Nios II, interrupts and internal controller

Does any one know if it is possible to setup a Nios II, with internal interrupt controller using shadow register sets? And how does you specify what register set to use for each interrupt?

I'm sure I'd just checked the docs :-)

In that case you need to execute an 'iret' having set the approriate saved status to the required value.

Actualy it is an 'eret', see page 3-28
