* | Limit <config.h>’s includesPaul Eggert2016-09-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This follows up on recent problems with the fact that config.h includes stdlib.h etc.; some files need to include stdlib.h later. config.h generally should limit itself to includes that are universally safe; outside of MS-Windows, only stdbool.h makes the cut among the files currently included. So, move the other includes to just the files that need them (Bug#24506). * configure.ac (config_opsysfile): Remove, as this generic hook is no longer needed. * lib-src/etags.c, src/unexmacosx.c, src/w32.c, src/w32notify.c: * src/w32proc.c (_GNU_SOURCE): Remove, as it’s OK for config.h to do this now. * src/conf_post.h: Include <ms-w32.h>, instead of the generic config_opsysfile, for simplicity as this old way of configuring is now done only for the MS-Windows port. Do not include <ms-w32.h> if DEFER_MS_W32_H, for the benefit of the few files that want its effects later. Do not include <alloca.h>, <string.h>, or <stdlib.h>. Other files modified to include these headers as needed, or to not include headers that are no longer needed. * src/lisp.h: Include <alloca.h> and <string.h> here, since some of the inline functions need them. * src/regex.c: Include <alloca.h> if not emacs. (If emacs, we can rely on SAFE_ALLOCA.) There is no longer any need to worry about HAVE_ALLOCA_H. * src/unexmacosx.c: Rely on config.h not including stdlib.h. * src/w32.c, src/w32notify.c, src/w32proc.c (DEFER_MS_W32_H): Define before including <config.h> first, and include <ms-w32.h> after the troublesome headers.

(check_window_system): Declare as _Noreturn. (Ficonify_frame): (Fset_frame_position): Don’t declare and set 'f'. * src/frame.h [!HAVE_WINDOW_SYSTEM] (decode_window_system_frame) (check_window_system): Add _Noreturn prototypes. (FRAME_FRINGE_COLS, FRAME_TOTAL_FRINGE_WIDTH) (FRAME_LEFT_FRINGE_WIDTH, FRAME_RIGHT_FRINGE_WIDTH) (FRAME_INTERNAL_BORDER_WIDTH, FRAME_RIGHT_DIVIDER_WIDTH) (FRAME_BOTTOM_DIVIDER_WIDTH): Explicitly discard unused argument. * src/xdisp.c (handle_single_display_spec): Declare 'fringe_bitmap' only if HAVE_WINDOW_SYSTEM.

Remove redundant #ifdef.
* | Replace IF_LINT by NONVOLATILE and UNINITPaul Eggert2016-06-081-1/+2
| | | | | | | | | | | | | | Inspired by a suggestion from RMS in: http://bugs.gnu.org/23640#58 * .dir-locals.el (c-mode): Adjust to macro changes. * src/conf_post.h (NONVOLATILE, UNINIT): New macros (Bug#23640). (IF_LINT): Remove. All uses replaced by the new macros.
* | New C macro AUTO_STRING_WITH_LENPaul Eggert2016-04-041-1/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | Put a bit less pressure on the garbage collector by defining a macro that is like AUTO_STRING but also allows null bytes in strings, and by extending AUTO_STRING to work with any unibyte string. * src/alloc.c (verify_ascii): Remove; all uses removed. AUTO_STRING can now be used on non-ASCII unibyte strings. * src/lisp.h (AUTO_STRING): Now allows non-ASCII unibyte strings. (AUTO_STRING_WITH_LEN): New macro. * src/coding.c (from_unicode_buffer): * src/editfns.c (format_time_string): * src/emacs-module.c (module_make_string, module_format_fun_env): * src/fileio.c (Fexpand_file_name): * src/font.c (font_parse_family_registry): * src/ftfont.c (ftfont_get_charset): * src/keymap.c (silly_event_symbol_error): * src/menu.c (single_menu_item): * src/sysdep.c (system_process_attributes): Use AUTO_STRING_WITH_LEN if possible. * src/emacs-module.c (module_make_function): * src/fileio.c (report_file_errno, report_file_notify_error): * src/fns.c (Flocale_info): * src/sysdep.c (system_process_attributes): Use AUTO_STRING if possible.

* Omit unnecessary \ before paren in C docstringsPaul Eggert2015-09-161-7/+7
| | | | | | | | | Although \( is needed in docstrings in Elisp code, it is not needed in docstrings in C code, since C function definitiions do not start with a parenthesis. The backslashes made the docstrings a bit harder to read and to format in columns. Also, some C docstrings had ( in column 1 and this did not appear to be causing any problems. So, simplify C docstrings by replacing \( with ( and \) with ).

* Port to 32-bit --with-wide-intPaul Eggert2015-01-101-19/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | Prefer symbol indexes to struct Lisp_Symbol * casted and then widened, as the latter had trouble with GCC on Fedora 21 when configured --with-wide-int and when used in static initializers. * lib-src/make-docfile.c (write_globals): Define and use symbols like iQnil (a small integer, like 0) rather than aQnil (an address constant). * src/alloc.c (garbage_collect_1, which_symbols): * src/lread.c (init_obarray): Prefer builtin_lisp_symbol when it can be used. * src/dispextern.h (struct image_type.type): * src/font.c (font_property_table.key): * src/frame.c (struct frame_parm_table.sym): * src/keyboard.c (scroll_bar_parts, struct event_head): * src/xdisp.c (struct props.name): Use the index of a builtin symbol rather than its address. All uses changed. * src/lisp.h (TAG_SYMPTR, XSYMBOL_INIT): Remove, replacing with ... (TAG_SYMOFFSET, SYMBOL_INDEX): ... new macros that deal with symbol indexes rather than pointers, and which work better on MSB hosts because they shift right before tagging. All uses changed. (DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END): No longer noops on wide-int hosts, since they work now. (builtin_lisp_symbol): New function.
* Compute C decls for DEFSYMs automaticallyPaul Eggert2015-01-051-43/+25

This patch also makes Q constants (e.g., Qnil) constant addresses from the C point of view. * make-docfile.c: Revamp to generate table of symbols, too. Include <stdbool.h>. (xstrdup): New function. (main): Don't process the same file twice. (SYMBOL): New constant in enum global_type. (struct symbol): Turn 'value' member into a union, either v.value for int or v.svalue for string. All uses changed. (add_global): New arg svalue, which overrides value, so that globals can have a string value. (close_emacs_global): New arg num_symbols; all uses changed. Output lispsym decl. (write_globals): Output symbol globals too. Output more ATTRIBUTE_CONST, now that Qnil etc. are C constants. Output defsym_name table. (scan_c_file): Move most of guts into ... (scan_c_stream): ... new function. Scan for DEFSYMs and record symbols found. Don't read past EOF if file doesn't end in newline. * alloc.c, bidi.c, buffer.c, bytecode.c, callint.c, casefiddle: * casetab.c, category.c, ccl.c, charset.c, chartab.c, cmds.c, coding.c: * composite.c, data.c, dbusbind.c, decompress.c, dired.c, dispnew.c: * doc.c, editfns.c, emacs.c, eval.c, fileio.c, fns.c, font.c, fontset.c: * frame.c, fringe.c, ftfont.c, ftxfont.c, gfilenotify.c, gnutls.c: * image.c, inotify.c, insdel.c, keyboard.c, keymap.c, lread.c: * macfont.m, macros.c, minibuf.c, nsfns.m, nsfont.m, nsimage.m: * nsmenu.m, nsselect.m, nsterm.m, print.c, process.c, profiler.c: * search.c, sound.c, syntax.c, term.c, terminal.c, textprop.c, undo.c: * window.c, xdisp.c, xfaces.c, xfns.c, xftfont.c, xmenu.c, xml.c: * xselect.c, xsettings.c, xterm.c: Remove Q vars that represent symbols (e.g., Qnil, Qt, Qemacs). These names are now defined automatically by make-docfile. * alloc.c (init_symbol): New function. (Fmake_symbol): Use it. (c_symbol_p): New function. (valid_lisp_object_p, purecopy): Use it. * alloc.c (marked_pinned_symbols): Use make_lisp_symbol instead of make_lisp_ptr. (garbage_collect_1): Mark lispsym symbols. (CHECK_ALLOCATED_AND_LIVE_SYMBOL): New macro. (mark_object): Use it. (sweep_symbols): Sweep lispsym symbols. (symbol_uses_obj): New function. (which_symbols): Use it. Work for lispsym symbols, too. (init_alloc_once): Initialize Vpurify_flag here; no need to wait, since Qt's address is already known now. (syms_of_alloc): Add lispsym count to symbols_consed. * buffer.c (init_buffer_once): Compare to Qnil, not to make_number (0), when testing whether storage is all bits zero. * dispextern (struct image_type): * font.c (font_property_table): * frame.c (struct frame_parm_table, frame_parms): * keyboard.c (scroll_bar_parts, struct event_head): * xdisp.c (struct props): Use XSYMBOL_INIT (Qfoo) and struct Lisp_Symbol * rather than &Qfoo and Lisp_Object *, since Qfoo is no longer an object whose address can be taken. All uses changed. * eval.c (run_hook): New function. Most uses of Frun_hooks changed to use it, so that they no longer need to take the address of a Lisp sym. (syms_of_eval): Don't use DEFSYM on Vrun_hooks, as it's a variable. * frame.c (syms_of_frame): Add defsyms for the frame_parms table. * keyboard.c (syms_of_keyboard): Don't DEFSYM Qmenu_bar here. DEFSYM Qdeactivate_mark before the corresponding var. * keymap.c (syms_of_keymap): Use DEFSYM for Qmenu_bar and Qmode_line instead of interning their symbols; this avoids duplicates. (LISP_INITIALLY, TAG_PTR) (DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END, XSYMBOL_INIT): New macros. (LISP_INITIALLY_ZERO): Use it. (enum symbol_interned, enum symbol_redirect, struct Lisp_Symbol) (EXFUN, DEFUN_ARGS_MANY, DEFUN_ARGS_UNEVALLED, DEFUN_ARGS_*): Move decls up, to avoid forward uses. Include globals.h earlier, too. (make_lisp_symbol): New function. (XSETSYMBOL): Use it. (DEFSYM): Now just a placeholder for make-docfile. * lread.c (DEFINE_SYMBOLS): Define, for globals.h. (intern_sym): New function, with body taken from old intern_driver. (intern_driver): Use it. Last arg is now Lisp integer, not ptrdiff_t. All uses changed. (define_symbol): New function. (init_obarray): Define the C symbols taken from lispsym. Use plain DEFSYM for Qt and Qnil. * syntax.c (init_syntax_once): No need to worry about Qchar_table_extra_slots.
