             Bug #: 13048
           Summary: Invalid x86 tls sequence

           Version: trunk
          Platform: PC

I am getting the following error when linking firefox with gold:

test.o:test.i:function choose_arena: error: TLS relocation against invalid
instruction

The problem is that clang is producing the sequence

  11:   8d 04 1d 00 00 00 00    lea    0x0(,%ebx,1),%eax
  18:   e8 fc ff ff ff          call   19 <choose_arena+0x19>

and the linker expects

  11:   8d 83 00 00 00 00       lea    0x0(%ebx),%eax
  17:   e8 fc ff ff ff          call   18 <choose_arena+0x18>
