Meta TODO list: 1. Create a new DAG -> DAG instruction selector, by adding patterns to the instructions. 2. ??? 3. profit! To-do ----- * Keep the address of the constant pool in a register instead of forming its address all of the time. * We can fold small constant offsets into the %hi/%lo references to constant pool addresses as well.
