input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81537 91177308-0d34-0410-b5e6-96231b3b80d8

; 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.
