See all- Simplify all libc++ containers without breaking the ABI, with Nikolas Klauserechtzeit.dev Office, Berlin
In our June meetup Nikolas Klauser presents his work on libc++ and how it allowed him to simplify all libc++ containers without breaking the ABI.
In LLVM 20, libc++ replaced __compressed_pair with [[no_unique_address]]. __compressed_pair has been used in many containers, as well as unique_ptr and shared_ptr. Removing __compressed_pair has significantly simplified the library and reduced the size of chromium's debug builds by about 5%. I will talk about why keeping the ABI stable is important, what to look out for when modifying ABI-sensitive code, and how I managed to remove __compressed_pair from libc++.
Small snacks and drinks will be available. There is always space for outside topics and discussions. If you have specific questions, please bring them. Looking forward to meeting everyone again!
