Comment at: llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp:2020
+  const Align Alignment =
+      std::max(std::min(PrefAlign, StackAlign), Align(minAlign));
+  return CreateStackTemporary(VT.getStoreSize(), Alignment);
----------------
Can you split this patch up into two patches:
- one that prevents the stack temporary to exceed the stack alignment (which also needs tests for fixed-width vectors). Please also add @efriedma as reviewer to these patches, since he recently fixed a very similar problem in D79532.
- another to make createStackTemporary support scalable types.
