. That can be done in a single translation unit that defines overloads for 'long double' and also '__ieee128', so that user code including <charconv> will be able to link to a definition for either type of long double. Those are the easy cases. The difficult parts are (as for the std::string ABI transition) the I/O and locale facets. In order to be able to write either form of long double to an ostream such as std::cout we need the locale to contain a std::num_put facet that can handle both forms. The same approach is taken as was already done for supporting 64-bit long double and 128-bit long double: adding extra overloads of do_put to the facet class. On targets where the new long double code is enabled, the facets that are registered in the locale at program startup have additional overloads so that they can work with any long double type. Where this fails to work is if user code installs its own facet, which will probably not have the additional overloads and so will only be able to output one or the other type. In practice the number of users expecting to be able to use their own locale facets in code using a mix of -mabi=ibmlongdouble and -mabi=ieeelongdouble is probably close to zero. libstdc++-v3/ChangeLog: * Makefile.in: Regenerate. * config.h.in: Regenerate. * config/abi/pre/gnu.ver: Make patterns less greedy. * config/os/gnu-linux/ldbl-ieee128-extra.ver: New file with patterns for IEEE128 long double symbols. * configure: Regenerate. * configure.ac: Enable alternative 128-bit long double format on powerpc64*-*-linux*. * doc/Makefile.in: Regenerate. * fragment.am: Regenerate. * include/Makefile.am: Set _GLIBCXX_LONG_DOUBLE_ALT128_COMPAT. * include/Makefile.in: Regenerate. * include/bits/c++config: Define inline namespace for new long double symbols.

2020-01-24Add `--with-toolexeclibdir=' configuration optionMaciej W. Rozycki1-0/+1

2019-11-29libstdc++:: improve how pretty printers find node types (PR 91997)Jonathan Wakely1-40/+98
This fixes two related problems. The iterators for node-based containers use nested typedefs such as std::list<T>::iterator::_Node to denote their node types. As reported in https://bugzilla.redhat.com/show_bug.cgi?id=1053438 those typedefs are not always present in the debug info. That means the pretty printers cannot find them using gdb.lookup_type (via the find_type helper). Instead of looking up the nested typedefs this patch makes the printers look up the actual class templates directly. A related problem (and the original topic of PR 91997) is that GDB fails to find types via gdb.lookup_type when printing a backtrace from a non-C++ functiion: https://sourceware.org/bugzilla/show_bug.cgi?id=25234 That is also solved by not looking up the nested typedef.

2019-02-27PR libstdc++/89466 avoid slow xsltproc command in configureJonathan Wakely1-0/+1
Certain broken versions of xsltproc ignore the --nonet option and will attempt to fetch the docbook stylesheet from the WWW when it isn't in the local XML catalog. This patch checks for the local stylesheet directory first, and doesn't use xsltproc if no local stylesheets are found. Checking for the local directory is done using xmlcatalog if available, only checking the hardcoded list of directories if xmlcatalog fails. The right directory for Suse is added to the hardcoded list. This should avoid doing an xsltproc check that would need to download the stylesheet, so no network connection is made even if a broken xsltproc is present.

2019-01-08PR libstdc++/87855 fix optional for types with non-trivial copy/moveJonathan Wakely1-7/+17
When the contained value is not trivially copy (or move) constructible the union's copy (or move) constructor will be deleted, and so the _Optional_payload delegating constructors are invalid. G++ fails to diagnose this because it incorrectly performs copy elision in the delegating constructors. Clang does diagnose it (llvm.org/PR40245). The solution is to avoid performing any copy (or move) when the contained value's copy (or move) constructor isn't trivial. Instead the contained value can be constructed by calling _M_construct. This is OK, because the relevant constructor doesn't need to be constexpr when the contained value isn't trivially copy (or move) constructible. Additionally, this patch removes a lot of code duplication in the _Optional_payload partial specializations and the _Optional_base partial specialization, by hoisting it into common base classes. The Python pretty printer for std::optional needs to be adjusted to support the new layout. Retain support for the old layout, and add a test to verify that the support still works.

2018-12-13PR libstdc++/71044 optimize std::filesystem::path constructionJonathan Wakely1-2/+73
This new implementation has a smaller footprint than the previous implementation, due to replacing std::vector<_Cmpt> with a custom pimpl type that only needs a single pointer. The _M_type enumeration is also combined with the pimpl type, by using a tagged pointer, reducing sizeof(path) further still. Construction and modification of paths is now done more efficiently, by splitting the input into a stack-based buffer of string_view objects instead of a dynamically-allocated vector containing strings. Once the final size is known only a single allocation is needed to reserve space for it. The append and concat operations no longer require constructing temporary path objects, nor re-parsing the entire native pathname. This results in algorithmic improvements to path construction, and working with large paths is much faster.

2018-11-23PR libstdc++/87308 adjust regex used in std::any pretty printerJonathan Wakely1-1/+1
The pretty printer for std::any fails when the contained value is a locally-defined type, because the name in the debuginfo has cv-qualifiers and ptr-declarators in different positions. The unexpected format confuses the printer. This makes the printer's regex handle either format. This isn't a complete fix because looking up the contained type fails when there are two types with the same name (defined in different local scopes). This applies to all closure types defined in a given function, as they all appear as "func()::lambda" in the debuginfo names.

2018-10-31Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856).Joseph Myers1-37/+88
This patch updates GCC to use autoconf 2.69 and automake 1.15.1. (That's not the latest automake version, but it's the one used by binutils-gdb, with which consistency is desirable, and in any case seems a useful incremental update that should make a future update to 1.16.1 easier.) The changes are generally similar to the binutils-gdb ones, and are copied from there where shared files and directories are involved (there are some further changes to such shared directories, however, which I'd expect to apply to binutils-gdb once this patch is in GCC). Largely, obsolete AC_PREREQ calls are removed, while many AC_LANG_SOURCE calls are added to avoid warnings from aclocal and autoconf. Multilib support is no longer included in core automake, meaning that multilib.am needs copying from automake's contrib directory into the GCC source tree. Autoconf 2.69 has Go support, so local copies of that support are removed. I hope the D support will soon be submitted to upstream autoconf so the local copy of that can be removed in a future update. Changes to how automake generates runtest calls mean quotes are removed from RUNTEST definitions in five lib*/testsuite/Makefile.am files (libatomic, libgomp, libitm, libphobos, libvtv; some others have RUNTEST definitions without quotes, which are still OK); libgo and libphobos also get -Wno-override added to AM_INIT_AUTOMAKE so those overrides of RUNTEST do not generate automake warnings. Note that the regeneration did not include regeneration of fixincludes/config.h.in (attempting such regeneration resulted in all the USED_FOR_TARGET conditionals disappearing; and I don't see anything in the fixincludes/ directory that would result in such conditionals being generated, unlike in the gcc/ directory). Also note that libvtv/testsuite/other-tests/Makefile.in was not regenerated; that directory is not listed as a subdirectory for which Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm not sure how it's meant to be regenerated. While I mostly fixed warnings should running aclocal / automake / autoconf, there were various such warnings from automake in the libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos directories that I did not fix, preferring to leave those to the relevant subsystem maintainers. Specifically, most of those warnings were of the following form (example from libgfortran): Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory, Makefile.am:48: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled. For now, the corresponding output automake: object file(s) will be placed in the top-level directory. However, automake: this behaviour will change in future Automake versions: they will automake: unconditionally cause object files to be placed in the same subdirectory automake: of the corresponding sources. automake: You are advised to start using 'subdir-objects' option throughout your automake: project, to avoid future incompatibilities. I think it's best for the relevant maintainers to add subdir-objects and do any other associated Makefile.am changes needed. In some cases the paths in the warnings involved ../; I don't know if that adds any extra complications to the use of subdir-objects. I've tested this with native, cross and Canadian cross builds. The risk of any OS-specific issues should I hope be rather lower than if a libtool upgrade were included (we *should* do such an upgrade at some point, but it's more complicated - it involves identifying all our local libtool changes to see if any aren't included in the upstream version we update to, and reverting an upstream libtool patch that's inappropriate for use in GCC); I think it would be better to get this update into GCC so that people can test in different configurations and we can fix any issues found, rather than to try to get more and more testing done before it goes in. top level: 2018-10-31 Joseph Myers <joseph@codesourcery.com> PR bootstrap/82856 * multilib.am: New file.

2018-10-09Define std::string and related typedefs outside __cxx11 namespaceJonathan Wakely1-1/+3
The typedefs for common specializations of std::__cxx11::basic_string do not need to be in the std::__cxx11 namespace. Those typedefs are never used for linkage purposes so don't appear in mangled names, and so don't need to be distinct from the equivalent typedefs for the COW std::basic_string specializations. It is OK for the same typedef to refer to different types in different translation units. Defining them directly in namespace std improves diagnostics that use those typedefs. For example: error: could not convert '1' from 'int' to 'std::__cxx11::string' {aka 'std::__cxx11::basic_string<char>'} will now be printed as: error: could not convert '1' from 'int' to 'std::string' {aka 'std::__cxx11::basic_string<char>'} The precise type is still shown, but the typedef is not obfuscated with the inline namespace. * include/bits/stringfwd.h (string, wstring, u16string, u32string): Define typedefs outside of __cxx11 inline namespace. * python/libstdcxx/v6/printers.py (register_type_printers): Also register printers for typedefs in new location.

2018-07-31PR libstdc++/86751 default assignment operators for std::pairJonathan Wakely1-0/+34
The solution for PR 77537 causes ambiguities due to the extra copy assignment operator taking a __nonesuch_no_braces parameter. By making the base class non-assignable we don't need the extra deleted overload in std::pair. The copy assignment operator will be implicitly deleted (and the move assignment operator not declared) as needed. Without the additional user-provided operator in std::pair the ambiguity is avoided.

2018-07-17PR libstdc++/86450 use -Wabi=2 and simplify -Werror useJonathan Wakely1-2/+1
Use -Wabi=2 to fix warnings about -Wabi having no effect on its own. This requires suppressing two warnings in src/c++11/debug.cc which do not affect the library ABI. Previously libstdc++ defaulted to --enable-werror but the -Werror flag was not actually added unless --enable-maintainer-mode was used. This is not documented and not the expected behaviour. This removes any special treatment for maintainer-mode, makes -Werror depend directly on --enable-werror, and changes the default to --enable-werror=no.
