> @jh7370, I apologize in advance, but I saw that you recently looked at a patch to add new functionality (new virtual error method) to this part of llvm for working with the yaml format. Could you please look at this patch, because it also adds some new functionality without breaking backward compatibility.

Hi @tgs-sc, I've added this to my backlog. Please note it may take me a while to review - I've just come back from 2 weeks off work and have a lot to catch up on, plus some upcoming deadlines.
