clang ToT doesn't build on macOS 10.10 anymore...?

Artem Dergachev via cfe-dev
Hi all,

I just tried updating my clang build on a few machines, and it built fine on 10.11, but on a macOS 10.10 with AppleClang 7.0.2.7000181 I get this:

/Users/builder/llvm/llvm/projects/compiler-rt/lib/builtins/adddf3.c:28:53: error: alias unsupported on this file format
AEABI_RTABI double __aeabi_dadd(double a, double b) COMPILER_RT_ALIAS(__adddf3);
                                                    ^
/Users/builder/llvm/llvm/projects/compiler-rt/lib/builtins/int_lib.h:29:36: note: expanded from macro 'COMPILER_RT_ALIAS'
#define COMPILER_RT_ALIAS(aliasee) _Pragma("GCC error(\"alias unsupported on this file format\")")
                                   ^
<scratch space>:89:6: note: expanded from here
 GCC error("alias unsupported on this file format")
     ^

Should this build?  Is 10.10 supported?

Thanks,

Sean
