This adds the operator<< overloads and std::formatter specializations required by C++20 so that <chrono> types can be written to ostreams and printed with std::format. libstdc++-v3/ChangeLog: * include/Makefile.am: Add new header. * include/Makefile.in: Regenerate. * include/std/chrono (operator<<): Move to new header. (nonexistent_local_time::_M_make_what_str): Define correctly. (ambiguous_local_time::_M_make_what_str): Likewise. * include/bits/chrono_io.h: New file. * src/c++20/tzdb.cc (operator<<(ostream&, const Rule&)): Use new ostream output for month and weekday types. * testsuite/20_util/duration/io.cc: Test std::format support. * testsuite/std/time/exceptions.cc: Check what() strings. * testsuite/std/time/syn_c++20.cc: Uncomment local_time_format. * testsuite/std/time/time_zone/get_info_local.cc: Enable check for formatted output of local_info objects. * testsuite/std/time/clock/file/io.cc: New test. * testsuite/std/time/clock/gps/io.cc: New test. * testsuite/std/time/clock/system/io.cc: New test. * testsuite/std/time/clock/tai/io.cc: New test. * testsuite/std/time/clock/utc/io.cc: New test. * testsuite/std/time/day/io.cc: New test. * testsuite/std/time/format.cc: New test. * testsuite/std/time/hh_mm_ss/io.cc: New test. * testsuite/std/time/month/io.cc: New test. * testsuite/std/time/weekday/io.cc: New test. * testsuite/std/time/year/io.cc: New test. * testsuite/std/time/year_month_day/io.cc: New test. |
