cris: update recent patterns. Simplify cris_select_cc_mode.
The code in cris_select_cc_mode for selecting CC_NZmode was
partly inconsistent with the comment and partly seemed
ambiguous. I couldn't find a reason why I qualified selection
of CC_NZmode on the setting operation once a matching user was
spotted, so I just removed that. The cris.c update was due to
observing the new test-case failing; the CC_NZmode compare
wasn't eliminated.

Extend store merging to STRING_CST
The GIMPLE store merging pass doesn't merge STRING_CSTs in the general
case, although they are accepted by native_encode_expr; the reason is
that the pass only works with integral modes, i.e. with chunks whose
size is a power of two.
There are two possible ways of extending it to handle STRING_CSTs:
1) lift the condition of integral modes and treat STRING_CSTs as
other _CST nodes but with arbitrary size; 2) implement a specific
and separate handling for STRING_CSTs.
The attached patch implements 2) for the following reasons: on the
one hand, even in Ada where character strings are first-class citizens,
cases where merging STRING_CSTs with other *_CST nodes would be possible
are quite rare in practice; on the other hand, string concatenations
happen more naturally and frequently thanks to the "&" operator, giving
rise to merging opportunities.

nvptx: Fix ICE in nvptx_vector_alignment on gcc.dg/attr-vector_size.c
This patch addresses the ICE in gcc.dg/attr-vector_size.c during

testsuite/gcc.dg/attr-vector_size.c:29:1: internal compiler error: \
in tree_to_shwi, at tree.c:7321
0xf53bf2 tree_to_shwi(tree_node const*)
../../gcc/gcc/tree.c:7321
0xff1969 nvptx_vector_alignment
../../gcc/gcc/config/nvptx/nvptx.c:5105^M
The problem is that the caller has ensured that TYPE_SIZE(type) is
representable as an unsigned HOST_WIDE_INT, but nvptx_vector_alignment is
accessing it as a signed HOST_WIDE_INT which overflows in pathological
conditions. Amongst those pathological conditions is that a TYPE_SIZE of
zero can sometimes reach this function, prior to an error being emitted.
Making sure the result is not less than the mode's alignment and not greater
than BIGGEST_ALIGNMENT fixes the ICEs, and generates the expected
compile-time error messages.
Tested on --target=nvptx-none, with a "make" and "make check" which results
in four fewer unexpected failures and three more expected passes.

c++: Support C++20 virtual consteval functions. [PR88335]
Jakub's partial implementation of consteval virtual had trouble with the
current ABI requirement that we omit the vtable slot for a consteval virtual
function; it's difficult to use the normal code for constant evaluation and
also magically make the slots disappear if the vtables get written out. I
notice that Clang trunk also doesn't implement that requirement, and it
seems unnecessary to me; I expect consteval virtual functions to be
extremely rare, so it should be fine to just give them a vtable slot as
normal but put zero in it if the vtable gets emitted. I've commented as
much to the ABI committee.
One of Jakub's testcases points out that we weren't handling thunks in
our constexpr virtual handling; that is fixed here as well.
Incidentally, being able to use C++11 range-for definitely simplified

Redefine NULL to nullptr
Bootstrap with musl libc fails with numerous "missing sentinel in
function call" errors. This is because musl defines NULL as 0L for C++,
but gcc requires sentinel value to be a pointer or __null.
Jonathan Wakely says:
To be really safe during stage 1, GCC should not use NULL as a
pointer sentinel in C++ code anyway.
The bootstrap compiler could define it to 0 or 0u, neither of which
is guaranteed to be OK to pass as a varargs sentinel where a null
pointer is expected. Any of (void*)0 or (void*)NULL or nullptr
would be safe.
While it is possible to fix this by replacing NULL sentinels with
nullptrs, such approach would generate backporting conflicts, therefore
simply redefine NULL to nullptr at the end of system.h, where it would
not confuse system headers.

tree-cfg: Fix ICE with switch stmt to unreachable opt and forced labels [PR95857]
The following testcase ICEs, because during the cfg cleanup, we see:
switch (i$e_11) <default: <L12> [33.33%], case -3: <lab2> [33.33%], case 0: <L10> [33.33%], case 2: <lab2> [33.33%]>
...
lab2:
__builtin_unreachable ();
where lab2 is FORCED_LABEL. The way it works, we go through the case labels
and when we reach the first one that points to gimple_seq_unreachable*
basic block, we remove the edge (if any) from the switch bb to the bb
containing the label and bbs reachable only through that edge we've just
removed. Once we do that, we must throw away all other cases that use
the same label (or some other labels from the same bb we've removed the edge
to and the bb). To avoid quadratic behavior, this is not done by walking
all remaining cases immediately before removing, but only when processing
them later.
For normal labels this works, fine, if the label is in a deleted bb, it will
have NULL label_to_block and we handle that case, or, if the unreachable bb
has some other edge to it, only the edge will be removed and not the bb,
and again, find_edge will not find the edge and we only remove the case.
And if a label would be to some other block, that other block wouldn't have
been removed earlier because there would be still an edge from the switch
block.
Now, FORCED_LABEL (and I think DECL_NONLOCAL too) break this, because
those labels aren't removed, but instead moved to some surrounding basic
block. So, when we later process those, when their gimple_seq_unreachable*
basic block is removed, label_to_block will return some unrelated block
(in the testcase the switch bb), so we decide to keep the case which doesn't
seem to be unreachable, but we don't really have an edge from the switch
block to the block the label got moved to.
I thought first about punting in gimple_seq_unreachable* on
FORCED_LABEL/DECL_NONLOCAL labels, but that might penalize even code that
doesn't care, so this instead just makes sure that for
FORCED_LABEL/DECL_NONLOCAL labels that are being removed (and thus moved
randomly) we remember in a hash_set the fact that those labels should be
treated as removed for the purpose of the optimization, and later on
handle those labels that way.

vect: Fix an ICE in exact_div [PR95961]
In the test case for PR95961, vectorization factor computed
by vect_determine_vectorization_factor is [8,8]. But this is
updated to [1,1] later by vect_update_vf_for_slp. When we call
vect_get_num_vectors in vect_enhance_data_refs_alignment, the number
of scalars which is based on the vectorization factor is not a multiple
of the the number of elements in the vector type. This leads to
the ICE. This isn't a simple stream of contiguous vector accesses.
It's hard to predict from the available information how many vector
accesses we'll actually need per iteration. As discussed, here we
should use the number of scalars instead of the number of vectors as
an upper bound for the loop saving info about DR in the hash table.

aarch64: Treat GNU and Advanced SIMD vectors as distinct [PR92789, PR95726]
PR95726 is about template look-up for things like:
foo<float vecf __attribute__((vector_size(16)))>
foo<float32x4_t>
The immediate cause of the problem is that the hash function usually
returns different hashes for these types, yet the equality function
thinks they are equal. This then raises the question of how the types
are supposed to be treated.
I think the answer is that the GNU vector type should be treated as
distinct from float32x4_t, not least because the two types mangle
differently. However, each type should implicitly convert to the other.
This would mean that, as far as the PR is concerned, the hashing
function is right to (sometimes) treat the types differently and
the equality function is wrong to treat them as the same.
The most obvious way to enforce the type difference is to use a
target-specific type attribute. That on its own is enough to fix
the PR. The difficulty is deciding whether the knock-on effects
are acceptable.
One obvious effect is that GCC then rejects:
typedef float vecf __attribute__((vector_size(16)));
vecf x;
float32x4_t &z = x;
on the basis that the types are no longer reference-compatible.
I think that's again the correct behaviour, and consistent with
current Clang.
A trickier question is whether:
vecf x;
float32x4_t y;
… c ? x : y …
should be valid, and if so, what its type should be [PR92789].
As explained in the comment in the testcase, GCC and Clang both
accepted this, but GCC chose the “then” type while Clang chose
the “else” type. This can lead to different mangling for (probably
artificial) corner cases, as seen for “sel1” and “sel2” in the
testcase.
Adding the attribute makes GCC reject the conditional expression
as ambiguous. I think that too is the correct behaviour, for the
reasons described in the testcase. However, it does seem to have
the potential to break existing code.
It looks like aarch64_comp_type_attributes is missing cases for
the SVE attributes, but I'll handle that in a separate patch.

c++: Tweak function cloning names

Anyway, this patch makes the newly renamed copy_fndecl_with_name
static, and adds a wrapper copy_operator_fn, that takes an operator
code. The cdtor cloning functions are renamed to explicitly note they

arm: Warn if IRQ handler is not compiled with -mgeneral-regs-only [PR target/94743]
The interrupt attribute does not guarantee that the FP registers are
saved, which can result in problems difficult to debug.
Saving the FP registers and status registers can be a large penalty,
so it's probably not desirable to do that all the time.
If the handler calls other functions, we'd likely need to save all of
them, for lack of knowledge of which registers they actually clobber.
This is even more obscure for the end-user when the compiler inserts
calls to helper functions such as memcpy (some multilibs do use FP
registers to speed it up).
In the PR, we discussed adding routines in libgcc to save the FP
context and saving only locally-clobbered FP registers, but this seems
to be too much work for the purpose, given that in general such
handlers try to avoid this kind of penalty.
I suspect we would also want new attributes to instruct the compiler
that saving the FP context is not needed.
In the mean time, emit a warning to suggest re-compiling with
-mgeneral-regs-only. Note that this can lead to errors if the code
uses floating-point and -mfloat-abi=hard, eg:
argument of type 'double' not permitted with -mgeneral-regs-only
This can be troublesome for the user, but at least this would make
him aware of the latent issue.
The patch adds several testcases:
- pr94734-1-hard.c checks that a warning is emitted when using
-mfloat-abi=hard. Function IRQ_HDLR_Test can make implicit calls to
runtime floating-point routines (or direct use of FP instructions),
IRQ_HDLR_Test2 doesn't. We emit a warning in both cases, though.
- pr94734-1-softfp.c: same as above wih -mfloat-abi=softfp.
- pr94734-1-soft.c checks that no warning is emitted when using
-mfloat-abi=soft when the same code as above.
- pr94734-2.c checks that no warning is emitted when using
-mgeneral-regs-only.
- pr94734-3.c checks that no warning is emitted when using
-mgeneral-regs-only even using float-point data.

Use CHARACTER(kind) string for calculating the type hash.
This regression came about because of a change in the way
types are displayed in error messages. The character
representation is also used to calculate the hashes for
our types, so this patch restores the old behavior if
we are indeed calculating a hash.
The test case also checks for the specific hash value because
changing that would be an ABI change, which we should not
be doing unintentionally.

c-family: Avoid ICEs on calls to internal functions [PR95963]
The following testcase ICEs since recent Martin's -Wnonnull changes,
we see a CALL_EXPR and ICE because CALL_EXPR_FN is NULL, which is
valid for internal function calls. Internal function calls don't have a
function type, and will never have format_arg attribute on them nor will
serve as the i18n routines -Wformat cares about.

coroutines: Collect the function body rewrite code.
The standard describes a rewrite of the body of the user-authored
function (which wraps it in a try-catch block and provides the
initial and final suspend expressions). The exact arrangement of
this was still in flux right up until the DIS and as a consequence
was a bit of a moving target.
The net result was a fragmented implementation of the parts of
the rewrite which is now impeding progress in fixing other issues.
This patch collates the rewrite action into a single function and
carries this out earlier.
