* lisp/progmodes/cc-engine.el (c-beginning-of-statement-1): Enhance the
analysis of case labels to handle parenthesised expressions (e.g. macros).
* lisp/progmodes/cc-langs.el (c-nonlabel-nonparen-token-key): New lang const
and lang var.
This is mainly by enhancing a parse-partial-sexp cache to retain recently
calculated values. Also, there are several miscellaneous optimizations and
bug fixes.
* lisp/progmodes/cc-engine.el (c-state-semi-nonlit-near-cache): New buffer
local variable.
(c-state-semi-trim-near-cache, c-state-semi-get-near-cache-entry)
(c-state-semi-put-near-cache-entry, c-state-semi-trim-cache): New functions.
(c-state-semi-pp-to-literal, c-state-full-pp-to-literal): Use the new "near"
cache.
(c-parse-ps-state-below): Use the new function c-state-semi-trim-cache.
(c-before-change-check-<>-operators): Check simply for < or > in the
neighbourhood before doing more expensive processing.
(c-maybe-re-mark-raw-string): Give a backward search limit to an operation
which was needlessly lacking one.
* lisp/progmodes/cc-mode.el (c-doc-fl-decl-start, c-doc-fl-decl-end): Check a
certain regexp is valid before performing the (somewhat expensive) actions of
these functions.
(c-fl-decl-start): In the search for a C++ lambda capture list, replace (slow)
calculation of c-parse-state by a (less slow) c-go-up-list-backward.
* lisp/progmodes/cc-engine.el (c-beginning-of-statement-1): The variable
before-sws-pos should record the position of a closing paren/brace/bracket
before moving backwards over a sexp. When there is a syntactic WS macro
between the starting point and the closing p/b/b, setq before-sws-pos again
after moving backward over the macro.
* lisp/progmodes/cc-engine.el (c-find-decl-prefix-search): Handle the new
matching possibility (of a #define construct) in the new
c-decl-prefix-or-start-re.
(c-find-decl-spots): Allow the initial search for an in-macro starting point
settle on the # of #define, to facilitate the regexp matching in
c-find-decl-prefix-search.
* lisp/progmodes/cc-langs.el (c-anchored-hash-define-no-parens): New lang
const.
(c-literal-start-regexp): Correct what was always supposed to be a "generic
string" regexp element.
(c-decl-prefix-or-start-re): Enhance also to match "#define <identifier>".
(c-dposr-cpp-macro-depth): New lang variable and lang constant.
In particulr, handle multiline block comments whose newlines are not escaped.
There is an example of this in #define EXTRA_CONTEXT_FIELDS in editfns.c.
* lisp/progmodes/cc-engine.el (c-beginning-of-macro, c-end-of-macro): Enclose
the loops scanning escaped newlines with outer loops which check
heuristically for, respectively, a block comment ender and a block comment
starter on the lines we end up on. (A rigorous syntactic check would be too
slow, here.)
* lisp/progmodes/cc-langs.el (c-last-c-comment-end-on-line-re)
(c-last-open-c-comment-start-on-line-re): New language constants/variables.
(c-restricted-<>-arglists, c-parse-and-markup-<>-arglists):
Move declaration before first use.
(c-after-change-unmark-raw-strings): Remove unused var `found-end`.
* lisp/progmodes/cc-engine.el (c-update-brace-stack): bind
c-parse-and-markup-<>-arglists and c-restricted-<>-arglists to t around the
call to c-forward-<>-arglist, to force the marking of template delimiters with
syntax-table text properties.
E.g., on typing the closing delimiter of a string continued onto a second
line, the opening delimiter retained its font-lock-warning-face.
* lisp/progmodes/cc-defs.el (c-c++-raw-string-opener-re)
(c-c++-raw-string-opener-1-re): New constants.
(c-sub-at-c++-raw-string-opener, c-at-c++-raw-string-opener): New macros.
* lisp/progmodes/cc-engine.el (c-raw-string-pos)
(c-depropertize-raw-strings-in-region, c-after-change-unmark-raw-strings):
Replace uses of open-coded raw string regexps by the new constants and macros
in cc-defs.el.
* lisp/progmodes/cc-fonts.el (c-font-lock-raw-strings): Ditto
* lisp/progmodes/cc-mode.el (c-before-change-check-unbalanced-strings): Set
c-new-BEG to the beginning of the string when we encounter its closing ".
When not in a raw string, but in a string, clear syntax-table properties from
its delimiters and set c-new-BEG/END to its limits.
(c-after-change-mark-abnormal-strings): When applying syntax-table properties
to string delimiters, also set c-new-BEG/END to ensure subsequent
fontification.
These are where changing the identifier in a raw string delimiter causes
different delimiters to match eachother.
* lisp/progmodes/cc-engine.el (c-raw-string-end-delim-disrupted): New
variable.
(c-before-change-check-raw-strings): Use new variable.
(c-after-change-unmark-raw-strings): When typing into an opening delimiter or
altering its close delimiter causes the opening delimiter to match a later
closing delimiter, clear all syntax-table char properties from the opening
delimiter onwards, and set c-new-END to point max. Also, when changing a
closing delimiter, check whether its new value matches a previously open
opening delimiter earlier in the buffer, and amend the syntax-table text
properties appropriately.
* lisp/progmodes/cc-engine.el (c-forward-sws, c-backward-sws): Recognize
matches of c-doc-line-join-re as syntactic whitespace.
(c-find-decl-prefix-search): Recognize and move over matches of
c-doc-line-join-re as whitespace.
(c-find-decl-spots): Before moving backward a char, check (bobp). Before
moving forward over a comment, check it isn't possibly a "bright" comment.
* lisp/progmodes/cc-fonts.el (c-get-doc-comment-style): New function,
extracted from c-compose-keywords-list.
(c-compose-keywords-list): Call the above new function.
(pike-font-lock-keywords, pike-font-lock-keywords-2)
(pike-font-lock-keywords-3): Call c-set-doc-comment-res.
(c-doc-line-join-re, c-doc-bright-comment-start-re, c-doc-line-join-end-ch):
New variables.
(c-set-doc-comment-re-element, c-set-doc-comment-char-list): New macros.
(c-set-doc-comment-res): New function.
(c-font-lock-doc-comments): For consistency and repeatability, in a sequence
of C++ style doc comments, don't fontify the region between BOL and the
comment marker.
(autodoc-line-join-re, autodoc-bright-comment-start-re)
(autodoc-line-join-end-ch): New variables.
* lisp/progmodes/cc-mode.el (c-doc-fl-decl-start, c-doc-fl-decl-end): New
functions.
(c-change-expand-fl-region, c-context-expand-fl-region): Call the above two
new functions for extra possibilities for the start and end of a construct.
* doc/misc/cc-mode.texi (Doc Comments): Add a sentence drawing attention to
the possibility of fontifying constructs within a doc comment.
* lisp/progmodes/cc-langs.el (c-class-id-suffix-ws-ids-kwds)
(c-class-id-suffix-ws-ids-key): New lang const/var.
* lisp/progmodes/cc-engine.el (c-guess-basic-syntax CASE 5D.4): Check for and
skip over any matches for c-class-id-suffix-ws-ids-key (i.e. "final") before
":".
Also firm up detection of beginning of brace list in
c-looking-at-or-maybe-in-bracelist.
* lisp/progmodes/cc-engine.el (c-looking-at-or-maybe-in-bracelist): On
detection of such a ref-qualifier, set braceassignp to nil. When this
variable has a nil value, return nil as the value of the function. On
encountering a } when scanning backwards, recognise this as the end of a
previous construct and stop the scan.
Integrate the handling of raw string and ordinary string fontification.
* lisp/progmodes/cc-defs.el (c-font-lock-flush)
(c-search-forward-char-property-without-value-on-char): new macros.
(c-point): In the 'eoll arm, check for eobp.
(c-search-forward-char-property-with-value-on-char): Handle the &optional
limit argument being nil.
(c-clear-char-property-with-value-on-char-function)
(c-clear-char-property-with-value-on-char): Return the position of the first
cleared property.
* lisp/progmodes/cc-engine.el (c-find-decl-prefix-search): Don't spuriously
recognize the change of face at a ) as the start of a string (a
"pseudo match").

other functions.
(c-propertize-raw-string-opener): Largely rewritten.

(c-after-change-unmark-raw-strings, c-after-change-unmark-raw-strings): New
functions.
* lisp/progmodes/cc-fonts.el (c-font-lock-raw-strings): Largely rewritten.
* lisp/progmodes/cc-langs.el (c-before-font-lock-functions): Replace
c-after-change-re-mark-unbalanced-strings by
c-after-change-mark-abnormal-strings in the t, c+objc, c++ and java sections.
Add c-after-change-unmark-raw-strings and remove
c-after-change-re-mark-raw-strings from the c++ section.

this function by a call to the new c-forward-class-decl.
* lisp/progmodes/cc-langs.el (c-type-decl-prefix-key): Recognize "~" as a
type decl operator.

c-lineup-2nd-brace-entry-in-arglist, c-lineup-class-decl-init-+, and
c-lineup-class-decl-init-after-brace.

beginning with the symbol first, followed by two of the new alignment
functions, followed by +.
* lisp/progmodes/cc-vars.el (c-offset-alist): Change the default value of
brace-list-entry from c-lineup-under-anchor back to 0.
Fix handling of CC Mode's syntactic WS cache. Make noise-macro option
variables buffer local.
* lisp/progmodes/cc-engine.el (c-put-is-sws, c-put-in-sws, c-remove-is-sws)
(c-remove-in-sws c-remove-is-and-in-sws): Add edebug specs.
(c-invalidate-sws-region-before): Add a `beg' parameter. Handle noise
macros like other literals.
(c-invalidate-sws-region-after-del): Move the adjustment of (cdr
c-sws-lit-limits) due to buffer change to c-invalidate-sws-region-after.
(c-invalidate-sws-region-after-ins): Move (goto-char end) to the correct
place.
(c-invalidate-sws-region-after): Adjust (cdr c-sws-lit-limits) due to buffer

parentheses.
* lisp/promodes/cc-mode.el (c-before-change): Supply a `beg' argument to

This fixes a bug reported by Yasushi SHOJI <yasushi.shoji@gmail.com> to
emacs-devel on 2018-11-26, where wrong analysis and fontification occurred.
* lisp/progmodes/cc-engine.el (c-beginning-of-statement-1): Add new parameter
HIT-LIM which, if non-nil causes the function to return nil rather than 'same
when we reach the backward search limit without finding the beginning of
statement.
(c-just-after-func-arglist-p): Supply argument t to this new parameter in call
to c-beginning-of-statement-1.
* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): When testing for an
identifier after "a *", on failure additionally check for a digit, setting a
new flag variable got-number if one is found. In the test for CASE 18, check
this flag.
This fixes bug #32808.
* lisp/progmodes/cc-engine.el (c-beginning-of-statement-1): New variable
comma-delimited, set when we're about to scan backward over a comma. Do not
reckon a brace block as bounding a statement when it is followed or preceded
by a comma (except when argument comma-delim is non-nil).
(c-guess-basic-syntax, CASE 9C): Call c-beginning-of-statement-1 with argument
comma-delim changed to non-nil.
* lisp/progmodes/cc-cmds.el, lisp/progmodes/cc-defs.el
lisp/progmodes/cc-engine.el, lisp/progmodes/cc-fonts.el
lisp/progmodes/cc-langs.el: Add lots of edebug specs.
* lisp/progmodes/cc-engine.el (c-state-maybe-marker): Tidy up so as to
evaluate an argument only once at runtime.
* lisp/progmodes/cc-engine.el (c-forward-over-token): New function, extracted
from ...
(c-forward-over-token-and-ws): Refactor to use the above.
(c-forward-type): Use c-check-qualified-type in place of c-check-type
(twice).
(c-forward-over-compound-identifier): New function.
(c-check-qualified-type): New function.
This happened when the type of the previous function was a struct, etc.,
declaration.
* lisp/progmodes/cc-mode (c-guess-basic-syntax CASE 5N): Check here (for
'topmost-intro-cont) that the first opening brace after BOD is the opening
brace preceding the starting point.
* lisp/progmodes/cc-engine.el (c-guess-basic-syntax; CASE 9B, CASE 9C): Set a
limit for a backward search to the ":" introducing the member init list, when
there is one, rather than the enclosing "{" or nil.

definition.
* lisp/progmodes/cc-langs.el (c++-make-template-syntax-table)
(c++-template-syntax-table): Remove.
(c-equals-type-clause-kwds, c-equals-type-clause-key): New language
constants/variables.
* lisp/progmodes/cc-engine.el (c-beginning-of-statement-1): At the end, accept
"." as a unary operator (which it now is in brace lists in, e.g., C Mode).
(c-guess-basic-syntax): Just before CASE 9C, move back to the previous brace
list entry in the block, rather than to the first one.
* lisp/progmodes/cc-engine.el (c-ssb-lit-begin): Remove.
(c-syntactic-skip-backward): Remove the surrounding c-self-bind-state-cache.
Use the standard function c-literal-start in place of the special purpose
c-ssb-lit-begin. With a suitable skip-chars argument (the usual case),
optimize by invoking c-backward-syntactic-ws to move back over comment blocks.
(c-determine-limit-get-base): Inovke an early c-backward-syntactic-ws.
(c-determine-limit): Use c-forward-comment whilst moving forward. Cope with
an empty position stack whilst looking for non-literals (bug fix). In the
recursive call, double try-size to prevent Lisp stack overflow.
* lisp/progmodes/cc-engine.el (c-after-conditional): Test for matches to
c-block-stmt-hangon-key.
* lisp/progmodes/cc-langs.el (c-block-stmt-hangon-kwds): New lang const.
(c-block-stmt-hangon-key): New lang const/var matching any element of the
above.
The regexp "\\<\\>", which is supposed never to match, actually matches, for
instance, where a Chinese character is directly followed by an ASCII letter.
So, replace it with "a\\`".

* lisp/progmodes/cc-engine.el (c-inside-bracelist-p): Return a bufpos rather
than t for the enum case.
(c-add-stmt-syntax, c-guess-continued-construct): Replace
c-looking-at-or-maybe-in-bracelist by c-inside-bracelist-p, since the former
does not recognize enum brace lists, but the latter does.
* lisp/progmodes/cc-fonts.el (c-get-fontification-context): Replace
c-looking-at-or-maybe-in-bracelist by c-inside-bracelist-p.
Also fix some errors with c-display-defun-name when there are nested classes.
* lisp/progmodes/cc-cmds.el (c-in-function-trailer-p): Deal with a struct {..}
being merely the type of a function.
(c-where-wrt-brace-construct): Deal with a struct {..} being merely the type
of a function. Rearrange the order of some Lisp forms. Insert a check for
c-protection-key ("private", etc.) alongside the checking for a label.
(c-defun-name-1): New function extracted form c-defun-name, which works within
the existing restriction. Don't regard 'at-function-end as being within the
defun any more. Recognize "struct", etc., with the new
c-defun-type-name-decl-key rather than c-type-prefix-key. Make the
recognition of a normal function more accurate.
(c-defun-name): Part left after extracting the above function. It now just
widens and calls c-defun-name-1.
(c-declaration-limits-1): New function extracted from c-declaration-limits,
which works within the existing restriction. Move LIM back one block to
account for the possibility of struct {..} as a function type. Check we're
not inside a declaration without braces.
(c-declaration-limits): Part left after extracting the above function. It now
just narrows to an enclosing decl block and calls c-declaration-limits-1.
(c-defun-name-and-limits): New function which identifies the name and limits
of the most nested enclosing declaration or macro.
(c-display-defun-name): Use c-defun-name-and-limits rather than two separate
functions (which didn't always agree on which function).
* lisp/progmodes/cc-engine.el (c-beginning-of-statement-1): If we have struct
{..} as the type of a function, go back over this, too.
* lisp/progmodes/cc-langs.el (c-defun-type-name-decl-kwds)
(c-defun-type-name-decl-key): New lang const/var.
* lisp/progmodes/cc-engine.el (c-looking-at-or-maybe-in-bracelist): Recognize
a brace list when preceded by "return" or inside parentheses, either
immediately after the "(" or following a comma.
(c-looking-at-inexpr-block): Test c-has-compound-literals rather than hard
coded C++ Mode.
(c-guess-basic-syntax, CASE 7B): Test additionally for not being just inside a
parenthesis or being at a Java "new" keyword. CASE 9: Remove the simple
minded test on the contents of a block to determine a brace list.
* lisp/progmodes/cc-langs.el (c-has-compound-literals): New lang const and lang var.
Don't merge to master; this is a quick fix for the emacs-26 branch. This is
essentially a reversion of the patch from 2017-11-10 which attempted to handle
C99's compound literals.
The bug here was triggered when a defun block contained a declaration ending
in a comma, yet without a semicolon.
* lisp/progmodes/cc-engine.el (c-guess-basic-syntax): At the CASE 9 test,
remove from the `or' form the test of a block's contents.
E.g.: someStruct x ( (nullptr != y) ? 3 : 4 )
Also fontify declarations of function pointers correctly.
* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): While testing for a
typeless declaration, additionally test the variable `got-prefix' to
recognize a function pointer in parentheses. Allow c-fdoc-shift-type-backward
to be invoked when we have nested parens.
Do this by removing a broken optimization in the state cache which put
category text properties on a character between the end of the CPP construct
and the beginning of the comment. This can't work when there's no such
