Clarify that FSF copyright notices in tests are incorrect for
contributions under DCO terms. Clarify the sentence about copying
existing tests to clarify that it is only referring to copying the code

This patch implements C++26 function_ref as specified in P0792R14,
with correction for constraints for constructor accepting nontype_t
parameter from LWG 4256.
As function_ref may store a pointer to the const object, __Ptrs::_M_obj is
changed to const void*, so again we do not cast away const from const
objects. To help with necessary casts, a __polyfunc::__cast_to helper is
added, that accepts reference to or target type direclty.
The _Invoker now defines additional call methods used by function_ref:
_S_ptrs() for invoking target passed by reference, and __S_nttp, _S_bind_ptr,
_S_bind_ref for handling constructors accepting nontype_t. The existing
_S_call_storage is changed to thin wrapper, that initialies _Ptrs, and forwards
to _S_call_ptrs.
This reduced the most uses of _Storage::_M_ptr and _Storage::_M_ref,
so this functions was removed, and _Manager uses were adjusted.
Finally we make function_ref available in freestanding mode, as
move_only_function and copyable_function are currently only available in hosted,
so we define _Manager and _Mo_base only if either __glibcxx_move_only_function
or __glibcxx_copyable_function is defined.

In r8-7777-g25949ee33201f2 I updated some URLs to point to copies of the

all the other pages would be too. Apparently that's not how the Wayback
Machine works, and each page is archived on a different date. That meant

This patch implements C++26 copyable_function as specified in P2548R6.
It also implements LWG 4255 that adjust move_only_function so constructing
from empty copyable_function, produces empty functor. This falls from
existing checks, after specializing __is_polymorphic_function_v for
copyable_function specializations.
For compatible invoker signatures, the move_only_function may be constructed
from copyable_funciton without double indirection. To achieve that we derive
_Cpy_base from _Mo_base, and specialize __is_polymorphic_function_v for
copyable_function. Similary copyable_functions with compatible signatures
can be converted without double indirection.
As we starting to use _Op::_Copy operation from the _M_manage function,
invocations of that functions may now throw exceptions, so noexcept needs
to be removed from the signature of stored _M_manage pointers. This also
affects operations in _Mo_base, however we already wrap _M_manage invocations
in noexcept member functions (_M_move, _M_destroy, swap).

The gcc4-compatible copy-on-write std::string does not conform to the
C++11 requirements on data race avoidance in standard containers.
Specifically, calling non-const member functions such as begin() and
data() needs to do the "copy on write" operation and so is most
definitely a modification of the object. As such, those non-const
members must not be called concurrently with any other uses of the
string object.

This attempts to simplify and clean up our std::hash code. The primary
benefit is improved diagnostics for users when they do something wrong
involving std::hash or unordered containers. An additional benefit is
that for the unstable ABI (--enable-symvers=gnu-versioned-namespace) we
can reduce the memory footprint of several std::hash specializations.
In the current design, __hash_enum is a base class of the std::hash
primary template, but the partial specialization of __hash_enum for
non-enum types is disabled. This means that if a user forgets to
specialize std::hash for their class type (or forgets to use a custom
hash function for unordered containers) they get error messages about
std::__hash_enum not being constructible. This is confusing when there
is no enum type involved: why should users care about __hash_enum not
being constructible if they're not trying to hash enums?
This change makes the std::hash primary template only derive from
__hash_enum when the template argument type is an enum. Otherwise, it
derives directly from a new class template, __hash_not_enabled. This new
class template defines the deleted members that cause a given std::hash
specialization to be a disabled specialization (as per P0513R0). Now
when users try to use a disabled specialization, they get more
descriptive errors that mention __hash_not_enabled instead of
__hash_enum.
Additionally, adjust __hash_base to remove the deprecated result_type
and argument_type typedefs for C++20 and later.
In the current code we use a __poison_hash base class in the std::hash
specializations for std::unique_ptr, std::optional, and std::variant.
The primary template of __poison_hash has deleted special members, which
is used to conditionally disable the derived std::hash specialization.
This can also result in confusing diagnostics, because seeing "poison"
in an enabled specialization is misleading. Only some uses of
__poison_hash actually "poison" anything, i.e. cause a specialization to
be disabled. In other cases it's just an empty base class that does
nothing.
This change removes __poison_hash and changes the std::hash
specializations that were using it to conditionally derive from
__hash_not_enabled instead. When the std::hash specialization is
enabled, there is no more __poison_hash base class. However, to preserve
the ABI properties of those std::hash specializations, we need to
replace __poison_hash with some other empty base class. This is needed
because in the current code std::hash<std::variant<int, const int>> has
two __poison_hash<int> base classes, which must have unique addresses,
so sizeof(std::hash<std::variant<int, const int>>) == 2. To preserve
this unfortunate property, a new __hash_empty_base class is used as a
base class to re-introduce du0plicate base classes that increase the
class size. For the unstable ABI we don't use __hash_empty_base so the
std::hash<std::variant<T...>> specializations are always size 1, and
the class hierarchy is much simpler so will compile faster.
Additionally, remove the result_type and argument_type typedefs from all
disabled specializations of std::hash for std::unique_ptr,
std::optional, and std::variant. Those typedefs are useless for disabled
specializations, and although the standard doesn't say they must *not*
be present for disabled specializations, it certainly only requires them
for enabled specializations. Finally, for C++20 the typedefs are also
removed from enabled specializations of std::hash for std::unique_ptr,
std::optional, and std::variant.

add deprecation warnings to them, which can be disabled with
-Wno-deprecated. For C++20 and later these headers are no longer in the
standard at all, so compiling with _GLIBCXX_USE_DEPRECATED defined to 0
will give an error when they are included.
Because #warning is non-standard before C++23 we need to use pragmas to
ignore -Wc++23-extensions for the -Wsystem-headers -pedantic case.
One g++ test needs adjustment because it includes <ciso646>, but that
can be made conditional on the __cplusplus value without any reduction
in test coverage.
For the library tests, consolidate the std_c++0x_neg.cc XFAIL tests into
the macros.cc test, using dg-error with a { target c++98_only }
selector. This avoids having two separate test files, one for C++98 and
one for everything later. Also add tests for the <xxx.h> headers to
ensure that they behave as expected and don't give deprecated warnings.

Too many users don't know about -D_GLIBCXX_ASSERTIONS and so are missing
valuable checks for C++ standard library preconditions. This change
enables libstdc++ assertions by default when compiling with -O0 so that
we diagnose more bugs by default.
When users enable optimization we don't add the assertions by default
(because they have non-zero overhead) so they still need to enable them
manually.
For users who really don't want the assertions even in unoptimized
builds, defining _GLIBCXX_NO_ASSERTIONS will prevent them from being
enabled automatically.

[PR61458]
This simplifies the implementation of std::aligned_storage. For the
unstable ABI it also fixes the bug where its size is too large when the
default alignment is used. We can't fix that for the stable ABI though,
so just add a comment about the bug.
libstdc++-v3/ChangeLog:
PR libstdc++/61458
* doc/doxygen/user.cfg.in (GENERATE_BUGLIST): Set to NO.
* include/std/type_traits (__aligned_storage_msa): Remove.
(__aligned_storage_max_align_t): New struct.
(__aligned_storage_default_alignment): New function.
(aligned_storage): Use __aligned_storage_default_alignment for
default alignment. Replace union with a struct containing an
aligned buffer. Improve Doxygen comment.
(aligned_storage_t): Use __aligned_storage_default_alignment for
default alignment.

There are several features that are not supported when using the old

This makes durations, time points and calendrical types available for

used to explicitly disable <chrono> for freestanding.
