Hi! StructType has no method for adding elements, but I'd like to build a type incrementally, i.e. it starts empty and a global of the type exists. then load instructions are added to a basic block and for each load instruction an element to the type has to be added. Is there a way to do this? For example I could first use UndefValues instead of load and then do a replaceAllUsesWith when the type is finally known. Does this work or is there a better solution? -Jochen
