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

; PR1280 - we should be able to reduce this function to a trunc/sext but it
|
|
; would involve using a bit width (24) that doesn't match a size that
|
|
; the back end can handle. This test makes sure that such a transform
|
|
; is not done. It should be removed when code gen supports "funny"
|
|
; bit widths.
