Bug #: 55039
Summary: std::addressof vs. constexpr
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
If std::addressof can be made constexpr, then the iterator member functions of
std::array should be able to be made constexpr as well (begin/end, etc.)
As it stands, std::addressof calls into std::__addressof, which has a
reinterpret_cast, killing constexpr.
If some variation of
http://gcc.gnu.org/onlinedocs/gcc/Return-Address.html
could be extended to support this, then the new intrinsic could be used to
implement std::addressof.
