commit fa404848f2a2753f2b1a52188b5ec30a6dd9949f
Author: Jonathan Wakely <jwakely@redhat.com>
Date: Fri Oct 31 20:02:13 2014 +0000
Make std::vector<bool> meet C++11 allocator requirements.
* include/bits/stl_bvector.h (_Bvector_base): Use allocator_traits.
(_Bvector_base::_Bvector_impl): Use allocator's pointer type.
(_Bvector_base::_M_end_addr()): Convert to raw pointer.
(vector<bool>): Use allocator_traits and _M_end_addr. Add allocator
extended constructors.
* include/bits/vector.tcc (vector<bool>): Use allocator_traits and
_M_end_addr.
* testsuite/23_containers/vector/bool/allocator/copy.cc: New.
* testsuite/23_containers/vector/bool/allocator/minimal.cc: New.
* testsuite/23_containers/vector/bool/allocator/noexcept.cc: New.
* testsuite/23_containers/vector/bool/allocator/copy_assign.cc: New.
* testsuite/23_containers/vector/bool/allocator/move.cc: New.
* testsuite/23_containers/vector/bool/allocator/swap.cc: New.
* testsuite/23_containers/vector/bool/allocator/ext_ptr.cc: New.
* testsuite/23_containers/vector/bool/allocator/move_assign.cc: New.
