dbac923b9d CC Mode: On removal of "typedef", remove pertinent types from c-found-types
For this purpose, record the type names declared by typedef in a text
property, c-typedef, on the typedef.  On any change to that "typedef" or a
type, remove the old identifier(s) from c-found-types.

This should fix bug #59671.

* lisp/progmodes/cc-defs.el (c-search-forward-non-nil-char-property): New
macro.

* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): Move the scope of
identifier-start from the "inner" let form to the outer one.  Amend the
return value such that the middle element of the second element is now the
position of the "typedef", not merely non-nil.

* lisp/progmodes/cc-fonts.el (c-font-lock-declarators): Disregard the LIMIT
parameter when fontifying the declarators of a typedef construct.  Also in
this case, set the c-typedef text property on the "typedef" to the list of
declared types.  Amend this list when these declared types change.
(c-font-lock-single-decl): Massage the `types' argument given to
c-font-lock-declarators.
(c-font-lock-cut-off-declarators): Amend to work when the starting point of
the fontification is inside a brace block.

* lisp/progmodes/cc-mode.el (c-before-change-de-typedef)
(c-after-change-de-typedef): New functions.
(c-update-new-id): Replace the erroneous c-end-of-current-token with a clause
containing c-forward-token-2.
(c-before-change): Call c-before-change-de-typedef.
(c-after-change): Call c-after-change-de-typedef.

1cbc22b9c7 CC Mode: partially revert commit from 2022-10-04
This reversion is of an ill-advised optimization, which resulted in non-type
identifiers getting fontified as types.

* lisp/progmodes/cc-fonts.el (c-fontify-new-found-type): Rather than writing
the expected face directly to the text, instead remove the `fontified'
property.  This allows the full font-lock mechanism to fontify the buffer
correctly.

This fixes bug #58772.

return (decl . nil) when MATCH-POS is in the second paren list of something
like DEFUN (..) (..).  Tidy up untidy code with save-excursion's for greater
accuracy.  Set a c-type text property value c-decl-arg-start to speed up

value `just-one' of c-promote-possible-types, and if found, fontify the type,
but don't add it to c-found-types.
(c-forward-decl-or-cast-1): Add the new &optional parameter inside-macro.
Whilst checking for a cast construct, analyze the text following the closing
paren more rigorously.
Check for, and allow, the closing paren of a macro arglist before the putative
cast construct.

* lisp/progmodes/cc-fonts.el (c-font-lock-declarations): In the lambda
function, pass the parameter inside-macro to c-forward-decl-or-cast-1.

* lisp/progmodes/cc-langs.el (c-primary-expr-regexp-details): New
c-lang-defvar which calculates `c-primary-expr-regexp' and three match
numbers for various sub-expressions in the regexp.
(c-primary-expr-regexp): Now extracted from `c-primary-expr-regexp-details'.
(c-per-++---match, c-per-&*+--match, c-per-\(-match): New

name as font-lock faces are bound before accessing their values.

fb8276a17c CC Mode: Cease adding types to found-types too eagerly
This fixes bug #58537 and bug #58539.

* lisp/progmodes/cc-engine.el (c-forward-type): Remove trailing whitespace
from an identifier before passing it to c-add-type.
(c-forward-decl-or-cast-1): CASE 3: Do not recognize two consecutive
identifiers as type + variable/function unless certain conditions are met.
CASE 10: Do not recognize the "type" as a found type unless certain condtions
are met.  (Near end): Do not recognize the identifier in a cast as a type
unless certain conditions are met.

* lisp/progmodes/cc-fonts.el (c-get-fontification-context): Recognize being
in declaration parens when there is a syntactially wrong "foo ((bar))"
preceding the match position.

* lisp/progmodes/cc-mode.el (c-update-new-id): Set c-new-id-is-type
unconditionally to nil to prevent a second identifier being wrongly marked as
a type.

Give both the "" and _tag font-lock-function-name-face.  Also correct the
fontification of an inherited class name when there is an attribute between
the class name being declared and the colon introducing the inheritance.

* lisp/progmodes/cc-engine.el (c-forward-over-colon-type-list): New function.
(c-forward-keyword-clause): Use the above new function instead of a
looking-at.
(c-forward-name, c-forward-declarator): Accept both the "" and the tag as part
of the name.

* lisp/progmodes/cc-fonts.el (c-font-lock-declarators): Fontify the "" (which
already has font-lock-string-face) and the tag with
font-lock-function-name-face.

* lisp/progmodes/cc-langs.el (c-overloadable-operators): Add "" to this list.

t to (&rest body), in line with the fix to bug #16184.

a18918df0b CC Mode: Refactor c-forward-delarator and callers
c-forward-declarator now moves over a complete declarator, including any
arglist expression, but possibly not including certain C++20 constructs.

* lisp/progmodes/cc-engine.el (c-forward-decl-arglist): New function,
extracted from c-do-declarators.
(c-forward-declarator): Extend the result list by one element, denoting
whether the function parsed an argument list.  Insert special handling for a
C++ operator<op> construct.  If there is a parenthesis expression, and it is
an argument list, move forward over it.
(c-do-declarators): Append an optional parameter, cdd-anon-accepted
instructing the function to handle declarators without identifiers.  Extract
c-forward-decl-arglist.

* lisp/progmodes/cc-fonts.el (c-font-lock-declarators): New &optional
parameter accept-anon, as above.  Analyze and use the identifier location
returned by c-do-declarators, rather than using c-last-identifier-range.
(c-font-lock-single-decl): Determine accept-anon from the context, passing it
as argument to c-font-lock-declarators.

* lisp/progmodes/cc-langs.el (c-opt-identifier-prefix-key): Make a
c-lang-defvar out of this existing c-lang-defconst.

* lisp/progmodes/cc-mode.el (c-fl-decl-end): Adapt for the new
c-forward-declarator which now moves over arglists.  Amend better to handle
certain syntactically invalid constructs in C++.

71b7ad0cf7 C++ Mode: Fontify functions correctly with commas in template expressions
This fixes bug #57318.

Also apply an optimization which marks generic expressions as already
analyzed, thus avoiding repeating this analysis when not needed.  This
optimization prevents the fix slowing down scrolling when the C++ source has
lots of template structures.

* lisp/progmodes/cc-engine.el (top-level) Near the beginning of the file, add
a comment describing the new text property c-<>-c-types-set.
(c-update-brace-stack): Bind c-restricted-<>-arglists to nil rather than t
around the call to c-forward-<>-arglist.
(c-forward-<>-arglist-recur): Allow the abbreviated analysis of a generic
expression also when the opening < is marked with a c-<>-c-types-set text
property.  Set this property at the same time as the c-type properties are set
on the commas inside the template structure.

* lisp/progmodes/cc-fonts.el (c-font-lock-complex-decl-prepare): Clear the
c-<>-c-types-set text property, along with c-type, from the region being
fontified.

c-after-suffixed-type-maybe-decl-key).

`c-not-decl' to the values of c-type which are erased at the start of a
fontification.

Partially revert the commits from 2021-10-24 - 2021-10-26, "CC Mode: Fontify
"found types" which are recognized after being first scanned".

This removes the background fontification which ran off of a 0.1s timer, but
leaves the facility of normal fontification causing the fontification
throughout the buffer of newly found types.

60a8583420 C++ Mode: Fix incoorect background fontification of <
Where c-record-found-types gets "bound" to itself, we postpone the calling of
c-fontify-new-type on possible new found types until these are confirmed by
the return from the function tentatively finding these types, for exmaple
c-forward-<>-arglist.  We check this "binding" by testing the value of
c-record-found-types.

Correct the background fontification algorithm.

* lisp/progmodes/cc-engine.el (c-record-found-types): Move the definition to
earlier in the file.
(c-add-type-1): Check additionally c-record-found-types is nil before calling
c-fontify-new-found-type.
(c-forward-<>-arglist, c-forward-type): On return from a function which
collects found types in c-record-found-types, call c-fontify-new-found-types
for each such type.

* lisp/progmodes/c-fonts.el (c-force-redisplay): Actually fontify the new
found type.
(c-fontify-new-found-type): Test for font-lock-mode being enabled.  Remove the
spurious condition on the `fontified' text property being nil before causing
c-force-redisplay to get called.
