| 8 | |
| 9 | This directory contains the serialized ABI definitions for a typical build of |
| 10 | the liburcu libraries. This information is extracted using |
| 11 | [libabigail](https://sourceware.org/libabigail/). |
| 12 | |
| 13 | The artefacts used to generate these were built with **CFLAGS="-O0 -ggdb"** on |
| 14 | an Ubuntu 18.04 x86_64 system. |
| 15 | |
| 16 | You can compare the serialized ABI with a shared object to check for breaking |
| 17 | changes. For example, here we compare an in-tree built version of |
| 18 | **liburcu-memb.so** with the serialized ABI of stable-0.13 : |
