[LLVMdev] RFC: Supporting different sized address space arithmetic
...nterTy implementation with no arguments query for the default address space. In SelectionDAG * Add a new API to getIntPtrConstant that takes an address space as the second argument * Modify the implementation of the original getIntPtrConstant function to call the new function with getDefaultAddressSpace(). Modify SelectionDAGBuilder::visitGetElementPtr to get the address space of pointer argument and passing it into the getIntrPtrConstant and getPointerTy calls. As far as I can tell, this should not affect any backends behavior, but will allow the targets with disjoint address spaces to directly...
