    • PR libstdc++/89130 restore support for non-MoveConstructible types · 258bd1d6 
      The changes to "relocate" std::vector elements can lead to new errors
outside the immediate context, because moving the elements to new
storage no longer makes use of the move-if-noexcept utilities. This
means that types with deleted moves no longer degenerate to copies, but
are just ill-formed. The errors happen while instantiating the
noexcept-specifier for __relocate_object_a, when deciding whether to try
to relocate.

This patch introduces indirections to avoid the ill-formed
instantiations of std::__relocate_object_a. In order to avoid using
if-constexpr prior to C++17 this is done by tag dispatching. After this
patch all uses of std::__relocate_a are guarded by checks that will
support sensible code (i.e. code not using custom allocators that fool
the new checks).

	PR libstdc++/89130
	* include/bits/alloc_traits.h (__is_copy_insertable_impl): Rename to
	__is_alloc_insertable_impl. Replace single type member with two
	members, one for each of copy and move insertable.
	(__is_move_insertable): New trait for internal use.
	* include/bits/stl_vector.h (vector::_S_nothrow_relocate(true_type))
	(vector::_S_nothrow_relocate(true_type)): New functions to
	conditionally check if __relocate_a can throw.
	(vector::_S_use_relocate()): Dispatch to _S_nothrow_relocate based
	on __is_move_insertable.
	(vector::_S_do_relocate): New overloaded functions to conditionally
	call __relocate_a.
	(vector::_S_relocate): New function that dispatches to _S_do_relocate
	based on _S_use_relocate.
	* include/bits/vector.tcc (vector::reserve, vector::_M_realloc_insert)
	(vector::_M_default_append): Call _S_relocate instead of __relocate_a.
	* testsuite/23_containers/vector/modifiers/push_back/89130.cc: New.

    • PR libstdc++/89090 avoid C++17 features in C++11/C++14 code · 27812872 
      Although GCC and Clang both allow these features pre-C++17 in system
headers, Clang does issue warnings with -Wsystem-headers. It can also
complicate bisection and/or testcase reduction if # line markers are
stripped, because the code won't be known to come from system headers.

	PR libstdc++/89090
	* include/bits/stl_uninitialized.h (__relocate_a_1): Make unused
	parameter unnamed. Add message to static assertion.
	* include/bits/vector.tcc (vector::reserve, vector::_M_realloc_insert)
	(vector::_M_default_append): Use _GLIBCXX17_CONSTEXPR for if constexpr
	in C++11 code.

    • [PR87770] test partial specializations for type dependence · e1bbb0bc 
      When instantiating a partial specialization of a template member
function for a full specialization of a class template, we test
whether the context of variables local to the partial specialization,
i.e., the partial specialization itself, is dependent, and this ICEs
in type_dependent_expression_p, when checking that the function type
isn't type-dependent because it is not in a type-dependent scope.

We shouldn't have got that far: the previous block in
type_dependent_expression_p catches cases in which the function itself
takes template arguments of its own, but it only did so for primary
templates, not for partial specializations.  This patch fixes that.

	(type_dependent_expression_p): Use it.
