3 * lisp.h (DEFINE_FUNC): Make sname 'static'.
5 Make Emacs functions such as Fatom 'static' by default.
6 This makes it easier for human readers (and static analyzers)
7 to see whether these functions can be called from other modules.
8 DEFUN now defines a static function. To make the function external
9 so that it can be used in other C modules, use the new macro DEFUE.
10 * lisp.h (DEFINE_FUNC): New macro, with the old contents of DEFUN.
11 (DEFUN): Rewrite in terms of DEFINE_FUNC. It now generates a
12 static function definition. Use DEFUE if you want an extern one.
13 (DEFUE, INFUN): New macros.
14 (Funibyte_char_to_multibyte, Fsyntax_table_p, Finit_image_library):
15 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
16 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
17 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
18 Remove decls, since these functions are now static.
19 (Funintern, Fget_internal_run_time): New decls, since these functions
20 were already external.
22 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
23 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
24 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
25 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
26 * keyboard.c, keymap.c, lread.c:
27 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
28 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
29 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
30 Mark functions with DEFUE instead of DEFUN,
31 if they are used in other modules.
32 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
33 decls for now-static functions.
34 * buffer.h (Fdelete_overlay): Remove decl.
35 * callproc.c (Fgetenv_internal): Mark as internal.
36 * composite.c (Fremove_list_of_text_properties): Remove decl.
37 (Fcomposition_get_gstring): New forward static decl.
38 * composite.h (Fcomposite_get_gstring): Remove decl.
39 * dired.c (Ffile_attributes): New forward static decl.
40 * doc.c (Fdocumntation_property): New forward static decl.
41 * eval.c (Ffetch_bytecode): New forward static decl.
42 (Funintern): Remove extern decl; now in .h file where it belongs.
43 * fileio.c (Fmake_symbolic_link): New forward static decl.
44 * image.c (Finit_image_library): New forward static decl.
45 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
46 * intervals.h (Fprevious_property_change):
47 (Fremove_list_of_text_properties): Remove decls.
48 * keyboard.c (Fthis_command_keys): Remove decl.
49 (Fcommand_execute): New forward static decl.
50 * keymap.c (Flookup_key): New forward static decl.
51 (Fcopy_keymap): Now static.
52 * keymap.h (Flookup_key): Remove decl.
53 * process.c (Fget_process): New forward static decl.
54 (Fprocess_datagram_address): Mark as internal.
55 * syntax.c (Fsyntax_table_p): New forward static decl.
56 (skip_chars): Remove duplicate decl.

60 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
61 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
63 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
65 * editfns.c (Fformat): Remove unreachable code.
67 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
69 Fix more problems found by GCC 4.6.0's static checks.
71 * xdisp.c (vmessage): Use a better test for character truncation.
73 * charset.c (load_charset_map): <, not <=, for optimization,
74 and to avoid potential problems with integer overflow.
75 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
76 * casetab.c (set_identity, shuffle): Likewise.
77 * editfns.c (Fformat): Likewise.
78 * syntax.c (skip_chars): Likewise.
80 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
81 This also lets GCC 4.6.0 generate slightly better loop code.
83 * callint.c (Fcall_interactively): <, not <=, for optimization.
84 (Fcall_interactively): Count the number of arguments produced,
85 not the number of arguments given. This is simpler and lets GCC
86 4.6.0 generate slightly better code.
88 * ftfont.c: Distingish more carefully between FcChar8 and char.
89 The previous code passed unsigned char * to a functions like
90 strlen and xstrcasecmp that expect char *, which does not
91 conform to the C standard.
92 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
93 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
94 char * when the C standard requires it.
96 * keyboard.c (read_char): Remove unused var.
98 * eval.c: Port to Windows vsnprintf (Bug#8435).
100 (SIZE_MAX): Define if the headers do not.
101 (verror): Do not give up if vsnprintf returns a negative count.
102 Instead, grow the buffer. This ports to Windows vsnprintf, which
103 does not conform to C99. Problem reported by Eli Zaretskii.
104 Also, simplify the allocation scheme, by avoiding the need for
105 calling realloc, and removing the ALLOCATED variable.
107 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
109 Remove invocations of doprnt, as Emacs now uses vsnprintf.
110 But keep the doprint source code for now, as we might revamp it
111 and use it again (Bug#8435).
112 * lisp.h (doprnt): Remove.
113 * Makefile.in (base_obj): Remove doprnt.o.
114 * deps.mk (doprnt.o): Remove.
116 error: Print 32- and 64-bit integers portably (Bug#8435).
117 Without this change, on typical 64-bit hosts error ("...%d...", N)
118 was used to print both 32- and 64-bit integers N, which relied on
120 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
122 * lisp.h (error, verror): Mark as printf-like functions.
123 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
124 Report overflow in size calculations when allocating printf buffer.
125 Do not truncate output string at its first null byte.
126 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
127 Truncate the output at a character boundary, since vsnprintf does not
129 * charset.c (check_iso_charset_parameter): Convert internal
130 character to string before calling 'error', since %c now has the
132 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
133 overflow when computing char to be passed to 'error'. Do not
134 pass Lisp_Object to 'error'; pass the integer instead.
135 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
136 formatted with plain %d.
138 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
140 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
142 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
144 * xterm.c (x_catch_errors): Remove duplicate declaration.
146 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
148 * xdisp.c, lisp.h (message_nolog): Remove; unused.
150 2011-04-10 Jim Meyering <meyering@redhat.com>
152 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
153 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
154 return ssize_t not "int", and use size_t as the buffer length.
155 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
156 * gnutls.h: Update declarations.
157 * process.c (read_process_output): Use ssize_t, to match.
158 (send_process): Likewise.
160 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
162 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
164 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
166 * ftfont.c (get_adstyle_property, ftfont_pattern_entity): Use
167 unsigned char, to match FcChar8 type definition.
169 * xterm.c (handle_one_xevent):
170 * xmenu.c (create_and_show_popup_menu):
171 * xselect.c (x_decline_selection_request)
172 (x_reply_selection_request): Avoid type-punned deref of X events.
174 2011-04-09 Eli Zaretskii <eliz@emacstest.gnu.org>
176 Fix some uses of `int' instead of EMACS_INT.
177 * search.c (string_match_1, fast_string_match)
178 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
179 (scan_buffer, find_next_newline_no_quit)
180 (find_before_next_newline, search_command, Freplace_match)
181 (Fmatch_data): Make some `int' variables be EMACS_INT.
183 * xdisp.c (display_count_lines): 3rd argument and return value now
184 EMACS_INT. All callers changed.
185 (pint2hrstr): Last argument is now EMACS_INT.
187 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
188 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
189 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
190 (decode_coding_utf_16, decode_coding_emacs_mule)
191 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
192 (decode_coding_ccl, decode_coding_charset)

199 (encode_designation_at_bol, encode_coding_iso_2022)
200 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
201 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
203 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.

231 (Qhelp_form_show): New var.
232 (syms_of_keyboard): Use DEFSYM macro.
234 * print.c (internal_with_output_to_temp_buffer): Function deleted.

268 to system-supplied API.
270 * eval.c (Fsignal): Remove excess argument to 'fatal'.
272 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
273 This avoids several warnings with gcc -Wstrict-overflow.
274 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
275 directly, rather than having caller test rule sign. This avoids
276 some unnecessary tests.
277 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
278 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
279 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

329 * eval.c (funcall_lambda): Rename local to avoid shadowing.
331 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
332 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
333 can always succeed if overflow has undefined behavior.
335 * search.c (boyer_moore, wordify): Remove vars set but not used.
336 (wordify): Omit three unnecessary tests.
338 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

361 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
363 * image.c (lookup_image): Remove var that is set but not used.
364 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
366 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
367 that are set but not used.
369 * xfns.c (make_invisible_cursor): Don't return garbage
370 if XCreateBitmapFromData fails (Bug#8410).
372 * xselect.c (x_get_local_selection, x_handle_property_notify):
373 Remove vars that are set but not used.
375 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
376 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
378 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:

394 (decode_coding_charset): Remove vars that are set but not used.
396 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
397 that is set but not used.
399 * print.c (print_object): Remove var that is set but not used.
401 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
402 The gnulib version avoids calling malloc in the usual case,
403 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
404 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
405 * filelock.c (current_lock_owner): Likewise.
406 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

430 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
431 and thereabouts. All callers changed.
432 (get_per_char_metric): Remove parameter `f', unused since
433 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

490 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
491 but without exporting it to Lisp.
493 * doc.c (Fdocumentation, store_function_docstring):
494 * data.c (Finteractive_form): Handle closures.
496 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
499 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN): New
501 (exec_byte_code): New function extracted from Fbyte_code to handle new
502 calling convention for byte-code-functions. Add new byte-codes.
504 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
506 * alloc.c (Fmake_symbol): Init new `declared_special' field.
508 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
510 * xdisp.c (redisplay_internal): Fix prototype.
512 2011-03-31 Eli Zaretskii <eliz@gnu.org>
514 * xdisp.c (SCROLL_LIMIT): New macro.
515 (try_scrolling): Use it when setting scroll_limit. Limit
516 scrolling to 100 screen lines.
517 (redisplay_window): Even when falling back on "recentering",
518 position point in the window according to scroll-conservatively,
519 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
521 (try_scrolling): When point is above the window, allow searching
522 as far as scroll_max, or one screenful, to compute vertical
523 distance from PT to the scroll margin position. This prevents
524 try_scrolling from unnecessarily failing when
525 scroll-conservatively is set to a value slightly larger than the
526 window height. Clean up the case of PT below the margin at bottom
527 of window: scroll_max can no longer be INT_MAX. When aggressive
528 scrolling is in use, don't let point enter the opposite scroll
529 margin as result of the scroll.
530 (syms_of_xdisp) <scroll-conservatively>: Document the
531 threshold of 100 lines for never-recentering scrolling.
533 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
535 * dispextern.h (move_it_by_lines):
536 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
537 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
538 (message_log_check_duplicate): Remove parameters `prev_bol' and
539 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
540 (redisplay_internal): Remove parameter `preserve_echo_area',
541 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
543 * indent.c (Fvertical_motion):
544 * window.c (window_scroll_pixel_based, Frecenter):
545 Don't pass `need_y_p' to `move_it_by_lines'.
547 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
549 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
550 steal a few bits to be more compact.
551 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
552 Remove unneeded casts.
554 * bytecode.c (Fbyte_code): CAR and CDR can GC.
556 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
558 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
559 binding" message (bug#7967).
561 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
563 Fix more problems found by GCC 4.6.0's static checks.
565 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
566 Remove unused local var.
568 * editfns.c (Fmessage_box): Remove unused local var.
570 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
571 (note_mode_line_or_margin_highlight, note_mouse_highlight):
572 Omit unused local vars.
573 * window.c (shrink_windows): Omit unused local var.
574 * menu.c (digest_single_submenu): Omit unused local var.
575 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
576 Omit unused local var.
578 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
579 Don't assume string length fits in int.
580 (keyremap_step, read_key_sequence): Use size_t for sizes.
581 (read_key_sequence): Don't check last_real_key_start redundantly.
583 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
584 instead of alloca (Bug#8344).
586 * eval.c (Fbacktrace): Don't assume nargs fits in int.
587 (Fbacktrace_frame): Don't assume nframes fits in int.
589 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
591 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
594 * term.c (produce_glyphless_glyph): Remove unnecessary test.
596 * cm.c (calccost): Turn while-do into do-while, for clarity.
598 * keyboard.c (syms_of_keyboard): Use the same style as later
599 in this function when indexing through an array. This also
600 works around GCC bug 48267.
602 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
604 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
606 * chartab.c (sub_char_table_ref_and_range): Redo for slight
607 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
609 * keyboard.c, keyboard.h (num_input_events): Now size_t.
610 This avoids undefined behavior on integer overflow, and is a bit
611 more convenient anyway since it is compared to a size_t variable.
613 Variadic C functions now count arguments with size_t, not int.
614 This avoids an unnecessary limitation on 64-bit machines, which
615 caused (substring ...) to crash on large vectors (Bug#8344).
616 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
617 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

620 * data.c (arith_driver, float_arith_driver): Likewise.
621 * editfns.c (general_insert_function): Likewise.
622 * eval.c (struct backtrace.nargs, interactive_p)
623 (internal_condition_case_n, run_hook_with_args, apply_lambda)
624 (funcall_lambda, mark_backtrace): Likewise.
625 * fns.c (concat): Likewise.
626 * frame.c (x_set_frame_parameters): Likewise.
627 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
628 0 if not found, not -1. All callers changed.
630 * alloc.c (garbage_collect): Don't assume stack size fits in int.
631 (stack_copy_size): Now size_t, not int.
632 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
634 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
636 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
637 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
640 * lisp.h (multibyte_char_to_unibyte):
641 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
642 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
643 * character.h (CHAR_TO_BYTE8):
644 * cmds.c (internal_self_insert):
645 * editfns.c (general_insert_function):
646 * keymap.c (push_key_description):
647 * search.c (Freplace_match):
648 * xdisp.c (message_dolog, set_message_1): All callers changed.
650 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
652 * keyboard.c (safe_run_hook_funcall): New function.
653 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
654 don't set the hook to nil, but remove the offending function instead.
655 (Qcommand_hook_internal): Remove, unused.
656 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
657 Vcommand_hook_internal.
659 * eval.c (enum run_hooks_condition): Remove.
660 (funcall_nil, funcall_not): New functions.
661 (run_hook_with_args): Call each function through a `funcall' argument.
662 Remove `cond' argument, now redundant.
663 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
664 (Frun_hook_with_args_until_failure): Adjust accordingly.
665 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

674 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
675 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
678 * w32.c (_wsa_errlist): Use braces for struct initializers.
680 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
681 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
683 (string_buffer_position): Likewise. Also, make static (it's never
684 used outside xdisp.c).
685 (cursor_row_p): Remove parameter `w', unused since
686 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.
687 (decode_mode_spec): Remove parameter `precision', introduced during
688 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
691 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

836 * callint.c (Fcall_interactively):
837 * buffer.c (Fkill_all_local_variables):
838 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
840 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
841 unconditionnaly since it does the check itself.
843 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
845 Fix more problems found by GCC 4.5.2's static checks.
847 * coding.c (encode_coding_raw_text): Avoid unnecessary test
848 the first time through the loop, since we know p0 < p1 then.
849 This also avoids a gcc -Wstrict-overflow warning.
851 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
852 leading to a memory leak, possible in functions like
853 load_charset_map_from_file that can allocate an unbounded number
854 of objects (Bug#8318).
856 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
857 that could (at least in theory) be that large.
859 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
860 This is less likely to overflow, and avoids undefined behavior if
861 overflow does occur. All callers changed. Use strtoul to scan
862 for the unsigned long integer.
863 (pint2hrstr): Simplify and tune code slightly.
864 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
866 * scroll.c (do_scrolling): Work around GCC bug 48228.
867 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

877 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
879 * process.c (Fmake_network_process): Use socklen_t, not int,
880 where POSIX says socklen_t is required in portable programs.
881 This fixes a porting bug on hosts like 64-bit HP-UX, where
882 socklen_t is wider than int (Bug#8277).
883 (Fmake_network_process, server_accept_connection):
884 (wait_reading_process_output, read_process_output):
887 * process.c: Rename or move locals to avoid shadowing.

892 (Fnetwork_interface_info): Fix pointer signedness.
893 (process_send_signal): Add cast to avoid pointer signedness problem.
894 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
895 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
897 Make tparam.h and terminfo.c consistent.
898 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
899 Include tparam.h instead, since it declares them.
900 * cm.h (PC): Remove extern decl; tparam.h now does this.
901 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
902 * terminfo.c: Include tparam.h, to check interfaces.
903 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
904 (tparam): Adjust signature to match interface in tparam.h;
905 this removes some undefined behavior. Check that outstring and len
906 are zero, which they always are with Emacs.
907 * tparam.h (PC, BC, UP): New extern decls.
909 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
910 (xftfont_open): Rename locals to avoid shadowing.
912 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
913 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
914 (OTF_TAG_SYM): Omit macro if not needed.
915 (ftfont_list): Remove unused local.
916 (get_adstyle_property, ftfont_pattern_entity):
917 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
918 Rename locals to avoid shadowing.
920 * xfont.c (xfont_list_family): Mark var as initialized.
922 * xml.c (make_dom): Now static.
924 * composite.c (composition_compute_stop_pos): Rename local to
926 (composition_reseat_it): Remove unused locals.
927 (find_automatic_composition, composition_adjust_point): Likewise.
928 (composition_update_it): Mark var as initialized.
929 (find_automatic_composition): Mark vars as initialized,
930 with a FIXME (Bug#8290).
932 character.h: Rename locals to avoid shadowing.
933 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
934 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
935 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
936 (BUF_DEC_POS): Be more systematic about renaming local temporaries
939 * textprop.c (property_change_between_p): Remove; unused.
941 * intervals.c (interval_start_pos): Now static.
943 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
945 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
946 Rename locals to avoid shadowing.
948 * sound.c (wav_play, au_play, Fplay_sound_internal):
949 Fix pointer signedness.
950 (alsa_choose_format): Remove unused local var.
951 (wav_play): Initialize a variable to 0, to prevent undefined
954 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
956 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
958 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
959 clobbering (Bug#8298).
960 * sysdep.c (sys_subshell): Likewise.
961 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
963 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
964 This should get cleaned up, so that child_setup has the
965 same signature on all platforms.
967 * callproc.c (call_process_cleanup): Now static.
968 (relocate_fd): Rename locals to avoid shadowing.

1137 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
1138 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
1139 to use the following functions instead of these macros.
1140 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
1141 EMACS_INT, since callers assume the returned value fits in int.
1142 (upcase1): Likewise, for UPCASE_TABLE.
1143 (uppercasep, lowercasep, upcase): New static inline functions.
1144 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

1154 (regex_compile, re_match_2_internal): Mark locals as initialized.
1155 (RETALLOC_IF): Define only if needed.
1156 (WORDCHAR_P): Likewise. This one is never needed, but is used
1157 only in a comment talking about a compiler bug, so put inside
1158 the #if 0 of that comment.
1159 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
1160 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
1163 * search.c (boyer_moore): Rename locals to avoid shadowing.

1186 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
1187 New macros, so that the caller can use some names other than
1188 gcpro1, gcpro2, etc.
1189 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
1191 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
1192 argument, for consistency with GCPRO2_VAR, etc: it is now the
1193 prefix of the variable, not the variable itself. All uses
1195 * dired.c (directory_files_internal, file_name_completion):
1196 Rename locals to avoid shadowing.
1198 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
1199 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
1200 dired.c's scmp function, had undefined behavior.
1201 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
1202 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
1203 * buffer.h: ... to here, because these macros use current_buffer,
1204 and the new implementation with inline functions needs to have
1205 current_buffer in scope now, rather than later when the macros
1207 (downcase, upcase1): New static inline functions.
1208 (DOWNCASE, UPCASE1): Reimplement using these functions.
1209 This avoids undefined behavior in expressions like
1210 DOWNCASE (x) == DOWNCASE (y), which previously suffered
1211 from race conditions in accessing the global variables
1212 case_temp1 and case_temp2.
1213 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
1214 * lisp.h (case_temp1, case_temp2): Remove their decls.
1215 * character.h (ASCII_CHAR_P): Move from here ...
1216 * lisp.h: ... to here, so that the inline functions mentioned
1219 * dired.c (directory_files_internal_unwind): Now static.
1221 * fileio.c (file_name_as_directory, directory_file_name):
1222 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
1224 (file_name_as_directory): Use const pointers when appropriate.
1225 (Fexpand_file_name): Likewise. In particular, newdir might
1226 point at constant storage, so make it a const pointer.
1227 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
1228 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
1230 (Fset_file_times, Finsert_file_contents, auto_save_error):
1231 Rename locals to avoid shadowing.

1237 * marker.c (bytepos_to_charpos): Remove; unused.
1239 * lisp.h (verify_bytepos, count_markers): New decls,
1240 so that gcc does not warn that these functions aren't declared.
1242 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
1243 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
1244 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
1245 (copy_text): Remove unused local var.
1247 * filelock.c (within_one_second): Now static.
1248 (lock_file_1): Rename local to avoid shadowing.
1250 * buffer.c (fix_overlays_before): Mark locals as initialized.
1251 (fix_start_end_in_overlays): Likewise. This function should be
1252 simplified by using pointers-to-pointers, but that's a different
1254 (switch_to_buffer_1): Now static.
1255 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
1256 (report_overlay_modification): Rename locals to avoid shadowing.
1258 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
1259 Fix pointer signedness issue.
1260 (sys_subshell): Mark local as volatile if checking for lint,
1261 to suppress a gcc -Wclobbered warning that does not seem to be right.
1262 (MAXPATHLEN): Define only if needed.
1264 * process.c (serial_open, serial_configure): Move decls from here ...
1265 * systty.h: ... to here, so that they can be checked.
1267 * fns.c (get_random, seed_random): Move extern decls from here ...
1268 * lisp.h: ... to here, so that they can be checked.
1270 * sysdep.c (reset_io): Now static.
1271 (wait_for_termination_signal): Remove; unused.
1273 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
1274 (copy_keymap_item, append_key, push_text_char_description):
1276 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
1277 (DENSE_TABLE_SIZE): Remove; unused.

1279 (describe_map_tree):
1280 Rename locals to avoid shadowing.
1282 * keyboard.c: Declare functions static if they are not used elsewhere.
1283 (echo_char, echo_dash, cmd_error, top_level_2):
1284 (poll_for_input, handle_async_input): Now static.
1285 (read_char, kbd_buffer_get_event, make_lispy_position):
1286 (make_lispy_event, make_lispy_movement, apply_modifiers):

1430 1152921504606846976) returns the obviously-bogus value (-948597
1431 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
1432 reports time overflow. See
1433 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
