This adds the missing C++20 features to <chrono>. I've implemented my proposed resolutions to LWG issues 3960, 3961, and 3962. There are some unimplemented flags such as %OI which I think are not implementable in general. It might be possible to use na_llanginfo with ALT_DIGITS, but that isn't available on all targets. I intend to file another LWG issue about that. libstdc++-v3/ChangeLog: PR libstdc++/104167 * include/bits/chrono_io.h (operator|=, operator|): Add noexcept to _ChronoParts operators. (from_stream, parse): Define new functions. (__detail::_Parse, __detail::_Parser): New class templates. * include/std/chrono (__cpp_lib_chrono): Define to 201907L for C++20. * include/std/version (__cpp_lib_chrono): Likewise. * testsuite/20_util/duration/arithmetic/constexpr_c++17.cc: Adjust expected value of feature test macro. * testsuite/20_util/duration/io.cc: Test parsing. * testsuite/std/time/clock/file/io.cc: Likewise. * testsuite/std/time/clock/gps/io.cc: Likewise. * testsuite/std/time/clock/system/io.cc: Likewise. * testsuite/std/time/clock/tai/io.cc: Likewise. * testsuite/std/time/clock/utc/io.cc: Likewise. * testsuite/std/time/day/io.cc: Likewise. * testsuite/std/time/month/io.cc: Likewise. * testsuite/std/time/month_day/io.cc: Likewise. * testsuite/std/time/weekday/io.cc: Likewise. * testsuite/std/time/year/io.cc: Likewise. * testsuite/std/time/year_month/io.cc: Likewise. * testsuite/std/time/year_month_day/io.cc: Likewise. * testsuite/std/time/syn_c++20.cc: Check value of macro and for the existence of parse and from_stream in namespace chrono. * testsuite/std/time/clock/local/io.cc: New test. * testsuite/std/time/parse.cc: New test. |
