The SPU ABI does not mention v64, and all examples in C suggest v128 are treated similarily to arrays, we use array alignment for v64 too. This makes the alignment of e.g. [2 x <2 x i32>] behave "intuitively" and similar to as if the elements were e.g. i32s. This also makes an "unaligned store" test to be aligned, with different (but functionally equivalent) code generated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117360 91177308-0d34-0410-b5e6-96231b3b80d8
