2003-06-24  Paolo Carlini  <pcarlini@unitus.it>
            Nathan C. Myers  <ncm-nospam@cantrip.org>

	* include/std/std_fstream.h (_M_filepos): Remove.
	(_M_reading, _M_writing): New, encode the various I/O modes:
	'read', 'write' and 'uncommitted'.
	(sync): If there is something to flush, do it, then go to
	'uncommitted' mode.
	* include/bits/fstream.tcc (_M_set_buffer): Overhaul to deal
	with three different cases: __off > 0 (upon underflow),
	__off == 0 (upon overflow), __off == -1 (upon open, setbuf,
	seekoff/pos).
	(_M_underflow): Don't call overflow, set _M_reading to true
	on success, tweak.
	(pbackfail): Set _M_reading to true on pback creation, tweak.
	(overflow): Don't seek, deal with overflow in 'uncommitted' mode,
	set _M_writing to true on success, tweak.
	(seekoff): Simplify, set _M_reading, _M_writing to false, call
	_M_set_buffer(-1) ('uncommitted').
	(open, close, setbuf): Set _M_reading, _M_writing to false and
	call _M_set_buffer(-1), tweak.
	(basic_filebuf): Don't set _M_buf_unified.
	(_M_destroy_internal_buffer): Don't call setg and setp.
	* include/ext/stdio_filebuf.h (stdio_filebuf): Use _M_reading,
	_M_writing and _M_set_buffer(-1).
	* include/std/std_streambuf.h (_M_move_out_cur, _M_move_in_cur,
	_M_out_lim, _M_buf_unified): Remove.
	(basic_streambuf): Don't set _M_out_lim and _M_buf_unified.
	(setp): Don't set _M_out_lim.	
	* testsuite/27_io/basic_filebuf/sbumpc/char/1-io.cc: Fix for
	the new logic ('read', 'write' and 'uncommitted' modes): e.g.,
	upon open the mode is 'uncommitted' and therefore the put area
	pointers are null.
	* testsuite/27_io/basic_filebuf/sbumpc/char/1-out.cc: Ditto.
	* testsuite/27_io/basic_filebuf/seekoff/char/3-io.cc: Ditto.

	upon overflow, underflow, uflow, seekoff/pos.
	* include/bits/sstream.tcc (_M_underflow): New, implements
	stringbuf::underflow and uflow.
	(seekoff, seekpos): Tweak, use  _M_update_egptr.
	* include/std/std_sstream.h (str): Rewrote, deal correctly
	with the new logic, in particular, when pptr() > egptr().
	(_M_sync): When __testout && !__testin set all the get area
	pointers to the current string end.
	(_M_update_egptr): New, internal function updating egptr()
	to the actual string end.

2003-06-13  Nathan C. Myers <ncm-nospam@cantrip.org>

	Avoid multi-processor bus contention on increment/decrement-and-
	test of the reference count in the empty-string object, by comparing
        addresses first, and never touching the reference count of the empty-
        string object.
	* include/bits/basic_string.h:
	(_S_empty_rep_storage): Move into basic_string<>::_Rep for use by its
	members.
	(_Rep::_S_empty_rep()): New accessor.
	(_Rep::_M_length, _Rep::_M_capacity, _Rep::_M_references): Move to
	a base class _Rep_base.
	(_Rep::_M_dispose, _Rep::_M_refcopy): Check for the empty string.
	(basic_string()): Change to use _M_refdata() in place of _M_refcopy(),
	since no longer must increment its refcount.
	* include/bits/basic_string.tcc:
	(_Rep::_M_destroy, _M_leak_hard): Check for the empty string and
        return immediately.  The former might be unnecessary.  The latter
        prevents begin() and end() from cloning it unnecessarily.
	(_S_construct(_InIterator, _InIterator, const _Alloc&,
	input_iterator_tag), _S_construct(_InIterator, _InIterator,
	const _Alloc&, forward_iterator_tag), _S_construct(size_type, _CharT,
	const _Alloc&)): Change to use _M_refdata() in place of _M_refcopy().
	(_M_mutate): Check for the empty string and treat it as shared.
        This is necessary here because _M_mutate is sometimes called with
        all-zero arguments; in all other uses of _M_is_shared, the test comes
        out right anyhow.

2003-06-12  Benjamin Kosnik  <bkoz@redhat.com>

	* src/allocator-inst.cc: Explicitly instantiate.
