Many useful ARM intrinsics (such as fma, rng, ld64b, etc.) are described in Arm C Language Extensions. But the arm_acle.h header file shipped with Xcode not include them.
Are these intrinsics supported by Apple Silicon chip?

When compile source with __bf16 variable, it throw exception, "__bf16 is not supported on this target".
The compiler is xcode build-in clang-1400.0.29.202.
Is Apple silicon support bf16 type?
