missing documentation for llvm.dbg.label?


In a recent patch, Clang started emitting llvm.dbg.label intrinsics.

I was looking for documentation on this intrinsic on the LangRef and SourceLevelDebugging pages, but there is no reference to this intrinsic there. Is this intentional or maybe I’m looking at the wrong places?


The discussion regarding the debug info for labels was here:

That it's missing from the language reference is an omission.
