commit 78ea1de07c316c71d0a5ad9fb2a9d1e7f31bea65
Author: Corentin Gay <gay@adacore.com>
Date:   Thu Dec 31 21:37:28 2020 -0300

    Add dg-require-wchars to libstdc++ testsuite
    
    Some tests uses structures from the libstdc++ that are present only if
    the target has a wchar.h header.  However, those tests do not check
    that the target supports those constructs before executing the tests.
    
    The function dg-require-wchars checks that "_GLIBCXX_USE_WCHAR_T" is
    defined by the configure of the libstdc++.  If it is not the case, the
    test is not executed.
    
    
    for  libstdc++-v3/ChangeLog
    
            * testsuite/lib/dg-options.exp: Add dg-require-wchars
            function.
            * testsuite/lib/libstdc++.exp: Add check_v3_target_wchars
            function.
            * testsuite/22_locale/codecvt/codecvt_utf16/79980.cc: Add
            requirement.
            * testsuite/22_locale/codecvt/codecvt_utf16/misaligned.cc:
            Likewise.

commit 58cf5285801d7943d56c90f2e9116641f9f0784a
Author: Corentin Gay <gay@adacore.com>
Date:   Thu Dec 24 22:43:03 2020 -0300

    Add dg-require-wchars to libstdc++ testsuite
    
    Some tests uses structures from the libstdc++ that are present only if
    the target has a wchar.h header.  However, those tests do not check
    that the target supports those constructs before executing the tests.
    
    The function dg-require-wchars checks that "_GLIBCXX_USE_WCHAR_T" is
    defined by the configure of the libstdc++.  If it is not the case, the
    test is not executed.
    
    
    for  libstdc++-v3/ChangeLog
    
            * testsuite/lib/dg-options.exp: Add dg-require-wchars
            function.
            * testsuite/lib/libstdc++.exp: Add check_v3_target_wchars
            function.
            * testsuite/22_locale/codecvt/codecvt_utf16/79980.cc: Add
            requirement.
            * testsuite/22_locale/codecvt/codecvt_utf16/misaligned.cc:
            Likewise.

commit 3cf14e818ebcce936aafd149c57252496dc0737e
Author: Corentin Gay <gay@adacore.com>
Date:   Fri Dec 18 11:39:24 2020 -0300

    Add dg-require-wchars to libstdc++ testsuite
    
    Some tests uses structures from the libstdc++ that are present only if
    the target has a wchar.h header.  However, those tests do not check
    that the target supports those constructs before executing the tests.
    
    The function dg-require-wchars checks that "_GLIBCXX_USE_WCHAR_T" is
    defined by the configure of the libstdc++.  If it is not the case, the
    test is not executed.
    
    
    for  libstdc++-v3/ChangeLog
    
            * testsuite/lib/dg-options.exp: Add dg-require-wchars
            function.
            * testsuite/lib/libstdc++.exp: Add check_v3_target_wchars
            function.
            * testsuite/22_locale/codecvt/codecvt_utf16/79980.cc: Add
            requirement.
            * testsuite/22_locale/codecvt/codecvt_utf16/misaligned.cc:
            Likewise.
            * testsuite/22_locale/codecvt/codecvt_utf8/79980.cc: Likewise.
            * testsuite/22_locale/codecvt/codecvt_utf8_utf16/79511.cc:
