This directory contains the serialized ABI definitions for a typical build of the liburcu libraries. This information is extracted using libabigail (https://sourceware.org/libabigail/). The artefacts used to generate these were built with CFLAGS="-O0 -ggdb". You can compare the serialized ABI with a shared object to check for breaking changes. For example, here we compare an in-tree built version of liburcu-memb.so with the serialized ABI of stable-0.13 : abidiff \ extras/abi/0.13/x86_64-pc-linux-gnu/liburcu-memb.so.7.xml \ src/.libs/liburcu-memb.so
