[PATCH] D81619: [NFC] Bail out for scalable vectors before calling getNumElements

[Francesco Petrogalli via Phabricator via llvm-commits]

fpetrogalli added inline comments.


================
Comment at: llvm/lib/Analysis/ConstantFolding.cpp:2697
 
+  SmallVector<Constant *, 4> Result(
+      cast<FixedVectorType>(VTy)->getNumElements());
----------------
Given that from now on the vector is supposed to have a fixed size, maybe it is also worth defining `auto FixedVTy = cast<FixedVectorType>(VTy)` and use `FixedVTy` in place of `VTy` all through the end of the function?
