TableGen has support for using an intrinics name directly in a DAG, but this breaks down when referring to just a node, as that's handled initializer list stuff entirely via subclassing in the parser. That is, using an instrinsic like "(int_my_intrinsic ...)" works fine. Using it standalone for parameterizing the operator in such a DAG does not. Fixing this is simple enough, as we simply declare Intrinsic as deriving from SDPatternOperator, which is the class name intended for exactly this purpose in TargetSelectionDAG.td. When the intrinsic is actually used in the DAG pattern, it will be recognized and expanded to an intrinsic_wo_chain (et. al.) just like when it's used directly. Incoming ARM NEON cleanup based on this and a bit of functionality improvement after that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159973 91177308-0d34-0410-b5e6-96231b3b80d8
