2025-01-19Replace call[1-8] with callnStefan Kangas
Since the introduction of the 'calln' macro, the 'call1', 'call2', ..., 'call8' macros are just aliases for the former. This is slightly misleading and potentially unhelpful. The number of arguments N can also easily go out-of-synch with the used alias callN. There is no reason not to replace these aliases with using 'calln' directly. To reduce the risk for mistakes, the tool Coccinelle was used to make these changes. See <https://coccinelle.gitlabpages.inria.fr/website/>. * src/alloc.c, src/androidvfs.c, src/androidfns.c, src/buffer.c: * src/callint.c, src/callproc.c, src/casefiddle.c, src/charset.c: * src/chartab.c, src/cmds.c, src/coding.c, src/composite.c: * src/data.c, src/dbusbind.c, src/dired.c, src/doc.c: * src/emacs.c, src/eval.c, src/fileio.c, src/filelock.c: * src/fns.c, src/frame.c, src/gtkutil.c, src/haikufns.c: * src/haikumenu.c, src/image.c, src/insdel.c, src/intervals.c: * src/keyboard.c, src/keymap.c, src/lisp.h, src/lread.c: * src/minibuf.c, src/nsfns.m, src/nsselect.m, src/pgtkfns.c: * src/pgtkselect.c, src/print.c, src/process.c, src/sort.c: * src/syntax.c, src/textconv.c, src/textprop.c, src/undo.c: * src/w32fns.c, src/window.c, src/xfaces.c, src/xfns.c: * src/xmenu.c, src/xselect.c, src/xterm.c: Replace all uses of 'call1', 'call2', ..., 'call8' with 'calln'.

2024-08-22Prefer static_assert to verifyStefan Kangas
Although static_assert is C11-specific, and Emacs remains on C99, it has been backported to older compilers by Gnulib. Gnulib has already changed to prefer static_assert, and we can do the same. * lib-src/asset-directory-tool.c (main_2): * src/alloc.c (BLOCK_ALIGN, aligned_alloc, lisp_align_malloc) (vectorlike_nbytes, allocate_pseudovector): * src/android.c (android_globalize_reference, android_set_dashes): * src/android.h: * src/androidfont.c (androidfont_draw, androidfont_text_extents): * src/androidvfs.c: * src/bidi.c (BIDI_CACHE_MAX_ELTS_PER_SLOT, bidi_find_bracket_pairs): * src/buffer.c (init_buffer_once): * src/casefiddle.c (do_casify_multibyte_string): * src/dispnew.c (scrolling_window, scrolling): * src/editfns.c (styled_format): * src/emacs-module.c (module_extract_big_integer): * src/fileio.c (Fdo_auto_save): * src/fns.c (next_almost_prime, hash_string): * src/fringe.c (init_fringe): * src/keyboard.h (kbd_buffer_store_event_hold): * src/keymap.c: * src/lisp.h (memclear, reduce_emacs_uint_to_hash_hash, modiff_incr): * src/lread.c (skip_lazy_string): * src/pdumper.c (dump_bignum, Fdump_emacs_portable) (dump_do_dump_relocation, pdumper_load): * src/process.c (make_process, Fmake_process, connect_network_socket): * src/regex-emacs.c: * src/sort.c (tim_sort): * src/sysdep.c (init_random, SSIZE_MAX): * src/thread.c: * src/timefns.c (trillion_factor): * src/unexelf.c: * src/xterm.c (x_send_scroll_bar_event): Prefer static_assert to Gnulib verify. Remove import of verify.h, except when used for other reasons.
2024-06-04Spelling fixesPaul Eggert
2024-05-11; More coding style fixesPo Lu
* src/sort.c (reverse_sortslice, tim_sort): Correct not-so egregious misformattings.
2024-05-11; Fix coding style in timsort.cPo Lu
* src/sort.c (reverse_slice, sortslice): Fix egregious coding style inconsistencies.
2024-04-30Pacify GCC 14 -Wnull-dereference in tim_sortPaul Eggert
* src/lisp.h (tim_sort): Require array arg to be nonnull. * src/sort.c (reverse_slice): Omit no-longer-needed eassert. (tim_sort): Avoid undefined behavior when length == 0, since reverse_slice would then compute &seq[-1].
2024-04-14GC-mark temporary key values created when sorting (bug#69709)Mattias Engdegård
Bug reported and fix proposed by Aris Spathis. * src/sort.c (merge_markmem): Mark heap-allocated temporary key values. (tim_sort): Delay key function calls to after marking function has been registered. * test/src/fns-tests.el (fns-tests-sort-gc): New test.
2024-03-29Speed up `sort` by special-casing the `value<` orderingMattias Engdegård
This gives a 1.5x-2x speed-up when using the default :lessp value, by eliminating the Ffuncall overhead. * src/sort.c (order_pred_lisp, order_pred_valuelt): New. (merge_state, inorder, binarysort, count_run, gallop_left, gallop_right) (merge_init, merge_lo, merge_hi, tim_sort): * src/fns.c (Fsort): When using value<, call it directly.
2024-03-29New `sort` keyword arguments (bug#69709)Mattias Engdegård
Add the :key, :lessp, :reverse and :in-place keyword arguments. The old calling style remains available and is unchanged. * src/fns.c (sort_list, sort_vector, Fsort): * src/sort.c (tim_sort): Add keyword arguments with associated new features. All callers of Fsort adapted. * test/src/fns-tests.el (fns-tests--shuffle-vector, fns-tests-sort-kw): New test. * doc/lispref/sequences.texi (Sequence Functions): Update manual. * etc/NEWS: Announce.
2024-03-29Add back timsort key function handling (bug#69709)Mattias Engdegård
The original timsort code did provide for a key (accessor) function along with the necessary storage management, but we dropped it because our `sort` function didn't need it. Now it's been put back since it seems that it will come in handy after all. * src/fns.c (sort_list, sort_vector, Fsort): Pass Qnil as key function to tim_sort. * src/sort.c (reverse_slice, sortslice_copy) (sortslice_copy_incr, sortslice_copy_decr, sortslice_memcpy) (sortslice_memmove, sortslice_advance): New functions. (sortslice): New type. (struct stretch, struct reloc, merge_state) (binarysort, merge_init, merge_markmem, cleanup_mem) (merge_register_cleanup, merge_getmem, merge_lo, merge_hi, merge_at) (found_new_run, reverse_sortslice, resolve_fun, tim_sort): Merge back previously discarded parts from the upstreams timsort code that dealt with key functions, and adapt them to fit in.
2024-01-09Use `min`/`max` macros in a few more placesStefan Kangas
* src/bidi.c (bidi_set_sos_type): * src/coding.c (consume_chars): * src/dosfns.c (dos_memory_info): * src/emacs.c (sort_args): * src/insdel.c (count_combining_before) (count_combining_after, replace_range, del_range_2): * src/sort.c (tim_sort): * src/w32.c (sys_write): * src/xfaces.c (face_at_buffer_position) (face_for_overlay_string): Prefer using 'min' and 'max' macros.
