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

; Test: ExternalConstant
|
|
;
|
|
; Description:
|
|
; This regression test helps check whether the instruction combining
|
|
; optimization pass correctly handles global variables which are marked
|
|
; as external and constant.
|
|
;
|
|
; If a problem occurs, we should die on an assert(). Otherwise, we
|
|
; should pass through the optimizer without failure.
|
|
;
|
|
; Extra code:
|
|
; RUN: opt < %s -instcombine
|
|
; END.
