[PATCH] D152421: [RISCV] Introduce the concept of DLEN(data path width) into getLMULCost.

[Alex Bradbury via Phabricator via llvm-commits]

asb added a comment.

LGTM after you add a doc comment to getDLenFactor.



================
Comment at: llvm/lib/Target/RISCV/RISCVSubtarget.h:182
 
+  unsigned getDLenFactor() const {
+    if (DLenFactor2)
----------------
I think we need a comment here to explain the purpose of the method.
