; 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: analyze -loops %s | grep ' Loop Containing: label %Inner'
;
implementation
void %test() {
br label %Top
Top:
br label %LoopHeader
Next:
br bool false, label %Inner, label %Out
Inner:
br bool false, label %Inner, label %LoopHeader
LoopHeader:
br label %Next
Out:
br bool false, label %Top, label %Done
Done:
ret void
