[PATCH] D140531: [X86] Add reduce_*_ep[i|u]8/16 series intrinsics.

[Phoebe Wang via Phabricator via cfe-commits]

pengfei added inline comments.


================
Comment at: clang/lib/Headers/avx512vlbwintrin.h:2806-2814
+/* Vector-reduction arithmetic accepts vectors as inputs and produces scalars as
+ * outputs. This class of vector operation forms the basis of many scientific
+ * computations. In vector-reduction arithmetic, the evaluation off is
+ * independent of the order of the input elements of V.
+
+ * Used bisection method. At each step, we partition the vector with previous
+ * step in half, and the operation is performed on its two halves.

Do we need such comments?
