I'm only interested in attaching a metadata string to a function with wirtten its precondition...Since here in the IR reference (http://llvm.org/docs/LangRef.html#metadata-nodes-and-metadata-strings) there is written:
Metadata can be used as function arguments. Here llvm.dbg.value function is using two metadata arguments:call void @llvm.dbg.value(metadata !24, i64 0, metadata !25)
I thought that maybe writing them as a function argument and then reading them could work... there is any other way to do that?Thank you :)
