Remove the explicit dg-do directive, so that the default is honored, and the test is run if vector support is found, and only compiled otherwise. for libstdc++-v3/ChangeLog PR libstdc++/115454 * testsuite/experimental/simd/pr115454_find_last_set.cc: Defer to check_vect_support_and_set_flags's default dg-do action.
