This change drastically reduce compile time. Apparently GCC optimizer
does not scale up well at all for long sequences of assignments into a
single array.

* src/comp.c (gcc_jit_context_new_string_literal)
(gcc_jit_block_add_assignment_op): New imports.
(comp_t): New 'size_t_type' 'memcpy' fields.
(emit_static_object): Define static objects using string literals
and memcpy.
(define_memcpy): New function.
(Fcomp__init_ctxt): Define 'size_t_type' and 'memcpy'.
* 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'.
Make the navigation in the occur buffer closer
to the navigation in the compilation buffer.
Add bindings to navigate the occur matches (Bug#39121).
Honor `next-error-highlight' and `next-error-highlight-no-select'
when navigating the occurrences.
* lisp/replace.el (occur-highlight-regexp, occur-highlight-overlay):
New variables.
(occur-1): Set `occur-highlight-regexp' to the searched regexp.
(occur-goto-locus-delete-o, occur--highlight-occurrence): New defuns.
(occur-mode-display-occurrence, occur-mode-goto-occurrence):
Use `occur--highlight-occurrence'.
(occur-mode-map): Bind n to `next-error-no-select'
and p to `previous-error-no-select'
* etc/NEWS (Changes in Specialized Modes and Packages in Emacs 28.1):
Announce this change.
* test/lisp/replace-tests.el (replace-tests-with-highlighted-occurrence):
Add helper macro.
(occur-highlight-occurrence): Add test.
loadup.el calls `native-comp-available-p', that calls
load_gccjit_if_necessary() in Windows. That function tries to load
libgccjit using the mappings defined in `dynamic-library-alist'. That
mapping is filled by term/w32-win.el, but that file may be loaded too
late.
* src/emacs.c (syms_of_emacs): Add libgccjit to the
`dynamic-library-alist' used when starting to dump so
`native-comp-available-p' always works in Windows.
This happened when subr.eln was not the first native compilation unit
to be loaded. register_native_comp_unit() is called when loading a
native compilation unit and that in turn used to call `gensym', which
was not loaded yet. This led to a SIGSEGV.
* src/comp.c (register_native_comp_unit): Replace the call to `gensym'
with an ad-hoc counter.
* lisp/tab-bar.el (switch-to-buffer-other-tab): Use
'window-normalize-buffer-to-switch-to' on 'buffer-or-name',
like does 'pop-to-buffer' used by 'switch-to-buffer-other-frame',
instead of raising the error "Invalid buffer" on a non-existent buffer name.
This fixes the use case when, for example, 'find-file-hooks'
fails.
* lisp/files.el (find-alternate-file): If buffer 'oname' exists,
kill it before renaming the new one. (Bug#41359)
* 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.
Being quite early in startup initialization is better not to rely on
Ffile_exists_p, this call Ffile_expand and not all the necessary
initialization already happened.
* src/pdumper.c (dump_do_dump_relocation): Use fopen instead of
Ffile_exists_p.
* 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)
(calculate-lisp-indent): To distinguish code and data when indenting,
introduce the convention that a space between an open paren and
a symbol indicate that this should be indented as a simple data list.
* lisp/ido.el (ido-make-buffer-list-1):
Create a buffer-local binding to improve performance when a lot of
buffers are open (bug#41029).
Copyright-paperwork-exempt: yes
The existing ITRANS scheme did not support some characters and
language quirks like 'chillu's. The Inscript method had errors.
* lisp/language/ind-util.el (indian-mlm-base-table): Add archaic
chars, Mozhi combos; cleanup.
(indian-mlm-mozhi-table): New scheme Mozhi.
* lisp/leim/quail/indian.el (inscript-mlm-keytable): Correct
errors. Add Inscript chillus & zero-width chars, Mozhi scheme.
* etc/NEWS: Mention the changes.
* 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.
