Heh so is clangs.

How do you go about creating metadata?

I want to do

!nvvm.annotations = !{!n}
!n = !{void (float*)* @my_kernel, !"kernel", i32 1}

where !n is a unique MDNode.
  so far i have
llvm::NamedMDNode *nnvm_annotations = 
gIR->module.getOrInsertNamedMetadata(StringRef("nnvm.annotations"));
llvm::MDNode *kernel_md_node = new 
llvm::MDNode(gIR->context,???what goes here???);
nnvm_annotations->addOperand(kernel_md_node);

I have access to the function as
  llvm::Function *func;

many thanks
Nic
