Since we use C++20 to build the dylib, we can use a lambda to do the first-time initialization instead of emulating std::bind. This should not change the behavior of the code at all, it merely simplifies it. This removes a symbol from the dylib, however that symbol was only ever used inside the dylib so it shouldn't break the ABI for anyone. I confirmed that by searching for that symbol on the ABI boundary of a large number of programs and couldn't find any references to that function.
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.
