; 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.
