Fix non-standard behaviour of std::istream_iterator The current implementation of istream_iterator allows the iterator to be reused after reaching end-of-stream, so that subsequent reads from the stream can succeed (e.g. if the stream state has been cleared and stream position changed from EOF). The P0738R2 paper clarified that the expected behaviour is to set the stream pointer to null after reaching end-of-stream, preventing further reads. This implements that requirement, and adds the new default constructor to std::ostream_iterator. * include/bits/stream_iterator.h (istream_iterator::_M_equal()): Make private. (istream_iterator::_M_read()): Do not check stream state before attempting extraction. Set stream pointer to null when extraction fails (P0738R2). (operator==(const istream_iterator&, const istream_iterator&)): Change to be a hidden friend of istream_iterator. (operator!=(const istream_iterator&, const istream_iterator&)): Likewise. (ostream_iterator::ostream_iterator()): Add default constructor. (ostream_iterator::ostream_iterator(ostream_type*, const C*)): Use addressof. * testsuite/24_iterators/istream_iterator/1.cc: New test. * testsuite/24_iterators/ostream_iterator/1.cc: New test. * testsuite/24_iterators/ostream_iterator/70766.cc: Also check constructor taking a string. * testsuite/24_iterators/ostream_iterator/requirements/constexpr.cc: New test.

Have std::vector printer's iterator return bool for vector<bool> Have the pretty-printer for 'std::vector<bool>' return a value of type 'bool' rather than an 'int'. This way, the type is clear and that can be used for better display and a 'gdb.Value' constructed from the returned value will have type 'bool' again, not e.g. 'long long' as happened previously (at least with GDB 8.2.1 on amd64). 2019-06-19 Michael Weghorn <m.weghorn@posteo.de> Jonathan Wakely <jwakely@redhat.com> PR libstdc++/90945 * python/libstdcxx/v6/printers.py (StdVectorPrinter._iterator): Use values of type bool for vector<bool> elements. * testsuite/libstdc++-prettyprinters/simple.cc: Test vector<bool>. * testsuite/libstdc++-prettyprinters/simple11.cc: Likewise.

PR libstdc++/90920 restore previous checks for empty ranges The change in r263433 broke the contract of the __rotate functions, by no longer accepting empty ranges. That means that callers which inlined the old version of std::rotate (without checks) that end up linking to a new definition of std::__rotate (also without checks) could perform a divide by zero and crash. This restores the old contract of the __rotate overloads. PR libstdc++/90920 partially revert r263433 * include/bits/stl_algo.h (__rotate): Restore checks for empty ranges.

PR libstdc++/90281 Fix string conversions for filesystem::path Fix several bugs in the encoding conversions for filesystem::path that prevent conversion of Unicode characters outside the Basic Multilingual Plane, and prevent returning basic_string specializations with alternative allocator types. The std::codecvt_utf8 class template is not suitable for UTF-16 conversions because it uses UCS-2 instead. For conversions between UTF-8 and UTF-16 either std::codecvt<C, char, mbstate> or codecvt_utf8_utf16<C> must be used.

Simplify node ownership in _Hashtable members Introduce an RAII type to manage nodes in unordered containers while they are being inserted. If the caller always owns a node until it is inserted, then the insertion functions don't need to deallocate on failure. This allows a FIXME in the node re-insertion API to be removed. Also change extract(const key_type&) to not call extract(const_iterator) anymore. This avoids looping through the bucket nodes again to find the node before the one being extracted. 2019-06-17 François Dumont <fdumont@gcc.gnu.org> Jonathan Wakely <jwakely@redhat.com> * include/bits/hashtable.h (struct _Hashtable::_Scoped_node): New type.

Replace std::to_string for integers with optimized version The std::to_chars functions from C++17 can be used to implement std::to_string with much better performance than calling snprintf. Only the __detail::__to_chars_len and __detail::__to_chars_10 functions are needed for to_string, because it always outputs base 10 representations. The return type of __detail::__to_chars_10 should not be declared before C++17, so the function body is extracted into a new function that can be reused by to_string and __detail::__to_chars_10. The existing tests for to_chars rely on to_string to check for correct answers. Now that they use the same code that doesn't actually ensure correctness, so add new tests for std::to_string that compare against printf output. * include/Makefile.am: Add new <bits/charconv.h> header. * include/Makefile.in: Regenerate. * include/bits/basic_string.h (to_string(int), to_string(unsigned)) (to_string(long), to_string(unsigned long), to_string(long long)) (to_string(unsigned long long)): Rewrite to use __to_chars_10_impl. * include/bits/charconv.h: New header.

Refactor SFINAE constraints on std::tuple constructors Replace the _TC class template with the better-named _TupleConstraints one, which provides a different set of member functions. The new members do not distinguish construction from lvalues and rvalues, but expects the caller to do that by providing different template arguments. Within the std::tuple primary template and std::tuple<T1, T2> partial specialization the _TupleConstraints members are used via new alias templates like _ImplicitCtor and _ExplicitCtor which makes the constructor constraints less verbose and repetitive. For example, where we previously had: template<typename... _UElements, typename enable_if< _TMC<_UElements...>::template _MoveConstructibleTuple<_UElements...>() && _TMC<_UElements...>::template _ImplicitlyMoveConvertibleTuple<_UElements...>() && (sizeof...(_Elements) >= 1), bool>::type=true> constexpr tuple(_UElements&&... __elements) We now have: template<typename... _UElements, bool _Valid = __valid_args<_UElements...>(), _ImplicitCtor<_Valid, _UElements...> = true> constexpr tuple(_UElements&&... __elements) There are two semantic changes as a result of the refactoring: - The allocator-extended default constructor is now constrained. - The rewritten constraints fix PR 90700. * include/std/tuple (_TC): Replace with _TupleConstraints.

Fix tests that fail in C++2a mode The GNU extension that allows using the wrong allocator type with a container is disabled for C++2a mode, because the standard now requires a diagnostic. Fix the tests that fail when -std=gnu++2a is used. Also remove some reundant tests that are duplicates of another test except for a target specifier of c++11. Those tests previously set -std=gnu++11 explicitly but that was replaced globally with a target specifier. These tests existed to verify that explicit instantiation worked for both C++98 and C++11 modes, but now do nothing because both copies of the test use -std=gnu++14 by default. Instead of duplicating the test we should be regularly running the whole testsuite with different -std options. * testsuite/23_containers/deque/requirements/explicit_instantiation/ 1_c++0x.cc: Remove redundant test. * testsuite/23_containers/deque/requirements/explicit_instantiation/ 2.cc: Use target selector instead of preprocessor condition. * testsuite/23_containers/deque/requirements/explicit_instantiation/ 3.cc: Do not run test for C++2a. * testsuite/23_containers/forward_list/requirements/ explicit_instantiation/3.cc: Likewise. * testsuite/23_containers/forward_list/requirements/ explicit_instantiation/5.cc: Do not test allocator rebinding extension for C++2a. * testsuite/23_containers/list/requirements/explicit_instantiation/ 1_c++0x.cc: Remove redundant test. * testsuite/23_containers/list/requirements/explicit_instantiation/ 2.cc: Use target selector instead of preprocessor condition. * testsuite/23_containers/list/requirements/explicit_instantiation/ 3.cc: Do not run test for C++2a. * testsuite/23_containers/list/requirements/explicit_instantiation/ 5.cc: Do not test allocator rebinding extension for C++2a. * testsuite/23_containers/map/requirements/explicit_instantiation/ 1_c++0x.cc: Remove redundant test. * testsuite/23_containers/map/requirements/explicit_instantiation/ 2.cc: Adjust comment. * testsuite/23_containers/map/requirements/explicit_instantiation/ 3.cc: Do not run test for C++2a. * testsuite/23_containers/map/requirements/explicit_instantiation/ 5.cc: Do not test allocator rebinding extension for C++2a. * testsuite/23_containers/multimap/requirements/explicit_instantiation/ 1_c++0x.cc: Remove redundant test. * testsuite/23_containers/multimap/requirements/explicit_instantiation/ 3.cc: Do not run test for C++2a. * testsuite/23_containers/multimap/requirements/explicit_instantiation/ 5.cc: Do not test allocator rebinding extension for C++2a. * testsuite/23_containers/multiset/requirements/explicit_instantiation/ 3.cc: Do not run test for C++2a. * testsuite/23_containers/multiset/requirements/explicit_instantiation/ 5.cc: Do not test allocator rebinding extension for C++2a. * testsuite/23_containers/set/requirements/explicit_instantiation/3.cc: Do not run test for C++2a. * testsuite/23_containers/set/requirements/explicit_instantiation/ 1_c++0x.cc: Remove redundant test. * testsuite/23_containers/set/requirements/explicit_instantiation/5.cc: Do not test allocator rebinding extension for C++2a. * testsuite/23_containers/unordered_map/requirements/ explicit_instantiation/3.cc: Likewise. * testsuite/23_containers/unordered_map/requirements/ explicit_instantiation/5.cc: Do not test allocator rebinding extension for C++2a. * testsuite/23_containers/unordered_multimap/requirements/ explicit_instantiation/3.cc: Do not run test for C++2a. * testsuite/23_containers/unordered_multimap/requirements/ explicit_instantiation/5.cc: Do not test allocator rebinding extension for C++2a. * testsuite/23_containers/unordered_multiset/requirements/ explicit_instantiation/3.cc: Do not run test for C++2a. * testsuite/23_containers/unordered_multiset/requirements/ explicit_instantiation/5.cc: Do not test allocator rebinding extension for C++2a. * testsuite/23_containers/unordered_set/requirements/ explicit_instantiation/3.cc: Do not run test for C++2a. * testsuite/23_containers/unordered_set/requirements/ explicit_instantiation/5.cc: Do not test allocator rebinding extension for C++2a. * testsuite/23_containers/vector/ext_pointer/explicit_instantiation/ 2.cc: Remove redundant test. * testsuite/23_containers/vector/ext_pointer/explicit_instantiation/ 3.cc: Do not run test for C++2a. * testsuite/23_containers/vector/requirements/explicit_instantiation/ 3.cc: Likewise.

Enforce allocator::value_type consistency for containers in C++2a In previous standards it is undefined for a container and its allocator to have a different value_type. Libstdc++ has traditionally allowed it as an extension, automatically rebinding the allocator to the container's value_type. Since GCC 8.1 that extension has been disabled for C++11 and later when __STRICT_ANSI__ is defined (i.e. for -std=c++11, -std=c++14, -std=c++17 and -std=c++2a). Since the acceptance of P1463R1 into the C++2a draft an incorrect allocator::value_type now requires a diagnostic. This patch implements that by enabling the static_assert for -std=gnu++2a as well. * doc/xml/manual/status_cxx2020.xml: Document P1463R1 status. * include/bits/forward_list.h [__cplusplus > 201703]: Enable allocator::value_type assertion for C++2a. * include/bits/hashtable.h: Likewise. * include/bits/stl_deque.h: Likewise. * include/bits/stl_list.h: Likewise. * include/bits/stl_map.h: Likewise. * include/bits/stl_multimap.h: Likewise. * include/bits/stl_multiset.h: Likewise. * include/bits/stl_set.h: Likewise. * include/bits/stl_vector.h: Likewise. * testsuite/23_containers/deque/48101-3_neg.cc: New test. * testsuite/23_containers/forward_list/48101-3_neg.cc: New test. * testsuite/23_containers/list/48101-3_neg.cc: New test. * testsuite/23_containers/map/48101-3_neg.cc: New test. * testsuite/23_containers/multimap/48101-3_neg.cc: New test. * testsuite/23_containers/multiset/48101-3_neg.cc: New test. * testsuite/23_containers/set/48101-3_neg.cc: New test. * testsuite/23_containers/unordered_map/48101-3_neg.cc: New test. * testsuite/23_containers/unordered_multimap/48101-3_neg.cc: New test. * testsuite/23_containers/unordered_multiset/48101-3_neg.cc: New test. * testsuite/23_containers/unordered_set/48101-3_neg.cc: New test. * testsuite/23_containers/vector/48101-3_neg.cc: New test.

Libstdc++ has traditionally allowed it as an extension, automatically rebinding the allocator to the container's value_type. Since GCC 8.1 that extension has been disabled for C++11 and later when __STRICT_ANSI__ is defined (i.e. for -std=c++11, -std=c++14, -std=c++17 and -std=c++2a). Since the acceptance of P1463R1 into the C++2a draft an incorrect allocator::value_type now requires a diagnostic. This patch implements that by enabling the static_assert for -std=gnu++2a as well. * doc/xml/manual/status_cxx2020.xml: Document P1463R1 status. * include/bits/forward_list.h [__cplusplus > 201703]: Enable allocator::value_type assertion for C++2a. * include/bits/hashtable.h: Likewise. * include/bits/stl_deque.h: Likewise. * include/bits/stl_list.h: Likewise. * include/bits/stl_map.h: Likewise. * include/bits/stl_multimap.h: Likewise. * include/bits/stl_multiset.h: Likewise. * include/bits/stl_set.h: Likewise. * include/bits/stl_vector.h: Likewise. * testsuite/23_containers/deque/48101-3_neg.cc: New test. * testsuite/23_containers/forward_list/48101-3_neg.cc: New test. * testsuite/23_containers/list/48101-3_neg.cc: New test. * testsuite/23_containers/map/48101-3_neg.cc: New test. * testsuite/23_containers/multimap/48101-3_neg.cc: New test. * testsuite/23_containers/multiset/48101-3_neg.cc: New test. * testsuite/23_containers/set/48101-3_neg.cc: New test. * testsuite/23_containers/unordered_map/48101-3_neg.cc: New test. * testsuite/23_containers/unordered_multimap/48101-3_neg.cc: New test. * testsuite/23_containers/unordered_multiset/48101-3_neg.cc: New test. * testsuite/23_containers/unordered_set/48101-3_neg.cc: New test. * testsuite/23_containers/vector/48101-3_neg.cc: New test.

PR libstdc++/71579 assert that type traits are not misused with incomplete types This patch adds static asserts for type traits misuse with incomplete classes and unions. This gives a nice readable error message instead of an UB and odr-violations. Some features of the patch: * each type trait has it's own static_assert inside. This gives better diagnostics than the approach with putting the assert into a helper structure and using it in each trait. * the result of completeness check is not memorized by the compiler. This gives no false positive after the first failed check. * some of the compiler builtins already implement the check. But not all of them! So the asserts are in all the type_traits that may benefit from the check. This also makes the behavior of libstdc++ more consistent across different (non GCC) compilers. * std::is_base_of does not have the assert as it works well in many cases with incomplete types 2019-05-31 Antony Polukhin <antoshkka@gmail.com> PR libstdc++/71579 * include/std/type_traits __type_identity, __is_complete_or_unbounded): New helpers for checking preconditions in traits.

PR libstdc++/85494 use rdseed and rand_s in std::random_device Add support for additional sources of randomness to std::random_device, to allow using RDSEED for Intel CPUs and rand_s for Windows. When supported these can be selected using the tokens "rdseed" and "rand_s". For *-w64-mingw32 targets the "default" token will now use rand_s, and for other i?86-*-* and x86_64-*-* targets it will try to use "rdseed" first, then "rdrand", and finally "/dev/urandom". To simplify the declaration of std::random_device in <bits/random.h> the constructors now unconditionally call _M_init instead of _M_init_pretr1, and the function call operator now unconditionally calls _M_getval. The library code now decides whether _M_init and _M_getval should use a real source of randomness or the mt19937 engine. Existing code compiled against old libstdc++ headers will still call _M_init_pretr1 and _M_getval_pretr1, but those functions now forward to _M_init and _M_getval if a real source of randomness is available. This means existing code compiled for mingw-w64 will start to use rand_s just by linking to a new libstdc++.dll. * acinclude.m4 (GLIBCXX_CHECK_X86_RDSEED): Define macro to check if the assembler supports rdseed. * config.h.in: Regenerate. * configure: Regenerate. * configure.ac: Use GLIBCXX_CHECK_X86_RDSEED. * config/os/mingw32-w64/os_defines.h (_GLIBCXX_USE_CRT_RAND_S): Define. * doc/html/*: Regenerate. * doc/xml/manual/status_cxx2011.xml: Document new tokens. * include/bits/random.h (random_device::random_device()): Always call _M_init rather than _M_init_pretr1.

PR libstdc++/85494 use rdseed and rand_s in std::random_device Add support for additional sources of randomness to std::random_device, to allow using RDSEED for Intel CPUs and rand_s for Windows. When supported these can be selected using the tokens "rdseed" and "rand_s". For *-w64-mingw32 targets the "default" token will now use rand_s, and for other i?86-*-* and x86_64-*-* targets it will try to use "rdseed" first, then "rdrand", and finally "/dev/urandom". To simplify the declaration of std::random_device in <bits/random.h> the constructors now unconditionally call _M_init instead of _M_init_pretr1, and the function call operator now unconditionally calls _M_getval. The library code now decides whether _M_init and _M_getval should use a real source of randomness or the mt19937 engine. Existing code compiled against old libstdc++ headers will still call _M_init_pretr1 and _M_getval_pretr1, but those functions now forward to _M_init and _M_getval if a real source of randomness is available. This means existing code compiled for mingw-w64 will start to use rand_s just by linking to a new libstdc++.dll. * acinclude.m4 (GLIBCXX_CHECK_X86_RDSEED): Define macro to check if the assembler supports rdseed. * config.h.in: Regenerate. * configure: Regenerate. * configure.ac: Use GLIBCXX_CHECK_X86_RDSEED. * config/os/mingw32-w64/os_defines.h (_GLIBCXX_USE_CRT_RAND_S): Define. * doc/html/*: Regenerate. * doc/xml/manual/status_cxx2011.xml: Document new tokens. * include/bits/random.h (random_device::random_device()): Always call _M_init rather than _M_init_pretr1.

From what I understand of the libstdc++/83237 thread at <https://gcc.gnu.org/ml/gcc-patches/2017-12/msg00573.html>, the high numbers are not arbitrary, so it seems wrong to try lowering them, or we'd just waste cycles testing nothing, or worse, ending up with a bogus error indication. Better to just plain disable this part of the test for simulator targets; I assume the results should be the same on any IEEE-float target, i.e. no target-specific things going on here that'd raise a need to cover it everywhere. With this part of the test disabled, I saw the test finishing in (time) "124.74s user" where it was before "1120.26s user" running the cris-elf-run simulator on a "i7-4770K CPU @ 3.50GHz" host. Most certainly that indidates that the remainder of the test is still too much for *some* host+simulator combos, but I'm happy with the runtime lowered to 1/5 of the timeout (10 minutes) on this particular combination, and I'd think this fixes timeouts for many other simulator combos too. This construct (disabling or lowering limits for simulators) is used elsewhere in the libstdc++ test-suite and in particular the SIMULATOR_TEST macro is used in the testsuite machinery (though AFAICT not in testDiscreteDist). * testsuite/26_numerics/random/poisson_distribution/operators/values.cc: Don't run the libstdc++/83237 part on simulator targets.

PR libstdc++/77691 fix resource_adaptor failures due to max_align_t bugs Remove the hardcoded whitelist of allocators expected to return memory aligned to alignof(max_align_t), because that doesn't work when the platform's malloc() and GCC's max_align_t do not agree what the largest fundamental alignment is.

PR libstdc++/77691 fix resource_adaptor failures due to max_align_t bugs Remove the hardcoded whitelist of allocators expected to return memory aligned to alignof(max_align_t), because that doesn't work when the platform's malloc() and GCC's max_align_t do not agree what the largest fundamental alignment is. It's also sub-optimal for user-defined allocators that return memory suitable for any fundamental alignment. Instead use a hardcoded list of alignments that are definitely supported by the platform malloc, and use a copy of the allocator rebound to a POD type with the requested alignment. Only allocate an oversized buffer to use with std::align for alignments larger than any of the hardcoded values. For 32-bit Solaris x86 do not include alignof(max_align_t) in the hardcoded values.

Make std::match_results::_M_resize more useful As both callers of match_results::_M_resize(unsigned) immediately follow it with a loop to update the value of each sub_match, that behaviour can be moved into _M_resize itself. The first caller fills the container with unmatched subs, which can be done with vector::assign, and the second caller clears the container to establish a specific state, which can be provided by a new member function specific to that purpose. Tangentially, I also noticed that match_results::max_size() doesn't account for the three special sub_match objects that are always present in a fully established result state. This patch also fixes that. * include/bits/regex.h (match_results::max_size()): Adjust return value to account for prefix/suffix/unmatched subs. (match_results::_M_resize(unsigned int)): Use _Base_type::assign to reset the contained sub matches.

PR libstdc++/81266 fix std::thread::native_handle_type test The test uses remove_pointer because in most cases native_handle_type is a pointer to the actual type that the C++ class contains. However, for std::thread, native_handle_type is the same type as the type contained in std::thread, and so remove_pointer is not needed. On targets where pthread_t is a pointer type remove_pointer<native_handle_type> is not a no-op, instead it transforms pthread_t and causes the test to fail. The fix is to not apply remove_pointer when testing std::thread. PR libstdc++/81266 * testsuite/util/thread/all.h: Do not use remove_pointer for std::thread::native_handle_type. From-SVN: r271080

PR libstdc++/90314 fix non-equivalent declarations of std::swap In order to use the _GLIBCXX_NOEXCEPT_IF macro for an expression containing commas I enclosed it in parentheses, so the preprocessor wouldn't treat it as two arguments to the function-like macro. Clang gives an error because now the noexcept-specifier noexcept((C)) is not equivalent to the noexcept(C) one on the declaration of swap in <type_traits>. Instead of requiring extra parentheses around the expression, redefine _GLIBCXX_NOEXCEPT_IF as a variadic macro (even though supporting that in C++98 is a GNU extension).

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.

PR libstdc++/61761 fix std::proj for targets without C99 cproj The current generic implementation of __complex_proj used when cproj is not available calculates the wrong projection, giving a different result than given by C99's cproj. When C99 cproj is not available but isinf and copysign are, use those to give correct results for float, double and long double. Otherwise, and for other specializations of std::complex, just use a generic version that returns its argument, and so doesn't support infinities. We might want to consider adding additional overloads of __complex_proj to support extended types such as _Float64x, _Float128 etc. PR libstdc++/61761 * include/std/complex (__complex_proj): Return parameter unchanged.

Reduce code instantiated by filesystem::path::_S_convert_loc Jakub noted in https://gcc.gnu.org/ml/libstdc++/2019-04/msg00140.html that an unwanted std::wstring::_M_replace_dispatch symbol has started to be exported from the Fedora shared library. This symbol is triggered by the instantiation of std::wstring::assign(const char*, const char*) from std::__str_codecvt_in which is called from path::_S_convert_loc. The branch that triggers that instantiation can't actually happen in that case, because codecvt facets will only return noconv when the input and output types are the same.

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.

Fix condition for std::variant to be copy constructible The standard says the std::variant copy constructor is defined as deleted unless all alternative types are copy constructible, but we were making it also depend on move constructible. Fix the condition and enhance the tests to check the semantics with pathological copy-only types (i.e. supporting copying but having deleted moves). The enhanced tests revealed a regression in copy assignment for non-trivial alternative types, where the assignment would not be performed because the condition in the _Copy_assign_base visitor is false: is_same_v<remove_reference_t<T&>, remove_reference_t<const T&>>. * include/std/variant (__detail::__variant::_Traits::_S_copy_assign): Do not depend on whether all alternative types are move constructible.

PR libstdc++/90046 fix build failure on epiphany-elf The epiphany-elf target aligns structs to 8 bytes, which causes the static_assert(alignof(_Chunk) == 1) to fail. Instead of requiring _Chunks to be positionable at any alignment, ensure new buffers are aligned to alignof(_Chunk). Because the buffer size is a power of two, we know that both the buffer size and sizeof(_Chunk) are multiples of alignof(_Chunk). So is p is aligned to alignof(_Chunk) then so is (p + size - sizeof(_Chunk)). So just ensure the new buffer is aligned to at least alignof(_Chunk), which should already be true because the caller requests at least alignof(max_align_t).

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. As part of this patch, additional if-constexpr branches are added for the cases where the initialization is known to be non-throwing (so the overhead of the try-catch block can be avoided) and where a scalar is being produced by a potentially-throwing conversion operator (so that the overhead of constructing and move-assigning a variant is avoided). These changes should have no semantic effect, just better codegen.

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. As part of this patch, additional if-constexpr branches are added for the cases where the initialization is known to be non-throwing (so the overhead of the try-catch block can be avoided) and where a scalar is being produced by a potentially-throwing conversion operator (so that the overhead of constructing and move-assigning a variant is avoided). These changes should have no semantic effect, just better codegen.

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++/89345 Only define std::destroying_delete for C++2a Clang defines the __cpp_impl_destroying_delete macro unconditionally, so that the feature is supported whenever the library type is defined. This is incompatible with the current definition in libstdc++ because we use constexpr and inline variables, which will give an error for older -std modes. This patch defines the destroying_delete_t type and destroying_delete variable independently of the __cpp_impl_destroying_delete macro, but only for C++2a (because the names aren't reserved for previous standards). The __cpp_lib_destroying_delete macro is only defined when both the library type and compiler macro are defined (i.e. when the type can actually be used as intended).

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.

Pretty printer test fixes and improvements Test that StdUniquePtrPrinter correctly prints std::unique_ptr objects using the old layout, prior to the PR libstdc++/77990 changes. The printer test for a valueless std::variant started to fail because the PR libstdc++/87431 fix meant it no longer became valueless. Change the test to use a type that is not trivially copyable, so that the exception causes it to become valueless. * testsuite/libstdc++-prettyprinters/compat.cc: Test printer support for old std::unique_ptr layout. * testsuite/libstdc++-prettyprinters/cxx17.cc: Fix std::variant test to become valueless.

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.

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).

Define new filesystem::__file_clock type In C++17 the clock used for filesystem::file_time_type is unspecified, allowing it to be chrono::system_clock. The C++2a draft requires it to be a distinct type, with additional member functions to convert to/from other clocks (either the system clock or UTC).

This meant that the extern template declarations had to be disabled for C++17 mode.

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.

Add more testcases for class template argument deduction of maps This adds additional tests for std::map and std::multimap CTAD. The tests ensure that deduction works for braced-init-list of value_type objects, and for pairs of input iterators (with both std::pair<Key, T> and value_type as the iterator's value_type). This ensures deduction from value_type still works, as well as the non-value_type cases in LWG 3025. Similar tests for unordered maps do not work, apparently because the constructor taking an initializer_list<value_type> is not usable for deduction, and the deduction guide taking initializer_list<pair<Key, T>> deduces key_type to be const. I am not addressing that. * testsuite/23_containers/map/cons/deduction.cc: Test deduction from initializer_list<value_type> and from input iterator ranges. * testsuite/23_containers/multimap/cons/deduction.cc: Likewise.
