/* Test BTF generation of BTF_KIND_{CONST,VOLATILE,RESTRICT} records.
BTF const, volatile and restrict records are nameless type records pointing
to the type they modify.
Types:
[1] int 'int' size=4U offset=0 bits=32 SIGNED
[2] const <anonymous> type=1
[3] volatile <anonymous> type=1
[4] const <anonymous> type=3
[5] ptr <anonymous> type=1
[6] restrict <anonymous> type=5
[7] ptr <anonymous> type=2
[8] restrict <anonymous> type=7
Note:
- Type id 3 describes a volatile int.
- Type id 2 describes a const int.
- Type id 4 describes a const volatile int by modifying id 3.
- Type id 6 describes a restrict pointer to int.
- Type id 8 describes a restrict pointer to const int.
