Hello, Thank you very much for the pointers. I am are able to create new MDNodes, filled with some constants, and attach them to llvm instructions. However, the metadata map is not getting updated as expected. For example, instead of the expected new entry !n = metadata !{some values} we are getting !n = metadata !{null} Do you know what might be wrong? Do we need to enter the MDNodes into the

Dear llvm-ers, I am trying to attach a customized metadata to llvm instructions. Let's say, I want to attach some number to each instruction. I am trying to use void Instruction::setMetadata(unsigned KindID, MDNode* Node) but I am not sure how to create a brand new instance of an MDNode. Do you have any code samples demonstrating how to do that? Due to some tool dependencies, I am using
