Summary: Ensure we re-export __cxa_throw_bad_array_new_length and __cxa_uncaught_exceptions from libc++, since they are now provided by libc++abi. Doing this allows us to stop linking explicitly against libc++abi in the libc++abi tests, since libc++ re-exports all the necessary symbols. However, there is one caveat to that. We don't want libc++ to re-export __cxa_uncaught_exception (the singular form), since it's only provided for backwards compatibility. Hence, for the single test where we check this backwards compatibility, we explicitly link against libc++abi.

This directory contains abi lists representing the symbols exported by the libc++ library. The lists are generated using sym_extract.py. Every time a symbol is added or removed from the libc++ library each of the lists *MUST* be updated to reflect the changes. TODO Add more documentation about generating and using the lists. TODO Add more documentation about the build configuration the lists are generated against.
