certain parts by default. Now the MIME buttons in the article buffer
indicate how to fetch the complete message in order to act on those
missing parts.
* lisp/gnus/gnus-art.el (gnus-insert-mime-button): Indicate not
downloaded parts in MIME buttons.
* src/fns.c (Ffillarray, Fclear_string):
Add CHECK_IMPURE here, to be consistent with Faset etc.
(Ffillarray): Prefer memset when the fill is a single byte.

executable via purecopy, as this does not work with the pdumper.

(comp-call-optim-func): Reflect `comp-call-optim-form-call'
parameter removal.
Fixes bug #41284.
* lisp/progmodes/cc-langs.el (c-type-decl-prefix-key): include additionally
c-modifier-kwds in the set of keywords at the base of this lang-const.
* lisp/emacs-lisp/comp.el (comp-never-optimize-functions):
Blacklist all primitives advised by evil-mode from trampoline
optimization.
(comp-call-optim-form-call): Prevent trampoline optimization for
recursive calls at speed 2 to respect elisp original semantic.
It has been missing since 2012-07-03 (Emacs 24.3)
"Cleanup basic buffer management", when undo_list was moved to
the end of struct buffer. (Bug#33492)

__builtin_unwind_init.
(flush_stack_call_func1): Rename from 'flush_stack_call_func'.
(flush_stack_call_func): New function to spill all registers
before calling 'flush_stack_call_func1'. This to make sure the
top of the stack identified includes those registers.
* lisp/mouse.el (mouse-drag-and-drop-region-show-tooltip): Fix
defcustom type to allow all valid values. Suggested by David
Ponce. (Bug#41351)
(mouse-drag-and-drop-region): Fix bug where setting
`drag-and-drop-region-show-tooltip' to 0 would still show a
tooltip.
* src/comp.c (load_comp_unit): While loading from dump lambda
fixups are still to happen here. Verify relocation coherency only
after 'top_level_run' execution.
Inspired by patch proposed by Dmitry Gutov (Bug#40671#393)
and by further comments by him and by Michael Heerdegen
in the same bug report.

In a footnote, contrast the Emacs behavior with that of Common
Lisp, Python, etc. for clarity, and say the goal is to be nicer.
From a patch privately suggested by Mattias Engdegård on 2020-05-11
in a followup to Bug#40671.

Some themes (like dracula) make the region face inherit from some
other face. If the background color of the region was inherited,
`indicate-copied-region' did the switch-point-and-mark-twice dance
which is not visible in case the region is highlighted. It just
looked like Emacs would hang for a second after M-w.
* lisp/simple.el (indicate-copied-region): Consider face inheritance
when checking region face background.
* lisp/progmodes/cc-engine.el (c-end-of-macro): Fix faulty cache handling,
where the upper bound of c-macro-cache was never being set.

backward searching with lots of escaped newlines in c-backward-single-comment.
(c-backward-single-comment, c-backward-comments): Use the new macro above.
* lisp/progmodes/cc-mode.el (c-before-change-check-unbalanced-strings)
(c-after-change-mark-abnormal-strings, c-after-change-escape-NL-in-string):
Optimize three regexps by using shy groups, thus preventing regexp stack
overflow while handling the large C Macro.
* lisp/emacs-lisp/comp.el (comp-lex-byte-func-p): New subst.
(comp-intern-func-in-ctxt): Do not crash if we still encounter a
non lexical scoped lambda.
