Hi Joseph,
I've fixed the documentation (compared to what I suggested on the list,
I've removed the obsolescence mention, and I've s/separated/terminated/
which I think is more accurate about the semicolon in lists of parameter
forward declarations).
I've also added extend.texi to the ChangeLog,

void f(int x; int x; int x);
Add a new diagnostic, -Wmultiple-parameter-fwd-decl-lists, which
diagnoses uses of this obsolescent syntax.
Add this diagnostic in -Wextra.

Both of the tests under 128 bit are raising:
warning: writing 16 bytes into a region of size 8 [-Wstringop-overflow=]
when compiling, leading to a test fail. The warning is caused by the
incorrect array size for res_ref2. The wrong size caused the overflow.

Hi,
This patch adds gather/scatter handling for grouped access. The idea is
to e.g. replace an access (for uint8_t elements) like
arr[0]
arr[1]
arr[2]

arr[1 + step]
...
by a gather load of uint32_t

Hi,
This patch removes the type argument from the vector_misalignment hook.
Ever since we switched from element to byte misalignment its
semantics haven't been particularly clear and nowadays it should be
redundant.

where the SUBREG wraps the result of the shift. This leaves the AND

Create a new method for checking and emitting errors on pragmas
Unused, Unrefefrenced, Unreferenced_Objects, Inline and No_Return
that support specifying multiple entities as arguments.

Hi all,
The first cond-expr patch has been committed as r16-3848-gaf53cfeb8352b1.
This patch inspired me to work on an even clearer feature: allowing
cond-expr to use characters. The change is small; we just need to
conditionally fill the string_length. I'd like to implement this
before moving on
The _GLIBCXX_MAKE_MOVE_ITERATOR macro is needed for code that needs to
compile as C++98, where it just produces the original iterator. In
std::uninitialized_move and std::uninitialized_move_n we can just call
std::make_move_iterator directly.

The changelog part of the commit message is formatted wrongly.
* gcc/match.pd: added the following optimizations
Add the SME LUTv2 architecture extension. Users can enable the extension
by adding `+sme-lutv2` to `-march` or `-mcpu`, and test for its presence
with the `__ARM_FEATURE_SME_LUTv2` macro. The intrinsics will be added
in the next commit.
