Author: dim Date: Wed Feb 22 18:44:57 2017 New Revision: 314104 URL: https://svnweb.freebsd.org/changeset/base/314104 Log: 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. Helpful hints: emaste MFC after: 2 weeks X-MFC-With: r314061 Modified: head/lib/libcxxrt/Version.map Modified: head/lib/libcxxrt/Version.map ============================================================================== --- head/lib/libcxxrt/Version.map Wed Feb 22 17:57:24 2017 (r314103) +++ head/lib/libcxxrt/Version.map Wed Feb 22 18:44:57 2017 (r314104) @@ -255,12 +255,14 @@ CXXABI_1.3.1 { } CXXABI_1.3; CXXABI_1.3.5 { - "typeinfo for __int128 const*"; - "typeinfo for __int128"; - "typeinfo for __int128*"; - "typeinfo for unsigned __int128 const*"; - "typeinfo for unsigned __int128"; - "typeinfo for unsigned __int128*"; + extern "C++" { + "typeinfo for __int128 const*"; + "typeinfo for __int128"; + "typeinfo for __int128*"; + "typeinfo for unsigned __int128 const*"; + "typeinfo for unsigned __int128"; + "typeinfo for unsigned __int128*"; + }; } CXXABI_1.3.1; CXXABI_1.3.6 { @@ -268,12 +270,14 @@ CXXABI_1.3.6 { } CXXABI_1.3.5; CXXABI_1.3.9 { - "typeinfo name for __int128 const*"; - "typeinfo name for __int128"; - "typeinfo name for __int128*"; - "typeinfo name for unsigned __int128 const*"; - "typeinfo name for unsigned __int128"; - "typeinfo name for unsigned __int128*"; + extern "C++" { + "typeinfo name for __int128 const*"; + "typeinfo name for __int128"; + "typeinfo name for __int128*"; + "typeinfo name for unsigned __int128 const*"; + "typeinfo name for unsigned __int128"; + "typeinfo name for unsigned __int128*"; + }; } CXXABI_1.3.6; CXXRT_1.0 {
