Extend the set of eligible opcodes for certain peephole
transformations, which then provide further optimisation
opportunities.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-lapcode):
Optimise empty save-current-buffer in the same way as we already
do for save-excursion and save-restriction. This is safe
because (save-current-buffer) is a no-op.
(byte-compile-side-effect-and-error-free-ops): Add list3, list4 and
listN. These were all apparent oversights as list1 and list2 were
already included.
(byte-after-unbind-ops): Add stack-ref, stack-set, discard, list3,
list4 and listN. Stack manipulation is safe because unbind cannot
read or modify stack entries.
* lisp/emacs-lisp/loaddefs-gen.el
(loaddefs-generate--shorten-autoload): New function.
(loaddefs-generate--make-autoload): Use it to drop optional nil
values from the `autoloads' forms. This makes the loaddefs.el
file about 12K shorter.
* doc/lispref/functions.texi (Declare Form): Document
`interactive-args'
* lisp/replace.el (replace-string): Store the correct interactive
arguments (bug#45607).
* lisp/emacs-lisp/byte-run.el (byte-run--set-interactive-args):
New function.
(defun-declarations-alist): Use it.
* src/callint.c (fix_command): Remove the old hack (which now
longer works since interactive specs are byte-compiled) and
instead rely on `interactive-args'.
* lisp/emacs-lisp/lisp-mode.el (lisp-current-defun-name): Use
edebug specs to find the name (if they exist), and default to
returning the top-level symbol if there isn't a define-like form
(bug#49592).
'User variables' were made obsolete in Emacs 24 along with
user-variable-p; the sign of the position in (#$ . POS) hasn't
mattered since.
* lisp/emacs-lisp/bytecomp.el (byte-compile-output-docform):
Don't emit negative position when doc string starts with `*`.
* src/lread.c (get_lazy_string): Explain.
* lisp/emacs-lisp/loaddefs-gen.el (autoload-ignored-definitions):
Add another semantic function.
(loaddefs-generate--compute-prefixes): Allow newline after the "(def*"
form. (Bug#57000)
https://mail.gnu.org/archive/html/emacs-devel/2022-07/msg01127.html
points out that end-users can get bitten by this, accidentally
calling `timer-activate` on an already activated timer.
* lisp/emacs-lisp/timer.el (timer--activate): Signal an error if we try
to re-add a timer that's already on the timer-list.
* lisp/emacs-lisp/bytecomp.el (byte-compile-output-docform): Don't
insert a \n before the #@ docstrings since make-docfile doesn't scan
.elc files any more.
* lisp/emacs-lisp/loaddefs-gen.el
(loaddefs-generate--compute-prefixes): Allow tabs and spaces before
symbol name, so that "(defvar\tfoo-bar nil)" is properly picked up.
Before this change, such a definition would be wrongly picked up as
the symbol "nil".
* lisp/subr.el (package--builtin-versions): Adjust comments.
* lisp/emacs-lisp/loaddefs-gen.el (no-update-autoloads): Moved
here from autoload.el.
* lisp/emacs-lisp/loaddefs-gen.el: Removed now that it's no longer
used.
* lisp/emacs-lisp/package.el
(package-autoload-ensure-default-file): Don't warn about
soon-to-be obsolete functon.
* lisp/Makefile.in (all): Add "autoloads", which now otherwise
won't be done.
($(lisp)/loaddefs.el): Remove this target, since it's always done,
and would then trigger a re-compilation of loaddefs.elc.
* lisp/loadup.el: Load loaddefs.elc (if it exists).
* lisp/emacs-lisp/loaddefs-gen.el (loaddefs-generate): Don't
include no-byte-compile cookies in the Emacs build.
* src/Makefile.in ($(pdmp)): Depend on loaddefs.elc to ensure that
it's built by this point.
($(etc)/DOC): Don't scan loaddefs.el for doc strings, since they
are now picked up from the .elc file (bug#53024).
* lisp/emacs-lisp/eldoc.el
(eldoc-display-message-no-interference-p): Don't disable eldoc
when edebugging (bug#56459). There should be no interference in
that case, because edebug messaging is done after stepping, and
eldoc messaging is done after other movements.
* src/editfns.c (narrow_to_region_internal): New function, which
contains the body previously in 'Fnarrow_to_region' but accepts
a third argument.
(Fnarrow_to_region): Use the new function. Update the docstring.
(Fwiden): Update the docstring.
* src/lisp.h: Prototype of the new function.
* src/xdisp.c (handle_fontified_prop): Use the new function instead
of 'Fnarrow_to_region'.
* src/process.c (Finternal_default_process_filter):
* src/lread.c (readevalloop): Remove the third argument to
'Fnarrow_to_region'.
* src/bytecode.c (exec_byte_code):
* lisp/emacs-lisp/comp.el (comp-limplify-lap-inst):
* lisp/emacs-lisp/bytecomp.el: Restore the statu quo ante.
* etc/NEWS: Remove the entry about the new optional argument.
* doc/lispref/positions.texi (Narrowing): Update the documentation.
* lisp/emacs-lisp/ert.el (ert-write-junit-test-summary-report):
* lisp/emacs-lisp/shortdoc.el (file):
* lisp/find-lisp.el (find-lisp-find-dired-insert-file):
* lisp/progmodes/hideif.el (hide-ifdefs):
* lisp/tar-mode.el (tar-subfile-save-buffer):
Prefer nil or omitted arg to (current-time) where this is better
or more-efficient.
* lisp/emacs-lisp/rx.el (rx--to-expr, rx--pcase-transform):
Don't autoload.
(rx--pcase-macroexpander): Extract body into...
(rx--pcase-expand): ...a separate function, which is autoloaded.
* lisp/emacs-lisp/cl-macs.el (cl--optimize)
(cl-struct-sequence-type, cl-struct-slot-offset): Autoload since
they are referred to by code in cl-loaddefs.el.
* lisp/emacs-lisp/package.el (package-directory-list)
(package-quickstart-file): Specify group to avoid warning when
byte-compiling loaddefs.el.
(package-activated-list): Autoload since we're assigning the
variable from a function completely autoloaded.
