Chandler Carruth c1c37734ad [SROA] The original refactoring inspired by the addrspace patch in ... D1764, which in turn set off the other refactorings to make 'getSliceAlign()' a sensible thing. There are two possible inputs to the required alignment of a memory transfer intrinsic: the alignment constraints of the source and the destination. If we are *only* introducing a (potentially new) offset onto one side of the transfer, we don't need to consider the alignment constraints of the other side. Use this to simplify the logic feeding into alignment computation for unsplit transfers. Also, hoist the clamp of the magical zero alignment for these intrinsics to the more customary one alignment early. This lets several other conditions melt away. No functionality changed. There is a further improvement this exposes which *will* change functionality, but that's arriving in a separate patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202232 91177308-0d34-0410-b5e6-96231b3b80d8		2014-02-26 05:33:36 +00:00
