# In order to work around the very problems that force us to now generally
# create a libgcc.so, glibc reexported a number of routines from libgcc.a.
# By now choosing the same version tags for these specific routines, we
# 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.
