I have a piece of debuginfo containing this subfunction :

DW_TAG_subprogram [6] *
   DW_AT_low_pc [DW_FORM_addr]   (0x0000000000437020)
   DW_AT_high_pc [DW_FORM_data4] (0x0000001e)
   DW_AT_frame_base [DW_FORM_exprloc]    (<0x1> 55 )
   DW_AT_linkage_name [DW_FORM_strp]     ( .debug_str[0x000000ae] = 
   DW_AT_name [DW_FORM_strp]     ( .debug_str[0x000000cb] = "AA")
   DW_AT_decl_line [DW_FORM_data1]       (16)
DW_AT_external [DW_FORM_flag_present] (true)

It's part (a member) of this type:
DW_TAG_structure_type [2] *
   DW_AT_name [DW_FORM_strp] ( .debug_str[0x00000065] = "issudebugtest.ABC")
  DW_AT_byte_size [DW_FORM_data1] (0x08)

How do I get the dw_at_name field? I don't need lldb to decypher the 
mangling I use, I just want access to the linkage name and real encoded 

Also how do I get the type this is contained in (presuming there is one 

Lastly: How do I encode if a method is static or not, I couldn't find 
any difference in what C++ does for instance vs static.
