	Remove unnecessary casts.
	* xterm.c (x_term_init):
	* xfns.c (x_set_border_pixel):
	* widget.c (create_frame_gcs): Remove casts to unsigned long etc.
	These aren't needed now that we assume ANSI C.

9 10 11 12
	* sound.c (Fplay_sound_internal): Remove cast to unsigned long.
	It's more likely to cause problems (due to unsigned overflow)
	than to cure them.

13 14
	* dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.

15 16
	* unexelf.c (unexec): Don't assume BSS addr fits in unsigned.

17 18
	* xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.

19 20
	* keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.

21 22
	* lisp.h (CHAR_TABLE_SET): Omit now-redundant test.

23 24
	* lread.c (Fload): Don't compare a possibly-garbage time_t value.

25 26 27 28 29 30
	GLYPH_CODE_FACE returns EMACS_INT, not int.
	* dispextern.h (merge_faces):
	* xfaces.c (merge_faces):
	* xdisp.c (get_next_display_element):
	(next_element_from_display_vector): Don't assume EMACS_INT fits in int.

31 32 33
	* character.h (CHAR_VALID_P): Remove unused parameter.
	* fontset.c, lisp.h, xdisp.c: All uses changed.

34 35
	* editfns.c (Ftranslate_region_internal): Omit redundant test.

36 37 38 39 40 41
	* fns.c (concat): Minor tuning based on overflow analysis.
	This doesn't fix any bugs.  Use int to hold character, instead
	of constantly refetching from Emacs object.  Use XFASTINT, not
	XINT, for value known to be a character.  Don't bother comparing
	a single byte to 0400, as it's always less.

42
	* floatfns.c (Fexpt):
43 44
	* fileio.c (make_temp_name): Omit unnecessary cast to unsigned.

45 46 47
	* editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
	for characters.

48 49
	* doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.

50 51 52 53 54
	* data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
	Without this fix, on a 64-bit host (aset S 0 4294967386) would
	incorrectly succeed when S was a string, because 4294967386 was
	truncated before it was used.

55 56 57 58
	* chartab.c (Fchar_table_range): Use CHARACTERP to check range.
	Otherwise, an out-of-range integer could cause undefined behavior
	on a 64-bit host.

59 60 61 62 63 64
	* composite.c: Use int, not EMACS_INT, for characters.
	(fill_gstring_body, composition_compute_stop_pos): Use int, not
	EMACS_INT, for values that are known to be in character range.
	This doesn't fix any bugs but is the usual style inside Emacs and
	may generate better code on 32-bit machines.

65 66 67 68 69 70 71 72
	Make sure a 64-bit char is never passed to ENCODE_CHAR.
	This is for reasons similar to the recent CHAR_STRING fix.
	* charset.c (Fencode_char): Check that character arg is actually
	a character.  Pass an int to ENCODE_CHAR.
	* charset.h (ENCODE_CHAR): Verify that the character argument is no
	wider than 'int', as a compile-time check to prevent future regressions
	in this area.

73
	* character.c (char_string): Remove unnecessary casts.
74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93

	Make sure a 64-bit char is never passed to CHAR_STRING.
	Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
	by silently ignoring the top 32 bits, allowing some values
	that were far too large to be valid characters.
	* character.h: Include <verify.h>.
	(CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
	arguments are no wider than unsigned, as a compile-time check
	to prevent future regressions in this area.
	* data.c (Faset):
	* editfns.c (Fchar_to_string, general_insert_function, Finsert_char):
	(Fsubst_char_in_region):
	* fns.c (concat):
	* xdisp.c (decode_mode_spec_coding):
	Adjust to CHAR_STRING's new requirement.
	* editfns.c (Finsert_char, Fsubst_char_in_region):
	* fns.c (concat): Check that character args are actually
	characters.  Without this test, these functions did the wrong
	thing with wildly out-of-range values on 64-bit hosts.

96 97 98 99 100
	Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
	These casts should not be needed on 32-bit hosts, either.
	* keyboard.c (read_char):
	* lread.c (Fload): Remove casts to unsigned.

101 102 103 104 105 106 107 108 109 110
	* lisp.h (UNSIGNED_CMP): New macro.
	This fixes comparison bugs on 64-bit hosts.
	(ASCII_CHAR_P): Use it.
	* casefiddle.c (casify_object):
	* character.h (ASCII_BYTE_P, CHAR_VALID_P):
	(SINGLE_BYTE_CHAR_P, CHAR_STRING):
	* composite.h (COMPOSITION_ENCODE_RULE_VALID):
	* dispextern.h (FACE_FROM_ID):
	* keyboard.c (read_char): Use UNSIGNED_CMP.

113 114 115
	* xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
	not to EMACS_INT, to avoid GCC warning.

116 117
	* xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.

118 119 120
	* buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
	The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
	isn't needed on 32-bit machines.
121

122
	* buffer.c (Fgenerate_new_buffer_name): Use EMACS_INT for count, not int.
123
	(advance_to_char_boundary): Return EMACS_INT, not int.
124 125 126

	* data.c (Qcompiled_function): Now static.

127 128
	* window.c (window_body_lines): Now static.

129 130
	* image.c (gif_load): Rename local to avoid shadowing.

131 132 133 134 135 136 137 138
	* lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
	(struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
	* alloc.c (make_save_value): Integer argument is now of type
	ptrdiff_t, not int.
	(mark_object): Use ptrdiff_t, not int.
	* lisp.h (pD): New macro.
	* print.c (print_object): Use it.

139 140 141 142 143 144 145 146 147
	* alloc.c: Use EMACS_INT, not int, to count objects.
	(total_conses, total_markers, total_symbols, total_vector_size)
	(total_free_conses, total_free_markers, total_free_symbols)
	(total_free_floats, total_floats, total_free_intervals, total_intervals)
	(total_strings, total_free_strings):
	Now EMACS_INT, not int.  All uses changed.
	(Fgarbage_collect): Compute overall total using a double, so that
	integer overflow is less likely to be a problem.  Check for overflow
	when converting back to an integer.
148 149 150 151
	(n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
	(n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
	These were 'int' variables that could overflow on 64-bit hosts;
	they were never used, so remove them instead of repairing them.
152
	(nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
153 154 155
	(inhibit_garbage_collection): Set gc_cons_threshold to max value.
	Previously, this ceilinged at INT_MAX, but that doesn't work on
	64-bit machines.
156
	(allocate_pseudovector): Don't use EMACS_INT when int would do.
157

158
	* alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
159
	(allocate_vectorlike): Check for ptrdiff_t overflow.
160 161 162
	(mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
	when a (possibly-narrower) signed value would do just as well.
	We prefer using signed arithmetic, to avoid comparison confusion.
163

164 165 166 167 168 169 170 171 172 173
	* alloc.c: Catch some string size overflows that we were missing.
	(XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
	for convenience in STRING_BYTES_MAX.
	(STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
	The definition here is exact; the one in lisp.h was approximate.
	(allocate_string_data): Check for string overflow.  This catches
	some instances we weren't catching before.  Also, it catches
	size_t overflow on (unusual) hosts where SIZE_MAX <= min
	(PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
	and ptrdiff_t and EMACS_INT are both 64 bits.
174

175 176 177 178
	* character.c, coding.c, doprnt.c, editfns.c, eval.c:
	All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
	* lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.

179 180
	* character.c (string_escape_byte8): Fix nbytes/nchars typo.

181 182
	* alloc.c (Fmake_string): Check for out-of-range init.

	handle_display_spec instead of single_display_spec_intangible_p.
626 627

	* lisp.h: Change signatures accordingly.
	* alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
	All callers changed.  (Bug#8762)

	* gnutls.c: Use Emacs's memory allocators.
	Without this change, the gnutls library would invoke malloc etc.
	directly, which causes problems on non-SYNC_INPUT hosts, and which
	runs afoul of improving memory_full behavior.  (Bug#8761)
	(fn_gnutls_global_set_mem_functions): New macro or function pointer.
	(emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
	xfree instead of the default malloc, realloc, free.
	(Fgnutls_boot): No need to check for memory allocation failure,
	since xmalloc does that for us.

	approximate and thus did not catch overflow reliably.  Instead, walk
	through the format just once, formatting and computing sizes as we go,
	checking for integer overflow at every step, and allocating a larger
	buffer as needed.  Keep track separately whether the format is
	multibyte.  Keep only the most-recently calculated precision, rather

	Be more systematic about user-interface timestamps.
	Before, the code sometimes used 'Time', sometimes 'unsigned long',

	Don't assume that the difference between two unsigned long values

	instead of EMACS_INT, since it always fits in int.
1178

1179 1180
	* menu.c (grow_menu_items): Check for int overflow.

1181 1182

1183 1184 1185 1186 1187 1188 1189 1190 1191
	* xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
	Before, the code was not consistent.  These values cannot exceed
	2**31 - 1 so there's no need to make them unsigned.
	(x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
	(x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
	(x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
	as modifiers.
	* xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.

1192 1193 1194 1195 1196
	* lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
	(XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
	Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
	presumably because the widths might not match.

1197 1198
	* window.c (size_window): Avoid needless test at loop start.

	* callproc.c (call_process_cleanup) [MSDOS]: Don't close and
	unlink the temporary file if Fcall_process didn't create it in the
	first place.
	(Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
	child process will be redirected to a file specified with `:file'.

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.

	* dbusbind.c (QCdbus_type_unix_fd): Declare static.
	(xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
	is a constant.
	(Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
	a string.  Handle both cases.
	(Fdbus_call_method_asynchronously, Fdbus_register_signal)
	(Fdbus_register_method): Use Qinvalid_function.

1288 1289 1290
	* term.c (vfatal): Remove stray call to va_end.
	It's not needed and the C Standard doesn't allow it here anyway.

	Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.

	* eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM

1307 1308 1309
	* charset.h (struct charset.code_space): Now has 15 elements, not 16.

	* lread.c (read_integer): Be more consistent with string-to-number.
	Use string_to_number to do the actual conversion; this avoids
	rounding errors and fixes some other screwups.  Without this fix,
	for example, #x1fffffffffffffff was misread as -2305843009213693952.

1322 1323 1324 1325
	* dispnew.c (scrolling_window): Return 1 if we scrolled,
	to match comment at start of function.  This also removes a
	GCC warning about overflow in a 32+64-bit port.

1326 1327
	* lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.

	Use SYMBOLP-guarded XSYMBOL, not XPNTR.
1333

1334 1335 1336
	* lisp.h (EMACS_INTPTR): Remove.  All uses changed to intptr_t.
	(EMACS_UINTPTR): Likewise, with uintptr_t.

1337 1338 1339 1340
	* 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.
1341 1342
	However, temporarily disable this change unless the temporary
	symbol WIDE_EMACS_INT is defined.
1343

1344 1345
	* lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.

1346 1347 1348 1349 1350 1351 1352 1353 1354 1355 1356 1357 1358 1359 1360 1361 1362 1363 1364 1365 1366 1367 1368 1369 1370 1371 1372 1373 1374 1375
	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.

1376 1377 1378 1379 1380 1381
	* 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.

1382 1383 1384 1385 1386 1387 1388 1389
	* 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.

1390 1391 1392 1393 1394
	* 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 *.

1395 1396
	* eval.c (Fautoload): Don't double-shift a pointer.

1397 1398
