	iterator by calling bidi_pop_it same number of times.
	(reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
	and we are bidi-iterating, don't decrement the iterator position;
	instead, set the first_elt flag in the bidi iterator, to produce

2011-05-07  Ben Key  <bkey76@gmail.com>

	* makefile.w32-in: The bootstrap-temacs rule now makes use of
	one of two shell specific rules, either bootstrap-temacs-CMD or
	bootstrap-temacs-SH.  The bootstrap-temacs-SH rule is identical
	to the previous implementation of the bootstrap-temacs rule.
	The bootstrap-temacs-CMD rule is similar to the previous
	implementation of the bootstrap-temacs rule except that it
	makes use of the ESC_CFLAGS variable instead of the CFLAGS
	variable.

	These changes, along with some changes to nt/configure.bat,
	nt/gmake.defs, and nt/nmake.defs, are required to extend my
	earlier fix to add support for --cflags and --ldflags options
	that include quotes so that it works whether make uses cmd or
	sh as the shell.

546 547 548

	(EMACS_UINTPTR): Likewise, with uintptr_t.

549 550 551 552
	* lisp.h: Prefer 64-bit EMACS_INT if available.
	(EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
	on 32-bit hosts that have 64-bit int, so that they can access
	large files.
553 554
	However, temporarily disable this change unless the temporary
	symbol WIDE_EMACS_INT is defined.
555

556 557
	* lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.

558 559 560 561 562 563 564 565 566 567 568 569 570 571 572 573 574 575 576 577 578 579 580 581 582 583 584 585 586 587
	Prefer intptr_t/uintptr_t for integers the same widths as pointers.
	This removes an assumption that EMACS_INT and long are the same
	width as pointers.  The assumption is true for Emacs porting targets
	now, but we want to make other targets possible.
	* lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
	(EMACS_INTPTR, EMACS_UINTPTR): New macros.
	In the rest of the code, change types of integers that hold casted
	pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
	replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
	(XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
	(XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
	No need to cast type when ORing.
	(XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
	* alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
	* doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
	assume EMACS_INT is the same width as char *.
	* gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
	(xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
	Remove no-longer-needed casts.
	(xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
	(xg_tool_bar_help_callback, xg_make_tool_item):
	Use EMACS_INTPTR to hold an integer
	that will be cast to void *; this can avoid a GCC warning
	if EMACS_INT is not the same width as void *.
	* menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
	* xdisp.c (display_echo_area_1, resize_mini_window_1):
	(current_message_1, set_message_1):
	Use a local to convert to proper width without a cast.
	* xmenu.c (dialog_selection_callback): Likewise.

588 589 590 591 592 593
	* sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
	Also, don't assume VALBITS / RAND_BITS is less than 5,
	and don't rely on undefined behavior when shifting a 1 left into
	the sign bit.
	* lisp.h (get_random): Change signature to match.

594 595 596 597 598 599 600 601
	* lread.c (hash_string): Use size_t, not int, for hash computation.
	Normally we prefer signed values; but hashing is special, because
	it's better to use unsigned division on hash table sizes so that
	the remainder is nonnegative.  Also, size_t is the natural width
	for hashing into memory.  The previous code used 'int', which doesn't
	retain enough info to hash well into very large tables.
	(oblookup, oblookup_last_bucket_number, Funintern): Likewise.

602 603 604 605 606
	* dbusbind.c: Don't possibly lose pointer info when converting.
	(xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
	Use XPNTR rather than XHASH, so that the high-order bits of
	the pointer aren't lost when converting through void *.

607 608
	* eval.c (Fautoload): Don't double-shift a pointer.

609 610
	* fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

	* lisp.h: Fix a problem with aliasing and vector headers.  (Bug#8546)
847 848 849 850 851 852 853
	GCC 4.6.0 optimizes based on type-based alias analysis.  For
	example, if b is of type struct buffer * and v of type struct
	Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
	!= &v->size, and therefore "v->size = 1; b->size = 2; return
	v->size;" must therefore return 1.  This assumption is incorrect
	for Emacs, since it type-puns struct Lisp_Vector * with many other
	types.  To fix this problem, this patch adds a new type struct

	vectorlike_header that documents the constraints on layout of vectors

899 900 901 902 903 904 905 906 907 908
	* data.c (atof): Remove decl; no longer used or needed.
	(digit_to_number): Move to lread.c.
	(Fstring_to_number): Use new string_to_number function, to be
	consistent with how the Lisp reader treats infinities and NaNs.
	Do not assume that floating-point numbers represent EMACS_INT
	without losing information; this is not true on most 64-bit hosts.
	Avoid double-rounding errors, by insisting on integers when
	parsing non-base-10 numbers, as the documentation specifies.
	* lisp.h (string_to_number): New decl, replacing ...
	(isfloat_string): Remove.
909
	* lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
910
	(read1): Do not accept +. and -. as integers; this
911 912 913 914 915 916 917 918 919 920 921 922 923
	appears to have been a coding error.  Similarly, do not accept
	strings like +-1e0 as floating point numbers.  Do not report
	overflow for integer overflows unless the base is not 10 which
	means we have no simple and reliable way to continue.
	Break out the floating-point parsing into a new
	function string_to_number, so that Fstring_to_number parses
	floating point numbers consistently with the Lisp reader.
	(digit_to_number): Moved here from data.c.  Make it static inline.
	(E_CHAR, EXP_INT): Remove, replacing with ...
	(E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
	(string_to_number): New function, replacing isfloat_string.
	This function checks for valid syntax and produces the resulting
	Lisp float number too.  Rework it so that string-to-number
924
	no longer mishandles examples like "1.0e+".  Use strtoumax,
925 926
	so that overflow for non-base-10 numbers is reported only when
	there's no portable and simple way to convert to floating point.
927

928 929 930

	Comment out unused local.  Fix pointer signedness problems.

953 954 955 956
	* lread.c (openp): Don't stuff size_t into an 'int'.
	Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
	about possible signed overflow.

957 958 959 960 961

	Replace pEd with more-general pI, and fix some printf arg casts.
	* lisp.h (pI): New macro, generalizing old pEd macro to other

991 992

1003 1004 1005 1006 1007
	* frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
	here, since it parses constructs like leading '-' and spaces,
	which are not wanted; and it overflows with large numbers.
	Instead, simply match F[0-9]+, which is what is wanted anyway.

	(allocate_vectorlike, make_pure_vector): Use the new macros,
	plus offsetof, to remove unportable assumptions about struct layout.
	These assumptions hold on all porting targets that I know of, but
	they are not guaranteed, they're easy to remove, and removing them
	makes further changes easier.

1017 1018
	* alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
	This doesn't fix a bug but makes the code clearer.
1019 1020
	(string_overrun_cookie): Now const.  Use initializers that
	don't formally overflow signed char, to avoid warnings.
1021 1022
	(allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
	can cause Emacs to crash when string overrun checking is enabled.
1023 1024 1025
	(allocate_buffer): Don't assume sizeof (struct buffer) is a
	multiple of sizeof (EMACS_INT); it need not be, if
	alignof(EMACS_INT) < sizeof (EMACS_INT).
1026
	(check_sblock, check_string_bytes, check_string_free_list): Protoize.

	* nsfont.m: Fixed bugs in ns_get_family and
	ns_descriptor_to_entity that were caused by using free to

	XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
	--enable-checking=xmallocoverrun).  xfree is now used to
	deallocate these memory blocks.
