Unaligned access is supported on PPC for non-vector types, and is generally more efficient than manually expanding the loads and stores. A few of the existing test cases were using expanded unaligned loads and stores to test other features (like load/store with update), and for these test cases, unaligned access remains disabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177160 91177308-0d34-0410-b5e6-96231b3b80d8
