Hi, I would like to transform a LLVM function containing a load and an add of the base address inside a loop to a post-incremented load. In DAGCombiner.cpp::CombineToPostIndexedLoadStore(), it says it cannot fold the add for instance if it is a predecessor/successor of the load. I find this odd, as this is exactly what I would like to handle: a simple loop with an address that is inremented in
