	(dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
	&& GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
	GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
	(NEED_MEM_INSERT): New macro.
	(mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.

	* s/cygwin.h: The vfork the #define in cygwin.h was protecting
	against is gone.  It's better to use vfork now so that when Cygwin
	gains a new, working vfork, we use it automatically (bug#10398).

	* xdisp.c (set_cursor_from_row): If the display string appears in
	the buffer at position that is closer to point than the position
	after the display string, display the cursor on the first glyph of
	the display string.  Fixes cursor display when a 'display' text
	property immediately follows invisible text.  (Bug#11094)

2012-04-09  Paul Eggert  <eggert@cs.ucla.edu>

	composite.c: use 'double' consistently
	* composite.c (get_composition_id): Use 'double' consistently
	instead of converting 'float' to 'double' and vice versa; this is

	* alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.

	objects, as mark_maybe_pointer will catch them otherwise.

	[!WINDOWSNT]: New macros.

	Call init_libxml2_functions before calling libxml2 functions.
223 224 225 226 227 228 229 230
	(syms_of_xml) <Qlibxml2_dll>: DEFSYM it.

	* emacs.c: Don't include libxml/parser.h.
	(shut_down_emacs): Call xml_cleanup_parser, instead of calling
	xmlCleanupParser directly.

2012-04-07  Eli Zaretskii  <eliz@gnu.org>

	* buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
	* character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
	about subtle differences between FETCH_CHAR* and STRING_CHAR*
	macros related to unification of CJK characters.  For the details,

262 263 264 265 266
	* xdisp.c (move_it_by_lines): When DVPOS is positive, and the
	position we get to after a call to move_it_to fails the
	IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
	only if we wind up in a string from display property.  (Bug#11063)

267 268 269 270
	* window.c (Fdelete_other_windows_internal): Invalidate the row
	and column information about mouse highlight, so that redisplay
	restores it after reallocating the glyph matrices.  (Bug#7464)

271 272 273 274
	* xdisp.c (set_cursor_from_row): If `cursor' property on a display

	position of that property as if we actually saw that position in
	the row's glyphs.
275 276 277 278
	(move_it_by_lines): Remove the assertion that
	"it->current_x == 0 && it->hpos == 0" which can be legitimately
	violated when there's a before-string at the beginning of a line.
	(Bug#11063)

	extending the face to the end of the line.
	(display_line): Call extend_face_to_end_of_line when the default
	face was remapped.  (Bug#11068)

289 290 291 292

	* bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
	FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES.  Prevents crashes
	when fetching a multibyte character consumes more bytes than

2012-03-18  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (cursor_row_p): Even if the glyph row ends in a string
	that is not from display property, accept the row as a "cursor
	row" if one of the string's character has a non-nil `cursor'
	property.  Fixes cursor positioning when there are newlines in
	overlay strings, e.g. in icomplete.el.  (Bug#11035)

	Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
	Otherwise, valgrind does not work on some platforms.
	Problem reported by Andreas Schwab in
1288 1289 1290 1291 1292 1293 1294 1295 1296 1297 1298 1299 1300 1301 1302
	<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)

	(compute_line_metrics): Call row_hash, instead of computing the

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