| # maintain enough binary compatibility to allow future versions of glibc |
| # to defer implementation of these routines to libgcc.so via DT_AUXILIARY. |

| # Note that we cannot use the default libgcc-glibc.ver file on s390x, |
| # because GLIBC_2.0 does not exist on this architecture, as the first |
| # ever glibc release on the platform was GLIBC_2.2. |
