; A bit of a brittle test - this is testing the specific DWO_id. The
; alternative would be to test two files with different DW_OP_convert values &
; ensuring the DWO IDs differ when the DW_OP_convert parameter differs.

; So if this test ends up being a brittle pain to maintain, updating the DWO ID
; often - add another IR file with a different DW_OP_convert that's otherwise
; identical and demonstrate that they have different DWO IDs.

; SPLIT: 0x00000000: Compile Unit: {{.*}} DWO_id = 0xafd73565c68bc661

; Regression testing a fairly quirky bug where instead of hashing (see above),
; extra bytes would be emitted into the output assembly in no
; particular/intentional section - so let's check they don't show up at all:
; ASM-NOT: .asciz  "\200\200\200"

; CHECK: 0x{{0*}}[[TYPE:.*]]: DW_TAG_base_type
; CHECK-NEXT:                   DW_AT_name ("DW_ATE_unsigned_32")

; CHECK: DW_LLE_offset_pair ({{.*}}): DW_OP_consts +7, DW_OP_convert 0x[[TYPE]], DW_OP_stack_value
