/* CTF forward type is generated for forward declarations of types in C.
   
   Check that the ctf-kind of CTF_K_FOWARD type is CTF_K_STRUCT or CTF_K_UNION.
   For forward types, the compiler encodes the CTF kind in the ctt_type field.
   CTF_K_FORWARD is used as the CTF type as usual in the ctt_info.  */

/* Note - A value of 6 in "ctt_size or ctt_type" appears twice in this
   testcase. This might be misconstrued as  2 CTK_K_FORWARD records of struct
   type.  The second assembler tag is due to a ref type in a CVR CTF record.
   TBD - perhaps a more robust string pattern is needed.  */
