I'd like to present a new project called "ABI Navigator" to search for binary symbols (functions, methods, global data, etc.) in libc++ and other open-source libraries: https://abi-laboratory.pro/index.php?view=navigator
The project allows to find out in which versions of the library some symbol is defined, added, removed or changed. The project is based on the ABI report for libc++: https://abi-laboratory.pro/tracker/timeline/libcxx/
Example for symbol _ZdlPvm: https://abi-laboratory.pro/index.php?view=navigator&selected=_ZdlPvm
The project aims to help library users and maintainers to resolve issues with missed symbols and navigate through the ABI reports.
Have you ever encountered the "undefined reference" error or want to know whether the symbol is _stable_ enough to import by your code? Try to find it in the ABI Navigator!
