- We should report bugs to the GitHub Issues
- We should advocate using Discourse instead of the superseded cfe-dev
mailing list.
There are a couple of other cosmetic changes such as preferring `using`
instead of `typedef` and quoting the `-analyze-function` parameter's
payload for escaping the braces.
Thanks @loic-joly-sonarsource for reporting this on Discord!

Implement P2128R6 in C++23 mode.
Unlike GCC's implementation, this doesn't try to recover when a user
meant to use a comma expression.
Because the syntax changes meaning in C++23, the patch is *NOT*
implemented as an extension. Instead, declaring an array with not
exactly 1 parameter is an error in older languages modes. There is an
off-by-default extension warning in C++23 mode.
Unlike the standard, we supports default arguments;
Ie, we assume, based on conversations in WG21, that the proposed
resolution to CWG2507 will be accepted.
We allow arrays OpenMP sections and C++23 multidimensional array to
coexist:
[a , b] multi dimensional array
[a : b] open mp section
[a, b: c] // error
The rest of the patch is relatively straight forward: we take care to
support an arbitrary number of arguments everywhere.
This completes the implementation of
WG14 N2412 (http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2412.pdf),
which standardizes C on a twos complement representation for integer
types. The only work that remained there was to define the correct
macros in the standard headers, which this patch does.
Although we moved to Github Issues. The bug report message refers to
Bugzilla still. This patch tries to update these URLs.

This implements p2085, allowing out-of-class defaulting of comparison
operators, primarily so they need not be inline, IIUC intent. this was
mostly straigh forward, but required reimplementing
Sema::CheckExplicitlyDefaultedComparison, as now there's a case where
we have no a priori clue as to what class a defaulted comparison may
be for. We have to inspect the parameter types to find out. Eg:
class X { ... };
bool operator==(X, X) = default;
Thus reimplemented the parameter type checking, and added 'is this a
friend' functionality for the above case.

This reverts commit 2d7fba5f95.
The patch was reverted because it caused regression with rocThrust
due to ambiguity of template specialization.
For details please see https://reviews.llvm.org/D109496
A resolution to the ambiguity issues created by P0522, which is a DR solving
CWG 150, did not come as expected, so we are just going to accept the change,
and watch how users digest it.
For now we deprecate the flag with a warning, and make it on by default.
We don't remove the flag completely in order to give users a chance to
work around any problems by disabling it.

This is the second part of p0388, dealing with overloads of list
initialization to incomplete array types. It extends the handling
added in D103088 to permit incomplete arrays. We have to record that
the conversion involved an incomplete array, and so (re-add) a bit flag
into the standard conversion sequence object. Comparing such
conversion sequences requires knowing (a) the number of array elements
initialized and (b) whether the initialization is of an incomplete array.
This also updates the web page to indicate p0388 is implemented (there
is no feature macro).

Distinct lambda expressions are always considered non-equivalent, so two
token-for-token identical function declarations whose signatures involve
lambda-expressions declare distinct functions.
Desccribe in cxx_status.html the missing parts of the partially

I noticed that these two DRs are currently working correctly, so I
added a pair of lit tests that check the AST (which is most useful for
CWG1779, since 'dependent' is really only observable in an ast dump) to
make sure __func__ works correctly in dependent cases, and in lambda
operator().
Also noticed that CWG1762, mostly an 'example' change, works correctly,
so added a test so that it gets marked 'done' as well.
Additionally, I regenerated cxx_dr_status.html, updating it for Clang
13's release, based on the cwg_status.html from August 12, 2021.

This doesn't add all of the document numbers, but it adds a bunch of
them. Not all of the documents are available on the committee page
(they're old enough that they come from a time when the mailing was
comprised of physical pieces of paper), so some of the documents listed
are assumed to be correct based on my reading of editor's reports.
This adds the Unicode 13 data for XID_Start and XID_Continue.
The definition of valid identifier is changed in all C++ modes
as P1949 (https://wg21.link/p1949) was accepted by WG21 as a defect
report.
This patch implements P2092
Simple requirements in requirement body shall not start with requires.
A warning was already in place so we just turn this warning into an error.
In addition, we add tests to make sure typename is optional in
requirement-parameter-list as per the same paper.
Support Narrowing conversions to bool in if constexpr condition
under C++23 language mode.
Only if constexpr is implemented as the behavior of static_assert
is already conforming. Still need to work on explicit(bool) to
complete support.
This adds implementation information for N2607,
clarifies that C17 only resolved defect reports,
and adds -std= information for the different versions.
This completes the series implementing p1099, by adding the feature
macro and updating the web page.
