To: libstdc++, gcc-patches
Tested x86_64-linux (glibc 2.33) and powerpc64le-linux (glibc 2.17).
Pushed to trunk.
This checks whether the locale data for en_HK includes %p and adjusts
the string being tested accordingly. To account for Jakub's fix to make
%I parse "12" as 0 instead of 12, we need to change the expected value
for the case where the locale format doesn't include %p. Also change the
time from 12:00:00 to 12:02:01 so we can tell if the minutes and seconds
get mixed up.
libstdc++-v3/ChangeLog:
PR libstdc++/103687
* testsuite/22_locale/time_get/get_date/wchar_t/4.cc: Restore
original locale before returning.
* testsuite/22_locale/time_get/get_time/char/2.cc: Check for %p
in locale's T_FMT and adjust accordingly.
* testsuite/22_locale/time_get/get_time/wchar_t/2.cc: Likewise.
