Jonathan Wakely 5840e3b8ff PR libstdc++/84928 use std::move in <numeric> algorithms ... P0616R0 altered the effects of the <numeric> algorithms to use std::move on the accumulator values (resolving LWG 2055). This implements the change for C++2a, but retains the previous behaviour for older standards. * include/bits/stl_numeric.h (_GLIBCXX_MOVE_IF_20): Define macro to conditionally move, according to __cplusplus value. (accumulate, inner_product, partial_sum, adjacent_difference): Use _GLIBCXX_MOVE_IF_20. * testsuite/26_numerics/accumulate/lwg2055.cc: New test. * testsuite/26_numerics/adjacent_difference/lwg2055.cc: New test. * testsuite/26_numerics/inner_product/lwg2055.cc: New test. * testsuite/26_numerics/partial_sum/lwg2055.cc: New test.
