[llvm-dev] creating Intrinsic DAG Node

[Ryan Taylor via llvm-dev]

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?
