Matt,
Is this an example you are talking about:
LoadedVect = DAG.getNode
<http://llvm.org/docs/doxygen/html/classllvm_1_1SelectionDAG.html#ab02868bea897db34232413f1929ade1d>
(ISD::INTRINSIC_WO_CHAIN
<http://llvm.org/docs/doxygen/html/namespacellvm_1_1ISD.html#a22ea9cec080dd5f4f47ba234c2f59110ac771b9cda3b889242d457cc4d9b2159c>,
dl, MVT::v4f64,
DAG.getConstant
<http://llvm.org/docs/doxygen/html/classllvm_1_1SelectionDAG.html#adf7343dcb7fff67cf516abca4c1d6793>(Intrinsic::ppc_qpx_qvfcfidu,
dl, MVT::i32),
LoadedVect);
Something like this?

Matt, This seems to generate llvm.my_intrinsic just fine in the DAG, so no DAG errors; however, it won't match. For example, if I call the intrinsic from C, the DAG node looks to be named the same in dotty file but it won't match... am I missing something? I've done it exactly the way it was done above. The DAG looks great but it won't match. Did I miss something? Thanks.
