	* xdisp.c (iterate_out_of_display_property): xassert that
	IT->position is set to within IT->object's boundaries.  Break from

	Set IT->current to match the bidi iterator unconditionally.
187 188 189 190 191 192 193
	(push_display_prop): Allow GET_FROM_STRING as IT->method on
	entry.  Force push_it to save on the stack the current
	buffer/string position, to be restored by pop_it.  Fix flags in
	the iterator structure wrt the object coming from a display
	property, as `line-prefix' and `wrap-prefix' are not ``replacing''
	properties.  (Bug#9284)

435 436 437 438 439 440 441 442 443 444 445 446 447
	* bidi.c: Integer size and overflow fixes.
	(bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
	(bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
	(bidi_cache_find_level_change, bidi_cache_ensure_space)
	(bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
	(bidi_find_other_level_edge):
	Use ptrdiff_t instead of EMACS_INT where either will do.
	This works better on 32-bit hosts configured --with-wide-int.
	(bidi_cache_ensure_space): Check for size-calculation overflow.
	Use % rather than repeated addition, for better worst-case speed.
	Don't set bidi_cache_size until after xrealloc returns, because it
	might not return.
	(bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
448 449 450
	(bidi_cache_ensure_space): Also check that the bidi cache size
	does not exceed that of the largest Lisp string or buffer.  See Eli
	Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
451

452 453 454 455
	* alloc.c (__malloc_size_t): Remove.
	All uses replaced by size_t.  See Andreas Schwab's note
	<http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.

456 457 458 459 460 461 462 463 464 465 466 467 468 469 470 471 472 473 474
	* image.c: Improve checking for integer overflow.
	(check_image_size): Assume that f is nonnull, since
	it is always nonnull in practice.  This is one less thing to
	worry about when checking for integer overflow later.
	(x_check_image_size): New function, which checks for integer
	overflow issues inside X.
	(x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
	This removes the need for a memory_full check.
	(xbm_image_p): Rewrite to avoid integer multiplication overflow.
	(Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
	(xbm_read_bitmap_data): Change locals back to 'int', since
	their values must fit in 'int'.
	(xpm_load_image, png_load, tiff_load):
	Invoke x_create_x_image_and_pixmap earlier,
	to avoid much needless work if the image is too large.
	(tiff_load): Treat overly large images as if
	x_create_x_image_and_pixmap failed, not as malloc failures.
	(gs_load): Use x_check_image_size.

479 480
	* image.c (png_load): Don't assume height * row_bytes fits in 'int'.

481 482 483 484
	* xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
	Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
	would wrongly return t on a 64-bit host.

485 486 487 488 489
	* dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
	The plain *_OVERFLOW macros run afoul of GCC bug 49705
	<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
	and therefore cause GCC to emit a bogus diagnostic in some cases.

	* image.c: Integer signedness and overflow and related fixes.
	This is not an exhaustive set of fixes, but it's time to
	record what I've got.
	(lookup_pixel_color, check_image_size): Remove redundant decls.
	(check_image_size): Don't assume that arbitrary EMACS_INT values
	fit in 'int', or that arbitrary 'double' values fit in 'int'.
	(x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
	(tiff_load, imagemagick_load_image):
	Check for overflow in size calculations.
	(x_create_x_image_and_pixmap): Remove unnecessary test for
	xmalloc returning NULL; that can't happen.
	(xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
	(xpm_color_bucket): Use better integer hashing function.
	(xpm_cache_color): Don't possibly over-allocate memory.
	(struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
	(gif_memory_source):
	Use ptrdiff_t, not int or size_t, to record sizes.
	(png_load): Don't assume values greater than 2**31 fit in 'int'.
	(our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
	either works, as we prefer signed integers.
	(tiff_read_from_memory, tiff_write_from_memory):
	Return tsize_t, not size_t, since that's what the TIFF API wants.
	(tiff_read_from_memory): Don't fail simply because the read would
	go past EOF; instead, return a short read.
	(tiff_load): Omit no-longer-needed casts.
	(Fimagemagick_types): Don't assume size fits into 'int'.

517 518 519 520 521 522 523 524 525 526
	Improve hashing quality when configured --with-wide-int.
	* fns.c (hash_string): New function, taken from sxhash_string.
	Do not discard information about ASCII character case; this
	discarding is no longer needed.
	(sxhash-string): Use it.  Change sig to match it.  Caller changed.
	* lisp.h: Declare it.
	* lread.c (hash_string): Remove, since we now use fns.c's version.
	The fns.c version returns a wider integer if --with-wide-int is
	specified, so this should help the quality of the hashing a bit.

527 528 529 530 531
	* emacs.c: Integer overflow minor fix.
	(heap_bss_diff): Now uprintmax_t, not unsigned long.  All used changed.
	Define only if GNU_LINUX.
	(main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.

532 533 534 535 536 537 538 539 540 541 542 543 544
	* dispnew.c: Integer signedness and overflow fixes.
	Remove unnecessary forward decls, that were a maintenance hassle.
	(history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
	All uses changed.
	(adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
	(scrolling_window): Use ptrdiff_t, not int, for byte count.
	(prepare_desired_row, line_draw_cost):
	Use int, not unsigned, where either works.
	(save_current_matrix, restore_current_matrix):
	Use ptrdiff_t, not size_t, where either works.
	(init_display): Check for overflow more accurately, and without
	relying on undefined behavior.

545 546 547 548 549 550 551 552 553 554
	* editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
	Remove, replacing with the new symbols in lisp.h.  All uses changed.
	* fileio.c (make_temp_name):
	* filelock.c (lock_file_1, lock_file):
	* xdisp.c (message_dolog):
	Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
	Use pMd etc. instead.
	* lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
	replacing the pWIDE etc. symbols removed from editfns.c.

555 556 557 558
	* keyboard.h (num_input_events): Now uintmax_t.
	This is (very slightly) less likely to mess up due to wraparound.
	All uses changed.

559 560 561 562 563
	* buffer.c: Integer signedness fixes.
	(alloc_buffer_text, enlarge_buffer_text):
	Use ptrdiff_t rather than size_t when either will do, as we prefer
	signed integers.

564 565 566 567 568 569 570 571 572 573 574 575 576 577 578 579 580 581 582 583 584 585 586 587
	* alloc.c: Integer signedness and overflow fixes.
	Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
	(__malloc_size_t): Default to size_t, not to int.
	(pure_size, pure_bytes_used_before_overflow, stack_copy_size)
	(Fgarbage_collect, mark_object_loop_halt, mark_object):
	Prefer ptrdiff_t to size_t when either would do, as we prefer
	signed integers.
	(XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
	(xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
	Now const.  Initialize with values that are in range even if char
	is signed.
	(XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
	(xmalloc_put_size, xmalloc_get_size): New functions.  All uses changed.
	These functions do the right thing with sizes > 2**32.
	(check_depth): Now ptrdiff_t, not int.
	(overrun_check_malloc, overrun_check_realloc, overrun_check_free):
	Adjust to new way of storing sizes.  Check for size overflow bugs
	in rest of code.
	(STRING_BYTES_MAX): Adjust to new overheads.  The old code was
	slightly wrong anyway, as it missed one instance of
	XMALLOC_OVERRUN_CHECK_OVERHEAD.
	(refill_memory_reserve): Omit needless cast to size_t.
	(mark_object_loop_halt): Mark as externally visible.

588 589 590 591 592 593 594
	* xselect.c: Integer signedness and overflow fixes.
	(Fx_register_dnd_atom, x_handle_dnd_message):
	Use ptrdiff_t, not size_t, since we prefer signed.
	(Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
	* xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
	x_dnd_atoms_size and x_dnd_atoms_length.

595 596 597 598 599 600 601 602 603 604 605
	* doprnt.c: Prefer signed to unsigned when either works.
	* eval.c (verror):
	* doprnt.c (doprnt):
	* lisp.h (doprnt):
	* xdisp.c (vmessage):
	Use ptrdiff_t, not size_t, when using or implementing doprnt,
	since the sizes cannot exceed ptrdiff_t bounds anyway, and we
	prefer signed arithmetic to avoid comparison confusion.
	* doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
	but is a bit tricky.

606 607 608 609 610 611 612 613 614 615 616 617
	Assume freestanding C89 headers, string.h, stdlib.h.
	* data.c, doprnt.c, floatfns.c, print.c:
	Include float.h unconditionally.
	* gmalloc.c: Assume C89-at-least behavior for preprocessor,
	limits.h, stddef.h, string.h.  Use memset instead of 'flood'.
	* regex.c: Likewise for stddef.h, string.h.
	(ISASCII): Remove; can assume it returns 1 now.  All uses removed.
	* s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
	* s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
	(STDC_HEADERS): Remove obsolete defines.
	* sysdep.c: Include limits.h unconditionally.

666 667

	position for TO_CHARPOS while scanning the line, and restore it on
668 669
	exit if none of the characters scanned was an exact match.
	Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay

	Random fixes.  E.g., (random) never returned negative values.
	* fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
	subseconds part to the entropy, as that's a bit more random.
	Prefer signed to unsigned, since the signedness doesn't matter and
	in general we prefer signed.  When given a limit, use a
	denominator equal to INTMASK + 1, not to VALMASK + 1, because the
	latter isn't right if USE_2_TAGS_FOR_INTS.
	* sysdep.c (get_random): Return a value in the range 0..INTMASK,
	not 0..VALMASK.  Don't discard "excess" bits that random () returns.
