Make some C symbols static if they don’t need to be extern.
Also, remove a couple of functions that were discovered to be
unused as a result of this process, and mark two extern
functions intended to be usable from GDB.

Port to planned glibc 2.43 (scheduled for February 2026),
which will support qualifier-generic standard functions; see:
https://sourceware.org/git/?p=glibc.git;a=commit;h=cd748a63ab1a7ae846175c532a3daab341c62690
For example, strchr (P, C) will return pointer to const if P is
pointer to const. The idea is to catch dumb programming errors when a
program mistakenly uses strchr to convert a pointer to const
to an unrestricted pointer. This feature is required by C23,
and will be enabled by default in GCC 15.
* src/callint.c (Fcall_interactively):
Respect constness of pointer when calling memchr.
* src/gtkutil.c (xg_get_font):
2nd arg is char *, not const char *.
* src/xfaces.c (parse_float_color_comp): Return bool, not double.
New arg DST. All callers changed. This makes it easier for
callers to use char const *.
(parse_color_spec): Respect constness of pointer when calling strchr.
Problem for mpz_get_d_rounded reported by Helmut Eller in:
https://lists.gnu.org/r/emacs-devel/2025-11/msg00795.html
* lib-src/make-docfile.c (DEFUN_pure): New constant.
(write_globals, scan_c_stream): Support "attributes: pure".
* src/bignum.h (mpz_get_d_rounded):
* src/data.c (Fsymbolp, Fmodule_function_p, Fintegerp, Fnumberp):
* src/lisp.h (bignum_to_double, bignum_to_intmax)
(bignum_to_uintmax, bignum_bufsize):
Now pure, not const, since they depend on current state.
For example, Fsymbolp now inspects symbols_with_pos_enabled,
and the bignum functions inspect bignum contents in memory.
* src/data.c (Feq):
* src/xfaces.c (Fface_attribute_relative_p):
No longer const, since they might abort when debugging.
* src/pdumper.h (pdumper_object_p, pdumper_cold_object_p)
(pdumper_find_object_type, pdumper_object_p_precise):
These are not const functions. But there is no need to declare
them to be pure, either, as they’re inline so the compiler can
figure it out.
* src/xfaces.c (get_lface_attributes): Avoid crashes if F is NULL.
This happens when 'face_inheritance_cycle' is for some reason
called for the default attributes of a face (which are applicable
to future frames). We avoid the crashes by not consulting face
remapping in that case, since face remapping is buffer-local, and
therefore cannot possibly affect face defaults. (Bug#79790)
* src/xfaces.c (face_inheritance_cycle)
(Finternal_set_lisp_face_attribute): Prevent infinite recursion if
a face is defined to inherit from itself (whaaat? how??!).
* src/xfaces.c (face_inheritance_cycle): New function.
(Finternal_set_lisp_face_attribute): Signal an error if the
':inherit' attribute of a face is modified in a way that will
cause it to inherit from itself. (Bug#79672)
* test/src/xfaces-tests.el (xfaces-test-circular-inheritance): New
test.
* etc/NEWS: Announce the incompatible change.
The case_Lisp_Int macro was originally introduced with different
definitions depending on USE_2_TAGS_FOR_INTS. However, since commit
2b57012478, we have assumed that USE_2_TAGS_FOR_INTS is always
defined, and the macro has only a single definition. As a result, the
macro is now unnecessary, and replacing it with standard C case labels
improves readability and understanding.
* src/lisp.h (case_Lisp_Int): Delete macro.
* src/alloc.c (process_mark_stack, survives_gc_p):
* src/data.c (Fcl_type_of):
* src/fns.c (value_cmp, sxhash_obj):
* src/pdumper.c (dump_object):
* src/print.c (print_object):
* src/xfaces.c (face_attr_equal_p): Remove uses of above macro.
Since the introduction of the 'calln' macro, the 'call1', 'call2', ...,
'call8' macros are just aliases for the former. This is slightly
misleading and potentially unhelpful. The number of arguments N can
also easily go out-of-synch with the used alias callN. There is no
reason not to replace these aliases with using 'calln' directly.
To reduce the risk for mistakes, the tool Coccinelle was used to make
these changes. See <https://coccinelle.gitlabpages.inria.fr/website/>.

Automatically redraw frames when we detect that a window
parameter used in a face filter is changed. (Bug#75291)

whole frame in this implementation, on face-relevant parameter
change
(syms_of_window): add window_auto_redraw_on_parameter_change
* src/xfaces.c (evaluate_face_filter): record properties
Add support for child frames on tty
The redisplay part is complete. The frame-handling part supports
use-cases like Posframe, Corfu, and child frames acting like tooltips.

This is based on a diff from 2024-10-15 which still applied.
Since then, I've inadvertantly modified the igc branch so that
it is no longer possible to get a clean diff of what has changed

It was an old alias for :inverse-video that hasn't worked very well for
many years.

* etc/NEWS: Announce.
* src/xfaces.c (recompute_basic_faces): Force complete
recalculation of non-ASCII faces and their fontsets if any
non-ASCII faces are in the frame's face cache. (Bug#72692)
* src/xfaces.c (recompute_basic_faces): Revert the change which
caused recalculation of all the faces, as it made cursor motion
too slow. Reported by Juri Linkov <juri@linkov.net> (bug#72692).
* src/image.c (free_image_cache): Unconditionally release image
cache, as this function is only called with its existence
already established.
* src/xfaces.c (free_frame_faces): Clear FRAME_IMAGE_CACHE (f).
(bug#71929)
* src/xfaces.c (free_realized_face): Always free realized face
structures, and avoid sending X requests when the display is not
available, not when it is.

image caches to individual frames rather than terminals.
* src/dispextern.h (struct image_cache) <scaling_col_width>: New
field.
* src/frame.c (gui_set_font): In lieu of clearing F's image
cache unconditionally, establish whether the column width as

with all new frames.
* src/xfaces.c (realize_face): Prevent rare crashes in
'uncache_face' because 'former_face' is NULL (i.e. the face
corresponding to 'former_face_id' is no longer cached).
(Bug#71243)
* src/xterm.c (x_dpyinfo): New function, which acts like
x_display_info_for_display except it always returns nonnull.
This simplifies callers and pacifies GCC 14. All callers changed.
* src/dispextern.h (enum face_underline_type): Indent and expand
commentary as to the new dependency on the order of its
enumerals.
* src/xfaces.c (realize_gui_face): Enable dots and dashes on
window systems.
* src/xterm.c (x_draw_underwave): Don't define unused variable
on Cairo builds.
(x_draw_dash): New function; implement for X and Cairo.
(x_fill_underline): New function. Delegate to x_fill_rectangle
or x_draw_dash as appropriate.

x_fill_rectangle.
* src/dispextern.h (face, face_underline_type, syms_of_xfacse)
(internal-set-lisp-face-attribute)
(gui_supports_face_attributes_p): Add definitions for new
underline styles of Double-line, Dots and Dashes. Rename
FACE_UNDER_LINE and FACE_UNDER_WAVE to make definitions
consistent. Delete tty_underline_p from the face struct and use
just underline going forward. Add a flag to check whether styled
underlines are available.
* lisp/cus-face.el (custom-face-attributes): Add entries for
Double-line, Dots and Dashes so they can be set through
`customize'.
* src/termchar.c (tty_display_info): Add an entry for the escape
sequence to set the underline style and color on terminal frames.
* src/term.c (init_tty, tty_capable_p, turn_on_face): Read and
save the underline style escape sequence from the Smulx termcap
(alternatively if the Su flag is set use a default sequence).
Allow checking for support of styled underlines in the current
terminal frame. Output the necessary escape sequences to activate
a styled underline on turn_on_face; this is currently only used
for the new special underline styles, a default straight underline
will still use the "us" termcap. Output escape sequence to set
underline color when set in the face and supported by the tty.
Save a default value for this sequence on init_tty when styled
underlines are supported.
* src/xfaces.c (tty_supports_face_attributes_p, realize_tty_face)
(map_tty_color): Assert whether styled underlines are supported by
the current terminal on display-supports-face-attributes-p checks.
Populate the correct underline style and color in the face spec
when realizing a face. Allow map_tty_color to map underline
colors alongside foreground and background. The interface of
map_tty_color was amended to allow the caller to supply the
underline color instead of accessing it through the face
attributes. (bug#62994)
* src/xterm.c (x_draw_glyph_string): Updated to use renamed
FACE_UNDERLINE_SINGLE and FACE_UNDERLINE_WAVE face_underline_type
enumerations.

* java/Makefile.in: Fix typos.
* java/org/gnu/emacs/EmacsFillRectangle.java (perform): Call

pointer deference.

[HAVE_ANDROID]: Define to their Android counterparts rather
than simulating their existence.

* src/image.c (image_bitmap_pixmap): Also enable when
HAVE_ANDROID.
* src/sfntfont-android.c (sfntfont_android_put_glyphs): Assert
that this is never called to draw a stippled background.
* src/xfaces.c (x_create_gc) [HAVE_ANDROID]: Redefine as
wrapper around android_create_gc.
(prepare_face_for_display) [HAVE_ANDROID]: Enable stipples.
* src/image.c (free_image):
* src/xfaces.c (free_realized_face): Handle scenarios where
free_frame_faces is called with the display connection cut.

unconditionally, lest fontsets for this dead frame contaminate
Vfontset_list and produce crashes afterwards. (bug#66151)
Be more systematic about putting space before paren in calls,
and in avoiding unnecessary parentheses in macros.
This was partly inspired by my wading through gcc -E output
while debugging something else, and seeing too many parens.
This patch does not change the generated .o files on my platform.
This saves several words in the hash table object at the cost of an
indirection at runtime. This seems to be a gain in overall
performance.
FIXME: We cache hash test objects in a rather clumsy way. A better
solution is sought.
* src/lisp.h (struct Lisp_Hash_Table): Use a pointer to the test
struct. All references adapted.
* src/alloc.c (garbage_collect):
* src/fns.c (struct hash_table_user_test, hash_table_user_tests)
(mark_fns, get_hash_table_user_test): New state for caching test
structs, and functions managing it.
These parameters have no visible semantics and are hardly ever used,
so just use the default values for all hash tables. This saves
memory, shrinks the external representation, and will improve
performance.
* src/fns.c (std_rehash_size, std_rehash_threshold): New.
(hash_index_size): Use std_rehash_threshold. Remove table argument.
All callers updated.
(make_hash_table): Remove rehash_size and rehash_threshold args.
All callers updated.
(maybe_resize_hash_table)
(Fhash_table_rehash_size, Fhash_table_rehash_threshold):
Use std_rehash_size and std_rehash_threshold.
(Fmake_hash_table): Ignore :rehash-size and :rehash-threshold args.
* src/lisp.h (struct Lisp_Hash_Table):
Remove rehash_size and rehash_threshold fields.
(DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE): Remove.
* src/lread.c (hash_table_from_plist): Don't read rehash-size or
rehash-threshold.
(syms_of_lread): Remove unused symbols.
* src/print.c (print_object): Don't print rehash-size or rehash-threshold.
* src/pdumper.c (dump_hash_table): Don't dump removed fields.
This takes less space (saves an entire word) and is more type-safe.
No change in behaviour.
* src/lisp.h (hash_table_weakness_t): New.
(struct Lisp_Hash_Table): Replace Lisp object `weak` with enum
`weakness`.
* src/fns.c
(keep_entry_p, hash_table_weakness_symbol): New.
(make_hash_table): Retype argument. All callers updated.
(sweep_weak_table, Fmake_hash_table, Fhash_table_weakness):
* src/alloc.c (purecopy_hash_table, purecopy, process_mark_stack):
* src/pdumper.c (dump_hash_table):
* src/print.c (print_object): Use retyped field.
