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