Hi
I am not clear about current stage so I am proposing this trivial patch
to find out if we are back in stage 1.
This patch extend the overload so that it is used even when
_GLIBCXX_DEBUG mode is activated.
* include/bits/stl_algobase.h (struct _Bit_iterator): New
declaration.
(std::__fill_a1(_Bit_iterator, _Bit_iterator, const
bool&)): Likewise.
* include/bits/stl_bvector.h (__fill_bvector): Move outside
_GLIBCXX_STD_C namespace.
(fill(_Bit_iterator, _Bit_iterator, const bool&)): Likewise
and rename
into...
(__fill_a1): ...this.
* testsuite/25_algorithms/fill/bvector/1.cc: New.
Tested under Linux x86_64 normal and debug modes.
Ok to commit ?
François
