In r15-8980-gf4b6acfc36fb1f I introduced a new function object for finding the smaller of two distances. In bugzilla Hewill Kang pointed out that we still need to explicitly convert the result back to the right difference type, because the result might be an integer-like class type that doesn't convert to an integral type explicitly. Rather than doing that conversion in the __mindist function object, I think it's simpler to remove it again and just do a comparison and assignment. We always want the result to have a specific type, so we can just check if the value of the other type is smaller, and then convert that to the other type if so. libstdc++-v3/ChangeLog: PR libstdc++/101587 * include/bits/ranges_uninitialized.h (__detail::__mindist): Remove. (ranges::uninitialized_copy, ranges::uninitialized_copy_n) (ranges::uninitialized_move, ranges::uninitialized_move_n): Use comparison and assignment instead of __mindist. * testsuite/20_util/specialized_algorithms/uninitialized_copy/constrained.cc: Check with ranges that use integer-like class type for difference type. * testsuite/20_util/specialized_algorithms/uninitialized_move/constrained.cc: Likewise.
