* | Fix string-to-syntax signature in comp-known-type-specifiersMattias Engdegård2022-08-181-1/+1
| | | | | | | | | | * lisp/emacs-lisp/comp.el (comp-known-type-specifiers): `string-to-syntax` can return nil.
* | * lisp/emacs-lisp/comp.el (comp-known-type-specifiers): Fix some typeAndrea Corallo2022-08-181-10/+10
| |
* | More non-nil-returning functions in source optimisationMattias Engdegård2022-08-181-5/+24
| | | | | | | | | | | | | | | | | | This change was partially generated and mechanically cross-validated with function type information from comp-known-type-specifiers in comp.el. * lisp/emacs-lisp/byte-opt.el (byte-compile-trueconstp): Extend list of functions and fix a typo (logxor).
* | Make GEN message from loaddefs-generate nicerLars Ingebrigtsen2022-08-181-1/+2
| | | | | | | | | | | | * lisp/emacs-lisp/loaddefs-gen.el (loaddefs-generate): Shorten the informational GEN file relative to the stated directory (bug#57265). This makes the message nicer for ELPA packages.
* | Improve cryptic syntax switch message in re-builderStefan Kangas2022-08-181-2/+2
| | | | | | | | | | | | | | * lisp/emacs-lisp/re-builder.el (reb-restart-font-lock): Move message from here... * lisp/emacs-lisp/re-builder.el (reb-change-syntax): ...to here. Change it to be less cryptic.

* | Improved `null` (alias `not`) optimisationMattias Engdegård2022-08-161-0/+11
| | | | | | | | | | | | Take static boolean information of the argument into account. * lisp/emacs-lisp/byte-opt.el (byte-optimize-not): New.
* | Improved `and` and `or` optimisationMattias Engdegård2022-08-161-27/+84
| | | | | | | | | | | | * lisp/emacs-lisp/byte-opt.el (byte-optimize-and, byte-optimize-or): Rewrite. Avoid branching on arguments statically known to be true or false, and hoist code out to an unconditional prefix when possible.
* | Improved `if` and `while` optimisationMattias Engdegård2022-08-161-38/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | Recognise some more special cases: (if X nil t) -> (not X) (if X t) -> (not (not X)) (if X t nil) -> (not (not X)) (if VAR VAR X...) -> (or VAR (progn X...)) * lisp/emacs-lisp/byte-opt.el (byte-opt-negate): New. (byte-optimize-if): Add transformations above and refactor. (byte-optimize-while): Better static nil-detection.
* | Improved static detection of nil and non-nil expressionsMattias Engdegård2022-08-161-21/+69

* | Fix variable types in warnings-suppressYury Kholodkov2022-08-151-2/+2
| | | | | | | | | | | | | | | | * lisp/emacs-lisp/warnings.el (warnings-suppress): The type of these user options is a list of lists of symbols, not a list of symbols (bug#57183). Copyright-paperwork-exempt: yes
* | Fix up the exclusion logic in loaddefs-generateLars Ingebrigtsen2022-08-151-10/+9
| | | | | | | | | | * lisp/emacs-lisp/loaddefs-gen.el (loaddefs-generate): Allow excluding files completely (bug#57144).
* | Tweak autoloads of defsubsts containing spaces/control charsLars Ingebrigtsen2022-08-151-1/+3
| | | | | | | | | | | | | | * lisp/emacs-lisp/loaddefs-gen.el (loaddefs-generate--print-form): Escape control chars in bodies so that we don't end up with trailing spaces if we're autoloading a defsubst containing "\\`[ \t\n\r]*\\'".
* | Further lisp-current-defun-name tweaksLars Ingebrigtsen2022-08-151-2/+7
| | | | | | | | | | | | * lisp/emacs-lisp/lisp-mode.el (lisp-current-defun-name): Further tweaks to make (autoload 'foo) work again. Perhaps this should all be reverted to the original version and then given a new rething.
* | * lisp/emacs-lisp/ring.el (ring): Define as a typeStefan Monnier2022-08-141-0/+4

(pcase--split-pred): Use it. * lisp/help-fns.el (help-fns-function-description-header): Use `functionp`. (help-fns--var-safe-local): Use `compiled-function-p`.
* | Strength-reduce apply with (list ...) as tail argumentMattias Engdegård2022-08-141-18/+19
| | | | | | | | | | * lisp/emacs-lisp/byte-opt.el (byte-optimize-apply): Transform (apply F ... (list X ...)) -> (funcall F ... X ...)

| | | | | | | | * lisp/emacs-lisp/nadvice.el (advice--interactive-form): Fix a typo.
* | nadvice.el: Avoid exponential blow up in interactive-form recursionStefan Monnier2022-08-131-13/+13
| | | | | | | | | | | | | | | | | | | | * lisp/emacs-lisp/nadvice.el (advice--interactive-form): Sink the call to `commandp` into the autoloaded function case since it's redundant in the other branch. (advice--make-interactive-form): Take just the interactive forms rather than the actual functions as arguments. (oclosure-interactive-form): Use `advice--interactive-form` rather than `commandp` since we'd call `advice--interactive-form` afterwards anyway.
* | Allow EXCLUDED-FILES in loaddefs-generate to be relativeLars Ingebrigtsen2022-08-131-0/+5
| | | | | | | | | | * lisp/emacs-lisp/loaddefs-gen.el (loaddefs-generate): Allow the excluded files to be relative (bug#57144).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisp/textmodes/emacs-authors-mode.el (emacs-authors-mode--hide-local-variables): Move from here... * lisp/emacs-lisp/subr-x.el (emacs-etc--hide-local-variables): ...to here. * lisp/textmodes/emacs-authors-mode.el (subr-x): Require. (emacs-authors-mode): Use above renamed function. * lisp/textmodes/emacs-news-mode.el (subr-x): Require. (emacs-news--mode-common): Call 'emacs-etc--hide-local-variables' to hide local variables section.
* | Don't update loaddefs.el timestamps uselessly in loaddefs-generateLars Ingebrigtsen2022-08-121-4/+8
| | | | | | | | | | * lisp/emacs-lisp/loaddefs-gen.el (loaddefs-generate): Don't re-write the loaddefs.el file when there's no reason to.
* | Further seq-uniq speed-ups for listsLars Ingebrigtsen2022-08-121-5/+15
| | | | | | | | | | * lisp/emacs-lisp/seq.el (seq-uniq): Speed up more for long lists (bug#57079).
* | Use help-key-binding face in package list helpStefan Kangas2022-08-121-1/+1
| | | | | | | | | | * lisp/emacs-lisp/package.el (package--prettify-quick-help-key): Use help-key-binding face.
* | ; Fix documentation of 'loaddefs-generate' (bug#57144)Eli Zaretskii2022-08-121-6/+12
| | | | | | | | * lisp/emacs-lisp/loaddefs-gen.el (loaddefs-generate): Doc fix.
* | Make ad-version variable obsoleteStefan Kangas2022-08-111-2/+3
| | | | | | | | | | * lisp/emacs-lisp/advice.el (ad-version): Make obsolete in favor of emacs-version. It has not been bumped since 1994.
* | Don't show status message in Helper-describe-bindingsStefan Kangas2022-08-111-1/+0
| | | | | | | | | | * lisp/emacs-lisp/helper.el (Helper-describe-bindings): Don't show status message.
* | ; * lisp/emacs-lisp/subr-x.el (string-pad): Optimise.Mattias Engdegård2022-08-101-7/+3
| |
* | Extend LAP optimisations to more operationsMattias Engdegård2022-08-101-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | Delete dead code in checkdoc.elStefan Kangas2022-08-101-20/+1
| | | | | | | | | | * lisp/emacs-lisp/checkdoc.el: Delete code commented out since 1997.
* | Autoload string-blank-pStefan Kangas2022-08-091-0/+1
| | | | | | | | | | | | * lisp/eshell/em-hist.el (subr-x): * lisp/net/eudc.el (subr-x): Don't require. * lisp/emacs-lisp/subr-x.el (string-blank-p): Autoload.
* | Further lisp-current-defun-name tweaksLars Ingebrigtsen2022-08-091-1/+1
| | | | | | | | | | * lisp/emacs-lisp/lisp-mode.el (lisp-current-defun-name): Tweak so that cl-defmethod and friends work again.
* | Add a faster seq-uniq for listsLars Ingebrigtsen2022-08-091-0/+17
| | | | | | | | | | * lisp/emacs-lisp/seq.el (seq-uniq): Add a faster method for lists (bug#57079).
* | Make the loaddefs.el file slightly shorterLars Ingebrigtsen2022-08-091-18/+28
| | | | | | | | | | | | | | | | * 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.
* | Another lisp-current-defun-name tweakMichael Heerdegen2022-08-091-1/+1
| | | | | | | | | | * lisp/emacs-lisp/lisp-mode.el (lisp-current-defun-name): Avoid error when edebug spec is the symbol t.
* | Further lisp-current-defun-name tweaksLars Ingebrigtsen2022-08-081-2/+6
| | | | | | | | | | * lisp/emacs-lisp/lisp-mode.el (lisp-current-defun-name): Further tweaks to finding the symbol being defined (defalias).
* | Allow specifying how args are to be stored in `command-history'Lars Ingebrigtsen2022-08-081-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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'.
* | Make which-func-mode output less junkLars Ingebrigtsen2022-08-081-18/+46
| | | | | | | | | | | | | | * 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).
