[LLVMdev] understanding DAG: node creation
Hi Dmitri, If you have such a simple intrinsic which operates on a single register, just lower the intrinsic to a target specific node which is only implemented by a single instruction. Like you were doing before and by using a chain operand. Hard code the instruction to use and define the global register and only pass the instruction the actual variable argument. Hope that helps, Sam Sam
