Jonathan Wakely 1a289fa362 Export explicit instantiations for C++17 members of std::string ... The C++17 standard added some new members to std::basic_string, which were not previously instantiated in the library. This meant that the extern template declarations had to be disabled for C++17 mode. With this patch the new members are instantiated in the library and so the explicit instantiation declarations can be used for C++17. The new members added by C++2a are still not exported, and so the explicit instantiation declarations are still disabled for C++2a. * config/abi/pre/gnu.ver (GLIBCXX_3.4.21): Make patterns less greedy for const member functions of std::basic_string. (GLIBCXX_3.4.26): Export member functions of std::basic_string added in C++17. * include/bits/basic_string.h (basic_string(__sv_wrapper, const A&)): Make non-standard constructor private. [!_GLIBCXX_USE_CXX11_ABI] (basic_string(__sv_wrapper, const A&)): Likewise. * include/bits/basic_string.tcc (std::string, std::wstring): Declare explicit instantiations for C++17 as well as earlier dialects. * src/c++17/Makefile.am: Add new source files. * src/c++17/Makefile.in: Regenerate. * src/c++17/cow-string-inst.cc: New file defining explicit instantiations for basic_string member functions added in C++17. * src/c++17/string-inst.cc: Likewise.
