* lisp.h (USE_2_TAGS_FOR_INTS): Remove, as it was always defined.
(LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
(LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):
Simplify under the assumption that USE_2_TAGS_FOR_INTS is defined.
(INTTYPEBITS): New macro, for clarity.
(INTMASK, MOST_POSITIVE_FIXNUM): Use it.
(LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P): Simplify
now that USE_LSB_TAG is always defined.
(TYPEMASK, XINT) [USE_LSB_TAG]: Remove unnecessary cast.
(make_number) [!USE_LSB_TAG]: Use INTMASK; that's simpler.
* src/s/usg5-4-common.h, src/s/unixware.h:
Remove define/undef of HAVE_SYSV_SIGPAUSE (not used since 2010-05-04).
* admin/CPP-DEFINES: Remove HAVE_SYSV_SIGPAUSE.
* 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.
* configure.in: Check for MagickMergeImageLayers.
* src/image.c (imagemagick_load_image): Use MagickFlattenImage if
MagickMergeImageLayers is undefined. Use pixel pusher loop if
MagickExportImagePixels is undefined.
Fixes: debbugs:11678
* src/alloc.c (make_byte_code): New function.
(Fmake_byte_code): Use it. Don't purify here.
* src/lread.c (read1): Use it as well to avoid extra allocation.
dbus_type_is_basic if available.
(xd_extract_signed, xd_extract_unsigned): Rename from
extract_signed and extract_unsigned, respectively. Adapt callers.
src/dispnew.c (showing_window_margins_p): Undo last change, which
was done due to an inadvertent commit.
(adjust_frame_glyphs_for_frame_redisplay): Do call
showing_window_margins_p.
* lisp/startup.el (argv, argi): Make lexically scoped.
* lisp/emacs-lisp/float-sup.el (pi): Use internal-make-var-non-special.
* lisp/emacs-lisp/cl-macs.el: Use lexical-binding.
Rename cl-bind-* to cl--bind-*.
* lisp/files.el: Don't require `cl' since it doesn't use it.
* lisp/emacs-lisp/pcase.el, lisp/emacs-lisp/macroexp.el: Add coding cookie.
* src/eval.c (Fmake_var_non_special): New primitive.
(syms_of_eval): Defsubr it.
* src/lread.c (syms_of_lread): Mark `values' as lexically scoped.
* src/lisp.h (struct vectorlike_header): New field `nbytes',
adjust comment accordingly.
* src/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.
(COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
(VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
(VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
(VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
(VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.
(roundup_size): New constant.
(struct vector_block): New data type.
(vector_blocks, vector_free_lists, zero_vector): New variables.
(all_vectors): Renamed to `large_vectors'.
(allocate_vector_from_block, init_vectors, allocate_vector_from_block)
(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.
* doc/lispref/internals.text (Garbage Collection): Document new
vector management code and vectorlike_header structure.
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.
* configure.in (PAXCTL): Check for paxctl.
* src/Makefile.in (PAXCTL): Define.
(temacs$(EXEEXT)): Disable memory randomization for the temacs
binary via PaX flags if the paxctl utility is available.
(emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
Restore PaX flags to their default.
Fixes: debbugs:11398

(mode-line-read-only-help-echo, mode-line-modified-help-echo):
New functions.
(mode-line-mule-info, mode-line-modified): Use them.
(mode-line-eol-desc, propertized-buffer-identification):
Consistency fixes for help text.
Fixes: debbugs:11226
* lisp/bindings.el: Remove explicit help-echo from format-mode-line.
(mode-line-front-space, mode-line-end-spaces)
(mode-line-misc-info): New variables.
(mode-line-modes, mode-line-position): Move the default value to
the variable definition.
(mode-line-default-help-echo): New defcustom.
* src/buffer.c (buffer_local_value_1): New function, split from
Fbuffer_local_value; can return Qunbound.
(Fbuffer_local_value): Use it.
(Vmode_line_format): Docstring tweaks.
* src/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.
* doc/lispref/modes.texi (Mode Line Data): Use "mode line construct"
terminology for consistency.
* src/keyboard.c: Export real-this-command to Elisp.
(syms_of_keyboard): Rename real_this_command to Vreal_this_command
and DEFVAR it. Update all users.
Fixes: debbugs:11506
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.
* lisp/image.el: For clarity, call imagemagick-register-types at
top-level, rather than relying on a custom :initialize.
(imagemagick-types-enable): New option.
(imagemagick-register-types): Respect imagemagick-types-inhibit.
If disabling support, remove elements altogether rather
than using an impossible regexp.
(imagemagick-types-inhibit): Give it the default init function.
* src/image.c (Fimagemagick_types): Doc fix.
* etc/NEWS: Mention this.
Fixes: debbugs:11557
* xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
[HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
Use 'float' consistently, rather than 'float' in most places
and 'double' in a couple of places.
