Could somebody please check? Yes, this is the right place, though with a few caveats: * We also need to add the typeinfo for __u?int128_t * and __u?int128_t const * * Maybe these should be under the CXXABI_2.0 version, since that is where newer libstdc++ places them * Maybe these should be dependent on whether the architecture supports 128 bit integers at all I need to think a bit on the above, then I'll commit a fix. -Dimitry P.S.: I'm going to ignore libstdc++ in base, since it is obsolete. --Apple-Mail=_E5BA89B5-8489-4A93-86A3-7B7846A3AB0E Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP -----BEGIN PGP SIGNATURE----- iEYEARECAAYFAliseDAACgkQsF6jCi4glqNzhwCeI4ATx4sLJp2cf2Q+E+5HH0oP otYAn3HGOkVXwXQNB6mCdvtcDVW7Qb2W =c6Ll -----END PGP SIGNATURE----- --Apple-Mail=_E5BA89B5-8489-4A93-86A3-7B7846A3AB0E--
