* etc/NEWS: Mention that 'mail-from-style' is obsolete.
(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.
* src/dispextern.h (FACE_FROM_ID, FACE_FROM_ID_OR_NULL)
(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
with let-binding of case-fold-search, search-upper-case, search-spaces-regexp.

Use lambda.
* doc/emacs/display.texi (Scrolling): Add a paragraph on using jit-lock
deferred fontification as a way of obviating Emacs hanging after
auto-repeated scrolling.
Change copyright to FSF and licence to GPLv3+.
Tweak Commentary (the code doesn't seem to provide the lambda
prettification mentioned).
(cl-font-lock-add-regexes): Remove macro.
(cl-font-lock-built-in-keywords): New variable.
(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'.
