[PATCH] D116890: [RISCV] Add initial support for getRegUsageForType and getNumberOfRegisters

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVTargetTransformInfo.cpp:289
+    if (ST->useRVVForFixedLengthVectors())
+      return divideCeil(Size, ST->getMinRVVVectorSizeInBits());
+  }
----------------
Does this give a different answer than what the default implementation using getTypeLegalizationCost would give?
