2008-11-01 Jonathan Wakely <jwakely.gcc@gmail.com> * include/bits/shared_ptr.h: Update comparisons to match WP. (_Sp_counted_ptr): Make copy and assignment members deleted. (_Sp_counted_deleter): Remove private copy and assignment members. (__shared_count::_M_less,__weak_count::_M_less,operator<): Replace friend operator< with overloaded _M_less member functions to allow comparison with either shared_count or weak_count. (__shared_ptr::_M_less,__weak_ptr::_M_less): Replace with... (__shared_ptr::owner_before,__weak_ptr::owner_before): New overloads for ownership-based ordering. (operator<(__shared_ptr,__shared_ptr)): Compare stored pointers, make non-friend. (operator==(__shared_ptr,__shared_ptr)): Make non-friend. (operator!=(__shared_ptr,__shared_ptr)): Likewise. (less<__shared_ptr<>>,less<shared_ptr<>>,_Sp_less): Explicitly call pointer specialization. (__weak_ptr::operator<,weak_ptr::operator<=,weak_ptr::operator>, weak_ptr::operator>=): Remove operator< and delete all comparisons. (_Sp_owner_less,owner_less): Predicate for ownership-based ordering. (operator<(shared_ptr,shared_ptr): Overload for derived shared_ptr. (operator==(shared_ptr,shared_ptr): Likewise. (operator!=(shared_ptr,shared_ptr): Likewise. (swap(shared_ptr,shared_ptr)): Fix parameter types. (swap(weak_ptr,weak_ptr)): Add missing overload. * testsuite/20_util/owner_less/cmp.cc: New. * testsuite/20_util/shared_ptr/comparison/cmp.cc: Test other ops. * testsuite/20_util/shared_ptr/comparison/less.cc: New. * testsuite/20_util/shared_ptr/observers/owner_before.cc: New. * testsuite/20_util/weak_ptr/observers/owner_before.cc: New. * testsuite/20_util/weak_ptr/comparison/cmp_neg.cc: New.
