craig.topper added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVTargetTransformInfo.cpp:285
+  if (Ty->isVectorTy()) {
+    if (Size.isScalable())
+      return divideCeil(Size.getKnownMinValue(), RISCV::RVVBitsPerBlock);
----------------
Do we need to check the V extension is enabled here?
