Bug ID: 78273
Summary: The transparent version of {map,set}::count should
call _M_count_tr
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: rs2740 at gmail dot com
Target Milestone: ---
They are currently
> template<typename _Kt>
> auto
> count(const _Kt& __x) const
> -> decltype(_M_t._M_count_tr(__x))
> { return _M_t._M_find_tr(__x) == _M_t.end() ? 0 : 1; }
but there is no requirement that at most one key in the container compare
equivalent to the heterogeneous key; the only requirement is that the keys of
the elements in the container be suitably partitioned with respect to the
heterogeneous key. Thus, they should simply return _M_t._M_count_tr(__x);.
