> Hi @oontvoo. My apologies for the slow responses - I've got a lot of stuff on with my normal work, so don't have as much time to look at LLVM stuff currently. Also, please be warned that I'll be off on PTO for the best part of 3 weeks starting the middle of next week, so won't be able to review this further until some time after I'm back.

This PR has already been under review for a long time; if you are not going to have time to look at it over the next few weeks, could you suggest another reviewer who might have more time and whose approval you would be happy to accept?
