	* lisp.h: Fix a problem with aliasing and vector headers.  (Bug#8546)
115 116 117 118 119 120 121
	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

122
	vectorlike_header that documents the constraints on layout of vectors
123 124 125
	and pseudovectors, and helps optimizing compilers not get fooled
	by Emacs's type punning.  It also adds the macros XSETTYPED_PVECTYPE
	XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.

126 127
	* lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
	the size member.
128 129 130 131 132
	(XSETPVECTYPE): Rewrite in terms of new macro.
	(XSETPVECTYPESIZE): New macro, specifying both type and size.
	This is a bit clearer, and further avoids the possibility of
	undesirable aliasing.
	(XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
Paul Eggert's avatar
Paul Eggert committed
133
	(XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
134 135
	(XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
	since Lisp_Subr is a special case (no "next" field).

Paul Eggert committed
136 137 138 139
	(ASIZE): Now uses header.size rather than size.  All
	previous uses of XVECTOR (foo)->size replaced to use this macro,
	to avoid the hassle of writing XVECTOR (foo)->header.size.
	(struct vectorlike_header): New type.
140 141 142 143 144 145 146
	(TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
	object, to help avoid aliasing.
	(PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
	(SUBRP): Likewise, since Lisp_Subr is a special case.
	* lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
	(struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
	(struct Lisp_Hash_Table): Combine first two members into a single

	changed to be "header.size" and "header.next".
	* buffer.h (struct buffer): Likewise.
	* font.h (struct font_spec, struct font_entity, struct font): Likewise.
	* frame.h (struct frame): Likewise.
	* process.h (struct Lisp_Process): Likewise.

	* window.h (struct window): Likewise.
	* alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
	Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
	* buffer.c (init_buffer_once): Likewise.
	* lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
	special case.
	* process.c (Fformat_network_address): Use local var for size,
	for brevity.

	Make the Lisp reader and string-to-float more consistent (Bug#8525)
167 168 169 170 171 172 173 174 175 176
	* 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.
177
	* lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
178
	(read1): Do not accept +. and -. as integers; this
179 180 181 182 183 184 185 186 187 188 189 190 191
	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
192
	no longer mishandles examples like "1.0e+".  Use strtoumax,
193 194
	so that overflow for non-base-10 numbers is reported only when
	there's no portable and simple way to convert to floating point.
195

196 197 198
	* textprop.c (set_text_properties_1): Rewrite for clarity,
	and to avoid GCC warning about integer overflow.

199 200 201 202 203 204
	* intervals.h (struct interval): Use EMACS_INT for members
	where EMACS_UINT might cause problems.  See
	<http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
	(CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
	* intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
	All uses changed.
205 206
	(offset_intervals): Tell GCC not to worry about length overflow
	when negating a negative length.
207

208 209 210
	* alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
	(overrun_check_free): Likewise.

211 212 213 214
	* alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
	in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
	word size.

215 216 217 218 219 220
	* gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
	(gnutls_make_error): Rename local to avoid shadowing.
	(gnutls_emacs_global_deinit): ifdef out; not used.
	(Fgnutls_boot): Use const for pointer to readonly storage.
	Comment out unused local.  Fix pointer signedness problems.

221 222 223 224
	* 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.

225 226 227 228 229
	* gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
	(GDK_KEY_g): Don't define if already defined.
	(xg_prepare_tooltip): Avoid pointer signedness problem.
	(xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.

230 231 232
	* process.c (Fnetwork_interface_info): Avoid left-shift undefined
	behavior with 1 << 31.  GCC 4.6.0 warns about this on 32-bit hosts.

233 234 235 236
	* xfns.c (Fx_window_property): Simplify a bit,
	to make a bit faster and to avoid GCC 4.6.0 warning.
	* xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.

237 238
	* fns.c (internal_equal): Don't assume size_t fits in int.

239 240
	* alloc.c (compact_small_strings): Tighten assertion a little.

241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258
	Replace pEd with more-general pI, and fix some printf arg casts.
	* lisp.h (pI): New macro, generalizing old pEd macro to other
	conversion specifiers.  For example, use "...%"pI"d..." rather
	than "...%"pEd"...".
	(pEd): Remove.  All uses replaced with similar uses of pI.
	* src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
	* alloc.c (check_pure_size): Don't overflow by converting size to int.
	* bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
	* data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
	* dbusbind.c (xd_append_arg): Use pI to avoid cast.
	(Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
	* font.c (font_unparse_xlfd): Avoid potential buffer overrun on
	64-bit hosts.
	(font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
	* keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
	* print.c (safe_debug_print, print_object): Likewise.
	(print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
	to int.
259 260
	Use pI instead of if-then-else-abort.  Use %p to avoid casts,
	avoiding the 0 flag, which is not portable.
261 262 263 264 265
	* process.c (Fmake_network_process): Use pI to avoid cast.
	* region-cache.c (pp_cache): Likewise.
	* xdisp.c (decode_mode_spec): Likewise.
	* xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
	behavior on 64-bit hosts with printf arg.
266
	* xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
267 268 269
	(x_stop_queuing_selection_requests): Likewise.
	(x_get_window_property): Don't truncate byte count to an 'int'
	when tracing.
270

271 272 273 274 275
	* 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.

276 277 278 279 280 281 282 283 284
	* alloc.c: Remove unportable assumptions about struct layout.
	(SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
	(SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
	(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.

285 286
	* alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
	This doesn't fix a bug but makes the code clearer.
287 288
	(string_overrun_cookie): Now const.  Use initializers that
	don't formally overflow signed char, to avoid warnings.
289 290
	(allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
	can cause Emacs to crash when string overrun checking is enabled.
291 292 293
	(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).
294
	(check_sblock, check_string_bytes, check_string_free_list): Protoize.

	Improve doprnt and its use in verror.  (Bug#8545)

	supported by the function.  Use SAFE_ALLOCA instead of always
	using `alloca'.

	* eval.c (verror): Don't limit the buffer size at size_max-1, that
	is one byte too soon.  Don't use xrealloc; instead xfree and

	* sysdep.c (emacs_write, emacs_read): Use ssize_t for last
	argument, local variables, and return value.

1175 1176
	* xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.

1177 1178
	Fix more problems found by GCC 4.6.0's static checks.

1179 1180
	* xdisp.c (vmessage): Use a better test for character truncation.

1181 1182
	* charset.c (load_charset_map): <, not <=, for optimization,
	and to avoid potential problems with integer overflow.
1183
	* chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
1184
	* casetab.c (set_identity, shuffle): Likewise.

	* syntax.c (skip_chars): Likewise.
1187

1188 1189 1190
	* xmenu.c (set_frame_menubar): Allocate smaller local vectors.
	This also lets GCC 4.6.0 generate slightly better loop code.

1191 1192 1193 1194 1195
	* callint.c (Fcall_interactively): <, not <=, for optimization.
	(Fcall_interactively): Count the number of arguments produced,
	not the number of arguments given.  This is simpler and lets GCC
	4.6.0 generate slightly better code.

1196 1197 1198 1199 1200 1201 1202 1203
	* ftfont.c: Distingish more carefully between FcChar8 and char.
	The previous code passed unsigned char * to a functions like
	strlen and xstrcasecmp that expect char *, which does not
	conform to the C standard.
	(get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
	arguments to FcPatternGetString, and explicitly cast FcChar8 * to
	char * when the C standard requires it.

1204 1205
	* keyboard.c (read_char): Remove unused var.

1206 1207 1208 1209 1210 1211 1212 1213 1214
	* eval.c: Port to Windows vsnprintf (Bug#8435).
	Include <limits.h>.
	(SIZE_MAX): Define if the headers do not.
	(verror): Do not give up if vsnprintf returns a negative count.
	Instead, grow the buffer.  This ports to Windows vsnprintf, which
	does not conform to C99.  Problem reported by Eli Zaretskii.
	Also, simplify the allocation scheme, by avoiding the need for
	calling realloc, and removing the ALLOCATED variable.

1215 1216
	* eval.c (verror): Initial buffer size is 4000 (not 200) bytes.

1217 1218 1219
	Remove invocations of doprnt, as Emacs now uses vsnprintf.
	But keep the doprint source code for now, as we might revamp it
	and use it again (Bug#8435).
1220 1221 1222 1223
	* lisp.h (doprnt): Remove.
	* Makefile.in (base_obj): Remove doprnt.o.
	* deps.mk (doprnt.o): Remove.

1224 1225 1226 1227 1228 1229 1230 1231 1232 1233 1234 1235 1236 1237 1238 1239 1240 1241 1242 1243 1244 1245
	error: Print 32- and 64-bit integers portably (Bug#8435).
	Without this change, on typical 64-bit hosts error ("...%d...", N)
	was used to print both 32- and 64-bit integers N, which relied on
	undefined behavior.
	* lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
	New macro.
	* lisp.h (error, verror): Mark as printf-like functions.
	* eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
	Report overflow in size calculations when allocating printf buffer.
	Do not truncate output string at its first null byte.
	* xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
	Truncate the output at a character boundary, since vsnprintf does not
	do that.
	* charset.c (check_iso_charset_parameter): Convert internal
	character to string before calling 'error', since %c now has the
	printf meaning.
	* coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
	overflow when computing char to be passed to 'error'.  Do not
	pass Lisp_Object to 'error'; pass the integer instead.
	* nsfns.m (Fns_do_applescript): Use int, not long, since it's
	formatted with plain %d.

1246 1247
	* eval.c (internal_lisp_condition_case): Don't pass spurious arg.

1248 1249
	* keyboard.c (access_keymap_keyremap): Print func name, not garbage.

1250 1251
	* coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.

1252 1253
	* xterm.c (x_catch_errors): Remove duplicate declaration.

1254 1255
	* term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.

1256 1257
	* xdisp.c, lisp.h (message_nolog): Remove; unused.

	use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
	* gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
	return ssize_t not "int", and use size_t as the buffer length.
	(emacs_gnutls_write): Likewise, and make the buffer pointer "const".
	* gnutls.h: Update declarations.
	* process.c (read_process_output): Use ssize_t, to match.
	(send_process): Likewise.
