2025-05-06libstdc++: Fix <numeric> parallel algos for move-only values [PR117905]Jonathan Wakely1-3/+3
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.
2025-04-15libstdc++: Do not declare namespace ranges in <numeric> unconditionallyJonathan Wakely1-5/+3
Move namespace ranges inside the feature test macro guard, because 'ranges' is not a reserved name before C++20. libstdc++-v3/ChangeLog: * include/std/numeric (ranges): Only declare namespace for C++23 and later. (ranges::iota_result): Fix indentation. * testsuite/17_intro/names.cc: Check ranges is not used as an identifier before C++20.

2024-12-03libstdc++: Fix parallel std::exclusive_scan [PR108236]Jonathan Wakely1-2/+2
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. Move __init into return value. (__pattern_transform_scan): Pass __init as rvalue. * include/std/numeric (exclusive_scan): Move construct instead of copy constructing. * testsuite/26_numerics/exclusive_scan/2.cc: New test. * testsuite/26_numerics/pstl/numeric_ops/108236.cc: New test.
2024-09-25libstdc++: #ifdef out #pragma GCC system_headerJason Merrill1-0/+2
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

2023-11-16libstdc++: Only declare feature test macros in standard headersJonathan Wakely1-0/+1
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.

2022-06-10libstdc++: Make std::lcm and std::gcd detect overflow [PR105844]Jonathan Wakely1-33/+42
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.

2020-09-03libstdc++: Optimise GCD algorithmsJonathan Wakely1-4/+30
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.

2020-08-28libstdc++: Fix std::gcd and std::lcm for unsigned integers [PR 92978]Jonathan Wakely1-41/+42
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 ...
