The ceil etc functions can be only inlined as instruction when

libstdc++: Fix some algos for 16-bit size_t [PR108221]
Some standard algorithms fail to compile when size_t or ptrdiff_t is
narrower than int. The __lg helper function is ambiguous if ptrdiff_t is
short or __int20, so replace it with a function template that works for
those types as well as signed/unsigned int/long/long long. The helpers
for stable_sort perform arithmetic on size values and assume the types
won't change, which isn't true if the type promotes to int.

c++: Only do maybe_init_list_as_range optimization if !processing_template_decl [PR108047]
The last testcase in this patch ICEs, because
maybe_init_list_as_range -> maybe_init_list_as_array
calls maybe_constant_init in:
/* Don't do this if the conversion would be constant. */
first = maybe_constant_init (first);
if (TREE_CONSTANT (first))
return NULL_TREE;
but maybe_constant_init shouldn't be called when processing_template_decl.
While we could replace that call with fold_non_dependent_init, my limited
understanding is that this is an optimization and even if we don't optimize
it when processing_template_decl, build_user_type_conversion_1 will be
called again during instantiation with !processing_template_decl if it is
every instantiated and we can do the optimization only then.

ada: Simplify finalization of temporaries created for interface objects
The expansion of (class-wide) interface objects generates a temporary that
holds the actual data and the objects are rewritten as the renaming of the
dereference at the interface tag present in it. These temporaries may need
to be finalized and this is currently done through the renamings, by using
pattern matching to recognize the original source constructs.
Now these temporaries may also need to be adjusted and this is currently
done "naturally", i.e. by using the standard machinery for them, so there
is no fundamental reason why the finalization cannot be done this way too.
Therefore this changes removes the special machinery implemented for their
finalization and let them be handled by the standard one instead.

The problem is mismatch between the caller and callee side.
On the callee side, we do:

if (!cfun->stdarg)
data->arg.named = 1; /* No variadic parms. */
else if (DECL_CHAIN (parm))

else if (targetm.calls.strict_argument_naming (all->args_so_far))
data->arg.named = 1; /* Only variadic ones are unnamed. */
else
data->arg.named = 0; /* Treat as variadic. */
which is later passed to the target hooks to determine if a particular
argument is named or not. Now, cfun->stdarg is determined from the stdarg_p
call, which for the new C2X TYPE_NO_NAMED_ARGS_STDARG_P function types
(rettype fn (...)) returns true. Such functions have no named arguments,
so data->arg.named will be 0 in function.cc. But on the caller side,
as TYPE_NO_NAMED_ARGS_STDARG_P function types have TYPE_ARG_TYPES NULL,
we instead treat those calls as unprototyped even when they are prototyped
- /* If we know nothing, treat all args as named. */ n_named_args = num_actuals;
in 2 spots. We need to treat the TYPE_NO_NAMED_ARGS_STDARG_P cases as
prototyped with no named arguments.

indirectly by <windows.h> if `WIN32_LEAN_AND_MEAN` is not defined. The
`IXMLDOMDocument` class has a member function named `abort()`, which gets
affected by our `abort()` macro in "system.h".
`WIN32_LEAN_AND_MEAN` should, nevertheless, always be defined. This
can exclude 'APIs such as Cryptography, DDE, RPC, Shell, and Windows

libstdc++: Refactor time_zone::_Impl::rules_counter [PR108235]
Abstract the atomic counter used to synchronize access to time_zone
infos behind a Lockable class API, and use atomic_signed_lock_free
instead of atomic<int_least32_t>, as that should be the most efficient
type. (For futex-supporting targets it makes no difference, but might
benefit other targets in future.)
The new API allows the calling code to be simpler, without needing to
repeat the same error prone preprocessor conditions in multiple places.
It also allows using template metaprogramming to decide whether to use
the atomic or a mutex, which gives us more flexibility than only using
preprocessor conditions. That allows us to choose the mutex
implementation for targets such as hppa-hp-hpux11.11 where 32-bit
atomics are not lock-free and so would introduce an unwanted dependency
on libatomic.

c: C2x semantics for __builtin_tgmath
__builtin_tgmath implements <tgmath.h> semantics for integer generic
arguments that handle cases involving _FloatN / _FloatNx types as
specified in TS 18661-3 plus some defect fixes.
C2x has further changes to the semantics for <tgmath.h> macros with
such types, which should also be considered defect fixes (although
handled through the integration of TS 18661-3 in C2x rather than
through an issue tracking process). Specifically, the rules were
changed because of problems raised with using the macros with the
evaluation format types such as float_t and _Float32_t: the older
version of the rules didn't allow passing _FloatN / _FloatNx types to
the narrowing macros returning float or double, or passing float /
double / long double to the narrowing macros returning _FloatN /
_FloatNx, which was a problem with the evaluation format types which
could be either kind of type depending on the value of
FLT_EVAL_METHOD.
Thus the new rules allow cases of mixing types which were not allowed
before - which is not itself a problem for __builtin_tgmath - and, as
part of the changes, the handling of integer arguments was also
changed: if there is any _FloatNx generic argument, integer generic
arguments are treated as _Float32x (not double), while the rule about
treating integer arguments to narrowing macros returning _FloatN or
_FloatNx as _Float64 not double was removed (no longer needed now
double is a valid argument to such macros).
Implement the changes for __builtin_tgmath. (The changes also added a
rule that if any argument is _DecimalNx, integer arguments are treated
as _Decimal64x, but GCC doesn't support _DecimalNx types so nothing is
done about that.)
I have a corresponding glibc patch to update glibc test expectations
for C2x and also ensure that appropriate semantics are followed when
GCC 7 through 12 are used with <tgmath.h> (avoiding __builtin_tgmath
in cases where it doesn't match the C2x semantics).
Bootstrapped with no regressions for x86_64-pc-linux-gnu.

libstdc++: Fix deadlock in debug iterator increment [PR108288]
With -fno-elide-constructors the debug iterator post-increment and
post-decrement operators are susceptible to deadlock. They take a mutex
lock and then return a temporary, which also attempts to take a lock to
attach itself to the sequence. If the return value and *this happen to
collide and use the same mutex from the pool, then you get a deadlock
trying to lock a mutex that is already held by the current thread.
The solution is to construct the return value before taking the lock.
The copy constructor and pre-inc/pre-dec operators already manage locks
correctly, without deadlock, so just implement post-inc/post-dec in the
conventional way, taking a copy then modifying *this, then returning the

c++: class-head parsing and CPP_TEMPLATE_ID access [PR108275]
When tentatively parsing what is really an elaborated-type-specifier

CPP_TEMPLATE_ID token that later gets reused by the fallback parse if
the tentative parse fails. These special tokens also capture the access
checks that have been deferred while parsing the template-id. But here
we form such a token when the access check state is dk_no_check, and so
the token captures no access checks. This effectively bypasses access
checking for the template-id during the subsequent parse as an
elaborated-type-specifier.

This is done only becuase we stream bodies to named section and clash

testsuite: AIX
C++ Modules do not work reliably on AIX. This patch disables the
modules portion of the testsuite on AIX.
IBM128 float keywords not enabled for AIX, so skip this test.

OpenMP: GC unused SIMD clones
SIMD clones are created during the IPA phase when it is not known whether
or not the vectorizer can use them. Clones for functions with external
linkage are part of the ABI, but local clones can be GC'ed if no calls are
found in the compilation unit after vectorization.
gcc/ChangeLog
* cgraph.h (struct cgraph_node): Add gc_candidate bit, modify
default constructor to initialize it.
* cgraphunit.cc (expand_all_functions): Save gc_candidate functions
for last and iterate to handle recursive calls. Delete leftover
candidates at the end.
* omp-simd-clone.cc (simd_clone_create): Set gc_candidate bit
on local clones.
* tree-vect-stmts.cc (vectorizable_simd_clone_call): Clear
gc_candidate bit when a clone is used.
gcc/testsuite/ChangeLog
* g++.dg/gomp/target-simd-clone-1.C: Tweak to test
that the unused clone is GC'ed.
* gcc.dg/gomp/target-simd-clone-1.c: Likewise.
