[PATCH] D109584: Implementing expansion pass for VP load and store.

[Simon Moll via Phabricator via llvm-commits]

simoll added inline comments.


================
Comment at: llvm/lib/CodeGen/ExpandVectorPredication.cpp:785
+  case Intrinsic::vp_store:
+    if (isEVLOnlyMemoryIntrinsic(VPI)) {
+      return expandPredicationInUnfoldedLoadStore(Builder, VPI);

load/store unfolding does not work for scalable vectors this way. We should default to the memory intrinsic path for scalable types.
