   5 # This checks that the operand of DW_OP_call_ref is always parsed corresponding
   6 # to the DWARF format of CU. Our code used to have an exception for verson == 2,
   7 # where it treated the operand like it had the size of address, but since
   8 # DW_OP_call_ref was introduced only in DWARF3, the code could be simplified.
