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++: Fix <numeric> parallel algos for move-only values [PR117905]
All of reduce, transform_reduce, exclusive_scan, and inclusive_scan, transform_exclusive_scan, and transform_inclusive_scan have a precondition that the type of init meets the Cpp17MoveConstructible requirements. It isn't required to be copy constructible, so when passing it to the next internal function it needs to be moved, not copied. We also need to move when creating local variables on the stack, and when returning as part of a pair. libstdc++-v3/ChangeLog: PR libstdc++/117905 * include/pstl/glue_numeric_impl.h (reduce, transform_reduce) (transform_reduce, inclusive_scan, transform_exclusive_scan) (transform_inclusive_scan): Use std::move for __init parameter. * include/pstl/numeric_impl.h (__brick_transform_reduce) (__pattern_transform_reduce, __brick_transform_scan) (__pattern_transform_scan): Likewise. * include/std/numeric (inclusive_scan, transform_exclusive_scan): Use std::move to create local copy of the first element. * testsuite/26_numerics/pstl/numeric_ops/108236.cc: Move test using move-only type to ... * testsuite/26_numerics/pstl/numeric_ops/move_only.cc: New test. |

libstdc++: Fix parallel std::exclusive_scan [PR108236]
The standard says that std::exclusive_scan can be used to work in place, i.e. where the output range is the same as the input range. This means that the first sum cannot be written to the output until after reading the first input value, otherwise we'll already have overwritten the first input value. While writing a new testcase I also realised that the serial version of std::exclusive_scan uses copy construction for the accumulator variable, but the standard only requires Cpp17MoveConstructible. We also require move assignable, which is missing from the standard's requirements, but we should at least use move construction not copy construction. A similar problem exists for some other new C++17 numeric algos, but I'll fix the others in a subsequent commit. libstdc++-v3/ChangeLog: PR libstdc++/108236 * include/pstl/glue_numeric_impl.h (exclusive_scan): Pass __init as rvalue. * include/pstl/numeric_impl.h (__brick_transform_scan): Do not write through __result until after reading through __first.

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++: 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. Test internal macros instead of standard macros. * include/bits/alloc_traits.h: Likewise. * include/bits/allocator.h: Likewise. * include/bits/atomic_base.h: Likewise. * include/bits/atomic_timed_wait.h: Likewise. * include/bits/atomic_wait.h: Likewise. * include/bits/basic_string.h: Likewise. * include/bits/basic_string.tcc: Likewise. * include/bits/char_traits.h: Likewise. * include/bits/chrono.h: Likewise. * include/bits/cow_string.h: Likewise. * include/bits/forward_list.h: Likewise. * include/bits/hashtable.h: Likewise. * include/bits/ios_base.h: Likewise. * include/bits/memory_resource.h: Likewise. * include/bits/move.h: Likewise. * include/bits/move_only_function.h: Likewise. * include/bits/node_handle.h: Likewise. * include/bits/ptr_traits.h: Likewise. * include/bits/range_access.h: Likewise. * include/bits/ranges_algo.h: Likewise. * include/bits/ranges_cmp.h: Likewise. * include/bits/ranges_util.h: Likewise. * include/bits/semaphore_base.h: Likewise. * include/bits/shared_ptr.h: Likewise. * include/bits/shared_ptr_atomic.h: Likewise. * include/bits/shared_ptr_base.h: Likewise. * include/bits/stl_algo.h: Likewise. * include/bits/stl_algobase.h: Likewise. * include/bits/stl_function.h: Likewise. * include/bits/stl_iterator.h: Likewise. * include/bits/stl_list.h: Likewise. * include/bits/stl_map.h: Likewise. * include/bits/stl_pair.h: Likewise. * include/bits/stl_queue.h: Likewise. * include/bits/stl_stack.h: Likewise. * include/bits/stl_tree.h: Likewise. * include/bits/stl_uninitialized.h: Likewise. * include/bits/stl_vector.h: Likewise. * include/bits/unique_ptr.h: Likewise. * include/bits/unordered_map.h: Likewise. * include/bits/uses_allocator_args.h: Likewise. * include/bits/utility.h: Likewise. * include/bits/erase_if.h: Add comment. * include/std/algorithm: Define standard feature test macros here. * include/std/atomic: Likewise. * include/std/array: Likewise. * include/std/chrono: Likewise. * include/std/condition_variable: Likewise. * include/std/deque: Likewise. * include/std/format: Likewise. * include/std/functional: Likewise. * include/std/forward_list: Likewise. * include/std/ios: Likewise. * include/std/iterator: Likewise. * include/std/list: Likewise. * include/std/map: Likewise. * include/std/memory: Likewise. * include/std/numeric: Likewise. * include/std/queue: Likewise. * include/std/ranges: Likewise. * include/std/regex: Likewise. * include/std/set: Likewise. * include/std/stack: Likewise. * include/std/stop_token: Likewise. * include/std/string: Likewise. * include/std/string_view: * include/std/tuple: Likewise. * include/std/unordered_map: * include/std/unordered_set: * include/std/utility: Likewise. * include/std/vector: Likewise. * include/std/scoped_allocator: Query internal macros instead of standard macros. |

libstdc++: Make std::lcm and std::gcd detect overflow [PR105844]
When I fixed PR libstdc++/92978 I introduced a regression whereby std::lcm(INT_MIN, 1) and std::lcm(50000, 49999) would no longer produce errors during constant evaluation. Those calls are undefined, because they violate the preconditions that |m| and the result can be represented in the return type (which is int in both those cases). The regression occurred because __absu<unsigned>(INT_MIN) is well-formed, due to the explicit casts to unsigned in that new helper function, and the out-of-range multiplication is well-formed, because unsigned arithmetic wraps instead of overflowing. To fix 92978 I made std::gcm and std::lcm calculate |m| and |n| immediately, yielding a common unsigned type that was used to calculate the result. That was partly correct, but there's no need to use an unsigned type. Doing so only suppresses the overflow errors so the compiler can't detect them. This change replaces __absu with __abs_r that returns the common type (not its corresponding unsigned type). This way we can detect overflow in __abs_r when required, while still supporting the most-negative value when it can be represented in the result type. To detect LCM results that are out of range of the result type we still need explicit checks, because neither constant evaluation nor UBsan will complain about unsigned wrapping for cases such as std::lcm(500000u, 499999u). We can detect those overflows efficiently by using __builtin_mul_overflow and asserting. libstdc++-v3/ChangeLog: PR libstdc++/105844 * include/experimental/numeric (experimental::gcd): Simplify assertions. Use __abs_r instead of __absu. (experimental::lcm): Likewise.

libstdc++: Optimise GCD algorithms
The current std::gcd and std::chrono::duration::_S_gcd algorithms are both recursive. This is potentially expensive to evaluate in constant expressions, because each level of recursion makes a new copy of the function to evaluate. The maximum number of steps is bounded (proportional to the number of decimal digits in the smaller value) and so unlikely to exceed the limit for constexpr nesting, but the memory usage is still suboptimal. By using an iterative algorithm we avoid that compile-time cost. Because looping in constexpr functions is not allowed until C++14, we need to keep the recursive implementation in duration::_S_gcd for C++11 mode. For std::gcd we can also optimise runtime performance by using the binary GCD algorithm. libstdc++-v3/ChangeLog: * include/std/chrono (duration::_S_gcd): Use iterative algorithm for C++14 and later. * include/std/numeric (__detail::__gcd): Replace recursive Euclidean algorithm with iterative version of binary GCD algorithm. * testsuite/26_numerics/gcd/1.cc: Test additional inputs. * testsuite/26_numerics/gcd/gcd_neg.cc: Adjust dg-error lines. * testsuite/26_numerics/lcm/lcm_neg.cc: Likewise. * testsuite/experimental/numeric/gcd.cc: Test additional inputs. * testsuite/26_numerics/gcd/2.cc: New test. |

libstdc++: Fix std::gcd and std::lcm for unsigned integers [PR 92978]
This fixes a bug with mixed signed and unsigned types, where converting a negative value to the unsigned result type alters the value. The solution is to obtain the absolute values of the arguments immediately and to perform the actual GCD or LCM algorithm on two arguments of the same type. In order to operate on the most negative number without overflow when taking its absolute, use an unsigned type for the result of the abs operation. For example, -INT_MIN will overflow, but -(unsigned)INT_MIN is (unsigned)INT_MAX+1U which is the correct value. libstdc++-v3/ChangeLog: PR libstdc++/92978 * include/std/numeric (__abs_integral): Replace with ...
