I can use this in my port from my assembly code part of _ISR_Handler
just before calling the user C Handler. Something like putting
#if CPU_ISR_PASSES_FRAME_POINTER
l.add r4, sp, r0
#endif
where r3 and r4 are the first and second arguments respectively.

Hi all,
I am trying to optimize the _ISR_Handler code. OpenRISC folks
indicated that I can use shadow registers to hold interrupted task
context. There are 512 SPRs that can be used for mapping general
purpose registers to these SPRs (I guess we can use them for nesting
interrupts, given that inte
You don't protect or1k specific code with this. It is only supposed to be used
in generic code. I suspect the generic clock framework has a cast to cover this
