  19 # In order to work around the very problems that force us to now generally
  20 # create a libgcc.so, glibc reexported a number of routines from libgcc.a.
  21 # By now choosing the same version tags for these specific routines, we
  22 # maintain enough binary compatibility to allow future versions of glibc
  23 # to defer implementation of these routines to libgcc.so via DT_AUXILIARY.
  24
  25 # Note that we cannot use the default libgcc-glibc.ver file on s390x,
  26 # because GLIBC_2.0 does not exist on this architecture, as the first
  27 # ever glibc release on the platform was GLIBC_2.2.
