   They must have a size that is a multiple of 4.

   "GDB" is the old, no-longer-supported GDB augmentation.

   The "GDB2" augmentation string specifies the use of the DW_IDX_GNU_*
   attributes.

   The meaning of the "GDB3" augmentation string is identical to "GDB2", except
   for the meaning of DW_IDX_parent.  With "GDB2", DW_IDX_parent represented an
   index in the name table.  With "GDB3", it represents an offset into the entry
   pool.  */
