62c126db6b libstdc++: Implement C++26 P3378R2 - constexpr exception types 
The following patch attempts to implement the C++26 P3378R2 - constexpr
exception types paper.

This is quite complicated, because most of these classes which should
be constexpr-ized use solely or mostly out of line definitions in
libstdc++, both for historical, code size and dual ABI reasons, so that
one can throw these as exceptions between TUs with old vs. new (or vice
versa) ABIs.
For this reason, logic_error/runtime_error and classes derived from it
have the old ABI std::string object inside of them and the exported
APIs from libstdc++.so.6 ensure the right thing.

Now, because new invoked during constant evaluation needs to be deleted
during the same constant evaluation and can't leak into the constant
expressions, I think we don't have to use COW strings under the hood
(which aren't constexpr I guess because of reference counting/COW) and
we can use something else, the patch uses heap allocated std::string
object (where __cow_constexpr_string class has just a pointer to that).
As I think we still want to hide the ugly details if !consteval in the
library, the patch exports 8 __cow_string class symbols (6 existing which
were previously just not exported and 2 new ones) and if !consteval
calls those through extern "C" _Zmangled_name symbols.  The functions
are always_inline.

And then logic_error etc. have for C++26 (precisely for
__cpp_lib_constexpr_exceptions >= 202502L) constexpr definitions of
cdtors/methods.  This results in slightly larger code (a few insns at most)
at runtime for C++26, e.g. instead of calling say some logic error
cdtor/method with 2 arguments it calls some __cow_string one with 2
arguments but + 8 bytes pointer additions on both.

The patch also removes the __throw_format_error forward declaration
which apparently wasn't needed for anything as all __throw_format_error
users were either in <format> or included <format> before the uses,
reverts the
https://gcc.gnu.org/pipermail/libstdc++/2025-July/062598.html
patch and makes sure __throw_* functions (only those for exception types
which the P3378R2 or P3068R5 papers made constexpr usable and there are
actually constexpr/consteval uses of those) are constexpr for C++26
constexpr exceptions.

The patch does that by splitting the bits/functexcept.h header:
1) bits/functexcept.h stays for the __throw_* functions which are (at
least for now) never constexpr (the <ios>, <system_error>, <future>
and <functional> std::exception derived classes) or are never used
or never used in constexpr/consteval contexts (<exception>, <typeinfo>
std::exception derived classes and std::range_error).
2) bits/new_{throw,except}.h for __throw_bad_alloc/__throw_bad_array_new_length
and std::bad_alloc/std::bad_array_new_length (where <new> includes
<bits/new_except.h> and <bits/new_throw.h> as well for the C++26 constexpr
exceptions case)
3) for the most complicated <stdexcept> stuff, one header
addition to bits/stdexcept.h one header for the __throw_logic_error etc.
forward declarations, one header for the __throw_logic_error etc.
definitions and one header without header guards which will
depending on __glibcxx_exc_in_string include one or the other because
<string> vs. <string_view> vs. <stdexcept> have heavy interdependencies

45ab93d9af non-gcc: Remove trailing whitespace 
I've tried to build stage3 with
-Wleading-whitespace=blanks -Wtrailing-whitespace=blank -Wno-error=leading-whitespace=blanks -Wno-error=trailing-whitespace=blank
added to STRICT_WARN and that expectably resulted in about
2744 unique trailing whitespace warnings and 124837 leading whitespace
warnings when excluding *.md files (which obviously is in big part a
generator issue).  Others from that are generator related, I think those
need to be solved later.

The following patch just fixes up the easy case (trailing whitespace),
which could be easily automated:
for i in `find . -name \*.h -o -name \*.cc -o -name \*.c | xargs grep -l '[ 	]$' | grep -v testsuite/`; do sed -i -e 's/[ 	]*$//' $i; done
I've excluded files which I knew are obviously generated or go FE.

Is there anything else we'd want to avoid the changes?

Due to patch size, I've split it between gcc/ part
and rest (include/, libiberty/, libgcc/, libcpp/, libstdc++-v3/;
this part).

8cf51d7516 libstdc++: Fix std::allocator_traits::construct constraints [PR108619] 
Using std::is_constructible in the constraints introduces a spurious
dependency on the type being destructible, which should not be required
for constructing with an allocator. The test case shows a case where the
type has a private destructor, which can be destroyed by the allocator,
but std::is_destructible and std::is_constructible are false.

Similarly, using is_nothrow_constructible in the noexcept-specifiers
for the construct members of allocator_traits and std::allocator,
__gnu_cxx::__new_allocator, and __gnu_cxx::__malloc_allocator gives the
wrong answer if the type isn't destructible.
We need a new type trait to define those correctly, so that we only
check if the placement new-expression is nothrow after using
is_constructible to check that it would be well-formed.

Instead of just fixing the overly restrictive constraint to check for
placement new, rewrite allocator_traits in terms of 'if constexpr' using
variable templates and the detection idiom.

Although we can use 'if constexpr' and variable templates in C++11 with
appropriate uses of diagnostic pragmas, we can't have constexpr
functions with multiple return statements. This means that in C++11 mode
the _S_nothrow_construct and _S_nothrow_destroy helpers used for
noexcept-specifiers still need to be overlaods using enable_if. Nearly
everything else can be simplified to reduce overload resolution and
enable_if checks.

libstdc++-v3/ChangeLog:

	PR libstdc++/108619
	* include/bits/alloc_traits.h (__allocator_traits_base): Add
	variable templates for detecting which allocator operations are
	supported.
	(allocator_traits): Use 'if constexpr' instead of dispatching to

	(allocator_traits<allocator<T>>::construct): Use Construct if
	construct_at is not supported. Use

03d3aeb0e0 libstdc++: Do not use C++11 alignof in C++98 mode [PR104395] 
When -faligned-new (or Clang's -faligned-allocation) is used our
allocators try to support extended alignments, gated on the
__cpp_aligned_new macro. However, because they use alignof(_Tp) which is
not a keyword in C++98 mode, using -std=c++98 -faligned-new results in
errors from <memory> and other headers.

We could change them to use __alignof__ instead of alignof, but that
would potentially alter the result of the conditions, because e.g.
alignof(long long) != __alignof__(long long) on some targets. That's
probably not an issue for any types with extended alignment, so maybe it
would be a safe change.

For now, it seems acceptable to just disable the extended alignment
support in C++98 mode, so that -faligned-new enables std::align_val_t
and the corresponding operator new overloads, but doesn't affect
std::allocator, __gnu_cxx::__bitmap_allocator etc.

b1983f4582 libstdc++: Avoid errors in allocator's noexcept-specifier (PR 89510) 
This fixes a regression due to the conditional noexcept-specifier on
std::allocator::construct and std::allocator::destroy, as well as the
corresponding members of new_allocator, malloc_allocator, and
allocator_traits. Those noexcept-specifiers were using expressions which
might be ill-formed, which caused errors outside the immediate context
when checking for the presence of construct and destroy in SFINAE
contexts.

The fix is to use the is_nothrow_constructible and
is_nothrow_destructible type traits instead, because those traits are
safe to use even when the construction/destruction itself is not valid.

The is_nothrow_constructible trait will be false for a type that is not
also nothrow-destructible, even if the new-expression used in the
construct function body is actually noexcept. That's not the correct
answer, but isn't a problem because providing a noexcept-specifier on
these functions is not required by the standard anyway. If the answer is
false when it should be true, that's suboptimal but OK (unlike giving
errors for valid code, or giving a true answer when it should be false).

85f2411493 PR c++/91369 Implement P0784R7 changes to allocation and construction 
This patch is the first part of library support for constexpr
std::vector and std::string. This only includes the changes to
std::allocator, std::allocator_traits, std::construct_at,
std::destroy_at, std::destroy and std::destroy_n.

std::allocator::allocate and std::allocator::deallocate need to be
added so that they can be intercepted by the compiler during constant
evaluation. Outside of constant evaluation those new member functions
just forward to the existing implementation in the base class.

3263fb9c6b Remove using-declarations that add std names to __gnu_cxx 
These using-declarations appear to have been added for simplicity when
moving the non-standard extensions from namespace std to namespace

unportable uses like __gnu_cxx::size_t and __gnu_cxx::pair, which serve
no useful purpose.

c7790bdbd9 Make ext allocators support heterogeneous equality comparison 
The Allocator requirements include the ability to compare different
specializations of the same allocator class template. This did not work
for __gnu_cxx::new_allocator and other extension allocators.  This patch
replaces the equality operators for those allocators with inline friends
that support heterogeneous comparisons.  (I'm not changing all ext
allocators because some are bit-rotted already).

Additionally, the equality operators for comparing two std::allocator
objects of the same type are now defined as inline friends. Those
overloads don't need to be declared at namespace scope, because they
aren't specified in the standard (but they're needed in this
implementation to avoid ambiguities caused by the extra overloads
defined for the base allocator type).

	* include/bits/allocator.h
	(operator==(const allocator<_Tp>&, const allocator<_Tp>))
	(operator!=(const allocator<_Tp>&, const allocator<_Tp>)): Replace
	with inline friends.

422a9f7789 PR libstdc++/87544 limit max_size() to PTRDIFF_MAX / sizeof(T) 
The C++17 standard requires the default implementation for
allocator_traits::max_size to return SIZE_MAX / sizeof(value_type).
That causes GCC to warn because the value could be larger than can
sensibly be passed to malloc. This patch changes the new_allocator and
malloc_allocator max_size() members to use PTRDIFF_MAX instead of
SIZE_MAX (and because they define it, the allocator_traits default isn't
used). This also changes vector::max_size to impose a sensible limit
using PTRDIFF_MAX for cases where the value from the allocator or
allocator_traits is not sensible.
