1  /* Test Compilation of mixed constructs containing structs and arrays.

       3     Further, the compiler is expected to generate a single CTF struct type for
       4     struct cmodel (due to Type de-duplication at the time of CTF generation).
       5     
       6     const qualifier in fields of structs should be processed.  It appears as a
       7     no-name CTF record with appropriate ctt_info.  In this testcase, there are
       8     two const qualifiers - const char and const struct cmodel.  However, due to
       9     way the debug information is represented in DWARF die, 3 const qualifier
      10     records appear in the CTF section.
