Bug #: 54237 Summary: [C++11] Make more tuple-related functions constexpr Classification: Unclassified Product: gcc Version: 4.8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: zeratul...@hotmail.com Many tuple-related functions are already constexpr (e.g. tuple constructors, get(), tuple_cat(), make_tuple()). I think more of them can be made constexpr, in particular tie() and the comparison operators (operator< and friends).
