@efriedma-quic We've been discussing the topic of LTOing libc quite a bit internally, and are currently sketching out how this could work. Unsurprisingly, there's quite a lot to think about in both the compiler and linker, and how the two combine in our different versions of LTO, and how that may break in new and fun ways. 

I was wondering if you'd be available to join the libc monthly meeting (5/8 9am PST) to discuss your take on the whole idea?  I'm not sure what time zone you're normally in, but I think there will be quite a number of folks who are interested in making LTO work well with libc's and LLVM libc in particular. I know a few of my team members would like to pick your brain on the subject, as we're sketching our ideas out. I can try to post a short summary of our thoughts either here or on discouse to make the discussion a bit easier as well.
