This incremental patch adds std::time_get %r support (%p was added already in the previous patch). The _M_am_fm_format method previously in the header unfortunately had wrong arguments and so was useless, so the largest complication in this patch is exporting a new symbol in the right symbol version. Tested on x86_64-linux, ok for trunk? 2021-12-10 Jakub Jelinek PR libstdc++/71367 * config/locale/dragonfly/time_members.cc (_M_initialize_timepunct): Initialize "C" _M_am_pm_format to %I:%M:%S %p rather than empty string. * config/locale/gnu/time_members.cc (_M_initialize_timepunct): Likewise. * config/locale/generic/time_members.cc (_M_initialize_timepunct): Likewise. * include/bits/locale_facets_nonio.h (_M_am_pm_format): New method. * include/bits/locale_facets_nonio.tcc (_M_extract_via_format): Handle %r. * config/abi/pre/gnu.ver (GLIBCXX_3.4.30): Export _M_am_pm_format with const _CharT** argument, ensure it isn't exported in GLIBCXX_3.4. * testsuite/22_locale/time_get/get/char/71367.cc: New test. * testsuite/22_locale/time_get/get/wchar_t/71367.cc: New test.
