it is already known that USE_X_TOOLKIT is defined.

Make some C symbols static if they don’t need to be extern.

This is mostly a cleanup patch to fix growing discrepancies
between src/lisp.h and configure.ac in terms of how they deduce
how EMACS_INT aligns. The patch includes a static check that the
two methods now agree. It also speeds up ‘configure’ a bit.
* configure.ac (ALIGNOF_INT, ALIGNOF_LONG, ALIGNOF_LONG_LONG):
Remove; no longer used.
(ALIGNOF_EMACS_INT): New macro.
(system_malloc): Set to 'no' more consistently with what’s
in src/lisp.h.
* src/lisp.h (ALIGNOF_EMACS_INT): Do not define here, as config.h
defines it now. Check that config.h’s definition equals the
actual alignof (EMACS_INT).
(USE_USB_TAG): Set more consistently with what’s in configure.ac.
(alignas): Don’t second-guess Gnulib.
|
| |

|

* src/ccl.c: The bug occurs in GCC versions after GCC 13.
|
| |
|
|
|
|
|
|
|
|
|
| |
* src/alloc.c, src/gmalloc.c: Include <malloc.h> before <stdlib.h>.
This mimics include patterns elsewhere, and avoids a problem if
malloc.h declares realloc (i.e., rpl_realloc) early as extern,
whereas Gnulib stdlib.h declares it later as inline which means it
is extern inline, which clashes with gmalloc’s definition of
rpl_realloc when gmalloc.o is used. Problem discovered when
building Emacs on Ubuntu 25.10 with "./configure CC='gcc -m32'
emacs_cv_struct_alignment=no gl_cv_header_working_stdalign_h=no".
|
| |
|
|
|
| |
* src/ralloc.c (find_heap, update_heap_bloc_correspondence):
Omit unnecessary comparisons to NULL that cause GCC to warn.
|
| |
|
|
|
|
| |
* src/sound.c (Fw32_sound_volume): New function.
* etc/NEWS: Announce it.

* src/frame.c (store_frame_param): Make sure 'minibuffer',
'parent-frame' and 'delete-before' parameters reference frame on
same terminal. Spare GUI frames when checking root frames of
tty frames and their surrogate minibuffer frames (Bug#79947).

The empty vector and string(s) are immutable, contain no references and
always read as the same objects.
* src/print.c (PRINT_CIRCLE_CANDIDATE_P): Turn macro into...

|

| |
| |
| |
| |
| |
| |

* src/nsterm.m ([EmacsWindow initWithEmacsFrame:fullscreen:screen:]):
Always show the toolbar below the window title. This is needed on
Mac OS 11+ where the toolbar style is decided by the system (which
is unpredictable) and the newfangled "compact" toolbar may be chosen
(which is undesirable). (Bug#79900)
|
| | |
| |
| |
| |
| | |
* src/font.c (font_match_p): Avoid assertion violations in
'font_encode_char' if FONT is not a font-object.
|
| | |
| |
| |
| |
| |
| |
| | |
Also, add more commentary about the situation.
* src/systhread.h (SYSTHREAD_ALIGN_ROOM): Use alignof (double),
not alignof (int), to align the room. This means we have
only 8 (not 12) bytes of slop on 32-bit HPPA GNU/Linux.

On this platform, you cannot reliably malloc objects containing
values of type pthread_mutex_t or pthread_cond_t, since malloc
guarantees only 8-byte alignment but these two types require
16-byte alignment. See GCC bug 115750
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115750> reported by
Sam James and Emacs bug 79936 <https://bugs.gnu.org/79936>
reported by John Paul Adrian Glaubitz.
* configure.ac (ALIGNOF_MAX_ALIGN_T, ALIGNOF_PTHREAD_COND_T)
(ALIGNOF_PTHREAD_MUTEX_T) [HAVE_PTHREAD]: New C macros.
* src/systhread.c (sys_mutex_init, sys_mutex_lock)
(sys_mutex_unlock, sys_cond_init, sys_cond_wait)
(sys_cond_signal, sys_cond_broadcast, sys_cond_destroy):
Use SYTHREAD_ALIGN_PTR to convert sys_mutex_t and sys_cond_t to
pthread_mutex_t and pthread_cond_t, since runtime conversion is
needed on GNU/Linux HPPA.
* src/systhread.h (SYSTHREAD_ALIGN_ROOM, SYSTHREAD_ALIGN_PTR):
New macros, which affect the generated code only on
unusual platforms like GNU/Linux HPPA.
(sys_mutex_t, sys_cond_t) [HAVE_PTHREAD]: Use them.

when they are followed by ‘;’. All uses changed.

* lisp/vc/vc-hooks.el (vc-file-setprop): Use cl-pushnew.

'always', 'ask', 'ask-dir' (bug#79862).

| |
| |
| |
| |
| |

* lisp/treesit.el (treesit-auto-install-grammar): Add the value 'ask-dir'.
(treesit-ensure-installed): When 'treesit-auto-install-grammar' is
'ask' or 'ask-dir', ask for the directory to install the grammar library
using the first writable directory of 'treesit-extra-load-path' as default.
Also add the provided directory to 'treesit-extra-load-path' afterwards.
* src/treesit.c (treesit-extra-load-path): In the docstring
mention the fact that the first directory is special (bug#79862).

Problem reported by John Paul Adrian Glaubitz (bug#79876).
* src/data.c (Fash): Don’t assume stdc_leading_zeros, which
returns an unsigned integer of unspecified width, returns
a value narrower than EMACS_INT. Also, don’t munge the code to
worry about stdc_leading_zeros (0); unlike GCC’s __builtin_clz,
stdc_leading_zeros works fine on 0. And use a temporary to
avoid a cast.

Problem reported by Helmut Eller (bug#79886).
* src/lisp.h (USE_LSB_TAG): Adjust to alignas changes.
(alignas): For GCC and Clang, prefer __attribute__ ((__aligned__ (A)))
to alignas (A) even if the compiler claims to support the latter.
This works around a bug in GCC 14 i386 C23 alignas.
No need to worry about whether __alignas_is_defined is defined.

We dropped support for MSVC long ago, and nowadays only support
MinGW for the MS-Windows builds of Emacs.
* src/w32term.h:
* src/w32fns.c:
* src/w32.c:
* nt/inc/sys/socket.h:
* nt/inc/stdalign.h:
* nt/inc/ms-w32.h: Remove MSVC-specific code and preprocessor
conditions.
* nt/inc/ms-w32.h: Don't redirect Posix functions to MS _FOO
equivalents, as MinGW headers do that nowadays better, not
necessarily via functions, and do not disable that when __STDC__
is defined.

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.

Assuming ATTRIBUTE_PURE means that the function must return,
a few more functions that should not be declared with ATTRIBUTE_PURE.
The GCC manual (and even the C23 standard, with [[reproducible]])
is not clear about this, and it’s better to be safe.
* src/bignum.h (mpz_get_d_rounded):
* src/lisp.h (bignum_to_double):
No longer pure, as it does not return if memory is exhausted.
* src/fns.c (Fproper_list_p): No longer pure, as it does not
return if the user quits.
* src/gnutls.c (Fgnutls_errorp): No longer pure, as it does not
return if it runs into an eassert failure in XSYMBOL_WITH_POS via EQ.
* src/lisp.h (bignum_to_intmax, bignum_to_uintmax, bignum_bufsize):
No longer pure, as it does not return if it runs into an
eassert failure in XBIGNUM via xbignum_val.

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/keyboard.c (make_lispy_position): When calculating a
position in the left margin skip any scroll bar on the left of
