[Bug ld/4317] New: Undefined symbols in static executable

[hjl at lucon dot org]

bash-3.1$ cat t.c
__thread int x;

int
_start ()
{
  return x;
}
bash-3.1$ make
cc -fPIC -ftls-model=local-dynamic   -c -o t.o t.c
./ld -o foo t.o
nm -u foo
                 U _GLOBAL_OFFSET_TABLE_
                 U __tls_get_addr
bash-3.1$ 

The problem is there is

              /* LD->LE transition:
                 Ensure it is:
                 leaq address@hidden(%rip), %rdi; call address@hidden
                 We change it into:
                 .word 0x6666; .byte 0x66; movl %fs:0, %rax.  */

in elf64-x86-64.c. When the reference to __tls_get_addr is removed, it leaves
undefined symbol in symtab. It is confusing.
