* Edebug: Make it possible to debug `gv-expander`s in `declare`Stefan Monnier2021-02-124-4/+30
| | | | | | | | | | | | | | | | | Arrange for declarations to be able to specify their own specs via the `edebug-declaration-spec` property. * lisp/emacs-lisp/edebug.el: (edebug--get-declare-spec): New function. (def-declarations): New spec element. (defun, defmacro): Use it in their spec. * lisp/emacs-lisp/gv.el (gv-expander, gv-setter): Set `edebug-declaration-spec`. * test/lisp/emacs-lisp/edebug-tests.el (edebug-tests-gv-expander): New test. * test/lisp/emacs-lisp/edebug-resources/edebug-test-code.el (edebug-test-code-use-gv-expander): New test case.
* Comment out mysterious code from cperl-mode.elStefan Kangas2021-02-131-3/+6
| | | | | | | * lisp/progmodes/cperl-mode.el: Comment out mysterious code referring to some unknown variable 'edit-var-mode-alist'. No one seems to know what it is used for, so comment it out and see if anyone complains before Emacs 28.1 or 28.2.
* Remove outdated documentation from cperl-mode.elStefan Kangas2021-02-131-57/+12
| | | | | | | | * lisp/progmodes/cperl-mode.el (cperl-tips, cperl-problems) (cperl-praise, cperl-speed, cperl-mode): Doc fixes; remove references to very old versions of Emacs and other "Emaxen". (cperl-problems-old-emaxen): Make obsolete and remove information on Emacs 20.3 and older.
* Edebug: Overload `edebug-form-spec` even lessStefan Monnier2021-02-1210-238/+273
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `edebug-form-spec` symbol property was used both to map forms's head symbol to the corresponding spec, and to map spec element names to their expansion. This lead to name conflicts which break instrumentation of examples such as (cl-flet ((gate (x) x)) (gate 4)) because of the Edebug spec element `gate`. So introduce a new symbol property `edebug-elem-spec`. * lisp/subr.el (def-edebug-elem-spec): New function. * lisp/emacs-lisp/edebug.el (edebug--get-elem-spec): New function. (edebug-match-symbol): Use it. (Core Edebug elems): Put them on `edebug-elem-spec` instead of `edebug-form-spec`. (ELisp special forms): Set their `edebug-form-spec` via dolist. (Other non-core Edebug elems): Use `def-edebug-elem-spec`. (edebug-\`): Use `declare`. * lisp/emacs-lisp/pcase.el (pcase-PAT, pcase-FUN, pcase-QPAT): * lisp/skeleton.el (skeleton-edebug-spec): * lisp/emacs-lisp/cl-macs.el: Use `def-edebug-elem-spec`. * test/lisp/emacs-lisp/edebug-tests.el (edebug-tests--conflicting-internal-names): New test. * test/lisp/emacs-lisp/edebug-resources/edebug-test-code.el (edebug-test-code-cl-flet1): New test case. * doc/lispref/edebug.texi (Specification List): Add `def-edebug-elem-spec`. (Specification Examples): Use it. * doc/lispref/loading.texi (Hooks for Loading): Avoid the use of `def-edebug-spec` in example (better use `debug` declaration).
* Remove XEmacs and Emacs 21 compat code from cperl-modeStefan Kangas2021-02-131-19/+20
| | | | | | | * lisp/progmodes/cperl-mode.el (cperl-mode): Remove XEmacs and Emacs 21 compat code. (cperl-compilation-error-regexp-list): New variable. (cperl-compilation-error-regexp-alist): Make obsolete.

* Simplify expression in byte-code decompilerMattias Engdegård2021-02-121-4/+1
| | | | | * lisp/emacs-lisp/byte-opt.el (byte-decompile-bytecode-1): Replace roundabout expression with what it essentially does.
* byte-opt.el: More concise expressionMattias Engdegård2021-02-121-10/+9
| | | | | * lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker): Refactor `setq` clause.
* Avoid traversing dead `if` branches in bytecode optimiserMattias Engdegård2021-02-121-32/+32
| | | | | | | | | | | | | | | | | | | | There is no point in traversing conditional branches that are statically known never to be executed. This saves some optimisation effort, but more importantly prevents variable assignments and references in those branches from blocking effective constant propagation. Also attempt to traverse as much as possible in an unconditional context, which enables constant-propagation through (linear) assignments. * lisp/emacs-lisp/byte-opt.el (byte-optimize-form): Rewrite the (tail) recursion into an explicit loop. Normalise a return value of (quote nil) to nil, for easier subsequent optimisations. * lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker): Don't traverse dead `if` branches. Use unconditional traversion context when possible.
* Don't inline tramp-debug-messageMattias Engdegård2021-02-121-1/+1
| | | | | | | * lisp/net/tramp.el (tramp-debug-message): Change defsubst into defun. Until now the byte-compiler hasn't been clever enough to inline this function but this is about to change; the code expansion is unnecessary and makes compiler improvements more difficult to gauge.

(edebug-cancel-on-entry): Rename from `cancel-edebug-on-entry`. (edebug-global-prefix): Rename from `global-edebug-prefix`. (edebug-global-map): Rename from `global-edebug-map`. * lisp/emacs-lisp/pcase.el (pcase-PAT): Remove `let`. (let): Use `declare` instead. (pcase--edebug-match-macro): Use new name `edebug-get-spec`.

* Make recursive minibuffers and recursive edits work togetherAlan Mackenzie2021-02-115-59/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * lisp/minibuffer.el (exit-minibuffer): When in a minibuffer, throw an error should the command loop nesting level be wrong. * src/lisp.h (minibuffer_quit_level): declare as an extern. (command_loop_level): Move definition from src/window.h * src/window.h (command_loop_level): move definition to src/lisp.h. * src/eval.c (minibuffer_quit_level): Move this variable to file level from being a static inside internal_catch. (internal_catch): Simplify the logic. * src/minibuf.c (Vcommand_loop_level_list): New variable. (move_minibuffer_onto_frame): Set the major mode of *Minibuf-0*. (Fminibuffer_innermost_command_loop_p): New primitive. (Fabort_minibuffers): Check the command loop level before throwing t to 'exit, and set minibuffer_quit_level too. (read_minibuf): New variable calling_window. Before stacking up minibuffers on the current mini-window, check that the mini-window is not the current one. Do not call choose_minibuf_frame from read_minibuf's unwinding process. Bind calling_frame and calling_window over the recursive edit. Set the new minibuffer's major mode directly. Remove the switching away from the minibuffer after the recursive edit. (get_minibuffer): Record the command loop level in new variable Vcommand_loop_level_list. No longer set the major mode of a returned minibuffer. (minibuf_c_loop_level): New function. (read_minibuf_unwind): New variables calling_frame, calling_window are unbound from the binding stack. Remove old variable `window', which could not be set reliably to the expired mini-window. The expired minibuffer is determined as the nth in the list, rather than the contents of the current or previous mini-window. Switch the current window away from the mini-window here (moved from read_minibuf).
