1 | # In order to work around the very problems that force us to now generally |
| 2 | # create a libgcc.so, glibc reexported a number of routines from libgcc.a. | |
| 3 | # By now choosing the same version tags for these specific routines, we | |
| 4 | # maintain enough binary compatibility to allow future versions of glibc | |
| 5 | # to defer implementation of these routines to libgcc.so via DT_AUXILIARY. | |
