  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.
