gdb does not implement the DW_OP_form_tls_address opcode.
This is part of dwarf 4, and gcc can optionally emit it.

GCC only emits it for emutls systems.
In this case the value on the stack is the address of the control variable.
See gcc/emutls.c for more info.
Note that this means that this operator is not equivalent to
DW_OP_GNU_push_tls_address.
