| 7 | This directory contains the serialized ABI definitions for a typical build of |
| 8 | the lttng-ust libraries. This information is extracted using |
| 9 | [libabigail](https://sourceware.org/libabigail/). |
| 10 | |
| 11 | The artefacts used to generate these were built with `CFLAGS="-O0 -ggdb"` and |
| 12 | all optional configure switches enabled. |
| 13 | |
| 14 | You can compare the serialized ABI with a shared object to check for breaking |
| 15 | changes. For example, here we compare an in-tree built version of |
| 16 | `liblttng-ust.so` with the serialized ABI of stable-2.13 : |
