+
+        * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
+        instead of union.
+        (XLI, XIL): Define.
+        (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG): Use
+        them.
+        * emacs.c (gdb_use_struct): Renamed from gdb_use_union.
+        * .gdbinit: Check gdb_use_struct instead of gdb_use_union.
+        * alloc.c (widen_to_Lisp_Object): Removed.
+        (mark_memory): Use XIL instead of widen_to_Lisp_Object.
+        * frame.c (delete_frame): Remove outdated comment.
+        * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
+        USE_LISP_UNION_TYPE.
+        (Fw32_unregister_hot_key): Likewise.
+        (Fw32_toggle_lock_key): Likewise.
+        * w32menu.c (add_menu_item): Likewise.
+        (w32_menu_display_help): Use XIL instead of checking
+        USE_LISP_UNION_TYPE.
+        * w32heap.c (allocate_heap): Don't check USE_LISP_UNION_TYPE.
+        (init_heap): Likewise.
+        * w32term.c (w32_read_socket): Update comment.
+
+2012-06-13  Glenn Morris  <rgm@gnu.org>
+
+        * s/usg5-4-common.h, src/s/unixware.h:
+        Remove define/undef of HAVE_SYSV_SIGPAUSE (not used since 2010-05-04).
+
+        * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
+
+2012-06-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+        USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
+        * alloc.c (make_number) [!defined make_number]:
+        Remove, as lisp.h always defines this now.
+        (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
+        (roundup_size): Verify that it is a power of 2.
+        * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
+        * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
+        * lisp.h (USE_LSB_TAG): Allow the builder to compile with
+        -DUSE_LSB_TAG=0, to override the automatically-selected default.
+        USE_LSB_TAG now is always defined to be either 0 or 1.
+        All uses changed.
+        (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
+        code works fine either way, and efficiency is not a concern here,
+        as the union type is for debugging, not for production.
+        (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
+        Use an inline function on all platforms when using the union type,
+        since this is simpler and 'static inline' can be used portably
+        within Emacs now.
+        (LISP_INITIALLY_ZERO): New macro.
+        (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
+        (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

+        Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
+        would generate the diagnostic "Making \302\247 buffer-local while
+        let-bound!".
+
+2012-06-08  Eli Zaretskii  <eliz@gnu.org>
+
+        * dispnew.c (showing_window_margins_p): Undo last change, which

+
+2012-06-08  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        Block-based vector allocation of small vectors.
+        * lisp.h (struct vectorlike_header): New field `nbytes',
+        adjust comment accordingly.
+        * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
+        to denote vector blocks. Adjust users (live_vector_p,
+        mark_maybe_pointer, valid_lisp_object_p) accordingly.

+        (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),

+        (sweep_vectors): New functions.
+        (allocate_vectorlike): Return `zero_vector' as the only vector of
+        0 items. Allocate new vector from block if vector size is less than
+        or equal to VBLOCK_BYTES_MAX.
+        (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
+        (init_alloc_once): Add call to init_vectors.

+
+2012-06-07  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * doprnt.c (doprnt): Truncate multibyte char correctly.
+        Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
+        would mishandle a string argument "Xc" if X was a multibyte
+        character of length 2: it would truncate after X's first byte
+        rather than including all of X.
+
+2012-06-06  Chong Yidong  <cyd@gnu.org>
+
+        * buffer.c (word_wrap): Doc fix.

+
+        * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
+        buffer (Bug#11226).
+
+2012-06-03  Chong Yidong  <cyd@gnu.org>
+
+        * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
+        (note_mode_line_or_margin_highlight): If there is no help echo,
+        use mode-line-default-help-echo.  Handle the case where the mouse
+        position is past the end of the mode line string.
+
+        * buffer.c (buffer_local_value_1): New function, split from
+        Fbuffer_local_value; can return Qunbound.
+        (Fbuffer_local_value): Use it.

+        (syms_of_keyboard): Rename real_this_command to Vreal_this_command
+        and DEFVAR it.  Update all users.
+
+2012-06-02  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * minibuf.c (Fassoc_string): Remove duplicate declaration.
+
+        * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
+        Convert pctcpu and pctmem to Lisp float properly.
+        Let the compiler fold better, as 100.0/0x8000 is exact.
+
+2012-06-02  Andreas Schwab  <schwab@linux-m68k.org>
+
+        * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

+
+2012-06-01  Paul Eggert  <eggert@cs.ucla.edu>

+
+2012-06-01  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        For a 'struct window', replace some Lisp_Object fields to
+        bitfields where appropriate, remove unused fields.
+        * window.h (struct window): Remove unused 'last_mark_x' and
+        'last_mark_y' fields.  Rename 'mini_p' field to 'mini',
+        change it's type from Lisp_Object to bitfield.
+        Change type of 'force_start', 'optional_new_start',
+        'last_had_star', 'update_mode_line' and 'start_at_line_beg'
+        fields from Lisp_Object to bitfield. Adjust users accordingly.
+
 2012-05-31  Paul Eggert  <eggert@cs.ucla.edu>
 
         Pacify gcc -Wdouble-precision when using Xaw.
