nios ii provides the nextpc instruction that returns the pc of that instruction plus four.

there doesn't appear to be a hal macro available for using this

instruction from c code. however, it is relatively easy to make one yourself.

just look at the examples in the hal nios2.h file. it is located in your nios ii kit directory under components/altera_nios2/hal/inc.
