Was the clang <> GCC 5 ABI incompatibility overcome at some point?

[Ces VLC]

Hi!

I remember a few years ago when a change in GCC 5 caused ABI
incompatibility with clang. I'm searching for updates on this, and it seems
like clang applied the same change eventually, but can they considered
binary compatible at this moment? Is it now safe to link object code coming
from GCC and from clang?

Thanks!
