I believe lld's behaviour is correct. Contemporary versions of ld.bfd also behave as lld does, so move the mangled symbols out of the `extern "C++"` block.

Put these into the same CXXABI verions as recent libstdc++. Note that __int128 types are only available on arches where long long is 128 bit wide. Noticed by: harti MFC r314104: Surround any unmangled C++ names in libcxxrt's version map with 'extern "C++"', otherwise ld refuses to make the symbols global in the final library. This causes the __int128-related symbols to go missing when the library is stripped during installation.

It appears that a number of duplicate mangled symbols were added due to a cut and paste error. Switch the second instances to _ZTS*, typeinfo name for *. Found by lld, which produces an error or warning for duplicate symbols.

More information the need of these flags can be found at https://gcc.gnu.org/ml/gcc/2016-03/msg00219.html This also reverts r300873.

Also change one _Static_assert (which is really C11) back into static_assert, like upstream. This should help when compiling libcxxrt with newer versions of gcc, which refuse to recognize any form of static assertions, if not compiling for C++11 or higher. While here, add -nostdinc++ to CFLAGS, to prevent picking up any C++ headers outside the source tree. 2016-03-02T16:14:46Z Glen Barber gjb@FreeBSD.org 2016-03-02T16:14:46Z urn:sha1:52259a98adba7622f236db46a330e61df0c84fb1 Sponsored by: The FreeBSD Foundation
