; This test checks to make sure that 'br X, Dest, Dest' is folded into
; 'br Dest'. This can only happen after the 'Z' block is eliminated. This is
; due to the fact that the SimplifyCFG function does not use
; the ConstantFoldTerminator function.
; RUN: as < %s | opt -simplifycfg | dis | not grep 'br bool %c2'
declare void %noop()
int %test(bool %c1, bool %c2) {
call void %noop()
br bool %c1, label %A, label %Y
A:
call void %noop()
br bool %c2, label %Z, label %X ; Can be converted to unconditional br
Z:
br label %X
X:
call void %noop()
ret int 0
Y:
call void %noop()
br label %X
}
