           Summary: -fvisibility=hidden not setting the visibility of the
                    resolver/ifunc created for attribute target
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal

Given the c++ code

int __attribute__((target("sse4.2"))) foo_overload(int);
int __attribute__((target("default"))) foo_overload(int);

int bar() {
  return  foo_overload(1);
}

gcc produces
