Jonathan Wakely c4baeaecbb libstdc++: Implement C++26 native handles for file streams (P1759R6) ... The new __basic_file::native_handle() function can be added for C++11 and above, because the names "native_handle" and "native_handle_type" are already reserved since C++11. Exporting those symbols from the shared library does no harm, even if the feature gets dropped before the C++23 standard is final. The new member functions of std::fstream etc. are only declared for C++26 and so are not instantiated in src/c++11/fstream-inst.cc. Declare them with the always_inline attribute so that no symbol definitions are needed in the library (we can change this later when C++26 support is less experimental). libstdc++-v3/ChangeLog: * acinclude.m4 (GLIBCXX_CHECK_FILEBUF_NATIVE_HANDLES): New macro. * config.h.in: Regenerate. * config/abi/pre/gnu.ver (GLIBCXX_3.4.32): Export new basic_filebuf members. * config/io/basic_file_stdio.cc (__basic_file::native_handle): Define new function. * config/io/basic_file_stdio.h (__basic_file::native_handle): Declare new function. * configure: Regenerate. * configure.ac: Use GLIBCXX_CHECK_FILEBUF_NATIVE_HANDLES. * include/bits/version.def (fstream_native_handles): New macro. * include/bits/version.h: Regenerate. * include/std/fstream (basic_filebuf::native_handle) (basic_fstream::native_handle, basic_ifstream::native_handle) (basic_ofstream::native_handle): New functions. * src/c++11/Makefile.am: Move compilation of basic_file.cc, locale_init.cc and localename.cc to here. * src/c++11/Makefile.in: Regenerate. * src/c++98/locale_init.cc: Moved to... * src/c++11/locale_init.cc: ...here. * src/c++98/localename.cc: Moved to... * src/c++11/localename.cc: ...here. * src/c++98/Makefile.am: Remove basic_file.cc, locale_init.cc and localename.cc from here. * src/c++98/Makefile.in: Regenerate. * testsuite/27_io/basic_filebuf/native_handle/version.cc: New test. * testsuite/27_io/basic_fstream/native_handle/char/1.cc: New test. * testsuite/27_io/basic_fstream/native_handle/wchar_t/1.cc: New test. * testsuite/27_io/basic_ifstream/native_handle/char/1.cc: New test. * testsuite/27_io/basic_ifstream/native_handle/wchar_t/1.cc: New test. * testsuite/27_io/basic_ofstream/native_handle/char/1.cc: New test. * testsuite/27_io/basic_ofstream/native_handle/wchar_t/1.cc: New test.		2023-09-15 21:57:41 +01:00
