+ llvm::StructType *STy = dyn_cast<llvm::StructType>(Val->getType());
+ if (STy && STy->canLosslesslyBitCastTo(Dest.getElementType())) {
for (unsigned i = 0, e = STy->getNumElements(); i != e; ++i) {
----------------
Intuitively, I feel like `canLosslesslyBitCastTo` should be used in conjuction
with something like `Builder.CreateBitcast` and after a quick skim through
existing I can't find any uses with `CreateStore` in the codebase. This leads
me to think that we need to call a different function here. As mentioned
earlier, I may be completely wrong as I don't have much experience with codegen.
I will let @jyknight sanity-check my intuition.
