/* Test compilation of stubs with various qualifiers - const, restrict and
   volatile.

   Testcase includes a std header to allow testing of shared types across
   files.  Only one CTF record for int is expected.
   
   CTF records for CVR qualifiers are no-name records.  In this testcase, there
   are 5 qualifiers across constructs.  2 more no-name CTF records correspond to
   CTF pointer records.

    TYPEID: name string (size) -> ref TYPEID : ref name string (size) -> ...

   Types:
      1: long int (size 0x8)
      2: long unsigned int (size 0x8)
      3: size_t (size 0x8) -> 2: long unsigned int (size 0x8)
      4: int (size 0x4)
      5: const int (size 0x4) -> 4: int (size 0x4)
      6: volatile const int (size 0x4) -> 5: const int (size 0x4) -> 4: int (size 0x4)
      7: long long int (size 0x8)
      8: long double (size 0x10)
      9: int * (size 0x8) -> 4: int (size 0x4)
      a: int *restrict (size 0x8) -> 9: int * (size 0x8) -> 4: int (size 0x4)
      b: const int * (size 0x8) -> 5: const int (size 0x4) -> 4: int (size 0x4)
      c: const int *restrict (size 0x8) -> b: const int * (size 0x8) -> 5: const int (size 0x4) -> 4: int (size 0x4)
      d: INTP (size 0x8) -> 9: int * (size 0x8) -> 4: int (size 0x4)
      e: const INTP (size 0x8) -> d: INTP (size 0x8) -> 9: int * (size 0x8) -> 4: int (size 0x4)
      f: void (size 0x0)
      10: void (*) (size_t, int *restrict, const int *restrict) (size 0x0)
