Michael de Lang b96e2ff9d8 libstdc++: Implement constexpr std::basic_string for C++20 This is only supported for the cxx11 ABI, not for COW strings. libstdc++-v3/ChangeLog: * include/bits/basic_string.h (basic_string, operator""s): Add constexpr for C++20. (basic_string::basic_string(basic_string&&)): Only copy initialized portion of the buffer. (basic_string::basic_string(basic_string&&, const Alloc&)): Likewise. * include/bits/basic_string.tcc (basic_string): Add constexpr for C++20. (basic_string::swap(basic_string&)): Only copy initialized portions of the buffers. (basic_string::_M_replace): Add constexpr implementation that doesn't depend on pointer comparisons. * include/bits/cow_string.h: Adjust comment. * include/ext/type_traits.h (__is_null_pointer): Add constexpr. * include/std/string (erase, erase_if): Add constexpr. * include/std/version (__cpp_lib_constexpr_string): Update value. * testsuite/21_strings/basic_string/cons/char/constexpr.cc: New test. * testsuite/21_strings/basic_string/cons/wchar_t/constexpr.cc: New test. * testsuite/21_strings/basic_string/literals/constexpr.cc: New test. * testsuite/21_strings/basic_string/modifiers/constexpr.cc: New test. * testsuite/21_strings/basic_string/modifiers/swap/char/constexpr.cc: New test. * testsuite/21_strings/basic_string/modifiers/swap/wchar_t/constexpr.cc: New test. * testsuite/21_strings/basic_string/version.cc: New test.		2021-11-16 16:43:20 +00:00
