24f2764521 libstdc++: Remove tests for self-move debug assertions
I recently removed the debug mode checks for self-move assignment, which
means these tests now fail when _GLIBCXX_DEBUG is added to the options
or when the check-debug target is used. Remove all the tests.

c2fb0a1a2e libstdc++: Make self-move well-defined for containers [PR 85828]
The C++ LWG recently confirmed that self-move assignment should not have
undefined behaviour for standard containers (see the proposed resolution
of LWG 2839). The result should be a valid but unspecified value, just
like other times when a container is moved from.

Our std::list, std::__cxx11::basic_string and unordered containers all
have bugs which result in undefined behaviour.

For std::list the problem is that we clear the previous contents using
_M_clear() instead of clear(). This means the _M_next, _M_prev and
_M_size members are not zeroed, and so after we "update" them (with
their existing values), we are left with dangling pointers and a
non-zero size, but no elements.

For the unordered containers the problem is similar. _Hashtable first
deallocates the existing contents, then takes ownership of the pointers
from the RHS object (which has just had its contents deallocated so the
pointers are dangling).

For std::basic_string it's a little more subtle. When the string is
local (i.e. fits in the SSO buffer) we use char_traits::copy to copy the
contents from this->data() to __rhs.data(). When &__rhs == this that
copy violates the precondition that the ranges don't overlap. We only
need to check for self-move for this case where it's local, because the
only other case that can be true for self-move is that it's non-local
but the allocators compare equal. In that case the data pointer is
neither deallocated nor leaked, so the result is well-defined.

This patch also makes a small optimization for std::deque move
assignment, to use the efficient move when is_always_equal is false, but
the allocators compare equal at runtime.

Finally, we need to remove all the Debug Mode checks which abort the
program when a self-move is detected, because it's not undefined to do
that.

Before PR 85828 can be closed we should also look into fixing
std::shuffle so it doesn't do any redundant self-swaps.

eca833b812 libstdc++: Make debug containers prefer copy ctor to base ctor (PR 90102)
When given a type which can convert to any container-like type, the
C(const C&) copy constructor and C(const C::_Base&) converting
constructor are ambiguous. This change replaces the converting
constructor's parameter with a reference_wrapper-like type so that
calling that constructor requires an additional user-defined conversion.
This gives it a lower rank than the copy constructor, avoiding the
ambiguity.

While testing this change I discovered that __gnu_debug::forward_list
doesn't have a convering constructor from the std::forward_list base, so
this adds it.

We should probably consider whether the converting constructors should
be 'explicit' but I'm not changing that now.

47519a5687 PR libstdc++/92124 fix incorrect container move assignment
The container requirements say that for move assignment "All existing
elements of [the target] are either move assigned or destroyed". Some of
our containers currently use __make_move_if_noexcept which makes the
move depend on whether the element type is nothrow move constructible.
This is incorrect, because the standard says we must move assign, not
move or copy depending on the move constructor.

Use make_move_iterator instead so that we move unconditionally. This
ensures existing elements won't be copy assigned.

a2dbc0bf2a Fix tests that fail in C++2a mode
The GNU extension that allows using the wrong allocator type with a
container is disabled for C++2a mode, because the standard now requires
a diagnostic. Fix the tests that fail when -std=gnu++2a is used.

Also remove some reundant tests that are duplicates of another test
except for a target specifier of c++11. Those tests previously set
-std=gnu++11 explicitly but that was replaced globally with a target
specifier. These tests existed to verify that explicit instantiation
worked for both C++98 and C++11 modes, but now do nothing because both
copies of the test use -std=gnu++14 by default. Instead of duplicating
the test we should be regularly running the whole testsuite with
different -std options.

ebaf365963 Enforce allocator::value_type consistency for containers in C++2a
In previous standards it is undefined for a container and its allocator
to have a different value_type. Libstdc++ has traditionally allowed it
as an extension, automatically rebinding the allocator to the
container's value_type. Since GCC 8.1 that extension has been disabled
for C++11 and later when __STRICT_ANSI__ is defined (i.e. for
-std=c++11, -std=c++14, -std=c++17 and -std=c++2a).

Since the acceptance of P1463R1 into the C++2a draft an incorrect
allocator::value_type now requires a diagnostic. This patch implements
that by enabling the static_assert for -std=gnu++2a as well.

544be2beb1 Remove Profile Mode, deprecated since GCC 7.1
The Profile Mode extension is not used by anybody, nor maintained by
anybody. The containers do not support the full API specified in recent

much modern C++ code. The heuristics that would check the profile
information and make useful suggestions never materialized, so it isn't
useful.

5a58e967b5 PR c++/90047 - ICE with enable_if alias template.
In order to make alias templates useful for SFINAE we instantiate them under
the prevailing 'complain' argument, so an error encountered while
instantiating during SFINAE context is silent.  The problem in this PR comes
when we later look up the erroneous instantiation and don't give an error at
that point.  Fixed by not adding an erroneous instantiation to the hash
table, so we instantiate it again when needed and get the error.  This
required changes to a number of tests, which previously said "substitution
failed:" with no explanation of what the failure was; now we properly
explain.

This currently checks _GLIBCXX_USE_DUAL_ABI which is incorrect, as that
can be true when _GLIBCXX_USE_CXX11_ABI == 0. The correct check would be
_GLIBCXX_USE_CXX11_ABI == 1, but that's made redundant by the cxx11-abi
effective target that the test requires. However, the test will fail if

9ca2ac699a Forward declare debug containers so std::pmr aliases work
Prior to this change, including a <debug/xxx> header when _GLIBCXX_DEBUG
is also defined would fail to compile in C++17 or later. The <debug/xxx>
header would include the standard <xxx> header which defined
std::pmr::xxx as an alias for std::xxx. But in Debug Mode std::xxx
refers to std::__debug::xxx which has not been defined yet (because it
is in <debug/xxx> after the inclusion of <xxx>).

This adds declarations of the debug containers before including the
non-Debug Mode <xxx> header, so that the std::pmr::xxx aliases work.

ef45724acd P0646R1 Improving the Return Value of Erase-Like Algorithms I
In C++2a the remove, remove_if and unique members of std::list and
std::forward_list have been changed to return the number of elements
removed. This is an ABI change for the remove members and the
non-template unique members, so an abi-tag is used to give those symbols
new mangled names in C++2a mode. For the function templates the return
type is part of the mangled name so no abi-tag is needed.

	* include/bits/forward_list.h (__cpp_lib_list_remove_return_type):
	Define.
	(forward_list::__remove_return_type): Define typedef as size_type or
	void, according to __cplusplus value.
	(_GLIBCXX_FWDLIST_REMOVE_RETURN_TYPE_TAG): Define macro as abi-tag or

	* include/bits/forward_list.tcc (_GLIBCXX20_ONLY): Define macro.
