	(validate_region): Omit unnecessary test for b <= e,
	since that's guaranteed by the previous test.
40 41 42 43 44 45 46
	(adjust_overlays_for_delete): Avoid pos + length overflow.
	(Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
	(report_overlay_modification):
	Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
	(Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
	Omit pointer cast, which isn't needed anyway, and doesn't work
	after the EMACS_INT -> ptrdiff_t change.
47 48 49 50 51 52
	(Fmove_overlay): Delete an evaporating overlay
	if it becomes empty after its bounds are adjusted to fit within
	its buffer.  Without this fix, in a nonempty buffer (let ((o
	(make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
	yields an empty overlay that has the evaporate property, which is
	not supposed to happen.  (Bug#9642)
53 54 55 56
	* buffer.h: Adjust decls to match defn changes elsewhere.
	(struct buffer_text, struct buffer):
	Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
	Use EMACS_INT, not int, where int might not be wide enough.
57 58 59 60 61 62
	* bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
	not int, to avoid needless 32-bit limit on 64-bit hosts.
	(exec_byte_code): Use tighter memory-full test, one that checks
	for alloca overflow.  Don't compute the address of the object just
	before an array, as that's not portable.  Use EMACS_INT, not
	ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78
	* callint.c (Fcall_interactively):
	Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
	* callproc.c (call_process_kill, Fcall_process):
	Don't assume pid_t fits into an Emacs fixnum.

	(Fcall_process_region):
	Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

	Use int, not EMACS_INT, where int will do.
	* casefiddle.c (casify_object, casify_region, operate_on_word)
	(Fupcase_word, Fdowncase_word, Fcapitalize_word):
	Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
	(casify_object): Avoid integer overflow when overallocating buffer.
	* casetab.c (set_identity, shuffle): Prefer int to unsigned when
79
	either works.  Use lint_assume to convince GCC 4.6.1 that it's OK.
80 81 82 83 84 85 86
	* category.c (Fchar_category_set): Don't assume fixnum fits in int.
	* category.h (CATEGORYP): Don't assume arg is nonnegative.
	* ccl.c (GET_CCL_INT): Remove; no longer needed, since the
	integers are now checked earlier.  All uses replaced with XINT.
	(ccl_driver):
	Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
	For CCL_MapSingle, check that content and value are in int range.
87 88
	(ccl_driver, Fregister_code_conversion_map):
	Check that Vcode_version_map_vector is a vector.
89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108
	(resolve_symbol_ccl_program): Check that vector header is in range.
	Always copy the vector, so that we can check its contents reliably
	now rather than having to recheck each instruction as it's being
	executed.  Check that vector words fit in 'int'.
	(ccl_get_compiled_code, Fregister_ccl_program)
	(Fregister_code_conversion_map): Use ptrdiff_t, not int, for
	program indexes, to avoid needless 32-bit limit on 64-bit hosts.
	(Fccl_execute, Fccl_execute_on_string): Check that initial reg
	contents are in range.
	(Fccl_execute_on_string): Check that status is in range.
	* ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
	* character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
	Accept and return EMACS_INT, not int, because callers can pass values
	out of 'int' range.

	(str_as_unibyte, str_to_unibyte, string_count_byte8)
	(string_escape_byte8, Fget_byte):
	Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
109
	(Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
110 111 112 113 114 115 116
	avoid mishandling large integers.
	* character.h: Adjust decls to match defn changes elsewhere.
	* charset.c (load_charset_map_from_file, find_charsets_in_text)
	(Ffind_charset_region):
	Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
	(load_charset_map_from_file): Redo idx calculation to avoid overflow.
	(load_charset_map_from_vector, Fdefine_charset_internal):
117
	Don't assume fixnum fits in int.
118 119 120
	(load_charset_map_from_vector, Fmap_charset_chars):
	Remove now-unnecessary CHECK_NATNUMs.
	(Fdefine_charset_internal): Check ranges here, more carefully.
121 122 123 124 125 126 127 128 129 130 131 132
	Don't rely on undefined behavior with signed left shift overflow.
	Don't assume unsigned int fits into fixnum, or that fixnum fits
	into unsigned int.  Don't require max_code to be a valid fixnum;
	that's not true for gb10830 4-byte on a 32-bit host.  Allow
	invalid_code to be a cons, for the same reason.  Require code_offset
	to be a character.  Avoid int overflow if max_char is close
	to INT_MAX.
	(CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
	this is intended anyway and avoids some undefined behavior.
	(load_charset_map): Pass unsigned, not int, as 2nd arg of
	INDEX_TO_CODE_POINT, as that's what it expects.
	(Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
133 134 135 136 137 138 139
	* charset.h (DECODE_CHAR): Return int, not unsigned;
	this is what was intended anyway, and it avoids undefined behavior.
	(CHARSET_OFFSET): Remove unused macro, instead of fixing its
	integer-overflow issues.
	(ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
	Formerly, it returned EMACS_INT on 64-bit hosts in the common case
	where the argument is EMACS_INT, and this behavior is not intended.
140 141 142 143 144 145
	* chartab.c (Fmake_char_table, Fset_char_table_range)
	(uniprop_get_decoder, uniprop_get_encoder):
	Don't assume fixnum fits in int.
	* cmds.c (move_point): New function, that does the gist of
	Fforward_char and Fbackward_char, but does so while checking
	for integer overflow more accurately.
146
	(Fforward_char, Fbackward_char): Use it.
147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177
	(Fforward_line, Fend_of_line, internal_self_insert)
	(internal_self_insert):
	Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
	Fix a FIXME, by checking for integer overflow when calculating
	target_clm and actual_clm.

	(ASSURE_DESTINATION, coding_alloc_by_realloc)

	(setup_iso_safe_charsets, consume_chars, Funencodable_char_position)
	(Fdefine_coding_system_internal):

	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
	need converting from the system time locale to Emacs internal format.
	This fixes a shortcoming that I introduced in my 1999-10-19 patch:
	that patch fixed format-time-string to do the conversion, but
	I forgot to fix current-time-zone.
	(format_time_string): New function, containing most of
	what Fformat_time_string used to contain.
	(Fformat_time_string): Rewrite in terms of format_time_string.
	This doesn't change this function's behavior.
	(current-time-zone): Rewrite to use format_time_string.
	This fixes the bug reported by Michael Schierl in
	<http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
	Jason Rumney's 2007-06-07 change worked around this bug, but
	didn't fix it.

	Fix part 3 of bug#9771.
	* bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
	(bidi_resolve_neutral): Don't enter the expensive loop looking for
	non-neutral characters if the current character is a paragraph
	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
	that determines the type of a neutral given the first non-neutral
	that follows it.
	(bidi_level_of_next_char): Set next_en_pos to zero when
	invalidating its info.

	/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
	what's in data.c.
	(Fisnan): Always define, since it's always available now.
	(syms_of_floatfns): Always define isnan at the Lisp level.

	* fileio.c: Fix bugs with large file offsets (Bug#9428).

	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.
