| ; 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. |
