+2015-01-11  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Port to MSB hosts without optimization
+        E.g., when configuring --with-wide-int CFLAGS='-O0' on x86,
+        the inline function XTYPE needs to be declared before being used.
+        * lisp.h (XTYPE): New forward declaration.
+
+2015-01-10  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Port to 32-bit --with-wide-int
+        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.
+        * alloc.c (garbage_collect_1, which_symbols):
+        * lread.c (init_obarray):
+        Prefer builtin_lisp_symbol when it can be used.
+        * dispextern.h (struct image_type.type):
+        * font.c (font_property_table.key):
+        * frame.c (struct frame_parm_table.sym):
+        * keyboard.c (scroll_bar_parts, struct event_head):
+        * xdisp.c (struct props.name):
+        Use the index of a builtin symbol rather than its address.
+        All uses changed.
+        * 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.
+
+        Port to HAVE_FREETYPE && !HAVE_XFT
+        * dispextern.h (struct face.extra) [HAVE_FREETYPE && !HAVE_XFT]:
+        * font.h (syms_of_xftfont) [HAVE_FREETYPE && !HAVE_XFT]:
+        Declare in this case too.
+
+2015-01-10  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32fns.c (Fw32_register_hot_key): Use XINT instead of XLI.
+
+        * w32notify.c (Fw32notify_add_watch, w32_get_watch_object): Use
+        make_pointer_integer instead of XIL.
+        (Fw32notify_rm_watch): Use XINTPTR instead of XLI.
+
+        * w32inevt.c (handle_file_notifications): Use make_pointer_integer
+        instead of XIL.  Put a list of the descriptor, action, and file
+        name in event->arg, instead of spreading them between event->code
+        and event->arg.

+        and event->arg.
+
+        * keyboard.c (kbd_buffer_get_event) [HAVE_W32NOTIFY]: Adjust Lisp
+        event creation to changes in w32term.c and w32inevt.c above.
+
+2015-01-09  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Port Qnil==0 changes to 32-bit --with-wide-int
+        * lisp.h (lisp_h_XSYMBOL, XSYMBOL): Assume USE_LSB_TAG in the
+        macro-implemented version.  For the non-USE_LSB_TAG case, supply
+        a new inline function that is the inverse of the new TAG_SYMPTR.
+        (lisp_h_XUNTAGBASE, XUNTAGBASE): Remove.  All uses removed.
+        (TAG_SYMPTR) [!USE_LSB_TAG]: If the pointer subtraction yields a
+        negative number, don't allow sign bits to bleed into the encoded
+        value.  Shift in zero bits instead.
+
+        Refactor pointer-to-integer conversion
+        * gfilenotify.c (monitor_to_lisp, lisp_to_monitor):
+        Rename and move to lisp.h.  All uses changed.
+        * lisp.h (XINTPTR, make_pointer_integer): New inline functions,
+        which are renamed from gfilenotify.c's lisp_to_monitor and
+        monitor_to_lisp, and with more-generic void * signatures.
+
+2015-01-08  Eli Zaretskii  <eliz@gnu.org>
+
+        * dispnew.c (buffer_posn_from_coords): Fix the value of the column
+        returned for right-to-left screen lines.  (Before the change on
+        2014-12-30, the incorrectly-computed X pixel coordinate concealed
+        this bug.)
+
+        * .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.
+
+        * 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)

+        (note_mouse_highlight): Use nil as the object for glyphs inserted
+        by the display engine, and test with NILP instead of INTEGERP.
+        (Bug#19535)
+
+        * w32fns.c (Fx_show_tip): Use NILP to test for glyphs inserted by
+        the display engine.
+
+        * xfns.c (Fx_show_tip): Use NILP to test for glyphs inserted by
+        the display engine.
+
+        * dispextern.h (struct glyph, struct it): Update comments for the
+        OBJECT members.
+
+2015-01-08  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Port new Lisp symbol init to x86 --with-wide-int
+        * 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.
+
+        * lisp.h (TAG_SYMPTR): Don't do arithmetic on NULL.
+        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.
+
+        * conf_post.h (ATTRIBUTE_ALLOC_SIZE): Port to clang 3.5.0.
+        Apparently clang removed support for the alloc_size attribute.
+
+        Port Qnil==0 XUNTAG to clang
+        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.
+
+        Port GFileMonitor * hack to Qnil==0 platforms
+        Reported by Glenn Morris in: http://bugs.gnu.org/15880#112
+        * gfilenotify.c (monitor_to_lisp, lisp_to_monitor): New functions.
+        (dir_monitor_callback, Fgfile_add_watch, Fgfile_rm_watch): Use them.
+
+2015-01-06  Jan Djärv  <jan.h.d@swipnet.se>
+
+        * nsterm.m (x_set_window_size): Call updateFrameSize to get real
+        size instead of using widht/height.  The frame may be constrained.
+
+2015-01-05  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * lisp.h (XSYMBOL): Parenthesize id in forward decl.
+        Needed when neither optimizing nor inlining.
+        Also, sort decls alphabetically.
+
+2015-01-05  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32proc.c, w32.h, w32fns.c, w32font.c, w32menu.c, w32notify.c:
+        * w32proc.c, w32select.c, w32term.c, w32uniscribe.c: Remove
+        declarations of Q* variables that represent symbols.
+
+2015-01-05  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Use 0 for Qnil
+        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.
+        * 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.
+
+        Compute C decls for DEFSYMs automatically
+        Fixes Bug#15880.
+        This patch also makes Q constants (e.g., Qnil) constant addresses
+        from the C point of view.
+        * alloc.c, bidi.c, buffer.c, bytecode.c, callint.c, casefiddle.c:
+        * casetab.c, category.c, ccl.c, charset.c, chartab.c, cmds.c, coding.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:

+        * 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.h (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.
