(Bug#40561)
* src/xfns.c (Fx_gtk_debug, Sx_gtk_debug): Define only for GTK
versions >= 3.14.0 so gtk_window_set_interactive_debugging is
defined. Reported by Andreas Schwab <schwab@linux-m68k.org>.
I added this macro in 2011 to fix some signedness comparison bugs.
However, it’s a weird macro and the bugs can be fixed in a
more-straightforward way. This helps performance slightly (0.5%) on my
platform (Fedora 31 x86-64, GCC 9.3.1 with -O2).
* src/casefiddle.c (do_casify_natnum): Use simple comparison
instead of UNSIGNED_CMP.
* src/character.h (CHAR_VALID_P, SINGLE_BYTE_CHAR_P, CHAR_STRING):
* src/composite.h (COMPOSITION_ENCODE_RULE_VALID):
* src/lisp.h (ASCII_CHAR_P):
Now an inline function, and uses simple comparison instead of
UNSIGNED_CMP.

(IMAGE_FROM_ID, IMAGE_OPT_FROM_ID): Move these to ...
* src/frame.h (FACE_FROM_ID, FACE_FROM_ID_OR_NULL)
(IMAGE_FROM_ID, IMAGE_OPT_FROM_ID): ... here, and make them
inline functions that no longer use UNSIGNED_CMP.
* src/keyboard.c (read_char): UNSIGNED_CMP is not needed here
since XFIXNAT always returns a nonnegative value.
* src/lisp.h (UNSIGNED_CMP): Remove; no longer used.
* lisp/hi-lock.el (hi-lock-interactive-lighters): New buffer-local variable.
(hi-lock-mode): Set hi-lock-interactive-lighters to nil.
(hi-lock-line-face-buffer): Use case-fold-search and search-upper-case.
(hi-lock-face-buffer): Add new arg LIGHTER. Use case-fold-search,
search-upper-case and search-spaces-regexp.
(hi-lock-face-phrase-buffer): Don't call hi-lock-process-phrase.
Use case-fold-search, search-upper-case and search-whitespace-regexp.
(hi-lock-face-symbol-at-point): Use case-fold-search and search-upper-case.
(hi-lock-unface-buffer): Use hi-lock-interactive-lighters to get
a human-readable string for completion and x-popup-menu.
(hi-lock-process-phrase): Remove function.
(hi-lock-set-pattern): Add new args LIGHTER, CASE-FOLD, SPACES-REGEXP.
Set font-lock pattern to a search function. Add mapping from
lighter or regexp to pattern to hi-lock-interactive-lighters.
Let-bind case-fold-search and search-spaces-regexp in search functions.
* lisp/isearch.el (isearch--highlight-regexp-or-lines): Replace ugly code

(cl-font-lock-built-in-mode): New minor mode.
They already did return their argument under some circumstances;
this change broadens it to further reduce allocation in common cases
(bug#40407).
* src/coding.c (convert_string_nocopy): New function.

Don't make it sound like `:key-sequence nil` is any different than the
absence of `:key-sequence`. And the performance advantage of
`:key-sequence` disappeared long ago.
* src/dispnew.c (update_window): Reset the window's
'must_be_updated_p' flag if the window's update was completed
without interruption. This fixes redisplay glitches when
'redisplay-dont-pause' is nil, at least on MS-Windows, because
'expose_window' doesn't redraw the exposed rectangle when the
window's 'must_be_updated_p' flag is set.
* lisp/cedet/pulse.el (pulse-reset-face): Propagate the :extend
attribute of FACE to the face used for displaying the pulse.
Reported by Adam Porter <adam@alphapapa.net>.
Spotted by Kazuhiro Ito.
* src/coding.c (code_convert_string):
Set Vlast_coding_system if appropriate.
* test/src/coding-tests.el (coding-nocopy-ascii): Add test.
To sidestep conversion altogether when EOL conversion applies, we must
either be encoding a string without NL, or decoding without CR.
* src/coding.c (string_ascii_p): Revert to a pure predicate.
(code_convert_string): Fix logic. Don't use uninitialised
ascii_p (removed). Use memchr to detect CR or LF in string when needed.
* test/src/coding-tests.el (coding-nocopy-ascii):
Update tests to include encodings with explicit EOL conversions.
* src/coding.c (Fcheck_coding_systems_region): Don't crash if
the third arg contains something that isn't a coding system.
* test/src/coding-tests.el (coding-check-coding-systems-region):
New test.
Callers of ENCODE_FILE and DECODE_FILE should not assume that these
functions always return a new string (bug#40407).
* src/w32fns.c (Fw32_shell_execute):
* src/w32proc.c (Fw32_application_type):
Sink taking the address of a Lisp string past GC points.
Copy values returned from ENCODE_FILE before mutating them.
* src/coding.c (string_ascii_p): Return a negative value if an
all-ASCII string STR includes the CR character, otherwise a
positive value.
(code_convert_string): If the string is ASCII, but includes CR
characters, use the fast path only if EOL doesn't need to be
decoded. (Bug#40519)
* test/src/coding-tests.el (coding-nocopy-ascii): Add more tests
for bug#40519.
* src/coding.c (string_ascii_p): Return a negative value if an
all-ASCII string STR includes the CR character, otherwise a
positive value.
(code_convert_string): If the string is ASCII, but includes CR
characters, use the fast path only if EOL doesn't need to be
decoded. (Bug#40519)
* test/src/coding-tests.el (coding-nocopy-ascii): Add tests for
bug#40519.
* lisp/jit-lock.el (jit-lock-contextually): Clarify the jit-lock
operation when 'jit-lock-contextually' is non-nil and non-t.
* doc/lispref/modes.texi (Syntactic Font Lock)
(Other Font Lock Variables): Document the relation between
'jit-lock-register', 'font-lock-keywords-only', and syntactic
refontification.
* src/gtkutil.c (xg_frame_set_char_size): Skip resizing if the
target dimensions are unchanged for child frames with
'resize-mode' resize policy as well.
Now that -Og inlining has been improved this is no longer helpful.
* src/Makefile.in (KEY_OPS_CFLAGS): Remove. All uses removed.
This improved CPU performance of ‘make compile-always’ by 5% on my
platform, which was gcc -Og, GCC 9.3.1 20200317 (Red Hat 9.3.1-1),
Fedora 31 x86-64 (AMD Phenom II X4 910e, circa 2010).
* src/conf_post.h (EXTERN_INLINE) [!EMACS_EXTERN_INLINE]:
Make it static inline, not merely static. This is a worthwhile
performance improvement on my two platforms A and B (see below).
On my platform A this change improves user+system CPU performance of
‘make compile-always’ by 52% on an -Og build, and by 1.4% on the
default -O2 build. On my platform B this improves the same benchmark
by 41% on an -Og build, and by -0.8% on the default -O2 build.
That "-0.8%" is a small negative for this change, and I recall that
it is why I didn't make this change earlier. However, Platform B uses
an older GCC so we needn't worry overmuch about this small negative.
With this change the performance advantage of -O2 over -Og has dropped
on platform A; formerly -O2 was 87% faster than -Og, and now it is
only 25% faster. On platform B the performance advantage of -O2 over
-Og has dropped from being 62% faster to being 14% faster.
Platform A is GCC 9.3.1 20200317 (Red Hat 9.3.1-1) on Fedora 31
x86-64 (AMD Phenom II X4 910e, circa 2010). Platform B is GCC (Ubuntu
7.5.0-3ubuntu1~18.04) 7.5.0 on Ubuntu 18.04.4 (Intel Xeon E3-1225 V2,
circa 2012).

Unify the behavior of source buffer display for gdb-mi. Before this
change, stepping and other gdb command handlers use 'gud-display-line',
and 'gdb-goto-breakpoint' uses 'gdb-display-source-buffer'. Now whenever
gdb-mi code tries to open a source buffer, 'gdb-display-source-buffer'
is used. Also, simplify the logic in 'gdb-display-source-buffer' and
add a feature to limit the maximum number of source windows.
* doc/emacs/building.texi (GDB User Interface Layout): Explain source
file display in GDB.
* etc/NEWS (gdb-mi): Add news about source display.
* lisp/progmodes/gdb-mi.el (gdb-source-window): Remove variable,
change to 'gdb-source-window-list'.
(gdb-source-window-list): New variable.
(gdb-display-source-buffer-action,
gdb-max-source-window-count): New options.
(gdb-init-1, gdb-setup-windows, gdb-load-window-configuration,
gdb-restore-windows): Use 'gdb-source-window' rather than
'gdb-source-window-list'.
(gdb-save-window-configuration): Use 'gdb-source-window' rather than
'gdb-source-window-list'. And consider any buffer that is not a
command or function buffer as a source buffer.
(gdb-display-source-buffer): Use new logic.
(gdb-goto-breakpoint): Remove 'display-buffer' call
and don't set 'gdb-source-buffer' anymore.
* lisp/progmodes/gud.el (gud-display-line): If used by gdb-mi, use
'gdb-display-source-buffer' rather than 'display-buffer'. Don't set
'gdb-source-buffer' anymore.
Re-implement 'mouse-drag-frame' via two new functions -
'mouse-drag-frame-resize' and 'mouse-drag-frame-move'. This is
needed because with some toolkits the notifications for frame
movement and resizing arrive asynchronously, breaking any
calculations using intermediate frame sizes and positions.
* lisp/mouse.el (mouse-drag-mode-line, mouse-drag-left-edge)
(mouse-drag-top-left-corner, mouse-drag-top-edge)
(mouse-drag-top-right-corner, mouse-drag-right-edge)
(mouse-drag-bottom-right-corner, mouse-drag-bottom-edge)
(mouse-drag-bottom-left-corner): Call 'mouse-drag-frame-resize'
instead of 'mouse-drag-frame'.
(mouse-drag-frame): Split into two new functions -
'mouse-drag-frame-move' and 'mouse-drag-frame-resize'.
(mouse-drag-frame-resize, mouse-drag-frame-move): New functions
to implement functionality of the removed 'mouse-drag-frame'.
(1) Provide new option 'x-gtk-resize-child-frames' which allows
to either hide a child frame during resizing or asks GTK to
resize it "immediately". This is needed because desktops like
GNOME shell otherwise won't allow resizing child frames at all.
(2) Do not try to synchronize the position of a child frame
after moving it. Needed because the present implementation
introduces a 0.5 secs delay which makes dragging child frames
virtually impossible with Lucid and Motif toolkits on desktops
like GNOME shell that use invisible outer frame borders.
For further information see the thread starting with
https://lists.gnu.org/archive/html/emacs-devel/2020-01/msg00343.html
* src/frame.c (syms_of_frame): New symbol Qxg_frame_set_char_size_4.
* src/gtkutil.c (xg_frame_set_char_size): Hide child frame

* src/xfns.c (x_set_parent_frame, Fx_create_frame): Set
gtk_container_resize_mode to GTK_RESIZE_IMMEDIATE for child
frames when'x-gtk-resize-child-frames' equals 'resize-mode'.
(Fx_gtk_debug): New function to toggle interactive GTK debugging
from within Emacs.
(syms_of_xfns): New symbols Qhide and Qresize_mode.
(x-gtk-resize-child-frames): New option that allows to resize
child frames on desktops like GNOME shell (with the mutter WM)
that otherwise refuse to resize them.
* src/xterm.c (x_set_offset): Don't x_sync_with_move for child
frames, it makes moving child frames virtually impossible with
the Lucid and Motif toolkits.
