PR libstdc++/89102 implement new common_type rules (P0435R1, P0548R1) This change ensures that std::common_type<> is a complete type (LWG 2408), and that std::common_type<T>, std::common_type<cv T1, cv T2>, and std::common_type<T1, T2, R...> will use program-defined specializations for std::common_type<T1, T2> (LWG 2465). The implementation of common_type<T1, T2, R...> is changed to use void_t, and the specializations for duration and time_point are modified to also use void_t instead of depending on implementation details of common_type.

Update libstdc++ Doxygen config The GROUP_NESTED_COMPOUNDS option means that types nested inside inline namespaces or other classes will be automatically added to a Doxygen group, e.g. this actually works as intended: /** * @defgroup chrono Time * @ingroup utilities * * Classes and functions for time. * @{ */ namespace chrono { template<typename _Rep, typename _Period = ratio<1>> struct duration; template<typename _Clock, typename _Dur = typename _Clock::duration> struct time_point; } /// @} Currently chrono::duration and chrono::time_point are not added to the "chrono" group. They would need an explicit @ingroup tag added to them individually. With GROUP_NESTED_COMPOUNDS=YES they get added to the enclosing group. The SORT_BY_SCOPE_NAME option means that the list of classes will sort by class name, not the full qualified-id. Currently the alphabetical Class List for classes beginning with 'c' looks like: char_traits (__gnu_cxx) character (__gnu_cxx) condition_base (__gnu_cxx) const_iterator_ condition_variable_any (std::_V2) cauchy_distribution (std) char_traits (std) i.e. the list is sorted by the namespaces first, then the class names. This is not helpful when you don't know which namespace a class might be in, and inline namespaces with reserved names are not hidden (see https://github.com/doxygen/doxygen/issues/5914 for a feature request to allow that). With SORT_BY_SCOPE_NAME=NO the list looks like: cauchy_distribution (std) char_traits (__gnu_cxx) char_traits (std) character (__gnu_cxx) condition_base (__gnu_cxx) condition_variable_any (std::_V2) const_iterator_ This allows you to find a class by name more easily. Also add PREDEFINED macros so that __attribute__ and various macros like _GLIBCXX_NO_DISCARD, _GLIBCXX14_CONSTEXPR don't appear in the generated docs. * doc/doxygen/user.cfg.in: Regenerate with Doxygen 1.8.14 and set GROUP_NESTED_COMPOUNDS=YES and SORT_BY_SCOPE_NAME=NO. Add various _GLIBCXX_xxx macros and __attribute__(X) to PREDEFINED macros that Doxygen expands. From-SVN: r270802

Adjust Doxygen processing of pb_ds containers Several of the pb_ds headers are intended to be included multiple times, within the definition of various class templates. The including files define macros like PB_DS_CLASS_C_DEC and PB_DS_GEN_POS before including these headers. In some cases the types defined in the headers are actually nested types within other classes, and so should not have been documented as though they are declared in the global namespace, as in: https://gcc.gnu.org/onlinedocs/gcc-8.3.0/libstdc++/api/a12028.html In other cases the headers provide inline member function definitions, but when processed by Doxygen the class name "PB_DS_CLASS_C_DEC" is not recognised. This patch makes Doxygen ignore definitions that only make sense when included in the right context with the right macros defined. * include/ext/pb_ds/detail/bin_search_tree_/*_imps.hpp: Do not define anything unless PB_DS_CLASS_C_DEC is defined. * include/ext/pb_ds/detail/binary_heap_/*_imps.hpp: Likewise. * include/ext/pb_ds/detail/binomial_heap_/*_imps.hpp: Likewise. * include/ext/pb_ds/detail/binomial_heap_base_/*_imps.hpp: Likewise. * include/ext/pb_ds/detail/cc_hash_table_map_/*_imps.hpp: Likewise. * include/ext/pb_ds/detail/gp_hash_table_map_/*_imps.hpp: Likewise. * include/ext/pb_ds/detail/hash_fn/*_imp.hpp: Likewise. * include/ext/pb_ds/detail/left_child_next_sibling_heap_/*_imps.hpp: Likewise. * include/ext/pb_ds/detail/list_update_map_/*_imps.hpp: Likewise. * include/ext/pb_ds/detail/ov_tree_map_/*_imps.hpp: Likewise. * include/ext/pb_ds/detail/pairing_heap_/*_imps.hpp: Likewise. * include/ext/pb_ds/detail/pat_trie_/*_imps.hpp: Likewise. * include/ext/pb_ds/detail/rb_tree_map_/*_imps.hpp: Likewise. * include/ext/pb_ds/detail/rc_binomial_heap_/*_imps.hpp: Likewise. * include/ext/pb_ds/detail/resize_policy*_imp.hpp: Likewise. * include/ext/pb_ds/detail/splay_tree_/*_imps.hpp: Likewise. * include/ext/pb_ds/detail/thin_heap_/*_imps.hpp: Likewise. * include/ext/pb_ds/detail/trie_policy*_imp.hpp: Likewise. * include/ext/pb_ds/detail/unordered_iterator/const_iterator.hpp: Likewise. * include/ext/pb_ds/detail/unordered_iterator/iterator.hpp: Likewise. * include/ext/pb_ds/detail/unordered_iterator/point_const_iterator.hpp: Likewise. * include/ext/pb_ds/detail/unordered_iterator/point_iterator.hpp: Likewise.

Update libstdc++ Doxygen config The GROUP_NESTED_COMPOUNDS option means that types nested inside inline namespaces or other classes will be automatically added to a Doxygen group, e.g. this actually works as intended: /** * @defgroup chrono Time * @ingroup utilities * * Classes and functions for time. * @{ */ namespace chrono { template<typename _Rep, typename _Period = ratio<1>> struct duration; template<typename _Clock, typename _Dur = typename _Clock::duration> struct time_point; } /// @} Currently chrono::duration and chrono::time_point are not added to the "chrono" group. They would need an explicit @ingroup tag added to them individually. With GROUP_NESTED_COMPOUNDS=YES they get added to the enclosing group. The SORT_BY_SCOPE_NAME option means that the list of classes will sort by class name, not the full qualified-id. Currently the alphabetical Class List for classes beginning with 'c' looks like: char_traits (__gnu_cxx) character (__gnu_cxx) condition_base (__gnu_cxx) const_iterator_ condition_variable_any (std::_V2) cauchy_distribution (std) char_traits (std) i.e. the list is sorted by the namespaces first, then the class names. This is not helpful when you don't know which namespace a class might be in, and inline namespaces with reserved names are not hidden (see https://github.com/doxygen/doxygen/issues/5914 for a feature request to allow that). With SORT_BY_SCOPE_NAME=NO the list looks like: cauchy_distribution (std) char_traits (__gnu_cxx) char_traits (std) character (__gnu_cxx) condition_base (__gnu_cxx) condition_variable_any (std::_V2) const_iterator_ This allows you to find a class by name more easily. Also add PREDEFINED macros so that __attribute__ and various macros like _GLIBCXX_NO_DISCARD, _GLIBCXX14_CONSTEXPR don't appear in the generated docs. * doc/doxygen/user.cfg.in: Regenerate with Doxygen 1.8.14 and set GROUP_NESTED_COMPOUNDS=YES and SORT_BY_SCOPE_NAME=NO.

Fix basic_string_view typedefs and enforce preconditions The basic_string_view::pointer and basic_string_view::reference typedefs are supposed to refer to the non-const value type. In previous standards having traits_type::char_type different to value_type was simply undefined, but in the C++2a draft it's ill-formed, as changed by P1148R0. For std::basic_string and iostreams we might want to only enforce this conditionally for __cplusplus > 201703L but for std::basic_string_view we don't have backwards compatibility concerns. Also add assertions to verify the _CharT argument is a "char-like" type (non-array, trivial, standard layout type). Also remove the non-standard basic_string_view::_M_check and basic_string_view::_M_limit member functions, replacing them with non-member functions that will still exist even if basic_string_view is specialized by the program. * include/experimental/string_view (basic_string_view::pointer) (basic_string_view::reference): Fix to refer to non-const value_type. * include/bits/basic_string.h (basic_string): Use __sv_check and __sv_limit instead of basic_string_view::_M_check and basic_string_view::_M_limit. * include/std/string_view (__sv_check, __sv_limit): New helper functions to replace basic_string_view::_M_check and basic_string_view::_M_limit.

Fix std::variant regression caused by never-valueless optimization A regression was introduced by the recent changes to provide the strong exception safety guarantee for "never valueless" types that have O(1), non-throwing move assignment. The problematic code is: else if constexpr (__detail::__variant::_Never_valueless_alt<type>()) { // This construction might throw: variant __tmp(in_place_index<_Np>, __il, std::forward<_Args>(__args)...); // But _Never_valueless_alt<type> means this won't: *this = std::move(__tmp); } When the variant is not assignable, the assignment is ill-formed, so should not be attempted. When the variant has a copy assignment operator but not a move assignment operator, the assignment performs a copy assignment and that could throw, so should not be attempted. The solution is to only take that branch when the variant has a move assignment operator, which is determined by the _Traits::_S_move_assign constant. When that is false the strong exception safety guarantee is not possible, and so the __never_valueless function should also depend on _S_move_assign. While testing the fixes for this I noticed that the partial specialization _Never_valueless_alt<basic_string<C,T,A>> incorrectly assumed that is_nothrow_move_constructible<basic_string<C,T,A>> is always true, but that's wrong for fully-dynamic COW strings. Fix the partial specialization, and improve the comment describing _Never_valueless_alt to be clear it depends on move construction as well as move assignment. Finally, I also observed that _Variant_storage<false, T...>::_M_valid() was not taking advantage of the __never_valueless<T...>() function to avoid a runtime check. Only the _Variant_storage<true, T...>::_M_valid() function was using __never_valueless. That is also fixed.

PR libstdc++/87431 re-adjust never-valueless optimizations Avoid creating arbitrarily large objects on the stack when emplacing trivially copyable objects into a variant. Currently we provide the strong exception-safety guarantee for all trivially copyable types, by constructing a second variant and then doing a non-throwing move assignment from the temporary. This patch restricts that behaviour to trivially copyable types that are no larger than 256 bytes. For larger types the object will be emplaced directly into the variant, and if its initialization throws then the variant becomes valueless. Also implement Antony Polukhin's suggestion to whitelist specific types that are not trivially copyable but can be efficiently move-assigned. Emplacing those types will never cause a variant to become valueless. The whitelisted types are: std::shared_ptr, std::weak_ptr, std::unique_ptr, std::function, and std::any. Additionally, std::basic_string, std::vector, and __gnu_debug::vector are whitelisted if their allocator traits give them a non-throwing move assignment operator. Specifically, this means std::string is whitelisted, but std::pmr::string is not.

PR libstdc++/85965 delay static assertions until types are complete The static assertions added for PR libstdc++/48101 were at class scope and so were evaluated too eagerly, when it might not be possible to determine whether the function objects are invocable with the key types. The problematic cases are where the key type is not known to be convertible to the argument type(s) of the function object until later, after a type has been completed. Specifically, if the key type is a pointer to a derived class and the function object's argument type is a pointer to a base class, then the derived-to-base conversion is only valid once the derived type is complete. By moving the static assertions to the destructor they will only be evaluated when the destructor is instantiated, at which point whether the key type can be passed to the function object should be knowable. The ideal place to do the checks would be only when the function objects are actually invoked, but that would mean adding the checks in numerous places, so the destructor is used instead. The tests need to be adjusted because the "required from here" line is now the location of the destructor, not the point of instantiation in the test file. For the map and multimap tests which check two specializations, the dg-error matching the assertion text matches both cases. Also check the diagnostic output for the template arguments, to ensure both specializations trigger the assertion.

In C++17 <math.h> should not put special functions in global namespace IS 29124 8.2 [sf.mathh] says that <math.h> should add the names of the special functions to the global namespace. However, C++17 Annex D [depr.c.headers] excludes those functions explicitly, so they should not be placed in the global namespace unconditionally for C++17. Only add them to the global namespace when IS 29124 is explicitly requested via the __STDCPP_WANT_MATH_SPEC_FUNCS__ macro. * include/c_compatibility/math.h [!__STDCPP_WANT_MATH_SPEC_FUNCS__] (assoc_laguerre, assoc_laguerref, assoc_laguerrel, assoc_legendre) (assoc_legendref, assoc_legendrel, beta, betaf, betal, comp_ellint_1) (comp_ellint_1f, comp_ellint_1l, comp_ellint_2, comp_ellint_2f) (comp_ellint_2l, comp_ellint_3, comp_ellint_3f, comp_ellint_3l) (cyl_bessel_i, cyl_bessel_if, cyl_bessel_il, cyl_bessel_j) (cyl_bessel_jf, cyl_bessel_jl, cyl_bessel_k, cyl_bessel_kf) (cyl_bessel_kl, cyl_neumann, cyl_neumannf, cyl_neumannl, ellint_1) (ellint_1f, ellint_1l, ellint_2, ellint_2f, ellint_2l, ellint_3) (ellint_3f, ellint_3l, expint, expintf, expintl, hermite, hermitef) (hermitel, laguerre, laguerref, laguerrel, legendre, legendref) (legendrel, riemann_zeta, riemann_zetaf, riemann_zetal, sph_bessel) (sph_besself, sph_bessell, sph_legendre, sph_legendref, sph_legendrel) (sph_neumann, sph_neumannf, sph_neumannl): Only add using-declarations when the special functions IS is enabled, not for C++17. * testsuite/26_numerics/headers/cmath/functions_global_c++17.cc: Replace with ... * testsuite/26_numerics/headers/cmath/functions_global.cc: New test, without checks for special functions in C++17. * testsuite/26_numerics/headers/cmath/special_functions_global.cc: New test.

PR libstdc++/89466 avoid slow xsltproc command in configure 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.

DR 2586 fix value category in uses-allocator checks Because uses-allocator construction is invariably done with a const lvalue the __uses_alloc helper should use a const lvalue for the is_constructible checks. Otherwise, it can detect that the type can be constructed from an rvalue, and then an error happens when a const lvalue is passed to the constructor instead. Prior to LWG DR 2586 scoped_allocator_adaptor incorrectly used an rvalue type in the is_constructible check and then used a non-const lvalue for the actual construction. The other components using uses-allocator construction (tuple and polymorphic_allocator) have always done so with a const lvalue allocator, although the use of __use_alloc in our implementation meant they behaved the same as scoped_allocator_adaptor and incorrectly used rvalues for the is_constructible checks. In C++20 the P0591R4 changes mean that all uses-allocator construction is defined in terms of the new uses_allocator_construction_args functions, which always use a const lvalue allocator. The changes in this patch ensure that the __use_alloc helper correctly matches the requirements in the standard, consistently using a const lvalue allocator for the is_constructible checks and the actual constructor arguments. * doc/xml/manual/intro.xml: Document LWG 2586 status. * include/bits/uses_allocator.h (__uses_alloc): Use const lvalue allocator type in is_constructible checks. * testsuite/20_util/scoped_allocator/69293_neg.cc: Adjust dg-error. * testsuite/20_util/scoped_allocator/dr2586.cc: New test. * testsuite/20_util/tuple/cons/allocators.cc: Add test using problematic type from LWG 2586 discussion. * testsuite/20_util/uses_allocator/69293_neg.cc: Adjust dg-error. * testsuite/20_util/uses_allocator/cons_neg.cc: Likewise.

PR libstdc++/89130 restore support for non-MoveConstructible types The changes to "relocate" std::vector elements can lead to new errors outside the immediate context, because moving the elements to new storage no longer makes use of the move-if-noexcept utilities. This means that types with deleted moves no longer degenerate to copies, but are just ill-formed. The errors happen while instantiating the noexcept-specifier for __relocate_object_a, when deciding whether to try to relocate. This patch introduces indirections to avoid the ill-formed instantiations of std::__relocate_object_a. In order to avoid using if-constexpr prior to C++17 this is done by tag dispatching. After this patch all uses of std::__relocate_a are guarded by checks that will support sensible code (i.e. code not using custom allocators that fool the new checks).

PR libstdc++/88782 avoid ODR problems in std::make_shared The old version of _Sp_counted_ptr_inplace::_M_get_deleter (up to GCC 8.2.0) expects to be passed a real std::typeinfo object, so mixing that with the new definition of the __shared_ptr constructor (which always passes the fake tag) leads to accessing the fake object as a real std::typeinfo. Instead of trying to make it safe to mix the old and new definitions, just stop using that function. By passing a reference to __shared_ptr::_M_ptr to the __shared_count constructor it can be set directly, without needing to obtain the pointer via the _M_get_deleter back-channel. This avoids a virtual dispatch (which fixes PR 87514). This means that code built against new libstdc++ headers doesn't use _M_get_deleter at all, and so make_shared works the same whether RTTI is enabled or not. Also change _M_get_deleter so that it checks for a real type_info object even when RTTI is disabled, by calling a library function. Unless libstdc++ itself is built without RTTI that library function will be able to test if it's the right type_info. This means the new definition of _M_get_deleter can handle both the fake type_info tag and a real type_info object, even if built without RTTI. If linking to objects built against older versions of libstdc++ then if all objects use -frtti or all use -fno-rtti, then the caller of _M_get_deleter and the definition of _M_get_deleter will be consistent and it will work. If mixing -frtti with -fno-rtti it can still fail if the linker picks an old definition of _M_get_deleter and an old __shared_ptr constructor that are incompatible. In that some or all objects might need to be recompiled.

P0357R3 reference_wrapper for incomplete types This patch implements the C++2a proposal to allow incomplete types in std::reference_wrapper, which was previously undefined. The change cannot be implemented for earlier standards, because prior to C++2a std::reference_wrapper has a weak result type, so must inspect the template argument to see if it defines a nested result_type member. That is deprecated (but still required) in C++17, and removed from C++2a. The removal of the base class from reference_wrapper is a potential ABI change, as it could alter the layout of a type which derives from reference_wrapper<T> and from an empty type with _Weak_result_type<T> as a base class. Previously the repeated _Weak_result_type<T> base class would have prevented the empty base-class optimization, but if reference_wrapper<T> no longer derives from it, the empty class could be placed at the same address as the reference_wrapper<T> base. In practice, the only types which derive from _Weak_result_type or from _Reference_wrapper_base_memfun or any of its base classes are non-empty types defined in libstdc++: std::reference_wrapper, std::function, and std::_Bind. As they are non-empty types, they are not eligible for EBO anyway. * include/bits/refwrap.h [__cplusplus > 201703L] (_Refwrap_base_arg1, _Refwrap_base_arg2, _Reference_wrapper_base) (_Reference_wrapper_base_memfun): Do not define for C++2a.

PR libstdc++/87855 fix optional for types with non-trivial copy/move 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.

PR libstdc++/86756 Move rest of std::filesystem to libstdc++.so Move std::filesystem directory iterators and operations from libstdc++fs.a to main libstdc++ library. These components have many dependencies on OS support, which is not available on all targets. Some additional autoconf checks and conditional compilation is needed to ensure the files will build for all targets. Previously this code was not compiled without --enable-libstdcxx-filesystem-ts but the C++17 components should be available for all hosted builds. The tests for these components no longer need to link to libstdc++fs.a, but are not expected to pass on all targets. To avoid numerous failures on targets which are not expected to pass the tests (due to missing OS functionality) leave the dg-require-filesystem-ts directives in place for now. This will ensure the tests only run for builds where the filesystem-ts library is built, which presumably means some level of OS support is present.

PR libstdc++/87431 fix regression introduced by r264574 The previous patch for PR 87431 assumed that initialing a scalar type could not throw, but it can obtain its value via a conversion operator, which could throw. This meant the variant could get into a valueless state, but the valueless_by_exception() member function would always return false. This patch fixes it by changing the emplace members to have strong exception safety when initializing a contained value of trivially copyable type. The _M_valid() member gets a corresponding change to always return true for trivially copyable types, not just scalar types. Strong exception safety (i.e. never becoming valueless) is achieved by only replacing the current contained value once any potentially throwing operations have completed. If constructing the new contained value can throw then a new std::variant object is constructed to hold it, and then move-assigned to *this (which won't throw).

Fix bugs in filesystem::path::lexically_normal() Using path::_List::erase(const_iterator) to remove a non-final component in path::lexically_normal() is a bug, because it leaves the following component with an incorrect _M_pos value. Instead of providing erase members that allow removing components from the middle, replace them with pop_back() and _M_erase_from(const_iterator) which only allow removing elements at the end. Most uses of erase are unaffected, because they only remove elements from the end anyway. The one use of erasure from the middle in lexically_normal() is replaced by calls to pop_back() and/or clearing the last component to leave it as an empty final filename. Also replace the "???" comment in lexically_normal() to document when that branch is taken. * include/bits/fs_path.h (path::_List::erase): Replace both overloads with ...
