This changes the SelectionDAG nodes from ISD::INTRINSIC_W_CHAIN to ISD::INTRINSIC_WO_CHAIN which enables easy lowering to equivalent SelectionDAG nodes (e.g. __builtin_msa_sub_w -> ISD::SUB) in future patches since nodes such as ISD::SUB do not have a chain. It also corrects an obvious mistake, namely that the subtract intrinsics were marked as being commutative. As per a similar change in r189106 (http://llvm.org/viewvc/llvm-project?rev=189106&view=rev) there isn’t a new testcase in this patch since the existing tests should test the intrinsics to the same standard and the best I can do for a testcase would be a fragile pass/maybe test of whether memory operations can (and do) cross the intrinsic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189784 91177308-0d34-0410-b5e6-96231b3b80d8
