; LoopInfo is incorrectly calculating loop nesting! In this case it doesn't
; figure out that loop "Inner" should be nested inside of leep "LoopHeader",
; and instead nests it just inside loop "Top"
;
; RUN: llvm-upgrade < %s | llvm-as | opt -analyze -loops | grep ' Loop Containing:[ ]*%Inner'
;

Inner:
br bool false, label %Inner, label %LoopHeader
LoopHeader:
br label %Next
Out:
