Hi, I see this in the Type class: unsigned getSubclassData() const { return SubclassData; } void setSubclassData(unsigned val) { SubclassData = val; // Ensure we don't have any accidental truncation. assert(getSubclassData() == val && "Subclass data too large for field"); } How will the assert ever get triggered? The type is &...

...trSet to make sure I don't visit a type more than once but the fact I would need to do this hints to me that this is probably the wrong approach. - How can I change the address space number associated with a Type? Looking at the implementation it seems that ``getAddressSpace()`` just returns ``getSubclassData()`` and it also looks like I can use ``setSubClassData()`` to set this. What is "Subclass" data for? If I try to set the address space number this way it seems like a **massive** hack which is already broken if Subclass data is used for other things inside LLVM. Just in case someone asks...
