This rewrites ranges::minmax and ranges::minmax_element so that it performs at most 3*N/2 many comparisons, as required by the standard. In passing, this also fixes PR100387 by avoiding a premature std::move in ranges::minmax and in std::shift_right. PR libstdc++/100387 libstdc++-v3/ChangeLog: * include/bits/ranges_algo.h (__minmax_fn::operator()): Rewrite to limit comparison complexity to 3*N/2. (__minmax_element_fn::operator()): Likewise. (shift_right): Avoid premature std::move of __result. * testsuite/25_algorithms/minmax/constrained.cc (test04, test05): New tests. * testsuite/25_algorithms/minmax_element/constrained.cc (test02): Likewise. |
