| 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. |
