Bug ID: 60326
Summary: Incorrect type from std::make_unsigned<wchar_t>
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: kristian.spangsege at gmail dot com
The `std::make_signed` and `std::make_unsigned` templates appear to be
incorrectly implemented in GCC 4.8.1.
In particular, both `std::make_signed<wchar_t>::type` and
`std::make_unsigned<wchar_t>::type` produces the type `wchar_t`.
I don't claim to know what the right behaviour is, but it seems wrong, what is
currently done.
Clang 3.4 with `libc++` does this on x86_64:
std::make_unsigned<wchar_t>::type --> int
std::make_unsigned<wchar_t>::type --> unsigned
which seems more reasonable.
The most relevant section in the C++11 standard appears to be 20.9.7.3
[meta.trans.sign].
