--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> --- Just to add a compile-only "override" would be useful to do bare testing of cross compilers where no (or an incomplete) runtime is available to reduce the amount of noise produced (you still get complaints about missing headers of course). Not sure if easily doable across all testsuites though. I agree not so useful for libstdc++
