--- Comment #7 from Eric Christopher <echristo at gmail.com> ---
We now correctly warn in ToT:

dzur:~/tmp> ~/builds/build-llvm/Debug+Asserts/bin/clang -c foo.c
foo.c:13:10: error: '__builtin_ia32_pshufb256' needs target feature avx2
  return __builtin_ia32_pshufb256(v, key32);
         ^
1 error generated.
