* src/lisp.h (struct handler): Remove unused 'bytecode_offset' field,
which was added at some point while prototyping.
* src/bytecode.c (UPDATE_OFFSET): Subtract 1, so the offset is accurate.
* src/eval.c (record_in_backtrace): Use 'backtrace_top' instead of
'backtrace_next', and check that 'backtrace_byte_offset' > 0 before
calling it, so the specbinding stack isn't scanned just to store an
invalid offset.
* src/lisp.h:
* src/eval.c (backtrace_byte_offset): Remove global variable, and
put it...
* src/thread.h (thread_state): ...in here as
m_backtrace_byte_offset, and define backtrace_byte_offset as a
macro that points to it.
* src/bytecode.c (UPDATE_OFFSET): Move out of #ifdef
BYTE_CODE_THREADED.
* lisp/language/misc-lang.el (composition-function-table): Reorder
Arabic composition rules in descending order of lookback.
* src/composite.c (syms_of_composite): Document the order of rules
in 'composition-function-table'.
Simplified version of a patch from Pip Cet (Bug#41321#299).
* src/alloc.c (maybe_lisp_pointer): Remove. All uses removed.
(mark_memory): Also look at the pointer offset by ‘lispsym’,
for symbols.
* src/xdisp.c (Fline_pixel_height, Fmove_point_visually): Save and
restore the bidi cache, to avoid inadvertently resetting it by
starting a new iteration through buffer text. This could cause
trouble if these functions are called during a redisplay cycle,
especially while we were processing RTL text.
If automatic character composition triggers GC, and
'garbage-collection-messages' are turned on, we could have the
bidi cache reset while processing RTL text, which would then
consistently crash.
* src/xdisp.c (display_echo_area_1): Protect the bidi cache
against changes inside 'try_window'.
* src/sysdep.c (emacs_exec_file): Don't compile this function
anymore on WINDOWSNT, since it is not used there. This function
was the only reason for having 'execve' prototype in ms-w32.h.
* nt/inc/ms-w32.h (execve): Remove prototype and the MinGW64 vs
ming.org mess that it causes.
* src/xdisp.c (redisplay_internal): Don't use "optimization 1"
if a glyph row from which to start display begins with a display
property that draws into the fringes. (Bug#41584)
* src/xdisp.c (try_window_id): Don't use this optimization if a
glyph row from which to start display begins with a display
property that draws into the fringes. (Bug#41584)
* lisp/international/mule.el (define-coding-system):
Require :pre-write-conversion and :post-read-conversion functions
to leave the match data untouched.
* src/coding.c (Fdecode_coding_string, Fencode_coding_string):
Document functions as match-data-preserving.

* src/lread.c (read_vector): If the vector is to short to be for

might run past the end of the vector.
* configure.ac: Clarify wording for --with-wide-int help.
* src/pdumper.c (dump_vectorlike_generic):
Do the eassert even if --with-wide-int was specified unnecessarily.
Performance issue reported by Eli Zaretskii (Bug#41321#149).
* src/alloc.c (GC_OBJECT_ALIGNMENT_MINIMUM): New constant.
(maybe_lisp_pointer): Use it instead of GCALIGNMENT.
* src/lisp.h (struct Lisp_Float): Declare via
GCALIGNED_UNION_MEMBER, not via GCALIGNED_STRUCT, since alloc.c
creates these in arrays and GCALIGNED_STRUCT does not necessarily
suffice to align struct Lisp_Float when it’s used in an array.
This avoids undefined behavior on oddball machines where
sizeof (struct Lisp_Float) is not a multiple of 8 and the compiler
does not support __attribute__ ((aligned 8)).
* src/alloc.c (union emacs_align_type): Move to here ...
* src/lisp.h: ... from here, and uncomment out some of the
types that alloc.c can see but lisp.h cannot.
* src/alloc.c (MALLOC_ALIGNMENT_BOUND): Remove.
(LISP_ALIGNMENT): Go back to yesterday’s version, except use
union emacs_align_type instead of max_align_t.
(MALLOC_IS_LISP_ALIGNED): Go back to yesterday’s version.
(maybe_lisp_pointer): Check against GCALIGNMENT, not LISP_ALIGNMENT.
* src/lisp.h (union emacs_align_type): Bring back.
This is simpler, and fixes a bug in the previous fix.
* src/alloc.c (MALLOC_ALIGNMENT_BOUND): Simplify by
using max_align_t, since the buggy implementations won’t
break this simpler implementation.
(LISP_ALIGNMENT): Simplify by just using GCALIGNMENT, since the
fancier implementation wasn’t correct anyway, and fixing it
isn’t worth the trouble on practical platforms.
* src/lisp.h (union emacs_align_type): Remove.
Problem reported by Eli Zaretskii (Bug#41321).
* src/alloc.c (MALLOC_ALIGNMENT_BOUND): New constant.
(LISP_ALIGNMENT): Lower it to avoid crashes on MinGW and similarly
buggy platforms where malloc returns pointers not aligned to
alignof (max_align_t). But keep it higher on platforms where this
is known to work, as it helps GC performance.
(MALLOC_IS_LISP_ALIGNED): Define in terms of the other two.
* src/alloc.c (stacktop_sentry):
* src/thread.c (run_thread):
Don’t overalign or oversize stack sentries; they need to be
aligned only for pointers and Lisp_Object, not for arbitrary
pseudovector contents.
* src/lisp.h (union emacs_align_type): New type, used for
LISP_ALIGNMENT.
* src/xdisp.c (get_visually_first_element)
(Fbidi_find_overridden_directionality):
* src/cmds.c (Fend_of_line): Use FETCH_BYTE instead of FETCH_CHAR,
and byte position instead of character position, to access
individual bytes of buffer text. This avoids producing invalid
characters and accessing wrong buffer positions. (Bug#41520)

(cherry picked from commit 3d1bcfba5e)
Check Lisp_Compiled objects better as they’re created,
so that the byte-code interpreter needn’t do the checks
each time it executes them. This improved performance
of ‘make compile-always’ by 1.5% on my platform. Also,
improve the quality of the (still-incomplete) checks, as
this is more practical now that they’re done less often.
* src/alloc.c (make_byte_code): Remove. All uses removed.
(Fmake_byte_code): Put a better (though still incomplete)
check here instead. Simplify by using Fvector instead
of make_uninit_vector followed by memcpy, and by using
XSETPVECTYPE instead of make_byte_code followed by XSETCOMPILED.
* src/bytecode.c (Fbyte_code): Do sanity check and conditional
translation to unibyte here instead of each time the function is
executed.
(exec_byte_code): Omit no-longer-necessary sanity and
unibyte checking. Use SCHARS instead of SBYTES where
either will do, as SCHARS is faster.
* src/eval.c (fetch_and_exec_byte_code): New function.
(funcall_lambda): Use it.
(funcall_lambda, lambda_arity, Ffetch_bytecode):
Omit no-longer-necessary sanity checks.
(Ffetch_bytecode): Add sanity check if actually fetching.
* src/lisp.h (XSETCOMPILED): Remove. All uses removed.
* src/lread.c (read1): Check byte-code objects more thoroughly,
albeit still incompletely, and do translation to unibyte here
instead of each time the function is executed.
(read1): Use XSETPVECYPE instead of make_byte_code.
(read_vector): Omit no-longer-necessary sanity check.
* src/fns.c (Ffillarray, Fclear_string):
Add CHECK_IMPURE here, to be consistent with Faset etc.
(Ffillarray): Prefer memset when the fill is a single byte.
* lisp/version.el: Don’t put an RCS Id style string into the
executable via purecopy, as this does not work with the pdumper.
* src/emacs.c (RCS_Id): New constant, for 'ident'.
It has been missing since 2012-07-03 (Emacs 24.3)

(Fbuffer_local_variables): Explicitly add buffer-undo-list.
* src/alloc.c (SET_STACK_TOP_ADDRESS): Do not call
__builtin_unwind_init.
(flush_stack_call_func1): Rename from 'flush_stack_call_func'.
(flush_stack_call_func): New function to spill all registers
before calling 'flush_stack_call_func1'. This to make sure the
top of the stack identified includes those registers.
