* src/textprop.c (Fnext_single_char_property_change): Clarify in
the doc string the behavior when LIMIT is past the end of OBJECT.
Stop the search when position gets to end of buffer, for when LIMIT
is beyond that. (Bug#40000)
Problem reported by Andreas Schwab in:
https://lists.gnu.org/r/emacs-devel/2020-05/msg00650.html
* src/conf_post.h (HAS_ATTR_no_sanitize): Define to false in case
cpp is picky, fixing a longstanding glitch here.
(ATTRIBUTE_NO_SANITIZE_ADDRESS, ATTRIBUTE_NO_SANITIZE_UNDEFINED):
Use HAS_ATTRIBUTE, not __has_attribute.
attribute.h is partly designed for C2X forward compatibility,
since C2X will add some standard attributes. Using its macros
should help insulate Emacs from C2X teething problems.
* src/conf_post.h: Include attribute.h.
(HAS_ATTRIBUTE, HAS_FEATURE): Rename from __has_attribute and
__has_feature, to avoid polluting the builtin namespace.
All uses changed.
(ATTRIBUTE_COLD, ATTRIBUTE_FORMAT, FALLTHROUGH, ATTRIBUTE_CONST)
(ATTRIBUTE_PURE, ATTRIBUTE_UNUSED, ATTRIBUTE_MAY_ALIAS)
(ATTRIBUTE_MALLOC, ATTRIBUTE_ALLOC_SIZE)
(ATTRIBUTE_RETURNS_NONNULL): Remove, as attribute.h does this now.
(NO_INLINE, EXTERNALLY_VISIBLE, ARG_NONNULL, ATTRIBUTE_UNUSED):
Simplify by defining in terms of attribute.h macros.
* src/systhread.h (ATTRIBUTE_WARN_UNUSED_RESULT): Remove.
All uses replaced by attribute.h’s NODISCARD.

7a12ab5ea2 Fix project.el commands in "transient" projects
274ec97e3c Make sure alist-related functions say so in their doc
It is conceptually wrong for apropos commands that search doc
strings to look for matches of several words only on the same
line, because division of doc strings between lines is
ephemeral.
* lisp/apropos.el (apropos-parse-pattern): Accept an optional
argument MULTILINE-P, and if that is non-nil, produce regexps that
match words in the list even if they are separated by line
boundaries.
(apropos-value, apropos-local-value, apropos-documentation): Use
the new optional argument in apropos commands that search
multiline text, such as doc strings.
* src/search.c (Fposix_looking_at, Fposix_string_match)
(Fposix_search_backward, Fposix_search_forward): Make sure Posix
appears in the doc strings near REGEXP, for better matches.
* src/term.c (encode_terminal_code): Each character from an
automatic composition is a multibyte character, so its multibyte
representation can take up to MAX_MULTIBYTE_LENGTH bytes.
Account for that when allocating storage for characters to be
encoded. (Bug#40913)
* src/character.h (multibyte_length):
Merge tests so that there are fewer conditional branches.
This improved CPU speed of ‘make compile-always’
by about 1.5% on my platform.
* src/editfns.c (Fstring_to_char): Simplify.
* src/editfns.c (Fstring_to_char): Simplify.
This tweak improved the CPU time performance of
‘make compile-always’ by about 1.8% on my platform.
This tweak improved the CPU time performance of
‘make compile-always’ by about 1.7% on my platform.
* src/character.c (string_char): Remove; no longer used.
* src/character.h (string_char_and_length): Redo so that it
needn’t call string_char. This helps the caller, which can now
become a leaf function.
This reclaims a bit of performance when compiling with gcc -Og.
These functions were macros until I changed them in
2020-04-17T14:57:25Z!eggert@cs.ucla.edu.
* src/casefiddle.c (make_char_unibyte):
* src/ccl.c (GET_TRANSLATION_TABLE): Now inline.
* src/comp.c (native_function_doc): New function.

layout.
(syms_of_alloc): Likewise.

(comp-emit-for-top-level): Emit doc index as 'comp--register-subr'
doc parameter.

Without a call to image_find_image, we can get a file name that
is relative to data-directory/images/, or a file name that
starts with "~/", in which case w32_load_image would fail.
* src/image.c (native_image_load): Call image_find_image_file to
resolve and encode the image file name.
* src/w32image.c (w32_load_image): No need to encode the file
name, as it's already encoded by native_image_load.
* src/xdisp.c (get_next_display_element): For a composition on a
display or overlay string, set the end_of_box_run_p flag if the
string ends at the last character included in the composition.
(fill_gstring_glyph_string): Fix the way the width of a gstring
glyph string is calculated: use the values calculated in
gui_produce_glyphs, since the latter adjusts the width due to the
face's ':box' attribute.
* src/xterm.c (x_draw_glyph_string_box):
* src/w32term.c (w32_draw_glyph_string_box):
* src/nsterm.m (ns_dumpglyphs_box_or_relief): Support automatic
compositions, which have the right_box_line_p flag set on the last
glyph produced from the composition. (Bug#40687)
* src/w32term.c (w32_compute_glyph_string_overhangs): Update to be
consistent with xterm.c in its support of automatic composition
glyph strings.
* src/dispextern.h (enum glyph_type): More accurate commentary.
* src/.gdbinit (pgx): Display slice.img members only for image
glyphs.
* src/keymap.c (push_text_char_description): Omit useless code.
(Ftext_char_description): Minor code cleanup, inspired by
seeing an incorrect comment about MAX_MULTIBYTE_LENGTH’s value.
* src/character.c (parse_str_as_multibyte, str_as_multibyte):
Let the fast loop run a little longer, fixing what appears
to be an off-by-1 performance nit.
* src/character.h (MULTIBYTE_LENGTH, MULTIBYTE_LENGTH_NO_CHECK):
Remove, replacing with ...
(multibyte_length): ... this new function. All callers changed.
The new function rejects overlong multibyte forms.
* test/src/buffer-tests.el (buffer-multibyte-overlong-sequences):
New test.
* src/w32image.c (w32_load_image): Remove a workaround for a bug
that is not needed anymore. This error was happening because
GDI+ functions were called as CDECL, not as STDCALL.
* src/w32image.c: Define correct WINGDIPAPI typedefs for GDI+
functions. We cannot use DEF_DLL_FN, since that is for functions
with C calling conventions, whereas GDI+ functions are __stdcall.
(gdiplus_init): Load functions from DLL manually, not via
LOAD_DLL_FN, as the latter is for __cdecl functions.
(w32_frame_delay): Initialize delay with a negative value, as zero
is a valid delay.
This is a preventive change, since Gnulib was recently changed
its explicit_bzero to call SecureZeroMemory on MS-Windows,
disregarding systems older than XP, which didn't have it.
* src/w32.c (explicit_bzero): New function.
* nt/mingw-cfg.site (ac_cv_func_explicit_bzero): Avoid using the
Gnulib replacement for explicit_bzero.
* nt/inc/ms-w32.h (explicit_bzero): Add prototype.
