rjmccall added inline comments.

 * SPIR
-* X86 (Only available under feature AVX512-FP16)
+* X86 (Enabled with feature SSE2 and up)
 
----------------
Could you take the wording I suggested from the other patch?  You'll need to 
drop the part about avoiding intermediate truncations, but it's important to 
still document the practical/performance difference when AVX512-FP16 is not 
available, even if the observable behavior is the same.


================
Comment at: clang/docs/ReleaseNotes.rst:517
 
+- Support for ``_Float16`` type has been added.

----------------



================
Comment at: clang/test/SemaCXX/Float16.cpp:4
+// RUN: %clang_cc1 -fsyntax-only -verify -triple armv7a-linux-gnu %s
+// RUN: %clang_cc1 -fsyntax-only -verify -triple aarch64-linux-gnu %s
 
----------------
This test (and Float16.c) should continue to have positive and negative 
examples even if generic x86_64 is no longer negative.  Generic i386 should 
still be negative, for example.
