[Philip Reames via Phabricator via llvm-commits]

reames added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVISelLowering.cpp:11255
   // Get the widened scalar type, e.g. v4i8 -> i64
   unsigned WideScalarBitWidth =
       BaseLdVT.getScalarSizeInBits() * BaseLdVT.getVectorNumElements();

This was my reasoning as well.
