* lisp/frame.el (frame--special-parameters): New const.
(frame--complete-parameter-value): New function.
(initial-frame-alist, minibuffer-frame-alist): Use them in
:type. (Bug#39143)
* lisp/cus-start.el (default-frame-alist): Use them here as well.
* src/frame.c (frame_parms): Add comment to try to keep
frame--special-parameters updated.
* configure.ac (ALIGNOF_INT, ALIGNOF_LONG, ALIGNOF_LONG_LONG):
New variables.
(emacs_cv_alignas_unavailable): Define if alignas and structure
alignment primitives are unavailable. In such an environment,
the MSB tagging scheme must be enabled, as must the GNU malloc.
* msdos/sed2v2.inp: Adjust correspondingly.
* src/alloc.c (union emacs_align_type): Remove types which
contain flexible array members. The address of a field
subsequent to an aggregate with flexible array members cannot
validly be taken.
(mark_memory) [!USE_LSB_TAG && !WIDE_EMACS_INT]: Strip type bits
before scanning memory.
* src/emacs.c (main):
* src/eval.c (Fautoload_do_load):
* src/fns.c (Frequire): Rename a number of illogically named
fields.
* src/lisp.h (ALIGNOF_EMACS_INT): Define to the natural
alignment of EMACS_INT.
(IDEAL_GCALIGNMENT): New macro.
(USE_LSB_TAG): Disable if no alignment specifiers are available,
WIDE_EMACS_INT is undefined, and the natural alignment of
EMACS_INT falls short of LSB tagging's requirements.
(gflags): Rename illogically named fields and don't define them
as bitfields, which runs afoul of certain compiler issues.
(will_dump_p, will_bootstrap_p, will_dump_with_pdumper_p)
(dumped_with_pdumper_p): Adjust accordingly.
* src/pdumper.c (VM_SUPPORTED): Define to 0 when !USE_LSB_TAG.
It is better to read dump files into the heap by hand than to be
supplied with an address that is not representable.
(_dump_object_start_pseudovector): Rename to
dump_object_start_pseudovector, to avoid encroaching on reserved
names.
(START_DUMP_PVEC): Adjust correspondingly.
(dump_mmap_contiguous_vm): Preserve errno around failure
cleanup.
(dump_bitset_bit_set_p): Work around certain compiler issues.
(pdumper_load) [!USE_LSB_TAG]: Reject dump file allocations
that are not representable as Lisp_Objects.
Tested on i386-unknown-solaris2.10, sparc-sun-solaris2.10.
* src/term.c (tty_write_glyphs_1): Renamed from tty_write_glyphs. Don't
check if writing the bottom-right corner.
(tty_write_glyphs): New function handling case of writing to the
bottom-right corner, and otherwise calling tty_write_glyphs_1.
* src/pdumper.c (dump_sort_copied_objects, drain_reloc_list)
(dump_do_fixups, dump_do_dump_relocation): Do not expand
Fnreverse multiple times in CALLN. Sun C 5.12 evaluates the
arguments to array initializers to which it expands, which
clobbers the lists being reversed.
lisp/term/w32-win.el contained definitions of variables which
were not used on Cygw32. It is now to split into two files,
common part and Windows native build specific part. The latter
is a new file, lisp/term/w32-nt.el.
* src/image.c (Qlibpng_version, Qlibgif_version)
(Qlibjpeg_version): Don't define on Cygw32 build.
* src/treesit.c (Qtree_sitter__library_abi): Ditto.
* lisp/term/w32-win.el (dynamic-library-alist, libpng-version)
(libgif-version, libjpeg-version, libgnutls-version)
(tree-sitter--library-abi, gui-backend-set-selection)
(gui-backend-get-selection, gui-backend-selection-owner-p)
(gui-selection-exists-p): Moved to lisp/term/w32-nt.el.
* lisp/term/w32-nt.el: New file, separated Windows native build
specific part from lisp/term/w32-win.el.
* lisp/loadup.el: Load term/w32-nt.el on Windows native build.
(Bug#75926)
* src/term.c (Ftty_frame_at):
* src/menu.c (syms_of_menu) <x-popup-menu-function>:
* src/dispnew.c (Fredisplay): Fix "doc:". The extra blank was
preventing 'make-docfile' from recognizing the functions and
variables and extracting their documentation to 'etc/DOC'.
(Bug#76722)
On Cocoa builds of NS Emacs, stipples are now rendered
using masked CGImages instead of patterned NSColors so that
stipples now render with color.
* src/nsimage.m ([EmacsImage stippleMask:]): Use a CGImageMask to
store the stipple mask when building for Cocoa.
* src/nsterm.m (ns_maybe_dumpglyphs_background): Perform a masked
fill to draw stipples when building for Cocoa.
(ns_draw_stretch_glyph_string): Perform a masked fill to draw
stipples when building for Cocoa.
Revert my commit 29a9fd4f4b
and the following commit 1ec0889e7b.
This fixes a bug where ‘emacs -nw’ would sometimes freeze when Emacs is
configured with ‘--with-pgtk --enable-link-time-optimization
--disable-gc-mark-trace’ on GNU/Linux x86-64 (Bug#76729).
As it is not yet clear whether this freeze is due to an Emacs bug that
I introduced, or due to GCC bug 117423
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=117423>,
play it safe for now and revert to the previous state.
* src/androidterm.c (android_show_hourglass): Always define the
hourglass cursor, but...
(android_hide_hourglass): ... restore the invisible cursor
subsequently, if need be.
(android_toggle_visible_pointer): Do not hide the current cursor
if it is an hourglass.
* src/keyboard.c (kbd_buffer_store_selection_event_hold):
* src/keyboard.h (kbd_buffer_store_selection_event_hold): Declare
and define only for (HAVE_X11 || HAVE_PGTK).
Simplify by using separate local vars for struct input_event and
struct selection_input_event, rather than a single local var that
is the union of the two. This makes the code easier to follow by
the human reader, and should help avoid GCC bug 117423
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=117423> and
therefore work around Emacs bug 76559 <https://bugs.gnu.org/76559>.
* src/androidterm.c (handle_one_android_event):
* src/gtkutil.c (xg_widget_key_press_event_cb):
* src/pgtkterm.c (evq_flush):
* src/xterm.c (handle_one_xevent): Use struct input_event and
kbd_buffer_store_event_hold, or struct selection_input_event and
kbd_buffer_store_selection_event_hold, rather than union
buffered_input_event and union buffered_input_event.
* src/keyboard.c (beware_long_paste, maybe_quit_while_no_input):
New functions, broken out from kbd_buffer_store_buffered_event.
(kbd_buffer_store_event_hold): Define here, with a simplified
version of the body of the old kbd_buffer_store_buffered_event,
rather than defining in keyboard.h. Specialize to struct
input_event.
(kbd_buffer_store_selection_event_hold): New function; it is
a simplified version of the old kbd_buffer_store_buffered_event,
specialized to struct selection_input_event.
(is_ignored_event_kind): Accept enum event_kind instead of
union buffered_input_event. All callers changed.
* src/keyboard.h (kbd_buffer_store_event_hold):
Remove definition, as keyboard.c now defines it.
* src/pgtkterm.c (evq_grow_if_needed): New function.
(evq_enqueue, evq_selection_enqueue): Two functions now,
not one. Args are now struct input_event const * or
struct selection_input_event const *, not
union buffered_input_event *. All callers changed.
This lets us simplify the callers so that they need
not use the union.
1. Prefer "native-compiled" to "native compiled".
The adjective "native-compiled" with the hyphen is generally more
consistent with the typical pattern in English, especially when the
compound modifies a noun (e.g., "native-compiled code").
2. Prefer "natively compiled" to "natively-compiled".
The adverb "natively" modifies "compiled", and it is standard not
to hyphenate an adverb + adjective combination when the adverb ends
in -ly (e.g., "code that is natively compiled").
For example, note that we say "high-speed internet" but "highly
performant code".

In the mid-1990s, these functions were moved from Lisp to C to
"improve performance". However, Moore's Law, and perhaps other
improvements too, has made this rationale irrelevant.
On this machine, with --native-compilation=no, I observed only a
slight ~4% performance difference. For example, displaying a buffer
full of widgets (e.g., 'M-x customize RET browse-url RET') takes 4ms
here, meaning the performance gap is under 0.1ms. Even on less
powerful machines, this difference would remain imperceptible. Given
this, let's lift these functions back to to Lisp, which offers the
usual benefits.
We already have solid test coverage, but let's add a more focused test
for 'widget-get' and 'widget-put' to be thorough.
* lisp/wid-edit.el (widget-put, widget-get, widget-apply): Move to
Lisp from...
* src/fns.c (Fwidget_put, Fwidget_get, Fwidget_apply): ...here.
(syms_of_fns): Remove defsubrs for the above functions.
* test/lisp/wid-edit-tests.el
(widget-test-editable-field-widget-get/put): New test.
* src/android.c (android_run_select_thread, android_init_events)
(android_select): Enable self-pipes on all Android versions <= 21.
The Android C library provides a functioning pselect on these
systems, but it does not apply the signal mask atomically.
(android_run_select_thread): Correct typo. This never produced
any adverse consequences, as the relevant signals would already
have been blocked by `setupSystemThread'.
Do not merge to master.
* src/android.c (android_init_thread_events)
(android_run_select_thread): Guarantee that the select thread is
initialized before returning.
* test/src/process-tests.el
(process-tests/fd-setsize-no-crash/make-process)
(process-tests/fd-setsize-no-crash/make-pipe-process)
(process-tests/fd-setsize-no-crash/make-network-process)
(process-tests/fd-setsize-no-crash/make-serial-process): Skip on
Android.
* src/android.c (struct android_thread_event_queue): New
structure. Move global pselect arguments, mutexes, and
semaphores, and pipes here.
(struct android_event_queue) <select_mutex, select_thread>:
Remove to the above-named struct.
(android_init_thread_events, android_finalize_thread_events)
(android_get_poll_thread): New functions.
(android_run_select_thread): Accept a set of mutexes and
thread-local data as the first argument, and operate with them
rather than globals.
(android_handle_sigusr1): Rename to
`android_handle_poll_signal'. Set thread-specific cancellation
indicator.
(android_init_events): Properly abort after a fatal condition.
Enable interruptible polling on Android 5.1 and later, not 4.2.
(android_select): Never check for queries here, but in
thread_select, if threads are enabled. Adapt to per-thread
polling threads and only enable interruptible polling on Android
5.1 and later.
(android_before_select): New function.
* src/android.h (android_before_select): New declaration.
* src/thread.c (thread_select): Call `android_before_select'
before the global lock is released.
* src/keymap.c (Fcurrent_active_maps): For clicks on mode-line and
header-line, always override the keymaps at buffer position.
