* Disable -Wclobbered around exec_byte_code (bug#79610)scratch/exec-byte-codeMattias Engdegård2025-10-171-15/+13
| | | | | | | * src/bytecode.c (exec_byte_code): The old hack for working around spurious -Wclobbered warnings from GCC no longer suffices; disable the warning locally. This also makes the code slightly smaller and faster.
* ; exec_byte_code: refactor branch caseMattias Engdegård2025-10-161-14/+14

* exec_byte_code: use fixed registers for top and pc (bug#79610)Mattias Engdegård2025-10-161-2/+16
| | | | | | | | | | | | | GCC seems to have difficulty allocating important global interpreter variables in registers; telling it which ones to use for 'top' and 'pc' makes a big difference and seems to ease pressure enough for it to deal with other variables as well. We do it for AMD64 and ARM64. Clang doesn't seem to need these directives. It does result in -Wclobbered warnings that seem difficult to silence. * src/bytecode.c (BC_REG_TOP, BC_REG_PC): New. (exec_byte_code): Use them.
* ; exec_byte_code: don't re-use op in FETCH2Mattias Engdegård2025-10-161-1/+1

* exec_byte_code: reduce use of semi-global 'op' (bug#79610)Mattias Engdegård2025-10-161-56/+65
| | | | | | | | | | | * src/bytecode.c (exec_byte_code): Re-type op from int to ptrdiff_t, which avoids some useless conversions. Reduce its use by using local variables for intra-block use, and another variable (arg) where it doesn't need to be alive across instruction dispatch. We also eliminate it where performance doesn't matter by re-fetching it from the instruction stream. All this should help the register allocator.
* ; elisp-scope.el: Standardize copyright notice.Eshel Yaron2025-10-161-4/+6
| | | | Suggested by Arash Esbati <arash@gnu.org>.
* Return case common to all completions in try-completionSpencer Baugh2025-10-163-8/+38
| | | | | | | | | | | | | | | When completion-ignore-case is non-nil, if all completions share a common prefix ignoring case, try-completion has always returned that. Now, if all completions also share a common prefix including case, try-completion includes that common prefix in its return value (bug#79377). * lisp/minibuffer.el (completion-pcm--merge-completions): Always use return value from try-completion, which may change case. * src/minibuf.c (Ftry_completion): Return the common prefix which changes case. * test/lisp/minibuffer-tests.el (completion-pcm-bug4219) (completion-substring-test-5): New tests.
* Improve color contrast of refine-related diff faces on dark backgroundsJuri Linkov2025-10-163-6/+6
| | | | | | | * lisp/vc/diff-mode.el (diff-refine-removed, diff-refine-added): * lisp/vc/ediff-init.el (ediff-fine-diff-A, ediff-fine-diff-B): * lisp/vc/smerge-mode.el (smerge-refined-removed, smerge-refined-added): Lower the dominant component of RGB colors from "aa" to "88" (bug#79633).

| | | | | * lisp/vc/vc-hooks.el (vc-after-revert): New function. (after-revert-hook): Add it.
* vc-auto-revert-mode: Fix an autoload problemSean Whitton2025-10-161-1/+4
| | | | | * lisp/vc/vc-hooks.el (auto-revert-mode): Replace compiler declaration for this variable with a full defvar-local.
* autorevert: Use defvar-local for the -mode variablesSean Whitton2025-10-161-2/+6
| | | | | | * lisp/autorevert.el (auto-revert-mode, auto-revert-tail-mode): Use defvar-local not defvar. New comment explaining why these duplicate definitions of the variables are present.
* ; * lisp/minibuffer.el (minibuffer--nonselected-check): Fix typos.Martin Rudalics2025-10-161-2/+2

* In 'minibuffer--nonselected-check' consult 'completion-reference-buffer'Martin Rudalics2025-10-161-4/+11

Calling 'treesit-available-p' in loaddefs.el is too early since the tree-sitter library might not be loaded yet. Checking if 'treesit-major-mode-remap-alist' is bound is equivalent to checking if Emacs is compiled with tree-sitter support. (bug#79622)
* time-stamp: padding with mixed uni- and multibyteStephen Gildea2025-10-151-10/+15
| | | | | | * lisp/time-stamp.el (time-stamp-string-preprocess): Use 'length' instead of 'format' to calculate string padding, so that we consistently count characters, not bytes.

| | | | | | * lisp/files.el (remote-shell-program): Don't bother looking for the full file name of the `ssh` executable, since all users end up looking it up in `load-path` anyway.

| | | | | | (completion--lazy-insert-strings-on-scroll): Don't move to the last completion candidate since this is what happens when scrolling without truncated completions buffer (bug#79506).

* (xdg-mime-apps): Restore corner case and simplifyStefan Monnier2025-10-151-17/+16
| | | | | | | * lisp/xdg.el (xdg-mime-apps): Return nil if that's what the table holds, like we did before commit f60fc1287d49. Consolidate the three (assoc type xdg-mime-table) and shrink the scope of `files`.

* (rx): Remove the `rx--pcase-expand` middle manStefan Monnier2025-10-141-7/+1
| | | | | * lisp/emacs-lisp/rx.el (rx): Remove the `rx--pcase-expand` middle man, now that `loaddefs-gen.el` expands the `pcase-defmacro` for us.
* (define-minor-mode): Update `global-minor-modes` if init-value is non-nilStefan Monnier2025-10-143-33/+28
| | | | | | | | | | | | | | | | When a global minor mode is enabled by init-value rather than by calling the major mode function, we failed to register it in `global-minor-modes` (bug#79518). * lisp/emacs-lisp/easy-mmode.el (define-minor-mode): Register ourselves in `global-minor-modes` at top-level for global modes with a non-nil init-value. Also in the `modefun`, simply the code with `not` and `add-to-list` and consolidate the local/global paths to update `*-minor-modes`. * lisp/simple.el (global-minor-modes): Move to... * lisp/subr.el (global-minor-modes): ...here so it's defined early enough for `auto-compression-mode` to register itself.
* Fix Tramp customizationMichael Albinus2025-10-142-2/+1
| | | | | | | | | | | Do not use the ;;;###tramp-autoload cookie for defcustoms. This damages the customisation when Tramp is autoloaded. Reported by Joel Reicher <joel.reicher@gmail.com>. * lisp/net/tramp-cache.el (tramp-verbose): Declare. (tramp-connection-properties): * lisp/net/tramp-message.el (tramp-verbose): Remove ;;;###tramp-autoload cookie.
