Drop need for constant I in ctf test

Though I is supposed to be a constant expression, this is not the case
on vxworks, but this is not what this debug information format test is
testing for, so use real constants to initialize complex variables.

for  gcc/testsuite/ChangeLog

* gcc.dg/debug/ctf/ctf-complex-1.c: Do not test whether I is
usable in initializers.

xfail fp-uint64-convert-double-* on all arm targets

It wasn't long ago that I xfailed these tests on arm-*-eabi, but the
fail is expected on all other arm targets: even when hard float is
available, conversions between 64-bit integers and double are always
emulated on ARM, and the emulation disregards rounding modes.  So,
bump the xfail to all of arm-*-*.

for  gcc/testsuite/ChangeLog

* gcc.dg/torture/fp-uint64-convert-double-1.c: XFAIL on all of
arm-*-*.
* gcc.dg/torture/fp-uint64-convert-double-2.c: Likewise.

[arm] [testsuite] asm-flag-4.c: match quotes in expected message

Quotes were added around the "asm" keyword in the message expected by
the test, so the test needs adjusting.

for  gcc/testsuite/ChangeLog

* gcc.target/arm/asm-flag-4.c: Match quotes around "asm" in
message.

testsuite: Accept pmf-vbit-in-delta extra warning

cp_build_binary_op, that issues -Waddress warnings, issues an extra
warning on arm targets, that g++.dg/warn/Waddress-5.C does not expect
when comparing a pointer-to-member-function literal with null.

The reason for the extra warning is that, on arm targets,
TARGET_PTRMEMFUNC_VBIT_LOCATION == ptrmemfunc_vbit_in_delta, which
causes a different path to be taken, that extracts the
pointer-to-function and the delta fields (minus the vbit) and compares
each one with zero.  It's when comparing this pointer-to-function with
zero, in a recursive cp_build_binary_op, that another warning is
issued.

I suppose there should be a way to skip the warning in this recursive
call, without disabling other warnings that might be issued there, but
this patch only arranges for the test to tolerate the extra warning.

for  gcc/testsuite/ChangeLog

* g++.dg/warn/Waddress-5.C: Tolerate extra -Waddress warning.

[libstdc++] do not destruct mutex_pool mutexes

On vxworks, after destroying the semaphore used to implement a mutex,
__gthread_mutex_lock fails and __gnu_cxx::__mutex::lock calls
__throw_concurrence_lock_error.  Nothing ensures the mutex_pool
mutexes survive init-once objects containing _Safe_sequence_base.  If
such an object completes construction before mutex_pool
initialization, it will be registered for atexit destruction after the
mutex_pool mutexes, so the _M_detach_all() call in the
_Safe_sequence_base dtor will use already-destructed mutexes, and
basic_string/requirements/citerators_cc fails calling terminate.

This patch fixes this problem by ensuring the mutex pool mutexes are
constructed on demand, on a statically-allocated buffer, but never
destructed.

for  libstdc++-v3/ChangeLog

* src/c++11/shared_ptr.cc (__gnu_internal::get_mutex):
Avoid destruction of the mutex pool.

[libstdc++] xfail noreplace tests on vxworks

vxworks ignores O_EXCL in open, so noreplace open succeeds when it is
expected to fail.  xfail the tests.

for  libstdc++-v3/ChangeLog

* testsuite/27_io/basic_ofstream/open/char/noreplace.cc: xfail
on vxworks.
* testsuite/27_io/basic_ofstream/open/wchar_t/noreplace.cc:
Likewise.

[libstdc++] [testsuite] intro/names.cc: undef func on vxw7krn

The '#define func' added in 2021, to test that system headers don't
violate the user namespace, exposes such a bug in the vxworks sysLib.h
header, so add yet another such annotated workaround.

for  libstdc++-v3/ChangeLog

* testsuite/17_intro/names.cc: Undef func on vxworks >= 7 in
kernel mode.

Rust: In 'type_for_mode' langhook also consider all 'int_n' modes/types

As reported in "Rust related issues" at the end of

vect: inbranch SIMD clones

There has been support for generating "inbranch" SIMD clones for a long time,
but nothing actually uses them (as far as I can see).

This patch add supports for a sub-set of possible cases (those using
mask_mode == VOIDmode).  The other cases fail to vectorize, just as before,
so there should be no regressions.

The sub-set of support should cover all cases needed by amdgcn, at present.

RISC-V: Make the test condition more strict for gcc.target/riscv/_Float16-zhinxmin-1.c

LTO might generate random string for the section name, which might contain `mv`,
then might cause random false alarm.

gcc/testsuite/ChangeLog:

* gcc.target/riscv/_Float16-zhinxmin-1.c: Tweak test
condition.

RISC-V: Adjust vsetvl testcase.

Rust: Move void_list_node init to common code

Apply commit r13-2682-g8ff2a92a0450243e52d3299a13b30f208bafa7e0

Add '-Wno-complain-wrong-lang', and use it in 'gcc/testsuite/lib/target-supports.exp:check_compile' and elsewhere

I noticed that GCC/Rust recently lost all LTO variants in torture testing:

     PASS: rust/compile/torture/all_doc_comment_line_blocks.rs   -O0  (test for excess errors)
     PASS: rust/compile/torture/all_doc_comment_line_blocks.rs   -O1  (test for excess errors)

     PASS: rust/compile/torture/all_doc_comment_line_blocks.rs   -Os  (test for excess errors)

Etc.

The reason is that when probing for availability of LTO, we run into:

    cc1: warning: command-line option '-frust-incomplete-and-experimental-compiler-do-not-use' is valid for Rust but not for C

For GCC/Rust testing, this flag is (as of recently) defaulted in
'gcc/testsuite/lib/rust.exp:rust_init':

    lappend ALWAYS_RUSTFLAGS "additional_flags=-frust-incomplete-and-experimental-compiler-do-not-use"

A few more "command-line option [...] is valid for [...] but not for [...]"
instances were found in the test suite logs, when more than one language is
involved.

With '-Wno-complain-wrong-lang' used in
'gcc/testsuite/lib/target-supports.exp:check_compile', we get back:

     PASS: rust/compile/torture/all_doc_comment_line_blocks.rs   -O0  (test for excess errors)

In 'contrib/config-list.mk', clarify i686-symbolics-gnu to i686-gnu

Already in the first revision of 'contrib/config-list.mk', i686-symbolics-gnu
has been present, but it's not clear to me whether that was meant to be
Symbolics as in the manufacturer, <https://en.wikipedia.org/wiki/Symbolics>,
with GNU (that is, GNU/Hurd) kernel/operating system (user land), or Symbolics
kernel with GNU operating system (user land)?

I can't find any mention of "Symbolics" in the history of 'config.sub'
upstream.

Either way, GCC configures i686-symbolics-gnu exactly the same as i686-gnu:

    $ sed -n -e '/Using .* host machine hooks\.$/q' -e '/^Using the following target machine macro files:$/,$p' log/i686-gnu-make.out

            [...]/gcc/config/i386/i386.h
            [...]/gcc/config/i386/unix.h

analyzer: stop exploring the path after certain diagnostics [PR108830]

PR analyzer/108830 reports a situation in which there are lots of
followup -Wanalyzer-null-dereference warnings after the first access of
a NULL pointer, leading to very noisy output from -fanalyzer.

The analyzer's logic for stopping emitting multiple warnings from a
state machine doesn't quite work for NULL pointers: it attempts to
transition the malloc state machine's NULL pointer to the "stop" state,
which doesn't seem to make much sense in retrospect, and seems to get
confused over types.

Similarly, poisoned_value_diagnostic can be very noisy for uninit
variables, emitting a warning for every access to an uninitialized
variable.  In theory, region_model::check_for_poison makes some attempts
to suppress followups, but only for the symbolic value itself; if the
user's code keeps accessing the same region, we would get a warning on
each one.  For example, this showed up in Doom's s_sound.c where there
were 7 followup uninit warnings after the first uninit warning in
"S_ChangeMusic".

This patch adds an extra mechanism, giving pending diagnostics the
option of stopping the analysis of an execution path if they're saved
for emission on it, and turning this on for these warnings:
  -Wanalyzer-null-dereference
  -Wanalyzer-null-argument
  -Wanalyzer-use-after-free
  -Wanalyzer-use-of-pointer-in-stale-stack-frame
  -Wanalyzer-use-of-uninitialized-value

Doing so should hopefully reduce the cascades of diagnostics that
-fanalyzer can sometimes emit.

I added a -fno-analyzer-suppress-followups for the cases where you
really want the followup warnings (e.g. in some DejaGnu tests, and
for microbenchmarks of UB detection, such as PR analyzer/104224).

Integration testing shows this patch reduces the number of probable
false positives reported by 94, and finds one more true positive:

gccrs: Fix undefined behaviour issues on macos

This adds missing copy constructors to HIR::PathExprSegment which were
wrongly defaulting to empty vectors when apply specified generic arguments
to method calls.

gccrs: Add initial support for argument capture of closures

When we have a closure expression that captures a parent function's
variable we must setup the closure data to contain this. Ignoring
moveability and mutability requires for now, this patch creates the closure
structure with fields for each of the captured variables. When it comes to
compilation of the closure expression in order to support nested closures
we must setup a context of implicit mappings so that for all path
resolution we hit this implicit closure mappings lookups code before any
lookup_var_decl as this decl will not exist so the order here is important
during path resolution which is a similar problem to match expression
destructuring.

(ClosureType::clone): Pass `captures` argument.
* typecheck/rust-tyty.h: Add `captures` field.

gccrs: Add closure binding's tracking to name resolution

When we have a closure block referencing variables in a parent function,
we must track what these are. We do this by having a context of closures
so if we have a variable reference and its declared in a rib whose node id
is less than the node id of the closure's node id we know it must be a
captured variable. We also need to iterate all possible closure contexts
as we might be in the case of a nested closure.
