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 : | |
