+ structType = value.getType().dyn_cast<LLVM::LLVMType>();
+ assert(structType && "expected llvm type");
}
----------------
Something does not line up here: you are using dyn_cast which is supposed to be expecting a possible nullptr as a result, but then you add adding an assert, which implies this is an impossible case...
If you are using the assert just to get a “nicer” crash, then the pattern should be asserting on “isa<>” and using cast<>
