[LLVMdev] metadata in callgraph

[Eric Christopher]

So the warning that you're getting is exactly what's going on. You're
trying an old version of the debug information metadata with a newer llvm.
You should likely use a newer clang if you're going to work with a newer
llvm or an older llvm if you're going to work with an older clang.

Thanks!
