I looked at the other one. Beyond my question about the name, this looks great!
This is exactly what I was imagining! This will enable the frontend to opt into this optimization without having to touch the optimizer. One nit: can we use a different name than "arc_retain_agnostic". Have you considered something like "arc_inert"? My fear is that at a glance (without thinking), you would think that the attribute would have something only to do with retain when we are really talking about ARC value operations. Beyond that looks great!

I don't remember. That being said, this should be a conservative optimization. What if someone adds in the future a different global where this isn't a no-op. Is it possible if you know what the global is to add a whitelist that you only care about those 2 things.

I do not work on objcarc any longer. +CC Duncan.

Thanks for running it through git-clang-format. LGTM!
Did you run this through git-clang-format?

Chandler: Later tonight I am going to figure out what I need to do to my out of tree project to make this work. Hopefully everything is smooth.

I think that my response via email did not hit phabriactor. So sorry for the delay.

I failed at using fabricator. I am going to close this until I get in the attribute version. That is what I meant to give to Doug to review.

Removed an unneeded static cast.
I also am not appropriate for reviewing this. Resigning as well.

I just prepared all of the code that I need internally to work with this and it enables me to work through/verify all my use cases. This LGTM! Thanks Chandler!

I would comment this a little differently. I think it is good to have the Hacker's Delight mention, but IIRC LLVM has some specific rules about this. I would just ask on the list or irc. The actual implementation looks fine to me (it is exactly the same as hacker's delight).
