This directory contains the serialized ABI definitions for a typical build of
the lttng-ust librairies. This information is extracted using libabigail
(https://sourceware.org/libabigail/).

The artefacts used to generate these were built with CFLAGS="-O0 -ggdb" and all
optional configure switches enabled.

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
liblttng-ust.so with the serialized ABI of stable-2.13 :

  abidiff \
    extras/abi/2.13/x86_64-pc-linux-gnu/liblttng-ust.so.1.xml \
    src/lib/lttng-ust/.libs/liblttng-ust.so
