libstdc++: Implement P2408R5 C++20 iterators as inputs to STL algos
From the paper's abstract: Change the iterator requirements for non-Ranges algorithms. For forward iterators and above that are constant iterators, instead of requiring that iterators meet certain Cpp17...Iterator requirements, require that the iterators model certain iterator concepts. This makes iterators from several standard views usable with non-Ranges algorithms that require forward iterators or above, such as the parallel overloads of most algorithms. This patch narrowly implements P2408R5 in C++23 mode and C++20 mode (as an extension). "Narrowly" because just as in the paper, we don't attempt to relax the requirements of mutable iterators even though it's possible in theory. Note that the PSTL algorithm requirements have already been relaxed in r15-3650. And we don't bother touching the deprecated parallel mode algorithms under ./include/parallel. The main workhorse of this paper is a new helper __iterator_concept_or_category that replaces eligible uses of __iterator_category and iterator_traits::iterator_category. This new helper considers both the iterator_concept and iterator_category of the given iterator and returns the former if it's at least as strong as the latter. It's implemented in terms of the __promotable_iterator concept added in r16-2588 that made std::advance etc aware of C++20 iterators. Note that this helper doesn't check the actual C++20 iterator concepts (which check syntactic requirements along with iterator_concept if it's defined) and instead just checks for, and fully trusts, the iterator_concept defined by the iterator type. This is a slight deviation from the paper but IMHO it's consistent with the existing trusting of iterator_category and should be good enough in practice, though it means C++20 iterators that don't define iterator_concept will not be recognized as such by this helper even if they otherwise model the std::foo_iterator concept. (An undefined iterator_concept effectively defaults to random_access_iterator_tag.) Most of the changes made here are effectively optimizations that don't have a semantic impact, e.g. for std::reduce. I added tests for a couple of algorithms where these changes are observable. The new __iterator_concept_or_category helper can probably also be used to fix PR100070 "Standard library container iterator-pair constructors should check C++20 iterator concepts". As a follow-up to this patch we should either remove the Boost-style concept checks, or relax them accordingly. It seems we're leaning towards removing them outright; see this thread: https://gcc.gnu.org/pipermail/libstdc++/2025-May/061568.html As suggested by Tomasz, this patch also introduces a _GLIBCXX_ITER_MOVE wrapper around ranges::iter_move that also converts to the iterator's value type (and is usable before C++20 as well).

libstdc++: Implement C++23 P2590R2 - Explicit lifetime management [PR106658]
As I can't think of how the middle-end would treat
__builtin_start_lifetime_as other than a blackbox and probably would
need to be implemented as such inline asm in RTL, this patch
just implements it using inline asm in the library.
If not anything else, it can serve as fallback before we and/or clang
get some builtin for it.
Right now the inline asms pretend (potential) read from and write to the whole
memory region and make optimizers forget where the return value points to.
If the optimizers don't know where it points to, I think that should be
good enough, but I'm a little bit afraid of possibly future optimizations
trying to optimize
q->c = 1;
q->d = 2;
auto p = std::start_lifetime_as<S>(q);
if (p == reinterpret_cast<decltype (p)>(q))
return p->a + p->b;
that because of the guarding condition or perhaps assertion we could
simply use the q pointer in MEM_REFs with S type and be surprised by TBAA.
Though if it is a must-alias case, then we should be fine as well.
Though guess that would be the same case with a builtin.

libstdc++: Implement C++26 std::polymorphic [PR119152]
This patch implements C++26 std::polymorphic as specified in P3019 with amendment to move assignment from LWG 4251. The implementation always allocate stored object on the heap. The manager function (_M_manager) is similary keep with the object (polymorphic::_Obj), which reduces the size of the polymorphic to size of the single pointer plus allocator (that is declared with [[no_unique_address]]). The implementation does not not use small-object optimization (SSO). We may consider adding this in the future, as SSO is allowed by the standard. However, storing any polimorphic object will require providing space for two pointers (manager function and vtable pointer) and user-declared data members.

libstdc++: #ifdef out #pragma GCC system_header
In r15-3714-gd3a7302ec5985a I added -Wsystem-headers to the libstdc++ build flags to help catch problems in the library. This patch takes a different approach, of disabling the #pragma system_header unless _GLIBCXX_SYSHDR is defined. As a result, the testsuites will treat them as non-system-headers to get better warning coverage during regression testing of both gcc and libstdc++, not just when building the library. My rationale for the #ifdef instead of just removing the #pragma is the three G++ tests that want to test libstdc++ system header behavior, so we need a way to select it. This doesn't affect installed libraries, as they get their system-header status from the lookup path. But testsuite_flags --build-includes gives -I directives rather than -isystem. This patch doesn't change the headers in config/ because I'm not compiling with most of them, so won't see any warnings that need fixing. Adjusting them could happen later, or we can not bother. libstdc++-v3/ChangeLog: * acinclude.m4 (WARN_FLAGS): Remove -Wsystem-headers. * configure: Regenerate. * include/bits/algorithmfwd.h: #ifdef

libstdc++: Implement std::out_ptr and std::inout_ptr for C++23 [PR111667]
This implements that changes from P1132R8, including optimized paths for std::shared_ptr and std::unique_ptr. For std::shared_ptr we pre-allocate a new control block in the std::out_ptr_t constructor so that the destructor is non-throwing. This requires some care because unlike the shared_ptr(Y*, D, A) constructor, we don't want to invoke the deleter if allocating the control block throws, because we don't own any pointer yet. In order to avoid the unwanted deleter invocation, we create the control block manually. We also want to avoid invoking the deleter on a null pointer on destruction, so we destroy the control block manually if there is no pointer to take ownership of. For std::unique_ptr and for raw pointers, the out_ptr_t object hands out direct access to the pointer, so that we don't have anything to do (except possibly assign a new deleter) in the ~out_ptr_t destructor.

libstdc++: Only declare feature test macros in standard headers
This change moves the definitions of feature test macros (or strictly speaking, the requests for <bits/version.h> to define them) so that only standard headers define them. For example, <bits/shared_ptr.h> will no longer define macros related to std::shared_ptr, only <memory> and <version> will define them. This means that __cpp_lib_shared_ptr_arrays will not be defined by <future> or by other headers that include <bits/shared_ptr.h>. It will only be defined when <memory> has been included. This will discourage users from relying on transitive includes. As a result, internal headers that need to query the macros should use the internal macros like __glibcxx_shared_ptr_arrays instead of __cpp_lib_shared_ptr_arrays, as those internal macros are defined by the internal headers after icluding <bits/version.h>. There are some exceptions to this rule, because __cpp_lib_is_constant_evaluated is defined by bits/c++config.h and so is available everywhere, and __cpp_lib_three_way_comparison is defined by <compare> which several headers are explicitly specified to include, so its macro is guaranteed to be usable too. N.B. not many internal headers actually need an explicit include of <bits/version.h>, because most of them include <type_traits> and so get all the __glibcxx_foo internal macros from there. libstdc++-v3/ChangeLog: * include/bits/algorithmfwd.h: Do not define standard feature test macro here. * include/bits/align.h: Likewise.

libstdc++: Add preprocessor conditions for freestanding [PR106953]
This adds checks for _GLIBCXX_HOSTED to a number of headers which are not currently installed for freestanding, but need to be for P1642R11 support. For example, <iterator> needs to be installed for C++23 freestanding mode, but without stream iterators and streambuf iterators. Similarly, <memory> needs to be installed, but without std::allocator and std::shared_ptr.

libstdc++: Remove unnecessary header from <memory>
Previously <memory> included <bits/stl_algobase.h> so that std::copy, std::fill etc. could be used by <bits/stl_uninitialized.h>.

There's no need to include it in <memory>, where its purpose isn't obvious. libstdc++-v3/ChangeLog: * include/std/memory: Do not include <bits/stl_algobase.h>. |

libstdc++: Reduce header dependencies in and on <memory>
By moving std::make_obj_using_allocator and the related "utility functions for uses-allocator construction" to a new header, we can avoid including the whole of <memory> in <scoped_allocator> and <memory_resource>. In order to simplify the implementation of those utility functions they now use concepts unconditionally. They are no longer defined if __cpp_concepts is not defined. To simplify the code that uses those functions I've introduced a __cpp_lib_make_obj_using_allocator feature test macro (not specified in the standard, which might be an oversight). That allows the code in <memory_resource> and <scoped_allocator> to check the feature test macro to decide whether to use the new utilities, or fall back to the C++17 code. At the same time, this reshuffles some of the headers included by <memory> so that they are (mostly?) self-contained. It should no longer be necessary to include other headers before <bits/shared_ptr.h> when other parts of the library want to use std::shared_ptr without including the whole of <memory>. libstdc++-v3/ChangeLog: * include/Makefile.am: Add new header. * include/Makefile.in: Regenerate. * include/bits/shared_ptr.h: Include <iosfwd>. * include/bits/shared_ptr_base.h: Include required headers here directly, instead of in <memory>. * include/bits/uses_allocator_args.h: New file. Move utility functions for uses-allocator construction from <memory> to here. Only define the utility functions when concepts are available. (__cpp_lib_make_obj_using_allocator): Define non-standard feature test macro. * include/std/condition_variable: Remove unused headers. * include/std/future: Likewise. * include/std/memory: Remove headers that are not needed directly, and are now inclkuded where they're needed. Include new <bits/uses_allocator_args.h> header. * include/std/memory_resource: Include only the necessary headers.

Tweak C++2a uses-allocator construction utilities
The 20_util/scoped_allocator/69293_neg.cc test was failing in C++2a mode because the expected static_assert text wasn't matched. The code is still ill-formed in C++2a, but uses the new __uses_alloc_args function and so fails a different static_assert. This patch adds the same string to the new static_assert, so the test passes. Now that G++ allows concepts to be declared without 'bool' we can use the correct C++2a syntax for the _Std_pair concept used to constrain the uses-allocator construction utilities. Also add a new test to verify that pmr::polymorphic_allocator correctly performs recursive uses-allocator construction for nested pairs in C++2a. * include/std/memory (__uses_alloc_args): Add string-literal to static_assert, to match the one in __uses_alloc. [__cpp_concepts] (_Std_pair): Use C++2a syntax for concept. * testsuite/20_util/polymorphic_allocator/construct_c++2a.cc: Check for recursive uses-allocator construction of nested pairs. * testsuite/20_util/scoped_allocator/construct_pair_c++2a.cc:: Add comment.

Modify some library internals to work without <stdint.h>
std::__detail::__clp2 used uint_fast32_t and uint_fast64_t without checking _GLIBCXX_USE_C99_STDINT_TR1 which was a potential bug. A simpler implementation based on the new std::__ceil2 code performs better and doesn't depend on <stdint.h> types. std::align and other C++11 functions in <memory> where unnecessarily missing when _GLIBCXX_USE_C99_STDINT_TR1 was not defined. * include/bits/hashtable_policy.h (__detail::__clp2): Use faster implementation that doesn't depend on <stdint.h> types. * include/std/memory (align) [!_GLIBCXX_USE_C99_STDINT_TR1]: Use std::size_t when std::uintptr_t is not usable.
