Vectorizer tests in the target-independent directory should not have a target triple. If a test really needs to query a specific backend, it belongs in the right target subdirectory (which "REQUIRES" the right backend). Otherwise, it should not specify a triple. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@283512 91177308-0d34-0410-b5e6-96231b3b80d8
