3 Fix more problems found by GCC 4.6.0's static checks.
5 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
7 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
9 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
11 * xdisp.c (vmessage): Mark as a printf-like function.
13 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
15 * sound.c (sound_warning): Don't crash if arg contains a printf format.
17 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
18 printf-like functions.
19 (tiff_load): Add casts to remove these marks before passing them
20 to system-supplied API.
22 * eval.c (Fsignal): Remove excess argument to 'fatal'.
24 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
25 This avoids several warnings with gcc -Wstrict-overflow.
26 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
27 directly, rather than having caller test rule sign. This avoids
28 some unnecessary tests.
29 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
30 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
31 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
33 * xfont.c (xfont_text_extents): Remove var that was set but not used.
34 (xfont_open): Avoid unnecessary tests.
36 * composite.c (composition_gstring_put_cache): Use unsigned integer.
38 * composite.h, composite.c (composition_gstring_put_cache):
39 Use EMACS_INT, not int, for length.
41 * composite.h (COMPOSITION_DECODE_REFS): New macro,
42 breaking out part of COMPOSITION_DECODE_RULE.
43 (COMPOSITION_DECODE_RULE): Use it.
44 * composite.c (get_composition_id): Remove unused local vars,
45 by using the new macro.
47 * textprop.c (set_text_properties_1): Change while to do-while,
48 since the condition is always true at first.
50 * intervals.c (graft_intervals_into_buffer): Mark var as used.
51 (interval_deletion_adjustment): Return unsigned value.
54 * process.c (list_processes_1, create_pty, read_process_output):
55 (exec_sentinel): Remove vars that were set but not used.
56 (create_pty): Remove unnecessary "volatile"s.
57 (Fnetwork_interface_info): Avoid possibility of int overflow.
58 (read_process_output): Do adaptive read buffering even if carryover.
59 (read_process_output): Simplify nbytes computation if buffered.
61 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
63 * syntax.c (scan_words): Remove var that was set but not used.
64 (update_syntax_table): Use unsigned instead of int.
66 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
67 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
68 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
70 * print.c (print_error_message): Avoid int overflow.
72 * font.c (font_list_entities): Redo for clarity,
73 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
75 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
76 (font_score): Avoid potential overflow in diff calculation.
78 * fns.c (substring_both): Remove var that is set but not used.
79 (sxhash): Redo loop for clarity and to avoid wraparound warning.
81 * eval.c (funcall_lambda): Rename local to avoid shadowing.
83 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
84 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
85 can always succeed if overflow has undefined behavior.
87 * search.c (boyer_moore, wordify): Remove vars set but not used.
88 (wordify): Omit three unnecessary tests.
90 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
91 All callers changed. This avoids the need for an unused var.
93 * casefiddle.c (casify_region): Remove var that is set but not used.
95 * dired.c (file_name_completion): Remove var that is set but not used.
97 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
99 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.

111 (timer_check_2): Mark vars as initialized.
113 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
115 * image.c (lookup_image): Remove var that is set but not used.
116 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
118 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
119 that are set but not used.
121 * xfns.c (make_invisible_cursor): Don't return garbage
122 if XCreateBitmapFromData fails (Bug#8410).
124 * xselect.c (x_get_local_selection, x_handle_property_notify):
125 Remove vars that are set but not used.
127 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
128 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
130 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
131 Remove var that is set but not used.

133 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
136 * xfaces.c (realize_named_face): Remove vars that are set but not used.
137 (map_tty_color) [!defined MSDOS]: Likewise.
139 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
141 * coding.c: Remove vars that are set but not used.
142 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
144 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
145 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
146 (decode_coding_charset): Remove vars that are set but not used.
148 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
149 that is set but not used.
151 * print.c (print_object): Remove var that is set but not used.
153 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
154 The gnulib version avoids calling malloc in the usual case,
155 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
156 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
157 * filelock.c (current_lock_owner): Likewise.
158 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

162 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
163 ../lib/careadlinkat.h.
165 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
167 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
168 first non-nil return value).
170 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
172 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
173 if not defined (Bug#8403).
175 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
177 * xdisp.c (display_count_lines): Remove parameter `start',
178 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

180 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
181 (fill_stretch_glyph_string): Remove parameters `row' and `area',
182 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
183 and thereabouts. All callers changed.
184 (get_per_char_metric): Remove parameter `f', unused since
185 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

197 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
199 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
202 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
206 * window.c (Ftemp_output_buffer_show): New fun.
207 (Fsave_window_excursion):
208 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
210 * lread.c (lisp_file_lexically_bound_p): New function.
211 (Fload): Bind Qlexical_binding.

213 Bind Qinternal_interpreter_environment.
214 (Feval_buffer): Bind Qlexical_binding.
215 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
217 (syms_of_lread): Declare `lexical-binding'.
219 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
221 * keyboard.c (eval_dyn): New fun.
222 (menu_item_eval_property): Use it.
224 * image.c (parse_image_spec): Use Ffunctionp.
226 * fns.c (concat, mapcar1): Accept byte-code-functions.
228 * eval.c (Fsetq): Handle lexical vars.
229 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
230 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
231 (FletX, Flet): Obey lexical binding.
232 (Fcommandp): Handle closures.
233 (Feval): New `lexical' arg.
234 (eval_sub): New function extracted from Feval. Use it almost
235 everywhere where Feval was used. Look up vars in lexical env.
237 (Ffunctionp): Move from subr.el.
238 (Ffuncall): Handle closures.
239 (apply_lambda): Remove `eval_flags'.
240 (funcall_lambda): Handle closures and new byte-code-functions.
241 (Fspecial_variable_p): New function.
242 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
243 but without exporting it to Lisp.
245 * doc.c (Fdocumentation, store_function_docstring):
246 * data.c (Finteractive_form): Handle closures.
248 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
251 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN): New
253 (exec_byte_code): New function extracted from Fbyte_code to handle new

262 * xdisp.c (redisplay_internal): Fix prototype.
264 2011-03-31 Eli Zaretskii <eliz@gnu.org>
266 * xdisp.c (SCROLL_LIMIT): New macro.
267 (try_scrolling): Use it when setting scroll_limit. Limit
268 scrolling to 100 screen lines.
269 (redisplay_window): Even when falling back on "recentering",
270 position point in the window according to scroll-conservatively,
271 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
273 (try_scrolling): When point is above the window, allow searching
274 as far as scroll_max, or one screenful, to compute vertical
275 distance from PT to the scroll margin position. This prevents
276 try_scrolling from unnecessarily failing when
277 scroll-conservatively is set to a value slightly larger than the
278 window height. Clean up the case of PT below the margin at bottom
279 of window: scroll_max can no longer be INT_MAX. When aggressive
280 scrolling is in use, don't let point enter the opposite scroll
281 margin as result of the scroll.
282 (syms_of_xdisp) <scroll-conservatively>: Document the
283 threshold of 100 lines for never-recentering scrolling.
285 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

290 (message_log_check_duplicate): Remove parameters `prev_bol' and
291 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
292 (redisplay_internal): Remove parameter `preserve_echo_area',
293 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
295 * indent.c (Fvertical_motion):
296 * window.c (window_scroll_pixel_based, Frecenter):
297 Don't pass `need_y_p' to `move_it_by_lines'.
299 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
301 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
302 steal a few bits to be more compact.
303 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
304 Remove unneeded casts.
306 * bytecode.c (Fbyte_code): CAR and CDR can GC.
308 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
310 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
311 binding" message (bug#7967).
313 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
315 Fix more problems found by GCC 4.6.0's static checks.
317 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
318 Remove unused local var.
320 * editfns.c (Fmessage_box): Remove unused local var.
322 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
323 (note_mode_line_or_margin_highlight, note_mouse_highlight):
324 Omit unused local vars.
325 * window.c (shrink_windows): Omit unused local var.
326 * menu.c (digest_single_submenu): Omit unused local var.
327 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
328 Omit unused local var.
330 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
331 Don't assume string length fits in int.
332 (keyremap_step, read_key_sequence): Use size_t for sizes.
333 (read_key_sequence): Don't check last_real_key_start redundantly.
335 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
336 instead of alloca (Bug#8344).
338 * eval.c (Fbacktrace): Don't assume nargs fits in int.
339 (Fbacktrace_frame): Don't assume nframes fits in int.
341 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
343 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
346 * term.c (produce_glyphless_glyph): Remove unnecessary test.
348 * cm.c (calccost): Turn while-do into do-while, for clarity.
350 * keyboard.c (syms_of_keyboard): Use the same style as later
351 in this function when indexing through an array. This also
352 works around GCC bug 48267.
354 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
356 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
358 * chartab.c (sub_char_table_ref_and_range): Redo for slight
359 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
361 * keyboard.c, keyboard.h (num_input_events): Now size_t.
362 This avoids undefined behavior on integer overflow, and is a bit
363 more convenient anyway since it is compared to a size_t variable.
365 Variadic C functions now count arguments with size_t, not int.
366 This avoids an unnecessary limitation on 64-bit machines, which
367 caused (substring ...) to crash on large vectors (Bug#8344).
368 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
369 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

377 * fns.c (concat): Likewise.
378 * frame.c (x_set_frame_parameters): Likewise.
379 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
380 0 if not found, not -1. All callers changed.
382 * alloc.c (garbage_collect): Don't assume stack size fits in int.
383 (stack_copy_size): Now size_t, not int.
384 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
386 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
388 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
389 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
392 * lisp.h (multibyte_char_to_unibyte):
393 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
394 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
395 * character.h (CHAR_TO_BYTE8):
396 * cmds.c (internal_self_insert):
397 * editfns.c (general_insert_function):
398 * keymap.c (push_key_description):
399 * search.c (Freplace_match):
400 * xdisp.c (message_dolog, set_message_1): All callers changed.
402 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
404 * keyboard.c (safe_run_hook_funcall): New function.
405 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
406 don't set the hook to nil, but remove the offending function instead.
407 (Qcommand_hook_internal): Remove, unused.
408 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
409 Vcommand_hook_internal.
411 * eval.c (enum run_hooks_condition): Remove.
412 (funcall_nil, funcall_not): New functions.
413 (run_hook_with_args): Call each function through a `funcall' argument.
414 Remove `cond' argument, now redundant.

427 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
430 * w32.c (_wsa_errlist): Use braces for struct initializers.
432 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
433 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
435 (string_buffer_position): Likewise. Also, make static (it's never
436 used outside xdisp.c).
437 (cursor_row_p): Remove parameter `w', unused since
438 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.
439 (decode_mode_spec): Remove parameter `precision', introduced during
440 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.

579 * term.c (Fsuspend_tty, Fresume_tty):
580 * minibuf.c (read_minibuf, run_exit_minibuf_hook):

589 * buffer.c (Fkill_all_local_variables):
590 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
592 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
593 unconditionnaly since it does the check itself.
595 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
597 Fix more problems found by GCC 4.5.2's static checks.
599 * coding.c (encode_coding_raw_text): Avoid unnecessary test
600 the first time through the loop, since we know p0 < p1 then.
601 This also avoids a gcc -Wstrict-overflow warning.
603 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
604 leading to a memory leak, possible in functions like
605 load_charset_map_from_file that can allocate an unbounded number
606 of objects (Bug#8318).
608 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
609 that could (at least in theory) be that large.
611 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
612 This is less likely to overflow, and avoids undefined behavior if
613 overflow does occur. All callers changed. Use strtoul to scan
614 for the unsigned long integer.
615 (pint2hrstr): Simplify and tune code slightly.
616 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
618 * scroll.c (do_scrolling): Work around GCC bug 48228.
619 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

624 This also avoids a warning with gcc -Wstrict-overflow.
626 * fileio.c (Fcopy_file): Report error if fchown or fchmod
629 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
631 * process.c (Fmake_network_process): Use socklen_t, not int,
632 where POSIX says socklen_t is required in portable programs.
633 This fixes a porting bug on hosts like 64-bit HP-UX, where
634 socklen_t is wider than int (Bug#8277).
635 (Fmake_network_process, server_accept_connection):
636 (wait_reading_process_output, read_process_output):

649 Make tparam.h and terminfo.c consistent.
650 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
651 Include tparam.h instead, since it declares them.
652 * cm.h (PC): Remove extern decl; tparam.h now does this.
653 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
654 * terminfo.c: Include tparam.h, to check interfaces.
655 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
656 (tparam): Adjust signature to match interface in tparam.h;
657 this removes some undefined behavior. Check that outstring and len
658 are zero, which they always are with Emacs.
659 * tparam.h (PC, BC, UP): New extern decls.
661 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
662 (xftfont_open): Rename locals to avoid shadowing.

682 with a FIXME (Bug#8290).
684 character.h: Rename locals to avoid shadowing.
685 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
686 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
687 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
688 (BUF_DEC_POS): Be more systematic about renaming local temporaries
691 * textprop.c (property_change_between_p): Remove; unused.
693 * intervals.c (interval_start_pos): Now static.
695 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
697 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
698 Rename locals to avoid shadowing.
700 * sound.c (wav_play, au_play, Fplay_sound_internal):
701 Fix pointer signedness.
702 (alsa_choose_format): Remove unused local var.
703 (wav_play): Initialize a variable to 0, to prevent undefined
706 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
708 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
710 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
711 clobbering (Bug#8298).
712 * sysdep.c (sys_subshell): Likewise.
713 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
715 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
716 This should get cleaned up, so that child_setup has the
717 same signature on all platforms.
719 * callproc.c (call_process_cleanup): Now static.
720 (relocate_fd): Rename locals to avoid shadowing.
722 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
724 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
725 not to be necessary, and produces flickering.
727 2011-03-20 Glenn Morris <rgm@gnu.org>
729 * config.in: Remove file.
731 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
733 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
734 are now in src/globals.h.
735 (syms_of_minibuf): Remove spurious & from previous change.
737 2011-03-20 Leo <sdl.web@gmail.com>
739 * minibuf.c (completing-read-function): New variable.

752 2011-03-17 Eli Zaretskii <eliz@gnu.org>
754 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
756 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>
758 Fix more problems found by GCC 4.5.2's static checks.
760 * process.c (make_serial_process_unwind, send_process_trap):
761 (sigchld_handler): Now static.
763 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
764 That way, the code declares only the vars that it needs.
765 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
766 * s/cygwin.h (PTY_ITERATION): Likewise.
767 * s/darwin.h (PTY_ITERATION): Likewise.
768 * s/gnu-linux.h (PTY_ITERATION): Likewise.
770 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
771 * process.c (allocate_pty): Don't declare stb unless it's needed.
773 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
774 (CONSTANTLIM): Remove; unused.
775 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
776 Define only if needed.
778 * unexelf.c (unexec): Name an expression,
779 to avoid gcc -Wbad-function-cast warning.
780 Use a different way to cause a compilation error if anyone uses
781 n rather than nn, a way that does not involve shadowing.
782 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
784 * deps.mk (unexalpha.o): Remove; unused.
786 New file unexec.h, the (simple) interface for unexec (Bug#8267).
787 * unexec.h: New file.
788 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
789 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
791 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
792 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
793 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
794 Change as necessary to match prototype in unexec.h.
796 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid

806 * print.c (Fredirect_debugging_output): Fix pointer signedess.
808 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
809 warning when compiling print.c.
811 * font.c (font_unparse_fcname): Abort in an "impossible" situation
812 instead of using an uninitialized var.
813 (font_sort_entities): Mark var as initialized.
815 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
817 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

850 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
851 some of which prompt warnings from gcc -Wbad-function-cast.
852 (Fformat_time_string, Fencode_time, Finsert_char):
853 (Ftranslate_region_internal, Fformat):
854 Rename or remove local vars to avoid shadowing.

872 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
873 Rename locals to avoid shadowing.
874 (mark_stack): Move local variables into the #ifdef region where
876 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if

881 (Fmemory_limit): Cast sbrk's returned value to char *.
883 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
884 avoids undefined behavior in theory.
886 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
888 Use functions, not macros, for up- and down-casing (Bug#8254).
889 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
890 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
891 to use the following functions instead of these macros.
892 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
893 EMACS_INT, since callers assume the returned value fits in int.
894 (upcase1): Likewise, for UPCASE_TABLE.
895 (uppercasep, lowercasep, upcase): New static inline functions.
896 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
897 the race-condition problem in the old DOWNCASE.
899 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
900 Rename locals to avoid shadowing.
901 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
902 (regex_compile, re_search_2, re_match_2_internal):
903 Remove unused local vars.
904 (FREE_VAR): Rewrite so as not to use empty "else",
905 which gcc can warn about.
906 (regex_compile, re_match_2_internal): Mark locals as initialized.
907 (RETALLOC_IF): Define only if needed.
908 (WORDCHAR_P): Likewise. This one is never needed, but is used
909 only in a comment talking about a compiler bug, so put inside
910 the #if 0 of that comment.
911 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
912 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
915 * search.c (boyer_moore): Rename locals to avoid shadowing.
916 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

934 (casify_region): Mark local as initialized.
936 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
938 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
939 New macros, so that the caller can use some names other than
941 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
943 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
944 argument, for consistency with GCPRO2_VAR, etc: it is now the
945 prefix of the variable, not the variable itself. All uses
947 * dired.c (directory_files_internal, file_name_completion):
948 Rename locals to avoid shadowing.
950 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
951 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
952 dired.c's scmp function, had undefined behavior.
953 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
954 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
955 * buffer.h: ... to here, because these macros use current_buffer,
956 and the new implementation with inline functions needs to have
957 current_buffer in scope now, rather than later when the macros
959 (downcase, upcase1): New static inline functions.
960 (DOWNCASE, UPCASE1): Reimplement using these functions.
961 This avoids undefined behavior in expressions like
962 DOWNCASE (x) == DOWNCASE (y), which previously suffered
963 from race conditions in accessing the global variables
964 case_temp1 and case_temp2.
965 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
966 * lisp.h (case_temp1, case_temp2): Remove their decls.
967 * character.h (ASCII_CHAR_P): Move from here ...
968 * lisp.h: ... to here, so that the inline functions mentioned
971 * dired.c (directory_files_internal_unwind): Now static.
973 * fileio.c (file_name_as_directory, directory_file_name):
974 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
976 (file_name_as_directory): Use const pointers when appropriate.
977 (Fexpand_file_name): Likewise. In particular, newdir might
978 point at constant storage, so make it a const pointer.
979 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
980 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
982 (Fset_file_times, Finsert_file_contents, auto_save_error):
983 Rename locals to avoid shadowing.
985 * minibuf.c (choose_minibuf_frame_1): Now static.
986 (Ftry_completion, Fall_completions): Rename or remove locals
989 * marker.c (bytepos_to_charpos): Remove; unused.
