src/.gdbinit (xsymname): New subroutine. (xprintsym, initial-tbreak): Use it to access the name of a symbol in a way that doesn't cause GDB to barf when it tries to dereference a NULL pointer.

src/xdisp.c (next_element_from_c_string): Use Lisp integer zero as the object. (set_cursor_from_row, try_cursor_movement, dump_glyph) (insert_left_trunc_glyphs, append_space_for_newline) (extend_face_to_end_of_line, highlight_trailing_whitespace) (find_row_edges, ROW_GLYPH_NEWLINE_P, Fmove_point_visually) (Fbidi_resolved_levels, produce_special_glyphs) (rows_from_pos_range, mouse_face_from_buffer_pos) (note_mouse_highlight): Use nil as the object for glyphs inserted by the display engine, and test with NILP instead of INTEGERP. src/w32fns.c (Fx_show_tip): Use NILP to test for glyphs inserted by the display engine. src/xfns.c (Fx_show_tip): Use NILP to test for glyphs inserted by the display engine. src/dispextern.h (struct glyph, struct it): Update comments for the OBJECT members.

* lisp.h (DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END): Define to empty on platforms where EMACS_INT_MAX != INTPTR_MAX, as GCC (at least) does not allow a constant initializer to widen an address constant.

This is a followup to the "Port Qnil==0 XUNTAG to clang" patch. Although clang doesn't need it, some other compiler might, and it's easy enough to be safe.
-
Paul Eggert authored
Apparently clang removed support for the alloc_size attribute.

clang has undefined behavior if the program subtracts an integer from (char *) 0. Problem reported by YAMAMOTO Mitsuharu in: http://lists.gnu.org/archive/html/emacs-devel/2015-01/msg00132.html * lisp.h (lisp_h_XUNTAG) [USE_LSB_TAG]: (XUNTAG) [!USE_LSB_TAG]: Port to clang 3.5.0.

Fixes Bug#15880. If USE_LSB_TAG, arrange for the representation of Qnil to be zero so that NILP (x) is equivalent to testing whether x is 0 at the machine level. The overall effects of this and the previous patch shrink the size of the text segment by 2.3% and speeds up compilation of all the .elc files by about 0.5% on my platform, which is Fedora 20 x86-64. * lib-src/make-docfile.c (compare_globals): * src/lisp.h (lisp_h_XPNTR, lisp_h_XSYMBOL, lisp_h_XUNTAG) (make_lisp_symbol) [USE_LSB_TAG]: Symbols now tag the difference from lispsym, not the pointer. (lisp_h_XUNTAGBASE, TAG_SYMPTR): New macros. (Lisp_Int0, Lisp_Int1, Lisp_Symbol, Lisp_Misc, Lisp_String, Lisp_Cons): Renumber so that Lisp_Symbol is 0, so that Qnil is zero. (XSYMBOL): New forward decl. (XUNTAGBASE): New function. (XUNTAG): Use it.

Fixes Bug#15880. 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.

Without this patch, "temacs -nw" fails with the diagnostic "emacs: Symbol's function definition is void: frame-windows-min-size" and messes up the tty's state. * lib-src/make-docfile.c (write_globals): Declare Fframe_windows_min_size with ATTRIBUTE_CONST, too. Sort. * src/frame.c (Fframe_windows_min_size): New placeholder function. (syms_of_frame): Define it. * src/window.c (Fwindow__sanitize_window_sizes): New placeholder. (syms_of_window): Define it.

($(THEFILE)c, .el.elc, $(MH_E_DIR)/mh-loaddefs.el) ($(TRAMP_DIR)/tramp-loaddefs.el, $(CAL_DIR)/cal-loaddefs.el) ($(CAL_DIR)/diary-loaddefs.el, $(CAL_DIR)/hol-loaddefs.el): Use AM_V_GEN to lessen 'make' chatter.
