invoke.texi ([Wnarrowing]): Update for non-constants in C++11.
2014-08-09 Paolo Carlini <paolo.carlini@oracle.com>
* doc/invoke.texi ([Wnarrowing]): Update for non-constants in C++11.
gcc/cp
2014-08-09 Paolo Carlini <paolo.carlini@oracle.com>
* typeck2.c (check_narrowing): Add tsubst_flags_t parameter, change
return type to bool; in C++11 for constants give errors, not pedwarns.
* cp-tree.h (check_narrowing): Adjust declaration.
* call.c (convert_like_real): Update calls.
* semantics.c (finish_compound_literal): Likewise.
gcc/testsuite
2014-08-09 Paolo Carlini <paolo.carlini@oracle.com>
* g++.dg/cpp0x/Wnarrowing1.C: Adjust for errors.
* g++.dg/cpp0x/enum29.C: Adjust.
/libstdc++-v3
2014-08-09 Paolo Carlini <paolo.carlini@oracle.com>
* include/ext/pod_char_traits.h (char_traits<__gnu_cxx::
character<_Value, _Int, _St> >::eof): Fix vs narrowing conversion.
