PR libstdc++/92059
* include/tr2/dynamic_bitset (__dynamic_bitset_base): Define all
special member functions as defaulted. Add noexcept to most members.
(__dynamic_bitset_base(size_t, unsigned long long, const _Alloc&)):
Mask off unwanted bits in the __val parameter. Avoid undefined left
shifts.
(__dynamic_bitset_base::_M_assign): Remove.
(__dynamic_bitset_base::_M_do_reset): Use std::fill.
(__dynamic_bitset_base::_M_are_all_aux): Avoid integer promotion when
block_type has lower rank than int.
(dynamic_bitset): Add noexcept to most members. Use injected-class-name
in return types and parameter types.
(dynamic_bitset::_M_Nb): Add default member initializer.
(dynamic_bitset(), dynamic_bitset(const dynamic_bitset&)): Define as
defaulted.
(dynamic_bitset(dynamic_bitset&&)): Clear source object after move.
(dynamic_bitset::operator=(const dynamic_bitset&)): Define as
defaulted.
(dynamic_bitset::operator=(dynamic_bitset&&)): Add noexcept-specifier.
Define without using swap, to propagate allocator correctly.
(dynamic_bitset(const char*, const _Alloc&)): Use strlen.
(dynamic_bitset::_M_do_sanitize, dynamic_bitset::_M_do_fill): Use
casts to avoid unwanted integer promotions.
(dynamic_bitset::_M_copy_from_ptr): Rearrange template parameters and
add default template arguments and default argument to simplify usage.
(dynamic_bitset::_M_copy_from_string): Adjust call to _M_copy_from_ptr.
(operator==(const dynamic_bitset&, const dynamic_bitset&))
(operator<(const dynamic_bitset&, const dynamic_bitset&)): Use _M_Nb.
* include/tr2/dynamic_bitset.tcc (dynamic_bitset::_M_copy_from_ptr):
Adjust template parameters to match declaration.
* testsuite/tr2/dynamic_bitset/cmp.cc: New test.
