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 shows an alloca of a struct and an array that can be reduced to
|
|
; multiple variables easily. However, the alloca is used by a store
|
|
; instruction, which was not possible before aggregrates were first class
|
|
; values. This checks of scalarrepl splits up the struct and array properly.
