Hi, where is this function being referenced ? Should extra handling be added in this method - https://github.com/openjdk/panama-vector/blob/113ec5d22a8f1eff42e84e7c30472c78f89d7a36/src/hotspot/share/opto/vectorIntrinsics.cpp#L349 to generate a call to this function - VectorNode::opcode(int sopc) added in this PR ?
