AMD's own optimizing compiler is also LLVM-based. So, we now can wind up with the situation of both compilers adding spiffy optimizations and then never upstreaming them.
It's less of a problem if the two of them don't decide to add their own proprietary "extensions" to the language. That may be something to look out for going forward.
