; 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'
