* src/data.c (circular_list): New function.
* src/lisp.h (FOR_EACH_TAIL): Use Brent’s algorithm and C99 for-loop
decl, to eliminate the need for the args TAIL, TORTOISE and N, and
to speed things up a bit on typical hosts with optimization.
All uses changed (Bug#25605).
* doc/lispref/nonascii.texi (Text Representations): Clarify that
'exact' value of QUALITY argument to 'bufferpos-to-filepos' and
'filepos-to-bufferpos' can lead to expensive and slow processing.
* lisp/international/mule-util.el (filepos-to-bufferpos)
(bufferpos-to-filepos): Doc fix. (Bug#25626)
* lisp/emacs-lisp/bytecomp.el (byte-compile-cond-vars): Use
(macroexp-cons-p) instead of (byte-compile-cond-valid-obj2-p) to
make sure that obj1/obj2 can be compared with `eq'.
* lisp/emacs-lisp/bytecomp.el (byte-compile-inline-lapcode):
Restore value of byte-compile-depth after emitting a jump to a tag
in a jump table, or default/done tags.
Set the depth of final tags for byte-switch to nil after emitting
any jumps to them.
* lisp/emacs-lisp/byte-opt.el (byte-decompile-bytecode-1):
Don't make a copy of the constant vector, as it isn't used with
the decompiled lapcode.
Make sure that the correct lapcode pair/list is being modified while
replacing the jump table.
* lisp/emacs-lisp/bytecomp.el (byte-compile-cond-valid-obj2-p) return
nil when OBJ is a non-keyword symbol (i.e a variable), as the jump
table can only be used when comparing variables with constant values.
* lisp/textmodes/css-mode.el (css-smie-grammar): Give colons belonging
to properties higher precedence.
(css--colon-inside-selector-p, css--colon-inside-funcall): New
functions for helping SMIE during tokenization.
(css-smie--forward-token, css-smie--backward-token): Distinguish
colons belonging to properties from other colons.
* test/manual/indent/css-mode.css: Add tests for the changes above.
* test/manual/indent/scss-mode.scss: Ditto.
* lisp/emacs-lisp/edebug.el (edebug-max-depth): Add defcustom.
(Bug#24713)
* etc/NEWS: Mention edebug-max-depth.
* doc/lispref/edebug.texi (Checking Whether to Stop): Mention
edebug-max-depth and index it. Add cross-references for
max-lisp-eval-depth and max-specpdl-size.
Co-authored-by: Eli Zaretskii <eliz@gnu.org>
* lisp/dired.el (dired-listing-switches): Document how to quote
options with embedded whitespace.
* lisp/files.el (insert-directory): Use split-string-and-unquote
to support dired-listing-switches that specify command-line
options with embedded spaces. (Bug#25485)
Make the existing if-let and when-let aliases.
* lisp/emacs-lisp/subr-x.el (if-let*, when-let*): New macros. Rewrite
docstrings, incorporating that from let* and the existing if-let.
(if-let, when-let, and-let*): Alias them.
alloc.c had bitrotted a bit, and used an undefined symbol
stack_base when Emacs was built on Solaris sparc, leading to
compilation failures. Also, code related to __builtin_unwind_init
was unnecessarily duplicated. Fix the bitrot and remove some
duplication.
* src/alloc.c: Remove uses of GC_SAVE_REGISTERS_ON_STACK, since it
is never defined.
(test_setjmp) [!HAVE___BUILTIN_UNWIND_INIT && GC_SETJMP_WORKS]:
Define a no-op dummy, to simplify use.
(test_setjmp) [!GC_SETJMP_WORKS]: Test setjmp_tested_p here rather
than in the caller, to simplify use.
(stacktop_sentry): New type.
(__builtin_unwind_init) [!HAVE___BUILTIN_UNWIND_INIT]: New macro.
(SET_STACK_TOP_ADDRESS): New macro, containing code that was duplicated.
(flush_stack_call_func, Fgarbage_collect): Use it.
(init_alloc): Omit unnecessary initialization.
After dumping, Emacs need not re-test setjmp.
* src/xdisp.c (partial_line_height): New function.
(try_scrolling):
* src/window.c (window_scroll_pixel_based): Use it for calculating the
pixel scroll margin correctly in a window with partial lines.
* src/xdisp.c (maximum-scroll-margin): New variable.
* lisp/cus-start.el: Make it customizable.
* etc/NEWS: Mention it.
* doc/emacs/display.texi (Auto Scrolling):
* doc/lispref/windows.texi (Textual Scrolling): Document it.
* src/window.c (window_scroll_pixel_based): Use it instead of hardcoding
division by 4 (Bug #5718).
Its effective range needs to be clamped between 0 and (window height /
4), so it's better to have this constraint in a single place.
* src/window.c (window_scroll_margin): New function.
(window_scroll_pixel_based, window_scroll_line_based):
(Frecenter, Fmove_to_window_line):
* src/xdisp.c (try_scrolling, try_cursor_movement):
(redisplay_window, try_window, try_window_id): Use it.
* src/lisp.h (STACK_CONS, AUTO_STRING_WITH_LEN):
Parenthesize compound literals that are function call args.
Although this does not fix any bugs, it is the proper style for
macro parenthesization as it means this code will continue to
work even if make_lisp_ptr is changed to a macro.
