           Summary: ld.gold does not handle R_X86_64_TPOFF64 emitted by

           Product: binutils
           Version: 2.26
            Status: UNCONFIRMED
          Severity: normal

$ cat foo.c 
struct comp {
        unsigned a:8;
        unsigned b:4;
};

__thread struct comp cmp;

__attribute__ ((__noinline__))
void f1(void)
{
        cmp.a = 1;
        cmp.b = 2;
}

int main(void)
{
        f1();

        return 0;
}
$ gcc -mcmodel=large -g foo.c -O -fuse-ld=bfd && echo success
success
$ gcc -mcmodel=large -g foo.c -O -fuse-ld=gold && echo success
/usr/bin/ld.gold: error: /tmp/ccdNc4iz.o: unexpected reloc 18 in object file
foo.c:12: error: unexpected reloc 18 in object file
collect2: error: ld returned 1 exit status

Executable generated by ld.bfd is working correctly.
Bug #12809 is maybe related.
