We support `float` -> `bf16` in `AVX512BF16`. https://www.intel.com/content/www/us/en/docs/intrinsics-guide/index.html#avx512techs=AVX512_BF16 And we found some problems in how to represent `bf16` types in intrinsics. For example, we currently defined `__bfloat16` as `unsigned short`. We cannot stop user e.g., adding 2 `__bfloat16` in C code and getting the wrong result. So we want to introduce the type on X86.
