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.
