/* Test Compilation of mixed constructs containing structs and arrays.
Further, the compiler is expected to generate a single CTF struct type for
struct cmodel (due to Type de-duplication at the time of CTF generation).
const qualifier in fields of structs should be processed. It appears as a
no-name CTF record with appropriate ctt_info. In this testcase, there are
two const qualifiers - const char and const struct cmodel. However, due to
way the debug information is represented in DWARF die, 3 const qualifier
records appear in the CTF section.
<1><e1>: Abbrev Number: 14 (DW_TAG_typedef)
<e2> DW_AT_name : (indirect string, offset: 0x114): cmodel_t
<e9> DW_AT_type : <0x9a>
<1><ed>: Abbrev Number: 13 (DW_TAG_const_type)
<ee> DW_AT_type : <0xe1>
<1><f2>: Abbrev Number: 4 (DW_TAG_array_type)
<f3> DW_AT_type : <0xed>
<f7> DW_AT_sibling : <0x102>
<2><101>: Abbrev Number: 0
<1><102>: Abbrev Number: 13 (DW_TAG_const_type)
<103> DW_AT_type : <0xf2>
<1><107>: Abbrev Number: 15 (DW_TAG_variable)
<108> DW_AT_name : (indirect string, offset: 0x57): _models
<10f> DW_AT_type : <0x102>
<1><11d>: Abbrev Number: 0
This results in:
_models -> e: const const cmodel_t [3] (size 0x30) -> d: const cmodel_t [3] (size 0x30)
Deemed as acceptable for now. */
