Comment at: clang/lib/CodeGen/CGExprScalar.cpp:1626-1627
+ // Casting to pointer that does not carry dynamic information (provided by
+ // invariant.group) requires stripping it.
+ Src = Builder.CreateStripInvariantGroup(Src);
> Are there any cases where we need a barrier when the destination type is a dynamic type here?
No, I don't think so. I will also add test for that.
