--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Gabriel Ibarra from comment #5) > 1) When you say "it can't be applied until after GCC 6", you mean that my > changes won't be commited until then? If you commit this now, how would you > handle me using 4.23 as a version number? We're not going to commit anything now. We're preparing for the GCC 6 release and not adding new features. > 2) If you commit this now, is there any way to make the unit test that I > added run only for GLIBCXX_3.4.23? No, but we're not committing it now so it doesn't matter. > 3) And finally, how should I deal with the sized delete? Since it depends on > the __cpp_sized_deallocation macro, should I add a test that also depends on > this macro? Yes, that seems sensible.
