>
> PR libstdc++/79980
> * include/bits/locale_conv.h (__do_str_codecvt): Set __count on
> error path.
> * src/c++11/codecvt.cc (operator&=, operator|=, operator~): Overloads
> for manipulating codecvt_mode values.
> (read_utf16_bom): Compare input to BOM constants instead of integral
> constants that depend on endianness. Take mode parameter by
> reference and adjust it, to distinguish between no BOM present and
> UTF-16BE BOM present.
> (ucs4_in, ucs2_span, ucs4_span): Adjust calls to read_utf16_bom.
> (surrogates): New enumeration type.
> (utf16_in, utf16_out): Add surrogates parameter to choose between
> UTF-16 and UCS2 behaviour.
> (utf16_span, ucs2_span): Use std::min not std::max.
> (ucs2_out): Use std::min not std::max. Disallow surrogate pairs.
> (ucs2_in): Likewise. Adjust calls to read_utf16_bom.
> * testsuite/22_locale/codecvt/codecvt_utf16/79980.cc: New test.
> * testsuite/22_locale/codecvt/codecvt_utf8/79980.cc: New test.

Please revert this change. It breaks bootstrap with clang on FreeBSD.
