            Bug ID: 118524
           Summary: Wrong assembler for string view literals on ARM64 gcc
                    trunk
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

#include <iostream>
#include <string_view>

using namespace std::literals;
constexpr std::string_view s1 = "a\0\0b";
constexpr std::string_view s2 = "c\0\0d"sv;

int main()
{
    std::cout << s1 << s2;
}

See the different output between 14.2 and trunk.

For s1 there is a difference but it must not be wrong.
For s2 the .LC1 is wrong
