Jonathan Wakely b96b554592 libstdc++: Add Filesystem TS and std::stacktrace symbols to libstdc++exp.a ... This consolidates the three static archives for extensions into one, so that -lstdc++exp can be used to provide the definitions of all unstable library features. The libstdc++_libbacktrace.a archive is now just a "noinst" convenience library that is only used during the build, not installed. Its contents are added to libstdc++exp.a, along with the new non-inline definitions of std::stacktrace symbols. The libstdc++fs.a archive is still installed, but its contents are duplicated in libstdc++exp.a now. This means -lstdc++exp can be used instead of -lstdc++fs. For targets using the GNU linker we should consider replacing libstdc++fs.a with a linker script that does INPUT(libstdc++exp.a). The tests for <experimental/filesystem> could be changed to use -lstdc++exp instead of -lstdc++fs, which would allow removing src/filesystem/.libs from the LDFLAGS in scripts/testsuite_flags.in, but that can be done at a later date. libstdc++-v3/ChangeLog: * acinclude.m4 (GLIBCXX_CONFIGURE): Add c++23 directory. * configure: Regenerate. * doc/html/manual/*: Regenerate. * doc/xml/manual/using.xml: Update documentation on linking. * include/std/stacktrace: Remove declarations of libbacktrace APIs. (stacktrace_entry::_S_err_handler, stacktrace_entry::_S_init): Remove. (stacktrace_entry::_Info): New class. (stacktrace_entry::_M_get_info): Use _Info. (__stacktrace_impl): New class. (basic_stacktrace): Derive from __stacktrace_impl. (basic_stacktrace::current): Use __stacktrace_impl::_S_current. * scripts/testsuite_flags.in: Adjust LDFLAGS to find libstdc++exp instead of libstdc++_libbacktrace. * src/Makefile.am (SUBDIRS): Add c++23 directory. * src/Makefile.in: Regenerate. * src/c++20/Makefile.am: Fix comment. * src/c++20/Makefile.in: Regenerate. * src/c++23/Makefile.am: New file. * src/c++23/Makefile.in: New file. * src/c++23/stacktrace.cc: New file with definitions of stacktrace_entry::_Info and __stacktrace_impl members. * src/experimental/Makefile.am: Use LIBADD to include other libraries. * src/experimental/Makefile.in: Regenerate. * src/libbacktrace/Makefile.am: Use noinst_LTLIBRARIES. * src/libbacktrace/Makefile.in: Regenerate. * testsuite/19_diagnostics/stacktrace/current.cc: Adjust dg-options to use -lstdc++exp. * testsuite/19_diagnostics/stacktrace/entry.cc: Likewise. * testsuite/19_diagnostics/stacktrace/stacktrace.cc: Likewise. * testsuite/23_containers/vector/debug/assign4_backtrace_neg.cc: Likewise.		2023-09-08 18:04:12 +01:00
