creating Intrinsic DAG Node
Matt,
The added intrinsic in DAG looks like:
0xbedb698: i32 = llvm.MyIntrinsic 0xbedb200, 0xbedac18 [ORD=4]
The builtin in DAG looks like:
0xbedb2a8: i32,ch = llvm 0xbedb158:1, 0xbedb200, 0xbedb158 [ORD=7] [ID=16]
The only difference I'm seeing is the extra operand, which is a 'ch'
from a load.
