This directory contains abi lists representing the symbols exported by the libc++ library. The lists are generated using libcxx/utils/generate_abi_list.py.

Every time a symbol is added or removed from the libc++ library, each of the lists MUST be updated to reflect the changes. This can be done by using the generate-cxx-abilist CMake target.

We do not keep an up-to-date ABI list for all the build configurations of libc++. Currently, only the default configuration on MacOS and Linux are supported.
