140 141 142
	Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
	Otherwise, valgrind does not work on some platforms.
	Problem reported by Andreas Schwab in
143 144 145 146 147 148 149 150 151 152 153 154 155 156 157
	<http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
	* puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
	is set, removing the need for VIRT_ADDRESS_VARIES.
	(PURE_P): Use a more-efficient implementation that needs just one
	comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
	number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
	to 4 (xorl, subq, cmpq, setbe).
	* alloc.c (pure): Always extern now, since that's the
	VIRT_ADDR_VARIES behavior.
	(PURE_POINTER_P): Use a single comparison, not two, for
	consistency with the new puresize.h.
	* lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
	* m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
	Remove VIRT_ADDR_VARIES no longer needed.

	* xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
	(erase_phys_cursor, update_window_cursor, show_mouse_face)
	(cursor_in_mouse_face_p): If the cursor position is out of bounds,
	behave as if the cursor position were at the window margin.

	* window.c (get_phys_cursor_glyph): If the window is hscrolled,
	and the cursor position is out of bounds, behave as if the cursor
	position were at the window margin.  (Bug#10075)

169 170 171 172 173 174
2011-11-18  Chong Yidong  <cyd@gnu.org>

	* window.c (Fwindow_combination_limit): Make first argument
	non-optional, since it is meaningless for live windows like the
	selected window.

175 176 177 178
2011-11-18  Dmitry Antipov  <dmantipov@yandex.ru>

	hash values of the two rows.  (Bug#10035)
190
	(add_row_entry): Add xassert to verify that ROW's hash code is valid.
191 192 193 194 195 196 197 198 199 200 201

	* xdisp.c (row_hash): New function, body extracted from
	compute_line_metrics.
	(compute_line_metrics): Call row_hash, instead of computing the
	hash code inline.

	* dispnew.c (verify_row_hash): Call row_hash for computing the
	hash code of a row, instead of duplicating code from xdisp.c.

	* dispextern.h (row_hash): Add prototype.

2011-11-18  Tassilo Horn  <tassilo@member.fsf.org>

	* xdisp.c (display_line): Move the call to
	highlight_trailing_whitespace before the call to

	faces of all the glyphs to compute ROW's hash value.  Fixes
	assertion violations in row_equal_p.  (Bug#10035)

	Avoid some portability problems by eschewing 'extern inline' functions.

	Fix some portability problems with 'inline'.
	* dispextern.h (window_box, window_box_height, window_text_bottom_y)
	(window_box_width, window_box_left, window_box_left_offset)
	(window_box_right, window_box_right_offset): Declare extern.
	Otherwise, these inline functions do not conform to C99 and
	are miscompiled by Microsoft compilers.  Reported by Eli Zaretskii in

	(static_offset_intervals): Remove.
	(offset_intervals): Rewrite using the old contents of
	static_offset_intervals.  The old version didn't conform to C99
	because an extern inline function contained a reference to an
	identifier with static linkage.

	Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
	* editfns.c: Rewrite current-time-zone so that it invokes
	the equivalent of (format-time-string "%Z") to get the time zone name.
	This fixes a bug when the time zone name contains characters that

	This fixes a shortcoming that I introduced in my 1999-10-19 patch:

	separator (a.k.a. Newline).  This avoids running the same
	expensive loop twice, once when we consume the preceding newline
	and the other time when the line actually needs to be displayed.
	Avoid the loop when we see neutrals on the base embedding level
	following a character whose directionality is the same as the
	paragraph's.  This avoids running the expensive loop when a line
	ends in a long sequence of neutrals, like control characters.
	Add assertion against STRONG_AL type.  Slightly rearrange code

	isnan: Fix porting problem to Solaris 10 with bundled gcc.
	Without this fix, the command to link temacs failed due to an
	undefined symbol __builtin_isnan.  This is because
	/usr/include/iso/math_c99.h #defines isnan(x) to
	__builtin_isnan(x), but the bundled gcc, which identifies itself
	as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
	a __builtin_isnan.
	* floatfns.c (isnan): #undef, and then #define to a clone of

	(Fisnan): Always define, since it's always available now.

	The previous code assumed that file offsets (off_t values) fit in
	EMACS_INT variables, which is not true on typical 32-bit hosts.
	The code messed up by falsely reporting buffer overflow in cases
	such as (insert-file-contents "big" nil 1 2) into an empty buffer
	when "big" contains more than 2**29 bytes, even though this
	inserts just one byte and does not overflow the buffer.
	(Finsert_file_contents): Store file offsets as off_t
	values, not as EMACS_INT values.  Check for overflow when
	converting between EMACS_INT and off_t.  When checking for
	buffer overflow or for overlap, take the offsets into account.
	Don't use EMACS_INT for small values where int suffices.
	When checking for overlap, fix a typo: ZV was used where
	ZV_BYTE was intended.
	(Fwrite_region): Don't assume off_t fits into 'long'.
	* buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
