API Evolution and Deprecation History

A list of user-visible changes, in chronological order

3.0

Extensions moved to include/ext.

Include files from the SGI/HP sources that pre-date the ISO standard are added. These files are placed into the include/backward directory and a deprecated warning is added that notifies on inclusion (-Wno-deprecated deactivates the warning.)

Deprecated include backward/strstream added.

Removal of include builtinbuf.h, indstream.h, parsestream.h, PlotFile.h, SFile.h, stdiostream.h, and stream.h.

3.1

Extensions from SGI/HP moved from namespace std to namespace __gnu_cxx. As part of this, the following new includes are added: ext/algorithm, ext/functional, ext/iterator, ext/memory, and ext/numeric.

Extensions to basic_filebuf introduced: __gnu_cxx::enc_filebuf, and __gnu_cxx::stdio_filebuf.

Extensions to tree data structures added in ext/rb_tree.

Removal of ext/tree, moved to backward/tree.h.

3.2

Symbol versioning introduced for shared library.

Removal of include backward/strstream.h.

Allocator changes. Change __malloc_alloc to malloc_allocator and __new_alloc to new_allocator.

For GCC releases from 2.95 through the 3.1 series, defining __USE_MALLOC on the gcc command line would change the default allocation strategy to instead use malloc and free. (This same functionality is now spelled _GLIBCXX_FORCE_NEW, see this page for details.

Error handling in iostreams cleaned up, made consistent.

3.3

3.4

Large file support.

Extensions for generic characters and char_traits added in ext/pod_char_traits.h.

Support for wchar_t specializations of basic_filebuf enhanced to support UTF-8 and Unicode, depending on host. More hosts support basic wchar_t functionality.

Support for char_traits beyond builtin types.

Conformant allocator class and usage in containers. As part of this, the following extensions are added: ext/bitmap_allocator.h, ext/debug_allocator.h, ext/mt_allocator.h, ext/malloc_allocator.h,ext/new_allocator.h, ext/pool_allocator.h.

This is a change from all previous versions, and may require source-level changes due to allocator-related changes to structures names and template parameters, filenames, and file locations. Some, like __simple_alloc, __allocator, __alloc, and _Alloc_traits have been removed.

Default behavior of std::allocator has changed.

Previous versions prior to 3.4 cache allocations in a memory pool, instead of passing through to call the global allocation operators (i.e., __gnu_cxx::pool_allocator). More recent versions default to the simpler __gnu_cxx::new_allocator.

Previously, all allocators were written to the SGI style, and all STL containers expected this interface. This interface had a traits class called _Alloc_traits that attempted to provide more information for compile-time allocation selection and optimization. This traits class had another allocator wrapper, __simple_alloc<T,A>, which was a wrapper around another allocator, A, which itself is an allocator for instances of T. But wait, there's more: __allocator<T,A> is another adapter. Many of the provided allocator classes were SGI style: such classes can be changed to a conforming interface with this wrapper: __allocator<T, __alloc> is thus the same as allocator<T>.

The class allocator used the typedef __alloc to select an underlying allocator that satisfied memory allocation requests. The selection of this underlying allocator was not user-configurable.

Table B.1. Extension Allocators

Allocator (3.4)Header (3.4)Allocator (3.[0-3])Header (3.[0-3])
__gnu_cxx::new_allocator<T>ext/new_allocator.hstd::__new_allocmemory

__gnu_cxx::__mt_alloc<T>ext/mt_allocator.h
__gnu_cxx::bitmap_allocator<T>ext/bitmap_allocator.h

Releases after gcc-3.4 have continued to add to the collection of available allocators. All of these new allocators are standard-style. The following table includes details, along with the first released version of GCC that included the extension allocator.

@ 1.1.1.3 log @import GCC 5.3.0. see these urls for details which are too large to include here: http://gcc.gnu.org/gcc-4.9/changes.html http://gcc.gnu.org/gcc-5/changes.html (note that GCC 5.x is a release stream like GCC 4.9.x, 4.8.x, etc.) the main issues we will have are: The default mode for C is now -std=gnu11 instead of -std=gnu89. ARM: The deprecated option -mwords-little-endian has been removed. The options -mapcs, -mapcs-frame, -mtpcs-frame and -mtpcs-leaf-frame which are only applicable to the old ABI have been deprecated. MIPS: The o32 ABI has been modified and extended. The o32 64-bit floating-point register support is now obsolete and has been removed. It has been replaced by three ABI extensions FPXX, FP64A, and FP64. The meaning of the -mfp64 command-line option has changed. It is now used to enable the FP64A and FP64 ABI extensions. @ text @d80 1 a80 1

4.6

Use constexpr and nullptr where appropriate throughout the library.

The library was updated to avoid including stddef.h in order to reduce namespace pollution.

Reference-count annotations to assist data race detectors.

Added make_exception_ptr as an alias of copy_exception.

4.7

Use of noexcept throughout library.

Partial support for C++11 allocators first appears.

monotonic_clock renamed to steady_clock as required by the final C++11 standard.

A new clocale model for newlib is available.

The library was updated to avoid including unistd.h in order to reduce namespace pollution.

Debug Mode was improved for unordered containers.

4.8

New random number engines and distributions. Optimisations for random.

New --enable-libstdcxx-verbose configure option

The --enable-libstdcxx-time configure option becomes unnecessary given a sufficiently recent glibc.

copy_exception deprecated.

__gnu_cxx::array_allocator deprecated.

5

ABI transition adds new implementations of several components, using the abi_tag attribute and the __cxx11 inline namespace to distinguish the new entities from the old ones.

  • Use of the new or old ABI can be selected per-translation unit with the _GLIBCXX_USE_CXX11_ABI macro.

  • New non-reference-counted string implementation.

  • New list implementation containing a new data member in order to provide O(1) size().

C++11 support completed (movable iostreams, new I/O manipulators, Unicode conversion utilities, atomic operations for shared_ptr, functions for notifying condition variables and making futures ready at thread exit).

Changed formatting of floating point types when ios_base::fixed|ios_base::scientific is set in a stream's format flags.

Improved C++14 support and TS implementations.

New random number engines and distributions.

GDB Xmethods for containers and unique_ptr added.

    C++14 support completed.

    Support for mathematical special functions (ISO/IEC 29124:2010) added.

    Assertions to check function preconditions can be enabled by defining the Macros. The initial set of assertions are a subset of the checks enabled by the Debug Mode, but without the ABI changes and changes to algorithmic complexity that are caused by enabling the full Debug Mode.

    7

    The type of exception thrown by iostreams changed to the cxx11 ABI version of std::ios_base::failure.

    Experimental C++17 support added, including most new library features. The meaning of shared_ptr<T[]> changed to match the C++17 semantics.

    Macros added.

    has_trivial_default_constructor, has_trivial_copy_constructor and has_trivial_copy_assign removed.

    Profile Mode was deprecated.

    7.3

    Including new C++14 or C++17 headers without a suitable -std no longer causes compilation to fail via #error. Instead the header is simply empty and doesn't define anything.

    8

    The exceptions thrown by iostreams can now be caught by handlers for either version of std::ios_base::failure.

    Experimental implementation of the C++17 Filesystem library added.

    AddressSanitizer annotations added to std::vector to detect out-of-range accesses to the unused capacity of a vector.

    std::char_traits<char16_t>::to_int_type(u'\uFFFF') now returns 0xFFFD, as 0xFFFF is used for std::char_traits<char16_t>::eof().

    The extension allowing arithmetic on std::atomic<void*> and types like std::atomic<R(*)()> was deprecated.

    The std::uncaught_exception function was deprecated for C++17 mode.

    The nested typedefs std::hash::result_type and std::hash::argument_type were deprecated for C++17 mode.

    The deprecated iostream members ios_base::io_state, ios_base::open_mode, ios_base::seek_dir, and basic_streambuf::stossc were removed for C++17 mode.

    The non-standard C++0x std::copy_exception function was removed.

    For -std=c++11, -std=c++14, and -std=c++17 modes the <complex.h> header no longer includes the C99 <complex.h> header.

    For the non-default --enable-symvers=gnu-versioned-namespace configuration, the shared library SONAME has been changed to libstdc++.so.8. @ 1.1.1.9 log @initial import of GCC 9.3.0. changes include: - live patching support - shell completion help - generally better diagnostic output (less verbose/more useful) - diagnostics and optimisation choices can be emitted in json - asan memory usage reduction - many general, and specific to switch, inter-procedure, profile and link-time optimisations. from the release notes: "Overall compile time of Firefox 66 and LibreOffice 6.2.3 on an 8-core machine was reduced by about 5% compared to GCC 8.3" - OpenMP 5.0 support - better spell-guesser - partial experimental support for c2x and c++2a - c++17 is no longer experimental - arm AAPCS GCC 6-8 structure passing bug fixed, may cause incompatibility (restored compat with GCC 5 and earlier.) - openrisc support @ text @d15 1 a15 1

    Deprecated features removed:

    • Profile Mode
    • __gnu_cxx::array_allocator

    The non-standard std::__is_nullptr_t type trait was deprecated.

    The std::packaged_task constructors taking an allocator argument are only defined for C++11 and C++14.

    Several members of std::allocator were removed for C++20 mode. The removed functionality has been provided by std::allocator_traits since C++11 and that should be used instead.

    The type of the std::iterator base class of std::istreambuf_iterator was changed to be consistent for all -std modes. Before GCC 10.1 the base class had one type in C++98 mode and a different type in C++11 and later modes. The type in C++98 mode was changed to be the same as for C++11 and later.

    Experimental C++2a support improved, with new headers <concepts>, <ranges>, <compare>, <coroutine>, <numbers>, <span>, and <stop_token> added. @ 1.1.1.10.6.1 log @Sync to head

    The extension allowing containers to be instantiated with an allocator that doesn't match the container's value type is no longer allowed in C++20 mode, even in non-strict -std=gnu++20 mode. @ 1.1.1.12 log @initial import of GCC 12.3.0. major changes in GCC 11 included: - The default mode for C++ is now -std=gnu++17 instead of -std=gnu++14. - When building GCC itself, the host compiler must now support C++11, rather than C++98. - Some short options of the gcov tool have been renamed: -i to -j and -j to -H. - ThreadSanitizer improvements. - Introduce Hardware-assisted AddressSanitizer support. - For targets that produce DWARF debugging information GCC now defaults to DWARF version 5. This can produce up to 25% more compact debug information compared to earlier versions. - Many optimisations. - The existing malloc attribute has been extended so that it can be used to identify allocator/deallocator API pairs. A pair of new -Wmismatched-dealloc and -Wmismatched-new-delete warnings are added. - Other new warnings: -Wsizeof-array-div, enabled by -Wall, warns about divisions of two sizeof operators when the first one is applied to an array and the divisor does not equal the size of the array element. -Wstringop-overread, enabled by default, warns about calls to string functions reading past the end of the arrays passed to them as arguments. -Wtsan, enabled by default, warns about unsupported features in ThreadSanitizer (currently std::atomic_thread_fence). - Enchanced warnings: -Wfree-nonheap-object detects many more instances of calls to deallocation functions with pointers not returned from a dynamic memory allocation function. -Wmaybe-uninitialized diagnoses passing pointers or references to uninitialized memory to functions taking const-qualified arguments. -Wuninitialized detects reads from uninitialized dynamically allocated memory. -Warray-parameter warns about functions with inconsistent array forms. -Wvla-parameter warns about functions with inconsistent VLA forms. - Several new features from the upcoming C2X revision of the ISO C standard are supported with -std=c2x and -std=gnu2x. - Several C++20 features have been implemented. - The C++ front end has experimental support for some of the upcoming C++23 draft. - Several new C++ warnings. - Enhanced Arm, AArch64, x86, and RISC-V CPU support. - The implementation of how program state is tracked within -fanalyzer has been completely rewritten with many enhancements. see https://gcc.gnu.org/gcc-11/changes.html for a full list. major changes in GCC 12 include: - An ABI incompatibility between C and C++ when passing or returning by value certain aggregates containing zero width bit-fields has been discovered on various targets. x86-64, ARM and AArch64 will always ignore them (so there is a C ABI incompatibility between GCC 11 and earlier with GCC 12 or later), PowerPC64 ELFv2 always take them into account (so there is a C++ ABI incompatibility, GCC 4.4 and earlier compatible with GCC 12 or later, incompatible with GCC 4.5 through GCC 11). RISC-V has changed the handling of these already starting with GCC 10. As the ABI requires, MIPS takes them into account handling function return values so there is a C++ ABI incompatibility with GCC 4.5 through 11. - STABS: Support for emitting the STABS debugging format is deprecated and will be removed in the next release. All ports now default to emit DWARF (version 2 or later) debugging info or are obsoleted. - Vectorization is enabled at -O2 which is now equivalent to the original -O2 -ftree-vectorize -fvect-cost-model=very-cheap. - GCC now supports the ShadowCallStack sanitizer. - Support for __builtin_shufflevector compatible with the clang language extension was added. - Support for attribute unavailable was added. - Support for __builtin_dynamic_object_size compatible with the clang language extension was added. - New warnings: -Wbidi-chars warns about potentially misleading UTF-8 bidirectional control characters. -Warray-compare warns about comparisons between two operands of array type. - Some new features from the upcoming C2X revision of the ISO C standard are supported with -std=c2x and -std=gnu2x. - Several C++23 features have been implemented. - Many C++ enhancements across warnings and -f options. see https://gcc.gnu.org/gcc-12/changes.html for a full list. @ text @a318 2

    Calling a std::bind result as volatile was deprecated for C++17. d371 5 a430 3

    The --enable-cheaders=c_std configuration was deprecated. d432 3 a434 44 When compiling as C++20, the operator>> overloads for extracting strings into character buffers only work with arrays, not raw pointers.

    std::string::reserve(n) will no longer reduce the string's capacity. Calling reserve() with no arguments is equivalent to shrink_to_fit(), but is deprecated. shrink_to_fit() should be used instead.

    12

    The std::random_shuffle algorithms are deprecated for C++14 and later. The C++11 std::shuffle algorithm can be used instead.

    The std::unexpected function and related typedef and accessors for the unexpected handler are deprecated for C++11 and later. Dynamic exception specifications should be replaced with noexcept.

    C++98 adaptable function utilities (std::bind1st, std::unary_function, std::ptr_fun, std::mem_fun_ref etc.) were deprecated for C++11. std::iterator, std::raw_storage_iterator, get_temporary_buffer, and std::not_fun were deprecated for C++17.

    Non-standard std::pair constructors were deprecated. A non-standard default argument for vector<bool>::insert(const_iterator, const bool&) was deprecated.

    The bitmap, mt, and pool options for --enable-libstdcxx-allocator were removed. For the new option, std::allocator no longer derives from __gnu_cxx::new_allocator; they both derive from std::__new_allocator instead.

    std::condition_variable::wait changed to be noexcept(false) to allow thread cancellation exceptions to be thrown from pthread_cond_wait without aborting the process.

    Static library libstdc++exp.a was added to provide the symbols for the experimental C++ Contracts support.

    13.3

    Symbols for the Filesystem TS and C++23 <stacktrace> header were added to the static library libstdc++exp.a.
