| ; This test is derived from test/CodeGen/X86/dwarf-headers.ll
 | |
| 
 | |
| ; Looking for DWARF headers to be generated correctly.
 | |
| ; There are 8 variants with 5 formats: v4 CU, v4 TU, v5 normal/partial CU,
 | |
| ; v5 skeleton/split CU, v5 normal/split TU.  Some v5 variants differ only
 | |
| ; in the unit_type code, and the skeleton/split CU differs from normal/partial
 | |
| ; by having one extra field (dwo_id).
 | |
| ; (v2 thru v4 CUs are all the same, and TUs were invented in v4,
 | |
| ; so we don't bother checking older versions.)
 | |
| 
 | |
| ; Test case built from:
 | |
| ;struct S {
 | |
| ;  int s1;
 | |
| ;};
 | |
| ;
 | |
| ;S s;
 | |
| 
 | |
| ; Verify the v4 non-split headers.
 | |
| ; Note that we check the exact offset of the DIEs because that tells us
 | |
| ; the length of the header.
