/* CTF generation for extern variable with defining and non-defining decl
   in the same CU.

   This testcase checks the case when a non-defining decl is followed by
   a defining decl for the same variable.  See PR debug/105089.
   
   In this testcase,  although two CTF array types are generated, only a
   single CTF variable and a single entry in the CTF object info section
   are expected.  */
