Adrian,
Your recent commit
https://github.com/llvm-mirror/llvm/commit/e8c5427c
causes build failures for me locally on Mac OSX 10.11.6 using a stock (and I guess fairly old) Xcode Clang.
Is there any way to fix trunk so that your new code is #ifdef’ed out for versions of Clang that don’t support this bizarre __builtin_available(macos 10.12, *) syntax? Or maybe hide it behind a macro?
Thanks in advance,
Arthur
