; Check that distinct nodes are emitted before uniqued nodes, even if that
; breaks post-order traversals.
; Nodes in this testcase are numbered to match how they are referenced in
; bitcode. !1 is referenced as opN=1.
; CHECK: <DISTINCT_NODE op0=2/>

; CHECK-NEXT: <NODE op0=1/>

; Before the named records we emit the index containing the position of the
; previously emitted records
; CHECK-NEXT: <INDEX {{.*}} (offset match)
; Note: named metadata nodes are not cannot reference null so their operands
; are numbered off-by-one.
; CHECK-NEXT: <NAME
; CHECK-NEXT: <NAMED_NODE op0=1/>
